Time in action contexts: learning when an action effect occurs.

Area of Science:

• Cognitive Psychology
• Neuroscience
• Human-Computer Interaction

Background:

• The ideomotor principle (IMP) explains action-effect learning, but temporal aspects are less understood.
• Action effects typically follow actions with specific, non-random delays.

Purpose of the Study:

• To investigate the acquisition and behavioral relevance of temporal delays between actions and their effects.
• To determine if humans learn and utilize specific action-effect timing for behavioral control.

Main Methods:

• Participants performed actions and observed contingent effects with varying temporal delays.
• Behavioral responses to effects presented at usual, earlier, and later than usual delays were recorded.

Main Results:

• Participants demonstrated slower responses to effects that occurred earlier than the learned delay.
• Participants exhibited premature responses when effects occurred later than the learned delay.

Conclusions:

• Humans actively learn and exploit temporal regularities between actions and effects.
• This learning of action-effect timing influences subsequent behavioral control, contrary to simple temporal perception biases.
