Reliability guides research design and is used as a standard for judging the credibility of findings and inferences. Using data gathered in a school health education curriculum evaluation as an example, possible errors in hypothesis testing are examined. Appropriateness of internal consistency as a measure of reliability is discussed and…

The study investigated personality and aptitude correlates of test-wiseness skills, which were measured by assessing the subject's ability to utilize deductive reasoning and item cues. Personality factors and aptitude were measured. Results indicated that cognitive variables have more power to predict test-wiseness scores than do personality…

An examination of methodological referencing patterns for actual physics, engineering, and sociology literature for the year 1983, using a Dunn planned comparison approach, indicates that physics differs from both engineering and sociology, while no difference was found between engineering and sociology. References are given in each sample…

Tests the claim to comprehensiveness of Bloom's taxonomy of educational objectives by analyzing educational objectives of some freshmen orientation programs and those connected with human developmental tasks. It is concluded that the taxonomy should be enlarged with a fourth domain: actual induction into tasks for which students are being…

Response data from 3,000 subjects to the SRA Attitude Survey were analyzed using the one-parameter and two-parameter logistic latent trait models. The effects of varying sample size on the accuracy of person and item parameters were investigated. (Author/BS)

Applies to the inclined-plane task Siegler's (1981) observation that performance on Piagetian tasks is governed by similar rule structures. Also replicates Siegler's original observations about the development on the balance-scale task and determines the consistency in children's rule usage across tasks. (Author/AS)

The present study compares the robustness of two different one way fixed-effects analysis of covariance (ANCOVA) models to investigate whether the model which uses a test statistic incorporating estimates of separate unequal regression slopes is more robust than the conventional model which assumes the slopes are equal. (Author/BW)

The regression-discontinuity design (RDD) offers the possibility of making inferences about causal effects from observations on selected groups. Data from such a design are considered to have a truncated bivariate distribution. For the RDD, maximum likelihood parameter estimation procedures and tests of hypotheses are presented. (Author/BW)

Occupational theory research has been associated with low statistical power and a high rate of Type II errors. To increase power, a procedure involving the partitioning of the decision region into three sections, based on the decision-theory approach to significance testing, is proposed. (SK)

Compares three methods of analyzing pairwise treatment differences in a multi-treatment experiment via computer simulation techniques. Under the equal n condition, the robustness of the conventional Tukey Wholly Significant Difference test (WSD) to heterogeneous variances was contrasted with two alternate techniques. Under unequal n conditions,…

It was suggested that thought changes cognitions to be more consistent with one's initial attitude direction and, therefore, results in attitude polarization. Specifically, it was predicted that polarization would be highest under thought with reality constraints absent, followed by thought with reality constraints present, followed by…

This study attempted to shed light on the role of items cued to be remembered in the forgetting of items cued to be forgotten. (Author)

Attempts to identify some of the more important concepts which "educated" Papua New Guineans used to describe the relationship between themselves and "uneducated" people. Explores the possible source of the attitudes being investigated. (Author/RK)

Subjects selected on the basis of their drinking histories (alcoholics, heavy drinkers, and social drinkers, N=24) were tested on a series of tasks in order to assess organizational processes in memory. (Editor)

In the context of the well-known fact that the higher stages of Kohlberg's sequence are less well-established than the lower, an exploratory investigation was carried out in a New Zealand teachers' college into the development of principled thinking in young adults and its association with various real-life experiences.
