Description
Learning Chapter 7 April 2 – next mid-term Chapter 7 &8 On the exam: He will give an example and we have to identify the Unconditioned responses, CS, etc. CS (will elicit something like an unconditioned response) – neutral – could be anything, bell, light (after pairing with the UCS it takes on new properties with association) Unconditioned – no training is involved – automatic UCS leads to UCR After a few experiences the dogs became aware by the sound of the bell that they would get fed and began salivating making the UCR become a Conditioned Response (CR) – training has occurred or is occurring Freud thought bed wetting was the child having hostility and anger towards their parents - Form of revenge Bed Wetting – bell and blanket method CS – weak bladder tensions You want to condition the child to wake when there are bladder tensions CR – the child wakes when they have to go to the bathroom It is believed that our complex life can be seen as simple – and conditioned and changed - Within us we have the power to change on our own – its our decision - Environmental cues start the dogs salivation - E.g. rehabs and are not like the environment where people do drugs or drink – because that reduces the environmental cues - Environment supports the habit Pavlovian - Respondents - Elicited– the response is elicited by the lab and cues - Classical - Operant -operant b/c you operated based Skinner - Instrumental – elicited a response In common - Acquisition of response (it takes time and trials the acquisition increases – over time the bell elicits more salvia over time) o The CR develops under the condition of reinforcements CS – UCS (over and over) o The CS is always presented first (called forward conditioning)  How the organism forms a UCR - Simultaneous UCS and CS overlap – gets confusing - Backward conditioning – the UCS occurs than the CS (no evidence that this works) - Trace Conditioning – the CS goes off and then the UCS goes on the UCS occurs in the absence of o Traces of the CS e.g. Pavlov turning the light off then feeding the god Semantic Conditioning – See, Land, Ocean Extinction – extinction of a CR - When you present the CS alone, your graph line goes down to the right - Over time the dogs stopped salivating to the bell, etc. - After extinction, there was a little bit of salivation response and Pavlov called it ‘spontaneous recovery of a conditioned response’ o Can recondition if reinforced – can be done quickly - Stimulus Generalization o Means that stimuli closely related to the condition – you will make a response to that o Stimuli closest to the training stimuli elicit the strongest response o E.g. a boy who is bitten by
