Document Summary
Topography - the specific movements involved in a particular response, Need specific guidelines (e. g. , pictures, descriptions) to help record aspects of topography. Amount: frequency number of instances in a period of time (rate, duration how long a behaviour lasts. Relative duration: length of time a behaviour occurs within a specific period. Intensity force of a response (ex. speed), may use instruments to measure force. Stimulus control under which conditions does a behaviour occur. Latency amount of time between a stimulus and a response. Quality how well a behaviour is performed. Continuous recording recording every instance in a specific time period, only practical or feasible for certain types of behaviours. Sources of error: response definition: overly vague, characteristics of the observational situation make accurate observation challenging, poor training of observer(s, poorly designed recording materials (e. g. , data sheets) or procedures. Different calculation methods, 80% to 100% agreement generally considered acceptable. Direct behavioural assessment - other factors to consider with observation.
