Multiple priming instances increase the impact of practice-based but not verbal code-based stimulus-response...

Area of Science:

• Cognitive Psychology
• Neuroscience
• Behavioral Science

Background:

• Stimulus-response (S-R) associations are fundamental to learning and automaticity.
• Repeated exposure (priming) typically strengthens S-R associations.
• The impact of multiple priming instances on verbally instructed S-R associations is not well understood.

Purpose of the Study:

• To investigate if multiple priming instances strengthen S-R associations formed via verbal coding instructions.
• To compare the effect of multiple priming instances on S-R associations formed through active task execution versus verbal coding.

Main Methods:

• Participants performed active stimulus classification or passively attended to verbal response codes.
• Stimulus-response association strength was probed after single or multiple (four) priming instances.
• Experimental design compared effects of practice versus instruction-based priming.

Main Results:

• S-R associations strengthened with multiple priming instances when formed through active task execution (practice).
• S-R associations did not show increased strength with multiple priming instances when formed via verbal coding instructions.
• Findings indicate distinct mechanisms for encoding/retrieval of practiced versus instructed S-R associations.

Conclusions:

• Active task execution and verbal coding rely on different mechanisms for S-R association formation and strengthening.
• The benefits of repeated priming are specific to the method of association formation.
• Understanding these differences is crucial for optimizing learning and behavioral interventions.
