Abstract
Emotional information can influence various cognitive processes, such as attention, motivation, and memory. Differences in the processing of emotion have been observed in individuals with high levels of autism-like traits. The current study aimed to determine the influence of emotional prosody on word learning ability in neurotypical adults who varied in their levels of autism-like traits. Thirty-eight participants learned 30 nonsense words as names for 30 “alien” characters. Alien names were verbally presented with happy, fearful, or neutral prosody. For all participants, recall performance was significantly worse for words spoken with fearful prosody compared to neutral. Recall performance was also worse for words spoken with happy prosody compared to neutral, but only for those with lower levels of autism-like traits. The findings suggest that emotional prosody can interfere with word learning, and that people with fewer autism-like traits may be more susceptible to such interference due to a higher attention bias toward emotion.
