Effects of emotional cues on novel word learning in typically developing children in relation to broader autism traits.

Emotion can influence various cognitive processes. Communication with children often involves exaggerated emotional expressions and emotive language. Children with autism spectrum disorder often show a reduced tendency to attend to emotional information. Typically developing children aged 7 to 9 years who varied in their level of autism-like traits learned the nonsense word names of nine novel toys, which were presented with either happy, fearful, or neutral emotional cues. Emotional cues had no influence on word recognition or recall performance. Eye-tracking data showed differences in visual attention depending on the type of emotional cues and level of autism-like traits. The findings suggest that the influence of emotion on attention during word learning differs according to whether the children have lower or higher levels of autism-like traits, but this influence does not affect word learning outcomes.

Cross-modal emotion recognition and autism-like traits in typically developing children.

The ability to explicitly recognize emotions develops gradually throughout childhood, and children usually have greater difficulty in recognizing emotions from the voice than from the face. However, little is known about how children integrate vocal and facial cues to recognize an emotion, particularly during mid to late childhood. Furthermore, children with an autism spectrum disorder often show a reduced ability to recognize emotions, especially when integrating emotion from multiple modalities. The current preliminary study explored the ability of typically developing children aged 7-9 years to match emotional tones of voice to facial expressions and whether this ability varies according to the level of autism-like traits. Overall, children were the least accurate when matching happy and fearful voices to faces, commonly pairing happy voices with angry faces and fearful voices with sad faces. However, the level of autism-like traits was not associated with matching accuracy. These results suggest that 7- to 9-year-old children have difficulty in integrating vocal and facial emotional expressions but that differences in cross-modal emotion matching in relation to the broader autism phenotype are not evident in this task for this age group with the current sample.

Immersive and maladaptive daydreaming and divergent thinking in autism spectrum disorders.

Little is known about the internal mental experiences of individuals with ASD. While some research suggests a limited capacity for imagination, other studies show heightened interest in fantasy and unique forms of creative thinking in ASD. This study explored daydreaming experiences in adults with ASD, with a focus on immersive daydreaming and its relation to divergent thinking abilities. Individuals with and without a diagnosis of ASD were surveyed on their daydreaming habits and completed a divergent thinking task. Experiences of immersive daydreaming were identified in 42% of adults with ASD and were related to broad ASD traits in those without a diagnosis of ASD. However, ASD diagnosis was unrelated to originality of divergent thinking, which was negatively associated with immersive daydreaming. Moreover, daydreaming experiences in ASD were diverse. A more nuanced understanding of the mental experiences in ASD may assist in the development of interventions and support for this population.

Effects of Prosodic and Semantic Cues on Facial Emotion Recognition in Relation to Autism-Like Traits.

The current study investigated whether those with higher levels of autism-like traits process emotional information from speech differently to those with lower levels of autism-like traits. Neurotypical adults completed the autism-spectrum quotient and an emotional priming task. Vocal primes with varied emotional prosody, semantics, or a combination, preceded emotional target faces. Prime-target pairs were congruent or incongruent in their emotional content. Overall, congruency effects were found for combined prosody-semantic primes, however no congruency effects were found for semantic or prosodic primes alone. Further, those with higher levels of autism-like traits were not influenced by the prime stimuli. These results suggest that failure to integrate emotional information across modalities may be characteristic of the broader autism phenotype.
