Overestimation of volatility in schizophrenia and autism? A comparative study using a probabilistic reasoning task.

ABSTRACT:

Background and objectives

A plethora of studies has investigated and compared social cognition in autism and schizophrenia ever since both conditions were first described in conjunction more than a century ago. Recent computational theories have proposed similar mechanistic explanations for various symptoms beyond social cognition. They are grounded in the idea of a general misestimation of uncertainty but so far, almost no studies have directly compared both conditions regarding uncertainty processing. The current study aimed to do so with a particular focus on estimation of volatility, i.e. the probability for the environment to change.

Methods

A probabilistic decision-making task and a visual working (meta-)memory task were administered to a sample of 86 participants (19
