ThinkAloudStudien

ThinkaloudStudien are research studies that employ the think-aloud protocol, in which participants verbalize their thoughts while performing a task to reveal cognitive processes underlying decision making, problem solving, or task execution. The approach is widely used in human-computer interaction, education, cognitive psychology, and related fields to gain access to processes that are typically not observable.

In practice, a participant performs a task while continuously speaking about their thoughts, actions, and judgments. There are two main variants: concurrent think-aloud, where verbalization happens during task performance, and retrospective think-aloud, where statements are produced after the task based on memory. Data collection usually involves audio or video recordings and transcripts, which may be enriched with eye-tracking, screen recordings, or action logs. Data are analyzed through protocol analysis or qualitative coding to identify reasoning strategies, problem-solving steps, and error sources. The approach has roots in the work of Ericsson and Simon and later developments in protocol analysis, which involve constructing a record of thought processes from verbal data.

Applications of ThinkaloudStudien include usability testing, to identify interface problems and cognitive load; education and training design, to improve instruction and feedback; and cognitive research, to study problem solving and decision making. Strengths of the method include access to implicit processes and rich qualitative data. Limitations include reactivity, the potential for incomplete verbalization, and the time required for transcription and coding. Ethical considerations involve informed consent, privacy, and careful handling of sensitive information.
