Facial affect recognition in context in adults with and without TBI.

Several studies have reported impaired emotion recognition in adults with traumatic brain injury (TBI), but studies have two major design features that limit application of results to real-world contexts: (1) participants choose from among lists of basic emotions, rather than generating emotion labels, and (2) images are typically presented in isolation rather than in context. To address these limitations, we created an open-labeling task with faces shown alone or in real-life scenes, to more closely approximate how adults with TBI label facial emotions beyond the lab. Participants were 55 adults (29 female) with moderate to severe TBI and 55 uninjured comparison peers, individually matched for race, sex, and age. Participants viewed 60 photographs of faces, either alone or in the pictured person's real-life context, and were asked what that person was feeling. We calculated the percent of responses that were standard forced-choice-task options, and also used sentiment intensity analysis to compare verbal responses between the two groups. We tracked eye movements for a subset of participants, to explore whether gaze duration or number of fixations helped explain any group differences in labels. Over 50% of responses in both groups were words other than basic emotions on standard affect tasks, highlighting the importance of eliciting open-ended responses. Valence of labels by participants with TBI was attenuated relative to valence of Comparison group labels, i.e., TBI group responses were less positive to positive images and the same was true for negative images, although the TBI group responses had higher lexical diversity. There were no significant differences in gaze duration or number of fixations between groups. Results revealed qualitative differences in affect labels between adults with and without TBI that would not have emerged on standard forced-choice tasks. Verbal differences did not appear to be attributable to differences in gaze patterns, leaving open the question of mechanisms of atypical affect processing in adults with TBI.

Measuring LEND Core Competencies Using Trainee Follow-Up Surveys.

Measuring the value-added impact of Leadership Education in Neurodevelopmental Disabilities and Related Disorders (LEND) training on trainees' leadership and career trajectories is necessary to understand program efficacy. In the current study, we leveraged an existing ex post facto design to develop and test a new measure of LEND competencies and compare outcomes of LEND trainees and comparison peers. We developed the LEND Outcomes Follow-Up Survey using a multi-step, mixed methods process. A series of focus groups and consultations with key stakeholders identified eight important LEND leadership outcomes: (1) interdisciplinary work; (2) advocacy; (3) intersectional approach; (4) systems perspective; (5) life course perspective; (6) leadership; (7) engagement with maternal and child health populations; and (8) research experience. We developed and piloted this novel survey to measure these LEND leadership outcomes. We used data collected from this novel measure and an existing survey that is used nationally by LEND, to compare the outcomes of 43 LEND trainees and 30 comparison peers at two years post completion of LEND training. We found that, compared to comparison peers, LEND trainees: (1) worked with a greater number of disciplines; (2) were more likely to be engaged in advocacy; (3) were more likely to utilize a systems perspective in their work; (4) were more likely to work with maternal and child health populations; and (5) were more likely to have experience conducting research. Our findings suggested that LEND training improves LEND leadership outcomes at two years post-completion of LEND training.

Attachment and general well-being in breast cancer patients: Mediation of body esteem and social support

This study aimed to explore the mediation of body esteem and social support in the relationship between attachment and general well-being in breast cancer patients. We collected data from 150 women with breast cancer and 150 healthy women. Employing bootstrap analysis with 5 000 samples using the ordinary least squares regression, we found that higher attachment avoidance was significantly associated with lower general well-being in both the breast cancer patients and healthy comparison peers. Also, body esteem and social support were significantly associated with attachment anxiety and attachment avoidance and general well-being. Furthermore, body esteem significantly mediated the relationship between attachment avoidance and well-being in breast cancer patients directly through social support; while social support significantly mediated the relationship between attachment anxiety and attachment avoidance and well-being in breast cancer women directly by body esteem. Therefore, body esteem and social support played a chain intermediary role between attachment avoidance and well-being. These findings suggest a need for breast cancer support programmes for women to enhance their body esteem and sense of social support in the context of their recovery efforts.

Emotional Well-Being of Pediatric Brain Tumor Survivors and Comparison Peers: Perspectives From Children and Their Parents.

The aim of this study was to examine the emotional well-being of pediatric brain tumor survivors (PBTS) from the perspective of children's self-reports and parents' reports relative to matched comparison peers (COMP) and their parents. It was hypothesized that PBTS would self-report more depression symptoms, loneliness, and lower self-concept than COMP. We also hypothesized that mothers and fathers of PBTS would report more internalizing symptoms and lower total competence for their children. Age and sex effects were examined in exploratory analyses. Families of 187 PBTS and 186 COMP participated across 5 sites. Eligible children in the PBTS group were 8-15 years of age and 1-5 years post-treatment for a primary intracranial tumor without progressive disease. COMP were classmates matched for sex, race, and age. PBTS self-reported lower scholastic, athletic, and social competence, but not more depression, loneliness, or lower global self-worth than COMP. Parents of PBTS reported more internalizing symptoms and lower total competence than parents of COMP. With few exceptions, group differences did not vary as a function of child age and sex. PBTS reported diminished self-concept in scholastic, athletic, and social domains, while their parents reported broader challenges with internalizing symptoms and total competence. Discrepancies between self-report and parent report require further study to inform targeted interventions for PBTS. Screening survivors for emotional challenges in follow-up clinic or in school setting may help with the allocation of psychosocial support and services for PBTS and their families.

Examining the effects of quality talk discussions on 4th- and 5th-grade students’ high-level comprehension of text

Given the rapid pace of technological change, access to unlimited information, and diverse forms of complex text, the importance and demand for enhanced literacy skills is greater than ever. Accordingly, researchers have begun developing integrated, multifaceted interventions that dynamically support enhanced literacy competence. The purpose of this year-long quasi-experimental study was to compare the effects of a multifaceted, rigorous discussion intensive literacy intervention called Quality Talk (QT) to a comparison intervention. Fourth- and fifth-grade students (QT treatment, n = 133; comparison, n = 155) from two public schools participated in a district-wide literacy program with half also participating in QT within their language arts class. Spanning baseline and two subsequent time points, findings revealed that, on average, students evidenced statistically significant increases on one form of basic-level comprehension performance over time with no statistically significant difference between QT and comparison classrooms. Given that treatment and comparison classrooms engaged in a district-wide literacy initiative with supplemental daily literacy instruction, these results are not altogether unexpected. However, despite the enhanced literacy instruction across all classes, from Time 2 to Time 3, growth in QT students’ high-level comprehension, as measured via written argumentation essay performance, was statistically significantly greater than their comparison peers’ growth. This study informs the future of education research and practice regarding the feasibility and utility of relevant and rigorous multifaceted literacy interventions focused upon small-group discussion.

Preliminary psychometric properties of a standard vocabulary test administered using a non-invasive brain-computer interface.

ObjectiveTo examine measurement agreement between a vocabulary test that is administered in the standardized manner and a version that is administered with a brain-computer interface (BCI).MethodThe sample was comprised of 21 participants, ages 9–27, mean age 16.7 (5.4) years, 61.9% male, including 10 with congenital spastic cerebral palsy (CP), and 11 comparison peers. Participants completed both standard and BCI-facilitated alternate versions of the Peabody Picture Vocabulary Test - 4 (PPVT™-4). The BCI-facilitated PPVT-4 uses items identical to the unmodified PPVT-4, but each quadrant forced-choice item is presented on a computer screen for use with the BCI.ResultsMeasurement agreement between instruments was excellent, including an intra-class correlation coefficient of 0.98, and Bland-Altman plots and tests indicating adequate limits of agreement and no systematic test version bias. The mean standard score difference between test versions was 2.0 points (SD 6.3).ConclusionThese results demonstrate that BCI-facilitated quadrant forced-choice vocabulary testing has the potential to measure aspects of language without requiring any overt physical or communicative response. Thus, it may be possible to identify the language capabilities and needs of many individuals who have not had access to standardized clinical and research instruments.

A model to evaluate interprofessional training effectiveness: feasibility and five-year outcomes of a multi-site prospective cohort study.

Assessing the impact of interdisciplinary training programs is highly desirable and needed. However, there are currently no established methods to prospectively assess long-term outcomes of trainees compared to individuals who did not receive training. Our objective was to test the feasibility of a longitudinal, prospective cohort design to evaluate training outcomes, and to use this method to evaluate Leadership Education in Neurodevelopmental Disabilities and Related Disorders (LEND) training outcomes. LEND trainees were matched to comparison peers and followed annually for up to five years using a pre-existing outcomes survey. We assessed study feasibility using recruitment and retention data over five years. We then looked at preliminary efficacy of LEND training in LEND trainees compared to comparison peers using the pre-existing outcomes survey. Overall, 68.3% of eligible trainees participated in the Outcomes Study across five years, and 66.0% were matched to comparison peers. On average, 84.4% of LEND trainees and 79.9% of comparison peers completed the outcomes survey annually. Attrition was low at 0.9% for LEND trainees and 2.6% for comparison peers over five years. LEND training demonstrated preliminary efficacy in promoting leadership development: LEND trainees began their careers engaged in more leadership activities than comparison peers, and the rate of growth in their participation in leadership activities was greater. The design used to assess outcomes is a feasible approach that can be widely used to assess training program outcomes. Analyses suggest that LEND training is efficacious in increasing involvement in leadership activities over time after graduation.

Computer-Mediated Communication in Adults With and Without Moderate-to-Severe Traumatic Brain Injury: Survey of Social Media Use.

BackgroundIndividuals with a history of traumatic brain injury (TBI) report fewer social contacts, less social participation, and more social isolation than noninjured peers. Cognitive-communication disabilities may prevent individuals with TBI from accessing the opportunities for social connection afforded by computer-mediated communication, as individuals with TBI report lower overall usage of social media than noninjured peers and substantial challenges with accessibility and usability. Although adaptations for individuals with motor and sensory impairments exist to support social media use, there have been no parallel advances to support individuals with cognitive disabilities, such as those exhibited by some people with TBI. In this study, we take a preliminary step in the development process by learning more about patterns of social media use in individuals with TBI as well as their input and priorities for developing social media adaptations.ObjectiveThis study aims to characterize how and why adults with TBI use social media and computer-mediated communication platforms, to evaluate changes in computer-mediated communication after brain injury, and to elicit suggestions from individuals with TBI to improve access to social media after injury.MethodsWe conducted a web-based survey of 53 individuals with a chronic history of moderate-to-severe TBI and a demographically matched group of 51 noninjured comparison peers.ResultsMore than 90% of participants in both groups had an account on at least one computer-mediated communication platform, with Facebook and Facebook Messenger being the most popular platforms in both groups. Participants with and without a history of TBI reported that they use Facebook more passively than actively and reported that they most frequently maintain web-based relationships with close friends and family members. However, participants with TBI reported less frequently than noninjured comparison participants that they use synchronous videoconferencing platforms, are connected with acquaintances on the web, or use social media as a gateway for offline social connection (eg, to find events). Of the participants with TBI, 23% (12/53) reported a change in their patterns of social media use caused by brain injury and listed concerns about accessibility, safety, and usability as major barriers.ConclusionsAlthough individuals with TBI maintain social media accounts to the same extent as healthy comparisons, some may not use them in a way that promotes social connection. Thus, it is important to design social media adaptations that address the needs and priorities of individuals with TBI, so they can also reap the benefits of social connectedness offered by these platforms. By considering computer-mediated communication as part of individuals’ broader social health, we may be able to increase web-based participation in a way that is meaningful, positive, and beneficial to broader social life.

How Are Families Faring? Perceived Family Functioning Among Adolescent and Young Adult Cancer Survivors in Comparison to Their Peers.

Purpose: Adolescent and young adult (AYA) cancer survivors' families can face ongoing challenges into survivorship. Families' adjustment and functioning as a unit can subsequently impact AYAs' mental health and quality of life. This study examined AYA cancer survivors' perceived family functioning, compared with their peers, and investigated factors associated with family functioning. Methods: Eligible participants were aged between 15 and 40 years, fluent in English, and cancer survivors who had completed treatment. AYA cancer survivors were recruited from hospital clinics, and the comparison group from an affiliated university campus. Participants completed the McMaster Family Assessment Device, Kidcope, and the Depression, Anxiety and Stress Scale-Short Form. We analyzed between-group differences in family functioning using multivariate analysis of covariance and used partial correlations to investigate associations between demographic cancer-related psychological coping variables and family functioning. Results: Ninety-three AYA cancer survivors and 141 comparison peers participated (ages: 15-32 years). AYA cancer survivors reported significantly better family functioning (p = 0.029), lower depression (p = 0.016), and anxiety symptoms (p = 0.008) compared with the comparison group. Approximately one-third of AYA survivors (34.4%) reported clinically significant maladaptive family functioning; however, this was more prevalent in the comparison group (50.4%). After adjusting for covariates, poorer family functioning was associated with AYA survivors using more avoidant escape-oriented coping strategies (p = 0.010). Conclusions: Our cancer survivor cohort reported better family functioning and psychological outcomes compared with their peers. Interventions targeting avoidant coping behaviors may support improved family functioning in some survivors. Further research disentangling the relationship between coping mechanisms and family functioning among AYA cancer survivors is needed.

Beyond the toddler years: A meta-analysis of communicative abilities in siblings of children with autism spectrum disorder.

Communication is a core challenge for individuals on the autism spectrum, and many autistic individuals experience challenges with language. Prospective studies of younger siblings of children with autism show that siblings not only have an increased likelihood of developing autism themselves, but that even siblings without an autism spectrum diagnosis are more likely to have a language delay as toddlers than their peers without familial history of autism (Marrus et al., 2018). While there is substantial variability in the communicative abilities of siblings of children with autism in toddlerhood, it is not clear how these differences translate beyond the first 3 years of life. The present study used meta-analysis to evaluate a wide range of literature and determine whether siblings of children with autism (Sibs-A) over 48 months of age differ from comparison groups in their language and communication abilities. A total of 26 studies describing 22 cohorts were included. Over 2,000 Sibs-A were compared with neurotypical individuals without familial history of autism or siblings of individuals with another neurodevelopmental disability. Meta-analysis revealed a small but significant effect such that Sibs-A performed lower than comparison peers in overall language and communication. Effects were strongest for expressive language and linguistic processing speed, and there were substantially larger differences for experimenter-administered measures than for parent-report, though findings must be considered in the context of other study characteristics. Suggestions based on this meta-analytic review are provided to guide future research in understanding individual differences in the communicative development and outcomes of Sibs-A.

Disability and the COVID-19 Pandemic: A Survey of Individuals With Traumatic Brain Injury

ObjectivesTo identify the consequences of the coronavirus 2019 (COVID-19) pandemic for individuals with traumatic brain injury (TBI), with particular attention to unique effects for individuals with chronic disability. DesignIndividuals with and without a history of TBI completed a web-based survey. SettingParticipants were recruited from the Vanderbilt Brain Injury Patient Registry in Nashville, TN, and completed the survey from their homes between May and June 2020, during social distancing related to the COVID-19 pandemic. ParticipantsParticipants (N=47) in the chronic phase of moderate-severe TBI (>6mo postinjury) and 51 noninjured comparison (NC) peers completed the survey. InterventionsNot applicable. Main Outcome MeasuresParticipants, or respondents, answered a mix of multiple choice and free text questions about how the COVID-19 pandemic has affected their work, education, medical care, social communication, sources of information and decision making, and mental and physical well-being. Individuals with TBI also answered questions about how TBI has affected their experiences of the pandemic. ResultsAs a group, respondents with TBI reported less pandemic-related behavior change (eg, daily habits, virtual social visits, and masking) than NC peers. Both NCs and respondents with TBI identified health care providers as trusted sources of public health information. One-third of individuals with TBI indicated that brain injury has made coping with the pandemic more difficult, and respondents identified mental health challenges and social isolation as key barriers. ConclusionsThese results suggest that health care providers should look for ways to provide tailored education and reduce social isolation for individuals with disability during the ongoing COVID-19 pandemic. We discuss several direct suggestions from participant responses.

Poly-victimization and psychopathological symptoms in adolescence: Examining the potential buffering effect of positive childhood experiences

BackgroundChildhood maltreatment are well-established risk factors for adolescent psychopathology. Positive childhood experiences (PCEs) known protective factors. However, few studies have simultaneously investigated childhood maltreatment and PCEs in the context of longitudinal study. The aim of this paper was to assess the buffering effect of PCEs in adolescence in the association between chronic childhood maltreatment and psychological symptoms in adolescence. MethodsData were from an ongoing longitudinal study with 2288 children aged 8.15 y at baseline who were recruited from 3 large elementary schools in China. Participants were followed up for four waves across 6 years. The associations between re-victimization and poly-victimization with adolescent psychopathological symptoms across different PCEs contexts were explored. ResultsPoly-victimization was highly predictive of depressive symptoms, oppositional defiant disorder and conduct disorder. PCEs may mitigate the negative effect of chronic childhood maltreatment on adolescent psychopathology in a dose-response manner. For adolescents with 4-5 PCEs, psychopathological symptoms score decreased significantly and showed similar level with those low/no-victimization comparison peers. While experiencing multiple PCEs does decrease the risk of psychopathological symptoms, certain PCEs, such as parental warmth and peer support, appear to entailed protective effect on all the three psychopathological symptoms. LimitationsIt is not clear whether the patterns of effects would vary across developmental periods. ConclusionsA focus of interventions should be not only on ameliorating childhood maltreatment, but also on expanding the availability of social support related PCEs, which may help inform suitable strategies for providing intervention and support to best help reduce the psychopathology burden for children.

The Effectiveness of Current Interventions to Reverse the Underachievement of Gifted Students: Findings of a Meta-Analysis and Systematic Review

Underachievement of gifted students has been a great concern for the field of gifted education. The current study reviewed 14 recent empirical studies concerning the effectiveness of underachievement interventions on gifted students’ achievement outcomes and psychosocial outcomes. Overall, there was no evidence that underachievement interventions significantly improved academic performance of gifted underachievers ( g = .09, p = .387), especially in terms of course grades. Gifted underachievers receiving interventions significantly outscored their comparison peers on psychosocial outcomes ( g = 0.22, p = .001), which consisted of a variety of measures on self-efficacy, goal valuation, environmental perceptions, self-regulation/motivation, and psychosocial functioning. Qualitative studies generally reported that gifted underachievers benefited from the interventions in terms of increased motivation for learning, improved self-regulation, and finding school more meaningful. Findings need to be viewed in light of the relatively low quality of the evidence from recent research on underachievement interventions.

The Influence of Parent Distress and Parenting on Bereaved Siblings' Externalizing Problems.

Bereaved siblings experience more externalizing problems compared to non-bereaved peers and norms; however, the mechanisms explaining this phenomenon have not been empirically examined. This study tested the serial indirect effects of sibling bereavement on adolescents' externalizing problems through parent distress (i.e., internalizing symptoms) and parenting (i.e., parenting behaviors, parent-adolescent communication). During home visits, 72 bereaved adolescents (ages 10-18) whose brother/sister died from cancer and 60 comparison peers reported about their externalizing problems and their mothers' and fathers' parenting behaviors (warmth, behavioral control, psychological control) and parent-adolescent communication (open communication, problematic communication). Mothers and fathers reported their own internalizing symptoms. Bereaved siblings reported more externalizing problems (p =.048) and bereaved mothers reported more internalizing symptoms relative to the comparison group (p =.015). Serial multiple mediation models indicated that elevated externalizing problems were partially explained by both bereaved mothers' internalizing symptoms and parenting and communication (less warmth [CI: 0.04, 0.86], more psychological control [CI: 0.03, 0.66], and more problematic mother-adolescent communication [CI: 0.03, 0.79]), with a significant indirect effect also emerging for open mother-adolescent communication [CI: 0.05, 1.59]. Bereaved fathers did not significantly differ in internalizing symptoms from comparison fathers (p =.453), and no significant indirect effects emerged for fathers. Elevated externalizing problems in bereaved siblings may result from mothers' distress and the impact on their parenting and communication. Targeting adjustment and parenting in bereaved mothers following a child's death may reduce externalizing problems in bereaved siblings. Research to evaluate family-centered interventions is needed.

Comprehension of social-legal exchanges in adults with and without traumatic brain injury.

To characterize comprehension of conditional social-legal rules and broader social reasoning in adults with and without traumatic brain injury (TBI). Participants were 20 adults with moderate-to-severe TBI (11 women) and 21 adults without TBI (13 women), ages 24 to 64 years. Participants completed the Wason task, a test of logical reasoning of conditional rules comprising precautionary rules, social-exchange rules, and legal social-exchange rules. Dependent variables were response accuracy and response time. Across rule categories, TBI group participants were significantly less accurate, F(1, 39) = 9.03, p < .01, semipartial R2 = 0.18, and slower, F(1, 39) = 7.32, p < .01, semipartial R2 = 0.16, than comparison peers. Rule category had no effect on accuracy, but for both groups legal social-exchange rules were associated with longer response times, F(1, 78) = 9.82, p < .01, semipartial R2 = 0.11. Processing speed test scores correlated with accuracy, F(1, 37) = 4.62, p < .05, semipartial R2 = 0.11, and response times, F(1, 78) = 4.45, p < .05, semipartial R2 = 0.14, in both groups. Adults with TBI underperformed their uninjured peers in both accuracy and speed of comprehending on precautionary rules, social-exchange rules, and legal social-exchange rules. These differences were attributable in part to differences in processing speed both within and between groups. Results highlight the potential costs of TBI-related cognitive problems in social-legal contexts, suggest the need to better accommodate individuals with TBI who are already involved in legal systems, and identify cognitive mechanisms for future study of social-legal rule comprehension in TBI and other populations with cognitive impairments.

Comprehension of Legal Language by Adults With and Without Traumatic Brain Injury.

To characterize comprehension of written legal language in adults with and without traumatic brain injury (TBI). Nineteen adults with moderate-to-severe TBI (11 females) and 21 adults without TBI (13 females), aged 24 to 64 years. Participants completed a multiple-choice assessment of legal-language comprehension, with written stimuli either presented in their original legal form or manipulated to simplify syntax or use more frequently occurring words. Across stimulus types, TBI group participants were significantly less accurate and slower than comparison peers, with no effect of linguistic manipulation. Working memory and reading fluency test scores correlated with task accuracy and speed in both groups. Adults with TBI underperformed their uninjured peers in both accuracy and speed on a task of legal-language comprehension, and these differences were attributable in part to differences in working memory and reading fluency. Results highlight the potential costs of TBI-related communication problems in criminal proceedings and the need to formally evaluate language comprehension in individuals with TBI who are in the criminal justice system.

The Effect of Optimism and Connectedness on Psychological Adjustment of Children with Cancer and Comparison Peers.

The present study aimed to examine the relationship of optimism and connectedness with psychological adjustment outcomes in children with cancer and determine whether these relations differ for children with cancer and comparison peers. Participants were 155 children with cancer and 143 comparison youth without a history of cancer, aged 8 to 17 years at study entry, who were followed longitudinally over a 3-year period. Participants completed self-report measures at 3 time points: baseline optimism at study entry (T1), connectedness at 1 year after baseline (T2), and emotional symptoms at 3 years after baseline (T3). A series of regression analyses were conducted using conditional process analysis to examine whether connectedness mediated the relationship between optimism and psychological adjustment and whether this was moderated by health status (i.e., history of childhood cancer vs no history of cancer or other serious or chronic illness). Connectedness to parents, peers, and friends significantly mediated the relationship between optimism and psychological adjustment (b parents = -0.1387, 95% confidence interval [CI] [-0.2341 to -0.0515]; b peers = -0.2021, 95% CI [-0.3575 to -0.0818]; b friends = -0.0703, 95% CI [-0.1640 to -0.0050]). However, this mediation was not significantly moderated by having a history of cancer. Cancer history did moderate the direct relationship between optimism and psychological adjustment and between connectedness to parents and psychological adjustment. Findings suggest that patients with cancer are doing remarkably well with regard to adjustment. Connectedness with parents and peers mediates the relationship between optimism and psychological adjustment. As such, children with cancer who are identified as experiencing poor adjustment may benefit from interventions to foster connectedness.

Interpretation of non-verbal cues by people with and without TBI: understanding relationship intentions.

Although long-term social challenges following traumatic brain injury (TBI) are well documented, the challenges of establishing new relationships following TBI are less understood. To examine how the type of non-verbal cues produced by an unfamiliar communication partner impacts feelings of relationship closeness by people with and without TBI. In this quasi-experimental comparative mixed-group design, participants included 12 male heterosexual adults with moderate/severe TBI and 10 typical comparison peers. An adaptation of the Relationship Closeness Induction Task (RCIT), a 29-item questionnaire, was completed by all participants to induce relationship closeness through reciprocal self-disclosure during conversation. Participants completed the RCIT three separate times in counterbalanced order. Conversational partners for the RCIT were three female actors trained to convey similar verbal answers to the RCIT questions, but to produce different non-verbal cues: solicitation (i.e., flirting), neutral and rejecting. Following each conversation, the participants completed a 10-item Likert-type questionnaire about the experience. Between- and within-group non-parametric statistical analysis of Likert questions showed non-significant differences between the two participant groups such that both groups consistently rated the female actor who used flirting non-verbal cues higher than the actor who used rejecting non-verbal cues. These results suggest a small sample of heterosexual males with TBI interpret non-verbal relationship cues in real-time conversations with unfamiliar partners as well as comparison peers. Clinical implications include the need to consider real-time conversation in assessment and treatment planning for social communication goals related to cognitive-communication impairment.

Social-cue perception and mentalizing ability following traumatic brain injury: A human-robot interaction study

ABSTRACTPrimary Objective: Research studies and clinical observations of individuals with traumatic brain injury (TBI) indicate marked deficits in mentalizing—perceiving social information and integrating it into judgements about the affective and mental states of others. The current study investigates social-cognitive mechanisms that underlie mentalizing ability to advance our understanding of social consequences of TBI and inform the development of more effective clinical interventions.Research Design: The study followed a mixed-design experiment, manipulating the presence of a mentalizing gaze cue across trials and participant population (TBI vs. healthy comparisons).Methods and Procedures: Participants, 153 adults, 74 with moderate-severe TBI and 79 demographically matched healthy comparison peers, were asked to judge a humanoid robot’s mental state based on precisely controlled gaze cues presented by the robot and apply those judgements to respond accurately on the experimental task.Main Outcomes and Results: Results showed that, contrary to our hypothesis, the social cues improved task performance in the TBI group but not the healthy comparison group.Conclusions: Results provide evidence that, in specific contexts, individuals with TBI can perceive, correctly recognize, and integrate dynamic gaze cues and motivate further research to understand why this ability may not translate to day-to-day social interactions.
