AP Psychology Unit A: Learning Theories
Cognitive Map
- Definition: A cognitive map is a mental representation of the physical layout of an environment.
- Origin: This concept was introduced through the maze studies conducted by Edward Tolman, demonstrating that organisms can learn complex spatial layouts without direct reinforcement.
Continuous Reinforcement
- Definition: Continuous reinforcement refers to providing reinforcement every single time a desired response occurs.
- Effect: This reinforcement schedule leads to high rates of learning, as the behavior is consistently reinforced each time.
Edward Tolman
- Contribution: Edward Tolman was a psychologist known for his work in the field of learning and motivation.
- Key Concept: He emphasized the cognitive aspects of learning, particularly through his research on cognitive maps and latent learning.
Fixed Interval Schedule
- Definition: A fixed interval schedule is a reinforcement schedule where the first response after a predetermined set time period is reinforced.
- Outcome: This schedule produces a distinctive "scalloped" pattern of response rates, as organisms tend to respond more as the time for reinforcement approaches.
Fixed Ratio Schedule
- Definition: This reinforcement schedule involves providing reinforcement after a set number of responses have been made.
- Example: Commonly illustrated by piece-work pay systems, where workers are paid after completing a specific number of items.
Latent Learning
- Definition: Latent learning is a form of learning that is acquired without any explicit reinforcement and is only revealed when an incentive is present.
- Application: This concept suggests that learning can occur even without direct rewards, changing the traditional views of operant conditioning.
Learned Helplessness
- Definition: Learned helplessness is a psychological condition characterized by hopeless resignation that develops after repeated exposure to uncontrollable aversive events.
- Originator: This concept was introduced by psychologist Martin Seligman who studied animals subjected to uncontrollable shocks.
Martin Seligman
- Contribution: Martin Seligman is known for his research on learned helplessness and its implications in psychology, particularly in understanding depression and resilience.
Partial Reinforcement
- Definition: Partial reinforcement occurs when only some correct responses are reinforced.
- Impact: This schedule results in slower learning compared to continuous reinforcement but leads to strong resistance to extinction, as the behavior is less predictable.
Superstitious Behavior
- Definition: Superstitious behavior arises when an irrelevant act is accidentally paired with reinforcement or punishment, leading the individual to believe the act has a causal effect (e.g., a “lucky” pen).
Variable Interval Schedule
- Definition: A variable interval schedule provides reinforcement after varying time intervals.
- Characteristics: This results in slow and steady responding, with unpredictable pauses in behavior.
Variable Ratio Schedule
- Definition: A variable ratio schedule involves providing reinforcement after an unpredictable number of responses.
- Outcome: This schedule produces the highest and steadiest rate of responding among all reinforcement schedules, as the individual cannot predict when the next reinforcement will occur.
