A model of graph comprehension is proposed including perceptual and memory processes. Multidimensional scaling (MDS), cluster analysis, and analysis of variance (ANOVA) were used to determine how college students with different mathematical experience read different types of bar graphs. Data were collected at the University of Oklahoma (Norman)…

This paper reports on a study which was conducted to determine the impact of color on learning. The entire seventh-grade class from a Midwest junior high school was used in the study. Each student was randomly assigned into one of four treatment groups: (1) color-cued presentation, color-cued assessment; (2) color-cued presentation, black/white…

The Stroop color-word test involves a conflict situation in which subjects are asked to say aloud the ink color used to print a color word on a card. Interference occurs when the ink color is in conflict with the color word, such as 'red' printed in green ink. On the other hand, little interference occurs when asked to name the color words…

The influence of story schema development on children's attention to television and memory of program content was examined in a study that involved two separate testing sessions. The expectation was that maximum effort would be given to program elements most central to comprehension of a television story and that this allocation strategy would be…

The Structure of Intellect Learning Abilities (SOI-LA) Test was administered to 244 Navajo students (second through eighth grades) at Leupp Boarding School in northern Arizona to determine behavioral characteristics in regard to intellectual and creative ability. Comparison of SOI-LA test scores of Leupp students with norm scores revealed 54 of…

A 40-item flexilevel test and a 40-item conventional test were compared using data obtained through (1) computer-administration of the two tests to three groups of college students, and (2) monte carlo simulation of test response patterns. Results indicated the flexilevel score distribution better reflected the underlying normal distribution of…

This study investigated correlations between the Qualitative score of the Porteus Maze Test and age and rates of recidivism of correctional institution inmates. In addition, the study was structured to provide answers to the following questions: (1) Is there a relationship between age and rates of recidivism and the Conformity-Variability score of…

Analyzes the task performance of two groups of readers--those who made gains and those who did not make gains in a remedial reading situation in order to determine their use of word identification cues. Shows that the gain group was more analytical of the test words and tended to use more units of varying size. (HOD)

Studied the imitation behavior of thirty 14- to 18-month-olds using peer and adult models in an elicited imitation paradigm. Indicated significant memory for 3-step behavior sequences both immediately after modeling and 1 week later compared with baseline performance. Found that children in the peer model group outperformed children in the adult…

It has been suggested that the ability to learn a foreign language is related to working memory. However, there is no clear evidence about which component of working memory may be involved. Two experiments investigated working memory problems in groups of seventh and eighth grade Italian children with difficulties in learning English as a second…

Simultaneous interpreting is a complex skill in which language comprehension and production take place at the same time in two languages. In this study, we examined performance on basic language and working memory tasks that have been hypothesized to engage cognitive skills important for simultaneous interpreting. The participants were native…

Two experiments investigated whether young and old adults can temporarily remove information from a capacity-limited central component of working memory (WM) into another component, the activated part of long-term memory (LTM). Experiment 1 used a modified Sternberg recognition task (S. Sternberg, 1969); Experiment 2 used an arithmetic…

Retinoid signaling has been recently shown to be required for mnemonic functions in rodents. To dissect the behavioral and molecular mechanisms involved in this requirement, we have analyzed the spatial and recognition working memory in mice carrying null mutations of retinoid receptors RAR[subscript [beta]] and RXR[subscript [gamma]]. Double…

Research reports on the nature of speech, instrumentation for the investigation of speech, and practical applications of speech research are included in this status report for the April 1-June 30, 1981, period. The 14 reports deal with the following topics: (1) electromyography as a technique for laryngeal investigation, (2) the phonatory…

Time-of-day effects on children's incidental visual memory for words and ability to solve verbal analogies were investigated. Thirty-six normal, learning disabled, and educable retarded children were assigned morning or afternoon learning/recall sessions. All showed afternoon superiority for superficially processed words, but no differences for…
