Procedures For Measuring Behavior Flashcards
What devices are used to record event recording?
Wrist counters Hand-tally digital counters Abacus wrist or shoestring counters Masking tape Pennies, buttons, paper clips Pocket calculators
What is event recording?
Detecting and recording the number of times a behavior of interest occurs.
Each instance of behavior must have a discrete beginning and an end
What is timing?
Timing the duration of a behavior
Time latency and IRT
Activating a timing device when behavior starts and deactivate when it stops
What devices are used to record timing?
Stopwatches, digital wristwatches,bar code scanners, laptop computers handhelds
What is time sampling?
Methods for observing and recording behavior during intervals or at specific moments in time
When do you use time sampling?
When you can’t measure behavior continuously
The measures obtained from these samples are considered to be representative of behavior during entire time period observed
What are three types of time sampling?
Whole-interval recording
Partial-interval recording
Momentary Time sampling
What is whole interval recording?
Used most often to measure continuous behaviors or those that occur at such high rates that it is difficult to distinguish one response from the next. This method allows you to detect whether or not the behavior is occurring
What are parts of whole interval recording?
1-observation period is divided into a series of time intervals
2-depending on the behavior of interest and the length of te entire observation he intervals can be broken down into seconds or minutes 3- at the end of each interval observer records whether the behavior occurred throughout the entire interval
What is partial-interval recording?
1-observer records whether the behavior occurred at any time during the interval
2-not concerned with frequency of the behavior or the duration of he behavior 3-behavior occurs one time or lore than one time in an interval it is scored the same way 4- it often overestimates the actual occurrence
What is momentary time sampling?
Detects whether the target behavior is occurring at the moment that each time interval ends
-the observer looks up at the target person at the interval mark, determine immediately if behavior was occurring and record the data on the interval recording form
When are momentary time sampling used?
Observer doesn’t have to attend continuously
Used often for continuous activity behaviors that are easy to identify
Not used for low frequcney short durations behaviors
What is artifactual variability?
When something appears to exist due to the way it was measured to be examined
What does permanent product measure?
- measuring behavior after it occur by measuring the effects hat the behavior produced on he environment
- called an ex post facto method if data collection
What are examples of natural products?
Worksheets with completed math problems
Assembled box lunches
Soiled clothes
Wall painted
