Defining Target Behaviour Flashcards
-Operational Definition:
a description of variable in terms of operations used to establish or measure that variable
interobserver agreement / Interobserver Reliability
when two independent observers can view the definition of the behavior, view the behavior, and agree with the definition of the target behavior
Operational Definition characteristics:
- precise
- interobserver reliability: people using the same definitions should reach the same conclusions
- Quantitative
- Objective/unambiguous: not reference internal states, feelings, or motivations
- Practical
- important/Significant
category mistake
treating a category label as an instance of a category
- Example:
- Apple, Banana, peach (correct)
- Apple, banana, fruit (incorrect)
Measuring Target Behavior
-Behavioral Assessment:
baseline measurement of the target behavior
- Determine if treatment is necessary and helps you determine the best treatment
- Determine whether your treatment was successful
A-B-A-B Reversal Considerations:
- demonstrates a functional (causal) relationship between the manipulates variable and dependent variable and the dependent variable
- e.g. “Bobs aggressive behavior varies as a function of the teachers demands”
- i.e., “Demands cause aggressive behavior in Bob”
Direct vs Indirect Assessment
-Direct Assessment (ideal)
- target behavior is measured as it occurs
- the observer need not be a person, but can also be a camera or some other recording device
- self-monitoring: client is trained to observe their own target behavior. Useful when:
- independent observers are not available
- target behavior is infrequent
- target behavior does not occur in the presence of other people -
Indirect Assessment:
(tries to) measure behavior with interviews, questionnaires, and/or rating scales
- may rely on testimony from other people (parents, teachers, etc.)
- requires recall of an individual’s behavior (i.e. behavior is not measured directly)
- concerns:
- testimonials may be biased, inaccurate, unreliable, and/or incomplete

Research Designs
-Populations vs Individuals
-common statistical approaches emphasize average across individuals
-sample mean estimates the true population mean (
μ)
𝝁)
-sample variance: estimate the true pop variance (

)
Follow B.F. Skinner’s advice for internal validity:
-accurately describe the results at the level of each individual subject and then generalize (i.e. average) only when a repeatedly demonstrable truth emerges
-Single-Case Designs:
- within-subject research method concerned with discovering the principles and conditions that govern an individual organism. The individual acts as its own control group
- also called the Single-Subjects Design
- NOT the same thing as Case Study
-Accuracy
(error reduction / percent correction)
-Topography
form that behavior takes, (examining technique when playing an instrument)
-Intensity
increase resistance of the action (incorporate dynamics in music)
-Latency
the amount of time that has passed before a behavior occurs
