Dr. Park replicates Tolman's classic maze studies with three groups of rats. Group A receives food at the goal box every trial. Group B never receives food. Group C explores the maze for 10 days with no reward, then on day 11 begins receiving food. Within two trials after reinforcement begins, Group C's error rate drops to match Group A's, far below Group B's.
A separate experiment shows chimpanzees suddenly stacking boxes to reach a banana after a period of inactivity, replicating Köhler. Compared with latent learning, this insight learning is best distinguished by which feature?
- A
A reliance on partial reinforcement to shape behavior
- Bcheck_circle
A sudden, all-or-none restructuring of the problem rather than gradual map-building
- C
A dependence on observational learning from a model
- D
An automatic response triggered by classical conditioning
Explanation
Köhler's insight learning involves a perceptual reorganization producing a sudden solution, whereas latent learning involves gradual, unrewarded acquisition revealed later.
