There is an ongoing debate over the psychophysical functions that best fit human data from numerical estimation tasks. To test whether one psychophysical function could account for data across diverse tasks, we examined 40 kindergartners, 38 first graders, 40 second graders and 40 adults' estimates using two fully crossed 2 × 2 designs, crossing…

Preparing students for entry into kindergarten is a key priority within the educational sector. Research has shown that students with lower levels of cognitive and socio-emotional competencies are less prepared for kindergarten entry and consequently perform more poorly on assessments in later grades (Duncan et al., 2007; Ensey Hoever, 2014;…

Findings from a study of 47 children between 3.5 and 12 years of age who received tonsillectomies at a children's hospital are presented. During a home visit before hospitalization, the child's adjustment, cognition, temperament, and family characteristics were assessed. Tonsillectomies were followed by an overnight stay at the hospital, and…

Described in the context of a computer simulation are highlights of a program of research focusing on the storage of mathematics problem solving information in young children's memory and the development of such knowledge structures in older children. Specifically discussed are the problem size effect, the network nature of the memory…

Explored were two issues raised by hypothesizing a direct link between number and functions: the relative contribution of distinct types of functions to numerical reasoning and the contribution of functions relative to the contribution of logic. Seventy-two children between the ages of 5 and 7 years were individually tested on measures of…

In an attempt to validate the findings of other researchers regarding the development of conceptual perspective taking, this study used Taylor's (1988) 2-tiered model to examine development of perspective taking among 40 3- to 5-year-olds. Participating were 22 males and 18 females from English-speaking backgrounds attending a preschool in…

Data from 80 junior high school students who completed the Assessment of Language and Reading Maturity (ALARM) test battery were used to delineate elements within the concept of mature reading comprehension. Stepwise multiple regression analyses were performed on the 15 ALARM test factors to isolate both the principal elements and the "trace…

This study examined the relationships between spatial ability, mathematics achievement, and sex for students in grades 2-7. Four spatial tests (embedded figures, serial integration, coordination of viewpoints, and rotation and development of surfaces) were used to measure spatial ability; sex and mathematics achievement, as measured by the Iowa…

This study presents research findings of a four year study intended to identify infant and family characteristics which, singly or in combination, predict developmental problems during preschool and school years. Predictors included a variety of measures of parental and neonatal biological conditions as well as measures of the quality of the…

Reported are results of a study that examined the relationships between university students' entry characteristics and achievement in biology. Variables judged most likely to be predictors of achievement were: (1) scholastic aptitude (quantitative and verbal); (2) level of cognitive development; (3) locus of control; (4) grade point average; (5)…

Eighth-grade students (n=42) were observed during five different life science problem-solving activities. Student interactions and thinking skills were recorded in relation to the problem-solving steps. A causal model was hypothesized and tested using path analysis procedures. The hypothesized causal model was adjusted based on path coefficients…

Since adolescent depression has become more frequently recognized, its manifestations need to be identified. To explore cognitive-perceptual distortions in depression as a function of generational (adolescent vs. adult) differences, 25 adult and 25 adolescent female inpatients diagnosed as depressed were administered the Beck Depression Inventory…

This study examined parental influence on children's cognitive skills by investigating characteristics of parent-child interaction in two tasks that required strategic activity and within which instruction in metacognition could occur. Subjects were 60 third and fourth grade girls and their mothers, who were divided into 2 experimental groups and…

The main goal of this study was to obtain insight about the factors that influence students' ability to learn during a field trip, in order to improve the planning and execution of learning field trips. The study was conducted in the context of a 1-day geological field trip for high school students in Israel. Three domains were tested by…

The potential utility of a college admissions test as a measure of the cognitive learning outcomes of general education is investigated. A residual form of the ACT Assessment was administered to a stratified random sample of 112 seniors at Tennessee Technological University. (Author/MLW)
