Age-Related Changes in Theory of Mind in Middle Childhood: A Cross-Cultural Comparison Between Australian and Chinese Children

To date, cross-cultural studies on Theory of Mind (ToM) have predominantly focused on preschoolers. This study focuses on middle childhood, comparing two samples of mainland Chinese (n = 126) and Australian (n = 83) children aged between 5.5 and 12 years. Strange Stories, the most commonly used measure of ToM, was employed. The study aimed to examine the one- versus two-factor structure and measurement invariance of Strange Stories across two cultures; use the verified invariant model of Strange Stories to compare children’s cognitive and affective ToM across two cultures; and finally, to investigate correlates of individual differences on Strange Stories cross-culturally. Multiple-groups confirmatory factor analysis revealed the measurement invariance of a two-factor model of Strange Stories (cognitive and affective) in both groups. Chinese children performed comparably to Australian children on cognitive ToM stories, but more poorly than Australian children on affective ToM stories. There were cultural differences in the correlates of ToM. The number of older siblings was a positive predictor of cognitive ToM for Chinese children, but a negative predictor of cognitive ToM for Australian children. The findings confirm that Strange Stories is a reliable measure for evaluating ToM in school-aged children from mainland China and Australia and highlight the importance of considering both cognitive and affective aspects of ToM in cross-cultural comparison.

The impact of executive dysfunctions on Theory of Mind abilities in Parkinson's disease

Theory of mind (ToM) is the ability to understand and interpret another person's beliefs, intentions (cognitive ToM) and emotions (affective ToM). To explore affective and cognitive ToM and their neuropsychological correlates in patients affected by multiple sclerosis (MS). Forty MS patients and 40 matched control individuals underwent tasks assessing cognitive (the ToM Pictures Sequencing Task and the Advanced Test of ToM) and affective ToM (the Reading the Mind in the Eyes Task and the Emotion Attribution Task), in both verbal and nonverbal modality, a comprehensive neuropsychological battery, and questionnaires for behavioral disorders. MS patients performed significantly worse than controls on tasks assessing cognitive and affective ToM, in verbal and nonverbal modality. Moreover, MS patients achieved significantly lower scores on tests assessing visuospatial learning and speed of spatial information processing, and significantly higher scores on scales for alexithymia and depression with respect to controls. After covarying for cognitive and behavioral variables different in the 2 groups, the differences between patients and controls on ToM tasks remained significant. ToM abilities were significantly related to executive functions, but not to depressive, anxious and apathetic symptoms. Higher alexithymia scores were associated with poor recognition of others' mental states. The findings demonstrated that both affective and cognitive aspects of ToM are impaired in nondemented and mildly to moderately disabled MS and suggest that impaired social cognition can occur independently from behavioral disorders.

Background Theory of Mind (ToM), the ability to infer others’ mental states, is central to social interaction and may be sensitive to age-related differences. This study explored variations in cognitive and affective ToM across adulthood and examined the roles of executive functions (EFs), general cognition, and Cognitive Reserve (CR). Methods Ninety-six participants were assigned to three groups: Young Adults (20–40), Older Adults (65–75), and Senior Older Adults (76–86). Cognitive ToM was assessed with the Strange Stories and II Order Stories tasks, and affective ToM with the Reading the Mind in the Eyes Test. Measures of processing speed, working memory, long-term memory, EFs (updating, shifting, inhibition), and CR were included. Results Both cognitive and affective ToM varied by age group, with younger adults performing better than older groups. Updating and shifting predicted ToM performance, accounting for group differences in cognitive ToM and partially in affective ToM. CR, particularly occupational activity, moderated the association between age group and cognitive ToM: differences emerged at low CR but not at high CR levels. Conclusions Findings suggest that age-related differences in ToM are associated with executive functioning and that higher CR may mitigate these differences, supporting the role of cognitive engagement in social-cognitive maintenance.

BackgroundEvidence in the literature suggests that there is an impairment of social cognition in schizophrenia. Theory of Mind (ToM) is defined as one’s ability to understand others’ wishes, beliefs, intentions, and other psychological states and thereby to judge others’ behavior, as an essential component of social cognition. However, there have been limited studies on social cognition, especially ToM in adolescent onset schizophrenia (AOS). The current study aims to investigate ToM abilities in adolescent schizophrenia according to various ToM subcomponents (cognitive ToM and affective ToM) and various ToM orders (first order and second order).MethodsThis study examines ToM in 35 adolescent schizophrenic patients and 35 healthy adolescents using the “Yoni task” and “Faux Pas Recognition test” to assess their affective and cognitive ToM abilities.ResultsIn the Yoni task, patients with AOS showed differences in ToM abilities either on a different order or under different conditions. The Faux Pas Recognition task results revealed that AOS patients were not always able to recognize a faux pas or understand complicated emotions under the faux pas scenario. Furthermore, as indicated by the correlation analysis, neither cognitive ToM nor affective ToM was related to the patients’ symptoms, disease duration, dose of medication, or intelligence quotient (IQ).ConclusionOur findings showed AOS impairment in the performance of ToM tasks. It seemed that impairment in second-order-ToM is more serious. Moreover, these deficits are largely independent of symptom clusters, disease duration, dose of medication, and IQ. It can be speculated that ToM dysfunction may be a hallmark of adolescent schizophrenia.

Affective and cognitive theory of mind in patients with parkinson’s disease

Theory of mind (ToM) deficits have been reported in persons with multiple sclerosis (pwMS). However, most studies have used pictures or written scenarios as stimuli without distinguishing between cognitive and affective ToM, and no studies have investigated older pwMS. We recruited 13 young healthy controls (HC), 14 young pwMS, 14 elderly HC and 15 elderly pwMS. ToM was measured using an adaptation of the Conversations and Insinuations task (Ouellet et al., J. Int. Neuropsychol. Soc., 16, 2010, 287). In this ecological video‐based task, participants watch four 2‐minute videos of social interactions, which are interrupted by multiple choice questions about either the emotional state (affective ToM) or the intention (cognitive ToM) of the characters. They also underwent a short neuropsychological battery including cognitive, executive and social cognition tasks and questionnaires. We observed a significant interaction between the ToM conditions and the groups regarding ToM performance. Elderly pwMS scored significantly lower than elderly HC and young pwMS in cognitive ToM, but not in affective ToM. They also showed the largest discrepancy between their cognitive and affective ToM. Young pwMS showed relatively preserved ToM in both conditions. Both cognitive and affective ToM correlated with global cognition and executive abilities, but not with social cognitive measures (emotion recognition, real‐life empathy). This study suggests that decline in cognitive ToM might be accentuated by advancing age in pwMS. These impairments are most likely underlied by cognitive and executive difficulties, but not by core social cognitive impairments. Future studies should investigate the real‐life impacts of ToM impairments in pwMS.

Background: Several meta-analyses highlight pronounced problems in general Theory of Mind (ToM), the ability to infer other persons' mental states, in patients with psychosis in comparison to non-clinical controls. In addition, first studies suggest associations between Hyper-ToM, an exaggerated inference of mental states to others, and delusions. Research on different ToM subtypes (Cognitive ToM, Affective ToM, and Hyper-ToM) and symptom clusters of psychosis (positive, negative, and disorganized symptoms) have gathered conflicting findings. Thus, the present study examined group differences between patients with psychosis and non-clinical controls concerning Cognitive ToM/Affective ToM and Hyper-ToM. Further, the association between ToM subtypes and symptom clusters (positive, negative, and disorganized symptoms) were examined.Methods: Patients with psychotic disorders (n = 64, 1/3 with present delusions indicated by a minimum score of four in the PANSS P1 item) and non-clinical controls (n = 21) were examined with assessments of Cognitive ToM and Affective ToM abilities and Hyper-ToM errors using the Frith-Happé animations. Psychopathology was assessed using the Positive and Negative Syndrome Scale.Results: Patients with psychosis presented more pronounced problems in Cognitive and Affective ToM in comparison to non-clinical controls, whereas there were no group differences with regard to Hyper-ToM errors. Furthermore, deficits in Cognitive ToM were associated with general delusions, whereas problems in Affective ToM were associated with negative and disorganized symptoms. In addition, there was no association between Hyper-ToM errors and any symptoms when controlling for years of education.Conclusions: Our findings suggest that deficits in ToM subtypes might not be directly related to delusions and positive symptoms and are in line with more recently developed cognitive models of delusions. In addition, our results support the well-established finding of associations between ToM alterations and negative or disorganized symptoms. Our results shed light on the role of different dimensions of ToM in specific symptoms of psychosis.

EPA-0988 – Cognitive and affective theory of mind in schizophrenia and euthymic bipolar disorder

Social cognitive deficits are an important consequence of multiple sclerosis (MS), yet our understanding of how these deficits manifest in progressive MS is currently limited. To this end, we examined theory of mind (ToM) ability in a sample of individuals with progressive MS using an ecologically valid virtual assessment tool that allows for delineation of cognitive ToM (inferring thoughts and intentions of others) from affective ToM (inferring emotions of others). We compared 15 individuals with progressive MS and 15 healthy controls on their ToM ability using the Virtual Assessment of Mentalising Ability. We found that, relative to healthy controls, participants with progressive MS were impaired in cognitive ToM, but not in affective ToM. Furthermore, we found that the MS participants' deficits in cognitive ToM were mediated by their general cognitive ability such that poor cognitive ToM ability in MS was explained by poor performance on tests of memory and processing speed. Our findings demonstrate that ToM deficits in progressive MS may be limited to cognitive ToM, while affective ToM is conserved. This could be attributable to the MS-related deficits in general cognitive ability, which appear to negatively affect only the cognitive component of ToM.

Previous studies that focused on age-related changes in the performance of theory of mind (ToM) in older adults have provided conflicting results. ToM consists of cognitive and affective mentalizing processes. Mixed calculation of different aspects of ToM may have contributed to the conflicting results and fails to detect the specific age effects on ToM. The current study investigated the age-related changes on stories tasks that specifically assess cognitive versus affective ToM in 42 young-old adults and 32 old-old adults, compared to 32 young adults. A factor analysis revealed that the ToM stories tasks could be classified into three components. Both of the two older adult groups performed worse than young adult group on cognitive ToM stories tasks (p < .001). However, older adults performed nearly the same as young adults on affective ToM stories tasks (p > .05). Moreover, performance on executive inhibition, measured by the Hayling test, was only correlated with cognitive ToM tasks (β = -0.318, R2 = 0.101), but not with affective ToM tasks. The results reveal a greater age effect on cognitive compared to affective ToM. Rather than a general decline of ToM, older adults show selective compromised performance on cognitive ToM tasks, while relatively intact performance on affective ToM stories tasks. The dissociable correlation between cognitive versus affective ToM with inhibitive control further confirms the dissociation of cognitive and affective ToM.

Theory of Mind (ToM) is the ability to represent and attribute mental states to oneself and others. So far, research regarding ToM processing across adolescence is scarce. Existing studies either yield inconsistent results or did not or not thoroughly investigate aspects like higher order ToM and associated neuropsychological variables which the current study tried to address. 643 typically developing early, middle, and late adolescents (age groups 13–14; 15–16; 17–18) performed cognitive and affective ToM tasks as well as neuropsychological tasks tapping the cognitive or affective domain. Regarding both ToM types, 15- to 16-year-olds and 17- to 18-year-olds outperformed 13- to 14-year-olds, whereas females were superior regarding cognitive ToM. Across adolescence, cognitive and affective ToM correlated with attention and affective intelligence, whereas working memory, language comprehension, and figural intelligence additionally correlated with cognitive ToM. In early adolescence, attention correlated with both ToM types, whereas cognitive ToM further correlated with language comprehension and affective ToM with verbal intelligence, verbal fluency, and verbal flexibility. In middle and late adolescence, affective intelligence correlated with both ToM types, whereas cognitive ToM additionally correlated with working memory, language comprehension, and figural intelligence. The current study shows a developmental step regarding cognitive and affective ToM in middle adolescence as well as gender differences in cognitive ToM processing. Associations between neuropsychological variables and ToM processing were shown across adolescence and within age groups. Results give new insights into social cognition in adolescence and are well supported by neuroscientific and neurobiological studies regarding ToM and the integration of cognitive and affective processes.Graphic abstract

ABSTRACTBackground/Study Context: Theory of Mind (ToM) reflects the ability to reason about mental states in order to understand and predict behavior. Research has identified links between increased pulse pressure, a measure of vascular health, and reduced cognitive ToM in older adults. However, the relationships between other vascular and nonvascular conditions and reduced ToM are unknown. We examined (1) illnesses as predictors of cognitive and affective ToM and (2) neurocognitive mediators of illness burden and ToM. Methods: We used hierarchical regression and mediation to investigate the effects of vascular illness burden (hypertension, Type 2 diabetes, high cholesterol, and high pulse pressure) and nonvascular illness burden (osteoporosis, osteoarthritis, rheumatoid arthritis, and thyroid dysfunction) on cognitive and affective ToM in N = 86 community-dwelling older adults (59 females; 27 males, M age = 71.74 years). Results: Vascular illness burden emerged as a significant predictor of older adults’ cognitive ToM (R2 = .43, p < .001), and this relationship was mediated by executive functioning. Nonvascular illness burden did not predict cognitive nor affective ToM in this sample. Conclusion: Our findings highlight the specific importance of considering vascular health as a risk factor for declines in ToM in later life. Further elucidation of the associations between health, neurocognition, and ToM will be valuable in developing effective interventions for older adults given the high prevalence of vascular illness in later life.

Objective: This study aimed to investigate the theory of mind (ToM) understanding in early implanted school-aged children in Norway, comparing their performance to that of typically developing (TD) peers, and considering age at implantation and hearing age. Methods: Twelve 8–12-year-old children, who received cochlear implants (CI) before 18 months of age, were recruited. Ten of them were included in early speech-language and listening intervention. The control group comprised 22 TD peers. All children underwent tests evaluating cognitive and affective ToM. Bayesian methods were used to examine group differences in cognitive and affective ToM, and the relationships between ToM variables and implantation and hearing age. Results: The children with CI were more likely to perform comparably to TD peers on both affective and cognitive ToM, than differing from them. The relationship between affective ToM and implantation age was more likely to be present than absent, while a converse correlation pattern was found for cognitive ToM and implantation and hearing age. The relationship between affective ToM and hearing age was inconclusive, suggesting more data is needed. Conclusion: Our findings underscore the importance of early implantation in supporting ToM progress, aligning with the sensitive period account. Missing the sensitive period for optimal ToM development could lead to lasting ToM developmental gaps. Therefore, to minimize potential delays, it might be essential to provide CI and speech-language and listening intervention early in life. These measures facilitate the social interactions with caregivers that are critical for fostering ToM development.
