Responses guide attention

Area of Science:

• Cognitive Psychology
• Neuroscience
• Human Attention Studies

Background:

• Learning stimulus-response regularities is vital for effective functioning.
• The impact of these learned regularities on attentional selection is not fully understood.

Purpose of the Study:

• To investigate if motor responses predicting search target locations can direct attention.
• To explore the phenomenon of response-induced attention.

Main Methods:

• Participants engaged in a dual task: an identification task followed by a search task.
• In the acquisition phase, responses to central stimuli predicted search target locations.
• Test phases altered stimuli while maintaining response-location contingencies to isolate the effect of responses.

Main Results:

• Faster search target detection occurred at response-cued locations, indicating an attentional bias.
• This effect persisted even when the original stimuli predicting locations were changed, confirming response-driven attention.
• The study confirmed that responses, rather than visual cues, guided attention.

Conclusions:

• Motor responses play a significant role in the intelligent allocation of attention.
• Learned response-stimulus regularities can shape attentional selection, highlighting the importance of the motor system in perception.
