The Utility of the Revised Life Orientation Test to Measure Optimism among Hong Kong Chinese

To examine the utility of the revised Life Orientation Test (LOT-R) to measure optimism among Hong Kong Chinese, the psychometric properties of the revised and the original versions of the Life Orientation Test were compared. A total of 248 Hong Kong Chinese undergraduates were studied in the fall and 165 of these participants were tested again 5 months later. Results indicated that the LOT-R is a reliable and valid measure of dispositional optimism among Hong Kong Chinese. Confirmatory factor analysis showed that the LOT-R represents a one-factor model of optimism better than does the original version. Despite its brevity, the LOT-R is psychometrically sounder than the original sclae. These findings point to the feasibility of replacing the original with the revised scale in future research among Hong Kong Chinese. However, the utility of the revised test in cross-cultural comparisons may still be limited by the absence of emic components. Further research on optimism in the Chinese people with the LOT-R should pay more attention to the identification of emic dimensions.     

“Theobiology”: Attempting to Understand God and Ourselves

Theobiology, describing the interface between theology and biology, is proposed as a means to help us in our attempt to understand God, God's world, and ourselves. This embodiment of theological knowledge includes the relationship of humans to plants and animals, to the environment or God's world of creation, to God. Humans experience through their bodies and bodily functions, their senses and perceptions, all knowledge, including theological, psychological, and sociological knowledge. Gender, perhaps the largest division in any species, is a very important issue in biology and in theobiology. The gender and attributes associated with God and Christ—those of the male—have alienated and disenfranchised female persons. A balance between flesh and spirit, the sacred and the secular, women and men is vital if we are to achieve a healthy life and to live as a loving Creator would want all to live—in love, peace, and harmony, with caring and mutual respect among all that make up life—plant, animal, environment, and God.     

Interchurch Couples: The Issue of Acceptance

Although the literature suggests that couples who belong to two different churches or denominations (interchurch marriages) may face lack of acceptance, there is practically no research on this issue. Based on a recent qualitative study, this article explores the ways in which interchurch couples struggle to gain acceptance. Also discussed are the attitudes or factors that relate to level of acceptance, as well as the strategies that interchurch couples utilize to deal with lack of acceptance.     

A critique of the Flynn Effect: massive IQ gains, methodological artifacts, or both?

The Flynn Effect proposed by Flynn (1984; 1987) is reviewed and evaluated. Even in the presence of a skeptical and critical scrutiny of the effect, it appears that there is more than just methodological artifact to be explained. But the acceptance of the effect has been too quick. The proper explanations for the effect will not be meaningful until the nature of the effect is much better understood than it is now. Six questions are raised that have not been adequately answered. Two criticisms of the logic underlying the Flynn Effect are presented — one showing that even if IQ and SAT are highly correlated, their secular means will not necessarily track one another; the second showing that results by Flynn, (1984) are as consistent with a changing IQ variance as with a changing mean. The second of these is empirically evaluated with a re-analysis of a subset of the sources of Flynn's original 1984 data. Finally, 10 research strategies and designs are suggested that would help us better understand the effect. The critique is developed with the goal of clarifying the nature, meaning and causes of the Flynn Effect. The author hopes that this critique will stimulate both healthy skepticism about the Flynn Effect and careful research into its actual causes.     

Never cross the path of a traveling salesman: The neural network generation of Halstead-Reitan trail making tests

The Halstead-Reitan Trail Making Test (TMT) is one of the most widely used neuropsychological instruments for the assessment of brain damage. Despite its usefulness, however, the TMT has two major disadvantages. It has not been constructed in a principled manner that would facilitate systematic investigation, and there is no established procedure for generating equivalent, but stochastically different, test forms. The reason is that the generation of self-avoiding TMT pathways resembles the finding of near-optimal solutions to the Euclidean Traveling Salesman Problem (TSP) and constitutes a computational problem that is NP-complete. This article describes a practical approach to the problem of generating stochastically different test forms. This approach employs anelastic net neural network to generate TMT forms based on self-avoiding, near-optimal paths, and closed circuits. The usefulness and limitations of this solution are discussed briefly in relation to alternative and complementary problems and procedures.     

Gender-Related Jokes in the Workplace: Sexual Humor or Sexual Harassment?1

When does a joke become sexual harassment? In a partial test of an integrative model of gender-related humor in the workplace, the role of personal and situational variables in perceptions of sexual harassment was examined. Other implications of sexual humor in the office were also studied.     

Differential inheritance of mental abilities in the Texas adoption project

Correlations on subscales of Wechsler IQ tests and the Revised Beta Examination were obtained for biologically related and unrelated individuals in 181 adoptive families in the Texas Adoption Project. Scores were also available for many of the birth mothers of the adopted children. In general, correlations were higher for biologically related individuals, suggesting the importance of genetic influences on intellectual abilities. To examine effects specific to subscales, an analysis of residualized subscale scores was carried out using the Revised Beta. After partialling out from each of the scales the variance predictable from the rest, a model was fit to family correlations among the residuals. Of the six Beta subscales, three showed specific genetic variance, two showed specific shared environmental variance, and one showed neither.     

Personality variables related to integrity test scores: The role of conscientiousness

Using a broad-based measure of normal personality, we tested the hypothesis that the trait conscientiousness is the best single predictor of scores on two well-researched integrity tests. Data from 180 traditional and nontraditional college students provided clear support for this hypothesis, but also indicated that a number of traits other than conscientiousness were likely to be related to integrity test scores. Scores on all six of the primary scales, and 33 of the 45 homogeneous item clusters (HICs) of the Hogan Personality Inventory were related to scores on the PDI Employment Inventory and/or the Personnel Selection Inventory. Personality variables were better predictors of scores on the PDI Employment inventory, which is a veiled-purpose (also referred to as personality based) test, than of scores on the Personnel Selection Inventory, which measures honesty-related attitudes and includes items calling for direct admissions of misdeeds.We are grateful for the assistance and cooperation of London House Inc., Personnel Decisions Inc., and Hogan Assessment Systems, Inc., and especially to Scott Martin, George Paajanen, and Joyce Hogan.
