Shepard and metzler measured the time it took for participants to decide whether two objects were the same (two different views of the same object) or different (two different objects). these researchers inferred cognitive processed by using
a. image scanning. b. mental chronometry. c. epiphenomena. d. propositional representations.

The correct answer is B. mental chronometry

Explanation:

Mental chronometry is the study in which reaction and response time while performing perpetual motor tasks are used to infer the cognitive processes. The task used in mental chronometry study are quite simple and is studied by evaluating the reaction time.

In this question, Shepard and Metzler measured the time it took for participants to decide whether two objects were the same (two different views of the same object) or different (two different objects) which shows that the response time of participants are measured therefore these research inferred cognitive processed by using mental chronometry.
