Document Summary

Life without memory equals no sense of existing across time. Conditioned stimulus + unconditioned stimulus -> unconditioned response; after: cs-> cr. Eg. cs (sound) + ucs(food) -> ucr (salivation); with pairings: cs (sound) -> cr(salivation) Operant conditioning: response -> reinforcer (increased % of response) or punishment (decrease % of response. Operant conditioning: response determines outcome; classical: cs/ucs occur regardless of behavior. Pavlov: cc(class. cond. ) reflects increase in cs+ucs centre in brain. Lashley: looking for an engram (physical representation of what"s learned) Lashley: cut portions of brain to sever connections, but, did not affect rat"s memory, Look for engram in cerebellum; wanted to see if blocking brain areas stops learning. Found: blocking lip (lateral interpositus nucleus) stopped rabbit from responding to ucs or cs. Found blocking other areas (eg. red nucleus) don"t have same effect; thus: lip is necessary for learning. Difference between learning (new knowledge) and memory (remembering), but need both.

So far Ralph is disappointed because his dog is not learning to salivate at the sound of the clicker. The reason why the dog is not learning is that A) the 5 second delay is too long B) the clicker should be activated after he feeds the dog C) the dog is learning, but its performance does not yet reflect it D) it is only possible to train dogs with operant conditioning E) there is not enough information given to determine why the dog is not learning
