Stimulus equivalence is a concept in Applied Behavior Analysis (ABA) that explains how relations can be formed among stimuli.
What is stimulus equivalence in psychology?
stimulus equivalence. the condition in which two or more related stimuli elicit the same response. Stimuli meet the mathematical definition of equivalence if they can be shown to exhibit reflexivity, symmetry, and transitivity. Click to see full answer.
What is an equivalence class in ABA?
Also know, what is an equivalence class ABA? EQUIVALENCE CLASS : A stimulus class (usually produced through conditional discrimination in matching-to-sample) that includes all possible emergent relations among its members. The properties of an equivalence class are derived from the logical relations of reflexivity, symmetry, and transitivity.
Is the AB test a sufficient test for stimulus equivalence?
It is considered to be a sufficient test for stimulus equivalence because it simultaneously evaluates both symmetry and transitivity (reflexivity is assumed). Specifically, the combination of the AB and BC relations yields the AC relation via transitivity, and its symmetrical counterpart is the CA relation (but see Pilgram & Galizio, 1995 ).
What is the difference between ABA and stimulus control?
Both ABA and stimulus control are based on principles of operant conditioning, a form of psychology that uses rewards to help individuals change their behavior. As such, it makes sense that a part of ABA would revolve around stimulus control. How Do ABA Therapists Use Stimulus Control?
What is stimulus equivalence examples?
For example, if a child has learned to be cry in the presence of dogs, this may transfer to crying when seeing a cat as well because they are both fluffy animals in the same stimulus class.
What is equivalence in ABA?
Stimulus equivalence is a concept in Applied Behavior Analysis (ABA) that explains how relations can be formed among stimuli.
What is stimulus stimulus relations ABA?
Target Term: Derived Stimulus Relations. Derived Stimulus Relations. Definition: A relation between two or more stimuli that is not directly trained and not based on physical properties of the stimuli.
What are the three components of stimulus equivalence?
#Stimulus equivalence classes are formally defined by reflexivity, symmetry, and transitivity between stimulus class members. all three are EMERGENT behaviours.

Why is it important to teach a child stimulus equivalence?
Of particular importance was the fact that both children learned to read words as a by-product of the instruction. Thus, stimulus equivalence appears to be a promising technique for teaching beginning reading skills and may serve as a model for teaching reading and other verbal behavior skills.
What is an advantage of stimulus equivalence training?
What is an advantage of stimulus equivalence training? They can control behavior without being linked to reinforcement.
Is derived stimulus relations the same as stimulus equivalence?
Equivalence involves correctly responding to stimulus-stimulus relations that have not been trained or reinforced but are the result of reinforcing other stimulus-stimulus relations (Cooper, Heron, and Heward, 2007). Derived stimulus relations are basically new connections that learners make.
What are the properties of stimulus equivalence?
Sidman's conceptualization of stimulus equivalence defines it in terms of the mathematical relations of reflexivity, symmetry, and transitivity. To fulfill this definition, an equivalence relation has to posses all three of these properties.
How is stimulus equivalence different from RFT?
1) Stimulus equivalence is an empirical phenomenon; RFT is a behavioral theory about how that phenomenon (and other phenomena) comes about. In other words, RFT provides an operant analysis of how/why people are able to form equivalence classes.
What is stimulus equivalence?
stimulus equivalence. the condition in which two or more related stimuli elicit the same response. Stimuli meet the mathematical definition of equivalence if they can be shown to exhibit reflexivity, symmetry, and transitivity.
What are ABA techniques?
A brief overview of some teaching techniques, based on the principles of applied behavior analysis (ABA). Active Student Responding, Activity Schedules, Discrete Trial teaching, TAGteach, Task Analysis, Video Modeling, Visual Schedules,and more as well as some comments on Prompts and Reinforcement.
What is an arbitrary stimulus class?
Arbitrary Stimulus Class. A set of stimuli that evoke the same response, but do not share a common stimulus feature. They are stimulus from the same category but cannot be defined by a shape like in feature stimulus class.
How do you explain a stimulus control?
Stimulus control is a term used to describe situations in which a behavior is triggered by the presence or absence of some stimulus. If a person always eats when watching TV, then (in the operant conditioning use of the term) eating behavior is controlled by the stimulus of watching TV.
What is a controlled stimulus?
In classical conditioning, the conditioned stimulus is a previously neutral stimulus that, after becoming associated with the unconditioned stimulus, eventually comes to trigger a conditioned response.
What are the characteristics of stimulus?
In physiology, a stimulus (plural stimuli or stimuluses) is a detectable change in the physical or chemical structure of an organism's internal or external environment. The ability of an organism or organ to respond to external stimuli is called sensitivity.
What is an example of a discriminative stimulus?
In the example above, the grandma is the discriminative stimulus for the behavior of asking for candy.
When is stimulus equivalence achieved?
Stimulus Equivalence has been achieved when ALL reflexive, symmetrical and transitive matching has been learned.
What is matching to sample in ABA?
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.
What is arbitrary stimulus?
In an Arbitrary Stimulus class, the stimuli do not look alike but the share the same response. For example, “3+3”, “half a dozen” and “number of kids in the Brady Bunch ” all equal 6!
When teaching a behavior in the presence of a stimulus that is a member of a stimulus class, should?
Teaching a behavior in the presence of a stimulus that is a member of a stimulus class should generalize over to the other members in the stimulus class. When adding a new item to a stimulus equivalence class, the new item must be conditioned to at least one stimulus in the equivalence class.
When a learner can match two stimuli that are equivalent due to a relationship with a third stimulus,?
When a learner can match two stimuli that are equivalent due to a relationship with a third stimulus, this is called transitivity.
What is transitive in math?
Transitive this occurs when the equation if A = B and if B = C, then A = C. In other words one stimulus is matched to a second stimulus. The second stimulus is matched to the third stimulus. By this relationship, the subject learns that the first stimulus and third stimulus are also matching. For example, if you say “bird” and show a child a picture of a bird, then you show a picture of a bird and match it to a real bird in a cage, the relationship of saying bird for the caged animal is acquired.
What is stimulus equivalence?
Stimulus equivalence, as studied by behavior analysts, is a relatively new research area that has been rapidly expanding. Many behavior analysts are excited about the topic, and its possible far reaching implications have not gone unnoticed ( Sidman, 1994 ). The research itself focuses on relations among stimuli.
Why are behavior analysts excited about the stimulus equivalence?
Why are behavior analysts excited about the stimulus equivalence? First, it seems clear that people know more than they have been directly taught. Stimulus equivalence research is discovering specific learning histories that can account for this fact (see also Alessi, 1987 ). The research is showing that a little bit of training goes a long way. In our example, Laura was only taught only two relations (AB and AC); consequently, she also proved capable of performing in accordance with seven others (AA, BB, CC, BA, CB, AC, CA). And consider this. Suppose we teach Laura only one more relation. Perhaps we show her a picture of a cat, along with the Spanish words from Set C as comparisons, and reinforce her for selecting the gato card (DC). She will then likely prove capable of six more untrained performances: DD, AD, DA, BD, DB, CD (e.g., Sidman & Tailby, 1982 ).
What is the standard stimulus equivalence paradigm?
In the standard stimulus equivalence paradigm, relations among stimuli are determined by the choices of a learner. Specifically, the learner is shown a sample stimulus together with some other stimuli that are to be compared to the sample.
What is the key contribution of stimulus equivalence research?
Sidman (1986) summarizes what may be the key contribution of stimulus equivalence research: "By reacting to a word as an equivalent stimulus - the meaning of a word - a person can behave adaptively in an environment without having previously been exposed to it.
What is the arrow in the top panel of the equivalence test?
The arrow shows the derived transitive relation (AC); the dashed line indicates that the relation is untrained. The bottom panel shows the procedure involved in the equivalence test for the same two trained relations. The dashed arrow shows the derived untrained relation (CA) whose emergence would be indicative of equivalence among A, B, and C stimuli. Other details as in Figure 1.
What are the properties of a stimulus?
Reflexive properties involve the relation between a stimulus and itself (e.g., A = A). Symmetrical properties involve the relation between a pair of ordered stimuli, such that their order is reversible (e.g., if A = B, then B = A). Transitive properties involve two ordered pairs of stimuli, such that the second element of the first pair is the first element of the second pair, which in turn determines a third ordered pair (e.g., if A = B and B = C, then A = C). When stimuli have these relations to each other, they are said to form an equivalence class.
