Qualitative differences between conscious and nonconscious processing? On inverse priming induced by masked arrows

In general, both consciously and unconsciously perceived stimuli facilitate responses to following similar stimuli. However, masked arrows delay responses to following arrows. This inverse priming has been ascribed to inhibition of premature motor activation, more recently even to special processing of nonconsciously perceived material. Here, inverse priming depended on particular masks, was insensitive to contextual requirements for increased inhibition, and was constant across response speeds. Putative signs of motor inhibition in the electroencephalogram may as well reflect activation of the opposite response. Consequently, rather than profiting from inhibition of primed responses, the alternative response is directly primed by perceptual interactions of primes and masks. Thus there is no need to assume separate pathways for nonconscious and conscious processing.     

What do I gain from joining crowds? Does self‐expansion help to explain the relationship between identity fusion,group efficacy and collective action?

Four studies were carried out to examine how identity fusion, self‐ and group efficacy, and collective action are related and what role self‐expansion plays in these relationships. In the pilot study, participants recalled their experience of participating in mass gatherings. The three other studies were conducted during mass gatherings organized for collective purposes: a music concert (Study 1), a bicycle activist event (Study 2), and Equality Days (Study 3). The results showed (a) a significant positive relationship between personal and group identity fusion, self‐expansion, and self‐efficacy (Study 1); (b) a significant mediating effect of self‐expansion on the relationship between personal and group identity fusion and group efficacy (Studies 1 and 2); and (c) a significant mediating effect of self‐ expansion and group efficacy on the relationship between identity fusion and collective action tendency (Studies 2 and 3).     

Paper and plastic in daily diary research: Comment on Green, Rafaeli, Bolger, Shrout, and Reis (2006)

The authors applaud A. S. Green, E. Rafaeli, N. Bolger, P. E. Shrout, and H. T. Reis's (2006) response to one-sided comparisons of paper versus electronic (plastic) diary methods and hope that it will stimulate more balanced considerations of the issues involved. The authors begin by highlighting areas of agreement and disagreement with Green et al. The authors review briefly the broader literature that has compared paper and plastic diaries, noting how recent comparisons have relied on study designs and methods that favor investigators' allegiances. The authors note some sorely needed data for the evaluation of the implications of paper versus plastic for the internal and external validity of research. To facilitate evaluation of the existing literature and assist in the design of future studies, the authors offer a balanced comparison of paper and electronic diary methods across a range of applications. Finally, the authors propose 2 study designs that offer fair comparisons of paper and plastic diary methods.     

Stress, Rewards, and Change in the Centrality of Women’s Family and Work Roles: Mastery as a Mediator

Although research suggests that stress and rewards experienced in a social role are associated with changes in the centrality (or personal importance) of that role over time, little attention has been given to the mechanisms that account for this relationship. This study was conducted to examine change in role mastery as a mediator in the relationship between changes in role experiences (stress and rewards) and changes in centrality among 195 women who simultaneously occupied the roles of parent care provider, mother, wife, and employee. Regression analyses indicated that increases in parent care, mother, and employee stress eroded mastery in those roles. In addition, increases in rewards were associated with a bolstered sense of mastery in each of the four roles. Mastery was found to be a mediating mechanism in the relationship between stress/rewards and centrality in one of the four roles examined, the employee role. However, changes in womens perceptions of mastery were unrelated to the extent to which women changed the importance of their three family roles. These findings extend prior research by demonstrating that mastery is a mechanism through which stress and rewards are associated with centrality in the employee role.     

The logic of questions as a theory of erotetic arguments

This paper argues for the idea that the logic of questions should focus its attention on the analysis of arguments in which questions play the role of conclusions. The relevant concepts of validity are discussed and the concept of the logic of questions of a semantically interpreted formalized language is introduced.This paper was presented at the symposium Erotetic Logic. A Dialogue organized by the Center for the Philosophy and History of Science of Boston University (February, 1994) and prepared during my stay at the Department of Philosophy, University of California, Riverside as a Fulbright grantee.I would like to thank Professors David Harrah and Sylvain Bromberger for valuable suggestions and comments.     

A new scale for use in non-clinical research into disinhibitive eating

The DIS, a 17-item questionnaire, was developed for subject selection in non-clinical research into disinhibitive eating. The DIS was designed to possess a tight and clear subscale structure, lessened impact of concern for dieting and explicit reference to self-esteem. Four subscales tapped the following themes: failed restriction, binge eating, weight fluctuations and self-esteem. DIS and the often used Restraint Scale (RS) were tested psychometrically among 269 female students from the Netherlands. Cronbach alpha was 0.88 for the DIS and 0.84 for the RS; correlation between the scales was 0.78. Factor analysis of the RS yielded the traditional two factors concern for dieting—weight fluctuations, whereas the DIS had a somewhat clearer four factors structure in accordance with its a priori subscales. On both the DIS and RS, high scorers were often currently dieting, and had higher Body Mass Index than low scorers. As to selection, DIS and RS differed in that partly different groups of individuals were selected when applying equally stringent cut-off scores. It was concluded that some of the psychometric and conceptual problems with the RS are alleviated by the DIS and that a next step is to behaviourally validate the DIS in disinhibition research.     

Formal reasoning in late adulthood: The role of semantic content and metacognitive strategy

Two experiments explored the availability of deductive or formal reasoning in late adulthood. In Experiment 1, fifty young (M=19.0 years) and 50 elderly adults (M=81.0 years) were assessed using adaptations of Wason's selection task and rated task content for familiarity, affect, and agreement. In Experiment 2, 100 young (M=21.0 years) and 100 elderly adults (M=81.0 years) were similarly assessed, with half of the subjects in each age group receiving a metacognitive strategy to facilitate reasoning. Results from Experiment 1 indicated equivalent reasoning among the groups on problems employed in earlier developmental research. In contrast, problems constructed to entail affect resulted in poorer performance by older adults. In Experiment 2, both young and older adults who used the metacognitive strategy reasoned equally acrossall problems. In both experiments, familiarity and agreement did not play a role in deductive reasoning performance, but affect seemed to be an interfering factor. Results are discussed in terms of competence-procedure and stability-decrement models of adult cognitive development.     

CATECHOLAMINE EXCRETION, PERFORMANCE, AND SUBJECTIVE STRESS

Psycho-endocrine relations were explored in 52 students exposed to moderately stressful psychological tests demanding selective attention. Subjects with high excretion rates of adrenaline performed better during the entire stress session than did subjects with low adrenaline excretion. The level of subjective stress increased consistently throughout the session in subjects with low excretion rates of adrenaline, while it remained relatively constant in subjects with high adrenaline excretion. No consistent relationship could be demonstrated between noradrenaline excretion and the psychological variables. Possible effects on the catecholamine-excretion patterns of factors such as severity and duration of the stress are discussed.
