PSYB45H3 Chapter 21: Chapter 21
Document Summary
Chapter 21: direct behavioural assessment what to record and how. 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) Duration: how long a behaviour lasts, relative duration: length of time a behaviour occurs within a specific period. The force of a response (e. g. , volume, speed: may use instruments to measure force. Amount of tie between a stimulus and the response. A refinement of one or more of the other characteristics (e. g. , shorter latency, stronger intensity, lower frequency) Continuous recording: recording every instance in a specified time period, only practical or feasible for certain types of behaviours. Yes or no: partial-interval recording: target behaviour is recorded a maximum of once per interval, whole-interval recording: target behaviour is only recorded if it occurs throughout the entire interval.
