The Specificity and Reliability of Conflict Adaptation: A Mouse-Tracking Study

Area of Science:

• Cognitive Psychology
• Neuroscience
• Human Behavior

Background:

• Conflict adaptation effects, also known as sequential congruency effects (SCEs), are a widely cited phenomenon in cognitive psychology.
• Recent research questions the reliability and specificity of SCEs, particularly across different tasks like the Flanker and Stroop.
• This has led to challenges against dominant models of cognitive control.

Purpose of the Study:

• To investigate if domain-general processes underlying SCEs are detectable using sensitive mouse-tracking metrics, rather than solely relying on reaction times.
• To examine the relationship between SCE effects in the Stroop and Flanker tasks for the first time using a mouse-tracking paradigm.

Main Methods:

• Employed a mouse-tracking paradigm to analyze the Stroop and Flanker tasks.
• Examined both group-level SCEs and within-task split-half reliabilities.
• Correlated SCEs across tasks using overall reaction times and dynamic mouse-tracking measures.

Main Results:

• Robust group-level SCEs were observed for both the Stroop and Flanker tasks.
• Within-task reliabilities for SCEs were generally weak or non-existent.
• While reaction times showed no correlation in SCEs between tasks, mouse-tracking measures revealed significant cross-task correlations.

Conclusions:

• Mouse-tracking provides a more sensitive measure for detecting domain-general processes related to conflict adaptation than traditional reaction times.
• The findings suggest that mouse-tracking can help reconcile the reliability and specificity of SCEs across different tasks.
• This methodology offers a promising avenue for future research to differentiate between theoretical models of cognitive control.
