Schools of Behaviorism

Methodological Behaviorism S-O-R Stimulus organism variable response Occurs in response to stimuli in the physical environment as mediated through presumed internal processes according to an S-O-R model of psychology.  Methodological behaviorists believe that human behavior results from the action of presumed organic variables that determines how a person responds to external stimuli. According to Methodological Behaviorism, talking is an overt […]

3 Ways to Measure Time

Latency:  The time from the presentation of a stimulus to the start of the behavior Duration:  The time from the start of a behavior to the completion of the behavior. Also called temporal extent. Inter Response Time: Time from the end of a response to the beginning of the next response

Interval Recording

Interval Recording

Time Sampling: Refers to a variety of methods to record behavior at specific moments.  One divides the observation period into intervals and then record either the presence or absence of a behavior within or at the end of the interval. Partial Interval Recording: Record whether the behavior happened at any time during the interval.  Tends to underestimate high-frequency behavior and […]

Standard Celeration Charts

Standard Celeration Charts

The standard celeration chart is a method of charting and analyzing changes over time.  Ogden Lindsely invented this charting technique in the 1960s.  The are 4 different types of charts which scale across the horizontal axis.  There is the daily (140 calendar days), weekly, monthly and yearly charts.  The daily chart is the one that is most often used in […]

Response-Deprivation Hypothesis

Response-Deprivation Hypothesis

The term “response-deprivation hypothesis” refers to a model for predicting whether or not one behavior will function as a reinforcement for another behavior. Restricting access to the one behavior would create a state of deprivation for access to that behavior which creates a situation where access to the deprived behavior acts as a potential reinforcer if the baseline data indicates […]

Matching-to-Sample and Stimulus Equivalence

Matching-to-Sample and Stimulus Equivalence

Matching to Sample in ABA refers to a procedure where a stimulus is presented and taught to match a secondary stimulus (such as the word “car” and a picture of a car).  When the two stimulus are correctly matched, a reinforcer is given to increase future likelihood  of the stimulus matching to occur again. Reflexive is also called identity matching.  […]
