Abstract

Inconsistent data are available on mental rotation performance in neurotypicals with high autistic-like traits. Here, we tested whether global-local visual processing abilities mediate the influence of specific autistic-like trait domains (social skill, attention switching, attention-to-detail, communication, and imagination) on mental rotation. Neurotypical participants (N = 128) underwent an assessment of autistic-like traits, a flanker task with hierarchical stimuli, and a mental rotation task. Path analysis showed that Reaction Times on the incongruent/local condition of the flanker task mediated the relationship between attention-to-detail and mental rotation accuracy. These findings indicate that a better capacity of ignoring incongruent global information to identify local information (reduced global interference) in persons with high non-social autistic-like traits, as attention-to-detail, facilitates mental rotation performance.
