The present experiment investigated the impact of contextually trained discriminations on gambling behavior. Nine recreational slot-machine players were initially exposed to concurrently available computerized slot machines that were each programmed on random-ratio schedules of reinforcement and differed only in color. All participants distributed…

The purpose of this study was to evaluate the effectiveness of using picture activity schedule books to increase on-schedule and on-task behaviors of children with moderate intellectual disabilities. Four students enrolled in a self-contained classroom participated in the study. Graduated guidance, system of least prompts, and verbal prompting…

There is a common assumption that hypermedia navigation is influenced by a learner's style of thinking, so people who are inclined to apply sequential and analytical strategies (left-thinkers) are thought to browse hypermedia in a linear way, whereas those who prefer holistic and intuitive strategies (right-thinkers) tend towards non-linear paths.…

This pilot study obtained baseline information on verbal and visual rhetorics to teach microscopy techniques to college biology majors. We presented cell images to students in cell biology and biology writing classes and then asked them to identify textual, verbal, and visual cues that support microscopy learning. Survey responses suggest that…

Background: Measuring the self-perceptions, thoughts, hopes and inner lives of persons with intellectual disabilities (ID) has long been a research challenge. Unlike objective or projective tests, semi-projective tasks may provide persons with ID with just enough structure or cues to convey their self-perceptions in a spontaneous and unbiased…

Purpose: The authors asked whether adolescents with Down syndrome (DS) could fast-map novel nouns and verbs when word learning depended on using the speaker's pragmatic or syntactic cues. Compared with typically developing (TD) comparison children, the authors predicted that syntactic cues would prove harder for the group with DS to use and that…

This article provides an overview of 3 approaches to peer-mediated intervention that have been effective in improving the social and communicative interactions among young children with autism and other developmental disabilities and their classmates without disabilities. These empirically supported peer-mediated interventions involve teaching…

A study investigated whether second language (L2) learners' participation in negotiation with native speakers (NSs) meets their needs for data on L2 lexical and structural features. The question was addressed through an analysis of NS utterances of negotiation that were produced as 20 native speaker-non-native speaker (NS-NNS) dyads carried out…

A descriptive study examined reading errors of emergent at-risk readers to determine which cueing system(s) they used initially, and whether or not there were changes over time in cues they used during reading. Running records of 30 first-grade children (participating in Reading Recovery programs at urban or suburban public elementary schools in…

For 15 years an ongoing research project at the University of Pittsburgh has focused on the effects of variations in visual complexity and color on the storage and retrieval of visual information by learners. Research has shown that visual materials facilitate instruction, but has not fully delineated the interactions of visual complexity and…

The relationship between preschool children's level of gender understanding and their ability to identify gender-linked attributes was examined. Participants were 26 3-year-old and 30 4-year-old children who were administered a single-cue gender labelling task, Slaby and Frey's (1975) gender constancy test, and the Peabody Picture Vocabulary Test.…

The paper examines the role of morphological (word) cues in reading and considers the implications for deaf students. Theories on the importance of decoding and morphological comparison in competent reading comprehension are reviewed, and studies on how successful deaf readers learn morphological cues are described. Findings show that deaf readers…

The effect of adding time for processing compressed speech and the effects of questions that gave adjunct pictures either a redundant or contextual function were investigated. Subjects were 144 fourth- and fifth-grade students randomly assigned to 24 groups. They listened individually to a 20-sentence story at either 225 or 300 words-per-minute…

Two experiments tested for effects of intralist cues upon recognition probability. Categorized and random lists were each tested, with targets appearing with zero, one or three intralist cues. Experiments showed substantial effects of trials and list type, but not of intralist context. (CHK)

This study examined how the practice of prepublishing prompts used on the writing section of the Graduate Record Examinations® (GRE®) General Test impacts test-preparation behavior, test performance, test validity, and examinee perceptions of the value of prompt prepublication. Researchers imposed modest experimental control over how participants…
