Skinner Verbal BX
1) Systematic analysis of Language
Skinner Verbal Bx
2) Behavioral understanding of language through e.gs
-VB is Bx that is reinforced by the actions of another person
-Verbal Bx acts upon the social world (because it effects the bx of the listener)
• Skinner uses the same analysis & principles of bx that he applied to nonverbal bx
• Analyze the environmental conditions that control the bx: A-B-C
Views of Language
Biological
Views of language
-Cognitive
• receptive-expressive framework dominates the current language assessment & intervention programs for children w/ ASD
Views of Language
-Environmental
* both environmental variables & physiological processes
*Language perspectives
Skinnerian
-Functional Unit of analysis: -Operant -A-B-C -Bx of speaker

*Speaker & Listener
Speaker Someonewhoengagesinvbbyemitting mands, tacts, intraverbals, autoclitics, etc. A speaker is also someone who uses sign language, gestures, signals, written words, codes, pictures, or any form of vb.
Speaker and Listener
Listener: Someone who provides SR+ for vb. A listener may also serve as an audience evoking vb. The distinction between listener & speaker is often blurred by the fact that much of a listener’s behavior may involve becoming a speaker at the covert level (e.g., thinking about what was said). Often a speaker may be his own listener. (Sundberg, 2004)
“Receptive Language”
*Expressive Vs. “Receptive” Language!
Covert VB
*Verbal Operants
*All instances of vb can be classified into verbal operants
• Functional units of language A-B-C
• Units of language make up an individual’s verbal
repertoire
• Functionally independent of each other (different effects on environment)
• Each shares a common antecedent (SDs & MOs) & consequence
• Typical development: transfer across operants occurs rapidly & without direct teaching
• Those w/ ASD, transfer procedures are often required to teach verbal operants
Mand vs. Tact
Skinner wrote that the tact was the most important operant
Strong argument that mands are more important
*Mands:
-Response directly benefits the speaker
-Learn something about the condition (motivation) of the speaker
*Tacts:
-Response benefits the listener
-Learn something about the condition of the current environment
-Allows speaker to identify & describe features of his/her environment
Duplic Con’t:
Echoic, mimetic, copying a text
All have point to point correspondence & formal similarity
Mirrored responses
Imitation of words/sounds (echoic)
Imitation of Signs (mimetic)
Imitation of Picture Selection (mimetic)
Copying a text
*They all have a verbal response and a response with pt- pt correspondence and formal similarity & have generalized rein
Codic
*Has point-to-point correspondence with an antecedent verbal stimulus
*Does NOT have formal similarity Includes;
1. Textual (reading)
2. Diction (transcription)
3. Finger spelling words that are heard
Codic: Textual
Codic: Transcription
Point to point correspondence & no formal similarity
-Vocal Verbal STIM (Spoken words) -> Spelling/writing -> SR+ (RX)
Multiple Controlled Operants
*Responses can occur in multiple operants & can be controlled by one or more stimuli & one or more consequences
A: More than 1 STIM -> B: Verbal Res-> C: SR+
E.g. EO+presence of object (Object + verbal stimulus) -> More than one SR+
Multiple Controlled Operants
-Saying or Signing “Chocolate milk” in response to seeing a glass of chocolate milk & just having completed a hard physical workout mand/tact “What do you want?” where there is nothing of high value I sight could result in an Inter intraverbal-mand, if the child were to answer with a specific request.
Be aware of this when you are teaching!
Convergent multiple Control:
Divergent multiple control:
R1
R4 R2
R3
An single antecedent stimulus affects more than just one response
