Thirty-six elementary school students repeated short meaningful, long meaningful, and long nonce utterances in response to a visual cue. Nonstuttering, stuttering only, and stuttering-plus (concomitant speech and/or language problems) children responded differently to utterance length and meaningfulness. Results suggest that the three groups may…

Tested comprehension of syntactic structures by presenting each structure with both plausible and implausible content. Results revealed that cognitive nonlinguistic factors were important for comprehension and that errors and reaction time increased with age. The minimal contribution of neuropsychological factors to this decline suggests that the…

Fourteen undergraduate women (mean age 20) and 14 elderly women (mean age 70) executed a task requiring them to align a pointer with a target light in 5 positions. Elderly subjects had slower reaction and movement times. However, they were as capable as the younger women of correcting unanticipated movement errors. (SK)

A study of simple reaction time (SRT) and choice reaction time (CRT) in 71 Chicano adolescents suggests that Hick's model is appropriate for studying cognitive information processing in Chicanos. No age or sex differences were found for SRT or CRT, although there were some differences in SRT by family income level. (KS)

Redefines "Jensenism" in terms of the personal qualities and beliefs that have made Jensen a researcher of note, including tackling controversial topics with empiricism. Illustrates these aspects of "Jensenism" by recounting personal experiences with Jensen and his research. (SLD)

In addition to establishing the relationship between reaction time (RT) and intelligence, Jensen has explored the role of intraindividual variability and its genetic basis. Jensen's theories blend facts from behavioral research on RT with neurological events. (Author/SLD)

Reports results of experiments examining credibility of meta-information. Information provided by organizations of varying levels of credibility was used in decision making tasks. Effects were examined when there (1) was ample time and (2) were severe time constraints. Results confirmed that both source credibility and time influenced decisions,…

Children from grades 2, 3, 4, 6, and 8 made speeded, bimanual parity (odd/even) judgments of numerals. Response times indicated that from fourth grade on, parity information was retrieved directly from memory. By grade 3, children represented magnitude information as a left-to-right number line which was accessed obligatorily and, by grades 6 and…

Dutch-English bilinguals performed a generalized lexical decision task on triplets of items, responding with "yes" if all items wee correct Dutch and/or English words, and with "no" if one or ore of the items was not a word in wither language. Semantic priming effects were found in on-line response times. Event-related…

The current study aimed to test a Relational Frame Theory (RFT) model of analogical reasoning based on the relating of derived same and derived difference relations. Experiment 1 recorded reaction time measures of similar-similar (e.g., "apple is to orange as dog is to cat") versus different-different (e.g., "he is to his brother as…

The role of information processing deficits in poor readers of nonalphabetic scripts such as Chinese is not well documented. Here, we examined perceptual processing in good and poor readers of Chinese. Specifically, two groups of third grade children comprising 20 "good readers" and 19 "poor readers," drawn from a larger pool of 254 students, were…

Attention is a term that has been used to describe a broad range of topics in the sport and exercise literature (Nougier, Stein, & Bonnel, 1991). Research focusing on attention has included studies on selectivity, concentration, mental set, visual search, arousal, and information processing (Abernethy, 2001), and a variety of techniques (e.g.,…

Background: It has been repeatedly found that performance of children with attention deficit hyperactivity disorder (ADHD) is more impaired when a long inter-stimulus interval (ISI) is used than when a short ISI is used. According to the cognitive-energetic model, this may reflect difficulty in remaining in an optimal motor activation state…

Background: Whether selective attention is a primary deficit in childhood Attention Deficit Hyperactivity Disorder (ADHD) remains in active debate. Methods: We used the "perceptual load" paradigm to examine both early and late selective attention in children with the Primarily Inattentive (ADHD-I) and Combined subtypes (ADHD-C) of ADHD. Results:…

The authors examined the processing of phonological and orthographic word representations among 17 dyslexic and 16 normal college-level readers using Event-Related Potential measures. They focused on 2 early components--the P200 and the P300. The results revealed P200 and P300 components of lower amplitude and later latency among dyslexic readers…
