Factors responsible for performance on the day-night task: response set or semantics?

Area of Science:

• Cognitive Development
• Developmental Psychology
• Executive Functions

Background:

• Previous research suggested the day-night task requires inhibition due to semantic relations between stimuli and responses.
• An alternative explanation, the response set effect, was not fully explored in prior studies.

Purpose of the Study:

• To investigate the roles of semantic relatedness and response set in the inhibitory demands of the day-night task.
• To differentiate the contributions of semantic interference and response set effects on children's performance.

Main Methods:

• Two experiments were conducted with children aged 4 to 11 years.
• Participants completed four conditions designed to isolate semantic and response set effects.
• Performance was compared across conditions with varying stimulus-response mappings and response set congruency.

Main Results:

• Response set emerged as a significant factor influencing performance across all tested age groups.
• The effect of semantic relatedness was less pronounced compared to the response set effect.
• Children's ability to inhibit responses was strongly modulated by whether stimuli and responses shared the same set.

Conclusions:

• The findings indicate that response set plays a critical role in the inhibitory demands of the day-night task for children.
• This challenges the sole reliance on semantic relatedness as the primary driver of inhibition in this task.
• Results contribute to understanding executive functions and inhibitory control development in children.
