Document Summary
Chapter 7 stimulus control: discrimination and generalization. Antecedents: stimulus events that precede an operant response. The antecedents of a behaviour are the stimuli/events/situations/circumstances that are present when it occurs or were present immediately before the behaviour. Boy asks for money from mother, who gives it to him. Asks father for money, who does not give it to him. The boy ends up only asking his mother for money because he knows his father won"t give it to him. The first situation was reinforced while the second was not. Mother"s presence = antecedent for boy"s behaviour of asking for money = mother"s presence has stimulus control over boy. Stimulus control: a behaviour is more likely to occur when a specific antecedent stimulus is present. A behaviour is said to be under stimulus control when there is an increased probability that the behaviour will occur in the presence of a specific antecedent stimulus or a stimulus from a specific stimulus class.
