Anderson V, Hearps SJC, Catroppa C, Beauchamp MH, Ryan NP. What predicts persisting social impairment following pediatric traumatic brain injury: contribution of a biopsychosocial approach. Psychol Med 2023; 53:3568-3579. [PMID: 35189999 PMCID: PMC10277758 DOI: 10.1017/s0033291722000186] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/18/2021] [Revised: 01/06/2022] [Accepted: 01/13/2022] [Indexed: 11/06/2022]
Abstract
BACKGROUND Psychosocial deficits, such as emotional, behavioral and social problems, reflect the most common and disabling consequences of pediatric traumatic brain injury (TBI). Their causes and recovery likely differ from physical and cognitive skills, due to disruption to developing brain networks and the influence of the child's environment. Despite increasing recognition of post-injury behavioral and social problems, there exists a paucity of research regarding the incidence of social impairment, and factors predicting risk and resilience in the social domain over time since injury. METHODS Using a prospective, longitudinal design, and a bio-psychosocial framework, we studied children with TBI (n = 107) at baseline (pre-injury function), 6 months, 1 and 2-years post-injury. We assessed intellectual ability, attention/executive function, social cognition, social communication and socio-emotional function. Children underwent structural magnetic resonance imaging (MRI) at 2-8 weeks post-injury. Parents rated their child's socio-emotional function and their own mental health, family function and perceived burden. RESULTS We distinguished five social recovery profiles, characterized by a complex interplay between environment and pre- and post-TBI factors, with injury factors playing a lesser role. Resilience in social competence was linked to intact family and parent function, intact pre-injury adaptive abilities, post-TBI cognition and social participation. Vulnerability in the social domain was related to poor pre- and post-injury adaptive abilities, greater behavioral concerns, and poorer pre- and post-injury parent health and family function. CONCLUSIONS We identified five distinct social recovery trajectories post-child-TBI, each characterized by a unique biopsychosocial profile, highlighting the importance of comprehensive social assessment and understanding of factors contributing to social impairment, to target resources and interventions to children at highest risk.

Abstract
This preliminary study investigated the interaction between working memory and social cognition in adolescents and young adults with traumatic brain injury (TBI). It was hypothesized that participants with or without TBI would better recognize social information when working memory or social cognitive load was low, and that adolescents and young adults with TBI would be more affected by increased cognitive demand than their uninjured peers. Eight adolescents and young adults with complicated mild-severe TBI (aged 14-22 years) and eight age- and sex-matched typically developing (TD) adolescents completed computer-based n-back tasks requiring recognition of either face identity or facial affect, with 0-back, 1-, and 2-back conditions. The TBI group had lower scores overall than the TD group, and scores for both groups were lower for affect recognition than identity recognition. Scores for both groups were lower in conditions with a higher working memory load. There was a significant group-by-working memory interaction, with larger group differences in high-working memory conditions. Study results and their potential implications for social outcomes are discussed.

Abstract
Children and adolescents who survive the pediatric intensive care unit (PICU) with an acquired brain injury (ABI) often demonstrate a variety of physical, cognitive, emotional/behavioral, and social sequelae termed post-intensive care syndrome (PICS). Social communication and interaction challenges have also been observed clinically, and there is growing literature documenting these occurrences in youth following ABI. The extent of these social changes varies among patients, and a subset of patients go on to exhibit social and behavioral profiles closely resembling those of autistic youth. We reviewed empirical research regarding social functioning in youth following ABI, as well as the overlap between individuals with ABI and autistic youth, published from January 2009 to August 2022 on PubMed and Scopus databases. Clinical case examples from a well-established post-PICU follow-up program are also provided to exemplify the complexity of this phenomenon.

Abstract
In acquired brain injury (ABI), social cognition is a contributing factor to the changes observed in functional outcomes. However, progress in assessing and understanding social cognitive impairments is limited by a lack of consistency in terminology and the proliferation in assessment tools, leading to a lack of consensus on what should be assessed and how. This review aims to examine the domains of social cognition commonly assessed in ABI, the assessment tools used, and the appropriateness of these tools for researchers and clinicians. Using the Arksey and O'Malley scoping review methodology, 367 articles reporting results from 10,930 people with an ABI met our inclusion criteria. The five most commonly assessed domains of social cognition were emotion perception, theory of mind, social communication, identity recognition and empathy. The most commonly used measure of these domains included: the Ekman and Friesen photo series, Faux Pas Recognition Test, La Trobe Communication Questionnaire, Benton Facial Recognition Test and the Interpersonal Reactivity Index. There are well-validated measures readily available that are underused in favour of non-standardized measures clinically or the development of one's own measure in research. The appropriateness of the identified measure for research and clinical use was discussed, including suggestions for future research.

Abstract
BACKGROUND In 2020 and 2021, people increasingly used the internet to connect socially and professionally. However, people with an acquired brain injury (ABI) experience challenges in using social media, and rehabilitation professionals have reported feeling underprepared to support them in its use. To date, no review of social media skills training to inform ABI rehabilitation has been conducted. OBJECTIVE This scoping review aimed to examine research on interventions addressing social media skills and safety, with a focus on people living with health conditions; free web-based resources for the general public on social media skills training; and currently available online support groups for people with ABI. METHODS An integrative scoping review was conducted, with a systematic search strategy applied in March and November 2020 across OvidSP (MEDLINE, AMED, PsycINFO, and Embase), Scopus, Web of Science, CINAHL, Google Scholar, Google, and Facebook. The data collected were critically appraised and synthesized to describe the key content and features of social media training resources. RESULTS This review identified 47 peer-reviewed academic articles, 48 social media training websites, and 120 online support groups for people with ABI. A key recommendation was interactive training with practical components addressing cybersafety, how to use platforms, and how to connect with others. However, no social media training resources that were relevant and accessible for people with ABI were identified. CONCLUSIONS Training resources to support people with ABI in safely using social media are limited. The key content to be addressed and the features to be incorporated into web-based social media training were determined, including the need for interactive training that is co-designed and safe and incorporates practical components that support people with ABI. These findings can be used to inform the development of web-based evidence-based support for people with ABI who may be vulnerable when participating in social media.

Abstract
Traumatic brain injury (TBI) during critical periods of early-life brain development can affect the normal formation of brain networks responsible for a range of complex social behaviors. Because of the protracted nature of brain and behavioral development, deficits in cognitive and socioaffective behaviors may not become evident until late adolescence and early adulthood, when such skills are expected to reach maturity. In addition, multiple pre- and post-injury factors can interact with the effects of early brain insult to influence long-term outcomes. In recent years, with advancements in magnetic-resonance-based neuroimaging techniques and analysis, studies of the pediatric population have revealed a link between neurobehavioral deficits, such as social dysfunction, with white matter damage. In this review, in which we focus on contributions from Australian researchers to the field, we have highlighted pioneering longitudinal studies in pediatric TBI, in relation to social deficits specifically. We also discuss the use of advanced neuroimaging and novel behavioral assays in animal models of TBI in the immature brain. Together, this research aims to understand the relationship between injury consequences and ongoing brain development after pediatric TBI, which promises to improve prediction of the behavioral deficits that emerge in the years subsequent to early-life injury.

Abstract
Recent evidence suggests social cognitive deficits may be among the most profound and disabling consequences of childhood traumatic brain injury (TBI); however, it is only over the last decade that this area has received increasing research attention. This study aims to systematically review all studies reporting on the effects of childhood TBI on social cognition. Meta-analytic techniques were employed to determine the magnitude of social cognitive deficits in childhood TBI. Literature searches were conducted in electronic databases (Medline/PubMed, Scopus, Cochrane, EMBASE, PsycINFO and CINAHL) to retrieve relevant articles on social cognitive outcomes of paediatric TBI published from 2007-2019. The systematic review identified fourteen eligible studies, which examined the effect of paediatric TBI on five dimensions of social cognition, including emotion recognition or perception, theory of Mind (ToM), pragmatic language, moral reasoning, and social problem solving. Of these studies, eleven articles were included in subsequent meta-analyses, which included 482 children with TBI. Meta-analysis using a random-effects model revealed non-significant differences between TBI and typically developing (TD) control groups on measures of emotion perception or recognition. In contrast, children and adolescents with TBI performed significantly worse than control groups on ToM and pragmatic language tasks, with small and medium effect sizes, respectively (Hedge's g = -0.46; -0.73). Meta-regression indicated that post-injury social cognitive deficits were not moderated by child age. While the effect of time since injury was not statistically significant, poorer social cognitive outcomes are documented soon after injury. Despite relatively intact basic social cognitive skills (i.e. emotion perception or recognition) children and adolescents with TBI are vulnerable to deficits in higher-order aspects of social cognition, including ToM and pragmatic language. These findings underscore the importance of further research, using well-validated, standardised outcome instruments, in larger paediatric TBI samples. Furthermore, longitudinal prospective studies are needed to evaluate the respective contribution of injury and non-injury factors to individual variation in outcome and recovery of social cognition after paediatric TBI.

Abstract
Childhood traumatic brain injury (TBI) affects over 600 000 children per year in the United States. Following TBI, children are vulnerable to deficits in psychosocial adjustment and neurocognition, including social cognition, which persist long-term. They are also susceptible to direct and secondary damage to related brain networks. In this study, we examine whether brain morphometry of the mentalizing network (MN) and theory of mind (ToM; one component of social cognition) mediates the effects of TBI on adjustment. Children with severe TBI (n = 15, Mage = 10.32), complicated mild/moderate TBI (n = 30, Mage = 10.81) and orthopedic injury (OI; n = 42, Mage = 10.65) completed measures of ToM and executive function and underwent MRI; parents rated children’s psychosocial adjustment. Children with severe TBI demonstrated reduced right-hemisphere MN volume, and poorer ToM, vs children with OI. Ordinary least-squares path analysis indicated that right-hemisphere MN volume and ToM mediated the association between severe TBI and adjustment. Parallel analyses substituting the central executive network and executive function were not significant, suggesting some model specificity. Children at greatest risk of poor adjustment after TBI could be identified based in part on neuroimaging of social brain networks and assessment of social cognition and thereby more effectively allocate limited intervention resources.

Abstract
Social interaction is closely associated with both functional capacity and well-being. Previous research has not only revealed evidence of social dysfunction in individuals with a wide range of psychiatric and neurological disorders but also generated an abundance of potential measures for assessing social cognition. This review explores the most popular measures used within neuropsychiatric populations to investigate the ability to recognize or reason about the mental states of others. Measures are also critically analyzed in terms of strengths and limitations to aid task selection in future clinical studies. The most frequently applied assessment tools use verbal, visual or audiovisual forms of presentation and assess recognition of mental states from facial features, self-rated empathy, the understanding of other's cognitive mental states such as beliefs and intentions, or the ability to combine knowledge of other's thoughts and emotions in order to understand subtle communications or socially inappropriate behavior. Key weaknesses of previous research include limited investigation of relationships with clinical symptoms, and underutilization of measures of everyday social functioning that offer a useful counterpart to traditional "lab" tasks. Future studies should aim to carefully select measures not only based on the range of skills to be assessed but also taking into account potential difficulties with interpretation and the need to gain insight into the application of social cognitive skills as well as ability per se. Some of the best measures include those with well-matched control trials (e.g., Yoni Task) or those that restrict the influence of verbal deficits (e.g., intentions comic strip task), elicit spontaneous mentalizing (e.g., Animations Task), and possess greater ecological validity (e.g., Movie for the Assessment of Social Cognition). Social cognitive research within psychiatric populations will be further enhanced through the development of more closely matched control tasks, and the exploration of relationships between task performance, medication, strategy use, and broader emotional and motor functions.

Abstract
PURPOSE Central nervous system (CNS) prophylaxis in the treatment of childhood acute lymphoblastic leukaemia (ALL) is routinely achieved through intrathecal chemotherapy (ITC). The presence of high level language deficits in older children who received CNS-directed ITC for ALL in early childhood is yet to be elucidated, with previous research suggesting that high level language deficits may appear later in ALL survivors' development at an age when these skills typically emerge. METHOD A test battery covering foundational language skills and higher-order language skills was administered to five participants (aged 10-15 years) with a history of ITC for ALL. Conversion of each child's language performance scores to z scores allowed for clinical interpretation of data across the language areas tested. RESULT Foundational language skills were, in general, of no clinical concern. Three of the five children presented with clinically impaired language skills in areas including resolving ambiguity, making inferences and composing novel sentences. Performance variation between the participants and within the individual participants was noted. CONCLUSION Given the importance of early adolescent language abilities to academic and social development in late primary and secondary schooling, these preliminary findings suggest further research into emerging adolescent language abilities following ITC for ALL is warranted.

Abstract
In schizophrenia, abnormalities in structural connectivity between brain regions known to contain mirror neurons and their relationship to negative symptoms related to a domain of social cognition are not well understood. Diffusion tensor imaging (DTI) scans were acquired in 16 patients with first episode schizophrenia and 16 matched healthy controls. FA and Trace of the tracts interconnecting regions known to be rich in mirror neurons, i.e., anterior cingulate cortex (ACC), inferior parietal lobe (IPL) and premotor cortex (PMC) were evaluated. A significant group effect for Trace was observed in IPL-PMC white matter fiber tract (F (1, 28) = 7.13, p = .012), as well as in the PMC-ACC white matter fiber tract (F (1, 28) = 4.64, p = .040). There were no group differences in FA. In addition, patients with schizophrenia showed a significant positive correlation between the Trace of the left IPL-PMC white matter fiber tract, and the Ability to Feel Intimacy and Closeness score (rho = .57, p = 0.034), and a negative correlation between the Trace of the left PMC-ACC and the Relationships with Friends and Peers score (rho = remove -.54, p = 0.049). We have demonstrated disrupted white mater microstructure within the white matter tracts subserving brain regions containing mirror neurons. We further showed that such structural disruptions might impact negative symptoms and, more specifically, contribute to the inability to feel intimacy (a measure conceptually related to theory of mind) in first episode schizophrenia. Further studies are needed to understand the potential of our results for diagnosis, prognosis and therapeutic interventions.

Abstract
OBJECTIVE (1) To investigate outcomes in language competence and self-reported satisfaction with social relationships in long-term survivors of childhood traumatic brain injury (TBI); and (2) to establish whether language competence contributes to self-reported satisfaction with social relationships decades after sustaining childhood TBI. PARTICIPANTS Twelve females and 8 males aged 30 to 55 (mean = 39.80, standard deviation = 7.54) years who sustained a TBI during childhood and were on average 31 years postinjury (standard deviation = 9.69). An additional 20 participants matched for age, sex, handedness, years of education, and socioeconomic status constituted a control group. MAIN MEASURES Test of Language Competence-Expanded Edition and the Quality of Life in Brain Injury questionnaire. RESULTS Individuals with a history of childhood TBI performed significantly poorer than their non-injured peers on 2 (Ambiguous Sentences and Oral Expression: Recreating Sentences) out of the 4 Test of Language Competence-Expanded Edition subtests used and on the Quality of Life in Brain Injury subscale assessing satisfaction with social relationships. In the TBI group, scores obtained on the Ambiguous Sentences subtest were found to be a significant predictor of satisfaction with social relationships, explaining 25% of the variance observed. CONCLUSIONS The implication of high-level language skills to self-reported satisfaction with social relationships many decades post-childhood TBI suggests that ongoing monitoring of emerging language skills and support throughout the school years and into adulthood may be warranted if adult survivors of childhood TBI are to experience satisfying social relationships.

Abstract
BACKGROUND Deficits in social cognition may be among the most profound and disabling sequelae of paediatric traumatic brain injury (TBI); however, the neuroanatomical correlates of longitudinal outcomes in this domain remain unexplored. This study aimed to characterize social cognitive outcomes longitudinally after paediatric TBI, and to evaluate the use of sub-acute diffusion tensor imaging (DTI) to predict these outcomes. METHODS The sample included 52 children with mild complex-severe TBI who were assessed on cognitive theory of mind (ToM), pragmatic language and affective ToM at 6- and 24-months post-injury. For comparison, 43 typically developing controls (TDCs) of similar age and sex were recruited. DTI data were acquired sub-acutely (mean = 5.5 weeks post-injury) in a subset of 65 children (TBI = 35; TDC = 30) to evaluate longitudinal prospective relationships between white matter microstructure assessed using Tract-Based Spatial Statistics and social cognitive outcomes. RESULTS Whole brain voxel-wise analysis revealed significantly higher mean diffusivity (MD), axial diffusivity (AD) and radial diffusivity (RD) in the sub-acute TBI group compared with TDC, with differences observed predominantly in the splenium of the corpus callosum (sCC), sagittal stratum (SS), dorsal cingulum (DC), uncinate fasciculus (UF) and middle and superior cerebellar peduncles (MCP & SCP, respectively). Relative to TDCs, children with TBI showed poorer cognitive ToM, affective ToM and pragmatic language at 6-months post-insult, and those deficits were related to abnormal diffusivity of the sCC, SS, DC, UF, MCP and SCP. Moreover, children with TBI showed poorer affective ToM and pragmatic language at 24-months post-injury, and those outcomes were predicted by sub-acute alterations in diffusivity of the DC and MCP. CONCLUSIONS Abnormal microstructure within frontal-temporal, limbic and cerebro-cerebellar white matter may be a risk factor for long-term social difficulties observed in children with TBI. DTI may have potential to unlock early prognostic markers of long-term social outcomes.

Abstract
The purpose of this study was to characterize pragmatic deficits after childhood traumatic brain injury (TBI) within the home environment social contexts where they occur. We used a descriptive qualitative approach to describe parents' experiences in communicating with their child with TBI. Participants were ten mothers of children ages 6-12 years who had sustained a moderate to severe TBI more than one year prior to the study. Mothers' experiences were collected through semi-structured interviews and questionnaires. Interviews were analyzed using a deductive framework to develop social contexts and pragmatic deficit themes for communication in the home. Overall, mothers primarily described their children with TBI as exhibiting average or near average pragmatic skills at home, but nine observed some pragmatic deficits and/or social behavior problems. There were four in-home social contexts in which pragmatic deficits were observed. Emergent themes also included outside-of-the home social contexts and social behavior problems. There was some overlap of pragmatic deficit and social behavior problem themes among contexts, but many deficits were context specific. This study's pragmatic deficit themes expanded on prior childhood TBI pragmatic investigations by identifying contexts in and outside of the home in which pragmatic deficits may occur after TBI. Learning Outcomes Readers will be able to describe the day-to-day social contexts that may be impacted by pragmatic deficits after childhood TBI. Readers will be able to compare the pragmatic deficit themes identified as occurring in the home to those occurring outside of the home.

Abstract
Social cognition refers to the ability to use social cues to infer the meaning and intentions behind the behaviour of others in order to respond in a socially adaptive manner. It is increasingly recognised that disorders of social cognition, including problems with emotion perception, theory of mind, conversational inference, morality judgements, decision making and social inhibition, characterise many developmental and psychiatric disorders and are highly relevant to many with acquired brain injuries or diseases, especially the frontotemporal dementias. This review provides an introduction and overview of the papers in this special edition on social cognition and places these in the context of other recent research. In doing so, several current issues in the clinical management of social cognition are delineated. Given that social cognition seems to be a sensitive predictor of psychosocial function, the assessment of social cognition is seen by many clinicians to be important although which profession is responsible is yet to be resolved. Issues in how social cognition are assessed are discussed, including the importance of context to social cognition, its interactive nature and the need to recognise influences such as family upbringing, gender and emotional state on social cognitive performance. There also needs to be development of tests that address all aspects of social cognition, including decision making and inhibition. Finally, this review discusses intervention research. Interventions are especially well developed in relation to schizophrenia, and less well developed in brain injury. These appear to be generally effective although treatments for emotional self-awareness are yet to be developed.

Abstract
Given the pivotal role that social interactions play for adolescents' well-being, understanding the factors that influence communication is key. The present study examined relations between adolescents' communicative perspective-taking, executive function skills, and ADHD traits and explored the role communicative perspective-taking plays in peer relations. Data was collected from a community sample of 15 to 19-years-olds (N = 46) in Waterloo, Canada. Two communicative perspective-taking tasks required participants to infer speakers' communicative intentions. A battery of tasks assessed adolescents' working memory and inhibitory control. Elevated ADHD traits were associated with weaker working memory, inhibitory control, and communicative perspective-taking. Working memory was the strongest predictor of communicative perspective-taking. Highlighting the importance of communicative perspective-taking for social interactions, adolescents with weaker skills in this area reported worse peer relations. Findings underscore the importance of communicative perspective-taking for adolescents' social relations and have relevance for understanding the social difficulties faced by adolescents with elevated ADHD traits.

Abstract
PURPOSE (i) To systematically review longitudinal and prognostic studies relating to the trajectory of cognitive-communication recovery after TBI and (ii) to provide recommendations to strengthen future research. METHOD Thirteen health literature databases were accessed up until July 2014. MAIN MEASURES Articles were screened systematically against pre-determined inclusion and exclusion criteria. Quality reviews were performed on the selected articles using a modified Downs & Black Rating Scale. Two independent reviewers performed the reviews. RESULT Sixteen longitudinal and prognostic articles met the inclusion criteria. There was evidence of either maintenance or improvement of cognitive-communication skills during the first 3 years post-injury. However, the studies did not provide detailed recovery trajectories, by failing to evaluate numerous data points over time. No studies evaluated recovery beyond 3 years post-injury. Injury severity, lesion location, brain volume loss and conversation skills may predict specific cognitive-communication outcomes. There was high variability in study characteristics and measures. CONCLUSION There is currently scarce evidence regarding cognitive-communication recovery and prognosis. People with TBI may recover or maintain pre-morbid cognitive-communication skills during the early rehabilitation stage. Further research detailing the recovery trajectory with a view to evaluating predictive factors is strongly indicated. Guidelines for future research are provided.

Abstract
Recognition of facial affect has been studied extensively in adults with and without traumatic brain injury (TBI), mostly by asking examinees to match basic emotion words to isolated faces. This method may not capture affect labelling in everyday life when faces are in context and choices are open-ended. To examine effects of context and response format, we asked 148 undergraduate students to label emotions shown on faces either in isolation or in natural visual scenes. Responses were categorised as representing basic emotions, social emotions, cognitive state terms, or appraisals. We used students' responses to create a scoring system that was applied prospectively to five men with TBI. In both groups, over 50% of responses were neither basic emotion words nor synonyms, and there was no significant difference in response types between faces alone vs. in scenes. Adults with TBI used labels not seen in students' responses, talked more overall, and often gave multiple labels for one photo. Results suggest benefits of moving beyond forced-choice tests of faces in isolation to fully characterise affect recognition in adults with and without TBI.

Abstract
Primary objective: Social cognition underlies social skills and can be disrupted in numerous developmental and acquired brain disorders during childhood and adolescence. Despite this, there are few tools to assess social cognition clinically in this age group. This study examined adolescent performance on The Awareness of Social Inference Test (TASIT), a valid measure of social cognition in adults.Design: Cross-sectional design examining performance on Parts 1, 2 and 3 of TASIT (and alternate forms) in Australian girls and boys with varying levels of English familiarity.Methods: 665 schoolchildren from private and government schools were administered TASIT subtests. Of these, 464 students aged 13–15 were selected to provide normative data. Scores from a further 97 provided information about the effects of lack of English familiarity.Results: The two Forms of TASIT were statistically equivalent for two of the three parts. Adolescents performed lower than adults, although the differences were not large. Some incremental effects were seen for chronological age. Gender effects were apparent on all subtests. Lack of English familiarity (i.e., English not spoken at home) reduced scores a further 6–13% relative to high English proficiency.Conclusions: TASIT appears to be suitable for adolescents. Norms are best aggregated across ages in adolescence and stratified according to gender.

Abstract
Despite the life-long implications of social and communication dysfunction after pediatric traumatic brain injury, there is a poor understanding of these deficits in terms of their developmental trajectory and underlying mechanisms. In a well-characterized murine model of pediatric brain injury, we recently demonstrated that pronounced deficits in social interactions emerge across maturation to adulthood after injury at postnatal day (p) 21, approximating a toddler-aged child. Extending these findings, we here hypothesized that these social deficits are dependent upon brain maturation at the time of injury, and coincide with abnormal sociosexual behaviors and communication. Age-dependent vulnerability of the developing brain to social deficits was addressed by comparing behavioral and neuroanatomical outcomes in mice injured at either a pediatric age (p21) or during adolescence (p35). Sociosexual behaviors including social investigation and mounting were evaluated in a resident-intruder paradigm at adulthood. These outcomes were complemented by assays of urine scent marking and ultrasonic vocalizations as indices of social communication. We provide evidence of sociosexual deficits after brain injury at p21, which manifest as reduced mounting behavior and scent marking towards an unfamiliar female at adulthood. In contrast, with the exception of the loss of social recognition in a three-chamber social approach task, mice that received TBI at adolescence were remarkably resilient to social deficits at adulthood. Increased emission of ultrasonic vocalizations (USVs) as well as preferential emission of high frequency USVs after injury was dependent upon both the stimulus and prior social experience. Contrary to the hypothesis that changes in white matter volume may underlie social dysfunction, injury at both p21 and p35 resulted in a similar degree of atrophy of the corpus callosum by adulthood. However, loss of hippocampal tissue was greater after p21 compared to p35 injury, suggesting that a longer period of lesion progression or differences in the kinetics of secondary pathogenesis after p21 injury may contribute to observed behavioral differences. Together, these findings indicate vulnerability of the developing brain to social dysfunction, and suggest that a younger age-at-insult results in poorer social and sociosexual outcomes.

Abstract
College students who drink vary in the extent to which they experience drinking consequences, prompting a need to identify factors that differentiate higher-risk drinkers from others. The present study investigated whether difficulty in processing subtle social information is related to negative drinking consequences experienced within the past year. Specifically, poor ability to detect subtle non-verbal sarcasm cues was predicted to contribute to drinking consequences. Participants were 39 women, aged 18 to 27 (M=22), who were enrolled in a public, four-year university. Participants completed a video measure of ability to detect sarcastic comments. After controlling for (high school drinking consequences, maximum drinks in the past 3 months, age), poorer performance in the Simple Sarcasm condition (which provided no cues to others' intentions) explained an additional 10.8% of the variance in recent drinking consequences (ΔF (1, 34)=6.15, p=.018). When predicting risky/hazardous alcohol use consequences (e.g., driving intoxicated, fights, unplanned/unprotected sex), Simple Sarcasm again improved prediction by explaining an additional 8.6% of the variance (ΔF (1, 34)=4.75, p=.036). Sarcasm conditions that provided additional cues to others' meanings were unrelated to alcohol consequences. Findings are discussed within the context of neurological (orbito-frontal-subcortical) pathways that are common to social information and alcohol reinforcement processes.
