Flexible and inflexible response components: a Stroop study with typewritten output.

Area of Science:

• Cognitive Psychology
• Human-Computer Interaction
• Experimental Psychology

Background:

• Investigating the relationship between response selection and execution in typewriting.
• Examining the extent of concurrent processing during skilled typing tasks.

Purpose of the Study:

• To determine if response execution is structurally segregated from earlier cognitive processing stages.
• To understand how cognitive interference, like Stroop effects, impacts typing performance.

Main Methods:

• Utilized a Stroop paradigm adapted for typewriting responses.
• Participants typed color names with varying distractor congruency and stimulus-onset asynchronies.
• Measured initial keystroke latencies, errors, and response durations under different time pressures.

Main Results:

• Stroop interference and facilitation affected initial keystroke latencies and errors.
• Response durations, a measure of response execution, remained unaffected by Stroop manipulation.
• All measures responded to time pressure, but Stroop effects were limited to latencies and errors.

Conclusions:

• Response execution appears to be structurally segregated from earlier processing stages in typewriting.
• Alternatively, response encapsulation may develop during the acquisition of typing skills, protecting execution from interference.
• Findings suggest distinct processing stages in skilled motor tasks like typing.
