Language generativity can be described as the ability to produce sentences never before said, and to understand sentences never before heard. One process often cited as underlying language generativity is response generalization. However, though the latter seems to promise a technical understanding of the former at a process level, an…

Every article on stimulus equivalence or derived stimulus relations published in the "Journal of Applied Behavior Analysis" was evaluated in terms of characteristics that are relevant to the development of applied technologies: the type of participants, settings, procedure automated vs. tabletop), stimuli, and stimulus sensory modality; types of…

The current study evaluated the turn-taking skills of preschoolers with disabilities who participated in a social communication intervention that targeted initiations, responses, and turn-taking skills, and taught children to repair and revise and to avoid interruptions and overlaps. Ten children who enrolled in an inclusive at-risk classroom met…

Additive effects of publicly posting individual feedback following group goal-setting and feedback were evaluated. The turn-signal use of pizza deliverers was studied in a multiple baseline design across two pizza stores. After baseline observations, pizza deliverers voted on a group turn-signal goal and then received 4 weeks of group feedback on…

The current work explored the conditions under which infants generalize spatial relationships from one event to another. English-learning 5-month-olds habituated to a tight- or loose-fit covering event dishabituated to a change in fit during a "containment" test event, but infants habituated to a visually similar "occlusion" event did not. Thus,…

Children with autism often lack complex socially expressive skills that would allow them to engage others more successfully. In the present study, video modeling was used to promote appropriate verbal comments, intonation, gestures, and facial expressions during social interactions of three children with autism. In baseline, the children rarely…

A limited number of studies have investigated the effects of behavioral skills training (BST) on staff acquisition and generalization of discrete trial teaching (DTT) and student behavior. BST was used to improve three staff's use of DTT interactions with four children with autism. A multiple baseline design across participants was used to assess…

The conditions under which symmetry and equivalence relations develop are still controversial. This paper reports three experiments that attempt to analyze the impact of multiple-exemplar training (MET) in receptive symmetry on the emergence of visual-visual equivalence relations with a very young child, Gloria. At the age of 15 months 24 days…

R. N. Shepard (1987) has proposed a universal exponential law of stimulus generalization, yet experimental data are often Gaussian in form. Theories have been proposed to reconcile the discrepancy, but as proposed here, a simple discrete diffusion process may underlie both types of gradient. (SLD)

Four preschool children (with and without disabilities), who often responded inappropriately to questions, participated in the current study. Pretest results were used to create sets of questions that the children either did or did not answer correctly (i.e., known and unknown questions). We then sequentially taught two different responses to a…

Young children with autism have deficits in initiating and responding to joint attention bids. This study was designed to examine a parent-implemented intervention targeting joint attention responding in children with autism. Parents were trained to increase their joint attention bids using behavior analytic techniques to facilitate appropriate…

The present study tests a model of category effects upon stimulus estimation in children. Prior work with adults suggests that people inductively generalize distributional information about a category of stimuli and use this information to adjust their estimates of individual stimuli in a way that maximizes average accuracy in estimation (see…

The Center for Epidemiologic Studies-Depression (CES-D) Scale is among the most commonly used measures of depressive symptomatology. Despite this, a paucity of research has been undertaken to examine the psychometric properties of responses to this scale. This meta-analytic study examined previously published studies of caregiving to identify…

The bulk of the existing literature emphasizes the use of phonemic/phonetic based instruction to enhance generalization between reading and written language. However, phonetically irregular words are common in English and may require the use of whole word approaches. This study examined generalization between from reading to spelling and from…

A model for describing dynamic processes is constructed by combining the Rasch model with the concept of structurally incomplete designs. This is accomplished by mapping each item on a collection of virtual items, one of which is assumed to be presented to the respondent depending on preceding responses or feedback. (SLD)
