PSY105 Modules 20-22: Learning
Question | Answer |
---|---|
what is associate learning | process of connecting simultaneous or sequential events (conditioning) |
What is cognitive learning? | required the acquisition of mental information to guide our own behavior. |
observational learning | Watch and learn (social learning) |
Explain the difference between classical conditioning and operant conditioning | Classical conditioning: Involves linking 2 or more stimuli. (Dog salivating when they hear a bell ring) Operant conditioning: involves and organism associating a behavior or action w/ a consequence. (rewarding a rat for pressing a button: Skinner box) |
Example of unconditioned stimulus | Food |
Example of unconditioned response | Salvation |
Example of conditioned stimulus | Bell |
Example of conditioned response | Salvation |
Explain law of effect | rewarded behavior increases and punished behavior decreases. |
What is positive reinforcement? | rewarding a desired behavior w/ pleasurable stimulus |
what is negative reinforcement? | encourages a response by removing something negative, desired behavior is utilized to avoid something aversive. |
What is primary reinforcers? | rewarding/ don't need to be learned or associated. |
Conditioned reinforcers? | Must be learned/associated |
Reinforcement schedules | have a significant influence on how effective and long-lasting reinforcement is. |
Continuous reinforcement schedules | result in rapid learning, but behavior extinction (the desired behavior diminishes and eventually stops) also occurs rapidly. |
Fixed-ratio schedules | reward the desired behavior after a set number of responses. |
Variable-ration schedules | reward the desired behavior after a different number of response every time, making the reward unpredictable. This results in a high response rate because the more responses that occur, the more rewards are given. |
Intermittent reinforcement schedules | reward the desired behavior irregularly. Learning occurs more slowly but is much more stable in the long-term. |
Fixed-interval schedules | reward the desired behavior after a set duration of time. The desired behavior tends to increase around the time the reward is due. |
Variable-interval schedules | reward the desired behavior on a changing time schedule |
Explain instinctive drift | Tendency for old behaviors to revert back to behaviors that are more instinctual |
