Negative Numbers are not yet Automatically Associated with Space in 6th Graders

ABSTRACT

The metaphor of the mental number line accounts for numerous empirical effects of spatial-numerical associations. In the present study, we aimed at investigating directional spatial-numerical associations reflected by SNARC-like digit-direction and sign-direction congruency effects as well as the sign-digit compatibility effect when 6^th graders performed magnitude comparisons of multi-symbol numbers (i.e., positive and negative numbers). As spatial-numerical associations were associated with sensorimotor experiences, we used whole-body and finger tapping responses to manipulate the extent of motor responses. We only observed a SNARC-like digit-direction congruency effect, but neither a sign-direction congruency nor a sign-digit compatibility effect. This indicates that 6^th graders may already have developed spatial-numerical associations for absolute number magnitude, but not yet for polarity signs. Furthermore, not observing a sign-digit compatibility effect seemed to suggest that 6^th graders may not yet process multi-symbol numbers in the same parallel componential way as adults do. We argue that while 6^th graders are able to process negative numbers, they are not yet automatically associated with space or integrated in the place-value structure of the Arabic number system like multi-digit numbers are at this age.     

The nature of stress experienced by lesbians and gay men

Abstract

This study examined both the meanings and sources/causes of stress from the perspectives of lesbians and gay men (n=30), using a series of focus groups. The findings suggest that stress is considered a part of life itself, and is perceived to contain both negative (e.g. detrimental effects on health and overall functioning, unfairness, out-of-control), and positive (e.g. a motivator, growth-facilitator) elements. The sources/causes of stress (i.e. stressors) identified include stress experienced from the “coming out” process, stress in family relations and intimate relationships, conflict over one's sexuality given society's homophobic and heterosexist attitudes toward lesbians and gay men, as well as stress from financial and work-related issues. More importantly, this study suggests that culture/ethnicity, gender, and aging, which are interconnected with one's sexual identity, play an important role in shaping the experiences of stress among lesbians and gay men.     

Recidivism and dependency in a psychiatric population: An investigation with kelly's dependency grid

Over the years there have been varied attempts to explain or predict recidivism, which is a phenomenon whereby psychiatric patients are hospitalized repeatedly. Recent efforts to predict relapse have used specific symptoms (Harris, Bergman, & Bachrach, 1986), diagnoses (Kastrup, 1987; Lally, 1989), postdischarge treatment compliance (Caton, Koh, Fleiss, Barrow, & Goldstein, 1985), and the level of emotional expression in the family environment (Doane, Goldstein, Miklowitz, & Falloon, 1986) as relapse predictors. Despite progress, many unanswered questions remain. The present study examined recidivism from the perspective of personal construct psychology (Kelly, 1955). The Dependency Grid was administered to 33 first-admission patients, 39 recidivists, and 26 controls. As hypothesized, recidivists identified the smallest social network and the fewest people on whom they believed they actually could rely in a crisis. In contrast, patients experiencing their first admission offered an extensive array of individuals to whom they felt they could turn in a crisis. Controls reported the greatest number of social resources potentially available to them, but then selectively chose a sample of them as individuals on whom they would be comfortable relying. Results are discussed in terms of support for Kelly's personal construct theory.     

Categorical perception of morphed objects using a free-naming experiment

Morphed figures entail a dominant and nondominant interpretation. Testing perception of morphed objects using forced-choice methods demonstrates that morphed figures are perceived as their dominant interpretation (“categorical perception”, or CP). Using a more natural free-naming response could reveal whether CP is an effect independent of method. In Experiment 1, therefore, series of morphed figures were tested for CP using free naming. Half of the morph series were identified as CP patterns. In Experiment 2, we used forced choice to investigate CP, resulting in an increase of number of CP series compared to free naming. The overlap between CP series of Experiments 1 and 2 was small, however. Experiment 3 revealed that higher perceptual similarity between the extremes of the series was strongly related to CP for the free-naming method, in contrast to the forced-choice method. We conclude that the observation of CP depends on the intactness of the intrinsic object structure caused by the morphing procedure.     

Ageing faces in ageing minds: A review on the own-age bias in face recognition

Similar to the well-established own-race bias, participants are more accurate at remembering own- relative to other-age faces. An own-age bias (OAB) in face memory was demonstrated in participants older than approximately 5 years. Crucially, the OAB is modulated by contact—participants with substantial contact with other-age persons show either reduced or absent OAB effects. In line with a perceptual expertise account of the phenomenon, holistic processing of other-age faces is less efficient when tested with young adult versus child faces, and differential holistic processing may therefore reflect one mechanism contributing to the OAB. A possible additional contribution of sociocognitive factors to the OAB remains largely untested. Importantly, event-related brain potential studies suggest that the own-race and own-age biases are based on at least partly different mechanisms. Theoretical explanations for different group-based biases in face memory will need to consider these findings.     

Dynamics of psychological contracts with work engagement and turnover intention: The influence of organizational tenure

This study investigated the interrelations of the psychological contract with work engagement and turnover intention, which has hitherto been a largely overlooked topic in psychological contract research. Although previous research has mainly focused on how psychological contracts influence job attitudes and behaviours, it is proposed here that attitudes and behaviours also affect the psychological contract that the employee has with the organization. Moreover, it is proposed that because reciprocity norms are more important among shortly tenured employees, mutual relationships between psychological contracts and work engagement and turnover intention were stronger for employees with lower organizational tenure. Longitudinal data were collected among 240 employees and proposed models were evaluated with structural equation modelling. The results show that indeed psychological contract fulfilment was longitudinally related to higher work engagement and lower turnover intentions, but only for employees with low tenure. Moreover, stability in work engagement, turnover intention, and psychological contract over time was higher for those with high tenure, whereas the relations between turnover intention and the psychological contract were stronger for those with low organizational tenure. These findings demonstrate that psychological contracts are reciprocally interrelated with work outcomes, and that such relations are stronger for those with low tenure.     

Religious support and psychosocial well-being among a religious Jewish population

The three subscales of the Religious Support Scale assess perceived support from a person’s religious community, religious leaders, and God. This three-factor structure was replicated in the current study with a sample of 277 religious Jewish persons residing in Israel. Hierarchical canonical analysis showed that, even after controlling for general social support, Religious Leader and God Support were related to lower emotional distress, Religious Leader and Religious Community Support contributed to a higher level of life satisfaction, and Religious Community and God Support contributed to the prediction of perceived health. Findings are discussed in terms of religious support’s generalizability as a psychosocial resource for persons of various faiths.     

Practical Reason: A Review of the Current Debate and Problems

Abstract

In this review article I refer to some of the most relevant recent publications in the field of practical rationality, mainly drawing on two new anthologies by Wallace and Millgram that contain the principal arguments in the current debate, and on new books and articles by Bittner, Dancy, Nida-Rümelin and Raz. The purpose of the article is to offer an overview of the relevant positions in the current debate, to clarify the main arguments against the belief-desire model, and to situate some of the problems - e.g. what counts as a reason - within the wider field of practical rationality as a whole - e.g. how to argue about practical reasoning from the point of view of our self-understanding as autonomous agents.
