The Slip Induction Task: creating a window into cognitive control failures.

Area of Science:

• Cognitive Psychology
• Neuroscience
• Human Factors Engineering

Background:

• Action slips, or "what was I thinking?!" moments, frequently occur during routine, multi-movement tasks.
• Existing research often focuses on response conflict within single movements, not complex action routines.
• Understanding action slips in real-world tasks is crucial for improving performance and safety.

Purpose of the Study:

• To introduce and validate the Slip Induction Task (SIT) for inducing action slips in well-learned movement routines.
• To investigate the conditions under which action slips are reliably induced in sequential actions.
• To examine the cognitive and behavioral consequences of avoiding action slips during routine tasks.

Main Methods:

• Development of the Slip Induction Task (SIT) to present unexpected cues during established movement sequences.
• Systematic manipulation of cue predictability and target location to elicit response conflicts.
• Measurement of action slip occurrence and reaction time/movement speed.

Main Results:

• The SIT reliably induces action slips in participants performing routine movement sequences.
• Action slips are more frequent when unexpected cues require movement to a novel target location.
• Avoiding an action slip, even when successful, leads to a measurable decrease in movement speed.

Conclusions:

• The Slip Induction Task (SIT) provides a valid method for studying action slips in ecologically relevant movement routines.
• Unexpected cues, particularly those directing action to new locations, are potent triggers for action slips.
• Performance adjustments to prevent action slips incur a speed-related cost, highlighting a trade-off between accuracy and efficiency.
