PSYS 371 Unit 3 Notes Stimulus Discrimination vs. Stimulus Generalization Doing the right thing at the right time Stimulus (Stimuli) What Stimulates You? o Music, light, smells, colors Under what conditions are you stimulated? o All music? All smells? All colors? What is it about those conditions that stimulates your behavior? Stimulus Control What is the relationship between the stimulus (i.e. “what stimulates you”) & the response (i.e. your behavior) To what degree is your behavior governed (i.e. controlled by) the stimulus? o Relates to feeling of true love o Relates to impulse control/ anger management Stimulus Discrimination (AKA: NOT NOW!!!!) What prompts you to do that behavior & when. Two types of controlling stimuli (discriminative stimuli) o S(d): stimulus for reinforcement (i.e. GO, “do it!”) Ex: nod, smile, thumbs up o S(^): “delta,” stimulus of extinction (i.e. STOP, “don’t do it!”) Ex: cut it out, short responses, glare Can stimuli be both S(d) & S(^)? o YES!!!! o A sign that says “men” on a restroom door is an S(d) for men & and S(^) Teaching stimulus discrimination o Discriminate the place, time, & people that the behavior is appropriate with Stimulus Generalization (AKA: CAN I DO IT NOW?) Knowing how & when to respond to 2 different stimuli How do you know when to respond the same way to 2 different stimuli? o Ex: a poodle/ a great dane (both dogs), waving & telling “come here” 3 Types of Stimulus Generalization o Generalization due to Physical Similarity (close enough you can figure it out) Ex: mac vs. pc, driving a Toyota vs. a Ford o Generalization due to Common Characteristics Ex: red ball vs. red pen, snow & rain o Generalization due to Equivalence Class 3 vs. three vs. III o Teaching stimulus generalization It’s ok to do something in one place, but is it ok to do it at another place? Ex: no pda in public Shaping, Fading, Chaining, Tokens Shaping (Chapter 7) What is shaping? – Getting a new behavior to happen o Initiating a new behavior o Reinforce “successive approximation” of target behavior Work towards goal Little by little reinforcing small reinforcers working towards end goal What is meant by “successive approximation?” o Reward any behavior in closer approximation to target than last behavior. Work to criterion. Example: running a marathon Dimensions of behavior that can be shaped o Topography (whole form of the behavior “brushing teeth) o Amount (frequency/ duration) Latency (time inbetween) Increase time period over time Ex: time they do behavior with time they get reinforcer o Intensity Hardest one More important than frequency Shaping Procedures “What is the behavior you want to see in the end goal?” o Specifying the final desired (terminal) outcome/ behavior o Choose a starting behavior o Choose shaping steps (list successive approximations) Reinforcer at end of each step o Select reinforcers o Reinforcer after each success Watch for under/over reinforcement. Why? Too much reinforcement = no motivation (response will decrease) o Move along at the correct pace (prior step completed to criteria) Fading (Chapter 10) What is fading?Reduction of prompting, The fading withdraw of the controlling stimulus o Gradual withdrawal or modification of controlling stimulus o Remember this!!! Fading is the Reduction of Prompt Levels!!! o Controlling stimulus: what is it that prompts the behavior? Guidelines for fading: how much prompting do you want? o Identify the plans throughout the whole process o Start by knowing where you want to end o Choose final desired stimulus Be specific o Select an appropriate reinforcer It’s only a reinforcer if it works o Choose the starting stimulus & fading steps Specify all conditions; specify dimensions; outline steps for moving to next level; address error plan; address weaning plan o Put plan into action
