Applications of the theory of meaningfulness to psychology

The theory of meaningfulness of statements using numerical scales is summarized. Applications of this theory are surveyed. These deal with average performance, importance ratings, statistical tests, indices of consumer confidence, psychophysical scaling, block modeling of social structure, structural modeling in decision making, and the analysis of order and matching experiments.     

BARROW AND TIPLER'S ANTHROPIC COSMOLOGICAL PRINCIPLE

Abstract. John D. Barrow and Frank J. Tipler's recently published Anthropic Cosmological Principle is an encyclopedic defense of melioristic evolutionary cosmology. They review the history of the idea from ancient times to the present, and defend both a "weak" version, and two "strong" versions of the anthropic principle. I argue the weak version of the anthropic principle is true and important, but that neither of the two strong versions are well grounded in fact. Their "final" anthropic principle is a revision of Teilhard de Chardin's evolutionary cosmology. They rectify Teilhard's factual errors but commit even more serious psychological and religious errors of their own.     

The effects of student gender,race, and achievement on career exploration advice given by canadian preservice teachers

This study investigated the effects of gender, race, and achievement on ratings of appropriateness of occupations and classifications of occupations (people, data, things) suitable for future exploration by ninth-grade students. The subjects (N=125; 106 females, 19 males), advanced undergraduate education students, were each asked to evaluate a case folder in which gender (female, male, not stated), race (Native, non-Native), and achievement (higher average, lower average) were systematically varied. Subjects gave ratings of appropriateness for future exploration of occupations on 5-point Likert-type scales. The occupations rated also represented three classifications (data, people, things), yielding a second dependent variable. Analysis was accomplished using two four-way analyses of variance. The attribute most influencing ratings was achievement. However, the three-way interactions of gender, race, and achievement limit direct interpretation of the data, and suggest that complex combinations of student attributes influence teachers. The limitations of the present study are emphasized; the implications for advising young women and for future research are discussed.     

Extrinsic and Intrinsic Motivation to Use Computers in the Workplace1

Previous research indicates that perceived usefulness is a major determinant and predictor of intentions to use computers in the workplace. In contrast, the impact of enjoyment on usage intentions has not been examined. Two studies are reported concerning the relative effects of usefulness and enjoyment on intentions to use, and usage of, computers in the workplace. Usefulness had a strong effect on usage intentions in both Study 1, regarding word processing software (β=.68), and Study 2, regarding business graphics programs (β=.79). As hypothesized, enjoyment also had a significant effect on intentions in both studies, controlling for perceived usefulness (β=.16 and 0.15 for Studies 1 and 2, respectively). Study 1 found that intentions correlated 0.63 with system usage and that usefulness and enjoyment influenced usage behavior entirely indirectly through their effects on intentions. In both studies, a positive interaction between usefulness and enjoyment was observed. Together, usefulness and enjoyment explained 62% (Study 1) and 75% (Study 2) of the variance in usage intentions. Moreover, usefulness and enjoyment were found to mediate fully the effects on usage intentions of perceived output quality and perceived ease of use. As hypothesized, a measure of task importance moderated the effects of ease of use and output quality on usefulness but not on enjoyment. Several implications are drawn for how to design computer programs to be both more useful and more enjoyable in order to increase their acceptability among potential users.     

Occupational Wellness: The Integration of Career Identity and Personal Identity

Historically, career and vocational counseling have served as cornerstones to the counseling profession. Still, there are several survey studies that indicate that interest in career counseling among counseling professionals has eroded. Conversely, there has been an overwhelming response from counselors to the idea of wellness. The intent of this article is to encourage practicing counselors and researchers to consider career development as a key ingredient in the conceptualization of wellness. Furthermore, it is imperative that we begin to assist clients in achieving this aspect of occupational wellness through the integration of career identity and personal identity.     

Expectancy and stimulus frequency: A comparative analysis in rats and humans

We examined whether expectancy, one of several factors influencing attention, is similarly affected in rats and humans by manipulation of relative stimulus frequency, A two-choice reaction time (RT) task was developed for rats, and an analogous task was used for humans. Errors, RTs, discriminability, and response bias were measured. Both rats and humans shifted their response bias to the more frequent stimulus, with no change in overall discriminability. As stimulus probability or stimulus repetition increased, RTs and errors decreased. These results illustrate the similarity of expectancy in rats and humans. This two-choice RT task for rats can be used in future studies to examine the neuronal mechanisms of expectancy and attention.     

Governmental research funding and economic distortion

Science and technology are “good” things. Still, there are many good things that should not be done by government and there are many other things that the private sector does far better. Government-funded research and development (R&D) falls into both these categories. Research funding is big business. In 1998, the Department of Health and Human Services received $13.1 billion, the National Aeronautics & Space Administration $9.3 billion, the Department of Energy $5.6 billion, and the National Science Foundation $2.3 billion. Newt Gingrich, still adhering to the Progressive dictum that “government does it better,” is now calling for a doubling of current federal research expenditures. This article will assess the theoretical arguments for government-funded research and examine specific research programs of the Department of Energy and the Environmental Protection Agency. Throughout, I will argue that private property rights, the rule of law, and free markets are the greatest incentives to conduct scientific research; under-investment in R&D is due not to market failure but to the failure to have markets. a public interest group active in economic and environmental public policy issues.
