Why do we need the cognitive level in addition to the psychological level?

• A. Because some explanations require the language of information processing
• B. To explain brain chemistry
• C. To describe purely statistical models
• D. To replace psychology

Answer: (A)

We need the cognitive level because it provides a language for describing the mind as an information-processing system—how stimuli are encoded, transformed, and turned into responses. This perspective makes explicit the mental operations and the sequence of steps people use to complete tasks, such as encoding input, keeping information in working memory, and retrieving it to act. It also offers concrete, testable predictions about things like reaction times, error patterns, and strategy use, linking behavior to the underlying processing mechanisms. Brain chemistry explains biology, not processing steps; purely statistical models describe data patterns without detailing cognitive operations; and replacing psychology would ignore important mental processes that influence behavior.
