PS261 Lecture Notes - Lecture 3: Classical Conditioning, Drug Tolerance, Habituation
Document Summary
Elicited behaviours can be modified by habituation and sensitization. Dual process theory: habituation process happens on the s-r system stimulus specific, less neurotransmitter released into the synapse, sensitization process happens in the state system not stimulus specific, more neurotransmitters is released. Opponent process theory: homeostasis, primary process opponent process. Chapter 3 part 1: foundations of classical conditioning. Ivan pavlov russian physiologist: history of classical conditioning, serendipity, psychic secretions, association, orosensory stimuli, object learning. Conditional stimulus is paired with unconditional stimulus. They have to be paired in order for this to work. Watson conditioning emotional responses: behaviourism. Thompson lowered tiny electrodes into different parts of the brain: neural activity in hippocampus, responsible circuit is in the cerebellum. Give rats radiation (makes them sick) after saccharin water. Chapter 3 part 2: excitatory and inhibitory pavlovian conditioning. Classical conditioning ivan pavlov history of classical conditioning. Mechanism unconditional stimulus, conditional stimulus, unconditional response, Food conditioning taste aversions and taste- preferences.
