The Test of Visual Perceptual Abilities and the Test of Spatial Perception in Sign Language were developed and administered to 682 hearing-impaired students, aged 8-18. Results showed that a significant relationship exists between visual perceptual abilities and the ability to comprehend the essential spatial components of sign language.…

Two studies of adults between the ages of 18 and 87 were conducted to determine the relations among age, motor speed, perceptual speed and 3 measures of cognitive performance: study time, decision time, and decision accuracy. Results indicated that increased age was associated with lower accuracy as well as with longer study and decision time.…

The results of an experiment in teaching engineering graphics using the traditional lecture-homework-laboratory technique are compared to a newer lecture homework proposal. Although the newer method reduces professor-student contact, it may prove to be as effective as the older method requiring laboratory instruction. (KR)

Presented is a proposed formula for determining the bearing angle and the slope angle for the line of intersection using the strike and dip angles of two given plane segments. Included is the development of the formula and three example problems. (KR)

Two graphics interface packages, PHIGS and HOOPS, are examined. A comparison of the two packages is made in light of the Iowa State University College of Engineering's need for educational software. Conclusions based on programing experience using both PHIGS and HOOPS are presented. (KR)

Factor analysis performed on the Wechsler Intelligence Scale for Children-Revised (WISC-R) for 252 subjects (ages 6-16), who were mentally handicapped, slow learners, or learning disabled, identified 3 factors: verbal-conceptual, perceptual-spatial, and distractibility-short-term memory. Findings suggest that the factor example can be used to…

Examines the relationship between the academic performance of 347 elementary school children and a number of cognitive and social factors. A path analysis indicated that the girls' overall higher performance was a result of greater social responsiveness and compliance with adult direction, whereas achievement among the boys was related to greater…

Spatial aptitude tests designed for elementary school children were given to third-grade students from both suburban and rural schools in Pennsylvania. Results were scrutinized by the declared favorite subjects of the participants and organized by gender. Students who preferred science and mathematics did better on spatial tests than students who…

Examines verbal/linguistic and visual/spatial intelligences and their relationship to Montessori education. Aligns Gardner's philosophy of these two intelligences with Montessori's specific counterparts in the prepared environment. Defines assessment in light of observation and the definitive clarity of Montessori activities. Suggests that…

This study surveyed social work educators about the importance of multiple intelligences for social work practice and social work education. The sample consisted of 91 faculty members who responded to an online survey that asked them to rate the importance of 7 intelligences (linguistic, logical-mathematical, musical, bodily-kinesthetic, spatial,…

Background: Accumulating evidence supports methylphenidate-induced enhancement of neuropsychological functioning in attention deficit hyperactivity disorder (ADHD). The present study was designed to investigate the acute effects of the psychostimulant drug, methylphenidate (MPH), on neuropsychological performance in stimulant naive boys with ADHD.…

Three-dimensional spatial skills have been shown to be critical to success in engineering and other technological fields. Well-developed 3D spatial skills are particularly important for success in engineering graphics courses. Further, 3D spatial skills of women lag significantly behind those of their male counterparts, which could hinder their…

This study was an investigation of the effects of sequenced Kodaly literacy-based music instruction on the spatial reasoning skills of kindergarten students. Subjects in the pretest-posttest control group design were 54 kindergarten students who were enrolled in three kindergarten classes in a rural elementary community school. Experimental group…

This article examines whether various cognitive abilities are associated with symptoms of ADHD. Cognitive ability is conceptualized using Cattell-Horn-Carroll (CHC) theory as measured using the Woodcock-Johnson Tests of Cognitive Ability (3rd ed.). This article also examines whether test session behavior mediates the association between cognitive…

We report on a longitudinal study designed to assess possible sex differences in math achievement, math ability, and math-related tasks during the primary school age years. Participants included over 200 children from one public school district. Annual assessments included measures of math ability, math calculation achievement scores, rapid naming…
