Document Summary

Learning: involves the acquisition of new knowledge, skills, or responses from experience that results in a relatively permanent change in the state of the learner. Habituation: general process in which repeated or prolonged exposure to a stimulus results in a gradual reduction in responding. Sensitization: occurs when presentation of a stimulus leads to an increased response to a later stimulus. Classical conditioning: occurs when a neutral stimulus produces a response after being paired with a stimulus that naturally produces a response. Unconditioned stimulus (us) (food): something that reliably produces a naturally occurring reaction in an organism. Unconditioned response (ur) (salivation): a reflex reaction that is reliably produced by an unconditional stimulus. Conditioned stimulus (cs) (bell): a previously neutral stimulus that produces a reliable response in an organism after being paired with a us. Conditioned response (cr) (salivation): reaction that resembles an unconditioned response but is produced by a conditioned stimulus. Acquisition: phase when cs and us are presented together.
