Document Summary
Cat pull rope to get food) and "stamp out (random behaviour)" determine whether behaviours were maintained or eliminated. Law of effect: behaviours with positive consequences are stamped in, those with negative consequences are stamped out. Types of instrumental conditioning: behaviour changes through positive and negative reinforcers, presenting positive reinforcer increases behaviour, removing positive reinforcer decreases behavior, presenting negative reinforcer decreases behavior, removing negative reinforcer increases behaviour. Reward training presents positive reinforcer to encourage behaviour (ex. Omission training removes positive reinforcer to discourage behaviour (ex. Every time billy teases his sister while watching tv his mom will turn off the tv for 30 seconds) (ex. The timing of a reinforcer is critical to its effectiveness on a behaviour. The reinforcement works best when consequence immediately follows response: response rate measured visually through cumulative recorders, pattern of responding depends son subject complexity if behaviour and the of reinforcement used, autoshaping ex. Shaping used for behaviours too complex to be autoshaped.
