Final answer:
Edward Titchener, a student of Wilhelm Wundt, implemented the method of introspection to understand the mind's structure in psychology, which is called structuralism.
Step-by-step explanation:
The individual who asked people to report about their sensory experiences to understand the mind was C) Edward Titchener. Titchener was a student of Wilhelm Wundt and went on to develop structuralism, which argued that our cognitive experience is best understood by analyzing the experience into its component parts, primarily through a method called introspection.
This approach aligned with Wundt's belief that psychology should break down conscious experience into its basic elements. Unlike behaviorists like John Watson, who refocused psychology on observable behavior, or William James, who emphasized functionalism, Titchener sought to catalog the elements of the mind's structure.
