| Question | Answer |
|---|---|
| What is learning? | A persistent change in bahavior resulting from repeated practice or experience which includes interaction of both behavior and environment |
| How does performance relate to learning? | Performance is usually how learning is assessed. |
| What is state-dependent learning? | Laerning is influenced by a person's internal state or the external environment in which the information was first acquired. |
| What is the difference between habituation and sensitization? | H: leads to diminished reflexive response, S: leads in increased reflexive response |
| Define the CS, CR, UCS, UCR: | UCS: "natural" reward/response. CS: introduced signal paired with UCS. UCR: "natural" response to UCS. CR: when UCR is given in response to CS. |
| What is extinction in classic conditioning? | CS repeated w/out UCS -> CR disappears |
| What is stimulus generalization in classic conditioning? | CR produced in response to similar but not identical stimuli |
| What is discrimination in classic conditioning? | CR produced by CS but NOT a similar stimulus (opposite of generalization) |
| What is aversive conditioning? | associate unwanted behavior w/painful stimulus to eliminate behavior |
| Define Operant conditioning | Learning as a result of the consequences of voluntary actions |
| What is the difference b/tw fixed ratio & variable ratio reinforcement? | Fixed Ratio: reward after every nth response -> uniform rapid response, fast extinction. Variable Ratio: reward after variable |
| What is the difference b/tw Fixed Interval & Variable Interval reinforcement? | Fixed Interval: reward after set amt TIME, more responses just prior to reward & less just ater, rapid extinction. Variable Interval: reward after variable amt time passes, uniform response rate, resistant to extinction. |
| What is the difference b/tw + & - reinforcement & punishment? | (+) Reinforcement: reward of behavior increases prob of behavior. (-) Reinforcement: Behavioral response = removal of aversive event. Punishment: Aversive Stimulus + Undesired response (to weaken). |
| What is cognitive learning? | Cognitive Learning: using intellectual knowledge (obtain/organize/use). |
| What is Beck's Cognitive Triad of Depression? | 1) bad view of self, 2) bad interpretation of experiences, 3) bad expectations of future |
| What is the difference between modeling & shaping? | Modeling = learn via observe & imitate (works when identify w/role model; need confidence that can learn behavior). Shaping = Reward behaviors close to desired behavior. |
| What is cognitive learning? | obtain/organize/use knowledge. Must predict consequences, cause & effect. Interaction of thoughts, feelings, behavior. |
| What are examples of cognitive strategies? | Mental plans used to understand self in environment: 1) Beck's Cognitive Triad of Depression, 2) Piaget, 3) Therapeutic instruction, 4) Self-monitor, 5) Set goals |
| What are Prochaska & DiClemente's Stages of Change? | 1) Pre-contemplate (encourage, discuss), 2) Contemplate ("") , 3) Prepare (obstacles, social, benefits, plan), 4) Act (use social&plan, yay success, anti-stress), 5) Maintain & Prevent Relapse (reward & benefits), 6) Relapse (why? revise plan, move on) |
