Document Summary
Classical conditioning classical conditioning neutral stimulus acquires the ability to signal the occurrence of a second, biologically significant event. Pavlov: conditioned presence of learning, unconditioned factors that are innate/unlearned, conditioned stimulus (cs)- env event whose significance is learned initially neutral event that takes on the ability to signal the occurrence of a. Repeated touching of the siphon reduced the size o excitatory postsynaptic potentials in both the interneurons and motor neurons. Postsynaptic mechanisms leading to structural change also contribute to classical conditioning. Reflexes, instinctive behaviors, and learning fall along a continuum of flexibility. Reflexes produce rigid patterns of response, whereas the flexibility of learned behaviors is well suited to rapidly changing environments. Major types of learning include habituation, sensitization, and classical conditioning. Research using aplysia suggests that learning results from both pre- and postsynaptic changes. Classical conditioning in vertebrates involves the amygdala (emotional learning) and the cerebellum (skeletal reflexes).
