Document Summary

Behaviors that are reinforced (lead to satisfying consequences) will be strengthened, and behaviors that are punished (lead to unsatisfying consequences) will be weakened. Positive reinforcement: a pleasing stimulus is presented (e. g. praise for good work) Positive punishment: an unpleasing stimulus is presented (e. g. spanking) Negative reinforcement: an unpleasant stimulus is removed (e. g. aspiring eliminates headache) Negative punishment: a pleasing stimulus is removed (e. g. parents taking away candy from a child) Occurs when an animal (or human) is trained to make a particular response by reinforcing successively closer approximation to the desired response. Generally, reinforcement of positive behaviors are more effective. We process primitive features (color, shape, orientation, movement) at the same time, but only attend to one feature. Difficult to perform 2 tasks at the same time if they rely on the same sensory mechanisms. Even when involved in a conversation, in the midst of multiple conversations, at a cocktail party, hearing a particularly pertinent stimulus attracts your attention.
