Document Summary
Psyc*2330 lecture 16 week 8 - negative reinforcement and punishment. Negative reinforcement is not intrinsic in the stimulus. If you talk about positive reinforcement as giving candy you have a problem explaining negative reinforcement, would it be bad candy? no. Negative reinforcement = removal of an aversive. Avoidant response - as soon as the tone comes on the rat jumps to the other side and avoids it all together. Escape is when they experience shock and run away from the shock. If they avoid the shock all together it s avoidance. It s a paradox because it keeps happening and you don t know why it keeps happening. The biological stimulus is not presented but the behaviour continuers. Paradox is the animal keeps jumping after the us is removed. Take away the us and behaviour increases = negative reinforcement. Avoidance response ----> termination of tone (cs) = reduction of fear (cr)
