Effect-less? Event-files are not terminated by distal action effects

Area of Science:

• Cognitive Psychology
• Neuroscience
• Action Control

Background:

• Event-files link stimuli, responses, and action effects in action control theories.
• Retrieval of past event-files influences current performance when features repeat.
• The termination mechanism of event-files remains unclear, with a common assumption involving distal action effects.

Purpose of the Study:

• To investigate whether distal action effects (visual, auditory) terminate event-files.
• To determine the influence of distal action effects on stimulus-response (S-R) binding.
• To clarify the role of action-effect registration in event-file termination and retrieval.

Main Methods:

• Utilized a stimulus-response (S-R) binding task.
• Compared three action-effect conditions: no distal effect, visual effect, and auditory effect.
• Assessed S-R binding effects across these conditions.

Main Results:

• No significant modulation of S-R binding effects was observed across the different action-effect conditions.
• Large binding effects were consistently found regardless of the presence or type of distal action effect.
• This indicates distal action effects do not play a crucial role in terminating event-files for retrieval.

Conclusions:

• The findings challenge the assumption that distal action effects terminate event-files.
• Proximal action effects might be sufficient for event-file termination, independent of distal feedback.
• Current models of action control require refinement regarding the mechanisms of event-file termination and their impact on S-R binding.
