Chapter 2- Methods In ABA Flashcards
Behavior assessment:
The attempt to (1)define the target behavior (2) identify fucking relations between the target behavior and its antecedents and its consequences; and (3) identify effective intervention for changing the target behavior.
Behavioral Assessment: steps #1Defining the target behavior:
Target behavior: the behavior to be changed by an intervention.
2 Identifying functional relations
You can do this by interviewing the client or others
Functional Analysis
The process of testy hypothesis about the function relations among antecedents, target behavior, and consequences.
-observation of the client (natural environment)
Identifying an intervention- recording data
Continuous recording and interval recording
Continuous recording
Recording each and every occurrence of a behavior during a prescribed period. E.g 30 mins
Interval recording
Recording whether a behavior occurs fudging each of a series of short intervals within an observation period… 10 seconds interval x 6 = 60 secs(Minute)
Measuring the Reliability of rate data:
You could use Inter-Observer reliability
Inter-Observer Reliability
A measure of the degree of agreement in data tallies made by two or more observers.
Reliability of Continuous Data
Smaller tally
————— X 100
larger tally
Reliability of Interval Data
Number of intervals
———————— X 100
Total # of intervals
Simple Frequency graph:
A graph in which each data point indicates the number of times a behavior occurred at a particular time.
Cumulative Frequency graph:
A graph in which each data point indicates the total number of times the behavior has occurred up to that point.
Single case experimental design
A research design in which the behavior of an individual is compared under experimental and control condition.
Baseline
A period during which the behavior study is recorded, but no attempt is made to modify it.
It provides a basis for comparison.
ABAB reversal design:
A single case design in which baseline and intervention conditions are repeated with the same person.
You essentially perform an experiment twice.
Multiple baseline design
A single case design in which the effects of an intervention are recorded across situations behaviors, or individual
Alternating treatment design:
A single case experimental design in which two or more interventions alternate systematically.
