How general across inventories is a general factor of personality?

Two recent analyses addressing the generality of a general factor of personality (GFP) across different personality inventories came to markedly different conclusions. By applying the methods used by the one that found a GFP to the data used by the one that did not, it was shown that a substantial GFP could be obtained in the latter case. It was also shown that similar GFPs could be derived from sets of more broadly or more narrowly defined questionnaire scales, or from self- and others’ reports on a given inventory. Finally, it was shown that a GFP defined from eight personality inventories showed a modest degree of correlation with criterion variables such as ratings by others and act-frequency clusters.     

What might a non-confessional theory of Catholic education look like?

This article emulates the new stance of Professor Michael Hand on faith schools. He illustrates how theological criteria could be used to inform and guide curriculum aims in a way that avoids indoctrination and the perils of faith-based education. This approach is adopted vis-à-vis Catholic education in order to sketch out what a non-confessional theory of Catholic education might look like. It is argued that a central feature of Catholic theology, as presented by the leading theologian Karl Rahner, is a recognition of the centrality of mystery in human existence. This theological insight is applied to the curriculum and it is used to provide a theological justification for a non-confessional account of Catholic education.     

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.     

The general factor of personality: Substance or artefact?

While it is now widely recognized that a general factor (GFP) can be extracted from most personality data, this finding has been subject to numerous critiques: (1) that the GFP is an artefact due to socially desirable responding; (2) that it is factorially indeterminate; (3) that it can be more parsimoniously modelled using blended variables; (4) that it shows less genetic variance due to dominance than should be true of a fitness trait; (5) that it correlates more weakly with g than would be predicted from Life History theory; (6) that it cannot be recovered across personality inventories. We present new evidence and argument to show that each of these critiques is open to reasonable doubt.

What might philosophy of science look like if chemists built it?

Had more philosophers of science come from chemistry, their thinking would have been different. I begin by looking at a typical chemical paper, in which making something is the leitmotif, and conjecture/refutation is pretty much irrelevant. What in fact might have been, might be, different? The realism of chemists is reinforced by their remarkable ability to transform matter; they buy into reductionism where it serves them, but make no real use of it. Incommensurability is taken without a blink, and actually serves. The preeminence of synthesis in chemistry could have led philosophers of science to take more seriously questions of aesthetics within science, and to find a place in aesthetics for utility. The necessary motion twixt macroscopic and microscopic views of matter in modern chemistry leads to the coexistence of symbolic and iconic representations. And in another way to the deliberate, creative violation of categories.     

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.     

Is there a general factor of preference for complexity?

It has been assumed that preferences for different aspects of complexity in visual patterns are intercorrelated. Evidence purporting to demonstrate this was examined and found to be inconclusive. The preferences of 111 Ss using three sets of patterns showed no correlation between preference for asymmetry, for multiplicity, and for heterogeneity of elements.     

What's in a look?

The most common behavioral technique used to study infant perception, cognition, language, and social development is some variant of looking time. Since its inception as a reliable method in the late 1950s, a tremendous increase in knowledge about infant competencies has been gained by inferences made from measures of looking time. Here we examine the logic, utility, and future prospects for further gains in our understanding of infant cognition from the use of looking time measures.     

Do targets of workplace bullying portray a general victim personality profile?

The aim of this study is to examine differences in personality between a group of bullied victims and a non-bullied group. The 144 participants, comprising of 72 victims and a matched contrast group of 72 respondents, completed Goldberg's (1999) International Personality Item Pool (IPIP). Significant differences emerged between victims and non-victims on four out of five personality dimensions. Victims tended to be more neurotic and less agreeable, conscientious and extravert than non-victims. However, a cluster analysis revealed that the victim sample can be divided into two personality groups. One cluster, which comprised 64% of the victim sample, do not differ from non-victims as far as personality is concerned. Hence, the results indicate that there is no such thing as a general victim personality profile. However, a small cluster of victims tended to be less extrovert, less agreeable, less conscientious, and less open to experience but more emotional unstable than victims in the major cluster and the control group. Further, both clusters of victims scored higher than non-victims on emotional instability, indicating that personality should not be neglected as being a factor in understanding the bullying phenomenon.     

Is there really a single factor of personality? A multirater approach to the apex of personality

A GFP is controversially debated on regarding the hierarchical structure of personality. Apart from theoretical argumentations, support for the existence of such a factor calls on the intercorrelations repeatedly found between personality domains. The current study used a data set containing one self-rating and two peer-ratings in order to replicate recent methodological approaches in modeling the GFP but also to apply a specific multirater approach able to disentangle method biases and to correct for nested data structure. Results did show the emergence of a GFP when modeled only with peer- or self-ratings, but did not support the idea of a GFP when modeled with multirater nested data. Findings are discussed including an interpretation of the GFP as successful impression management.     

Maternal personality and injury in children: is stability a protective factor?

Measures of injury were obtained in a birth cohort of 953 children in Wales along with maternal Eysenck Personality Inventory (EPI) and children's Behaviour Screening Questionnaire (BSQ) data. While there was no relationship between maternal E and child injury, children of low-N mothers had significantly fewer injuries than those of medium of high-N mothers. The magnitude of this trend remained after controlling for the BSQ variables also relating to injury, but was no longer significant in the case of management disorder or of sex. Moreover, while the association was observed for families with only one or two children, this was not the case for families with three or more children.     

What is unconsciousness in a fly or a worm? A review of general anesthesia in different animal models

All animals are rendered unresponsive by general anesthetics. In humans, this is observed as a succession of endpoints from memory loss to unconsciousness to immobility. Across animals, anesthesia endpoints such as loss of responsiveness or immobility appear to require significantly different drug concentrations. A closer examination in key model organisms such as the mouse, fly, or the worm, uncovers a trend: more complex behaviors, either requiring several sub-behaviors, or multiple neural circuits working together, are more sensitive to volatile general anesthetics. This trend is also evident when measuring neural correlates of general anesthesia. Here, we review this complexity hypothesis in humans and model organisms, and attempt to reconcile these findings with the more recent view that general anesthetics potentiate endogenous sleep pathways in most animals. Finally, we propose a presynaptic mechanism, and thus an explanation for how these drugs might compromise a succession of brain functions of increasing complexity.     

What is personality? Two myths and a definition

This article addresses the longstanding problem that the field of personality psychology remains in need of a consensus formulation of its core subject matter, that of the nature of “personality” itself. Part 1 of the article presents some reminders about the traditional pre-empirical status of concepts in science. Part 2 introduces and calls into question two widely accepted but nonetheless questionable propositions about the nature of personality: (a) that the term refers to an underlying causal entity within a person, and (b) that the study of personality is the study of the whole person. Part 3 presents a definition of “personality”, discussion elaborating and clarifying this definition, and an explication of the ways in which it differs from previous definitions. Part 4 discusses some benefits that accrue both to having a consensus definition in general, and to acceptance of the present definition in particular.     

Why does a mirror image look left-right reversed? A hypothesis of multiple processes

This paper proposes a solution to the mirror reversal problem: Why does a mirror reverse left and right but not up and down? The paper first reviews past hypotheses and shows that none of them has succeeded in explaining all the related phenomena. It then proposes a multiprocess hypothesis based on the insight that what is called a mirror reversal is actually composed of three different types of reversal: The Type I reversal is produced by the discrepancy between an orientational framework that is aligned with a viewer’s body and the one that is assumed in the viewer’s mirror image; the Type II reversal is produced by the discrepancy between the mental representation of an object and its mirror image; and the Type III reversal is produced by a mirror’s optical transformation. The proposed hypothesis is shown to provide reasonable accounts for all the related phenomena disputed in the past literature.     

The robustness of the factor structure of the Self-Restraint Scale: What does self-restraint encompass?

In contrast with the original version of the Self-Restraint Scale (SRS; [Weinberger, D.A., & Schwartz, G.E. (1990). Distress and restraint as superordinate dimensions of self-reported adjustment: A typological perspective. Journal of Personality, 58, 381–417]), confirmatory factor analysis did not support a four-factor solution. In the current study an exploratory factor analysis revealed a three-factor structure. Although the original subscales suppression of aggression, consideration of others, and impulse control were confirmed by the data, responsibility did not fit within the overall concept of self-restraint. These results provide some indication that although the subscales can be used independently, the way self-restraint is conceptualized should be reconsidered. Future studies are needed to confirm the factor structure observed in the current study.
