Cognitive interviews (CIs) and think-aloud protocols (TAPs) enhance understanding of participant thought processes. These methods aid researchers in refining instruments and interventions by making cognitive processes explicit.
Area of Science:
- Cognitive science and educational research methodologies.
Background:
- Cognitive interviews (CIs) and think-aloud protocols (TAPs) are qualitative methods to elicit participant thought processes.
- Understanding participant cognition is crucial for developing effective instruments and interventions.
Purpose of the Study:
- To describe the origins, applications, and implementation strategies of CIs and TAPs.
- To highlight the utility of CIs and TAPs in pharmacy education research.
Main Methods:
- CIs involve targeted questions to assess comprehension during tasks.
- TAPs require participants to verbalize their thoughts while performing a task.
Main Results:
- Both CIs and TAPs make cognitive processes explicit, aiding in understanding problem-solving and comprehension.
- Verbal reports from CIs and TAPs can be analyzed using qualitative and quantitative methods.
Conclusions:
- Choosing between CIs and TAPs depends on the research aim and requires careful participant selection and preparation.
- CIs and TAPs are valuable tools for pharmacy education researchers to improve survey construction, study test response processes, and map cognitive models.

Cognitive Learning
E. C. Tolman's theory of purposive behavior emphasizes that much behavior is goal-directed. He argued that to understand behavior, we must look at the entire sequence of actions leading to a goal. For instance, high school students study hard, not just due to past reinforcement but also to achieve the goal of getting into a good college.
