Errors in simple choice tasks stem from response speed or evidence quality, leading to distinct post-error adjustments. This study reveals how these different error types influence subsequent performance, impacting cognitive control measures.
Area of Science:
- Cognitive Psychology
- Neuroscience
- Decision Making
Background:
- Errors in simple choice tasks systematically alter response time and accuracy in subsequent trials.
- Existing theories often overlook the diverse origins of choice errors and their differential impact on cognitive processes.
Purpose of the Study:
- To investigate if different causes of choice errors (response speed vs. evidence quality) produce distinct post-error changes.
- To explore the implications of these findings for understanding and measuring cognitive control.
Main Methods:
- Two recognition memory experiments were conducted.
- Participants completed tasks under speed-emphasis and accuracy-emphasis conditions to elicit specific error types.
Main Results:
- Response-speed errors were associated with traditional post-error slowing.
- Evidence-quality errors were linked to post-error speeding.
- Differential post-error adjustments were observed based on the error's cause.
Conclusions:
- Choice errors can arise from distinct mechanisms, namely response speed and evidence quality.
- Post-error changes are not uniform and depend on the error's underlying cause.
- Cognitive control theories should be broadened to include both adaptive and maladaptive strategies, considering the nuances of post-error adjustments.

Types of Errors: Detection and Minimization
Absolute error in a measurement is the numerical difference from the true or central value. Relative error is the ratio between absolute error and the true or central value, expressed as a percentage.
Errors can be classified by source, magnitude, and sign. There are three types of errors: systematic, random, and gross.

Systematic Error: Methodological and Sampling Errors
Sampling errors originate from improper sampling methods or the wrong sample population. These errors can be minimized by refining the sampling strategy. Defective instruments or faulty calibrations are the sources of instrumental...
