The conscious access hypothesis: origins and recent evidence

Consciousness might help to mobilize and integrate brain functions that are otherwise separate and independent. Evidence for this 'conscious access hypothesis' was described almost two decades ago, in a framework called global workspace theory. The theory had little impact at first, for three reasons: because consciousness was controversial; the evidence, though extensive, was indirect; and integrative theory was unfashionable. Recent neuroimaging evidence appears broadly to support the hypothesis, which has implications for perception, learning, working memory, voluntary control, attention and self systems in the brain.     

At the interface of social cognition and psychometrics: Manipulating the sex of the reference class modulates sex differences in personality traits

Psychometric surveys suggest that sex differences in personality are minimal. Herein, we argue that (a) the mind is likely biased toward assessing oneself relative to same-sex others, and (b) this bias may affect the measurement of sex differences in personality. In support of this, an experiment demonstrates modulation of sex differences on the HEXACO facets by manipulating the sex of the “reference class”—the group of people subjects compare themselves to when making self-assessments on survey items. Although patterns varied across traits, sex differences were relatively small in the “unspecified” and “same-sex” reference class conditions—but substantially larger in the “opposite-sex” condition. These findings point to a same-sex comparison bias that may impact the measurement of sex differences in personality.     

Schizotypy,cognitive performance,and genetic risk for schizophrenia in a non-clinical population

Schizophrenia risk alleles are expected to mediate effects on cognitive task performance, and aspects of personality including schizotypy, in nonclinical populations. We investigated how 32 of the best-validated schizophrenia risk alleles, singly and as summed genetic risk, were related to measures of schizotypal personality and measures of two aspects of cognitive performance, verbal skills (vocabulary) and visual-spatial skills (mental rotation), in healthy individuals. Summed genetic risk score was not associated with levels of total schizotypy or its three main subscales. Similarly, genotypic variation at none of the individual risk loci was related to cognitive performance measures, after correction for multiple tests. Higher overall genetic risk score was, however, associated with lower performance on the mental rotation test in males, with a broad set of loci contributing to this effect. These results imply that there is a lack of linear, genetically-based continuity connecting schizotypal cognition with the expression of schizophrenia itself, and indicate that, for males, higher genetic risk of schizophrenia exerts negative effects on visual-spatial skills, as measured by mental rotation.     

The Rorschach Index of Repressive Style and Scale Checking Style: A Study of Sex Differences

Males and females, subdivided into contrasting groups on the Rorschach Index of Repressive Style (RIRS), completed semantic differentials using themselves and their own art productions as the objects rated. Analysis was made of the relationship between sex and verbal style, and a scale checking style (use of end points versus use of intermediate points) believed to reflect a dimension of rapid, extreme decisions versus careful consideration of nuances. Results showed that males characterized by rich and fluid verbal processes tended toward cautious ratings (use of intermediate points) while females who were verbally free exhibited more extreme ratings (use of end points). It is concluded that a test variable may have different predictive significance in males and females, even though there is no sex difference in the magnitudes of the variables involved. There may be sex differences in the organization of cognitive processes.     

A Normative Study of TAT Ambiguity

Type D personality refers to a clustering of 2 stable personality traits, namely negative affectivity and social inhibition. Currently Type D is standardly assessed using the DS14. An experimental Type D personality scale, the DS⁽³⁾, was developed to examine an avenue for assessing Type D more efficiently. The DS⁽³⁾ differs from the DS14 in its use of a 3-point Likert scale to rate responses, use of all negatively worded items, and a rearranged presentation of items. This article examines the psychometric properties of this questionnaire by examining its dimensionality, item and scale properties, and cutoff scores to screen for Type D personality. Data from 2 clinical samples were analyzed using item response theory. The results suggest that the DS⁽³⁾ is a potentially suitable instrument for Type D assessment. It has high reliability, and Type D personality classification based on this scale corresponds well with the current standard Type D assessment based on the DS14.     

The Causes and Treatment of Backwardness by Cyril Burt

In this paper, self psychology is presented as a particular form of object-relations theory which directs the therapist to consider interactions within the group in the light of their effect on the sense of self of the individual. In traditional object-relations psychology the therapist works through defenses against the anxieties of expressing wishes for unacceptable forms of object-relations in the group, which are related to unconsciously warded off instinctual drives. In contrast, the therapist who adopts the framework of self psychology works through defenses against anxieties associated with expressing developmentally phase-legitimate self object needs. Thus, the individual's frustrated reactions to others are not interpreted as distorted and/or maladaptive, but as understandable reactions to the patient's experience of thwarted developmental needs for selfobject responsiveness which are repeated in the here-and-now interactions within the group. The selfobject transferences are described as well as the ways in which they may come into conflict with one another. Two clinical examples previously understood by the author from within a traditional object-relations framework are reviewed, and discussed from the perspective of self psychology.     

Information Context Structure and Risk Assessment

Abstract

Assessment of probabilistic values which comprise multidimensional attributes (e.g. risk) involves complex cognitive processes. This study explores the degree to which three informational context variables (nature of information, presentational conditions, and context structure), allocated according to a factorial design, affect risk assessment. The risk situation is represented by alarm over a potentially toxic cloud stagnating above a town, and is rated from 1 (negligible) to 10 (lethal) by subjects randomly assigned to one of the eight experimental modalities. Ratings are then processed by analysis of variance. Significant effect is found for the first variable (concrete information gives rise to significantly higher ratings than abstract information) and the second variable (sequential presentation leads to higher ratings), but the third variable would appear to have less functional impact. These results are discussed in the general framework of behavioural theories of decision-making, stressing the relevance of certain concepts and cognitive processes involved in risk assessment.     

Affective Priming Effects in the Left and Right Cerebral Hemispheres in Patients With Alzheimer's Disease

Alzheimer’s disease (AD) patients and control subjects were tested in an affective priming paradigm associated with an affective discrimination task. Two pictures, one affectively positive or affectively negative and the other neutral, were presented simultaneously in the right and in the left visual fields; the participants had to decide which of the two pictures was the most affectively positive or negative. The target pictures were preceded by a prime picture that was either affectively positive, affectively negative, or neutral. The principal result was the observation, in AD patients as well as in control subjects, of negative affective priming effects for targets presented in the right hemisphere, and of positive affective priming effects for targets presented in the left hemisphere. The presence of affective priming effects suggests that AD patients have no particular deficit in the automatic activation of emotional information; the fact that priming effects were also observed for targets presented in the left hemisphere showed that AD patients probably have no left hemisphere deficit in the automatic activation of emotional information. However, in AD patients, affective priming effects were significant with negative targets but not with positive targets, which could suggest that AD patients processed positive targets in a more semantic way than negative targets.     

Personality and Creativity: The Dual Pathway to Creativity Model and a Research Agenda

To better understand the relation between personality traits and creativity, we invoke the Dual‐Pathway to Creativity model (DPCM) that identifies two pathways to creative outcomes: (1) flexible processing of information (cognitive flexibility) and (2) persistent probing, and systematically and incrementally combining elements and possibilities (cognitive persistence). DPCM further proposes that dispositional or situational variables may influence creativity through either their effects on flexibility or persistence. Here, we propose the idea that approach‐related traits (e.g., openness to experience, extraversion, positive affectivity, and power‐motivation) may lead to greater creativity because they link to enhanced cognitive flexibility, whereas avoidance‐related traits (e.g., negative affectivity and neuroticism) under the right circumstances may lead to greater creativity because they link to enhanced cognitive persistence. Empirical support for this proposition is discussed, and a research agenda for future work on personality and creativity is set.
