This paper investigates how monitoring the time spent on a question in a test of basic mathematics skills can provide insights into learning processes, the quality of test takers' knowledge, and cognitive demands and performance of test items that otherwise would remain undiscovered if the usual test outcome of accuracy only format…

The Predominantly Inattentive (PI) and Combined (CB) subtypes of AD/HD differ in cognitive tempo, age of onset, gender ratio, and comorbidity, yet a differentiating endophenotype has not been identified. The aim of this study was to test rigorously diagnosed PI, CB, and typical children on measures selected for their potential to reveal…

Three experiments examined the effects of temporal attention and aging on masked repetition and categorical priming for numbers and words. Participants' temporal attention was manipulated by varying the stimulus onset asynchrony (i.e., constant or variable SOA). In Experiment 1, participants performed a parity judgment task and a lexical decision…

Children (n = 122) and adults (n = 200) with dyslexia completed rapid automatic naming (RAN) letters, rapid automatic switching (RAS) letters and numbers, executive function (inhibition, verbal fluency), and phonological working memory tasks. Typically developing 3rd (n = 117) and 5th (n = 103) graders completed the RAS task. Instead of analyzing…

This is the final report on a three year project designed to investigate the development of problem-solving strategies in elementary school children. In this project the personality of the child as it is reflected in problem solving style is examined. The hybothesis that reflective children are more competent problem solvers than impulsive…

Reports on an experiment designed to study the role of letter stems in the identification of printed words. The stemmed letters b,d,g,h,l,p and t were used. Results showed that the suppression of the letter's body has more detrimental effects on identification than the suppression of the stem. (Author/RM)

A study focused on the effect of assigned social decision rule on the process and product of mock jury deliberations. Subjects, 360 college students, were randomly assigned to six-member juries under three decision rule conditions: unanimity, five-sixths majority, and two-thirds majority. After viewing a videotape of a criminal trial, each subject…

This study determines whether children who see an object hidden in a location in one space can retrieve an analogous object hidden in an analogous location in a different space. Participants were 16 31-months-old and 16 38-months-old children. After a familiarization experience, half the children observed a stuffed dog hidden in a room, tried to…

Research was conducted to investigate the effects of contextual information on the speed and accuracy with which two general classes of inferences were verified by readers. These types of inferences were based on information in conversations that were or were not topically ambiguous, depending upon the amount of available contextual information.…

The results of this study support the assumption that long-term memory is not modified when a person performs a task utilizing an automatic process. Twelve university students performed an incidental learning task which consisted of scanning lists of words for either their own name, first names other than their own, words representing a unit of…

It has long been realized that tense is not a feature of the Chinese verb system, which is controlled by a set of particles attached to the verb or to the sentence as a whole. The various usages involving these particles have been listed and described, the author points out, but the system as a whole has not been clearly defined. He suggests the…

A series of four experiments was performed based on a model of human information processing. The model postulates four stages in the processing of an external stimulus: encoding (stage 1), central processing (stage 2), response selection, e.e. decoding (stage 3), and response execution (stage 4). The total reaction time can be decomposed into two…

Spanish-English bilinguals were tested for the speed with which they could recognize a word in one language as a member of a previously presented set of words in either language. Reaction time increased with the size of the presented set of words. Investigates the "translation effect" and its influence on information processing. (Editor/RK)

This study investigated the temporal orientation of delinquents and nondelinquents while controlling institutionalization. Four groups were selected: institutionalized delinquents; institutionalized nondelinquents; noninstitutionalized delinquents; and noninstitutionalized nondelinquents. The affective attitudes of the nondelinquents toward the…
