Although a considerable amount is known about the development of object manipulation during the 1st year, less is known about how infants manually explore surfaces and relate objects to surfaces. To address these issues, 60 infants (20 each at 6, 8, and 10 months of age) were presented hard and soft objects on tabletop surfaces, which varied in…

This study investigated perceptions of differing generations of Ashkenazi Jewish Americans regarding the concept of their "race," and also their understanding of their "White privilege." In labeling their race, participants constructed an overall spectrum of terms, some reflecting a chosen ethnoracial identity and some reflecting a given…

This article reviews current knowledge about how the visual system recognizes letters and words, and the impact on reading when parts of the visual system malfunction. The physiology of eye and brain places important constraints on how we process text, and the efficient organization of the neurocognitive systems involved is not inherent but…

We examined the effect of perceptual training on a well-established hemispheric asymmetry in speech processing. Eighteen listeners were trained to use a within-category difference in voice onset time (VOT) to cue talker identity. Successful learners (n = 8) showed faster response times for stimuli presented only to the left ear than for those…

We investigated Gardner's "Theory of Multiple Intelligences" in a sample of 200 adults. For each of the hypothesized eight "intelligence" domains--Linguistic, Logical/Mathematical, Spatial, Interpersonal, Intrapersonal, Musical, Bodily-Kinesthetic, Naturalistic--we selected two tests based on Gardner's description of its content. Factor analysis…

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…

Using a simple change detection task involving vertical and horizontal stimuli, I. M. Thornton and D. Fernandez-Duque (2000) showed that the implicit detection of a change in the orientation of an item influences performance in a subsequent orientation judgment task. However, S. R. Mitroff, D. J. Simons, and S. L. Franconeri (2002) were not able…

In this article, we detail how to produce two inexpensive micromanipulators that offer high precision (approximately 25 micrometers) along a single axis of movement. The more expensive of the designs provides improved versatility along multiple axes. Both manipulators offer substantial savings over commercially available micromanipulators with…

The author uses the example of a text a student was not allowed to display on his course Web site to explore how and why institutional ideologies particular to the historical development of composition and creative writing--especially when viewed in conjunction with current copyright law--render students' multimedia compositions illegitimate. He…

The aim of the 2018 International Association for Development of the Information Society (IADIS) Cognition and Exploratory Learning in the Digital Age (CELDA) conference was to address the main issues concerned with evolving learning processes and supporting pedagogies and applications in the digital age. There have been advances in both cognitive…

The Child Development Program at John Adams School in North Brunswick, New Jersey, was designed to be an immediate intervention for children with learning problems in the early elementary grades. This two-volume guide describes the work done in the program and how the program can be replicated. The first book details characteristics of the…

THE MAJOR PURPOSE OF THE STUDY WAS A TRIAL AND EVALUATION OF AN EXPERIMENTAL CURRICULUM UNIT DESIGNED TO PROVIDE A STRUCTURAL PROGRAM IN SOCIAL PERCEPTION AND BEHAVIOR FOR EDUCABLE MENTALLY RETARDED ADOLESCENTS. THE PROGRAM WAS DEVISED IN THE FORM OF SEQUENTIAL SIMULATION OR ILLUSTRATIONS LEADING TO SKILLS IN PERCEIVING WHICH CUES ARE RELEVANT,…

The effects of various rates of presentation were studied in combination with massed and spaced, concurrent and nonconcurrent, overt and covert practice modes on film-mediated perceptual performance. Selected values of the independent variables were investigated within a 3x3x2 factorial design, and the experimental treatments were randomly ordered…

In the present study, language development of Dutch children with a cochlear implant (CI) in a bilingual educational setting and Flemish children with a CI in a dominantly monolingual educational setting is compared. In addition, we compared the development of spoken language with the development of sign language in Dutch children. Eighteen…

Many organizations strive to improve performance by creating and marketing new products and/or services. Understanding why some new products and services succeed while others fail is critical to managers and marketing researchers. Diffusion of innovation theory addresses the reasons for, and rate of, the adoption of new ideas, products, and…
