The impact of goal saliency and verbal information on selective imitation in 16- to 18-month-olds. INFANCY 2024. [PMID: 38767109 DOI: 10.1111/infa.12601] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2022] [Revised: 12/21/2023] [Accepted: 04/26/2024] [Indexed: 05/22/2024]
Abstract
This study aimed to assess which action component (movement or goal) infants prioritize in their imitation behavior when they get information about its relevance from two important sources: perceptual goal saliency and experimenter's verbal information. 16- to 18-month-olds (N = 72) observed how the experimenter moved a toy mouse with a hopping or sliding movement onto one of two empty spaces (low goal saliency) or 2D circles (medium saliency), or inside one of two 3D houses (high saliency). Before the demonstration, the experimenter verbally announced the movement style or the goal. Results showed that verbal action descriptions did not influence infants' imitation. However, matching previous findings, infants imitated the goal more often than the movement in the high-saliency condition, and the movement more often than the goal in the low-saliency condition. Moreover, in the novel medium-saliency condition, infants imitated both components equally often. Thus, selective imitation varied as a function of perceptual goal saliency, but not of verbal cues. This suggests that perceptual features can enhance infants' bottom-up processing and imitation of action components, while the impact of top-down processes based on verbal cues may vary depending on task characteristics and infants' verbal abilities, inducing a need for further research.

Profiles of executive functions in middle childhood and prediction of later self-regulation. Front Psychol 2024; 15:1379126. [PMID: 38784608 PMCID: PMC11111993 DOI: 10.3389/fpsyg.2024.1379126] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2024] [Accepted: 04/01/2024] [Indexed: 05/25/2024] Open
Abstract
Most research on the development of executive functions (EF) has applied variable-oriented approaches, neglecting the potential inter- and intraindividual interplay of these capacities. In a person-oriented approach, the present study identified varying profiles of performance for three cool EF facets: inhibition, working-memory updating, and cognitive flexibility, as well as two hot EF facets: affective decision-making and delay of gratification, in a community sample of 1,657 children (T1; age: 6-11 years, M = 8.36 years, 52.1% female) via latent profile analysis. The best-fitting model allowed for partial dependence across the three cool EF and included four profiles: all-average (69.4% of the children), low-delay (19.0%), regulated-decision-making (7.0%), and low-inhibition (4.6%). Age, binary sex, socio-economic status, multilingualism, and processing speed were identified as significant characteristics of EF profile membership. Longitudinally, a higher probability of belonging to the low-inhibition profile predicted lower rates of the self-regulatory outcome of inhibitory control 1 year later, while belonging to the regulated-decision-making profile predicted lower rates of the ability to plan and organize 3 years later. These results not only demonstrate the existence of subgroups with different concurrent within-person expressions of EF performance, but also identify related characteristics and longitudinal outcomes of subgroup membership. In turn, these conclusions stress the importance of person-oriented research to inform on differing weaknesses or strengths in EF performance for varying individuals, thereby providing valuable insight for educational and clinical research into the design of effective personalized support or interventions during middle childhood.

Better in sync: Temporal dynamics explain multisensory word-action-object learning in early development. INFANCY 2024.

Abstract
We investigated the temporal impact of multisensory settings on children's learning of word-object and action-object associations at 1- and 2-years of age. Specifically, we examined whether the temporal alignment of words and actions influenced the acquisition of novel word-action-object associations. We used a preferential looking and violation of expectation task in which infants and young children were first presented with two distinct word-object and action-object pairings either in a synchronous (overlapping in time) or sequential manner (one after the other). Findings revealed that 2-year-olds recognized both, action-object and word-object associations when they first saw the word-action-object combinations synchronously, but not sequentially, as evidenced by looking behavior. 1-year-olds did not show evidence for recognition for either of the word-object and action-object pairs, regardless of the initial temporal alignment of these cues. To control for individual differences, we explored factors that might influence associative learning based on parental reports of 1- and 2-year-olds development, however, developmental measures did not explain word-action-object associative learning in either group. We discuss that while young children may benefit from the temporal alignment of multisensory cues as it enables them to actively engage with the multisensory content in real-time, infants may have been overwhelmed by the complexity of this input.

Mother-infant social gaze dynamics relate to infant brain activity and word segmentation. Dev Cogn Neurosci 2024; 65:101331.

Abstract
The 'social brain', consisting of areas sensitive to social information, supposedly gates the mechanisms involved in human language learning. Early preverbal interactions are guided by ostensive signals, such as gaze patterns, which are coordinated across body, brain, and environment. However, little is known about how the infant brain processes social gaze in naturalistic interactions and how this relates to infant language development. During free-play of 9-month-olds with their mothers, we recorded hemodynamic cortical activity of ´social brain` areas (prefrontal cortex, temporo-parietal junctions) via fNIRS, and micro-coded mother's and infant's social gaze. Infants' speech processing was assessed with a word segmentation task. Using joint recurrence quantification analysis, we examined the connection between infants' ´social brain` activity and the temporal dynamics of social gaze at intrapersonal (i.e., infant's coordination, maternal coordination) and interpersonal (i.e., dyadic coupling) levels. Regression modeling revealed that intrapersonal dynamics in maternal social gaze (but not infant's coordination or dyadic coupling) coordinated significantly with infant's cortical activity. Moreover, recurrence quantification analysis revealed that intrapersonal maternal social gaze dynamics (in terms of entropy) were the best predictor of infants' word segmentation. The findings support the importance of social interaction in language development, particularly highlighting maternal social gaze dynamics.

Words and arbitrary actions in early object categorization: weak evidence for a word advantage. ROYAL SOCIETY OPEN SCIENCE 2024; 11:230648.

Abstract
Both words and gestures have been shown to influence object categorization, often even overriding perceptual similarities to cue category membership. However, gestures are often meaningful to infants while words are arbitrarily related to an object they refer to, more similar to arbitrary actions that can be performed on objects. In this study, we examine how words and arbitrary actions shape category formation. Across three conditions (word cue, action cue, word-action cue), we presented infants (N = 90) with eight videos of single-category objects which vary in colour and other perceptual features. The objects were either accompanied by a word and/or an action that is being performed on the object. Infants in the word and action condition showed a decrease in looking over the course of the familiarization phase indicating habituation to the category, but infants in the word-action condition did not. At test, infants saw a novel object of the just-learned category and a novel object from another category side-by-side on the screen. There was some evidence for an advantage for words in shaping early object categorization, although we note that this was not robust across analyses.

Tool mastering today - an interdisciplinary perspective. Front Psychol 2023; 14:1191792.

Abstract
Tools have coined human life, living conditions, and culture. Recognizing the cognitive architecture underlying tool use would allow us to comprehend its evolution, development, and physiological basis. However, the cognitive underpinnings of tool mastering remain little understood in spite of long-time research in neuroscientific, psychological, behavioral and technological fields. Moreover, the recent transition of tool use to the digital domain poses new challenges for explaining the underlying processes. In this interdisciplinary review, we propose three building blocks of tool mastering: (A) perceptual and motor abilities integrate to tool manipulation knowledge, (B) perceptual and cognitive abilities to functional tool knowledge, and (C) motor and cognitive abilities to means-end knowledge about tool use. This framework allows for integrating and structuring research findings and theoretical assumptions regarding the functional architecture of tool mastering via behavior in humans and non-human primates, brain networks, as well as computational and robotic models. An interdisciplinary perspective also helps to identify open questions and to inspire innovative research approaches. The framework can be applied to studies on the transition from classical to modern, non-mechanical tools and from analogue to digital user-tool interactions in virtual reality, which come with increased functional opacity and sensorimotor decoupling between tool user, tool, and target. By working towards an integrative theory on the cognitive architecture of the use of tools and technological assistants, this review aims at stimulating future interdisciplinary research avenues.

Self-regulation as a resource for coping with developmental challenges during middle childhood and adolescence: the prospective longitudinal PIER YOUTH-study. BMC Psychol 2023; 11:97.

Abstract
BACKGROUND Self-regulation (SR) as the ability to regulate one's own physical state, emotions, cognitions, and behavior, is considered to play a pivotal role in the concurrent and subsequent mental and physical health of an individual. Although SR skills encompass numerous sub-facets, previous research has often focused on only one or a few of these sub-facets, and only rarely on adolescence. Therefore, little is known about the development of the sub-facets, their interplay, and their specific contributions to future developmental outcomes, particularly in adolescence. To fill these research gaps, this study aims to prospectively examine (1) the development of SR and (2) their influence on adolescent-specific developmental outcomes in a large community sample. METHODS/DESIGN Based on previously collected data from the Potsdam Intrapersonal Developmental Risk (PIER) study with three measurement points, the present prospective, longitudinal study aims to add a fourth measurement point (PIERYOUTH). We aim to retain at least 1074 participants now between 16 and 23 years of the initially 1657 participants (6-11 years of age at the first measurement point in 2012/2013; 52.2% female). The study will continue to follow a multi-method (questionnaires, physiological assessments, performance-based computer tasks), multi-facet (assessing various domains of SR), and multi-rater (self-, parent-, and teacher-report) approach. In addition, a broad range of adolescent-specific developmental outcomes is considered. In doing so, we will cover the development of SR and relevant outcomes over the period of 10 years. In addition, we intend to conduct a fifth measurement point (given prolonged funding) to investigate development up to young adulthood. DISCUSSION With its broad and multimethodological approach, PIERYOUTH aims to contribute to a deeper understanding of the development and role of various SR sub-facets from middle childhood to adolescence. The large sample size and low drop-out rates in the first three measurements points form a sound database for our present prospective research.

Interoceptive accuracy is associated with benefits in decision making in children. Front Psychol 2023; 13:1070037.

Abstract
Introduction Decision making results not only from logical analyses, but seems to be further guided by the ability to perceive somatic information (interoceptive accuracy). Relations between interoceptive accuracy and decision making have been exclusively studied in adults and with regard to complex, uncertain situations (as measured by the Iowa Gambling Task, IGT). Methods In the present study, 1454 children (6-11 years) were examined at two time points (approximately 1 year apart) using an IGT as well as a delay-of-gratification task for sweets-items and toy-items. Interoceptive accuracy was measured using a child-adapted version of the Heartbeat Perception Task. Results The present results revealed that children with higher, as compared to lower, interoceptive accuracy showed more advantageous choices in the IGT and delayed more sweets-items, but not toy-items, in a delay-of-gratification task at time point 2 but not at time point 1. However, no longitudinal relation between interoceptive accuracy and decision making 1 year later could be shown. Discussion Results indicate that interoceptive accuracy relates to decision-making abilities in situations of varying complexity already in middle childhood, and that this link might consolidate across the examined 1-year period. Furthermore, the association of interoceptive accuracy and the delay of sweets-items might have implications for the regulation of body weight at a later age.

The role of mother-infant emotional synchrony in speech processing in 9-month-old infants. Infant Behav Dev 2022; 69:101772.

Abstract
Rhythmicity characterizes both interpersonal synchrony and spoken language. Emotions and language are forms of interpersonal communication, which interact with each other throughout development. We investigated whether and how emotional synchrony between mothers and their 9-month-old infants relates to infants' word segmentation as an early marker of language development. Twenty-six 9-month-old infants and their German-speaking mothers took part in the study. To measure emotional synchrony, we coded positive, neutral and negative emotional expressions of the mothers and their infants during a free play session. We then calculated the degree to which the mothers' and their infants' matching emotional expressions followed a predictable pattern. To measure word segmentation, we familiarized infants with auditory text passages and tested how long they looked at the screen while listening to familiar versus novel words. We found that higher levels of predictability (i.e. low entropy) during mother-infant interaction is associated with infants' word segmentation performance. These findings suggest that individual differences in word segmentation relate to the complexity and predictability of emotional expressions during mother-infant interactions.

The Impact of Action Effects on Infants' Predictive Gaze Shifts for a Non-Human Grasping Action at 7, 11, and 18 Months. Front Psychol 2021; 12:695550.

Abstract
During the observation of goal-directed actions, infants usually predict the goal at an earlier age when the agent is familiar (e.g., human hand) compared to unfamiliar (e.g., mechanical claw). These findings implicate a crucial role of the developing agentive self for infants’ processing of others’ action goals. Recent theoretical accounts suggest that predictive gaze behavior relies on an interplay between infants’ agentive experience (top-down processes) and perceptual information about the agent and the action-event (bottom-up information; e.g., agency cues). The present study examined 7-, 11-, and 18-month-old infants’ predictive gaze behavior for a grasping action performed by an unfamiliar tool, depending on infants’ age-related action knowledge about tool-use and the display of the agency cue of producing a salient action effect. The results are in line with the notion of a systematic interplay between experience-based top-down processes and cue-based bottom-up information: Regardless of the salient action effect, predictive gaze shifts did not occur in the 7-month-olds (least experienced age group), but did occur in the 18-month-olds (most experienced age group). In the 11-month-olds, however, predictive gaze shifts occurred only when a salient action effect was presented. This sheds new light on how the developing agentive self, in interplay with available agency cues, supports infants’ action-goal prediction also for observed tool-use actions.

Emergent Goal-Anticipatory Gaze in Infants via Event-Predictive Learning and Inference. Cogn Sci 2021; 45:e13016.

Abstract
From about 7 months of age onward, infants start to reliably fixate the goal of an observed action, such as a grasp, before the action is complete. The available research has identified a variety of factors that influence such goal-anticipatory gaze shifts, including the experience with the shown action events and familiarity with the observed agents. However, the underlying cognitive processes are still heavily debated. We propose that our minds (i) tend to structure sensorimotor dynamics into probabilistic, generative event-predictive, and event boundary predictive models, and, meanwhile, (ii) choose actions with the objective to minimize predicted uncertainty. We implement this proposition by means of event-predictive learning and active inference. The implemented learning mechanism induces an inductive, event-predictive bias, thus developing schematic encodings of experienced events and event boundaries. The implemented active inference principle chooses actions by aiming at minimizing expected future uncertainty. We train our system on multiple object-manipulation events. As a result, the generation of goal-anticipatory gaze shifts emerges while learning about object manipulations: the model starts fixating the inferred goal already at the start of an observed event after having sampled some experience with possible events and when a familiar agent (i.e., a hand) is involved. Meanwhile, the model keeps reactively tracking an unfamiliar agent (i.e., a mechanical claw) that is performing the same movement. We qualitatively compare these modeling results to behavioral data of infants and conclude that event-predictive learning combined with active inference may be critical for eliciting goal-anticipatory gaze behavior in infants.

Kinematic boundary cues modulate 12-month-old infants' segmentation of action sequences: An ERP study. Neuropsychologia 2021; 159:107916.

Abstract
Human infants can segment action sequences into their constituent actions already during the first year of life. However, work to date has almost exclusively examined the role of infants' conceptual knowledge of actions and their outcomes in driving this segmentation. The present study examined electrophysiological correlates of infants' processing of lower-level perceptual cues that signal a boundary between two actions of an action sequence. Specifically, we tested the effect of kinematic boundary cues (pre-boundary lengthening and pause) on 12-month-old infants' (N = 27) processing of a sequence of three arbitrary actions, performed by an animated figure. Using the Event-Related Potential (ERP) approach, evidence of a positivity following the onset of the boundary cues was found, in line with previous work that has found an ERP positivity (Closure Positive Shift, CPS) related to boundary processing in auditory stimuli and action sequences in adults. Moreover, an ERP negativity (Negative Central, Nc) indicated that infants' encoding of the post-boundary action was modulated by the presence or absence of prior boundary cues. We therefore conclude that 12-month-old infants are sensitive to lower-level perceptual kinematic boundary cues, which can support segmentation of a continuous stream of movement into individual action units.

Abstract
When infants observe a human grasping action, experience-based accounts predict that all infants familiar with grasping actions should be able to predict the goal regardless of additional agency cues such as an action effect. Cue-based accounts, however, suggest that infants use agency cues to identify and predict action goals when the action or the agent is not familiar. From these accounts, we hypothesized that younger infants would need additional agency cues such as a salient action effect to predict the goal of a human grasping action, whereas older infants should be able to predict the goal regardless of agency cues. In three experiments, we presented 6-, 7-, and 11-month-olds with videos of a manual grasping action presented either with or without an additional salient action effect (Exp. 1 and 2), or we presented 7-month-olds with videos of a mechanical claw performing a grasping action presented with a salient action effect (Exp. 3). The 6-month-olds showed tracking gaze behavior, and the 11-month-olds showed predictive gaze behavior, regardless of the action effect. However, the 7-month-olds showed predictive gaze behavior in the action-effect condition, but tracking gaze behavior in the no-action-effect condition and in the action-effect condition with a mechanical claw. The results therefore support the idea that salient action effects are especially important for infants' goal predictions from 7 months on, and that this facilitating influence of action effects is selective for the observation of human hands.

Abstract
Studies show relations between executive function (EF), Theory of Mind (ToM), and conduct-problem (CP) symptoms. However, many studies have involved cross-sectional data, small clinical samples, pre-school children, and/or did not consider potential mediation effects. The present study examined the longitudinal relations between EF, ToM abilities, and CP symptoms in a population-based sample of 1,657 children between 6 and 11 years (T1: M = 8.3 years, T2: M = 9.1 years; 51.9% girls). We assessed EF skills and ToM abilities via computerized tasks at first measurement (T1), CP symptoms were rated via parent questionnaires at T1 and approximately 1 year later (T2). Structural-equation models showed a negative relation between T1 EF and T2 CP symptoms even when controlling for attention-deficit hyperactivity disorder (ADHD) symptoms and other variables. This relation was fully mediated by T1 ToM abilities. The study shows how children’s abilities to control their thoughts and behaviors and to understand others’ mental states interact in the development of CP symptoms.

Word-object and action-object association learning across early development. PLoS One 2019; 14:e0220317.

Abstract
Successful communication often involves comprehension of both spoken language and observed actions with and without objects. Even very young infants can learn associations between actions and objects as well as between words and objects. However, in daily life, children are usually confronted with both kinds of input simultaneously. Choosing the critical information to attend to in such situations might help children structure the input, and thereby, allow for successful learning. In the current study, we therefore, investigated the developmental time course of children's and adults' word and action learning when given the opportunity to learn both word-object and action-object associations for the same object. All participants went through a learning phase and a test phase. In the learning phase, they were presented with two novel objects which were associated with a distinct novel name (e.g., "Look, a Tanu") and a distinct novel action (e.g., moving up and down while tilting sideways). In the test phase, participants were presented with both objects on screen in a baseline phase, then either heard one of the two labels or saw one of the two actions in a prime phase, and then saw the two objects again on screen in a recognition phase. Throughout the trial, participants' target looking was recorded to investigate whether participants looked at the target object upon hearing its label or seeing its action, and thus, would show learning of the word-object and action-object associations. Growth curve analyses revealed that 12-month-olds showed modest learning of action-object associations, 36-month-olds learned word-object associations, and adults learned word-object and action-object associations. These results highlight how children attend to the different information types from the two modalities through which communication is addressed to them. Over time, with increased exposure to systematic word-object mappings, children attend less to action-object mappings, with the latter potentially being mediated by word-object learning even in adulthood. Thus, choosing between different kinds of input that may be more relevant in their rich environment encompassing different modalities might help learning at different points in development.

Consistency of co-occurring actions influences young children's word learning. ROYAL SOCIETY OPEN SCIENCE 2019; 6:190097.

Abstract
Communication with young children is often multimodal in nature, involving, for example, language and actions. The simultaneous presentation of information from both domains may boost language learning by highlighting the connection between an object and a word, owing to temporal overlap in the presentation of multimodal input. However, the overlap is not merely temporal but can also covary in the extent to which particular actions co-occur with particular words and objects, e.g. carers typically produce a hopping action when talking about rabbits and a snapping action for crocodiles. The frequency with which actions and words co-occurs in the presence of the referents of these words may also impact young children's word learning. We, therefore, examined the extent to which consistency in the co-occurrence of particular actions and words impacted children's learning of novel word-object associations. Children (18 months, 30 months and 36-48 months) and adults were presented with two novel objects and heard their novel labels while different actions were performed on these objects, such that the particular actions and word-object pairings always co-occurred (Consistent group) or varied across trials (Inconsistent group). At test, participants saw both objects and heard one of the labels to examine whether participants recognized the target object upon hearing its label. Growth curve models revealed that 18-month-olds did not learn words for objects in either condition, and 30-month-old and 36- to 48-month-old children learned words for objects only in the Consistent condition, in contrast to adults who learned words for objects independent of the actions presented. Thus, consistency in the multimodal input influenced word learning in early childhood but not in adulthood. In terms of a dynamic systems account of word learning, our study shows how multimodal learning settings interact with the child's perceptual abilities to shape the learning experience.

Parallels in Processing Boundary Cues in Speech and Action. Front Psychol 2019; 10:1566.

Abstract
Speech and action sequences are continuous streams of information that can be segmented into sub-units. In both domains, this segmentation can be facilitated by perceptual cues contained within the information stream. In speech, prosodic cues (e.g., a pause, pre-boundary lengthening, and pitch rise) mark boundaries between words and phrases, while boundaries between actions of an action sequence can be marked by kinematic cues (e.g., a pause, pre-boundary deceleration). The processing of prosodic boundary cues evokes an Event-related Potentials (ERP) component known as the Closure Positive Shift (CPS), and it is possible that the CPS reflects domain-general cognitive processes involved in segmentation, given that the CPS is also evoked by boundaries between subunits of non-speech auditory stimuli. This study further probed the domain-generality of the CPS and its underlying processes by investigating electrophysiological correlates of the processing of boundary cues in sequences of spoken verbs (auditory stimuli; Experiment 1; N = 23 adults) and actions (visual stimuli; Experiment 2; N = 23 adults). The EEG data from both experiments revealed a CPS-like broadly distributed positivity during the 250 ms prior to the onset of the post-boundary word or action, indicating similar electrophysiological correlates of boundary processing across domains, suggesting that the cognitive processes underlying speech and action segmentation might also be shared.

Cool executive functioning predicts not only mean levels but also individual 3-year growth trajectories of zBMI in elementary-school children. INTERNATIONAL JOURNAL OF BEHAVIORAL DEVELOPMENT 2019.

Abstract
Executive functions (EFs) may help children to regulate their food-intake in an “obesogenic” environment, where energy-dense food is easily available. There is mounting evidence that overweight is associated with diminished hot and cool EFs, and several longitudinal studies found evidence for a predictive effect of hot EFs on children’s bodyweight, but longitudinal research examining the effect of cool EF on weight development in children is still scarce. The current 3-year longitudinal study examined the effect of a latent cool EF factor, which was based on three behavioral EF tasks, on subsequent mean levels and 3-year growth trajectories of body-mass-index z-scores (zBMI). Data from a large sample of children, with zBMI ranging from normal weight to obesity ( n = 1474, aged 6–11 years at T1, 52% girls) was analyzed using structural-equation modeling and linear latent growth-curve modeling. Cool EF at the first wave (T1) negatively predicted subsequent zBMI and zBMI development throughout the 3-year period in middle childhood such that children with better EF had a lower zBMI and less steep zBMI growth. These effects were not moderated by the children’s age or gender. In conclusion, as early as in middle childhood, cool EFs seem to support the self-regulation of food-intake and consequently may play a causal role in the multifactorial etiology of overweight.

Development of hot and cool executive functions in middle childhood: Three-year growth curves of decision making and working memory updating. J Exp Child Psychol 2018; 173:187-204.

Abstract
Although middle childhood is an important period for the development of hot and cool executive functions (EFs), longitudinal studies investigating trajectories of childhood EF development are still limited and little is known about predictors for individual developmental trajectories. The current study examined the development of two typical facets of cool and hot EFs over a 3-year period during middle childhood, comparing a younger cohort (6- and 7-year-olds at the first wave [T1]; n = 621) and an older cohort (8- and 9-year-olds at T1; n = 975) of children. "Cool" working memory updating (WM) was assessed using a backward digit span task, and "hot" decision making (DM) was assessed using a child variant of the Iowa Gambling Task. Linear latent growth curve analyses revealed evidence for developmental growth as well as interindividual variance in the initial level and rate of change in both EF facets. Initial level of WM was positively associated with age (both between and within cohorts), socioeconomic status, verbal ability, and processing speed, whereas initial levels of DM were, in addition to a (potentially age-related) cohort effect, exclusively predicted by gender, with boys outperforming girls. None of the variables predicted the rate of change, that is, the developmental trajectories. However, younger children, as compared with older children, had slightly steeper WM growth curves over time, hinting at a leveling off in the development of WM during middle childhood. In sum, these data add important evidence to the understanding of hot and cool EF development during middle childhood.

Differential effects of others' emotional cues on 18-month-olds' preferential reproduction of observed actions. Infant Behav Dev 2018; 51:60-70.

Abstract
Infants use others' emotional signals to regulate their own object-directed behavior and action reproduction, and they typically produce more actions after having observed positive as compared to negative emotional cues. This study explored infants' understanding of the referential specificity of others' emotional cues when being confronted with two actions that are accompanied by different emotional displays. Selective action reproduction was measured after 18-month-olds (N = 42) had observed two actions directed at the same object, one of which was modeled with a positive emotional expression and the other with a negative emotional expression. Across four trials with different objects, infants' first actions matched the positively-emoted actions more often than the negatively-emoted actions. In comparison with baseline-level, infants' initial performance changed only for the positively-emoted actions, in that it increased during test. Latencies to first object-touch during test did not differ when infants reproduced the positively- or negatively-emoted actions, respectively, indicating that infants related the cues to the respective actions rather than to the object. During demonstration, infants looked relatively longer at the object than at the model's face, with no difference in positive or negative displays. Infants during their second year of life thus capture the action-related referential specificity of others' emotional cues and seem to follow positive signals more readily when actively selecting which of two actions to reproduce preferentially.

Longitudinal Links between Executive Function, Anger, and Aggression in Middle Childhood. Front Behav Neurosci 2018; 12:27.

Abstract
Previous research has indicated that executive function (EF) is negatively associated with aggressive behavior in childhood. However, there is a lack of longitudinal studies that have examined the effect of deficits in EF on aggression over time and taken into account different forms and functions of aggression at the same time. Furthermore, only few studies have analyzed the role of underlying variables that may explain the association between EF and aggression. The present study examined the prospective paths between EF and different forms (physical and relational) and functions (reactive and proactive) of aggression. The habitual experience of anger was examined as a potential underlying mechanism of the link between EF and aggression, because the tendency to get angry easily has been found to be both a consequence of deficits in EF and a predictor of aggression. The study included 1,652 children (between 6 and 11 years old at the first time point), who were followed over three time points (T1, T2, and T3) covering 3 years. At T1, a latent factor of EF comprised measures of planning, rated via teacher reports, as well as inhibition, set shifting, and working-memory updating, assessed experimentally. Habitual anger experience was assessed via parent reports at T1 and T2. The forms and functions of aggression were measured via teacher reports at all three time points. Structural equation modeling revealed that EF at T1 predicted physical, relational, and reactive aggression at T3, but was unrelated to proactive aggression at T3. Furthermore, EF at T1 was indirectly linked to physical aggression at T3, mediated through habitual anger experience at T2. The results indicate that deficits in EF influence the later occurrence of aggression in middle childhood, and the tendency to get angry easily mediates this relation.

Abstract
Theory of mind is one of the most important cognitive factors in social information-processing, and deficits in theory of mind have been linked to aggressive behavior in childhood. The present longitudinal study investigated reciprocal links between theory of mind and two forms of aggression – physical and relational – in middle childhood with three data waves over 3 years. Theory of mind was assessed by participants’ responses to cartoons, and physical and relational aggression were assessed through teacher reports in a community sample of 1657 children (mean age at Time 1: 8 years). Structural equation modeling analyses showed that theory of mind was a negative predictor of subsequent physical and relational aggression, both from Time 1 to Time 2 as well as from Time 2 to Time 3. Moreover, relational aggression was a negative predictor of theory of mind from Time 1 to Time 2. There were no significant gender or age differences in the tested pathways. The results suggest that reciprocal and negative longitudinal relations exist between children’s theory of mind and aggressive behavior. Our study extends current knowledge about the development of such relations across middle childhood.

Longitudinal relations between children's cognitive and affective theory of mind with reactive and proactive aggression. Aggress Behav 2017; 43:440-449.

Abstract
Aggression may be performed for different reasons, such as defending oneself (reactive aggression) or to reach egoistic aims (proactive aggression). It is a widely accepted notion that a lack of theory of mind (ToM) as a basic social competence should be linked to higher aggression, but findings on the developmental links between ToM and different functions of aggression have been inconsistent. One reason for this may be the failure of taking the bi-dimensionality of both ToM (cognitive vs. affective) and aggression (reactive vs. proactive) into account. In addition, the direction of effect remains unclear because longitudinal studies examining the mutual influences of both constructs are rare. Because research on ToM has focused on the preschool years, little is known about its development in middle childhood. Therefore, the present study examined the bi-directional developmental links of cognitive and affective ToM with reactive and proactive aggression in a longitudinal study in N = 232, 6- to 9-year-olds. Two points of measurement with a delay of about 1 year were conducted, and data were analyzed via cross-lagged structural equation modeling (SEM), controlling for age, gender, and information processing. In general, early ToM predicted later functions of aggression, but not vice versa. Cognitive and affective ToM were inversely related to later reactive aggression, but only affective but not cognitive ToM was inversely related to later proactive aggression. These findings emphasize the importance of ToM for the occurrence of aggression and of taking the bi-dimensionality of both constructs into account when investigating their developmental links across childhood.

Abstract
The successful completion of the ESPRIT project CAMAS (EP 6756) and its extension to provide a link to the EURO PORT-1 action (EP 8421) (Mierendorff et al., 1995), together with further internal developments, has resulted in the availability of a portable message-passing version of the industrial crashworthiness program PAM-CRASH. This provides code users with an increased range of employment possibilities: effective use of resources through workstation networks, distributed-memory ma chines on which message passing is a necessity, and improved throughput on shared-memory or hybrid sys tems. With crash and safety analysis well established in the automotive design process, the availability of parallel application software enables the take-up of HPC technol ogy to the benefit of industrial design. In this paper, we illustrate the degree of scalability obtained for typical in dustrial applications and the challenges encountered on today's parallel machines.

Abstract
Positive objects or actions are associated with physical highness, whereas negative objects or actions are related to physical lowness. Previous research suggests that metaphorical connection (“good is up” or “bad is down”) between spatial experience and evaluation of objects is grounded in actual experience with the body. Prior studies investigated effects of spatial metaphors with respect to verticality of either static objects or self-performed actions. By presenting videos of object placements, the current three experiments combined vertically-located stimuli with observation of vertically-directed actions. As expected, participants’ ratings of emotionally-neutral objects were systematically influenced by the observed vertical positioning, that is, ratings were more positive for objects that were observed being placed up as compared to down. Moreover, effects were slightly more pronounced for “bad is down,” because only the observed downward, but not the upward, action led to different ratings as compared to a medium-positioned action. Last, some ratings were even affected by observing only the upward/downward action, without seeing the final vertical placement of the object. Thus, both, a combination of observing a vertically-directed action and seeing a vertically-located object, and observing a vertically-directed action alone, affected participants’ evaluation of emotional valence of the involved object. The present findings expand the relevance of spatial metaphors to action observation, thereby giving new impetus to embodied-cognition research.

Abstract
Intensive care unit (ICU) acquired or generalised weakness due to critical illness myopathy (CIM) and polyneuropathy (CIP) are major causes of chronically impaired motor function that can affect activities of daily living and quality of life. Physical rehabilitation of those affected might help to improve activities of daily living. Our primary objective was to assess the effects of physical rehabilitation therapies and interventions for people with CIP and CIM in improving activities of daily living such as walking, bathing, dressing and eating. Secondary objectives were to assess effects on muscle strength and quality of life, and to assess adverse effects of physical rehabilitation. On 16 July 2014 we searched the Cochrane Neuromuscular Disease Group Specialized Register and on 14 July 2014 we searched CENTRAL, MEDLINE, EMBASE and CINAHL Plus. In July 2014, we searched the Physiotherapy Evidence Database (PEDro) and three trials registries for ongoing trials and further data about included studies with no language restrictions. We also handsearched relevant conference proceedings and screened reference lists to identify further trials. We planned to include randomised controlled trials (RCTs), quasi-RCTs and randomised controlled cross-over trials of any rehabilitation intervention in people with acquired weakness syndrome due to CIP/CIM. We would have extracted data, assessed the risk of bias and classified the quality of evidence for outcomes in duplicate, according to the standard procedures of The Cochrane Collaboration. Outcome data collection would have been for activities of daily living (for example, mobility, walking, transfers and self care). Secondary outcomes included muscle strength, quality of life and adverse events. The search strategy retrieved 3587 references. After examination of titles and abstracts, we retrieved the full text of 24 potentially relevant studies. None of these studies met the inclusion criteria of our review. No data were suitable to be included in a meta-analysis. There are no published RCTs or quasi-RCTs that examine whether physical rehabilitation interventions improve activities of daily living for people with CIP and CIM. Large RCTs, which are feasible, need to be conducted to explore the role of physical rehabilitation interventions for people with CIP and CIM. This paper is based on a Cochrane Review published in in the Cochrane Database of Systematic Reviews (CDSR) 2015, Issue 3, DOI: 10.1002/14651858.CD010942.pub2. (see www.thecochranelibrary.com for information). Cochrane Reviews are regularly updated as new evidence emerges and in response to feedback, and the CDSR should be consulted for the most recent version of the review.

Abstract
There is robust evidence showing a link between executive function (EF) and theory of mind (ToM) in 3- to 5-year-olds. However, it is unclear whether this relationship extends to middle childhood. In addition, there has been much discussion about the nature of this relationship. Whereas some authors claim that ToM is needed for EF, others argue that ToM requires EF. To date, however, studies examining the longitudinal relationship between distinct subcomponents of EF [i.e., attention shifting, working memory (WM) updating, inhibition] and ToM in middle childhood are rare. The present study examined (1) the relationship between three EF subcomponents (attention shifting, WM updating, inhibition) and ToM in middle childhood, and (2) the longitudinal reciprocal relationships between the EF subcomponents and ToM across a 1-year period. EF and ToM measures were assessed experimentally in a sample of 1,657 children (aged 6–11 years) at time point one (t1) and 1 year later at time point two (t2). Results showed that the concurrent relationships between all three EF subcomponents and ToM pertained in middle childhood at t1 and t2, respectively, even when age, gender, and fluid intelligence were partialled out. Moreover, cross-lagged structural equation modeling (again, controlling for age, gender, and fluid intelligence, as well as for the earlier levels of the target variables), revealed partial support for the view that early ToM predicts later EF, but stronger evidence for the assumption that early EF predicts later ToM. The latter was found for attention shifting and WM updating, but not for inhibition. This reveals the importance of studying the exact interplay of ToM and EF across childhood development, especially with regard to different EF subcomponents. Most likely, understanding others’ mental states at different levels of perspective-taking requires specific EF subcomponents, suggesting developmental change in the relations between EF and ToM across childhood.

Abstract
Executive function (EF) has long been considered to be a unitary, domain-general cognitive ability. However, recent research suggests differentiating “hot” affective and “cool” cognitive aspects of EF. Yet, findings regarding this two-factor construct are still inconsistent. In particular, the development of this factor structure remains unclear and data on school-aged children is lacking. Furthermore, studies linking EF and overweight or obesity suggest that EF contributes to the regulation of eating behavior. So far, however, the links between EF and eating behavior have rarely been investigated in children and non-clinical populations. First, we examined whether EF can be divided into hot and cool factors or whether they actually correspond to a unitary construct in middle childhood. Second, we examined how hot and cool EF are associated with different eating styles that put children at risk of becoming overweight during development. Hot and cool EF were assessed experimentally in a non-clinical population of 1657 elementary-school children (aged 6–11 years). The “food approach” behavior was rated mainly via parent questionnaires. Findings indicate that hot EF is distinguishable from cool EF. However, only cool EF seems to represent a coherent functional entity, whereas hot EF does not seem to be a homogenous construct. This was true for a younger and an older subgroup of children. Furthermore, different EF components were correlated with eating styles, such as responsiveness to food, desire to drink, and restrained eating in girls but not in boys. This shows that lower levels of EF are not only seen in clinical populations of obese patients but are already associated with food approach styles in a normal population of elementary school-aged girls. Although the direction of effect still has to be clarified, results point to the possibility that EF constitutes a risk factor for eating styles contributing to the development of overweight in the long-term.
