PS261 Lecture Notes - Lecture 4: Interstimulus Interval, Classical Conditioning, Schizotypy
Document Summary
Excitatory pavlovian conditioning procedures: timing, 5 conditioning trials, sessions, trials, intertrial interval, interstimulus interval. Measuring conditioned responses doing test trials: magnitude, probability of responding, latency. Control procedures of classical conditioning (avoid pseudo-conditioning: random control procedure, explicitly unpaired control. Introduce an excitatory conditioning paradigm: present the cs+ with a cs-, a conditioned inhibitory. Latent inhibition effect: repeated presentation of the cs by itself (pre-exposure phase, same cs is presented with us using classical conditioning, the pairing is slower, over inclusiveness, schizophrenia schizotypy creativity. Us preeexposure effect even the us works better if its novel: present us by itself, try using it in classical conditioning, pairing is slower. A stimulus is presented with no consewuence. It becomes a distraction and is thus ignored. It is then preented again with a reward. Because it was a distractor, it takes longer to associate it with the reward. Example: annoying beeping noise, how annoying!
