Objective: To evaluate stimulant medication on symptoms and functioning for college students with ADHD using double-blind, placebo-controlled, crossover design. Method: Participants included 24 college students with ADHD and 26 college students without psychopathology. Lisdexamfetamine dimesylate (LDX) was examined for ADHD participants over five…

An examination of a nonverbally warm versus a nonverbally neutral teaching style on learning, question answering and question asking reveals that instructors who behave in a nonverbally warm style may increase learning and verbalness of Eskimo and white students in their classrooms. (Author/KM)

White and black fifth grade children, representing two levels of self-concept and social class, recalled nouns which they had prerated for likability. High self-concept white children recalled positively rated words more readily than negatively rated words, while high self-concept black children recalled negative words more readily than positive…

In these studies, authors sought to examine the role of mode of presentation in a verbal learning task, within the context of age-grade differences in two social groups. (Authors/CB)

Aptitude by treatment interactions are investigated in the context of paired associate learning. Individuals are grouped by preference for visual or verbal items on classifying lists of paired associates and these groups are used to predict performance on criterion lists. (DG)

The study sought to use Jensen's two-level theory of mental abilities to predict some hitherto unknown or unnoticed phenomena--facts about which the theory should yield clear-cut predictions and which are not as clearly predictable from other theories, though they may receive ad hoc explanations after the fact. From the two-level theory of mental…

This research contrasts the learning effects of an affective dimension of meaningfulness with the word-quality of consonant-vowel-consonant trigrams. Subject rated trigrams for both "association value"--having word-quality versus lacking word-quality--and "reinforcement value"--liking versus disliking the trigram regardless of word quality. Paired…

Recall lists were presented to 40 black lower class and 40 white middle class children in this experiment. The purpose of the study was to examine a possible explanation of the relatively poor performance of black and lower class children on tasks requiring abstract learning abilities. It was reasoned that the threshold for the production of…

The facilitation observed when paired-associates (PA) are presented or generated in a meaningful string is a phenomenon that is well-documented, and raises a number of developmental issues. The principal objective of the current research was to examine the relationship between performance on an auditory PA task and the linguistic components of…

Free recall, cued recall, and clustering performance of fourth grade lower socioeconomic black and white children is studied under four conditions of teaching: random presentation, random presentation plus instruction, blocked presentation, and blocked presentation with instruction of categorically related list. Results indicate that both recall…

After intensively studying for several years the thinking processes of members of a tribal group in Western Africa, the Kpelle, the authors examine the relation between culture and cognitive development. The following issues are discussed: (1) an analysis of the terms "culture" and "cognition"; (2) an ethnographic description of the Kpelle…
