Mindreading abilities in sexual offenders: an analysis of theory of mind processes

The paper aims to assess the theory of mind (ToM) of sexual offenders. We administered to 21 sexual offenders and to 21 nonoffenders two classical first- and second-order ToM tasks, a selection of six Strange Stories, and a semi-structured interview, the Theory of Mind Assessment Scale (Th.o.m.a.s), which provides a multi-dimensional evaluation of ToM, investigating first- vs. third-person and egocentric vs. allocentric perspectives. Results show that sexual offenders performed worse than controls on second-order ToM tasks, on Strange Stories and on each of the Th.o.m.a.s dimensions, whereas they did as well as the control group on first-order ToM tasks. A detailed analysis of participants’ performance on Th.o.m.a.s. showed that sex offenders performed worse on the third-person than on the first-person ToM scale, and worse on the allocentric than on the egocentric perspective; these findings did not apply to the controls. Implications for future research and treatment are discussed.     

A broad assessment of theory of mind in adolescence: The complexity of mindreading

The aim of this research was to provide an articulated assessment of several different ToM components, namely first- vs. third-person, egocentric vs. allocentric, and first- vs. second-order ToM, in preadolescence and adolescence. Our expectations for the sample of 80 juveniles that participated in the research were that: (1) ToM abilities would improve with age; (2) participants would perform better at first-person than at third-person tasks; (3) participants would perform better at first-order than at second-order tasks; (4) girls will perform systematically better than boys. We also explored possible differences in performance (5) in the allocentric vs. the egocentric perspectives as well as (6) in the comprehension of different types of mental states, namely desires, beliefs and positive and negative emotions. Overall our expectations were confirmed. Our data confirmed that all ToM aspects we investigated keep maturing during preadolescence and adolescence.     

Theory of Mind Deficit in Schizophrenia and Associated Cognitive Functions

This study examined the Theory of Mind (ToM) ability of schizophrenic persons in association with other cognitive functions like memory, executive functioning and attention. Results showed evidence of relationship between ToM and cognitive functions i.e. executive function, working memory and intelligence but no uniform predictive model was found across all the ToM tasks. It was also noted that predicting variables related to different cognitive domains varied markedly for schizophrenia and control groups. It seems that there are multiple cognitive pathways to ToM mechanism, although these different forms may not have an additive effect.     

Theory of Mind in schizophrenia: first person vs third person perspective

Patients suffering from schizophrenia have an impaired meta-representation also known as Theory of Mind (ToM). Moreover, the presence of delusions or other positive symptoms of schizophrenia has been correlated to poor ToM performances. Lack of insight is a common symptom of schizophrenia and can be considered a critical manifestation of impaired ToM abilities. In particular, the present study addresses the role of perspective ToM ability in schizophrenic patients. Thirty severely delusional schizophrenic patients completely lack insight when interviewed about their delusions. Seven subsequently gain insight about their mental state when perspective is shifted from the first person to third person. These data suggest that in some delusional schizophrenic patients, it may be possible to gain access to and modify their mental states.     

Theory of Mind in Patients with Epilepsy: a Systematic Review and Meta-analysis

The ability to understand our own thoughts, intentions, beliefs and emotions and those of others (Theory of Mind; ToM) is a high-order social cognitive skill that is vital for social interaction and which has been found to be impaired in patients with epilepsy. Studies examining ToM in patients with epilepsy, however, have yielded inconsistent findings. The main aim of this study is to determine whether the magnitude of ToM deficits varies as a function of the site of epilepsy focus and/or the type of ToM task used. Electronic databases searches included Psychinfo, Medline/PubMed and EMBASE. Studies were included if they examined a group of patients with epilepsy and a group of healthy controls, reported original research, were published in the English language in peer reviewed journals, and used one of five empirically validated measures of ToM: False Belief, Reading the Mind in the Eyes Task (RMET), Faux-pas, Strange Stories, Cartoon ToM vignettes. Twelve studies were identified, ten included adults and two included children with epilepsy. Findings revealed marked ToM deficits in adults with focal seizures emanating from core brain regions underpinning ToM: temporal and frontal lobes (frontal lobe epilepsy, FLE; temporal lobe epilepsy, TLE), but not in adults with focal seizures outside the temporal and frontal lobes (extra-TLE/FLE). ToM deficits were also observed in children with generalised seizures (idiopathic generalised epilepsy, IGE). ToM deficits were documented across ToM tasks. In conclusion, ToM deficits represent a robust finding in adults with frontal and temporal epilepsy, but are also found in children with generalised seizures. Further research into ToM is needed, especially in children with epilepsy as early ToM may have cumulative, negative effects on development of social skills that continues into adulthood.     

儿童的分配公平性:心理理论的作用

心理理论是影响儿童分配公平性的重要因素之一。"多重动机"的理论假设认为心理理论能够帮助儿童在不同的动机中权衡利弊,找到满足自我利益和他人需求之间的平衡;其中,感知需求、推断意图、理解情绪是影响独裁者博弈、最后通牒博弈、第三方惩罚中分配公平性的主要成分。未来研究需为此提供更多实证依据,探讨不同类型的公平分配与心理理论各组成成分的关系,以及可否通过训练心理理论能力促进儿童公平概念的发展。     

The Relation Between Children's Trust Beliefs and Theory of Mind Abilities

The study examined the relation between children's trust beliefs and Theory of Mind (ToM) abilities. A sample of 168 Italian children (M = 9 years–6 months, SD = 7 months) were administered the Italian Children's Generalized Trust Beliefs (ICGTB) Scale, two Second‐Order False Belief ToM measures, and an Advanced ToM measure. As expected, the ICGTB scale demonstrated: (1) validity by its three factor structure and (2) reliability by exhibiting acceptable internal consistency and test–retest stability. As expected, the children's emotional trust beliefs in others were associated with both second‐order false belief ToM ability and advanced ToM ability. These relations were not attributable to verbal ability. The findings are discussed with respect to the relations among children's emotional trust beliefs, personal disclosure, and quality of attachment. Copyright © 2014 John Wiley & Sons, Ltd.     

Cognitive contributions to theory of mind ability in children with a traumatic head injury

The objective of the current study is to examine the contribution of intellectual abilities, executive functions (EF), and facial emotion recognition to difficulties in Theory of Mind (ToM) abilities in children with a traumatic head injury. Israeli children with a traumatic head injury were compared with their non-injured counterparts. Each group included 18 children (12 males) ages 7–13. Measurements included reading the mind in the eyes, facial emotion recognition, reasoning the other’s characteristics based on motive and outcome, Raven’s Coloured Progressive Matrices, similarities and digit span (Wechsler Intelligence Scale for Children – Revised 95 subscales), verbal fluency, and the Behaviour Rating Inventory of Executive Functions. Non-injured children performed significantly better on ToM, abstract reasoning, and EF measures compared with children with a traumatic head injury. However, differences in ToM abilities between the groups were no longer significant after controlling for abstract reasoning, working memory, verbal fluency, or facial emotion recognition. Impaired ToM recognition and reasoning abilities after a head injury may result from other cognitive impairments. In children with mild and moderate head injury, poorer performance on ToM tasks may reflect poorer abstract reasoning, a general tendency to concretize stimuli, working memory and verbal fluency deficits, and difficulties in facial emotion recognition, rather than deficits in the ability to understand the other’s thoughts and emotions. ToM impairments may be secondary to a range of cognitive deficits in determining social outcomes in this population.     

Mind Reading Skills and Empathy: Evidence for Nice and Nasty ToM Behaviours in School-Aged Children

We investigated the social use of theory of mind in school-aged children. The expressions Nice Theory of Mind and Nasty Theory of Mind are used to differentiate behaviours requiring a prosocial use and an antisocial use of ToM abilities respectively. Our goals was to investigate whether and how mind reading abilities and empathy affect nice and nasty ToM behaviours. One hundred and ninety-seven children who were fourth and fifth graders took part in this study. Participants were administered stories that assessed cognitive, affective or moral mental state reasoning abilities and they also completed a self-report measure of empathy. Teachers’ rating on children’s prosocial and antisocial behaviours that underpin ToM abilities led us to identify nice and nasty ToM behaviours. We found that children who engage in nasty ToM behaviour showed good abilities to understand others’ thoughts and beliefs. However, children with nice ToM behaviour showed more moral and emotional sensitivity as compared to children who engage in nasty ToM behaviour. Furthermore, the hot component of empathy is stronger in fostering prosocial behaviours and inhibiting antisocial acts than cognitive component.     

Theory of mind in non-suicidal self-injury (NSSI) adolescents

The aim of the present study is to investigate different facets of the theory of mind (ToM), i.e. first vs. third-person, first vs. second-order ToM, egocentric vs. allocentric perspective, in a clinical sample of 20 non-suicidal self-injury (NSSI) adolescent inpatients and 20 healthy controls.Methods: We investigated whether performance in ToM tasks was related to both the type and frequency of self-injuring behavior and attitude toward life and death, using a semi-structured interview and different self-report questionnaires.Results: NSSI participants performed less well than the control group in all the ToM dimensions investigated. Furthermore, ToM performance was negatively related to Attraction to Death, in terms of both the type and frequency of self-injuring behavior, and it was positively related to Attraction to Life.Conclusions: These preliminary findings have interesting implications for future clinical investigations, in that they provide previously unavailable information regarding the association between ToM and NSSI behavior.     

Executive and attentional contributions to Theory of Mind deficit in attention deficit/hyperactivity disorder (ADHD)

Attention deficit/hyperactivity disorder (ADHD) in children has been associated with attentional and executive problems, but also with socioemotional difficulties possibly associated with deficits in Theory of Mind (ToM). Socioemotional problems in ADHD are associated with more negative prognoses, notably interpersonal, educational problems, and an increased risk of developing other psychiatric disorders that emphasize the need to clarify the nature of their ToM deficits. In this study, we hypothesized that ToM dysfunction in children with ADHD is largely attributable to their attentional and/or executive deficits. Thirty-one children with ADHD (8–12 years, IQ > 85) and 31 typically developing (TD) children were assessed using executive functions (inhibition, planning, and flexibility) and attentional tasks, as well as two advanced ToM tasks (Reading the Mind in the Eyes and Faux Pas) involving different levels of executive control. Children with ADHD performed more poorly than TD children in attentional, executive function, and ToM tasks. Linear regression analyses conducted in the ADHD group indicated that inhibition scores predicted performance on the “Faux Pas” task the best, while attention scores were the best for predicting performance on the Reading the Mind in the Eyes task. When controlled for inhibition and attentional variables, ToM performance in children with ADHD was actually similar to TD children. Contrarily, controlling for ToM scores did not normalize performance for inhibition and attentional tasks in children with ADHD. This unidirectional relationship suggests that deficits in the EF and attentional domains are responsible for ToM deficits in ADHD, which therefore may contribute to their socioemotional difficulties.     

An exploratory assessment of theory of mind and psychological impairment in patients with bulimia nervosa

This study aimed to investigate psychosocial functioning and different dimensions of theory of mind (ToM) in people with bulimia nervosa (BN) and Eating Disorder Not Otherwise Specified‐BN type (EDNOS‐BN). Psychosocial functioning and ToM were assessed in a sample of young adult females, 16 BN and 16 EDNOS‐BN outpatients and 16 healthy controls (HCs). They were assessed using the Eating Disorder Inventory‐Symptom Checklist‐2 (EDI‐2 SC) for evaluating psychological traits associated with eating disorders; the Symptom Checklist‐90‐Revised (SCL‐90‐R) for evaluating psychopathological status; and the Theory of Mind Assessment Scale (Th.o.m.a.s.), a semi‐structured interview aimed at assessing a person's different dimensions of ToM. The BN and EDNOS‐BN groups exhibited worse performance than the control group on all dimensions of the SCL‐90‐R, and on all dimensions of the EDI‐2 SC. The only difference for perfectionism was that BN obtained higher scores than EDNOS‐BN group. Our results also revealed an impairment of third‐person and second‐order ToM in patients with bulimia (BN and EDNOS‐BN) with respect to control subjects. These preliminary data have important implications for future empirical work, in that they provide valuable information regarding the importance of investigating the various facets of ToM ability separately, in order to provide a more detailed profile of ToM functioning in the clinical samples.     

Cognitive and affective Theory of Mind in mild to moderate Alzheimer's disease

Theory of Mind (ToM) allows one's own and others' cognitive and emotional mental states to be inferred. Although many patients with Alzheimer's disease (AD) display impaired social functioning as their disease progresses, very few studies have investigated ToM in AD. Those that have done so suggest that patients' ToM deficits are the consequence of other cognitive impairments. The aim of this study was thus to investigate changes in both the cognitive and the affective dimensions of ToM in AD, using tasks designed to circumvent the patients' comprehension difficulties. Sixteen mild to moderate AD patients and 15 healthy controls matched on age, sex and education level underwent cognitive (preference judgment and first‐ and second‐order false belief) and affective (Reading the Mind in the Eyes) ToM assessments. Comprehension of false belief stories was verified and an additional neuropsychological examination was undergone. We observed impaired performances by AD patients on all the ToM tasks. While working memory and executive functioning impairments contributed to the deterioration in the more complex aspects of cognitive ToM abilities as highlighted by a correlation analysis, we failed to observe any comprehension difficulties in patients who performed poorly on simple cognitive ToM tasks, which suggests that AD truly affects cognitive ToM.     

Development of the Basel Version of the Awareness of Social Inference Test – Theory of Mind (BASIT-ToM) in healthy adults

Impairments of Theory of Mind (ToM) abilities occur in a wide range of brain disorders. Therefore, reliable and ecologically valid examination of these abilities is a crucial part of any comprehensive neuropsychological assessment. An established and ecologically valid, English-language test identifying deficits in ToM abilities is “The Awareness of Social Inference Test – Social Inference Minimal (TASIT-SIM)”. However, no comparable German-language ToM test currently exists. In this study, we aimed to develop the first German-language adaption of TASIT-SIM in healthy adults. We selected 13 scenes [four scenes per message type (i.e., honesty, simple sarcasm, paradoxical sarcasm) and one practice scene] out of the 30 TASIT-SIM scenes. In collaboration with a film institute, we filmed each scene at three different intensities. These intensity version scenes were then administered to 240 healthy adults, equally distributed in sex and age, ranging from 35 to 92 years. By applying Rasch analysis, we selected intensity versions that showed neither floor nor ceiling effects in the majority of ToM questions in participants whose ToM abilities were in the medium range. In conclusion, we have developed the first German-language adaption of TASIT-SIM, i.e., the “Basel Version of the Awareness of Social Inference Test – Theory of Mind (BASIT-ToM)”. The BASIT-ToM incorporates the strengths of TASIT-SIM, while overcoming its limitations such as inconsistencies in cinematic realization and ceiling effects in healthy participants. Next, the BASIT-ToM needs to be validated in healthy people and clinical populations.     

Parent-report measure of Theory of Mind: Adaptation to Polish of the Children’s Social Understanding Scale

The main aim of the study was to investigate whether the Children’s Social Understanding Scale (CSUS), a parent report technique, is a valid and reliable measure of Theory of Mind (ToM) abilities in Polish-speaking children. Additionally, the role of language abilities in ToM development was explored. A group of 225 parents of approximately 3.5-year-old Polish children was tested using the Polish version of the CSUS. Their children were tested with a word comprehension test and five behavioural ToM tasks. Satisfactory psychometric properties of the Polish CSUS were observed and positive correlations between the CSUS and behavioural ToM tasks were found. A two-factor structure was found in the CSUS: Mental State Talk (MST) and Mental State Comprehension. The MST factor was significantly related to word comprehension. The utility of the Polish version of the CSUS for future cross-cultural research with this population is discussed.     

The role of control functions in mentalizing: dual-task studies of theory of mind and executive function

Conflicting evidence has arisen from correlational studies regarding the role of executive control functions in Theory of Mind. The current study used dual-task manipulations of executive functions (inhibition, updating and switching) to investigate the role of these control functions in mental state and non-mental state tasks. The 'Eyes' pictorial test of Theory of Mind showed specific dual-task costs when concurrently performed with an inhibitory secondary task. In contrast, interference effects on a verbal 'Stories' task were general, occurring on both mental state and non-mental state tasks, and across all types of executive function. These findings from healthy functioning adults should help to guide decisions about appropriate methods of assessing ToM in clinical populations, and interpreting deficits in performance in such tasks in the context of more general cognitive dysfunction.     

Domain-specificity and theory of mind: evaluating neuropsychological evidence

Humans' unique aptitude for reasoning about mental states, known as Theory of Mind (ToM), can help explain the unique character of human communication and social interaction. ToM has been studied extensively in children, but there is no clear account of the cognitive basis of ToM in adults. Evidence from functional imaging and neuropsychology is beginning to address this surprising gap in our understanding, and this evidence is often thought to favour a domain-specific or modular architecture for ToM. We present a systematic approach to this issue for the paradigmatic case of belief reasoning, and argue that neuropsychological data provide no clear evidence for domain-specificity or modularity. Progress in understanding ToM requires new tasks that isolate potentially distinct components of this complex ability.     

Theory of mind ability in high socially anxious individuals

Background/Objectives: Research has demonstrated an association between social anxiety and impaired Theory of Mind (ToM). We assess whether ToM deficits occur even at a subclinical level of social anxiety and whether group differences in ToM performance are consistent with interpretation bias. We also explore potential reasons as to why socially anxious individuals may perform differently on ToM tasks.

Methods/Design: Undergraduate participants high (HSA; n?=?78) and low (LSA; n?=?35) in social anxiety completed a task of ToM decoding, the Reading the Mind in the Eyes (MIE), a task of ToM reasoning, the Movie for the Assessment of Social Cognition (MASC), and a post-task questionnaire about their experience completing the MASC.

Results: HSAs performed marginally worse than LSAs on the MIE on neutrally valenced trials, and their pattern of errors may be consistent with a negative interpretation bias. HSAs and LSAs did not differ overall in performance on the MASC, though HSAs reported experiencing more confusion and distress than LSAs during the task, and this distress was associated with more MASC errors for HSA participants only. These results provide insight into the nature of ToM ability in socially anxious individuals and highlight important avenues for future research.     

Factorial structure of the ‘ToM Storybooks’: A test evaluating multiple components of Theory of Mind

This study examined the factorial structure of the Theory of Mind (ToM) Storybooks, a comprehensive 93‐item instrument tapping the five components in Wellman's model of ToM (emotion recognition, understanding of desire and beliefs, ability to distinguish between physical and mental entities, and awareness of the link between perception and knowledge). A sample of 681 three‐ to eight‐year‐old Italian children was divided into three age groups to assess whether factorial structure varied across different age ranges. Partial credit model analysis was applied to the data, leading to the empirical identification of 23 composite variables aggregating the ToM Storybooks items. Confirmatory factor analysis was then conducted on the composite variables, providing support for the theoretical model. There were partial differences in the specific composite variables making up the dimensions for each of the three age groups. A single test evaluating distinct dimensions of ToM is a valuable resource for clinical practice which may be used to define differential profiles for specific populations.
