Short-term habituation vs long-term habituation Same exact behavior for very different reasons Short-term habituation: less reaction time because the calcium channels are getting smaller and less calcium is coming in Long-term habituation: less reaction because there are a lot less synapse connections Associative learning ? learning takes place by associating between 2 or more stimuli Why do some stimuli Contiguity: close in time Similarity: two things that are similar will connect together Intensity: Frequency: the more often something happens the more likely Unconditioned stimulus: a stimulus that innately and involuntarily elicits a reflexive response Unconditioned response: the reflexive response of an unconditioned stimulus Conditioned stimulus: following pairings with an US a neutral stimulus can come to control a new response Conditioned response: Sensory imput ???. Motor/behavior output Painful stimulus fear response Sound orienting response Food appetitive response Member opposite sex sexual response Controls? what to compare the conditioned animal to? A naïve dog (within or between design) A CS control group (bell only) A US control group (meat only) A group with CS?s and US?s presented randomly Extinction trials: presenting the CS (bell) without the US (food) The strength of the conditioned responses can be quantified The magnitude of the CR compared with the UR
