The Gender Gap on Wall Street: An Empirical Analysis of Confidence in Investment Decision Making

We attempted to identify the personal characteristics that influence confidence in an investment decision in an experiment administered to 1,359 subjects nationwide. Multiple regression was used to control statistically for variation among subjects and to develop a model of investment decision confidence. The most striking finding was that women had significantly lower confidence in an investment task than men, after controlling for all other relevant variables and characteristics including the amount of the investment decision itself. Familiarity with and present attitude about investing in the stock market, college credit hours in accounting and finance, experience in evaluating common stocks, the current level of the stock market, and the investment decision itself (the amount to be invested) were also found to be significant. Age, value of personal portfolio, years of college, and years of business experience were not significant characteristics.     

Does intra-individual change predict offender recidivism? Searching for the Holy Grail in assessing offender change

Offender rehabilitation effectively reduces recidivism for treatment groups compared to control groups, but there is less evidence demonstrating that intra-individual changes are related to reductions in risk. We review and critique academic and government literature linking individual change scores to recidivism, focusing on three key treatment domains: cognition, violence, and substance misuse. Database searches identified 378 studies measuring change, but only 53 studies yielding 49 explicit tests of the relationship between intra-individual change scores and recidivism outcome. Of the 49 available tests, 26 effect sizes (53.1%) were significant, ranging from small (d = 0.06) to large (d = 1.48). Across all domains, change variables significantly related to recidivism included known dynamic risk factors: antisocial attitudes, antisocial beliefs, antisocial associates, antisocial personality, social support, and substance misuse. Two additional findings centered on changes in negative emotion and successful treatment process. This review further suggests there is a need to utilize better measurement strategies and more sophisticated constructs. Additional practical, theoretical, and methodological implications are discussed.     

Cross-cultural generalizability of the Spiritual Transcendence Scale to the Philippines: Spirituality as a human universal

The Spiritual Transcendence Scale (STS) has been developed to operationalize spirituality as an intrinsic source of motivation that impels individuals to create a broad sense of personal meaning for their lives. Spiritual Transcendence is nondenominational in nature and hypothesized to underlie the development of religious sentiments. To further support the universal nature of Spiritual Transcendence, the STS was translated into a native Filipino language, Tagalog. Using two different, varied samples of Filipino adults (N?=?654 and 248, respectively), this study demonstrated that scores on the translated version evidenced acceptable levels of internal consistency, structural validity, and incremental validity over personality in predicting a wide range of psychosocial outcomes, like well-being and interpersonal style. Further analyses also indicated that the Tagalog version of the STS produced comparable means and standard deviations to its English counterpart. The data provided support for the hypothesis that spirituality is a robust, universal human quality because two languages that are etymologically distinct both include terms that describe transcendent experiences. The STS appears to be an empirically robust measure of these qualities that can be useful for researchers interested in establishing cross-cultural linkages in spiritual motivation.     

No Time of Day Modulation or Time Stamp on Multiple Memory Tasks in Rats

Various demonstrations of “time stamp” effects in the animal learning literature have reinforced the idea that circadian information is encoded as part of a combined internal/external representation of context and that this contextual information is utilized for complex retrieval processes supporting memory. The goal of the present series of experiments is to assess this idea by manipulating training/testing circadian times on a battery of learning and memory tasks commonly used in the rodent. The data obtained from five experiments using four different learning and memory paradigms provide no evidence for “time stamp” effects on place memory, context memory (aversive or appetitive), or S-R habit learning.     

John Wesley's Doctrine of Grace in Light of the Christian Tradition

This ecumenically minded article explores Wesley's understanding of grace both in its relation to experience – inward religion – and in relation to his doctrines of justification and sanctification. Wesley's treatments of justification and sanctification are compared to those of Luther, Calvin and Trent. His unique and ecumenical blending of traditions allowed Wesley to develop a doctrine of grace which offers significant resources to contemporary understandings of Christian life and practice.     

Effect sizes for experimenting psychologists.

This article describes three families of effect size estimators and their use in situations of general and specific interest to experimenting psychologists. The situations discussed include both between- and within-group (repeated measures) designs. Also described is the counternull statistic, which is useful in preventing common errors of interpretation in null hypothesis significance testing. The emphasis is on correlation (r-type) effect size indicators, but a wide variety of difference-type and ratio-type effect size estimators are also described.
