Using position rather than color at the traffic light - Covariation learning-based deviation from instructions in...

Area of Science:

• Cognitive Psychology
• Neurodevelopmental Disorders

Background:

• Instructions can create rigid task representations, hindering learning of more efficient methods.
• Attention deficit/hyperactivity disorder (ADHD) is associated with reduced task shielding, potentially facilitating adaptation.

Purpose of the Study:

• To investigate if individuals with ADHD are quicker to abandon suboptimal instructed task strategies compared to controls.
• To examine the role of stimulus feature learning and utilization in task adaptation.

Main Methods:

• An online study using a covariation learning paradigm where participants responded to stimulus color.
• Manipulation of stimulus features (color and position) to assess reliance on instructed vs. covarying cues.
• Comparison of reaction times and error rates between participants with and without ADHD.

Main Results:

• The online covariation learning task was successfully administered to adult participants.
• ADHD participants showed potential increases in attention to non-instructed features with practice.
• No significant difference was found in the utilization of the non-instructed feature between ADHD and control groups.

Conclusions:

• Participants with ADHD do not appear to lag in abandoning instructed task processing for learned strategies.
• The study supports the adaptability of individuals with ADHD in complex learning environments.
• Task shielding differences may not translate to slower adaptation in this specific learning context.
