Background: Several theorists maintain that exact number abilities rely on language-relevant processes whereas approximate number calls on visuo-spatial skills. We chose two genetic disorders, Williams syndrome and Down's syndrome, which differ in their relative abilities in verbal versus spatial skills, to examine this hypothesis. Five…

Background: Although children of bipolar parents are at heightened risk for developing emotional disorders, the processes underlying this vulnerability are not well understood. This study examined biases in the processing of emotional stimuli as a potential vulnerability marker of bipolar disorder. Methods: Sixteen children of bipolar parents who…

Background: In this study several aspects of attention were studied in 237 nearly 6-year-old twin pairs. Specifically, the ability to sustain attention and inhibition were investigated using a computerized test battery (Amsterdam Neuropsychological Tasks). Furthermore, the Teacher's Report Form (TRF) was filled out by the teacher of the child and…

Purpose: Verb processing in early sequential Spanish-English bilinguals was investigated. Primary study goals were to identify potential patterns of development in relative levels of verb processing efficiency in a 1st (L1) and 2nd (L2) language and to investigate factors influencing cognitive control of the dual-language system in developing…

Although evidence is accumulating that the major reading difficulty dyslexics experience involves decoding and recognizing printed words, it is not clear that all dyslexics read poorly for the same reasons. A study investigated dyslexic children between 7 and 14 years of age to see if their reading errors and patterns of performance would enable…

This study attempted to evaluate the efficacy of time delay in increasing the academic response accuracy of moderately retarded adolescents. The time delay technique provided a means by which "cognitive organizers" could be taught to the students to mediate their behavior and improve academic performance. A modified multiple baseline…

Arima's Discrimination Learning Test (DLT) was reconfigured, made into a self-paced mode, and administered to potential recruits in order to determine if: (1) a previous study indicating a lack of difference in learning performance between white and nonwhites would hold up; and (2) the correlations between scores attained on the DLT and scores…

Spanish students in four inner-city high schools were first tested for conceptual tempo and then given the Test of Oral Proficiency in Spanish (TOPS). It is concluded that speeded and timed tests not only allow impulsive examinees to answer too soon, but often pressure normally reflective examinees to respond impulsively. (EJS)

Describes a study of students at Purdue University that examined the roles of gender, right- versus left-handedness, and mouse experience in preferences concerning the placement of icon buttons within hypermedia user-interface designs. Response rate is examined, order of presentation is discussed, and further research is suggested. (11 references)…

Background: Individuals with Down syndrome consistently perform less well than appropriately matched comparison groups on tests of verbal short-term memory, despite performing relatively well on non-verbal short-term memory tasks. However, it is not clear whether these findings constitute evidence for a selective deficit in verbal short-term…

When a fire breaks out in the twin cities of Lewiston and Auburn, Maine, the firefighter response time is just a bit quicker these days, thanks to student research at Bates College. When the alarm sounds, firefighters click on a computer map that tells them the size of the burning structure, the quickest route to the fire, the closest hydrant and…

This study was conducted to determine the relationship between teachers' experience and their perceptions of and reactions to problematic classroom situations. The purpose was to assist teacher educators to more adequately train beginning teachers who then would be better prepared to deal with problematic classroom situations. Subjects (N=49) were…

The associations among cognitive automatization, abstract problem solving, and educational performance were studied using 127 fourth to ninth grade students. A number of measures of fast, automatic, and fluent performance (FAF measures) were used: writing the alphabet; reading from a word list; and mentally performing arithmetic operations. The…

The major purpose of this study was to assess the degree to which cognitive style, as indexed by the Matching Familiar Figures Test (MFFT), is related to the way in which children respond to problems with social or interpersonal content. Fifty-two reflective and 64 impulsive first- and second-grade boys were presented with a number of stories in…

A questionnaire concerning attitudes toward the importance of communication skills and toward different modes of communication was administered to 290 incoming freshmen at the National Technical Institute for the Deaf. Students responded to one of two types of a 38-item questionnaire: a multiple choice, or Likert-type (strongly agree...strongly…
