White matter tract signatures of impaired social cognition in frontotemporal lobar degeneration.

Impairments of social cognition are often leading features in frontotemporal lobar degeneration (FTLD) and likely to reflect large-scale brain network disintegration. However, the neuroanatomical basis of impaired social cognition in FTLD and the role of white matter connections have not been defined. Here we assessed social cognition in a cohort of patients representing two core syndromes of FTLD, behavioural variant frontotemporal dementia (bvFTD; n = 29) and semantic variant primary progressive aphasia (svPPA; n = 15), relative to healthy older individuals (n = 37) using two components of the Awareness of Social Inference Test, canonical emotion identification and sarcasm identification. Diffusion tensor imaging (DTI) was used to derive white matter tract correlates of social cognition performance and compared with the distribution of grey matter atrophy on voxel-based morphometry. The bvFTD and svPPA groups showed comparably severe deficits for identification of canonical emotions and sarcasm, and these deficits were correlated with distributed and overlapping white matter tract alterations particularly affecting frontotemporal connections in the right cerebral hemisphere. The most robust DTI associations were identified in white matter tracts linking cognitive and evaluative processing with emotional responses: anterior thalamic radiation, fornix (emotion identification) and uncinate fasciculus (sarcasm identification). DTI associations of impaired social cognition were more consistent than corresponding grey matter associations. These findings delineate a brain network substrate for the social impairment that characterises FTLD syndromes. The findings further suggest that DTI can generate sensitive and functionally relevant indexes of white matter damage in FTLD, with potential to transcend conventional syndrome boundaries.

Performance of healthy subjects on an ecologically valid test for social cognition: The short, Dutch Version of The Awareness of Social Inference Test (TASIT)

The present paper addresses the psychometric quality of the shortened Dutch version of The Awareness of Social Inference Test (TASIT), a social cognition task comprising dynamic social interactions. Because the original TASIT required a rather long administration time, two shortened parallel forms were developed. Results showed that TASIT–short was feasible and that the two alternate forms were reasonably comparable in a group of neurologically healthy individuals (N = 98). Also, the results confirmed the ecological validity of TASIT–short in this healthy group. The test appeared sensitive to brain injury as it differentiated between the healthy subjects and a group of patients with acquired brain injury (N = 16). On the basis of the present study we conclude that TASIT–short has added value to the assessment of social cognition in patients with acquired brain injury.

Social perception in adults with Parkinson's disease.

Our study assessed how nondemented patients with Parkinson's disease (PD) interpret the affective and mental states of others from spoken language (adopt a "theory of mind") in ecologically valid social contexts. A secondary goal was to examine the relationship between emotion processing, mentalizing, and executive functions in PD during interpersonal communication. Fifteen adults with PD and 16 healthy adults completed The Awareness of Social Inference Test, a standardized tool comprised of videotaped vignettes of everyday social interactions (McDonald, Flanagan, Rollins, & Kinch, 2003). Individual subtests assessed participants' ability to recognize basic emotions and to infer speaker intentions (sincerity, lies, sarcasm) from verbal and nonverbal cues, and to judge speaker knowledge, beliefs, and feelings. A comprehensive neuropsychological evaluation was also conducted. Patients with mild-moderate PD were impaired in the ability to infer "enriched" social intentions, such as sarcasm or lies, from nonliteral remarks; in contrast, adults with and without PD showed a similar capacity to recognize emotions and social intentions meant to be literal. In the PD group, difficulties using theory of mind to draw complex social inferences were significantly correlated with limitations in working memory and executive functioning. In early PD, functional compromise of the frontal-striatal-dorsal system yields impairments in social perception and understanding nonliteral speaker intentions that draw upon cognitive theory of mind. Deficits in social perception in PD are exacerbated by a decline in executive resources, which could hamper the strategic deployment of attention to multiple information sources necessary to infer social intentions.

Degradation of emotion processing ability in corticobasal syndrome and Alzheimer’s disease

Disturbed emotion processing and difficulty with social interactions are present to variable degrees in dementia. They are characteristic features of frontotemporal dementia, whereas these deficits tend to be mild in Alzheimer's disease, reflecting the different patterns of neurodegeneration seen in these disorders. Corticobasal syndrome is an atypical parkinsonian disorder clinically and pathologically related to frontotemporal dementia. Corticobasal syndrome typically presents as a motor disturbance, although cognitive and behavioural changes are now recognized. Pathological changes are found in frontoparietal cortical regions and in the basal ganglia; regions that are heavily involved in emotion processing. Despite the overlap with frontotemporal dementia and the observed regions of brain atrophy, emotion processing has not been systematically explored in corticobasal syndrome. This study aimed to (i) comprehensively examine emotion processing in corticobasal syndrome in comparison to Alzheimer's disease, to determine whether emotion processing deficits exist in this syndrome, beyond those seen in Alzheimer's disease; and (ii) identify the neural correlates underlying emotion processing in corticobasal syndrome and Alzheimer's disease. Sixteen patients with corticobasal syndrome, 18 patients with Alzheimer's disease and 22 matched healthy control subjects were assessed on a comprehensive battery of face and emotion processing tasks. Behavioural analyses revealed deficits in both basic face processing and high-level emotion processing tasks in patients with corticobasal syndrome. Notably, the emotion processing disturbance persisted even after controlling for face processing deficits. In contrast, patients with Alzheimer's disease were impaired on high-level complex and cognitively demanding emotion recognition tasks (Ekman 60, The Awareness of Social Inference Test) only. Neuroimaging analyses using FreeSurfer revealed that emotion processing deficits in corticobasal syndrome were associated with basal ganglia volume loss as well as cortical thinning of the left paracentral gyrus/precuneus region. In Alzheimer's disease, however, emotion processing deficits were associated with atrophy in a different set of brain regions, including the right cingulate and the bilateral insulae, as well as the hippocampi, right amygdala and nucleus accumbens bilaterally. Our results demonstrate that patients with corticobasal syndrome experience widespread deficits in emotion processing, and these deficits are related to changes in brain regions known to be crucial for emotion processing. These findings have important clinical implications for the treatment and management of these patients.

Oxytocin administration enhances controlled social cognition in patients with schizophrenia.

Individuals with schizophrenia have functionally significant deficits in automatic and controlled social cognition, but no currently available pharmacologic treatments reduce these deficits. The neuropeptide oxytocin has multiple prosocial effects when administered intranasally in humans and there is growing interest in its therapeutic potential in schizophrenia. We administered 40 IU of oxytocin and saline placebo intranasally to 29 male subjects with schizophrenia and 31 age-matched, healthy controls in a randomized, double-blind, placebo-controlled, cross-over study. Social cognition was assessed with The Awareness of Social Inference Test (TASIT) and the Reading the Mind in the Eyes Test (RMET). We examined the effects of oxytocin administration on automatic social cognition (the ability to rapidly interpret and understand emotional cues from the voice, face, and body); controlled social cognition (the ability to comprehend indirectly expressed emotions, thoughts, and intentions through complex deliberations over longer time periods); and a control task (the ability to comprehend truthful dialog and perform general task procedures) in individuals with and without schizophrenia using mixed factorial analysis of variance models. Patients with schizophrenia showed significant impairments in automatic and controlled social cognition compared to healthy controls, and administration of oxytocin significantly improved their controlled, but not automatic, social cognition, F(1, 58)=8.75; p=0.004. Conversely, oxytocin administration had limited effects on social cognition in healthy participants. Patients and controls performed equally well and there were no effects of oxytocin administration on the control task. Intact social cognitive abilities are associated with better functional outcomes in individuals with schizophrenia. Our data highlight the potentially complex effects of oxytocin on some but not all aspects of social cognition, and support the exploration of intranasal oxytocin as a potential adjunct treatment to improve controlled social cognition in schizophrenia.

Emotion Recognition From Dynamic Emotional Displays in Children With ADHD

Children with attention-deficit/hyperactivity disorder (ADHD) often engage in ineffective or inappropriate social interactions and have been shown to be less accurate at interpreting emotions than typically developing controls. Twenty-four children with a clinical diagnosis of ADHD were compared with 24 age and verbal IQ matched controls using an Emotion Evaluation Test (EET) from The Awareness of Social Inference Test (TA SIT). The task assessed interpretation of naturalistic emotional displays including facial movement, tone of voice, and gestures. In each form, 28 vignettes of neutral scripts were enacted by professional actors to represent seven basic emotional categories: Fear, Anger, Sadness, Disgust, Surprise, Happiness as well as a neutral category. The children with ADHD performed more poorly than their age and intelligence matched controls and errors were observed across both positive and negative emotions. The results are discussed in light of problems in recognizing social and contextual cues ...

EPA-0777 – Alexithymia, facial emotion identification and social inference in ed patients: a case-control study

Introduction Alexythimia, reduced cognitive empathy and emotion awareness and understanding are present among individuals with Eating Disorders (EDs). Facial expression is a reliable marker of emotion and an important source of social information. Thus, the ability to judge facial expression is essential for successful interpersonal interactions. Objectives To evaluate alexythimia, facial emotion identification and social inference abilities in a sample of ED patients, compared to a sample of patients with another psychiatric diagnosis and a group of healthy controls, matched by gender and age. Aims To describe a specific pattern of emotional dysregulation in ED patients. Methods ED patients and the Psychiatric Control Group are recruited at the Institute of Psychiatry in Novara, while healthy controls are recruited on a community basis. All patients and controls are females, aged 18–65. All patients are undergoing the Structured Clinical Interview for DSM-IV -Patient version (SCID-I-P), healthy controls are administered the Structured Clinical Interview for DSM-IV – Non Patient version (SCID-I-NP). All subjects are undergoing the following: SCID-II, Eating Disorder Inventory − 3 (EDI-3), Binge Eating Scale (BES), Beck Depression Inventory (BDI), Symptom Checklist − 90 (SCL-90), Facial Emotion Identification Test (FEIT), The Awareness of Social Inference Test (TASIT), Temperament and Character Inventory (TCI), Rosenberg Self-Esteem Scale (RSES), Interpersonal Reactivity Index (IRI), Toronto Alexithymia Scale (TAS-20). Results The recruitment and analysis of the samples are ongoing. The ED sample is expected to show greater alexythimia and a poorer performance at FEIT and TASIT, compared to the control samples. Conclusions Clinical implications will be discussed.

Higher-order social cognition in first-episode major depression

Patients suffering from major depression experience difficulties in multiple cognitive faculties. A growing body of research has linked affective disorders to abnormalities in social cognition and specifically the processing of discrete emotional stimuli. However, little inquiry has gone into possible impairment in higher-order social cognition including theory of mind, social perception and metacognition. Forty-four medication-naïve patients with first-episode unipolar major depressive disorder and an equal number of matched controls were assessed by the Metacognitive Assessment Scale-Abbreviated (MAS-A), The Frith-Happé animations (FHA) and The Awareness of Social Inference Test (TASIT). Additionally, neurocognition was assessed utilyzing the Cambridge Neuropsychological Test Automated Battery (CANTAB). Depressed patients showed impairment in all domains of higher-order social cognitive ability. Importantly, social cognitive variables retained their inter-group significance after controlling for possible covariates including neurocognition. Results indicate that first-episode depressed patients experience difficulties in all domains of higher-order social cognition including theory of mind, social perception and metacognition.

Older adults' decoding of emotions: age‐related differences in interpreting dynamic emotional displays and the well‐preserved ability to recognize happiness

Although the ability to recognize emotions through bodily and facial muscular movements is vital to everyday life, numerous studies have found that older adults are less adept at identifying emotions than younger adults. The message gleaned from research has been one of greater decline in abilities to recognize specific negative emotions than positive ones. At the same time, these results raise methodological issues with regard to different modalities in which emotion decoding is measured. The main aim of the present study is to identify the pattern of age differences in the ability to decode basic emotions from naturalistic visual emotional displays. The sample comprised a total of 208 adults from Greece, aged from 18 to 86 years. Participants were examined using the Emotion Evaluation Test, which is the first part of a broader audiovisual tool, The Awareness of Social Inference Test. The Emotion Evaluation Test was designed to examine a person's ability to identify six emotions and discriminate these from neutral expressions, as portrayed dynamically by professional actors. The findings indicate that decoding of basic emotions occurs along the broad affective dimension of uncertainty, and a basic step in emotion decoding involves recognizing whether information presented is emotional or not. Age was found to negatively affect the ability to decode basic negatively valenced emotions as well as pleasant surprise. Happiness decoding is the only ability that was found well-preserved with advancing age. The main conclusion drawn from the study is that the pattern in which emotion decoding from visual cues is affected by normal ageing depends on the rate of uncertainty, which either is related to decoding difficulties or is inherent to a specific emotion.

The genetic and neuroanatomical basis of social dysfunction: lessons from neurofibromatosis type 1.

Neurofibromatosis type 1 (NF1) is a common genetic condition associated with cognitive and social dysfunction as well as abnormal brain structure. The pathophysiology underlying social dysfunction in NF1 is poorly understood. Here, we investigate for the first time whether there is a broad deficit of social cognition in NF1 and explore the neural correlates for these deficits. Twenty-nine adults with NF1 and 30 controls were administered an ecologically based test of social cognition, The Awareness of Social Inference Test (TASIT), to identify deficits in emotion recognition and sarcasm detection. We employed voxel-based morphometry in a subset of NF1 patients (n = 16) and 16 additional controls to examine the neural correlates of these deficits. Results indicated that adults with NF1 were impaired in their ability to understand paradoxical sarcasm and their capacity to recognize emotion, particularly anger. TASIT performance was not associated with measures of attention, visuospatial skills or executive function. Relative to controls, gray matter (GM) volume within the right superior temporal gyrus (STG) was decreased, after controlling for total brain volume. Decreased volume in this region was significantly associated with social cognitive deficits in adults with NF1. We conclude that patients with NF1 are at high risk for a social cognitive deficit and provide evidence for a neuroanatomical basis for this deficit; GM volumetric reductions in the right STG. These findings improve our understanding of the nature of social interaction impairments in NF1 and add to the growing body of literature indicating the STG as a critical brain region for social cognition.

Understanding advanced theory of mind and empathy in high-functioning adults with autism spectrum disorder

It has been argued that higher functioning individuals with autism spectrum disorders (ASDs) have specific deficits in advanced but not simple theory of mind (ToM), yet the questionable ecological validity of some tasks reduces the strength of this assumption. The present study employed The Awareness of Social Inference Test (TASIT), which uses video vignettes to assess comprehension of subtle conversational inferences (sarcasm, lies/deception). Given the proposed relationships between advanced ToM and cognitive and affective empathy, these associations were also investigated. As expected, the high-functioning adults with ASDs demonstrated specific deficits in comprehending the beliefs, intentions, and meaning of nonliteral expressions. They also had significantly lower cognitive and affective empathy. Cognitive empathy was related to ToM and group membership whereas affective empathy was only related to group membership.

Assessing Social Cognition and Pragmatic Language in Adolescents with Traumatic Brain Injuries

Traumatic brain injuries (TBI) in children and adolescents can impair social cognition and communication skills but there are few assessment tools suitable for adolescents. The Awareness of Social Inference Test (TASIT) uses professionally enacted audiovisual vignettes of everyday conversational exchanges and is a valid measure of social perception disorders in adults. This study examined its utility for assessing impairments in social cognition in a group of 16 adolescents with TBI, compared to a group of 16 typically developing (TD) adolescents. Adolescents with TBI were, on average, no different to their TD peers on TASIT 1 (emotion recognition) and TASIT 3 (recognizing lies and sarcasm when provided with additional cues) but performed more poorly on TASIT 2 which required them to interpret sarcastic and sincere conversational exchanges with few cues other than the demeanor of the speakers. Within the TBI group, poor performance on TASIT correlated to both relative and self-reported communication difficulties at home. It also correlated with IQ, face recognition and severity of injury as indexed by duration of post-traumatic amnesia. Overall, this study suggests TASIT is a valid measure for adolescents although it raised questions as to how effective normative data is for comparing performance in social cognition during childhood and adolescence.

Exploring sarcasm detection in amyotrophic lateral sclerosis using ecologically valid measures

Amyotrophic lateral sclerosis (ALS) is a rapidly progressive condition involving degeneration of both upper and lower motor neurons. Recent research suggests that a proportion of persons with ALS show a profile similar to that of frontotemporal dementia (FTD), with this group of ALS patients exhibiting social cognitive deficits. Although social cognitive deficits have been partially explored in ALS, research has yet to investigate such changes using ecologically valid measures. Therefore, this study aimed to further characterize the scope of social cognitive and emotion recognition deficits in non-demented ALS patients using an ecologically valid measure of social cognition. A sample of 35 ALS patients and 30 age-and-education matched controls were assessed using the Addenbrooke's Cognitive Examination, the Brixton Spatial Anticipation Test, and The Awareness of Social Inference Test, where participants were required to discriminate between various emotions and decipher socially challenging scenarios enacted in video vignettes. Participants with ALS showed significant difficulties in recognizing both sarcastic and paradoxical sarcastic statements, but not sincere statements, when compared to controls. After controlling for executive difficulties, ALS patients still displayed significant difficulties on tasks that assessed their comprehension of both sarcastic and paradoxical sarcastic statements. The inability to read social cues and make social inferences has the potential to place significant strain on familial/interpersonal relationships in ALS. The findings of this study highlight the importance of employing a broader range of neuropsychological assessment tools to aid in early detection of frontal lobe impairment in non-demented ALS patients.

Adaptive Associations between Social Cognition and Emotion Regulation are Absent in Schizophrenia and Bipolar Disorder

Schizophrenia (SZ) and bipolar disorder (BD) are associated with impairments in facial emotion perception and Theory of Mind (ToM). These social cognitive skills deficits may be related to a reduced capacity to effectively regulate one’s own emotions according to the social context. We therefore set out to examine the relationship between social cognitive abilities and the use of cognitive strategies for regulating negative emotion in SZ and BD. Participants were 56 SZ, 33 BD, and 58 healthy controls (HC) who completed the Ekman 60-faces test of facial emotion recognition; a sub-set of these participants also completed The Awareness of Social Inference Test (TASIT) and the Cognitive Emotion Regulation Questionnaire (CERQ). SZ participants demonstrated impairments in emotion perception on both the Ekman and the TASIT Emotion Evaluation tests relative to BD and HC. While both SZ and BD patients showed ToM deficits (i.e., perception of sarcasm and lie) compared to HC, SZ patients demonstrated significantly greater ToM impairment compared to BD. There were also distinct patterns of cognitive strategies used to regulate emotion in both patient groups: those with SZ were more likely to engage in catastrophizing and rumination, while BD subjects were more likely to blame themselves and were less likely to engage in positive reappraisal, relative to HC. In addition, those with SZ were more likely to blame others compared to BD. Associations between social cognition and affect regulation were revealed for HC only: TASIT performance was negatively associated with more frequent use of rumination, catastrophizing, and blaming others, such that more frequent use of maladaptive cognitive emotion regulation strategies was associated with poor social cognitive performance. These associations were not present in either patient group. However, both SZ and BD patients demonstrated poor ToM performance and aberrant use of emotion regulation strategies consistent with previous studies. SZ also showed basic emotion recognition deficits relative to BD and HC. That there were no associations between social cognition and the capacity to self-regulate negative emotion in SZ and BD (in the context of poor social cognition and maladaptive regulatory strategies) suggests that dysfunction in fronto-limbic brain networks may underpin both social cognitive deficits and the use of maladaptive cognitive strategies in these disorders, albeit by potentially different routes.

Deficits in social perception in opioid maintenance patients, abstinent opioid users and non‐opioid users

This study aimed to compare emotion perception and social inference in opioid maintenance patients with abstinent ex-users and non-heroin-using controls, and determine whether any deficits in could be accounted for by cognitive deficits and/or risk factors for brain damage. Case-control. Sydney, Australia. A total of 125 maintenance patients (MAIN), 50 abstinent opiate users (ABST) and 50 matched controls (CON). The Awareness of Social Inference Test (TASIT) was used to measure emotion perception and social inference. Measures were also taken of executive function, working memory, information processing speed, verbal/non-verbal learning and psychological distress. After adjusting for age, sex, pre-morbid IQ and psychological distress, the MAIN group was impaired relative to CON (β = -0.19, P < 0.05) and ABST (β = -0.19, P < 0.05) on emotion perception and relative to CON (β = -0.25, P < 0.001) and ABST (β = -0.24, P < 0.01) on social inference. In neither case did the CON and ABST groups differ. For both emotion perception (P < 0.001) and social inference (P < 0.001), pre-morbid IQ was a significant independent predictor. Cognitive function was a major predictor of poor emotion perception (β = -0.44, P < 0.001) and social inference (β = -0.48, P < 0.001). Poor emotion recognition was also predicted by number of heroin overdoses (β = -0.14, P < 0.05). Neither time in treatment or type of maintenance medication (methadone or buprenorphine) were related to performance. People in opioid maintenance treatment may have an impaired capacity for emotion perception and ability to make inferences about social situations.

Age-related Differences in Emotion Recognition Ability: Visual and Auditory Modalities

Emotion recognition is an important aspect of social interaction. Deficits in emotion recognition have been tied to poor social competence, interpersonal functioning, and communication along with a reduced quality of life and inappropriate social behavior. Recent experimental evidence suggests that emotion recognition ability across modalities seems to change in an age-dependent way, with deficits specifically noted for negative emotion recognition. Therefore, the primary purpose of this study is to assess emotion recognition ability in both the visual and auditory modalities in healthy elderly patients versus healthy young patients to test the hypothesis that deficits in emotion recognition ability are age-related and increase with age across visual and auditory modalities. The secondary purpose of this study is to assess valence-specific emotion recognition ability to test the hypothesis that increased deficits for elderly individuals as compared to young healthy subjects occur for negative emotion recognition specifically. We examined the ability to recognize emotion in the auditory and visual modality in two groups of patients: healthy elderly subjects and healthy young subjects. The Montreal Affective Voices task (MAV), the Distorted Tunes task (DTT), the Awareness of Social Inference test (TASIT), and the Baron-Cohen Mind in the Eyes Test (EYES) were used to gauge emotion recognition ability. For the visual tasks (TASIT and EYES), the elderly subjects and young subjects did not have significant differences in performance. In addition, a significant difference was also not found for the DTT, indicating that both populations had intact lower-level auditory processing abilities. Significant differences were found between the two populations on the MAV task in both baseline accuracy and valence-specific performance. These findings suggest that age-related deficits in emotion recognition may be specific to the recognition of auditory emotion.

New Frontiers in Neuropsychological Assessment: Assessing Social Perception Using a Standardised Instrument, The Awareness of Social Inference Test

Many clinical disorders lead to impairments in social perception that are not easily detected using standard neuropsychological instruments. In this article, The Awareness of Social Inference Test (TASIT) is described, and evidence for its reliability and validity is reviewed. TASIT was designed to assess the ability to interpret emotional expressions and paralinguistic cues in order to make judgements about speakers' mental states and their conversational meanings, especially when these diverge from the literal meaning of what they say (as in the case of sarcasm). TASIT has three parts: (1) the Emotion Evaluation Test (six basic emotions); (2) Test of Social Inference (Minimal), assessing the ability to understand emotions, mental states, and conversational inferences in sincere and sarcastic interchanges; and (3) Test of Social Inference (Enriched), assessing comprehension of lies and sarcasm, each with alternate forms for re‐testing. TASIT has adequate test–retest and alternate forms reliability. Evidence for construct validity is derived from its relationship to conventional neuropsychological tests, experimental tests of social perception, and real‐world performance. In addition, research using TASIT to examine deficits in social perception in traumatic brain injury, schizophrenia, frontotemporal dementia, Alzheimer's disease, and stroke attest to its sensitivity as a clinical assessment tool.

Comprehension of insincere communication in neurodegenerative disease: Lies, sarcasm, and theory of mind

Comprehension of insincere communication is an important aspect of social cognition requiring visual perspective taking, emotion reading, and understanding others’ thoughts, opinions, and intentions. Someone who is lying intends to hide their insincerity from the listener, while a sarcastic speaker wants the listener to recognize they are speaking insincerely. We investigated whether face-to-face testing of comprehending insincere communication would effectively discriminate among neurodegenerative disease patients with different patterns of real-life social deficits. We examined ability to comprehend lies and sarcasm from a third-person perspective, using contextual cues, in 102 patients with one of four neurodegenerative diseases (behavioral variant frontotemporal dementia [bvFTD], Alzheimer’s disease [AD], progressive supranuclear palsy [PSP], and vascular cognitive impairment) and 77 healthy older adults (normal controls – NCs). Participants answered questions about videos depicting social interactions involving deceptive, sarcastic, or sincere speech using The Awareness of Social Inference Test. All subjects equally understood sincere remarks, but bvFTD patients displayed impaired comprehension of lies and sarcasm compared with NCs. In other groups, impairment was not disease-specific but was proportionate to general cognitive impairment. Analysis of the task components revealed that only bvFTD patients were impaired on perspective taking and emotion reading elements and that both bvFTD and PSP patients had impaired ability to represent others’ opinions and intentions (i.e., theory of mind). Test performance correlated with informants’ ratings of subjects’ empathy, perspective taking and neuropsychiatric symptoms in everyday life. Comprehending insincere communication is complex and requires multiple cognitive and emotional processes vulnerable across neurodegenerative diseases. However, bvFTD patients show uniquely focal and severe impairments at every level of theory of mind and emotion reading, leading to an inability to identify obvious examples of deception and sarcasm. This is consistent with studies suggesting this disease targets a specific neural network necessary for perceiving social salience and predicting negative social outcomes.

Social cognition in schizophrenia, Part 1: performance across phase of illness.

Social cognitive impairments are consistently reported in schizophrenia and are associated with functional outcome. We currently know very little about whether these impairments are stable over the course of illness. In the current study, 3 different aspects of social cognition were assessed (emotion processing, Theory of Mind [ToM], and social relationship perception) at 3 distinct developmental phases of illness: prodromal, first episode, and chronic. In this cross-sectional study, participants included 50 individuals with the prodromal risk syndrome for psychosis and 34 demographically comparable controls, 81 first-episode schizophrenia patients and 46 demographically comparable controls, and 53 chronic schizophrenia patients and 47 demographically comparable controls. Outcome measures included total and subtest scores on 3 specialized measures of social cognition: (1) emotion processing assessed with the Mayer-Salovey-Caruso Emotional Intelligence Test, (2) ToM assessed with The Awareness of Social Inference Test, and (3) social relationship perception assessed the Relationships Across Domains Test. Social cognitive performance was impaired across all domains of social cognition and in all clinical samples. Group differences in performance were comparable across phase of illness, with no evidence of progression or improvement. Age had no significant effect on performance for either the clinical or the comparison groups. The findings suggest that social cognition in these 3 domains fits a stable pattern that has outcome and treatment implications. An accompanying article prospectively examines the longitudinal stability of social cognition and prediction of functional outcome in the first-episode sample.
