Behavior Analysis
| Question | Answer |
|---|---|
| Come up with a behavioral definition | Example: The girl bites her nail |
| Make a definition more interpretive | This involves making it more vague and using words like anxiety, overthinking, satisfied, etc. Example: The dog was satisfied |
| Accuracy vs. Validity | Accuracy: Ensures the measurement reflects exactly what happened and the recorded data matches the true value of the behavior... Validity: Ensures the measuring tool is measuring the intended behavior that matches your "why" and not irrelevant behavior. |
| Definition of a unit | What counts as one for your behvaior measurement |
| Reliability vs. Reproducibility | Reliability: Consistency of measurement system across observers/ over time. Reproductibility: The ability to conduct the same experiment and get the same consistent results even with different observers. |
| Frist two Approaches/Models for defining behavior | Movement: Behavior that involves observable movement and is not permanent Product: Behavior that leaves a product in the environment permanently or partially permanently that can be seen and observed |
| Second two Approaches/Models for defining behavior | Specific Response: an observable, measurable action by an individual representing their reaction to an environment. General Category: a systematic teaching strategy designed to ensure that skills learned in therapy can be applied in other situations. |
| What is a dimension of behavior? | A quantifiable property or characteristic of behavior that can be measured. |
| Describe how dimensions are specified either by creating units or by the way units are measured. | Frequency (how often a behv. occurs), duration (how long behv. occurs), latency (how much time elapses after stimulus before behv. occurs), magnitude (how intense behv. is), and IRT (time between each successive response). |
| Threats to Measurement Reliability | Poorly defined operational systems (vague or interpretable), complex measurement systems (too many behv.s & fast paced data collection is likely to lead to inaccurate data), and observer drift (observers changing how they apply definitions over time). |
| Threats to Measurement Validity | Wrong dimension of behavior being measured (using frequency why your "why" is asking about speed), using indirect measurement units (reports rather than direct observation), and poorly defined behavioral definition (poor definition = inaccurate data) |
| Threats to Measurement Accuracy | Incorrect measure instruments (using the wrong kind of timer), improper use of measurement procedures (using partial-interval when continuous measurement is required = inflate data), and measurement bias (lying about data to meet goal) |
| What are these recording methods: CR, PI, WI, MTS? | continuous recording, partial-interval recording, whole-interval recording, and momentary time sampling. |
| When would you use occurrence (scored), nonoccurrence (unscored), and interval-by-interval IOA? | Occurrence 9scored) when you have little behavior data, when you have a lot of data use nonoccurrence (unscored), and use interval-by-interval when you have a moderate rate of behavior occurring. |
| Why do we graph data in ABA? | To see if there's a relationship between our data, have a clear representation of the distribution, see trends, determine validity, and gather more intel that tells us more overall than our measurements can. |
| I am measuring cumulative duration throughout a session. Due to logistical constraints, I cannot measure the duration of each response. What IOA should I use and why? | Since you are adding up the total time the behavior lasts in each response (cumulative duration) but you cannot split it into intervals due to logistical constraints it would be best to use total IOA because it's the only non-interval IOA |
| Is it a good idea to exclusively use indirect measures like surveys to measure or assess behavior? WHy or why not? | No, because they don't always provide descriptive or sufficient data plus people taking surveys aren't always truthful. |
| What is the advantage of having an offset and onset in your behavioral definition? | You know when your behavior starts and stops, you know what to count as an instance of behavior, it makes measurement more clear, and it helps you know when a new behavior takes place. |
| Describe and be able to differentiate observable/non-observable | Observable behaviors are visible to see and measure, they can be counted. Non-observable behaviors are difficult to define and can be covert like thinking, imagining, etc. We want to make sure our behaviors are observable and measureable (not implicit). |
| Describe and be able to differentiate descriptive/ interpretive | A descriptive approach is observable, objective, and focuses on measureable facts while an interpretive approach focuses on underlying meanings, is subjective, and can have different meanings based on opinion, which can vary person to person. |
| Name examples of historically common explanations for behavior that don't actually explain behavior. Why do they not actually account for behavior? | Astrology, Demonology, Phreneology, etc. She procrastinates because she's a procrastinator. He's aggressive because he has an aggressive behavior. Circular explanations with no true explanation why the behavior occurs. |
