5025 Part 2 Flashcards
A B design
Baseline followed by treatment
Bar graph
Dependent variable represented on the Y axis. Phase or condition represented on the X axis
Behavioral assessment
Gather information to make data-based decisions on behavior-environment relations
Best fit line
Bisect data with an equal number of data points above and below the line
Changing criterion design
Treatment phase divided into sub phases which have different criteria that move closer to the goal
Component analysis
Systemic withdrawal of treatment components to determine if behavior change is maintained
Confound
An uncontrolled factor suspected of influencing DV
Data
Quantitative results of controlled observation
Data path
Series of straight lines connecting successive data points within a condition. Represents relationship between IV and DV
Data points
Value of DV at any point in time
Datum
Singular form of data
Descriptive assessment
Direct observation of Abc events under naturally occurring conditions
Dimensional quantities of response measures
Event, latency, duration and IRT
Dimensionless quantities of response measures
Percent, trials to criterion, discrete categorization, partial interval, whole interval, momentary time sampling, PLACHECK
Direct assessment methods
Measuring quantities of behavior, scatterplots and permanent products
Evocative effect
Momentary increase in the rate of behavior
Experimental design
Repeated, systematic presentation and removal of IV while measuring changes of DV
External validity
Extent to which results are generalizable to other subjects, settings and/or behaviors
Extraneous variables
Stimuli not related to the IV that may affect the DV
Functional analysis
Systematic manipulations of antecedents and consequences in a controlled setting to determine purpose of behavior
Functional assessment
Method to determine purpose of behavior
Graphic displays of ABA
Equal interval line graph, bar graph, semi-logarithmic graph, cumulative record
Indirect assessment methods
Record review, interviews and questionnaires
Internal validity
Extent to which analysis assures measured change in behavior is due to manipulated IVs
IOA criteria
80% agreement for 30% of observations
IOA methods
Total count or percent agreement
Level
Average value of data points across an entire condition or phase
Minimizes validity threats
Measurement, stability, immediacy, replication
Multielement design
Rapidly alternate between conditions
Multiple baseline design
IV introduced in a staggered order once behavior is stable for first baseline
Pairwise
One test condition alternated with control. Assists in discriminability of conditions
Parametric analysis
Examines the effects of a range of IV values
Partial interval recording
Occurrence is recorded if the response is observed during any part of the interval
Parts of an equal interval line graph
Title, legend, X axis, Y axis, data points, data path, phase change lines and labels
Phase change
Major change in the IV
Placheck
Percent of individuals engaged in target behavior immediately following an interval
Probes
Evaluate whether treatment affects are evident before treatment occurs
Procedural integrity
IV implemented as stated by the treatment plan
Progressive ratio schedule
Assess reinforcer effectiveness as response requirements increase
Response definition should be:
Clear, complete and objective
Sequential effects
Behavior in one condition influenced by experience in prior condition
Single-case design
Repeated presentation and removal of treatment while keeping other factors constant
Social validity
Treatment goals are useful for the individual and those around him
Threats to internal validity
History, maturation, testing, instrumentation, diffusion of treatment, regression towards the mean, selection bias, attrition
Trails to criterion
Number of consecutive responses required to achieve a performance standard
Trend
Overall direction of a set of data points
Type 1 error
Concluding the IV produced a change in the DV when it did not
Type 2 error
Concluding the IV did not produce a change in the DV when it did
Variability
Extent which measures of behavior diverge from one another
Visual analysis of a graph
Level, variability, trend, number of data points
Whole interval recording
Occurrence is recorded if the behavior is observed for the entire interval
Abative effect
Momentary decrease in the rate of behavior
