“…For instance, it could indicate a high memory performance, a high attention to colours, or a high degree of conscientiousness. The latter possibility, however, would not account for the relation between the degree of synaesthesia and autistic traits that we found, as a recent meta-analysis (Lodi-Smith et al 2018) found conscientiousness to be negatively correlation with ASD characteristics. This limitation concerns the widely discussed debate whether synaesthesia should be considered as a continuous traits or all-or-none phenomenon, as discussed in the introduction.…”

Synaesthesia is highly prevalent in autism spectrum disorder. We assessed the relation between the degree of autistic traits (Autism Spectrum Quotient, AQ) and the degree of synaesthesia in a neurotypical population, and hypothesized both are related to a local bias in visual perception. A positive correlation between total AQ scores and the degree of synaesthesia was found, extending previous studies in clinical populations. Consistent with our hypothesis, AQ-attention to detail scores were related to increased performance on an Embedded Figures Task and reduced susceptibility to visual illusions. We found no relation between autistic traits and performance on a motion coherence task, and no relation between synaesthesia and local visual perception. Possibly, this relation is reserved for supra-threshold synaesthetes.

“…The correlations of the Big Five personality traits with the total RAADS-14 Rus score, taken as a general measure of autistic traits, were highly consistent with the earlier findings [41], revealing moderate positive correlations with Neuroticism, moderate negative correlation with Extraversion, and weaker negative correlations with Agreeableness, Openness to experience, and Conscientiousness, similarly to a study using RAADS-R and IPIP-NEO-120 [42]. These results support good discriminative validity of the RAADS-14 Rus and confirm our prediction that the character of the relation between autistic traits, as measured by the RAADS-14 Rus, and the Big Five personality traits for the Russian sample is similar to such relation for other national populations.…”

“…There are numerous studies exploring the links between the autism traits and other personality factors and constructs. The Big Five personality model is probably the most well-established general personality construct [24] which was found to strongly relate to the autism traits in a large number of studies, consistently revealing moderate positive correlations of ASD scores to neuroticism, and weak to moderate negative correlations to all the other Big Five factors [25]. A study utilizing multivariate approaches to explore the relations between IPIP-NEO-120 and RAADS-R scores found that Big Five personality factors accounted for 70 % of variance in autism trait scores [26].…”

The general aim of our research was to construct and validate a Russian version of the RAADS-14 (the RAADS-14 Rus), a short self-report questionnaire designed for ASD screening, to provide the initial reference point in developing the body of instruments for assessing autistic traits in Russian-speaking adult population. This measure was chosen due to its good psychometric characteristics, reported ability to provide initial assessment for differential diagnosis, and simplicity of use. The data were collected for the total of 1569 adults, including groups of non-psychiatrical controls (n=849), adults with self-diagnosed ASD (n=91), and adults with clinically established ASD (n=25). The RAADS-14 Rus is characterized by good reliability and satisfactory construct and discriminative validity. The factor structure of the RAADS-14 Rus is similar to the factor structure of the original version and includes three domains: Social mentalizing, Social anxiety, and Sensory and cognitive perception, the between-factor correlations varying from .25 to .51. According to the initial assessment, the discriminative properties are also good (AUC = .88). The mean values of the RAADS-14 total scores for the non-psychiatrical population were notably higher than the original RAADS-14 total scores (median = 13 compared to 3) confirming prior anecdotal evidences of greater mean scores yielded by international ASD assessment tools on Russian-speaking populations. The correlations of the RAADS-14 Rus total score with the Big Five personality trait scores were similar to the data previously obtained for other national samples.The results of the study indicate that RAADS-14 Rus is a promising tool for ASD screening and can become one of the first stepping-stones in establishing a comprehensive system of ASD assessment and diagnostics for adult Russian-speaking population.

“…ASD and SZ share elevated levels of schizotypal personality traits and neuroticism, which go along with difficulties in social life. In healthy subjects, these traits increase the risk for the disorders independent of other risks [10][11][12][13] and they are dimensionally distributed among healthy subjects and patients [14]. It is yet unknown, whether APA leads to neuroticism or schizotypy in the offspring, and if so, what the underlying mechanisms are.…”

Advanced paternal age as a risk factor for neurodevelopmental disorders: a translational study

et al. 2020

View full text Add to dashboard Cite

Advanced paternal age (APA) is a risk factor for several neurodevelopmental disorders, including autism and schizophrenia. The potential mechanisms conferring this risk are poorly understood. Here, we show that the personality traits schizotypy and neuroticism correlated with paternal age in healthy subjects (N = 677). Paternal age was further positively associated with gray matter volume (VBM, N = 342) in the right prefrontal and the right medial temporal cortex. The integrity of fiber tracts (DTI, N = 222) connecting these two areas correlated positively with paternal age. Genome-wide methylation analysis in humans showed differential methylation in APA individuals, linking APA to epigenetic mechanisms. A corresponding phenotype was obtained in our rat model. APA rats displayed social-communication deficits and emitted fewer pro-social ultrasonic vocalizations compared to controls. They further showed repetitive and stereotyped patterns of behavior, together with higher anxiety during early development. At the neurobiological level, microRNAs miR-132 and miR-134 were both differentially regulated in rats and humans depending on APA. This study demonstrates associations between APA and social behaviors across species. They might be driven by changes in the expression of microRNAs and/or epigenetic changes regulating neuronal plasticity, leading to brain morphological changes and fronto-hippocampal connectivity, a network which has been implicated in social interaction.
