The Verbal Behavior Stimulus Control Ratio Equation: a Quantification of Language

Area of Science:

• Behavioral science
• Psycholinguistics
• Applied behavior analysis

Background:

• Language study has historically relied on structural analysis.
• B.F. Skinner proposed a functional analysis of verbal behavior within a science of behavior.
• Significant advancements have been made in explaining and predicting verbal behavior based on environmental variables over the last 60 years.

Purpose of the Study:

• To present a conceptualization of the interdependence of Skinner's verbal operants.
• To introduce a model for analyzing the complete verbal repertoire.
• To discuss implications for research and practice in verbal behavior analysis.

Main Methods:

• Introduction of the stimulus control ratio equation (SCoRE) as a metric.
• SCoRE summarizes a behavioral repertoire by comparing the relative frequencies of its components.
• The verbal behavior SCoRE compares observed response proportions against a null hypothesis.

Main Results:

• SCoRE provides a statistic to describe the current level of functional performance.
• This metric can be used to measure changes over time.
• It facilitates comparisons of treatment effects within individuals and across groups.

Conclusions:

• The stimulus control ratio equation (SCoRE) offers a novel way to quantify verbal behavior.
• Accurate description of the subject matter is crucial for advancing the science of behavior.
• This approach has potential applications in research and clinical practice for behavior analysis.
