Document Summary
Psych 261 textbook chapter 13. 1 and 13. 2 reading summary. Learning to automatically make a particular response in the presence of a particular stimulus; includes classical and instrumental conditioning. Hebb rule: the hypothesis proposed by donald hebb that the cellular basis of learning involves strengthening of a synapse that is repeatedly active when the postsynaptic neuron fires. Instrumental conditioning: a learning procedure whereby the effects of a particular behavior in a particular situation increase (reinforce) or decrease (punish) the probability of the behavior; also called operant conditioning. Reinforcing stimulus: an appetitive stimulus that follows a particular behavior and thus makes the behavior become more frequent. Punishing stimulus: an aversive stimulus that follows a particular behavior and thus makes the behavior become less frequent. Long-term potentiation (ltp: a long-term increase in the excitability of a neuron to a particular synaptic input caused by repeated high-frequency activity of that input.
