Adolescent-Specific Motivation Deficits in Autism Versus Typical Development

Area of Science:

• Neurodevelopmental disorders
• Developmental psychology
• Autism spectrum disorder research

Background:

• Autism spectrum disorder (ASD) is a neurodevelopmental condition characterized by social communication challenges.
• Understanding motivational differences in autism across developmental stages is crucial for supporting individuals.
• Adolescence and early adulthood represent critical transition periods for individuals with autism.

Purpose of the Study:

• To investigate age-related differences in motivation and attention to social and non-social cues in autism.
• To compare motivational responses in typically developing individuals and those with autism from adolescence to early adulthood.

Main Methods:

• A cross-sectional study involving 156 typically developing individuals and 79 individuals with autism, aged 10-30 years.
• Participants completed a go/nogo task assessing responses to social and non-social cues.
• Linear and quadratic models were employed to analyze age effects on performance.

Main Results:

• Typically developing individuals showed increased false alarms for positive social cues compared to neutral cues, consistent with prior research.
• Individuals with autism did not exhibit significant age-related changes in attention to social or non-social cues.
• A notable finding was reduced orienting to motivating cues in autism during late adolescence and early adulthood.

Conclusions:

• Findings suggest a developmental divergence in motivational processing between typically developing individuals and those with autism.
• Reduced sensitivity to motivating cues in autism during adolescence and early adulthood may contribute to challenges during life transitions.
• This research offers insights into the unique developmental trajectory of motivation in autism spectrum disorder.
