Competency Assesment Flashcards
Frequency
Count of each instance
Duration
Time spent engaged in a single instance of target behavior
Latency
Time from onset of stimulus to onset of response
Continuous measurement
Frequency, duration, latency and IRT
Discontinuous measurement procedures
Momentarily time sampling, partial interval recording and whole interval recording
Momentary time sampling
Recording occurrence/non-occurrence at specific point in time (end of interval)
Partial interval recording
Recording if the target behavior occurred at any point in time in a predetermined interval
Whole interval recording
Recording if the target behavior occurred for the entire duration of a predetermined interval
Permanent product recording
Recording behavior based on a finished product or tangible outcome
IRT
Time in between two responses
What is the difrence between continuous measurement and discontinuous measurement 
With Continuous measurement you take data on Continuously throughout the observation period with discontinuous you take data for a sample of the observation period
How do you average a graph
Add up the data for behavior and divide by amount of time
What is your role in preference assessments
To assist you, they should be practiced constantly, always looking for reinforcers
Types of preference assessment
Single stimulus
Forced choice
Multiple stimulus with out replacement
Single stimulus
Present an item and gage the reaction
Forced choice
Present items and ask them to choose then record what is chosen. Each item has to be presented with one another twice, the second time switching sides in case of side bias
(Time selected)/(total times presented) x100 = percentage of opportunity
Multiple stimulus without replacement
Present array of items and ask to select one, represent items without selected items arranged difrently and repeat until one left
