Studies have shown that during social interaction a shared system underlies inferring one’s own mental state, and the mental states of others – processes often referred to as mentalization. However, no validated assessment has been developed to measure second order mentalization, or whether this capacity plays a significant role in social interaction. The current work presents a interactive mentalization theory, which divides these directional and second order aspects of mentalization, and investigates whether these constructs are measurable, stable, and meaningful in (...) social interactions. We developed a 20-item, self-report interactive mentalization questionnaire in order to assess the different sub-components of mentalization: self–self, self–other, and other–self mentalization. We then tested this scale on a large, online sample, and report convergent and discriminant validity in the form of correlations with other measures, as well as correlations with social deception behaviors in real online interaction with Mturk studies. These results validate the IMQ, and support the idea that these three factors can predict mentalization in social interaction. (shrink)

Among all their sensations, agents need to distinguish between those caused by themselves and those caused by external causes. The ability to infer agency is particularly challenging under conditions of uncertainty. Within the predictive processing framework, this should happen through active control of prediction error that closes the action-perception loop. Here we use a novel, temporally-sensitive, behavioural proxy for prediction error to show that it is minimised most quickly when volatility is high and when participants report agency, regardless of the (...) accuracy of the judgement. We demonstrate broad effects of uncertainty on accuracy of agency judgements, movement, policy selection, and hypothesis switching. Measuring autism traits, we find differences in policy selection, sensitivity to uncertainty and hypothesis switching despite no difference in overall accuracy. (shrink)

This paper suggests that autistic people relate to themselves via a third-person perspective, an objective and explicit mode of access, while neurotypical people tend to access the different dimensions of their self through a first-person perspective. This approach sheds light on autistic traits involving interactions with others, usage of narratives, sensitivity and interoception, and emotional consciousness. Autistic people seem to access these dimensions through comparatively indirect and effortful processes, while neurotypical development enables a more intuitive sense of self.
