Measurement Flashcards
Data
information that is gathered that will help you to make informed decisions about your client’s progress.
Who is primarily responsible for making treatment decisions?
The behavior analyst (Supervisor)
What does data collection using continuous measurement look like?
Continuous measurement requires the person taking the data to keep their eyes on their client the entire time, so they never miss the behavior happening a single time.
Ways to Take Continuous Data:
1) Frequency
2) Duration
3) Latency
4) Inter Rate Response (IRT)
What is frequency measurement procedure?
Counting how often a behavior occurs. We use frequency when the behavior we’re tracking looks the same every time.
How is rate used in data collection?
When you measure how often a behavior occurs over a specific period of time.
What is duration measurement procedure?
How long a behavior occurred in a specified period of time. Measures from the start of the behavior until the end of the behavior.
What is latency measurement procedure?
How long it takes for a behavior to begin after an instruction is given. Measures from the time the instruction is given until the client begins to follow that instruction.
What is IRT measurement procedure?
The time between responses.
What does data collection using discontinuous measurement look like?
With discontinuous measurement, data is taken on only a sampling of the behavior. Although this means the data is less accurate than continuous measurement, it is easier to collect.
Three Ways to Take Discontinuous Data
1) Whole Interval Recording
2) Partial Interval Recording
3) Momentary Time Sampling
What is partial interval recording?
Recording a behavior as happening if it occurs at any point during the interval (period of time).
While using partial interval recording, if the behavior happens for only a few seconds during an interval, would you still mark the behavior as occurring?
YES - you would, because it did occur even though it was for a tiny bit. Therefore, partial interval recording is considered an overestimate, or exaggeration of a behavior’s occurrence and we use it to track behaviors we want to see decrease, such as the self-stimulatory behavior of eye gazing.
What is whole interval recording?
Recording a behavior as happening only when it occurs the entire interval (period of time).
What is momentary time sampling ?
Recording if a behavior is happening at a predetermined precise moment in time. Usually at the end of an interval.
What is permanent product recording?
Recording the tangible/environmental effects of a behavior after it occurs.
Line graph
A line graph is commonly used to display data in ABA. Line graphs allow you to observe small changes and patterns in your data so you can make informed decisions on whether or not treatment is working and should therefore continue.
Disruptive behavior
A behavior you would want to decrease.
What type of data collection procedure is Frequency?
Frequency is a continuous measurement procedure
What is behavior?
Anything a person (client) says or does, their words and actions.
What is environment?
The surroundings in which we live. This includes everything except the words & actions of the person (client) you’re observing.
What is an operational definition of a behavior?
Describing what a behavior looks/sounds like in an observable and measurable way using clear, concise, complete and objective terms.
Why do we need an operational definition for a behavior?
So everyone working with a client is clear which precise behavior they are looking for and collecting data on.
Operational Definition Components:
1) Label
2) Definition (observable & measurable)
3) Example
4) Non-Example
What is one disadvantage of using Whole Interval Recording?
Underestimation of the occurrence of the target behavior
Observable behaviors are those that can be:
Witnessed and recorded by an observer
