Objective: Executive dysfunction in ADHD is well supported. However, recent studies suggest that more fundamental impairments may be contributing. We assessed brain function in adults with ADHD during simple and complex forms of processing. Method: We used functional magnetic resonance imaging with forward and backward digit spans to investigate…

Experiment 1 investigated the effects of observational training in a social listener reinforcement game on participants' conversational units in non-instructional settings. Experiment 2 tested the effects of multiple exemplar instruction on the development of "empathy." The participants who had reader/writer levels of verbal behavior were selected…

In an investigation of discourse sensitivity, Catalan-speaking children aged 4 to 8 years were asked two different questions in a picture description task. One was a wide-focus question ("What is happening?"); the other was a narrow-focus question ("What is happening to 'the patient'?"). Children of all age groups displayed sensitivity to the…

In this cross-sectional study, we investigated whether the combination of the presence of callous-unemotional (CU) traits and emotional deficits to distressing stimuli, assessed by a computerized dot-probe task, enhanced the statistical prediction of aggression and delinquency in a sample of 88 detained and predominantly African-American (68%)…

The location of an object is often described by spatially relating it to a known landmark. The spatial terms used in such descriptions can provide various types of information. For example, projective terms such as "above" indicate direction but not distance, whereas proximal terms such as "near" indicate distance but not direction. Previous…

In this article, the authors describe a varied day of stimulating mathematics with key stage 2 learners--all revolving around chocolate. They used a variety of stimuli organized around the chocolate theme. A whole day was spent on using and applying mathematics, and the exercise proved to be enjoyable for both staff and pupils. The children…

This paper reports the results of a controlled field experiment in which voice communication was introduced into an existing online community (online gaming guilds within the popular game "World of Warcraft"), comparing a mix of voice and text with text only. Quantitative results suggest increases in liking and trust due to the addition of voice,…

Patterning is an essential skill in early mathematics learning, particularly in the development of spatial awareness, sequencing and ordering, comparison, and classification. This includes the ability to identify and describe attributes of objects and similarities and differences between them. Patterning is also integral to the development of…

A study investigated the processes used by bilinguals for organizing vocabulary by presenting subjects with bilingual word recognition tasks in two modalities (aural and visual) and using a repetition paradigm. Subjects were asked to decide whether a word presented to them was a nonsense word or a real word. Two separate experiments are described.…

The ability of 31 institutionalized trainable mentally retarded mongoloid and nonmongoloid subjects (mean IQ=27.5) to comprehend and imitate verbally presented sentences of varying levels of grammatical complexity was examined. Eight stimulus sentences were spoken for four pairs of pictures, simple declarative or kernel, negative, passive, and…

The purpose of this study was to determine the relationship of method of presentation, grade level, sex, and achievement within grade and sex to the various bases upon which children of low socioeconomic background classify geometric concepts. Two tasks were administered to 96 subjects in the fifth, eighth, and eleventh grades--32 at each grade…

A study investigated whether adult learners of a second language would judge grammaticality differently in visual and aural judgment tasks. Four groups were tested: English first-language, French first-language, English second-language, and French second-language. Results indicate judgments were slower and less accurate in the aural condition,…

Literacy is an issue for many low-income audiences. Using visual information processing theories, the goal was improving readability of a food behavior checklist and ultimately improving its ability to accurately capture existing changes in dietary behaviors. Using group interviews, low-income clients (n = 18) evaluated 4 visual styles. The text…

Writing exercises used as a means of reinforcing language presented and practiced in the spoken medium should include clear cues for the student that can stimulate and guide the writing of connected sentences. Three principles are suggested as being fundamental to the planning and use of effective exercises: (1) focus throughout should be on the…

The recent Irish film "Into the West" (1992) explores the myth of the West on two continents. Images from television and movies appear as a visual reference point within "Into the West"; the main characters, two young Irish boys, are fascinated with the American West of cowboys and Indians as depicted in countless Hollywood…
