The Numerical Stroop Effect in Primary School Children: A Comparison of Low,Normal, and High Achievers

Sixty-six primary school children were selected, of which 21 scored low on a standardized math achievement test, 23 were normal, and 22 high achievers. In a numerical Stroop experiment, children were asked to make numerical and physical size comparisons on digit pairs. The effects of congruity and numerical distance were determined. All children exhibited congruity and distance effects in the numerical comparison. In the physical comparison, children of all performance groups showed Stroop effects when the numerical distance between the digits was large but failed to show them when the distance was small. Numerical distance effects depended on the congruity condition, with a typical effect of distance in the congruent, and a reversed distance effect in the incongruent condition. Our results are hard to reconcile with theories that suggest that deficits in the automaticity of numerical processing can be related to differential math achievement levels. Immaturity in the precision of mappings between numbers and their numerical magnitudes might be better suited to explain the Stroop effects in children. However, as the results for the high achievers demonstrate, in addition to numerical processing capacity per se, domain-general functions might play a crucial role in Stroop performance, too.     

Role Satisfaction Mediates the Relation between Role Ambiguity and Social Loafing among Elite Women Handball Players

The aims of the study were to develop a questionnaire on self-reported social loafing (SRSLQ), and then to examine its relations with role ambiguity and role satisfaction in a sample of 110 women handball players competing at the elite level in Norway. Structural equation modeling analyses indicated that the SRSLQ was a psychometrically sound measure. In line with the expectations, role satisfaction fully mediated the positive relation between role ambiguity and self-reported social loafing: The more players experienced role ambiguity, the less satisfied they were with their role in the team, and the more social loafing they reported.     

What Mediates Links Between Age and Well-being? A Test of Social Support and Interpersonal Conflict as Potential Interpersonal Pathways

We examined potential nonlinear links between age and subjective well-being, and the interpersonal processes (i.e., support, conflict) responsible for such links. One hundred forty-four men and women between the ages of 30–70 completed measures of satisfaction with life, social support (interpersonal support evaluation list), and social negativity (test of negative social exchanges). Nonlinear regression analyses revealed a significant quadratic trend between age and satisfaction with life (SWL, p = .01) where age was associated with lower SWL in the young to middle-aged sample, but higher SWL in the middle-age to older adult sample. Analyses further revealed that interpersonal tensions statistically mediated the nonlinear links between age and SWL. These data suggest that negative interpersonal exchanges may be important contributors to well-being at midlife.     

Measuring consciousness: task accuracy and awareness as sigmoid functions of stimulus duration

When consciousness is examined using subjective ratings, the extent to which processing is conscious or unconscious is often estimated by calculating task performance at the subjective threshold or by calculating the correlation between accuracy and awareness. However, both these methods have certain limitations. In the present article, we propose describing task accuracy and awareness as functions of stimulus intensity (thus obtaining an accuracy and an awareness curve) as suggested by Koch and Preuschoff (2007). The estimated lag between the curves describes how much stimulus intensity must increase for awareness to change proportionally as much as accuracy and the slopes of the curves are used to assess how fast accuracy and awareness increases and whether awareness is dichotomous. The method is successfully employed to assess consciousness characteristics on data from four different awareness scales.     

Rehabilitation of reading in older individuals with macular degeneration: a review of effective training programs

Macular degeneration (MD) is the most common cause of visual impairment among older adults. It severely affects reading performance. People with MD have to rely on peripheral vision for reading. In this review, we considered several training programs that aim to improve peripheral reading, with a focus on eccentric viewing, oculomotor control, or perceptual learning. There was no strong support in favor of one particular training method for rehabilitation of reading in MD, but there is evidence that older individuals with MD can be trained to improve reading performance, even within limited time.     

Spontaneous goal inferences are often inferred faster than spontaneous trait inferences

We present four experiments in which participants were exposed to texts depicting behaviors that afforded inferences about actors' traits and goals. Results from a false recognition task with varying response deadlines revealed heightened activation of goal inferences already within a 350 ms response deadline. In contrast, trait inferences were made only when there was no response deadline, and when the behavior also implied a goal. These results indicate that spontaneous inferences on goals are often encoded more strongly in memory and are reactivated much more quickly in comparison with spontaneous trait inferences. Moreover, spontaneous trait inferences are often facilitated when an inference is first made on the goal of the behavior. These findings are discussed in light of recent developmental and neuroscientific evidence on social inferences, and current theories on impression formation.     

On the Duties of Commission in Commercial Life. A Kantian Criticism of Moral Institutionalism

In latter-day discussions on corporate morality, duties of commission are fiercely debated. Moral institutionalists argue that duties of commission—such as a duty of assistance—overstep the boundaries of moral duty owed by economic agents. “Moral institutionalism” is a newly coined term for a familiar position on market morality. It maintains that market morality ought to be restricted, excluding all duties of commission. Neo-Classical thinkers such as Baumol and Homann defend it most eloquently. They underpin their position with concerns that go to the core of liberalism—the dominant western political theory that sustains the ideals of both the free market and the free, rational person. Those authors claim that liberalism calls for a fully differentiated market because it resents the politicization of the market. Fully differentiated markets exclude duties of commission. They also claim that full differentiation of the market closes the troublesome gap between moral motivation and moral virtue. Full differentiation redeems the promise of “easy virtue”. In this paper moral institutionalism will be rejected from a Kantian point of view, mostly inspired by Herman’s thesis on the invisibility of morality. Liberalism may perhaps ban the politicization of the market; it does not forbid its moralization. The idea of a fully differentiated market must also be rejected because it is either morally over-demanding (to the morally autonomous person) or morally hazardous (to the person with failing moral motivation). Contrary to what the moral institutionalists claim, right action, morally, is actually quite difficult in fully differentiated markets.     

A comparison of two sex-role androgyny measures in a study of sex-role identity for incarcerated delinquent and nondelinquent females

A sample of 100 incarcerated delinquent females and 100 nondelinquent female matched for age and socioeconomic status were compared on three aspects of sex-role identity. The Bem Sex-Role Inventory and the PRF ANDRO scale were used to assess sex-role androgyny; the Traditional Family Ideology scale was used to assess sex-role attitudes; and several questions concerning heterosexual relationships were asked. Correspondence between the two androgyny measures was moderate at the interval level of measurement and poor at the nominal level. Repeat offenders were significantly higher than first-time offenders and nondelinquents on the BSRI masculine scale; a significantly higher percentage of repeat offenders were classified as androgynous by the BSRI. No differences were observed using the PRF ANDRO scales. Heterosexual relationships were more important in the lives of delinquent females on both friendship and helping dimensions.     

The validity of the Crites model of career maturity

To test the validity of the Crites model of career maturity, career maturity and noncareer maturity measures were administered to 312 ninth graders and to 200 technical college students. Scores on all measures were intercorrelated and factor analyzed. The results show that, as predicted, most of the Career Choice Competencies have more in common with each other than they have with Career Choice Attitudes; Career Choice Competencies are fairly highly positively related to each other; Career Choice Attitudes and Career Choice Competencies have more in common with each other in grade 9 than they do in the post-secondary grades; and there is a relationship between career maturity and sex and race of ninth graders and technical college students. The results do not support the hypothesized multidimensional structure of the Crites model or the hypothesis that variables in the Crites model have more in common with each other than they have with noncareer maturity variables. Discussion includes several possible explanations for failure to support the Crites model, and suggestions for further research.
