An experimental analysis of generative manding in preschool children

This study examined the development of mands for missing objects. Two female children and two male children (ranging from 2 years, 1 month to 3 years, 5 months) were selected on the basis of screening probes that indicated an absence of manding. A mand probe consisted of instructions to complete a response chain when one of the needed objects was missing. For every response chain, each child was:. (a) taught to label (tact) the objects, (b) then taught to use the objects in reinforced response chains, and (c) then given mand probes for the stimuli just trained. Results for all children indicated correct responses· to tact and operation probes but incorrect responses to the mand probes. After pretraining, mands were trained one at a time until generalized manding developed. The efficacy of the training procedures was established by using a multiple probe design. These results are discussed in terms of mands and tacts representing distinct response classes

Child language, the emergence of vocal requests for absent objects as a function of preferred operations and

Intellectually normal young children learn to request absent but needed objects which they are able to name. The primary focus of my study of child language in context was to assess the motivational effect of operation or stimulus preference on Lhe rate of toy request acquisition and the formation of stimulus classes (stimulus equivalences) . Of 13 21- to 37- month-old day-care children screened for generalized request responses (novel requests) , 1 girl and 4 boys participated in the training program because they were unable to request. Two of 4 children who completed training showed some support for the effect of preference for two two-stimulus operations on request response acquisition. All 4 children emitted novel requests to generalization probes following request acquisition criterion for one most and one least preferred stimulus. Preference had no observable effect on generalization of requesting to untrained stimuli. Additionally, I assessed and compared the cognitive-linguistic and adaptive-social maturity of those 5 children who were unable and those 8 who were able to request during preliminary request screening. The trained children tended to have a greater difference between their measured receptive and expressive language skills, and also they tended to have slightly lower scores on the Vineland Adaptive Behavior Scales: Communication, Daily Living Skills, Socialization, and Motor Skills Domains. I also tested the efficacy of a natural language paradigm using a distributed skills trial sequence with interspersed trials of known-items as an extension of Tidwell\u27s (1986) matching-to-sample, errorless learning procedure. Four within-subject replications of successful operation, name, and request acquisition are reported across 8 operations in support of his response chain methodology. I suggest that a battery of most of the developmental measures and request screening and training procedures tested in my study might be used by behavioral interventionists to assess and remediate delayed and/or inappropriate requesting among young normally developing children in a day-care setting
