IOA
What is the simplest method for recording IOA?
Total count IOA
Does partial interval recording overestimate or underestimate the occurrence of behavior?
Overestimate
Frequency
Count, number of times a behavior occurs.
Trials to Criterion
Ex. 12 correct trials to master handwashing, 3 days at 100% across 2 therapists.
If you are using the permanent product to measure behavior, the permanent product can only be produced by the target behavior.
True
Name 2 benefits of IOA
1. Determines the competence of new observers 2. Detects observer drift 3. Increases or decreases confidence that the definition of the target behavior was clear and the measurement code was not too difficult.
What is timing used to measure?
Duration, response latency, and inter-response time.
Response Latency
The time between onset of a stimulus and initiation of a response.
Magnitude
Force/intensity. Ex. volume of voice, pressure while writing.
If your client's target behavior results in a tangible product you should use event recording.
False.
What does reporting IOA increase?
Believability
Response latency, and interresponse time.
Inter-response Time
the measure of time that occurs between two consecutive instances of a response class.
Partial Interval Recording
Has the behavior occurred anytime during each interval.
For continuous behaviors, you should use a discontinuous measurement procedure.
True
Name 1 requisite for obtaining valid IOA.
1. Observers must use the same measurement system. 2. Observers must measure the same event. 3. Observers must be independent.
What are 3 indicators of trustworthy measurement
Accuracy, reliability and validity.
Observer Drift
When observers unknowingly alter the way they measure a behavior.
Temporal Locus
Measures the time at which a behavior occurs.
Ex. for eating behavior, you would record the time between each bite.
Do not use event recording when responses occur at very high rates.
True.
Name 1 method for calculating IOA for Event Recording and the formula associated with it.
Total Count: smaller#/larger# X100
Mean count per interval: Int1 IOA+Int2 IOA +IntN IOA/ total # of intervals.
Exact Count-per interval IOA: # of intervals of 100% agreement/total # of intervals X100
Trial by Trial IOA: # of trials of agreement/total # of trials X100
What are the three procedures for measuring behavior? Explain one.
Event Recording: number of times a response occurs.
Timing: used to measure duration, response latency and IRT.
Time Sampling: variety of methods for recording behavior during intervals or at specific moments in time.
Celeration
Count per unit of time/time. (frequency/time). A measure of how rates of response change over time.
Planned Activity Check
Ex. A teacher observes a group of students at the end of each interval and records the total number of students engaged in the target activity.
It is not recommended to use whole interval recording procedures when you want to increase behavior.
False.
