Continuous Measurement
Number of times a behavior occurs.
Frequency
What type of discontinuous measurement would you use if you are recording behavior that occurs during the ENTIRE interval?
Whole Interval Recording
Where is the X-axis located on a graph?
Horizontal line (e.g., day, month, session, year, week)
What type of preference assessment is this? This assessment records the amount of time a client engages in a particular activity/reinforcer, then compares it to the amount of time engaged in other activities/reinforcers.
Free operant preference assessment
Which type of continuous measurement would you use to record how long a behavior lasts?
Duration
This type of discontinuous measurement is used when observations only occur for a subset of an interval. Only a part of the entire interval is observed.
Momentary Time Sampling
Where is the Y-axis located on a graph?
Vertical line (e.g., duration, rate, frequency, percentage)
What type of preference assessment is this? This assessment allows a teacher/therapist to create a hierarchy of the child’s preferences where the teacher presents two items in each trial and asks the child to make a choice based on those two items. Whichever item the child chooses, will go on the hierarchy of preferences.
Paired stimulus preference assessment (“forced-choice”)
Measuring how long it takes for a behavior to begin after a specific demand or event has occurred is..
Latency
What type of discontinuous measurement would you use if you are recording whether the behavior happened at any time during the interval?
Partial Interval Recording
What is the independent variable?
The independent variable is the variable that is MANIPULATED by the experimenter (the cause/what you are studying)
What should you do first before initiating a preference assessment with a client?
Ask the individual, caregivers, parents, teachers, or friends about the person’s preferences. This can be done by asking open-ended questions.
The time between the end of one response and the beginning of another response is..
Inter-Response Time (IRT)
Nate is recording Gia’s slapping behavior. He is using a 25 second time interval. Whenever Gia slaps during that interval, he will record the behavior as occurring once in the time interval no matter how many times she actually engaged in the slapping behavior. Which time sampling procedure is he using?
Partial Interval Recording
What is the dependent variable?
The dependent variable is the variable that is MEASURED by the experimenter (it depends on the independent variable).
What type of preference assessment is this? The stimuli chosen by the learner does not go back into the array. Instead, we will have a gradually decreasing array until all items have been chosen. With this method, a hierarchy of preference can be identified.
Multiple stimulus without replacement (MSWO)
What is the difference between rate and frequency?
Both frequency and rate measure the number of times a behavior occurs, but rate is time based and frequency is not. Rate is more accurate and frequency is easier to calculate.
During your session you are taking data on hand flapping. You only mark down that the behavior has occurred if it occurs for the entire five second interval. In this example, which time sampling method are you using?
Whole Interval Recording
What are the independent and dependent variables in this scenario? The amount of water affects the size of the plant.
Independent variable: The amount of water
Dependent variable: The size of the plant
What type of preference assessment is this? With this option, the learner chooses a stimulus, and that stimulus goes back into the array, but the unchosen stimuli are removed and replaced by new stimuli.
