Theory of Mind (ToM) is compromised in schizophrenia, and responsible for social disability. We aim to study the correlation between ToM deficits and Executive Functions (EF), using the Faux Pas Test (FPT) for ToM evaluation, Behavioral Assessment of the Dysexecutive Syndrome (BADS) and Wisconsin Card Sorting Test (WCST) for EF assessment. Two groups of patients with schizophrenia were included: 22 young (18-35 years-old) and 18 middle-aged (>50 years-old) Patients, compared to age-matched Controls. We found worst FPT performances in both groups of patients, but with a more generalized pattern of dysfunction in the middle-aged patient group...

Mental files theory explains why children pass many perspective taking tasks like the false belief test around age 4 (Perner & Leahy, 2016). It also explains why older children struggle to understand that beliefs about an object depend on how one is acquainted with it (intensionality or aspectuality). If Heinz looks at an object that is both a die and an eraser, but cannot tell by looking that it is an eraser, he will not reach for it if he needs an eraser. Four- to 6-year olds find this difficult (Apperly & Robinson, 1998)...

In 2 cross-lagged, longitudinal studies we contrasted parental talk about want in a single context versus multiple contexts. Study 1 examined thirty-two 2 year olds, with mothers describing pictures to children. Mothers could use want in zero, one, or multiple contexts. Children whose mothers used want in multiple contexts experienced a significantly larger gain in mental state terms over a 6-month period. Study 2 examined 50 preschoolers, measuring theory of mind (ToM) with tasks and mental state terms, then had parents intervene by reading booklets in which want was used in 1 or multiple contexts...

The goal of the current study was to statistically evaluate the reliable scalability of a set of tasks designed to assess Theory of Mind (ToM) without language as a confounding variable. This tool might be useful to study ToM in populations where language is impaired or to study links between language and ToM. Low verbal versions of the ToM tasks proposed by Wellman and Liu (2004) for their scale were tested in 234 children (2.5 years to 11.9 years). Results showed that 5 of the tasks formed a scale according to both Guttman and Rasch models whereas all 6 tasks could form a scale according to the Rasch model only...

Persuasion is an essential social skill. Yet its development and underpinnings are poorly understood. In 2 studies, a total of 167 children aged 3 to 12 years took theory of mind (ToM) tests and participated in unscripted, seminaturalistic persuasive conversations. Children were typically developing (TD) or had deafness or autism spectrum disorder (ASD). High-level, informationally rich persuasive arguments increased with age in all groups in both studies, as did ToM. In both studies, ToM scores predicted persuasion skill over and above age, language ability, and deafness/ASD status...

Bearing in mind the advantages of useful, cost-effective and eco-friendly synthesis, carbonized sugar (CS) has been synthesized via microwave-assisted carbonization of market quality table-top sugar. The as-prepared CS has been characterized for its morphology, phase purity, type of porosity and pore-size distribution. The gas sensing properties of CS for various oxidizing and reducing gases are demonstrated at ambient temperature where we observe good selectivity towards liquid ammonia amongst other gases...

Background: Individuals with autism spectrum disorder (ASD) frequently demonstrate symptoms of attention-deficit/hyperactivity disorder (ADHD). Previous findings in children with ASD have suggested that these symptoms are associated with an impairment in executive function (EF) abilities. However, studies rarely considered this association within a single framework that controls for other related factors such as Theory of Mind (ToM) abilities and ASD symptoms. Methods: We used structural equation modeling to explore the relations among EF, ToM, and symptoms of ASD and ADHD, using data from a population-based sample of 100 adolescents with ASD and full-scale IQ ≥ 50 (the Special Needs and Autism Project (SNAP) cohort)...

During the last decades, the focus in autism research has been progressively extended. Today it offers a large amount of material on sensorimotor disturbances as well as perceptive-cognitive preferences of people with autism. However, there are more and more critical voices against an intellectualist perspective in the cognitive sciences. The "enactive approach" as well as a new "movement perspective" to autism challenge the view of autism as a mere "cognitive" disturbance. They criticize the conception of a cognizing subject which is only interested in the world in as much as she/he can extract knowledge and organize it rationally...

BACKGROUND: Medical students can experience the transition from theory to clinical clerkships as stressful. Scientific literature on the mental health of clinical clerkship students is scarce and mental health is usually defined as absence of psychological distress without assessing psychological, emotional and social wellbeing, together called 'positive mental health'. This cross-sectional study examines the prevalence of psychological distress and positive mental health and explores possible predictors in a Dutch sample of clinical clerkship students...

Conceptually and methodologically, medical anthropology is well-positioned to support a "big-tent" research agenda on health and society. It fosters approaches to social and structural models of health and wellbeing in ways that are critically reflective, cross-cultural, people-centered, and transdisciplinary. In this review article, we showcase these four main characteristics of the field, as featured in Social Science & Medicine over the last fifty years, highlighting their relevance for an international and interdisciplinary readership...

In our "post-pluralistic era" (Cooper 2015), analysts, perhaps particularly in North America, are exposed to a multiplicity of formal theories in their training and their reading; their clinical work often reflects ideas drawn from more than one of them. An aspect of this development is the analyst's mental process as she draws on heterogeneous models when with the patient and when processing the events of the session afterward. A number of questions arise here: How does a new piece of clinical understanding, representing an alternative theoretical perspective-one that is not usually at the center of that analyst's thinking-enter the mind of the working analyst? How can the analyst assess whether this is a useful piece of understanding? How can the new piece become assimilated in the analyst's broader thinking? That is, how can the analyst's practice influence her theory? (Canestri 2006)...

Does theory of mind play a significant role in where people choose to hide an item or where they search for an item that has been hidden? Adapting Anderson's "Hide-Find Paradigm" Anderson et al. (Action, Perception and Performance, 76, 907-913, 2014) participants viewed homogenous or popout visual arrays on a touchscreen table. Their task was to indicate where in the array they would hide an item, or to search for an item that had been hidden, by either a friend or a foe. Critically, participants believed that their sitting location at the touchtable was the same as-or opposite to-their partner's location...

In this work, we present a collection of data from three replication studies of anticipatory looking false belief tasks measuring implicit Theory of Mind. Two paradigms, by Southgate & Senju and Surian & Geraci were replicated in two independent labs. Eye-tracking data was collected and processed in line with the original procedures to allow for an investigation of effects of false belief processing on looking times and first saccades.

BACKGROUND: Although Theory of Mind (ToM) impairment has been observed in patients with a wide range of mental disorders, the similarity and uniqueness of these deficits across diagnostic groups has not been thoroughly investigated. METHODS: We recruited 35 participants with schizophrenia (SCZ), 35 with bipolar disorder (BD), 35 with major depressive disorder (MDD), and 35 healthy controls in this study. All participants were matched in age, gender proportion and IQ estimates...

Advances in structural and functional neuroimaging offer new ways to conceptualize chronic pain disorders and to prevent, diagnose, and treat chronic pain. Advances in pain science, though, do not entail changes in the concepts of chronic pain in law and culture. Authoritative legal and cultural conceptions of chronic pain continue to promote abstruse theories, characterizing these disorders as arising out of everything from a person's unmet need for love to resistance to "patriarchy." These constructs have consequences, impeding treatment and affecting whether individuals with chronic pain can obtain legal redress...

Although one might expect parents' mind-mindedness (MM; the propensity to view children as mental agents) to relate to everyday mental-state talk (MST) and theory-of-mind capacity, evidence to support this view is lacking. In addition, both the uniqueness and the specificity of relations between parental MM, parental MST, and children's false belief understanding (FBU) are open to question. To address these three gaps, this study tracked 117 preschoolers (60 boys) and their parents across a 13-month period (Mage  = 3...

Allana L Canty, David L Neumann, David H K Shum
Individuals with schizophrenia often demonstrate theory of mind (ToM) impairment relative to healthy adults. However, the exact nature of this impairment (first- vs. second-order ToM and cognitive vs. affective ToM) and the extent to which ToM abilities deteriorate with illness chronicity is unclear. Furthermore, little is known about the relationships between clinical symptoms and ToM error types (overmentalising, reduced mentalising and no ToM) in early and chronic schizophrenia. This study examined the nature and types of ToM impairment in individuals with early (n = 26) and chronic schizophrenia (n = 32) using a novel virtual reality task...

Morten Tønnessen
In this paper, it is argued that Jakob von Uexküll's "search image" notion, the original version of this notion within ethology, is still of use. A search image, in Uexküll's sense, is an imagined object that an organism has in mind when it searches for something. Uexküll's conception of the search image is useful both for understanding the theoretical context of contemporary notions of search images, and with an eye to envisioning possible future developments of the idea. Uexküll's classical notion differs from contemporary versions in that it has a wider application, and is therefore of greater relevance to theoretical biology and cognitive science...

Theory of Mind (ToM), i.e. the ability to understand others' mental states, endows humans with highly adaptive social skills such as teaching or deceiving. Candidate evolutionary explanations have been proposed for the unique sophistication of human ToM among primates. For example, the Machiavellian intelligence hypothesis states that the increasing complexity of social networks may have induced a demand for sophisticated ToM. This type of scenario ignores neurocognitive constraints that may eventually be crucial limiting factors for ToM evolution...

Many contemporary accounts of human reasoning assume that the mind is equipped with multiple heuristics that could be deployed to perform a given task. This raises the question of how the mind determines when to use which heuristic. To answer this question, we developed a rational model of strategy selection, based on the theory of rational metareasoning developed in the artificial intelligence literature. According to our model people learn to efficiently choose the strategy with the best cost-benefit tradeoff by learning a predictive model of each strategy's performance...
