A new self-report measure of impulsivity was developed to provide group administration and economy of scoring. An initial set of 26 items was constructed to tap various aspects of impulsivity, or the tendency to respond quickly without thinking. The items were administered to 346 male undergraduate students, primarily freshmen and sophomores. Item…

A rating scale to measure communication attitudes that distinguish stutterers from nonstutterers was tested for validity and reliability and used to determine when stutterers in speech therapy changed their attitudes to normal. (MYS)

This study investigated the relative benefits of peer-­controlled and moderated online collaboration during group problem solving. Thirty­-five self­-selected groups of four or five students were randomly assigned to the two conditions, which used the same online collaborative tool to solve twelve problem scenarios in an undergraduate statistics…

This paper reports a preliminary study on in-service Additional mathematics teachers' knowledge of kinematics concepts. A survey consisting of TRUE/FALSE questions was issued to the participating teachers. The questions were collations of the common misconceptions identified by some local Physics teachers among the local Physics students. The…

The author responding to criticism of an earlier article attempts to clarify his previous remarks on the reliability and validity of measures of body image in mentally handicapped persons. (LC)

An experimental test on beam walking (for balance), administered to 189 minimally brain injured and 226 educable mentally retarded (EMR) 8- to 13-year-old children, yielded results such as reliability estimates for the mean of three trials were high and there was greater performance reliability for EMR children.

A tailored testing model employing the beta distribution, whose mean equals the difficulty of an item and whose variance is approximately equal to the sampling variance of the item difficulty, and employing conditional item difficulties, is proposed. (Author)

The goal of this investigation was to derive a common battery of tests for both whites and negroes, and utilizing, if possible, uniform selection standards. (Author)

Both criterion-referenced testing and behavioral assessment share the basic assumption that test behavior is a sample rather than a sign. In addition, both types of assessment focus on response capabilities and performance in specified content domains. Although content validity has been traditionally recognized as essential to criterion-referenced…

One of the most persistent problems in the use of projective techniques is the need to develop objective, reliable and valid scoring systems. The sample consisted of 100 college students enrolled in an introductory psychology course. Ss were administered the DAPIR along with an extensive biographical questionnaire. Additionally, Ss were rated by…

The purpose of this paper is twofold: first, to provide a rationale for the design and use of a nonverbal coder-training system, and second, to present comprehensive coder-training packages theoretically based in the areas of (1) learning theory, (2) nonverbal research, and (3) instructional technology. Specifically, this training program is…
