Cue-weighting in perception and production demonstrates variation at the individual level, some of which can be attributed to different cognitive styles, such as autistic character traits. We examined the effects of autistic character traits on cue-weighting of prosodic focus, which is realized along multiple phonetic dimensions including f0, intensity, and duration. We report the results of 18 participants divided into two groups based on their Autism Spectrum Quotient (AQ) scores: a high AQ group (AQ > 124) and a low AQ group (AQ < 104). In a perception task, participants had to identify the noun in focus manipulated in f0, intensity, and duration, presented with natural-focus-production-range values (full condition) or below these values (half condition). In a production task, participants produced nouns in out-of-focus, broad focus, and narrow focus conditions. For perception, we found that high AQ participants differed significantly from low AQ participants by their perception of pitch (p<.019*) and intensity (p<.01**), but not duration (p<.158). For production, no significant effect of AQ level across any of the acoustic parameters was found. We conclude that perception is more sensitive to individual cognitive differences than production, and that, for perception, individuals with higher levels of autistic traits are better able to detect fine-grained differences in speech stimuli.
