Review states that the book gives an examination of the null-hypothesis significance test procedure as an integral component of data analysis of quantitative research studies in the social sciences. It is designed for the nonmathematics student who will be doing empirical studies involving the testing of substantive hypotheses. (SLD)

Evaluated the contribution of rule, exemplar, fragment, and episodic knowledge in artificial grammar learning using memorization versus hypothesis testing training tasks in 5 experiments involving a total of 163 college students. There was no evidence that memorization led to abstraction of rules or encoding of whole exemplars. Results support an…

Reports results of a study that was designed to empirically verify a system dynamics model that represents the relationship between dialog and structure as they relate to transactional distance and distance education. Topics discussed include discourse analysis; other variables relating to transactional distance; developing a prototype; and future…

Describes a laboratory study that examined the extent to which group gender composition affected group brainstorming performance in a computerized group support system (GSS) environment. Theory and research related to group gender composition and GSS is reviewed, and results indicate that gender composition did not affect group brainstorming…

Demonstrates the use of the well-known Bayes factor in the Bayesian literature for hypothesis testing and model comparison in general two-level structural equation models. Shows that the proposed method is flexible and can be applied to situations with a wide variety of nonnested models. (SLD)

Discusses the effects on healing of attitude, positive thinking, and affirmations. Presents a mathematical example of hypothesis testing. Results point to the desirability of discussing such ideas with students to emphasize that the use of hypothesis testing is not simply a mechanical procedure. (ASK)

Given the growth in scuba diving activities and the importance of environmental education programs to alleviate the potential impacts on coral reef ecosystems, there is a need to better understand the diving community, its environmental knowledge, and subsequent behavioral actions. The purpose of this study was to explore the role or influence of…

Rereading can improve the accuracy of people's predictions of future test performance for text material. This research investigated this rereading effect by evaluating 2 predictions from the levels-of-disruption hypothesis: (a) The rereading effect will occur when the criterion test measures comprehension of the text, and (b) the rereading effect…

We focus on the problem of ignoring statistical independence. A binomial experiment is used to determine whether judges could match, based on looks alone, dogs to their owners. The experimental design introduces dependencies such that the probability of a given judge correctly matching a dog and an owner changes from trial to trial. We show how…

The current investigation examined the form and magnitude of the relationship between political skill and two intrapersonal worker reactions--job satisfaction and job tension. Political skill was hypothesized to demonstrate an inverted U-shaped nonlinear relationship with job satisfaction and a U-shaped relationship with job tension. Data from…

In this study we investigated how alcohol consumption affects women's responses to unwanted sexual advances in a hypothetical dating situation. Sixty female social drinkers participated in a 2 times 2 between-subjects experiment, which examined the effects of moderate alcohol intoxication and relationship characteristics on behavioral responses to…

In this theoretical article, we take an exercise to be a collection of procedural questions or tasks. It can be useful to treat such an exercise as a single object, with individual questions seen as elements in a mathematically and pedagogically structured set. We use the notions of dimensions of possible variation and range of permissible change,…

This research examines the effect of achievement goals on performance attainment and the moderating role of performance contingencies. Results from 3 experiments strongly support the authors' hypotheses. Performance-avoidance goals undermined performance relative to performance-approach and mastery goals, regardless of contingency condition.…

This study extended research on prejudice against lesbian and gay (LG) persons by examining theoretically grounded links between intrapersonal and interpersonal manifestations of such prejudice. On the basis of G. A. Kelly's (1955/1991a, 1955/1991b) conceptualization of threat, the authors operationalized intrapersonal homophobia, or LG threat, as…

This paper comments on the response offered by Cheng and Novick to Luhmann and Ahn's initial comments on Cheng's and Cheng and Novick's previous articles. Cheng and Novick argue that people's willingness to generalize across contexts contradicts our hypothesis. They argue that previous studies demonstrate that participants generalize their…
