In 3 experiments, 3-month-old infants were trained to move an overhead mobile by kicking 1 of their feet in the presence of a distinctive visual (crib bumpers) and auditory (music) context. In Experiment 1A, 5-day but not 1-day retention was disrupted if either or both elements of the context present during the retention test were novel. In…

This study investigates the practice of presenting multiple supporting examples in parallel form. The elements of parallelism and its use in argument were first illustrated by Aristotle. Although real texts may depart from the ideal form for presenting multiple examples, rhetorical theory offers a rationale for minimal, parallel presentation. The…

Four experiments were conducted to investigate the relationship between the binding of visual features (as measured by their after-effects on subsequent binding) and the learning of feature-conjunction probabilities. Both binding and learning effects were obtained, but they did not interact. Interestingly, (shape-color) binding effects…

Visual perceptual skills of deaf and normal hearing adults were measured using the Eriksen flanker task. Participants were seated in front of a computer screen while a series of target letters flanked by similar or dissimilar letters was flashed in front of them. Participants were instructed to press one button when they saw an "H," and another…

A forced-choice reaction-time (RT) task was used to examine voluntary visual orienting among children and adolescents with trisomy 21 Down syndrome and typically developing children matched at an MA of approximately 5.6 years, an age when the development of orienting abilities reaches optimal adult-like efficiency. Both groups displayed faster…

Reaction times and picture evaluations by 18 adults with hearing loss were compared with those of 18 matched controls during two visual priming tasks. In Task 1, participants reacted to sexual and plant target pictures (while influenced by similar preceding pictures) by pressing "sex" or "plant" buttons. In Task 2, they evaluated target Japanese…

Derived conditional discrimination was evaluated in 2 men with mental retardation whose language was limited to gestural requests. In each conditional-discrimination task, sample stimuli were arbitrary visual forms and comparison stimuli were black squares presented in 2 of the 4 corners of a computer screen. Subjects learned to select 1 position…

This report describes the findings of an analysis of a series of action research projects conducted by Vigo County School Corporation at Terre Haute South Vigo High School (hereinafter referred to as South Vigo). During the 2008-2009 school year, 19 teachers at South Vigo participated in independent action research studies regarding the extent to…

When asked questions, children often avert their gaze. Furthermore, the frequency of such gaze aversion (GA) is related to the difficulty of cognitive processing, suggesting that GA is a good indicator of children's thinking and comprehension. However, little is known about how teachers detect and interpret such gaze signals. In Study 1 teaching…

Recent eye tracking studies of face processing have produced differing accounts of how and whether children with autism differ from their typically developing peers. The two groups' gaze patterns appear to differ for dynamic videos of social scenes, but not for static photos of isolated individuals. The present study replicated and extended…

Although it is acknowledged that adults integrate features into a representation of the whole face, there is still some disagreement about the onset and developmental course of holistic face processing. We tested adults and children from 4 to 6 years of age with the same paradigm measuring holistic face processing through an adaptation of the…

Patients diagnosed with Autism Spectrum Disorder, show impaired integration of information across different senses. The processing-level from which this impairment originates, however, remains unclear. We investigated low-level integration of auditory and visual stimuli in subjects with Autism Spectrum Disorder. High-functioning adult subjects…

An investigation was conducted into the visual and auditory temporal processing profiles of two groups of 4- to 6-year-old children: "pre-alphabetic" children, who showed no alphabetic ability (failing to read any non-words in a test), and those who demonstrated some alphabetic ability. This "alphabetic" group showed higher scores in reading and…

Background: Previous research suggested that persons with Down syndrome (DS) used a different strategy to drum than typical adults. Methods: The present study examined continuous bimanual drumming strategies in response to different instructions in 10 persons with DS, 10 mental age-matched and 10 chronological age-matched groups. The drumming task…

Obesity is a growing epidemic in the United States. Children who are overweight tend to participate in fewer activities, to withdraw from social situations, and to be less physically active than their normal-weight peers. Additionally, they have lower self-image and often suffer from depression. Research on children's perceptions of overweight…
