The role of executive functions in attention deficit hyperactivity disorder (ADHD) varies considerably depending on the models of ADHD. We examined the interrelationship of two major executive functions (i.e., inhibition and working memory) with behavioral, emotional, and school problems in a group of children who had a comprehensive…

This article examines the subculture of violence thesis as it relates to female street sex workers in Miami.

This study examined associations between sociometric status and friendship quality using observational and questionnaire data from 139 fourth-grade girls and their friends.

Recent studies show that national control of K-12 curriculum yields important payoffs in terms of greater curricular coherence and, as a result, higher test performance on international tests such as those used in the Third International Mathematics and Science Study. This paper examines the connection between national control of curriculum and…

The present study assessed mastery behaviors in toddlers with physical impairment during object and social play interaction with their parents. Poor mastery motivation in object play of children with physical impairments has been attributed to difficulty in independently structuring tasks, limited experience in play effectiveness, and frequent…

A new method of analyzing mathematics attitudes through symbolic drawings, situated within the field of Jungian-oriented analytical psychology, was applied to 52 preservice elementary teachers before and after a mathematics methods course. In this triangulation mixed methods design study, pretest images related to past mathematics experiences…

Six item bias detection techniques (distractor analysis, the Mantel-Haenszel procedure, Angoff's delta plot, Angoff's modified delta plot, Stricker's partial correlation index, and direct comparison of item difficulties) were compared for their ability to identify biased items at three stages of test development. The techniques were applied to…

The purpose of this study was to use secondary analysis of an Australian database known as the Second International Science Study (SISS) to examine the role of student, school and home factors in explaining student differences in science achievement, especially on sex differences. Student characteristics investigated in the study included home…

Researchers have used children's self-reports to investigate the conditions under which children seek and give help. Little attention has been given to examining the predictive value of such measures, even though investigators in other domains have found discrepancies between self-reports and observed behavior. Two studies were conducted in which…

The purpose of this study was to examine the differential effects of computer conferencing on expository writing for undergraduate students (n=109) of seven intelligence types (linguistic, logical/mathematical, spatial, bodily/kinesthetic, musical, interpersonal, and intrapersonal). Students were assigned to four treatment groups that provided…

To answer several questions about the Ohio statewide high school proficiency testing program, correlations of student performance on the ninth-grade proficiency test with other measures of reading and mathematics were studied for approximately 4,600 students in the Cleveland (Ohio) City School District. The performance of students from higher…

The developmental pattern in the relationships among mothers' beliefs about structure, autonomy, control, and intelligence was studied, addressing: (1) how mothers' scaffolding beliefs and conceptions of intelligence are related; (2) the relationship of these maternal beliefs to children's age and achievement; and (3) the relationship between…

The purpose of this investigation was to examine the cognitive styles of 144 education majors over a 2-to-3-year period culminating in the internship experience. The hypothesis was that scores on the Group Embedded Figures Test (GEFT) following the internship would be more field-independent, and the intent was to document the influence of…

The effects of innovation on leadership abilities have not been widely investigated. Although diffusion of innovation theory has existed for some time, there is a need for more research detailing the relationship between innovation and transformational leadership. In a survey of organizational members (N = 294), innovation was significantly…
