Experimental Design
A wide variety of research designs that use a form of experimental reasoning called baseline logic to demonstrate the effects of the IV on the behavior of individual subjects.
Single Subject Design
Measurement conducted in a manner such that all instances of the response class(es) of interest are detected during the observation period.
Continuous Measurement
Measurement conducted in a manner such that some instances of the response class(es) of interest may not be detected.
Discontinuous Measurement
Give the formula for TOTAL COUNT IOA
Smaller count/Larger count * 100
The variable in an experiment measured to determine if it changes as a result of the manipulations of the independent variable. In behavior analysis, it represents some measure of a socially significant behavior.
Dependent Variable
An experimental design consisting of an initial baseline phase, an initial intervention phase, a return to baseline condition, and a second intervention phase.
ABAB design, reversal design, withdrawl design
Simple tally of the number of responses observed.
Count
A measure of the total extent of time in which a behavior occurs.
Duration
Give the formula for TRIAL BY TRIAL IOA
number of trials (items) agreement/total number of trials (items) * 100
The variable that is systematically manipulated by the researcher in an experiment. In ABA, it is usually an environmental event of condition antecedent or consequent to the DV.
Independent Variable
An experimental design in which an initial baseline phase is followed by a series of treatment phases consisting of successive and gradually changing criteria for reinforcement or punishment.
Changing Criterion Design
A measure of the elapsed time between the onset of a stimulus and the initiation of the subsequent response.
Latency
In this time sampling method, the observer records wheather the target behavior occurred at any time during that interval. Tends to overestimate behavior.
Partial Interval Recording
Give the formula for TOTAL DURATION IOA
shorter duration/longer duration * 100
The overall direction taken by a data path.
Trend
An experimental design that begins with the concurrent measurement of two or more behaviors in a baseline condition, followed by the application of the treatment variable to one of the behaviors while baseline conditions remain in effect for the other behaviors. The treatment variable is applied in a sequential fashion.
Multiple Baseline Design
A ratio of count per observation time
Frequency/Rate
In this time sampling procedure, the observer records whether the target behavior occurred throughout the entire interval.
Whole Interval Recording
Give the formula for INTERVAL BY INTERVAL IOA
number of intervals agreed/number of intervals agreed + number of intervals disagreed *100
The value on the vertical axis around which a series of behavioral measures converge.
Level
An experimental design in which two or more conditions are presented in rapidly alternating succession independent of the level of responding
Alternating Treatment Design
A special form of event recording: a measure of the number of responses or practice opportunities needed for a person to achieve a preestablished level of accuracy or proficiency.
Trials-to-Criterion
The amount of time that elapses between two consecutive instances of a response class.
Interresponse Time (IRT)
Give the formula for EXACT COUNT-PER-INTERVALS IOA
Number of Intervals of 100% IOA/n intervals * 100
The frequency and extent to which multiple measures of behavior yield different outcomes.
Variability
