Step 1: Define reaction time
Reaction time is a measure of the time taken to respond to a stimulus. It is a quantitative, objective measure frequently used in psychology, psycholinguistics, and cognitive science research.
Step 2: Identify relevant methods
(A) Behavioral methods — Yes, reaction time tasks (like lexical decision tasks, Stroop tests) are core behavioral measures. ✔
(B) Experimental methods — Yes, reaction time is often measured in controlled lab experiments to test hypotheses about cognition and language processing. ✔
(C) Non-behavioral methods — Incorrect; these involve observation, archival analysis, or non-performance measures. ✘
(D) Qualitative methods — Focus on descriptive data (interviews, ethnography), not numerical measures like reaction time. ✘
Therefore, reaction time is specifically tied to behavioral and experimental methods.
