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)

This study examined effectiveness of a constant time delay (CTD) procedure in teaching social studies and health facts to five adolescents with learning or behavioral disorders. Students were given praise with and without additional information. Results indicated CTD procedures were reliable and effective, and students acquired nontargeted as well…

Infants' visual fixations were monitored while they viewed predictable and unpredictable sequences of stimuli. Analyses of anticipatory fixations indicated that by two months of age, infants form expectations for the reappearance of visual stimuli positioned opposite to each other. By three months, infants rapidly form expectations for asymmetric…

Twenty-two elementary-aged children with reading difficulties were administered multiple assessments, including the Matching Familiar Figures Test (MFFT), Simple Reaction Time, and Complex Reaction Time. Results did not support a relationship between impulsivity, as measured by the MFFT, and academic progress in a classroom setting. (Author/JDD)

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)

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…

Finds a significant correlation between Reaction Time (RT) and reading ability; however, the zero-order correlation between RT and word recognition ability was largely due to variance shared with phonological awareness and general cognitive ability. Concludes RT explained almost no unique variance after phonological sensitivity and general…

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 research investigated the time course of integrative semantic processing during sentence processing. Reading time was measured on sentences containing an NP composed of an adjective and a noun whose combined meaning was plausible or anomalous (Experiment 1) or was typical or atypical (Experiment 2). The noun in the NP was either plural or…

Auditory and auditory-visual (AV) speech perception skills were examined in adults with and without language-learning disabilities (LLD). The AV stimuli consisted of congruent consonant-vowel syllables (auditory and visual syllables matched in terms of syllable being produced) and incongruent McGurk syllables (auditory syllable differed from…

The authors report on a cross-linguistic investigation of the reading skills of 6- to 11-year-old children of English (an opaque orthography) and of Dutch (a transparent orthography). Dutch children were relatively more accurate and faster than English children of the same age at reading words and nonwords and also faster to complete phoneme…
