Study Guide Flashcards
What is Frequency (count)?
Every time behavior occurs, you mark it
What is Rate?
Behavior occurs per time, useful if sessions vary in time
What is Duration?
Total extent of time in which a behavior occurs, must have obvious beginning and end
latency
How long it takes a child to follow an instruction (more generally, time from onset of stimulus to the initiation of a response)
What is inter-respone time (IRT)?
Time between two successive responses e.g. sips of juice, bites of food
Whole Interval
Did the behavior occur during the whole interval? Used to increase a behavior
Partial Interval
Did the behavior occur at all during interval? Used to decrease a behavior
Momentary time sampling
Measure behavior occurring at specific point in time, useful when observing multiple subjects at the same time
What is a Permanent product?
Measuring the effects of a behavior after it occurred. It leaves a permanent product. You can physically see it, like holes in the wall they punch the wall or a completed homework assignment
What do you do for Daily Data Collection?
Collect discrete trial data on a discrete trial data sheet and put data on a summary graph
What do you do for Monthly data collection?
Place data on data per month data sheet
Operational definition
Define a behavior in observable terms and as specific as possible. That way if two different therapists use your definition, they will measure the same amount of instances. You know you have a good definition if two people have a very similar amount of instances recorded while they measure independently, this is called interobserver agreement (IOA)
What are Preference assessments?
Are done to find objects and activities for which the learner has a higher preference. These shift over time and can vary by setting so preference assessments should be done regularly
What are Reinforcers?
Presented after a behavior which makes that behavior more likely in the future
Do preference assessments identify reinforcers?
No, they give you an idea of what can possibly work as a reinforcer but it is not considered a reinforcer until after it has been shown to make the behavior more likely
What are the 3 ways to do a preference assessment?
- Asking
- Free operant
- Trial Based
How do you ASK for a preference assessment?
Ask the person or significant others to name things they prefer or giving them a survey to rank in order of preference
What is FREE OPERANT for a preference assessment?
They are free to do whatever they want, you just observe and measure how much time a learner engages with an item and which times they engage with.
When is FREE OPERANT best to use?
- Good in situations where removing items causes problem behaviors
- If they are not able to communicate a preference when given a choice
- if you are assessing for reinforcers you cannot hold in your hand
What are the 2 ways to do FREE OPERANT?
- Naturalistic: where you let them roam free in their natural environment
- Contrived: Plant different items within view and easy access to learner and measure how much time they engage
What is TRIAL BASED for preference assessments?
Present stimuli in trials
What are Stimuli?
anything you can experience with your senses
What are the 3 different ways to present the stimuli in trials for a preferrence assessment?
- Single stimulus (successive choice)
- Paired Stimuli (forced choice)
- Multiple stimuli w/wo replacement
What is single stimulus?
One by one, good for when they have difficulty choosing between two or more objects and seeing if they approach or reject. You should present each stimulus multiple times and in a different order
What is paired stimuli?
2 at a time and having them choose. Each stimulus has to be presented with all other stimuli in the set and then you can rank in order of preference. This takes more time than single stimulus but is more accurate in finding higher preferred items
What is multiple stimuli with replacement?
Replaces unwanted items and keeps the same amount in the array
What is multiple stimuli without replacement?
You remove the chosen item, then rearrange the remaining items
What is a reinforcer assessment and when do you use it?
After the preference assessment and it takes the preferred stimuli and presents them after desired behavior to see how effective and strong a reinforcer is
What are Assessments?
The process gathering info. They can be used to determine preferences, assess skills in repertoire and to measure progress over time
What are RBT’s role during an assessment?
- The assist the BCBA or BCaBA with the assessment by helping collect data
- Conducting the assessment alongside their supervisor
- Trialing new tasks (probing)
- Communicating progress made during sessions to their supervisor
Do RBTs do assessments on their own?
No, this is the job of the BCBA or BCaBA on the case whose responsibility it is to choose the assessment tool, when to use it and conduct the bulk of the assessment
What are the 4 functions of behavior?
- attention/social positive
- tangible
- escape/avoidance
- automatic
What is Attention/social positive maintained by?
Maintained by attention of any type
What is Tangible maintained by?
Maintained by getting objects like toys or food. Think of things you can tangibly hold
What is Escape/avoidance maintained by?
Maintained by escaping or avoiding a situation
What does Automatic maintain?
Maintained by sensory. Automatic positive would be adding a pleasurable sensation. Automatic negative would be removing an aversive sensation
What are 3 types of functional behavior assessments?
- Indirect assessment
- Direct/descriptive assessment
- Functional/experimental analysis
What is an indirect assessment?
interviewing or giving questionnaires to individuals familiar with the learner
What is a direct/descriptive assessment?
observing behavior in the natural environment and not manipulating
What is a functional/experimental analysis?
manipulating environment by arranging antecedents and consequences to determine function
What should you do when you find out the function of the problem behavior?
Find a more acceptable alternative behavior which serves the same function as the problem behavior
What are the 4 essential components of a written skills acquisition plan?
- Choose skill to target (must be socially significant)
- Describe skill and what proficiency/mastery of skill looks like
- Choose data collection procedures (including what materials are needed, what type of prompts, how you will reinforcer and the plan for maintenance)
- Take baseline data (data before intervention is implemented with no consequences to see where they stand currently)
What is reinforcement?
an stimulus presented after a behavior that increases the likelihood of the behavior occurring in the future
When should you present the reinforcer?
Immediately after the behavior
