PSYC 616 Lecture Notes - Stopwatch, Tantrum, Psy
Document Summary
Used to determine the total amount of time engaged in a behavior during an observation session. Determine the observation session length (e. g. , 5, 10, 15, 30, 60 minutes, etc. ) and set a timer for that length. At the end of the observation period, the number on the stopwatch is the total duration. Converting total duration to percentage of time. Converting to the percentage of session time engaged in behavior is useful when observation session lengths vary. Total duration x 100 = % of session time engaged in behavior. 30 min of tantrums x 100 = 50% of session tie engaged in behavior. 30 minutes of tantrums during a 60-minute observation (50% of session time) Is not the same as 30 minutes of tantrums during a 30- minute observation (100% of session time) They appear equal if only looking at minutes (30 minutes)
