HIS282Y1 Chapter Notes -Substantia Nigra, Tegmentum, Latent Inhibition
Document Summary
Many types of conditioning, some are more meaningful than other ones. Cs light or tone, us: reward or shock, = delayed conditioned. Conditioning occurs most rapidly when the cs and us are new/novel to the subject. Prior exposure to the stimuli can interfere with learning latent/retarded inhibition animal models for schizophrenia (stimulus is not very relevant so you don"t pay attention) Intensity of cs and us also affect condition more intense = better, not too much! Some stimuli are more readily associated w/ one another than others? i. e. tastes and illness? (good) tastes ad sounds? (not really) smell and shock? (no) sounds and shock? (yes) Internal stimuli go together, external stimuli go together. Animals attribute a particular effect (fear, illness) with its most probably cause, based on past experience/evolutionary history. Much easier to establish aversion to bitter or our tasting substances to sweet ones. Monkeys and fear of snakes vs. fear of flowers.
