Aversive conditioning is an ideal model for studying cholinergic effects on the processes of learning and memory for several reasons. First, deficits produced by selective lesions of the anatomical structures shown to be critical for Pavlovian fear conditioning and inhibitory avoidance (such as the amygdala and hippocampus) resemble those deficits…

Two reading experiments investigated the extent to which the presence of phonemic repetition in sentences influenced processing difficulty during syntactic ambiguity resolution. In both experiments, participants read sentences silently as reading time was measured. Reading time on sentences containing a temporary syntactic ambiguity was compared…

Objective: Prior research suggests that individuals with ADHD overestimate their performance across domains despite performing more poorly in these domains. The authors introduce measures of accuracy from the larger realm of judgment and decision making--namely, relative accuracy and calibration--to the study of self-evaluative judgment accuracy…

Children with ADHD have difficulty understanding causal connections and goal plans within stories. This study examined mediators of group differences in story narrations between children ages 7-9 with and without ADHD, including as potential mediators both the core deficits of ADHD (i.e., inattention, disinhibition, planning/working memory) as…

The purpose of this study was to gather further insight into a previous investigation of the relationship between self-chosen and program-controlled segment length of an interactive videodisk program, and performance on post- and retention tests. The initial study by Verhagen, which questioned what is the optimum length of well-designed…

Knowledge representations and mental models from graphically presented information were investigated for 98 college students with different levels of mathematics experience. The subjects were drawn from a remedial algebra course (n=35), a second semester calculus course (n=35), and a calculus-based statistics course (n=28); they were all exposed…

Prior studies have often confounded linguistic and perceptual performance when evaluating deaf subjects' skills, a confusion that may be responsible for results indicating lesser recall ability among the deaf. In this series of studies this linguistic/perceptual confound was investigated in both the iconic and short term memory of deaf…

This study of 96 high school biology students investigates the effectiveness of visual instruction composed of simple line drawings and printed words as compared to printed-words-only instruction, visual tests, and the interaction between visual or non-visual mode of instruction and mode of testing. The subjects were randomly assigned to be given…

An experiment designed to test the generality of Paivio's two factor theory of meaning to sentence comprehension was carried out, and two scoring procedures were investigated: a verbatim score in which sentence elements had to be recalled exactly as they appeared in the original, and a substance score in which synonyms were accepted. The subjects…

Investigated relationships among metamemory, memory behavior, and memory performance of children aged 4 to 6 in two experiments. Results indicated an increase in preschoolers' ability to establish relationships between cues and targets even if these were not highly associated. (RWB)

Argues that the second language acquisition process involves two models, providing complementary accounts of different components which could be combined. An integrated model is proposed that would carry the acquisition-learning distinction of the Monitor Model while including the Neurofunctional Theory, which uses the distinction to describe the…

Compares the effects of mothers' mode of instruction on their children's memory test performance. Subjects were from the United States and Guatemala. A nongeneral, contextually influenced effect was found only for tests relying on verbal material and for children whose exposure to verbal instruction is not as extreme as in Western culture.…

No significant decline in performance occurred before age 50. Decline in Memory-For-Designs Test performance after age 60 is sufficient to suggest caution in the use of the test for evaluation of brain damage in the older patient. (Author)

Four experiments were carried out to examine the different recall strategies employed in a diagnostic test of visual sequential memory. The principal implication of the results is that good and poor readers may not differ with respect to visual memory but in their ability to employ a verbal labeling strategy. (Author/KC)
