PSYC 116 Chapter Notes - Chapter 5: Phenotypic Plasticity, Operant Conditioning Chamber, Latent Inhibition
Document Summary
Learning refers to a relatively permanent change in behavior as a result of experience. Phenotype: an observable characteristic of an organism. Phenotypic plasticity: an organism"s ability to produce different phenotypes as a result of different environments. All learning is a type of phenotypic plasticity, but not all phenotypic plasticity is a kind of learning. Simplest experience that can result in learning. Sensitization: becoming more sensitive to the stimulus over time. Habituation: becoming less likely to a stimulus over time. At times, experimenters need to go to great lengths to ensure that habituation does occur. Another example is animals that are rehabilitated in captivation and then released into the wild. Appetitive stimulus: any stimulus that is considered positive, rewarding, or pleasant. Aversive stimulus: any stimulus that is considered negative. Must do something whereas in classical, they do not have to do anything.
