A comparison of concurrent and retrospective verbal protocol analysis
The American Journal of Psychology
|September 21, 2000
Summary
Concurrent verbal protocol analysis, which records thoughts during decision-making, is more effective than retrospective analysis for understanding human decision processes. Concurrent data provides deeper insights into decision steps, though retrospective data offers more final choice explanations.
Area of Science:
- Cognitive Psychology
- Human-Computer Interaction
- Decision Science
Background:
- Verbal protocol analysis is a key method for studying decision-making.
- Data can be collected concurrently (during) or retrospectively (after) decision-making.
- Empirical comparisons of these data collection methods are lacking.
Purpose of the Study:
- To empirically compare the effectiveness of concurrent and retrospective verbal protocol analysis.
- To determine which method better reveals the human decision-making process.
- To identify the unique advantages of each data collection approach.
Main Methods:
- A comparative study design was employed.
- Human decision-making processes were analyzed using both concurrent and retrospective verbalization.
- The quantity and quality of insights from each method were evaluated.
Main Results:
- Concurrent verbal protocol analysis yielded a higher number of elicited protocol segments.
- Concurrent data offered richer insights into the intermediate steps of decision-making.
- Retrospective protocols provided more statements specifically about the final choice.
Conclusions:
- Concurrent verbal protocol analysis is generally superior for capturing the dynamic decision-making process.
- Retrospective verbal protocol analysis has value for understanding final choice justifications.
- The choice of method should consider the specific research questions regarding decision-making.
