Document Summary

Reduced responding to a stimulus that becomes familiar. Ex: you get used to the feeling of wearing clothes. Persistent strengthening of synapses based on recent patterns of activity. Strengthening neural connection = neurons are better at firing. Learning takes longer: temporal conditioning: cs doesn"t need to be an actual event, Can be passage of time: establishing associations, contiguity: cs and us are close in time, contingency: cs is predictive and apart from events that are constant or intermittent, learning requires contiguity, not contingency, stimulus-response association (sr-as): Dogs were not salivating because of the ball but because of what comes after the ball: phenomena, acquisition: Learning things that have a real association. Response is first established and gradually strengthened. Behavior is lost because of lack of pairing of us and cs. Conditioned response is lost: spontaneous recovery: After extinction, a lost behavior can come back. Have to wait a while in between.
