Document Summary
Preference learning: being exposed to different stimuli may make us like them more, stimuli used are those that are unfamiliar to subject so they don"t have pre- existing preferences, subjects not aware of why they have preference. You don"t know why you like it better. Mere-exposure effect: mere exposure to abstract paintings increases preference for them, you prime it, easier for you to process. Pavlovian conditioning: cs and us paired together, through pairing, the previously neutral stimulus (cs) becomes a powerful emotion, fear is usually used since it is a powerful emotion. Fear depends on hippocampus, but fear conditioning to a tone or light does not damage to amygdala will not have response. Damage to hippocampus will still have response. Fear is important to animals: when they see cues, they have a conditioned response of freezing. Amygdala is really important for fear: sensory input to sensory thalamus, sometimes doesn"t need cortical processing, low road, go directly to amygdala.
