Information gathering: dissociable effects of autistic and alexithymic traits in youths aged 6–25 years

Journal article

Autistic youths tend to react negatively to uncertain events. Little is known about the cognitive processes associated with this intolerance of uncertainty, most notably the tendency to actively gather information to minimize uncertainty. Past research has relied on self-report measures that may not allow investigation of the multifaceted processes associated with intolerance of uncertainty, including information gathering. Alexithymia (difficulties in identifying and describing one’s own emotions) commonly co-occurs with autistic traits, but its role in information gathering has rarely been considered. Accordingly, 97 typically developing youths (aged 6–25 years) performed an information gathering task in which they were asked to gather information to infer socioemotional (emotional state) and nonsocial (clothing preference) information about another person when information gathering was costly versus not costly. Dimensional autistic traits were associated with more information gathering regardless of costs and information type. Computational modeling suggested this may be because of the delayed emergence of subjective costs of information gathering in high autistic trait individuals, resulting in later guesses. Alexithymia was uniquely associated with inconsistent emotional responses to rewards and losses and to reduced information gathering about emotional states when assessed using parent-report measures. Future validation in youths diagnosed with autism is warranted to test the generalizability of the findings.
