Repeated Task Exposure and Sufficient Sleep May Mitigate ADHD-Related Cognitive Flexibility Impairments in Family...

Area of Science:

• Comparative Psychology
• Neuroscience
• Animal Behavior

Background:

• The family dog serves as a relevant model for understanding human cognitive functions and psychological disorders like ADHD.
• Human research indicates cognitive flexibility impairments are associated with ADHD.

Purpose of the Study:

• To investigate the link between canine ADHD-like traits and reversal learning performance.
• To examine the impact of sleep on this association in dogs.

Main Methods:

• Sixty-four family dogs completed a spatial reversal learning task.
• Non-invasive sleep electroencephalography (EEG) was recorded for one hour post-task.
• A validated human analogue questionnaire assessed ADHD traits in dogs.

Main Results:

• Dogs with higher ADHD scores needed more trials for initial reversal learning, but this deficit diminished post-sleep.
• Higher ADHD scores correlated with slower electrode application and increased sleep measurement failures.
• Dogs with higher ADHD scores showed greater performance improvement after sleep, particularly if they slept for at least 40% of the recording.

Conclusions:

• Findings support the association between ADHD traits and cognitive flexibility in dogs, mirroring human studies.
• Sufficient sleep enhances cognitive flexibility in dogs with ADHD-like traits.
• Cognitive training post-sleep presents a potential strategy to ameliorate ADHD-related cognitive impairments in dogs.
