Representation
Ask what information must be encoded for a task to be performed and how that representation constrains behavior.
Subject
Purpose
Mental processing studied through attention, memory, language, reasoning and decision tasks that infer representations from behavior.
Structure
Entities → interactions → mechanisms → scales → measurement
Cognitive psychology builds models of internal processing by manipulating information and measuring errors, timing and choices rather than directly observing thoughts.
Ask what information must be encoded for a task to be performed and how that representation constrains behavior.
Study selection, interference and executive control through limited-capacity tasks and competing demands.
Separate encoding, storage and retrieval while distinguishing working, episodic, semantic and procedural functions.
Use problem-solving and decision tasks to test algorithms, heuristics and representational limits.
Compare process models by their quantitative predictions, error patterns and transfer across tasks.
reaction time ≠ one cognitive process
task performance ≠ single ability
model fit ≠ mechanism proven
What behavioral signature would distinguish two competing process models?
Which laboratory tasks measure a general process versus task-specific strategy?
How should cognitive models change when neural evidence conflicts with behavioral interpretation?
Experimental manipulation and model comparison carry more weight than task labels; replication and converging paradigms are needed before treating a measure as a stable cognitive construct.
