Research on adult memory for nonverbal representations has found a significant age-related decrement in performance. To investigate age differences in adult locational versus featural information in visual memory, 90 adult women (29 young women with a mean age of 21; 30 middle aged women with a mean age of 43; and 31 older women with a mean age of…

Meta-analysis techniques were used to summarize the results concerning gender differences reported in doctoral dissertations on visual spatial skills. Dissertations were chosen because they are not subject to the selection process of journals, which may bias results toward large effects. An analysis of 150 independent data points in 43…

The impact on learning performance of a notetaking strategy called the Directed Overt Activity Strategy (DOA) was evaluated on three types of instructional tasks: spatial learning, simple concept learning, and complex concept learning. One hundred volunteer freshman psychology students from Ohio State University used either the DOA or their own…

This study investigated place location learning from a simulated environmental exploration experience in terms of two variables: gender (both cognitive and affective effects) and presence and/or type of accompanying map. Subjects were 120 fourth and fifth grade students, who were randomly selected and assigned after stratification on gender. The…

This study was designed to determine if the final grade in college biology at a suburban community college was a true measure of student's knowledge. One hundred and seventy undergraduates taking a semester course in biology took part in the study. This population was randomly separated into a control, placebo, and experimental group. The progress…

Structural covariance models that would explain the correlations observed among mathematics achievement and participation measures and related cognitive and affective variables were developed. A sample of college calculus students (N=268; 124 females and 144 males) was administered a battery of cognitive tests (including measures of spatial-visual…

Effects of Logo instruction on the performance of 21 grade 2 and 26 grade 4 Canadian students on a map reading task was examined in a pretest-treatment-posttest design with controls. Logo instruction was implemented through a series of four graduated, sequential Logo Microworld programs which were used by students daily for 7 months. The control…

Two experiments were conducted to assess the performance of freshmen chemistry students with poor spatial visualization skills. In the first experiment, 31 chemistry students with academically deficient backgrounds completed a diagnostic test of their ability to visualize and interpret pictorial representations of simple molecular structures. At…

This paper considers the feasibility of incorporating research results from cognitive science into the modeling of performance on psychometric tests and the construction of test items. The paper focuses on the feasibility of modeling performance on a three-dimensional rotation task within the context of Item Response Theory (IRT). To test the…

Language syntax is discussed, followed by an overview of algbraic syntax. Evaluating algebraic expressions was chosen as the means to investigate the psychological basis of syntactic skills. Subjects' ability to perform evaluative tasks appropriately using standard algebraic notation was ascertained; then similar tasks were presented using a…

Designed to be infused with existing social studies courses and programs of instruction, this concept-based, skills-oriented curriculum for teachers of students in grades 5-12 provides opportunities for students to develop basic map skills enabling them to mentally develop spatial relationships between diverse global environments and/or culture…

Television wide-angle lenses expand distances and increase apparent velocity, while long lenses compress space and reduce apparent velocity. Based on these assumptions, a study was conducted (1) to examine the ability of viewers of different ages to recognize how lenses change the "real world" they project and (2) to extend Jean Piaget's…

The study involving 60 learning disabled (LD) and 30 normal achieving seventh through ninth graders was designed to identify adolescents homogeneously defined as exhibiting a "specific learning disability in arithmetic" and to determine if the cognitive processes (visual-spatial, visual-reasoning, and visual-memory) are related to the academic…

This longitudinal study was designed to investigate the nature and extent of sex differences in both verbal and spatial abilities among black and white children. Six scales of early cognitive functioning were administered at three times (at 8 months, 4 years and 7 years) to 3,013 children. Two major hypotheses were examined: (1) if cognitive…

Thinking-aloud protocols of human problem solvers working on geometry problems are presented and discussed. Protocols were obtained from six individuals working on nine different problems in which constructions were used. Nineteen protocols are presented with annotation and discussion, and other protocols are summarized. The primary purpose of the…
