Exam Review- April 4, 2013 April 4, 2013 6:07 PM  Assumption of behavioural modification o Behaviours are learned o Behaviours are flexible and can be changed  Adaptive behaviours can be learned/ strengthened  Maladaptive behaviours can be weakened/ distinguished o Behaviour occurs, and can be observed, within a specific context  Preceding event, behaviour and subsequent result  Aka antecedent, behaviour, consequence, A-B-C  Assessment procedure o Define the target behaviour in precise behavioural terms  Definition must be objective  It is important to separate the behaviour from  Products of behaviour  Labels o Determine the baseline  Monitor the behaviour  Topography  Frequency/ rate  Duration  Intensity  Latency o Functional analysis  In addition to observing , antecedents and consequences are systematically changed so that the influence on the behaviour can be observed  Helps to discover controlling variables o Identify current stimulus control (stimuli that either deter or increase the behaviour)  What stimuli are present when the behaviour occurs?  What stimuli are present when the behaviour fails to occur? o Antecedent  A stimuli that precedes (comes before) the behaviour  Controlling stimulus D  Discriminative stimulus (S )  Stimulus delta ( )  Rules  Goals  Modelling  Motivation  Behavioural treatment o How can you use antecedent control?  Rules  Goals  Modelling  Physical guidance  Situation inducement  Motivating operations o Positive reinforcement= reward  If you're developing a new behaviour  Fading  Reinforcing the same behaviour across different stimuli contexts through successive trials  Shaping  Reinforcing closer and closer approximations of the desired behaviour  Chaining  Reinforcing a sequence of behaviours, usually in a successive sequence o Negative reinforcement= removing aversive o Positive punishment= aversive stimuli o Negative punishment= removing reward  Schedules of reinforcement o Continuous reinforcement o Intermittent reinforcement  Ratio  The behaviour is reinforced based on the number of times that it occurs  Interval  The first instance of the behaviour is rewarded after a period of time (interval) where no rewards are given  Duration  The behaviour is reinforced after it has occurred for a period of time o Intermittent schedules  All 3 schedules (ratio, interval, and duration) can be either:  Fixed  Fixed ratio  Fixed interval  Fixed duration  Variable  Variable ratio  Variable interval  Variable duration Schedule What is reinforced? Ratio A number of behaviours  Fixed  Every set # of behaviours
