Three adults with intellectual and visual disabilities were taught vocationally relevant tasks through the use of a self-operated verbal instruction system. Data showed that during the training all participants achieved percentages of correct task performance exceeding 90. Use of instructional clusters was effective in maintaining high levels of…

Behavioral pharmacology is a maturing science that has made significant contributions to the study of drug effects on behavior, especially in the domain of drug-behavior interactions. Less appreciated is that research in behavioral pharmacology can have, and has had, implications for the experimental analysis of behavior, especially its…

Discrepant effects of drugs on behavior maintained by temporal-discrimination procedures make conclusive statements about the neuropharmacological bases of timing difficult. The current experiment examined the possible contribution of a general, drug-induced disruption of stimulus control. Four pigeons responded on a three-component multiple…

We studied the choice behavior of 2 monkeys in a discrete-trial task with reinforcement contingencies similar to those Herrnstein (1961) used when he described the matching law. In each session, the monkeys experienced blocks of discrete trials at different relative-reinforcer frequencies or magnitudes with unsignalled transitions between the…

As part of an ongoing research program, the authors investigated the use of single-voiced narration and multi-voiced characterizations/monologues in a formative evaluation study of an instructional lesson on information processing. That lesson employed a design based on the use of content-related metaphors and a metaphorical graphical user…

Around 5 or 6 years of age, children begin to recognize that speakers who make ironic remarks do not believe what they literally say, but children of the same age do not show appreciation for the humor function of irony (Dews et al., 1996; Harris & Pexman, 2003). We investigated 7- to 10-year-old children's interpretations of verbal irony and…

Two groups of three students with moderate mental retardation were instructed using group procedures to compare static picture and video prompting simulation strategies. An alternating treatments design was used to compare individual student task acquisition and maintenance performances of purchasing and banking skills. The results indicated that…

This study examined the process of communication within the professional-family relationship by identifying and describing the types and patterns of talk during interactions between 15 families of young children with developmental delays and their respective early interventionists. Videotaped interactions of routine home visits were coded using a…

Conjunction errors occur when participants incorrectly identify as "old" novel test stimuli created by recombining parts of two study stimuli (parent items). Prior studies have reported that the conjunction error rate is higher when parent items are studied together than when they are studied apart (a parent proximity effect). In several…

Although the veridicality of unconscious perception is increasingly accepted, core issues remain unresolved [Jack, A., & Shallice, T. (2001). Introspective physicalism as an approach to the science of consciousness. "Cognition, 79," 161-196], and sharp disagreement persists regarding fundamental methodological and theoretical issues. The most…

The episodic buffer component of working memory is assumed to play a role in the binding of features into chunks. A series of experiments compared memory for arrays of colors or shapes with memory for bound combinations of these features. Demanding concurrent verbal tasks were used to investigate the role of general attentional processes,…

The purpose of this study was to investigate the relationships between music training and musical complexity and focus of attention to melody or harmony. Participants (N = 192) were divided into four groups: university jazz majors (n = 64), other university music majors (n = 64), high school instrumentalists (n = 32), and junior high…

Evoked potential studies have demonstrated that musicians have the ability to distinguish musical sounds preattentively and automatically at the temporal, spectral, and spatial levels in more detail. It is however not known whether there is a difference in the early processes of auditory data processing of musicians. The most emphasized and…

Numerous instructional techniques have been used to teach sight word reading skills to individuals with developmental disabilities. The results of research incorporating paired associate instruction, in which familiar pictures are paired with unknown print stimuli, suggest that pictures ''block'' (i.e., interfere with) learners' ability to…

Despite the developing infusion of three-dimensional, technological imagery, little has been done to explain the effects of two-dimensional versus three-dimensional imagery on the learning process. This study examined the effects of two-dimensional stimuli and three-dimensional stereoptic stimuli on spatial representation in drawings. A scene was…
