PSYCH 1X03 Chapter Notes - Chapter 1: Homeostasis, Drug Withdrawal, Classical Conditioning
Document Summary
Drug tolerance: decreased effectiveness of a drug such as morphine over the course of repeated administration. Orienting response: automatic shift of attention toward that stimulus or event. Habituation: decrease in response to a stimulus or event as it is repeatedly presented without any consequence. Dishabituation: increase in responding that follows a change in the stimulus to which habituation has occurred (sound of birds chirping). Sensitization: increase in response to a stimulus or event as it is repeatedly presented. Can be adaptive as it prompts you to engage in behaviours appropriate to escaping a potentially harmful stimulus (being poked during a horror movie). Associative learning: learn relationships between stimuli and events. Continguinity: the extent to which the unconditioned and conditioned stimuli occur together in time and space. Excitatory conditioning: presence of the cs predicts the presence of the us. Higher-order conditioning: stimulus that was previously neutral is paired with the cs to produce the same cr as the cs.
