Document Summary

Factor 1 - pavlovian fear conditioning shock (us) ------> fear (ur) tone (cs) - Factor 2 - reinforcement through fear reductiontone (cs) -----> fear (cr) Avoidance response ---> termination of tone (cs) = reduction of fear (cr) the animal learns to fear but the reinforcement is the reduction of fear. What you are removing here is the fear and increasing the frequency of the behavior that does not remove it. What you are really trying to avoid is an emotion to a particular stimuli. This is the case for drug addiction as well. > animals do not appear to display fear. Operant conditioning occurs and a there a cognitive aspect in wondering why the behavior continues due to expectations. Escapable shocks inescapable shocks no shock not much training. Escape training - 74% learned escape training - 28% learned escape training - When you run to the other side, the shock is still there.
