The authors examine student cheating based on implicit and explicit definitions of cheating. Prior to being provided a definition of cheating, students reported whether they had cheated. Students were then provided a definition of cheating and asked to rereport their cheating behaviors. Results indicate that students do not understand what…

This study tested the hypothesis that positive career orientation can prevent adolescents from engaging in or escalating problem behaviour. A 1-year, longitudinal study was conducted on a sample of 234 junior-high and high-school students, who were 14.8 years old on the average in the beginning of the study. Using structural equation modeling, a…

This usability study evaluated users' perceptions of a multimedia prototype for a new e-learning tool: Anatomy of the Central Nervous System: A Multimedia Course. Usability testing is a collection of formative evaluation methods that inform the developmental design of e-learning tools to maximize user acceptance, satisfaction, and adoption.…

The author examined predictive relations among South Korean high school students' (N = 753) perceptions of their social-psychological environments, personal motivational beliefs, and academic behavior in math. Students' perceptions of their both classroom mastery and performance goal structures predicted their personal mastery goals. Perceptions…

The purpose of the present studies was to test the hypothesis that students' perceptions of parental bonding may be predictive of how individuals approach achievement situations. It was hypothesized that reports of parental overprotection would be predictive of elevated fears and subsequent stress and low achievement compared to perceived parental…

Findings of a study on the relation between 6-year-olds' attachment security and their mental representations of attachment relationships are reported. It was expected that infants whose attachment behavior seemed disorganized would be fearful of their attachment figures and experience themselves as helpless, and that these conditions would be…

Building communication theory in terms of three-variable relationships is a promising route to developing better theory, because three-variable relationships stand midway between sometimes overly simplistic two-variable relationships, and the more complex path analysis. The analysis of three-variable relationships has been done in many previous…

This research investigates how individual differences in strategic abilities affect problem solving and, more particularly, the extent to which hypothesis-generating skills predict effective hypothesis testing. Additional questions concerned the effects of content and timing of instructional advice on children's problem-solving strategies, and…

Arguments have recently been put forth that standard textbook procedures for determining the sample size necessary to achieve a certain level of power in a completely randomized design are incorrect when the dependent variable is fallible because they ignore measurement error. In fact, however, there are several correct procedures, one of which is…

The use of characteristic coding (dummy coding) is made in showing solutions to four multivariate problems using canonical analysis. The canonical variates can be themselves analyzed by the use of multiple linear regression. When the canonical variates are used as criteria in a multiple linear regression, the R2 values are equal to 0, where 0 is…

The role of biological maturity in behaviors in adolescents which most often are considered as negative by adults was investigated for a normal group of girls. (Author/LMO)

Discusses the concept of temperament interactions in the context of statistical interaction. Categorizes temperament interactions that involve temperament as an independent variable, as a dependent variable, or as both. Describes use of hierarchical multiple regression for the analysis of temperament interactions. (Author/CI)

Explores the relationship between the concept of uncertainty in information seeking within a model of the problem-solving process and variables derived from other models, based on longitudinal data collected in the United Sates and the United Kingdom that investigated the processes of mediated information retrieval searching during human…

Discussion of the use of selective dissemination of information (SDI) focuses on a study that proposed a model for evaluating the relationship between SDI and the number of publications authored by basic research scientists working in a corporate research and development (R&D) environment. Hypotheses and their findings are presented. (Seven…

On the basis of predictions from social comparison theory (L. Festinger, 1954) and informed by findings from the social comparison and eating disorder literatures, hypotheses were tested regarding the social comparison behaviors of women with eating disorder symptoms and their asymptomatic peers. Results indicated differentiating social-cognitive…
