PSY397H5 Lecture Notes - Lecture 3: Fear Conditioning, Neuroplasticity, Wild Type
Document Summary
Cue test: graphs: animal has now produced fear towards the tone cue. Fear conditioning: foreground and background: background cue- things in the background that are non-unique, white noise in the back that doesn"t change and has always been there, foreground- things that are new, ex: new person in a room. Conclusion: memory and learning cannot be tested directly, can only conclude about memory, only measured movement and measured freezing, did not measure memory. Passive avoidance paradigms: nocturnal animals don"t like the light phase- induced fear, other side (dark side) exposes them to a shock, scientists measure the latency to go over to the dark side. Active avoidance paradigm: they need to learn to avoid shock by switching room when they hear the tone. Morris maze: best measure: cumulative distance from start point is used for spatial accuracy. Icr vs. cd1 graphs: cd1 can nd platform very quickly (learn very quickly, icr mice cannot nd platform.
