Abstract
Objective: This article systematically reviews the effects of technology-based (TB) treatments on impaired social cognition (SC) in neurological and mental disorders. Methods: Strictly adhering to the PRISMA guidelines, a systematic search was carried out in PsycINFO, PubMed, and Web of Science (last search: April 22, 2021) to identify studies that, implementing a control group design, evaluated TB treatments targeting deficits in emotion recognition, Theory of Mind (ToM) and social behavior in adult patients with nondevelopmental and nonprogressive neurological or mental disorders. Risk of bias was assessed using the PEDro Scale, certainty assessment followed the GRADE approach. Results: Sixteen studies involving 857 patients, all focusing on psychotic disorders, were retrieved. The most pronounced effects were observed concerning emotion recognition with all studies revealing overall improvements. Regarding ToM and social behavior, results were mixed. However, the number of studies including outcome measures for these domains, is significantly lower compared to the domain of emotion recognition, limiting the validity of the results. Risk of bias and certainty assessment revealed further limitations of evidence. Conclusion: TB treatment achieves positive effects especially with regard to emotion recognition impairments, at least for patients with schizophrenia. Future research should expand the evaluation of TB training of other SC domains, ought to be carried out in more diverse patient populations, rely on different devices, and include follow-up measurements.

Abstract
OBJECTIVES To assess the usefulness of a computerized tasks module designed for the rehabilitation of social cognition (SC) in acquired brain injury. METHODS Quasi-randomized controlled trial (ClinicalTrials.gov:NCT03479970) involving 45 patients with moderate-severe traumatic brain injury (TBI) in a subacute inpatient rehabilitation hospital. The experimental group (n = 28) received treatment with a computerized SC module in combination with a non-SC module. The control group (n = 26) only received a treatment with non-SC module. RESULTS Intragroup comparisons showed that the experimental group had better results for all SC measures, except for International Affective Picture System (IAPS). The control group improved for Facial Expressions of cEmotion-Stimuli and Tests (FEEST) and Moving Shapes Paradigm (MSP), showing no changes with respect to pretreatment in IAPS, MSP and Reading the Mind in the Eyes Test (RMET). Intergroup comparisons did not present differences between the two groups for pretreatment measures. Post-treatment comparison showed that the experimental group obtained better results for RMET than the control group. CONCLUSION The computerized SC module was useful for the rehabilitation of SC in patients with moderate-severe TBI in the subacute phase. The group that received combined rehabilitative treatment (SC + non-SC) obtained better results for SC than the group that received treatment intended only for non-SC.

Theory of mind and facial emotion recognition in adults with temporal lobe epilepsy: A meta-analysis. Front Psychiatry 2022; 13:976439.

Abstract
BACKGROUND Mounting studies have investigated impairments in social cognitive domains (including theory of mind [ToM] and facial emotion recognition [FER] in adult patients with temporal lobe epilepsy (TLE). However, to date, inconsistent findings remain. METHODS A search of PubMed, Web of Science, and Embase databases was conducted until December 2021. Hedges g effect sizes were computed with a random-effects model. Meta-regressions were used to assess the potential confounding factors of between-study variability in effect sizes. RESULTS The meta-analysis included 41 studies, with a combined sample of 1,749 adult patients with TLE and 1,324 healthy controls (HCs). Relative to HCs, adult patients with TLE showed large impairments in ToM (g = -0.92) and cognitive ToM (g = -0.92), followed by medium impairments in affective ToM (g = -0.79) and FER (g = -0.77). Besides, no (statistically) significant differences were observed between the magnitude of social cognition impairment in adult with TLE who underwent and those who did not undergo epilepsy surgery. Meta-regressions exhibited that greater severity of executive functioning was associated with more severe ToM defects, and older age was associated with more severe FER defects. CONCLUSIONS Results of this meta-analysis suggest that adult patients with TLE show differential impairments in the core aspects of social cognitive domains (including ToM and FER), which may help in planning individualized treatment with appropriate cognitive and behavioral interventions.

Abstract
Studies of abnormal theory of mind (ToM) performance in adult patients with traumatic brain injury (TBI) have reported inconsistent results. Therefore, we conducted a meta-analysis to characterize ToM performance in adult patients with TBI. Random-effects models were employed to estimate the overall effect size and the differential effect sizes across different ToM aspects. Based on a sample of 28 studies (1031 patients and 865 healthy controls), the meta-analytic findings revealed that ToM was significantly impaired in adult patients with TBI compared to healthy controls (g = -1.13). Besides, patients with TBI showed significant impairments in individual ToM tasks, as well as for different stimulus modes and contents involved in these ToM tasks. A meta-regression indicated a positive association between ToM performance and Glasgow Coma Scale score. The results of the current meta-analysis suggest that the performance in ToM tasks may be a good predictor of functional outcomes in adults with TBI, which is important for the identification of targets for cognitive interventions and the development of useful training intervention programs.

Abstract
Twenty-two adult participants, assigned to three conditions, were trained nutrition knowledge (i.e., carbohydrate values) for different food items. In a stimulus sorting test, the participants were asked to sort stimuli (names of food items) into one of three different ranges of carbohydrate values ("less than 20", "20–40", "more than 40" gram per 100 gram). Conditional-discrimination training and testing followed the sorting test, and finally, a postclass formation sorting test of the stimuli used in the conditional-discrimination training. The conditional-discrimination training used tailored stimuli, that is, the food items that each of the participants categorized incorrectly in the sorting test. Participants exposed to Conditions 1 and 2 were trained on six conditional discriminations and tested for the formation of three 3-member classes. Conditions 2 and 3 had a “don’t know” option together with the three different ranges of carbohydrate values in the sorting for tailoring the stimuli. Participants exposed to Condition 3 trained were trained on 12 conditional discriminations and tested for the formation of three 5-member classes. The main findings showed that all but one of the participants responded correctly on at least one test for equivalence class formation and sorted the stimuli correctly in the postclass formation sorting test.

Abstract
Social cognition (SC) consists of mental representations of interpersonal relationships, which are used flexibly by the individual to promote functional social behaviors and achieve the goals. SC is a multidimensional construct and is supported by the activity of distributed neural networks in which different cortical and subcortical regions of the brain are involved. The review aims to evaluate the current literature on SC taking into account how it is compromised in acquired brain injury. Studies performed between 2010 and 2019 and fulfilling the selected criteria were searched on PubMed, Scopus, Cochrane and Web of Sciences databases. Impairment of SC is a neglected but common consequence of ABI, often leading to disordered interpersonal functioning and poor regulation of personal behavior with impaired social adaptation and quality of life of both the patient and his/her family. This review supports the idea that SC could have an important role in the management of neurological patients by both clinicians and caregivers.

Abstract
A single case design (AB with follow up) was used to determine the effect of a combined visual scanning and verbal cuing intervention technique in improving facial affect recognition after traumatic brain injury (TBI). A 35-year-old male (BR) with impaired ability to recognize facial emotions as a result of severe TBI participated in the study over a 3-month duration. BR's mean accuracy across six universal static facial expressions of emotion improved significantly during intervention and was maintained at follow up. BR was most impaired in labelling negative (sad, angry, disgusted, anxious) versus positive facial expressions (surprised, happy). BR's accuracy to negative facial affect significantly improved during intervention. No further improvement was possible for positive expressions because a ceiling effect was observed at baseline. Overall BR's mean response times across emotions was reduced at baseline but increased significantly during intervention. This was also recorded for both positive and negative expressions, respectively. This novel combined intervention has potential to improve facial affect recognition after TBI. Further evaluation using a multiple-baseline design is recommended. Additional research is needed to determine whether improved facial affect recognition following training translates to improvements in social function and communication in people with TBI.

Abstract
BACKGROUND Many patients with moderate to severe traumatic brain injury have deficits in social cognition. Social cognition refers to the ability to perceive, interpret, and act upon social information. Few studies have investigated the effectiveness of treatment for impairments of social cognition in patients with traumatic brain injury. Moreover, these studies have targeted only a single aspect of the problem. They all reported improvements, but evidence for transfer of learned skills to daily life was scarce. We evaluated a multifaceted treatment protocol for poor social cognition and emotion regulation impairments (called T-ScEmo) in patients with traumatic brain injury and found evidence for transfer to participation and quality of life. PURPOSE In the current paper, we describe the theoretical underpinning, the design, and the content of our treatment of social cognition and emotion regulation (T-ScEmo). THEORY INTO PRACTICE The multifaceted treatment that we describe is aimed at improving social cognition, regulation of social behavior and participation in everyday life. Some of the methods taught were already evidence-based and derived from existing studies. They were combined, modified, or extended with newly developed material. PROTOCOL DESIGN T-ScEmo consists of 20 one-hour individual sessions and incorporates three modules: (1) emotion perception, (2) perspective taking and theory of mind, and (3) regulation of social behavior. It includes goal-setting, psycho-education, function training, compensatory strategy training, self-monitoring, role-play with participation of a significant other, and homework assignments. RECOMMENDATIONS It is strongly recommended to offer all three modules, as they build upon each other. However, therapists can vary the time spent per module, in line with the patients' individual needs and goals. In future, development of e-learning modules and virtual reality sessions might shorten the treatment.

Rehabilitation of social cognition impairment after traumatic brain injury: A systematic review. Neurologia 2018; 37:S0213-4853(18)30202-0.

Abstract
INTRODUCTION Many studies have described the presence of difficulty processing and generating social behaviour in patients who have suffered a traumatic brain injury (TBI). These difficulties in social cognition (SC) deteriorate personal relationships in the family, at work, or in the community. However, therapeutic programmes aiming to improve SC continue to be an outstanding issue in clinical practice. We performed a systematic review of the existing literature on the recovery of SC in patients with TBI, assessing the methodological quality of the included studies and the therapeutic effectiveness of the rehabilitation strategies used. DEVELOPMENT We performed a bibliographic search of papers published before June 2018 in the Medline/PubMed, Google Scholar, PsycINFO, and ClinicalTrials.gov databases. Of the 198 potentially relevant articles, 10 met our eligibility criteria. Two of the authors independently and blindly assessed the methodological quality of these studies using the PEDro scale. CONCLUSIONS The articles included in this systematic review essentially studied the effect of different interventions aimed at the rehabilitation of SC in patients with chronic TBIs. The analysis showed adequate methodological quality and an acceptable level of evidence. Future research should analyse the effect of these interventions in patients with TBIs in the sub- and post-acute phases.

Abstract
Objective: The aim of this study is to review published research on treatment of social cognition impairments in patients with traumatic brain injury (TBI).Methods: Following the PRISMA guidelines, a PubMed literature search was conducted, followed by a manual search in recently published papers. Main criteria for selection were that patients had sustained a TBI, and that social cognition was the main target of treatment. A total of 16 papers and three reviews were selected and included in the present review.Results: Five studies (including three randomized controlled trials (RCT)) addressed facial affect recognition, one study specifically addressed emotional prosody, two RCTs used a combination of treatment strategies addressing social perception deficits. Six studies, including two RCTs, addressed social communication skills or theory of mind. Finally, two RCTs reported the effectiveness of a more global approach, addressing multiple domains of social cognition, such as emotion perception, social skills training, and theory of mind.Discussion/conclusion: Although there has been much less research on treatment of social cognition in patients with TBI as compared with psychiatric conditions, the findings reported in the present review are encouraging. Further multicenter large-scale RCTs are needed, with special emphasis on the generalization of treatment effects to social skills in everyday life.

Abstract
Neuropsychological assessments of cognitive dysfunction in cerebrovascular illness commonly target basic cognitive functions involving aspects of memory, attention, language, praxis, and number processing. Here, I highlight the clinical importance of often-neglected social cognition functions. These functions recruit a widely distributed neural network, making them vulnerable in most cerebrovascular diseases. Sociocognitive deficits underlie most of the problematic social conduct observed in patients and are associated with more negative clinical outcomes (compared to nonsocial cognitive deficits). In clinical settings, social cognition deficits are normally gleaned from collateral information from caregivers or from indirect inferences made from patients' performance on standard nonsocial cognitive tests. Information from these sources is however inadequate. I discuss key social cognition functions, focusing initially on deficits in emotion perception and theory of mind, two areas that have gained sizeable attention in neuroscientific research, and then extend the discussion into relatively new, less covered but crucial functions involving empathic behaviour, social awareness, social judgements, and social decision making. These functions are frequently impaired following neurological change. At present, a wide range of psychometrically robust social cognition tests is available, and this review also makes the case for their inclusion in neuropsychological assessments.

Abstract
Objectives: This study examined the current assessment practices of clinicians working with people with social cognition impairment following traumatic brain injury.Method: Two hundred and sixty clinicians completed an on-line survey that was disseminated through professional brain injury organisations. Of respondents around 90% were allied health clinicians, with the remainder comprising medical, nursing and academia.Main outcomes: The four areas of social cognition that were routinely assessed across the disciplines were insight, disinhibition, anger and social adjustment. The least routinely assessed areas were theory of mind and alexithymia. The test suggested most likely to identify social cognition impairments was The Awareness of Social Inference Test, although only 8% of clinicians responded to this question. Clinicians preferred informal assessment methods over standardised assessment methods for identifying social cognition rehabilitation goals. Higher levels of education were associated with greater use of standardised assessment modalities. Whilst there was paucity of responses overall, TBI Express was most commonly used for social cognition rehabilitation.Conclusions: Considering the high prevalence of social cognition impairments in this population, formal assessment is extremely limited. The under-utilisation of assessment tools is problematic for the assessment and rehabilitation initiatives offered to people with TBI. These results have implications for the training of clinicians working in brain injury rehabilitation.

Abstract
This article provides an overview of interventions developed and trialled in the embryonic field of social cognition neuro-rehabilitation. Interventions are categories under the headings of explicit skills training, embodied/relational interventions, and relational approaches. The assessment and treatment of social neuropsychological impairments have received comparably less attention and development than other domains of cognition. These include difficulties in representing the intentions and perspectives of others (mentalising), recognising emotions, inferring nuanced social communications such as sarcasm and deceit, accessing social knowledge, and emotion-based decision-making. Founded on distributed neuroanatomical substrates, impairments of these functions have been found to be present and enduring across major sub-groups of acquired brain injury (for review see [1]). The theoretical richness of the social neuroscience revolution has not been matched by the translation of concepts and findings into rehabilitation practice. This article will review the embryonic field of social cognition rehabilitation, categorised into three intervention clusters: a) explicit skills training, b) embodied and affective interventions and c) relational approaches.

Abstract
Instructional designers plan current student experiences that promote future competence. There is a wide agreement that current instruction should allow students to “go beyond the information given” by demonstrating novel understanding. Less clear is what instructional efforts yield what specific emergent knowledge. Under these conditions, emergent learning remains an untestable, and therefore unscientific, concept. We describe a framework that creates emergent learning in both novice and experienced learners, and in many academic subjects, specifying preconditions that will yield specific emergent learning outcomes, and thereby promoting a desirable level of prospective precision in the planning of future student competence.

Abstract
Instructors of the visually impaired need efficient braille-training methods. This study conducted a preliminary evaluation of a computer-based program intended to teach the relation between braille characters and English letters using a matching-to-sample format with 4 sighted college students. Each participant mastered matching visual depictions of the braille alphabet to their printed-word counterparts. Further, each participant increased the number of words they read in a braille passage following this training. These gains were maintained at variable levels on a maintenance probe conducted 2 to 4 weeks after training.

Effects of computerized match-to-sample training on emergent fraction-decimal relations in individuals with fragile X syndrome. RESEARCH IN DEVELOPMENTAL DISABILITIES 2012; 33:1-11.

Abstract
Individuals diagnosed with fragile X syndrome (FXS), the most common known form of inherited intellectual disability, are reported to exhibit considerable deficits in mathematical skills that are often attributed to brain-based abnormalities associated with the syndrome. We examined whether participants with FXS would display emergent fraction-decimal relations following brief, intensive match-to-sample training on baseline relations. The performance profiles on tests of symmetry and transitivity/equivalence of 11 participants with FXS, aged 10-23 years, following baseline match-to-sample training were compared to those of 11 age- and IQ-matched controls with idiopathic developmental disability. The results showed that both groups of participants showed significant improvements in the baseline (trained) relations, as expected. However, participants with FXS failed to show significant improvements in the (untrained) symmetry and transitivity/equivalence relations compared to those in the control group. A categorical analysis of the data indicated that five participants with FXS and eight controls showed at least "intermediate" emergence of symmetry relations, whereas one individual with FXS and three controls showed at least intermediate emergence of transitivity/equivalence relations. A correlation analysis of the data indicated that improvements in the symmetry relations were significantly associated with improvements in the transitivity/equivalence relations in the control group (r=.69, p=.018), but this was not the case in the FXS group (r=.34, p>.05). Participant IQ was significantly associated with improvements in the symmetry relations in individuals with FXS (r=.60, p=.049), but not in controls (r=.21, p>.05). Taken together, these results suggest that brief, computerized match-to-sample training may produce emergent mathematical relations for a subset of children with FXS and developmental disabilities. However, the ability of individuals with FXS to form transitivity/equivalence relations may be impaired relative to those with idiopathic developmental disabilities, which may be attributed to neurodevelopmental variables associated with the syndrome.

Modifying emotion recognition deficits in body dysmorphic disorder: an experimental investigation. Depress Anxiety 2011; 28:924-31.

Abstract
BACKGROUND Individuals with body dysmorphic disorder (BDD) are characterized by excessive concerns about perceived defects or flaws in their appearance, most commonly, facial features. Previous research has shown that BDD sufferers, relative to mentally healthy controls, are characterized by emotion recognition deficits (particularly a bias to misinterpret neutral facial expressions in a negative way). It remains an open question though whether these deficits can be modified through specific training programs. METHODS To address this question, we evaluated emotion recognition among individuals with BDD (n = 34), individuals with a dermatological condition (n = 34), and mentally healthy control participants (n = 34) before and after a single-session emotion recognition training program. RESULTS As expected, BDD participants were overall significantly worse in identifying neutral expressions, relative to the other groups, whereas no difference was obtained between the dermatology and control groups. Further, with respect to neutral and scared expressions, BDD participants improved significantly more in the training condition, relative to the nontraining condition. CONCLUSION There is initial evidence that deficits in recognizing neutral and scared expressions can be normalized through a specific training program when evaluated immediately after the training session. It needs to be addressed in future research whether emotion recognition training programs can diminish these deficits on the long term, and how improved emotion recognition might be related to BDD's symptom reduction such as decreased avoidance behaviors in social situations.

Abstract
Social functioning deficits are a prominent feature of many neurological and psychiatric conditions, and may include disruption in the acquisition or application of basic or complex social skills. Such disturbances are often resistant to treatment, and individuals with such conditions are often faced with lifelong difficulties in maintaining personal relationships, employment, and independent living. In recent years, a number of psychosocial treatments have been developed to address this growing problem. In this article, we review studies investigating the use of psychosocial training interventions in individuals with acquired brain injuries, which frequently require intervention for impairments in cognitive and social functioning. We then discuss limitations of these studies and highlight specific areas in which such treatments might be improved in the future.

Equivalence class formation: a method for teaching statistical interactions. J Appl Behav Anal 2010; 42:575-93. [PMID: 20190920 DOI: 10.1901/jaba.2009.42-575] [Citation(s) in RCA: 56] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2008] [Accepted: 06/18/2008] [Indexed: 11/22/2022]
Abstract
Many students struggle with statistical concepts such as interaction. In an experimental group, participants took a paper-and-pencil test and then were given training to establish equivalent classes containing four different statistical interactions. All participants formed the equivalence classes and showed maintenance when probes contained novel negative exemplars. Thereafter, participants took a second paper-and-pencil test. Participants in the control group received two versions of the paper-and-pencil test without equivalence-based instruction. All participants in the experimental group showed increased paper-and-pencil test scores after forming the interaction-indicative equivalence classes. Class-indicative responding also generalized to novel exemplars and the novel question format used in the paper-and-pencil test. Test scores did not change with repetition for control group participants. Implications for behavioral diagnostics and teaching technology are discussed.

Abstract
PRIMARY OBJECTIVE To review the literature of affect recognition for persons with traumatic brain injury (TBI). It is suggested that impairment of affect recognition could be a significant problem for the TBI population and treatment strategies are recommended based on research for persons with autism. MAIN OUTCOMES AND RESULTS Research demonstrates that persons with TBI often have difficulty determining emotion from facial expressions. Studies show that poor interpersonal skills, which are associated with impaired affect recognition, are linked to a variety of negative outcomes. Theories suggest that facial affect recognition is achieved by interpreting important facial features and processing one's own emotions. These skills are often affected by TBI, depending on the areas damaged. Affect recognition impairments have also been identified in persons with autism. Successful interventions have already been developed for the autism population. Comparable neuroanatomical and behavioural findings between TBI and autism suggest that treatment approaches for autism may also benefit those with TBI. CONCLUSIONS Impaired facial affect recognition appears to be a significant problem for persons with TBI. Theories of affect recognition, strategies used in autism and teaching techniques commonly used in TBI need to be considered when developing treatments to improve affect recognition in persons with brain injury.

The importance of vocal affect to bimodal processing of emotion: implications for individuals with traumatic brain injury. JOURNAL OF COMMUNICATION DISORDERS 2009; 42:1-17.

Abstract
UNLABELLED Persons with traumatic brain injury (TBI) often have difficulty recognizing emotion in others. This is likely due to difficulties in interpreting non-verbal cues of affect. Although deficits in interpreting facial cues of affect are being widely explored, interpretation of vocal cues of affect has received much less attention. Accurate interpretation of vocal affect cues is important, particularly when facial cues are absent or ambiguous. These cues also contribute to more accurate identification of emotion. The neural substrates of facial and vocal affect recognition appear to be shared, further contributing to improved bimodal processing. This article discusses the importance of vocal affect cues in interpreting emotion. Expression of vocal affect in persons with TBI is also briefly discussed since difficulty in controlling and manipulating vocal cues of emotion when speaking may also contribute to poor social outcomes. A review of the literature in acoustic parameters that contribute to identification and expression of emotions is followed by a discussion on the integration of visual and auditory cues in bimodal processing and the relationship between facial and vocal affect in persons with TBI. LEARNING OUTCOMES Readers will be able to: 1) Identify the parameters primarily used to describe the acoustic characteristics of vocal affect; 2) Describe the acoustic parameters typically associated with Anger, Fear, Happiness and Sadness; 3) Describe the difficulties experienced by persons with TBI in the perception and integration of facial and vocal cues of affect.

Conditional associative learning examined in a paralyzed patient with amyotrophic lateral sclerosis using brain-computer interface technology. Behav Brain Funct 2008; 4:53. [PMID: 19025641 PMCID: PMC2599893 DOI: 10.1186/1744-9081-4-53] [Citation(s) in RCA: 13] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2008] [Accepted: 11/24/2008] [Indexed: 12/13/2022] Open
Abstract
Background Brain-computer interface methodology based on self-regulation of slow-cortical potentials (SCPs) of the EEG (electroencephalogram) was used to assess conditional associative learning in one severely paralyzed, late-stage ALS patient. After having been taught arbitrary stimulus relations, he was evaluated for formation of equivalence classes among the trained stimuli. Methods A monitor presented visual information in two targets. The method of teaching was matching to sample. Three types of stimuli were presented: signs (A), colored disks (B), and geometrical shapes (C). The sample was one type, and the choice was between two stimuli from another type. The patient used his SCP to steer a cursor to one of the targets. A smiley was presented as a reward when he hit the correct target. The patient was taught A-B and B-C (sample – comparison) matching with three stimuli of each type. Tests for stimulus equivalence involved the untaught B-A, C-B, A-C, and C-A relations. An additional test was discrimination between all three stimuli of one equivalence class presented together versus three unrelated stimuli. The patient also had sessions with identity matching using the same stimuli. Results The patient showed high accuracy, close to 100%, on identity matching and could therefore discriminate the stimuli and control the cursor correctly. Acquisition of A-B matching took 11 sessions (of 70 trials each) and had to be broken into simpler units before he could learn it. Acquisition of B-C matching took two sessions. The patient passed all equivalence class tests at 90% or higher. Conclusion The patient may have had a deficit in acquisition of the first conditional association of signs and colored disks. In contrast, the patient showed clear evidence that A-B and B-C training had resulted in formation of equivalence classes. The brain-computer interface technology combined with the matching to sample method is a useful way to assess various cognitive abilities of severely paralyzed patients, who are without reliable motor control.
