Observations on the microstructure of response conflict

Area of Science:

• Cognitive Psychology
• Psychophysiology
• Human Factors

Background:

• Response conflict is typically assessed using reaction time (RT) measures.
• Physiological measures have previously shown partial activation of competing responses.

Purpose of the Study:

• To evaluate the frequency of double responses (DRs) as a novel indicator of response conflict.
• To compare the utility of DRs with traditional RT measures in detecting response conflict.

Main Methods:

• Three experiments were conducted to analyze response patterns.
• The frequency of double responses (DRs) was recorded and analyzed.
• Reaction time (RT) was measured concurrently with DRs.

Main Results:

• DRs occurred most frequently under conditions predicted to elicit response conflict.
• The frequency of DRs correlated with RT changes indicative of conflict.
• DRs represent a measurable index of response conflict, similar to physiological measures.

Conclusions:

• The frequency of double responses (DRs) is a useful and easily implemented indicant of response conflict.
• DRs provide an alternative or complementary measure to RT for assessing cognitive conflict.
• This finding advances the understanding of response dynamics and conflict monitoring.
