J.P. Rushton’s contributions to the study of altruism

This essay describes Rushton’s work on altruism over the past 40 years. During his academic career, he changed his theoretical approach from social learning theory to trait theory to sociobiology. My essay includes five sections. The first gives an overview of Rushton’s work on altruism. The second reviews his early work based on social learning theory. His laboratory and naturalistic experiments led him to conclude that altruism could be increased by exposure to models exemplifying the behavior, and that, once engaged in, the behavior could be durable over months and generalizable across situations. The third section discusses his work on the genetic foundation of altruism with social biology including his twin studies of prosocial behaviors using different age groups of both western and Asian samples. He concluded that about 50% of the variance in prosocial behaviors is heritable. The fourth section will describe altruism as part of the general factor of personality, the apex of the personality hierarchy. The last section summarizes my review of Rushton’s work on altruism.     

The general factor of personality: What lies beyond?—II

What remains of the covariance of personality traits after a general factor of personality (GFP) is removed? An earlier analysis based on a US adult community sample was extended to five additional samples, ranging from 739 to 2914 late-adolescent or adult individuals who had completed various personality questionnaires in twin and adoption studies. For the most part, the GFPs were similar. Most of the data sets revealed an additional Conscientiousness/conformity factor, but beyond that there was considerable variation across samples in the supplemental factors obtained.     

Between you and God,where is the general factor of personality? Exploring personality-religion relationships in a Muslim context

Personality-religiosity links were studied in a Muslim population. Agreeableness and Conscientiousness were generally the strongest correlates of religiousness. Evidence for the general factor of personality (GFP) was found in analyses of correlations among scores on the Big Five, in four studies (total N = 1000). Also, a GFP was positively correlated with gratitude to God, interest in religion, intrinsic religiosity and extrinsic-personal religiosity, but not extrinsic-social religiosity. Results demonstrated cross-cultural consistency of the GFP, and its relationship with a variety of religious constructs.     

The basic components of adult playfulness and their relation with personality: The hierarchical factor structure of seventeen instruments

The primary aim of this study was testing the structure of adult playfulness in a joint analysis of seventeen questionnaires and testing the relation of the factors with the big five personality traits. A sample of 244 adults completed the questionnaires and a five factor-solution fit the data best; i.e., (a) Humorousness; (b) Cheerfulness–Uninhibitedness; (c) Expressiveness; (d) Other-directedness; and (e) Intellectuality–Creativity. Correlation analyses (bivariate, canonical) and regression analyses indicated strong overlap of the broader personality factors and the Cheerfulness–Uninhibitedness-factor (extraversion and emotional stability) as well as the Expressiveness-factor (extraversion). The study contributes towards a better understanding of the structure of playfulness in questionnaires developed for adults. Implications for future research are discussed.     

Spearman’s Law of Diminishing Returns and national ability

This research examined Spearman’s Law of Diminishing Returns (SLODR) using national ability as the unit of analysis. National ability was estimated using international standardized tests such as the Programme for International Student Assessment (PISA), Trends in International Mathematics and Science Study (TIMSS), and Progress in International Reading Literacy Study (PIRLS). Factor analysis estimated the national G loadings of tests for high and low ability nations. Consistent with SLODR, the G loadings of tests were lower for higher ability nations. The pattern was confirmed after correcting for school attendance and age biases. Because a test’s g loading is directly related to its predictive validity (correlation with outcomes), our results imply that the predictive validity of tests may be lower for higher ability nations.     

Confirmatory Factor Analysis of the Childhood Anxiety Sensitivity Index: A Gender Comparison

The Childhood Anxiety Sensitivity Index (CASI) is an 18-item self-report tool designed to measure the construct of anxiety sensitivity (i.e. the belief that anxiety may have harmful consequences such as sickness, embarrassment, or loss of control) in children and adolescents. Previous factor analytic examinations of the CASI have produced varied results. Gender may play a role in this observed variability. In an effort to confirm the factor structure of the measure across gender, CASI items for 671 children and adolescents were subjected to confirmatory factor analysis. Results indicated that for boys two-, three-, and four-factor structures provided a relatively good fit to the data, with the three-factor structure emerging as having the best fit overall. In contrast, for girls only the three-factor structure fitted the data well. Direct comparison of fit of the three-factor model across gender provided evidence to support the notion that childhood anxiety sensitivity is similar in structure across gender.     

Five Facets Mindfulness Questionnaire—Reliability and Factor Structure: A Swedish Version

Two studies were conducted to assess the Swedish version of the Five Facets Mindfulness Questionnaire (FFMQ), which was originally created by Baer et al. (2006). The aim of Study 1 was to examine the psychometric properties of the FFMQ using data from 495 individuals. Quantitative and qualitative analyses resulted in a reduction of the scale by 10 items. Psychometric properties, including internal consistency of the revised instrument, were examined. The Swedish FFMQ provides results comparable to those obtained by Baer. Cronbach's alphas were high for all the facets. The Swedish FFMQ appears to be a potentially useful tool in measuring mindfulness among Swedish participants. The aim of Study 2 was to test the suggested hierarchical five-factor solution and construct validity, using a confirmatory factor analysis (CFA). Similar to findings for the English version of the FFMQ, the CFA showed that the Observing facet was not a significant part of an overall self-reported mindfulness structure in a Swedish population with little meditation experience.     

Virtue or Art?: Political Friendship Reconsidered

In Talking to Strangers (2004), Danielle Allen argues that democratic citizens will need to acquire new habits for contending with distrust in order to prolong the democratic experiment. Though Allen's solution recalls her reading of the Republic, it is to Aristotle, not Plato, that she turns for help theorizing those habits. Drawing upon the Nicomachean Ethics, she proposes arts or techniques that might substitute for and outpace justice by enabling democratic strangers to treat one another like friends. While I endorse Allen's analysis of the problems posed by rising levels of distrust, I propose a different solution. First, I argue that the habits Allen describes would have to be virtues and not merely techniques in order to effect real political change. Then, second, I identify those habits as “piety” and “gratitude”—virtues which, I contend, are not so much substitutes for as supplements to justice. My argument thus elaborates Thomas Aquinas's account of justice and its “potential parts” in the Summa Theologiae.     

MARGARET THATCHER'S CHRISTIAN FAITH: A Case Study in Political Theology

Throughout the 1980s Margaret Thatcher dominated British and global politics. At the same time she maintained an active Christian faith, which she understood as shaping and informing her political choices and policies. In this article I argue that we can construct from Thatcher's key speeches, her memoirs, and her book on public policy a cultural “theo‐political” identity which guided her political decisions. Thatcher's identity was as an Anglo‐Saxon Nonconformist. This consisted of her belief in values such as thrift and hard work, care for the family and local neighbor, and charitable generosity; her belief in the renewal of the national British Christian spirit; and her notion of morality as the opportunity for free choice. Without a recognition of the centrality of her theo‐political identity, it is difficult to understand the values and beliefs which were central to her political life. The methodological issues raised by the construction of this theo‐political identity are examined in this article. The aim of the proposed methodology is to develop theological insights into a political phenomenon like Thatcher rather than make policy judgments or recommendations.     

The cross-lagged relationship between interpersonal forgiveness and depression symptoms in China

This study investigated the relationship between the process of forgiveness and depressive symptoms in China. A total of 116 college students who had experienced an interpersonal transgression “within the past week” were selected to perform the tracking measurements at 2-week intervals. Cross-lagged models showed that the victim's depressive symptoms were related to increasing revenge and avoidance motivations as well as decreased benevolence motivation; however, the revenge, avoidance, and benevolence motivations of the victims did not predict subsequent changes in depressive symptoms. These results confirm that the presence of depressive symptoms is a predictor of the reduced interpersonal forgiveness, and the alleviation of individuals' depressive symptoms plays a protective role in the adaptive process of interpersonal relationships.
