When subjects learn to associate two sample durations with two comparison keys, do they learn to associate the keys with the short and long samples (relational hypothesis), or with the specific sample durations (absolute hypothesis)? We exposed 16 pigeons to an ABA design in which phases A and B corresponded to tasks using samples of 1 s and 4 s,…

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…

According to the composite-stimulus control model (Weiss, 1969, 1972b), an individual discriminative stimulus (S[superscript D]) is composed of that S[superscript D]'s on-state plus the off-states of all other relevant S[superscript D]s. The present experiment investigated the reversibility of composite-stimulus control. Separate groups of rats…

Studies the ability of college women to generalize resistance to stress when learning lists of nonsense syllables. Subjects trained under one type of stress learned more easily under a second type of stress than did subjects trained under nonstressful conditions. Table, graph, and bibliography. (RW)

The primary thrust of this book is the presentation of two divergent models of man, the explicit and implicit philosophical assumptions which characterize each view, the conditions of learning compatible with each model, and the educational implications of each position. An introductory section considers the two models of man--the phenomenological…

At the Child Language Development Center at the University of Rochester, basic research in children's verbal behavior and the exploration of procedures for extending successful laboratory techniques to the typical preschool setting are being continued. Experiments in contingency management and the establishment of requisite antecedent behaviors…

This publication reports on research which has investigated phoneme acquisition and carry-over in a programmatic fashion. This research began with investigations of the effect of an extension of stimulus control of new phoneme responses through a systematic operant procedure. After quantifying the effect of such procedures in terms of stimulus…

While studies in learning and verbal behavior show that learning comes through paired-associate problems, they do not explain the acquisition of language. Three paradigms demonstrate mediation effect in paired-associate learning: response equivalence, stimulus equivalence, and chaining model. By reviewing children's language acquisition patterns…
