Invited Tutorial #120
SQAB Tutorial: Stimulus Equivalence 101
Saturday, May 25, 2019
4:00 PM–4:50 PM
Swissôtel, Concourse Level, Zurich D
Area: SCI; Domain: Basic Research
PSY/BACB/QABA/NASP CE Offered. CE Instructor: Caio Miguel, Ph.D.
Chair: Anna I. Petursdottir (Texas Christian University)
Presenting Authors: : CAIO MIGUEL (California State University, Sacramento)

Researchers and clinicians rely heavily on the matching-to-sample procedure (MTS) to establish conditional discriminations. In an MTS trial, a visual or auditory sample is presented, followed by several comparisons (pictures or objects). The selection of the correct comparison leads to reinforcement while selection of the incorrect one leads to some form of correction. Clinically, MTS is used for teaching a variety of skills, including listener behavior, categorization, math, and reading. An important characteristic of MTS is that samples and comparisons become substitutable for each other (i.e., equivalent). Understanding the variables responsible for the development of equivalence classes has been the topic of investigation in the field of behavior analysis for almost 50 years, generating an enormous (and complicated) body of research. This research has led to the development of at least three theoretical accounts to explain meaning and symbolic behavior, as well as has informed clinicians on how to take advantage of the MTS procedure to produce a multitude of generative/novel performances. This talk will serve as a first introduction to the concept of stimulus equivalence and its ramifications for both research and practice.

Instruction Level: Basic
Target Audience:

Basic researchers, students, board certified behavior analysts, and licensed psychologists.

Learning Objectives: At the conclusion of the presentation, participants will be able to: (1) describe the different parameters that affect equivalence outcomes; (2) describe the three main theories explaining equivalence outcomes; (3) understand the theoretical and applied implications of equivalence research.
