Control by compound antecedent stimuli in verbal behavior represents an understudied but promising area of research. To date, reference to compound verbal stimulus control has generally only included descriptions of convergent multiple control. A sizeable experimental literature exists on the topic of compound stimulus control, which differs from…

Autoclitics are secondary verbal operants that are controlled by a feature of the conditions that occasion or evoke a primary verbal operant such as a tact or mand. Qualifying autoclitics extend, negate, or assert a speaker's primary verbal response and modify the intensity or direction of the listener's behavior. Howard and Rice (1988)…

Children with autism spectrum disorder (ASD) may have difficulty acquiring intraverbal behavior. The present study compared manipulations of stimulus salience (i.e., volume increase, elongation) to teach intraverbals (e.g., "You drink [juice]" and "You drink from [cup]") to three participants diagnosed with ASD whose…

Since speech is a continuous stream with no systematic boundaries between words, how do pre-verbal infants manage to discover words? A proposed solution is that they might use the transitional probability between adjacent syllables, which drops at word boundaries. Here, we tested the limits of this mechanism by increasing the size of the word-unit…

Background: The comprehension profile of people with agrammatism is a debated topic. Syntactic complexity and cognitive resources, in particular phonological short-term memory (pSTM), are considered as crucial components by different interpretative accounts. Aim: To investigate the interaction of syntactic complexity and of pSTM in sentence…

Conceptually, the use of the technical term "naming" appears to be a broad term that describes several subtypes of emergent verbal behavior. Miguel ("The Analysis of Verbal Behavior," 32, 125-138, Miguel, 2016) introduces the concept of subtypes of naming, specifically common bidirectional naming and intraverbal bidirectional…

Convergent intraverbals represent a specific type of intraverbal in which multiple components of one speaker's verbal behavior control a specific verbal response from another speaker (e.g., Speaker 1: What wooly, horned animal lives in the high country? Speaker 2: Bighorn sheep). To foster the development of advanced language, Sundberg and…

The importance of the intraverbal relation is missed in most theories of language. Skinner (1957) attributes this to traditional semantic theories of meaning that focus on the nonverbal referents of words and neglect verbal stimuli as separate sources of control for linguistic behavior. An analysis of verbal stimulus control is presented, along…

Effective intraverbal responding often requires control by multiple elements of a verbal stimulus. The purpose of this study was to examine the emergence of such intraverbal relations following tact instruction with compound stimuli and to analyze any resulting error patterns. Participants were seven typically developing children between 3 and…

A common characteristic of the language deficits experienced by children with autism (and other developmental disorders) is their failure to acquire a complex intraverbal repertoire. The difficulties with learning intraverbal behaviors may, in part, be related to the fact that the stimulus control for such behaviors usually involves highly complex…

Axe (2008) speculated that some instances of intraverbal responding might be associated with limited or delayed acquisition because they require discrimination of multiple components of verbal stimuli. Past studies suggest that acquisition of responses under control of complex, multicomponent antecedent stimuli (e.g., conditional or compound…

The effects of two types of mands on participants' adherence to instructions were examined across two groups using procedures based on Hackenberg and Joker ("Journal of the Experimental Analysis of Behavior" 62:367-383, 1994). Participants were presented with instructions describing a pattern of responding for producing points later…

The present study evaluated the emergence of intraverbal responses following tact training with three adolescents diagnosed with autism spectrum disorders. Participants were taught to tact the name of a cartoon character (e.g., "What is the name of this monster?" ["Simon"]) and that character's preferred food (e.g., "What food does this monster…

A controversial issue in anaphoric processing has been whether processing preferences of anaphoric expressions are affected by the antecedent's grammatical role or surface position. Using eye tracking, Experiment 1 examined the comprehension of pronouns during reading, which revealed shorter reading times in the pronoun region and later regions…

The Picture Exchange Communication System (PECS) is an alternative/augmentative communication protocol designed to help children and adults with autism and related disabilities to engage in functional communication. The protocol was developed over a number of years and was based on Skinner's analysis of verbal behavior. Publications about the…
