Learning from mistakes: Incidental encoding reveals a time-dependent enhancement of posterror target processing

Area of Science:

• Cognitive Psychology
• Neuroscience
• Human Memory

Background:

• Post-error adjustments in cognition are known but poorly understood.
• Traditional performance metrics are insensitive to trial-specific processing changes.
• The adaptive orienting theory proposes error-driven inhibition followed by attention retuning.

Purpose of the Study:

• To investigate trial-specific post-error cognitive adjustments.
• To test the adaptive orienting theory of post-error processing.
• To examine the temporal dynamics of post-error effects on memory encoding.

Main Methods:

• A novel object flanker task with unique stimuli and surprise recognition memory test.
• Manipulation of response-stimulus interval (RSI) across four experiments (300 ms, 650 ms, ~1,000 ms).
• Analysis of incidental encoding of target and distractor stimuli following errors versus correct responses.

Main Results:

• Errors significantly enhanced subsequent target memory by ~10%, but not distractor memory.
• This posterror enhancement of target encoding (PETE) was dependent on the response-stimulus interval (RSI).
• PETE was observed at longer RSIs (650 ms, ~1,000 ms) but not at the short RSI (300 ms).

Conclusions:

• Findings support the adaptive orienting theory of post-error processing.
• Demonstrates a novel, time-dependent cognitive phenomenon: posterror enhancement of target encoding (PETE).
• Highlights the importance of trial-specific measures and temporal dynamics in understanding cognitive control.
