Rilling JK, Richey L, Andari E, Hamann S. The neural correlates of paternal consoling behavior and frustration in response to infant crying. Dev Psychobiol 2021; 63:1370-1383.

Abstract
Human fathers often form strong attachments to their infants that contribute to positive developmental outcomes. However, fathers are also the most common perpetrators of infant abuse, and infant crying is a known trigger. Research on parental brain responses to infant crying have typically employed passive listening paradigms. However, parents usually engage with crying infants. Therefore, we examined the neural responses of 20 new fathers to infant cries both while passively listening, and while actively attempting to console the infant by selecting soothing strategies in a video game format. Compared with passive listening, active responding robustly activated brain regions involved in movement, empathy and approach motivation, and deactivated regions involved in stress and anxiety. Fathers reporting more frustration had less activation in basal forebrain areas and in brain areas involved with emotion regulation (e.g., prefrontal cortex and the supplementary motor area). Successful consolation of infant crying activated regions involved in both action-outcome learning and parental caregiving (anterior and posterior cingulate cortex). Overall, results suggest that active responding to infant cries amplifies activation in many brain areas typically activated during passive listening. Additionally, paternal frustration during active responding may involve a combination of low approach motivation and low engagement of emotion regulation.

Liel C, Meinck F, Steinert JI, Kindler H, Lang K, Eickhorst A. Is the Brief Child Abuse Potential Inventory (BCAPI) a valid measure of child abuse potential among mothers and fathers of young children in Germany? CHILD ABUSE & NEGLECT 2019; 88:432-444. [PMID: 30620919 DOI: 10.1016/j.chiabu.2018.11.008] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/03/2018] [Revised: 10/22/2018] [Accepted: 11/13/2018] [Indexed: 06/09/2023]
Abstract
BACKGROUND In order to prevent child abuse, instruments measuring child abuse potential (CAP) need to be appropriate, reliable and valid. OBJECTIVE This study aimed to confirm the 6-factor structure of the Brief Child Abuse Potential Inventory (BCAPI) in a German sample of mothers and fathers, and to examine longitudinal predictors of CAP. PARTICIPANTS AND SETTING Two waves of data were collected from 197 mothers and 191 fathers of children aged 10-21 months for the "Kinder in Deutschland - KiD 0-3" in-depth study. Families were stratified based on prior self-report data for screening purposes. METHODS 138 fathers and 147 mothers were included in the analysis (invalid: 25% mothers, 30% fathers). First, validity of reporting was examined. Second, confirmatory factor analysis (CFA) was employed to assess factor structure. Third, internal reliability and criterion validity were examined. Finally, multivariate poisson regressions investigated longitudinal predictors of CAP in mothers. RESULTS A previously established six-factor structure was confirmed for mothers but not fathers. CFA failed for fathers due to large numbers of variables with zero variance. For mothers, internal consistency and criterion validity were good. BCAPI score at follow-up was associated with baseline BCAPI score (β = 00.08), stress (β = 0.06), education (β=-0.19) and alcohol use (β = .58). CONCLUSIONS Findings confirm the six-factor structure of the BCAPI among German mothers. The clinical use of the BCAPI in fathers is not recommended as it might produce data that are hard to interpret. Further research with fathers is needed to establish if this is due to limitations with this dataset or with the questionnaire.

Abstract
Parents' exposure to stressful ecosocial situations, like inadequate resources, is linked to parents' perceptions of infants' fussing and crying and less sensitive caregiving. However, studies supporting these findings predominantly come from Western contexts of parenting and infant care. Ecosocial situations may have different effects on parenting and infants in distinct cultural contexts. In this study, the link between Gamo mothers' expressions of stress about their infants' negative emotional displays (N = 29 mothers and infants) and mother-infant interactions was investigated. Mothers who expressed stress in response to their infants' negative emotions demonstrated fewer interactions overall with their infants compared to mothers who did not express stress. Regression analyses showed that mothers who did not express stress had infants that fussed and cried more in their presence than infants of mothers who did not express stress, albeit insignificant. These results are discussed in the context of Gamo infancy in Southern Ethiopia.

Putting salient vocalizations in context: Adults' physiological arousal to emotive cues in domestic and external environments. Physiol Behav 2018; 196:25-32.

Abstract
Salient vocalizations are automatically processed and distinguished from emotionally irrelevant information. However, little is known of how contextual, gender and attentional variables interact to modulate physiological responses to salient emotive vocalizations. In this study, electrocardiogram (ECG) was utilized to investigate differences in peripheral nervous activity of men and women to infant cry (IC), infant laughter (IL) and adult cry (AC) in two different situational contexts: the domestic environment (DE) and the outside environment (OE). As the mental state of listeners can affect their response to vocalizations, a between-subject design was applied: one group was instructed to imagine being inside the scenes (Task 1: explicit task), and the other group was told to look at the scenes (Task 2: implicit task). Results revealed that females exhibited lower inter-beat interval (IBI) index in the OE condition, as compared to both males in OE and females in DE conditions, suggesting greater physiological arousal amongst females in response to vocalizations in an outside environment. Additionally, Task 1 revealed that males demonstrated higher Low Frequency/High Frequency (LFHF) index towards AC than IL. Task 2 showed the same association between these two sounds in females. The implicit task also elicited lower LFHF index in response to both IL and IC than control sound (CS), only amongst females. Findings highlight the important roles that contextual information and cognitive demand play in regulating physiological responses to salient emotive vocalizations. Integrated perspectives of physiological responses to emotive vocalizations that consider the influence of internal (adult mental states) and external (environment) contextual information will provide a better understanding of mechanisms underlying emotional processing of salient social cues.

Abstract
Emotional expressions are an essential element of human interactions. Recent work has increasingly recognized that emotional vocalizations can color and shape interactions between individuals. Here we present data on the psychometric properties of a recently developed database of authentic nonlinguistic emotional vocalizations from human adults and infants (the Oxford Vocal 'OxVoc' Sounds Database; Parsons, Young, Craske, Stein, & Kringelbach, 2014). In a large sample (n = 562), we demonstrate that adults can reliably categorize these sounds (as 'positive,' 'negative,' or 'sounds with no emotion'), and rate valence in these sounds consistently over time. In an extended sample (n = 945, including the initial n = 562), we also investigated a number of individual difference factors in relation to valence ratings of these vocalizations. Results demonstrated small but significant effects of (a) symptoms of depression and anxiety with more negative ratings of adult neutral vocalizations (R2 = .011 and R2 = .008, respectively) and (b) gender differences in perceived valence such that female listeners rated adult neutral vocalizations more positively and infant cry vocalizations more negatively than male listeners (R2 = .021, R2 = .010, respectively). Of note, we did not find evidence of negativity bias among other affective vocalizations or gender differences in perceived valence of adult laughter, adult cries, infant laughter, or infant neutral vocalizations. Together, these findings largely converge with factors previously shown to impact processing of emotional facial expressions, suggesting a modality-independent impact of depression, anxiety, and listener gender, particularly among vocalizations with more ambiguous valence.

Abstract
Adult appropriate responding to salient infant signals is vital to child healthy psychological development. Here we investigated how infant crying, relative to other emotive sounds of infant laughing or adult crying, captures adults' brain resources. In a sample of nulliparous women and men, we investigated the effects of different sounds on cerebral activation of the default mode network (DMN) and reaction times (RTs) while listeners engaged in self-referential decision and syllabic counting tasks, which, respectively, require the activation or deactivation of the DMN. Sounds affect women and men differently. In women, infant crying deactivated the DMN during the self-referential decision task; in men, female adult crying interfered with the DMN during the syllabic counting task. These findings point to different brain processes underlying responsiveness to crying in women and men and show that cerebral activation is modulated by situational contexts in which crying occurs.

Abstract
BACKGROUND Impaired social functioning is a well-established feature of depression. Evidence to date suggests that disrupted processing of emotional cues may constitute part of this impairment. Beyond processing of emotional cues, fluent social interactions require that people physically move in synchronized, contingent ways. Disruptions to physical movements are a diagnostic feature of depression (psychomotor disturbance) but have not previously been assessed in the context of social functioning. Here we investigated the impact of psychomotor disturbance in depression on physical responsive behavior in both an experimental and observational setting. METHODS In Experiment 1, we examined motor disturbance in depression in response to salient emotional sounds, using a laboratory-based effortful motor task. In Experiment 2, we explored whether psychomotor disturbance was apparent in real-life social interactions. Using mother-infant interactions as a model affective social situation, we compared physical behaviors of mothers with and without postnatal depression (PND). RESULTS We found impairments in precise, controlled psychomotor performance in adults with depression relative to healthy adults (Experiment 1). Despite this disruption, all adults showed enhanced performance following exposure to highly salient emotional cues (infant cries). Examining real-life interactions, we found differences in physical movements, namely reduced affective touching, in mothers with PND responding to their infants, compared to healthy mothers (Experiment 2). CONCLUSIONS Together, these findings suggest that psychomotor disturbance may be an important feature of depression that can impair social functioning. Future work investigating whether improvements in physical movement in depression could have a positive impact on social interactions would be of much interest.

Abstract
The current study tested the ability of whines and child-directed speech to attract the attention of listeners involved in a story repetition task. Twenty non-parents and 17 parents were presented with two dull stories, each playing to a separate ear, and asked to repeat one of the stories verbatim. The story that participants were instructed to ignore was interrupted occasionally with the reader whining and using child-directed speech. While repeating the passage, participants were monitored for Galvanic skin response, heart rate, and blood pressure. Based on 4 measures, participants tuned in more to whining, and to a lesser extent child-directed speech, than neutral speech segments that served as a control. Participants, regardless of gender or parental status, made more mistakes when presented with the whine or child-directed speech, they recalled hearing those vocalizations, they recognized more words from the whining segment than the neutral control segment, and they exhibited higher Galvanic skin response during the presence of whines and child-directed speech than neutral speech segments. Whines and child-directed speech appear to be integral members of a suite of vocalizations designed to get the attention of attachment partners by playing to an auditory sensitivity among humans. Whines in particular may serve the function of eliciting care at a time when caregivers switch from primarily mothers to greater care from other caregivers.

Abstract
OBJECTIVE Managing a crying infant is a challenge universally faced by new parents. This study examined whether parental interpretations, feelings, and behaviors following exposure to a 2-minute videotaped segment of a crying infant varied as a function of child physical abuse (CPA) risk and exposure to cues of hostility (i.e., hostile priming). METHOD Participants included 84 general population parents (52 low and 32 high CPA risk) with valid and complete protocols. It was predicted that (1) negative trait ratings, (2) feelings of hostility, and (3) ability to modulate grip strength would differ across CPA risk groups (high vs. low) and priming conditions (hostile vs. neutral). RESULTS As expected, high, compared to low, CPA risk parents rated the crying infant more negatively and reported higher levels of hostile feelings after watching the crying infant video. Hostile priming independently increased feelings of hostility, such that high CPA risk parents who were primed with hostile words reported higher levels of hostile feelings relative to all other conditions. Hostile priming also was modestly associated with increased use of excessive force when parents attempted to produce a half-strength grip; however this difference was apparent only among high CPA risk parents. CONCLUSIONS High, compared to low, CPA risk parents rated the crying infant more negatively and reported higher levels of hostile feelings after watching the crying infant video. Hostile priming independently increased hostile feelings and was modestly associated with use of excessive force in the hand grip task among high CPA risk parents.

Abstract
One of the functions of emotional vocalizations is the regulation of social relationships like those between adults and children. Listening to infant vocalizations is known to engage amygdala as well as anterior and posterior cingulate cortices. But, the functional relationships between these structures still need further clarification. Here, nonparental women and men listened to laughing and crying of preverbal infants and to vocalization-derived control stimuli, while performing a pure tone detection task during low-noise functional magnetic resonance imaging. Infant vocalizations elicited stronger activation in amygdala and anterior cingulate cortex (ACC) of women, whereas the alienated control stimuli elicited stronger activation in men. Independent of listeners' gender, auditory cortex (AC) and posterior cingulate cortex (PCC) were more strongly activated by the control stimuli than by infant laughing or crying. The gender-dependent correlates of neural activity in amygdala and ACC may reflect neural predispositions in women for responses to preverbal infant vocalizations, whereas the gender-independent similarity of activation patterns in PCC and AC may reflect more sensory-based and cognitive levels of neural processing. In comparison to our previous work on adult laughing and crying, the infant vocalizations elicited manifold higher amygdala activation.

Abstract
Existing research suggests that there may be benefits to teaching signing to hearing infants who have not yet developed vocal communication. In the current study, each of 4 infants ranging in age from 6 to 10 months was taught a simple sign using delayed prompting and reinforcement. In addition, Experiment 1 showed that 2 children independently signed in a variety of novel stimulus conditions (e.g., in a classroom, with father) after participating in sign training under controlled experimental conditions. In Experiment 2, crying and whining were replaced with signing when sign training was implemented in combination with extinction.

Abstract
Reduced hypothalamic-pituitary-adrenal (HPA) responses to stress during the last week of pregnancy and lactation have been consistently observed in rat studies. Several contributing factors have been proposed for this phenomenon in lactation, including the suckling stimulus from the pups, hormones (oxytocin and prolactin) and opioids, a decrease in the ability of noradrenaline to potentiate hypothalamic responses and changes in pituitary responsiveness to ACTH secretagogues (AVP and CRF). In contrast to this vast literature using the rat model, only few studies have addressed this issue in the human population. The consensus is that women engaging in breastfeeding activities exhibit reduced anxiety, although the reductions in neuroendocrine and autonomic responses to stressors are variable, in part because of the different nature of the stressors used. Further work is required to investigate how additional factors, such as maternal parity or emotional salience of the stressor can affect stress responsiveness in postpartum women. Here, we review first the findings regarding stress responsiveness during lactation in both rat and human studies, and then discuss potential research avenues and methodological issues that could be the lead to future research protocols in human subjects. Knowing the reciprocal relationship in the mother-infant dyad, it is clear that investigation of the mechanisms regulating stress responses and mental health in postpartum mothers can only be beneficial to the development of the infant.

Abstract
Theory and research suggest that spousal responses to displays of pain behavior can vary markedly. To our knowledge, observational research on spousal responses to pain behavior has been carried out only in chronic low back pain patients, but not in other populations. In this study systematic observations were conducted of interactions occurring between 50 married osteoarthritis patients (25 male and 25 female) and their respective spouses. Observations were conducted as the patient and spouse performed three common household tasks: sweeping the floor, folding laundry, and carrying small, artificial logs from one side of the room to the other. Contrary to prior research on chronic low back pain this study found that in osteoarthritis patients spouse facilitative behavior preceded and followed patient pain behavior significantly more often than did spouse solicitous behavior. A gender difference in spousal responding to pain behavior also was observed in that wives were significantly more likely to show facilitative behavior preceding and following patient pain behavior than were husbands. The implications of these findings for future research and clinical interventions focused on patient-spouse interactions are discussed.

Abstract
The proximate causes, survival value, ontogeny, and evolutionary history of human infant crying are examined. Experiments and field observations involving infant distress vocalizations and begging calls in avian, mammalian, and nonhuman primate species are considered, as are ethnographic records of infant care and responses to crying in nonindustrialized societies. It is argued that human infant crying evolved as a primarily acoustic, graded signal, that it is a fairly reliable, if imperfect, indicator of need for parental care and that its primary function is to promote parental caregiving. Selection pressures that may have shaped the evolution of crying and its potential for corruption through dishonesty also are discussed.

Abstract
In this longitudinal investigation, Bell and Ainsworth's (1972) Baltimore study on maternal responsiveness, infant crying and infant attachment security was replicated and extended. Each of the 50 families was observed at home during more than 20 hours, and infant crying behavior as well as maternal responses were recorded. Mothers and their infants were observed in the Strange Situation procedure at 15 months of age. Descriptive results showed that infants produced about the same number of crying bouts across the first 40 weeks after birth, but the duration of the bouts decreased by half during this period. The duration of crying peaked in the first nine weeks. The descriptive data are remarkably similar to the findings of Bell and Ainsworth (1972). Maternal responsiveness influenced crying behavior. Contrary to our expectations, the more frequently mothers ignored their infants' crying bout in the first nine-week period, the less frequently their infants cried in the following nine-week period, even if intervening variables like earlier crying and synchronous responsiveness were controlled for. 'Benign neglect' of fussing may stimulate the emergent abilities in infants to cope with mild distress. Extending an earlier report on this investigation (Hubbard & van IJzendoorn, 1991), we found that crying at home did not differentiate between secure and insecure attachment classifications, and it was not related to Strange Situation crying. Mothers of avoidant infants responded most promptly to their infants' crying. The failure to replicate the Baltimore findings was interpreted in terms of 'differential responsiveness'.

Abstract
OBJECTIVE Several components of a social information processing model of child physical abuse were tested. Abusive and comparison mothers' evaluations of children's transgressions, choices of disciplinary techniques, expectations for children's compliance following discipline, and appraisals of the appropriateness of disciplinary choice were examined in a no-cry and a crying-infant condition. METHOD Thirty physically abusive and 30 matched comparison mothers were individually matched on ethnic background, age, education, marital status, number of children, and cognitive ability. Mothers were asked to respond to questions related to vignettes describing children engaging in moral, conventional, and personal transgressions. RESULTS As predicted, abusive, relative to comparison, mothers evaluated conventional and personal, but not moral, transgressions as more wrong, used more power assertion (physical and verbal force), expected less compliance from their own children, and appraised their own disciplinary responses as less appropriate. In contrast to expectations, there were no group by cry condition interaction effects on any of the study measures. CONCLUSIONS The findings provide additional support for the view that abusive, relative to comparison, mothers are different in their evaluations and expectations of their own children's behaviors and that they more frequently select aversive disciplinary techniques. However, given the lack of an expected differential impact of a stressful condition on the cognitions and disciplinary choices in abusive mothers, additional research is needed.
