Belongingness – certain responses belong with certain reinforcers due to evolution Ex: Stickleback fish (Sevenster, 1973) I. cont. I. cont. 1. Instinctive Drift – operant response drifts from original to a more species typical (instinctive) response Behavior systems – operant response will match that of the activated system rats and ball bearings I. cont.

A. Instrumental Reinforcer 1. quantity and quality of reinforcer – can increase rate of responding or speed of responding (maze) 2. positive and negative contrast – responding is in part dictated by previous experience I. cont. I. cont.
Positive Contrast Prev. Reinforcer Current Responding Less attractive More attractive Increased Negative Contrast More attractive Less attractive Decreased Examples? I. cont. I. cont.
ResponseReinforcer Relation 1. Temporal contiguity – immediate reinforcement is better than delayed (Behavioral Economics) 2. Responsereinforcer contingency – if response results in reinforcer, response more likely to occur again (if positive reinforcement) A. I. Cont. I. Cont.
