Abstract Objectives First, to see whether previous studies showing a limited capacity to spontaneously evoke the past and the future of a present moment (diachronic tendency) and a prevalence of mental images over inner speech (thinking style) in individuals with autism spectrum disorder could be replicated in individuals belonging to the broader autism phenotype. Second, to test the hypothesis that individuals thinking with mental images have a more limited diachronic tendency compared with individuals thinking with inner speech. Methods Adults (N = 309, Mage = 31.5 years, 76% women) with at least a high school degree were assessed with the Autism Spectrum Quotient, a test of diachronic tendency comprising four pictures varying in social interactivity and dynamicity, and a thinking style scale comprising three items representing three different everyday situations. Results The results showed that adults with many autistic traits have a limited diachronic tendency but only when the situation is socially interactive and dynamic, think more in mental images than individuals with no or few autistic traits but nevertheless still think more with inner speech than with mental images, and the more the participants reported thinking in inner speech, the more they evoked past and future events when describing a socially interactive and dynamic situation. Conclusions More autistic traits are associated with a limited diachronic tendency in socially interactive and dynamic situations and more thinking in mental images, and thinking style could be one of the determinants of diachronic tendency in socially interactive and dynamic situations.

The Relationship

Little is known about the relationship between the personality and the emotional experiences of people with broader autism phenotype (BAP) or autistic traits. Given that music is a powerful vehicle for conveying emotions and that several studies show that people with and without autism spectrum disorder (ASD) typically respond to music in similar ways, the present study examines the relationship between personality, autistic traits, and emotional experiences evoked by music. A total of 110 participants ( n = 74 females) aged 18 to 35 years ( M = 21.25, SD = 3.36) completed the NEO-Five Factor Inventory-3-S, Social Responsiveness Scale-2, Autism-Spectrum Quotient, and Goldsmiths Musical Sophistication Index self-report questionnaires. Path analyses revealed that the relationship between autistic traits and emotional responsiveness to music was fully mediated by extraversion, and to a lesser extent openness to experience. These results suggest that people in the general population who have fewer autistic traits and who tend to be extraverted and open to experience report greater emotional responsiveness to music than those who are less extraverted and less open to experience. These findings suggest that it is important to consider personality characteristics when considering the relationship between autistic traits and emotional experiences.

Abstract Background Traits and characteristics qualitatively similar to those seen in diagnosed autism spectrum disorder can be found to varying degrees in the general population. To measure these traits and facilitate their use in autism research, several questionnaires have been developed that provide broad measures of autistic traits [e.g. Autism-Spectrum Quotient (AQ), Broad Autism Phenotype Questionnaire (BAPQ)]. However, since their development, our understanding of autism has grown considerably, and it is arguable that existing measures do not provide an ideal representation of the trait dimensions currently associated with autism. Our aim was to create a new measure of autistic traits that reflects our current understanding of autism, the Comprehensive Autism Trait Inventory (CATI). Methods In Study 1, 107 pilot items were administered to 1119 individuals in the general population and exploratory factor analysis of responses used to create the 42-item CATI comprising six subscales: Social Interactions, Communication, Social Camouflage, Repetitive Behaviours, Cognitive Rigidity, and Sensory Sensitivity. In Study 2, the CATI was administered to 1068 new individuals and confirmatory factor analysis used to verify the factor structure. The AQ and BAPQ were administered to validate the CATI, and additional autistic participants were recruited to compare the predictive ability of the measures. In Study 3, to validate the CATI subscales, the CATI was administered to 195 new individuals along with existing valid measures qualitatively similar to each CATI subscale. Results The CATI showed convergent validity at both the total-scale (r ≥ .79) and subscale level (r ≥ .68). The CATI also showed superior internal reliability for total-scale scores (α = .95) relative to the AQ (α = .90) and BAPQ (α = .94), consistently high reliability for subscales (α > .81), greater predictive ability for classifying autism (Youden’s Index = .62 vs .56–.59), and demonstrated measurement invariance for sex. Limitations Analyses of predictive ability for classifying autism depended upon self-reported diagnosis or identification of autism. The autistic sample was not large enough to test measurement invariance of autism diagnosis. Conclusions The CATI is a reliable and economical new measure that provides observations across a wide range of trait dimensions associated with autism, potentially precluding the need to administer multiple measures, and to our knowledge, the CATI is also the first broad measure of autistic traits to have dedicated subscales for social camouflage and sensory sensitivity.

AbstractThe affinity for hikikomori represents the desire to be withdrawn, as well as to entertain an empathetic attitude towards withdrawn individuals. It is composed of two subdimensions, the maladaptive desire for hikikomori, and empathy for others with hikikomori. This longitudinal study examined whether autistic traits predicted the affinity for hikikomori. At the baseline assessment, undergraduate and graduate students in Japan (N = 272) completed the Autism-Spectrum Quotient (AQ), the Affinity for Hikikomori Scale in University Students, and measures assessing academic failures and interpersonal conflicts. They also completed all measures excluding the AQ eight weeks later. Structural equation modeling indicated that difficulties in social interaction aspects of autistic traits were positively associated with academic failures at Time 2 even after controlling for academic failures at Time 1. In addition, difficulties in social interaction were positively related to the desire for hikikomori at Time 2 indirectly via academic failures at Time 2 after controlling for the desire for hikikomori at Time 1. Difficulties in social interaction were also directly associated with the increased desire for hikikomori at Time 2. These findings suggest that autistic traits, and especially difficulties in social interaction, are predictors of the maladaptive aspect of the affinity for hikikomori.

Feeding And Eating Disorders

Abstract Background Autism spectrum disorder (ASD) and feeding and eating disorders (FEDs) such as anorexia nervosa (AN) are strongly linked as evidenced by frequent comorbidity and overlapping traits. However, eating and social behaviors are shaped by culture, so it is critical to examine these associations in different populations. Moreover, FEDs are heterogeneous, and there has been no examination of autistic traits in avoidant/restrictive food intake disorder (ARFID). Methods Therefore, we investigated the prevalence of ASD and autistic traits among Japanese children with AN (n = 92) or ARFID (n = 32) from a prospective multicenter cohort study using the Autism Spectrum Quotient Children’s version (AQC) and Children’s Eating Attitudes Test (ChEAT26). Results ASD prevalence was high in both AN and ARFID (16.3 and 12.5%, respectively). The AN group exhibited significantly higher scores on all AQC subscales than an age-matched healthy control (HC) group, but there were no significant correlations between AQC scores and ChEAT26 scores. In the AFRID group, AQC scores did not differ from HCs, but significant correlations were found between total AQC and ChEAT26 scores and between several AQC and ChEAT26 subscales. Conclusions Both the AN and ARFID groups had high prevalence rates of ASD. The AN group showed a significantly higher degree of autistic traits than the HC group; however, no difference was found between the ARFID and HC groups. Clinicians need to be aware of these rates when working with children with ED.

Underlying Processes

Both individuals with diagnosed with Autism Spectrum Disorder (ASD) and individuals high in psychopathic traits show reduced susceptibility to contagious yawning; that is, yawning after seeing or hearing another person yawn. Yet it is unclear whether the same underlying processes (e.g., reduced eye gaze) are responsible for the relationship between reduced contagion and these very different types of clinical traits. College Students (n = 97) watched videos of individuals yawning or scratching (a form of contagion not reliant on eye gaze for transmission) while their eye movements were tracked. They completed the Interpersonal Reactivity Index (IRI), the Autism-Spectrum Quotient (AQ), the Psychopathy Personality Inventory-Revised (PPI-R), and the Adolescent and Adult Sensory Processing Disorder Checklist. Both psychopathic traits and autistic traits showed an inverse relationship to contagious yawning, consistent with previous research. However, the relationship between autistic (but not psychopathic) traits and contagious yawning was moderated by eye gaze. Furthermore, participants high in autistic traits showed typical levels of contagious itching whereas adults high in psychopathic traits showed diminished itch contagion. Finally, only psychopathic traits were associated with lower overall levels of empathy. The findings imply that the underlying processes contributing to the disruptions in contagious yawning amongst individuals high in autistic vs. psychopathic traits are distinct. In contrast to adults high in psychopathic traits, diminished contagion may appear amongst people with high levels of autistic traits secondary to diminished attention to the faces of others, and in the absence of a background deficit in emotional empathy.

Abstract Background: Previous studies have demonstrated that individuals with autism spectrum disorder (ASD) exhibit dysfunction in the three attention systems (i.e., alerting, orienting, and executive control) as well as atypical relationships among these systems. Additionally, other studies have reported that individuals with subclinical but high levels of autistic traits show similar attentional tendencies to those observed in ASD. Based on these findings, it was hypothesized that autistic traits would affect the functions and relationships of the three attention systems in a general population. Resting-state functional magnetic resonance imaging (fMRI) was performed in 119 healthy adults to investigate relationships between autistic traits and within- and between-system functional connectivity (FC) among the three attention systems. Twenty-six regions of interest that were defined as components of the three attention systems by a previous task-based fMRI study were examined in terms of within- and between-system FC. We assessed autistic traits using the Autism-Spectrum Quotient.Results: Correlational analyses revealed that autistic traits were significantly correlated with between-system FC, but not with within-system FC. Conclusions: Our results imply that a high autistic trait level, even when subclinical, is associated with the way the three attention systems interact.

Objective: To find the relationship involving autistic traits, paranormal beliefs and emotional response bias in obsessive compulsive disorder patients. Method: The cross-sectional quasi-experimental study was conducted from November 2017 to November 2018 at the Government College University, Lahore, Pakistan, and comprised patients with obsessive compulsive disorder and healthy controls from the general population aged 20-40 years. Data was collected using the self-reporting Autism Spectrum Quotient, the Revised Paranormal Belief Scale, the Emotional Recognition Task and the Obsessive Compulsive Disorder symptom checklist. Data was analysed using SPSS 20. Results: Of the 140 participants, there were 70(50%) patients and as many controls. Overall, there were 72(52%) males and 68(48%) females. High level of autistic traits (p<0.001) and paranormal beliefs (p<0.001) had a significant impact on obsessive compulsive disorder. Impairments in recognition of emotions were related to the presence of high autistic traits and obsessive compulsive symptoms in the patients group (p<0.05). Emotion of disgust (p<0.001) was significantly impaired in the patients, while the differences were not significant in terms of emotions of happiness and surprise (p>0.05). Conclusion: Autistic traits, paranormal beliefs and emotional response bias were found to have a significant relationship in obsessive compulsive disorder patients.   Continuous....

Purpose The Autism-Spectrum Quotient (AQ) is a widely used tool to quantify autistic traits in the general population. This study aims to report the distribution, group differences and factor structure of autistic traits in Indian general population. The work also assesses the criterion validity of AQ across three patient group samples – autism spectrum disorder (ASD), obsessive-compulsive disorder and social anxiety disorder. Design/methodology/approach In this study, psychometric properties of the adapted AQ were assessed among 450 neurotypical university students matched for age. Confirmatory factor analysis was done to see if the adapted AQ fits the original factor structure. Test–retest, internal consistency reliability and criterion validity were found out. Group differences (gender and field of study) in AQ were also assessed. Findings Autistic traits were found to be continuously distributed in the population, and patterns of group differences were consistent with previous studies. The adapted AQ had five factors resembling the original factor structure with a good fit, and 38 items instead of the original 50 items. Acceptable reliability coefficients were demonstrated along with criterion validity across clinical groups. Originality/value This work is the first to present the pattern of distribution and factor structure of autistic traits among neurotypical adults from Eastern India, a culturally different population, as well as a reliable and valid tool to assess autistic traits in Bengali, a language with 300 million speakers. The findings add to the growing literature on AQ measurement and the concept of autism as a quantitative trait, examined outside of the western samples.

Abstract Background Both psychotic and autistic traits are related to poor social outcome in individuals with psychotic disorders (PD). However, it is unknown how specific trait clusters relate to each other and which are pivotal to social functioning. The aim of the present study was to use a network approach to address this issue and to investigate whether relations are similar in individuals with a familial risk for psychosis (FR) or typical comparisons (TC). Methods The total sample consisted of 1413 individuals (504 PD, 572 FR, and 337 TC). Traits were assessed with the Autism Spectrum Quotient (AQ; 5 nodes) and the Community Assessment of Psychic Experiences (CAPE; 9 nodes). Social functioning was measured with the Social Functioning Scale (7 nodes). Results Overall our results show that autistic traits are more negatively and closely related to social functioning, particularly in the interpersonal environment, than psychotic traits. These relations are more intrinsically connected for the PD network, as more and stronger connections between nodes were observed than for the FR and TC networks. In addition, the latter two networks appeared strikingly similar with only few unique relations. Discussion Presence of autistic traits generally have a negative effect on social functioning, but in PD they may have a disproportional detrimental effect on psychopathology and levels of social functioning. These findings emphasize the need for increased clinical awareness of autistic comorbidity in psychotic patients to help enrich their daily social environments.

ABSTRACTWe conducted a web-based study investigating whether the probability of deriving four types of pragmatic inferences depends on the degree to which one has traits associated with the autism spectrum, as measured by the autism spectrum quotient test (Baron-Cohen, Wheelwright, Skinner, Martin, & Clubley, 2001). In line with previous research, we show that, independently of their autism spectrum quotient, participants are likely to derive those pragmatic inferences that can be derived by reasoning solely about alternatives that the speaker could have used. However, if the derivation of the pragmatic inference draws upon more complex counterfactual reasoning about what the speaker could have said, the probability that it is derived decreases significantly with one’s autism quotient. We discuss the consequences for theories of pragmatics in autism and for linguistic theorizing in general.
