PSYB45H3 Lecture Notes - Lecture 9: Dependent And Independent Variables, Functional Analysis
Document Summary
An antecedent stimulus or event that alters the value of a reinforcer/punisher and alters the probability of the behaviour that produces that reinforcer/punisher. Four phases of behaviour modification programs: screen or intake: Which behaviour to focus on: baseline: Determine the level of target behaviour prior to treatment intervention. Different assessment procedures for collective baseline information: Interviews, questionnaires, numerous types (behavioural checklists), role-playing, information from other professionals, client self-monitoring. Example of a general psychiatric intake interview with a client experiencing anxiety. Accuracy - more accurate than indirect assessment. Examine factors that control and maintain problem behaviour. Collection of accurate behavioural data can be very important for numerous reasons: Reactivity: simply tracking/ recording behaviour can lead to behaviour change. The specific movements involved in a particular response. Need specific guidelines (e. g. pictures, descriptions) to help record aspects of topography. Frequency: number of instances in a period of time (i. e. rate) Relative duration: length of time a behaviour occurs within a specific period.
