Fractions We Cannot Ignore: The Nonsymbolic Ratio Congruity Effect

Although many researchers theorize that primitive numerosity processing abilities may lay the foundation for whole number concepts, other classes of numbers, like fractions, are sometimes assumed to be inaccessible to primitive architectures. This research presents evidence that the automatic processing of nonsymbolic magnitudes affects processing of symbolic fractions. Participants completed modified Stroop tasks in which they selected the larger of two symbolic fractions while the ratios of the fonts in which the fractions were printed and the overall sizes of the compared fractions were manipulated as irrelevant dimensions. Participants were slower and less accurate when nonsymbolic dimensions of printed fractions were incongruent with the symbolic comparison decision. Results indicated a robust basic sensitivity to nonsymbolic ratios that exceeds prior conceptions about the accessibility of fraction values. Results also indicated a congruity effect for overall fraction size, contrary to findings of prior research. These findings have implications for extending theory about the nature of human number sense and mathematical cognition more generally.     

Work social supports, role stressors, and work-family conflict: The moderating effect of age

The current study examined whether important distinctions are masked if participant age is ignored when modeling relationships among constructs associated with the work-family interface. An initial omnibus model of social support, work role stressors, and work-family conflict was tested. Multiple groups analyses were then conducted to investigate possible age differences in the patterns of relationships among these constructs for three age groups (28 and under, 29-45, and 46 and older). Several constructs in the model, including role stressors, social support, and work-family conflict, demonstrated mean level differences across the three age groups. Of greater significance, the relationships of some sources of social support and work-family conflict with other constructs in the model differed as a function of age group. Results suggest that conclusions drawn from the omnibus model take on a slightly different and more complicated meaning in the multiple groups analysis. These results have implications for how future research on the work-family interface should be conducted.     

« Contexte évaluatif,règles d’équité et d’égalité. Une approche stratégique de la justice distributive. »

This article must be considered within the framework of research on distributive justice in the organisational context (Adams, 1965; Deutsch, 1975; Colquitt and Jackson, 2002). The aim is to propose an analysis from a political point of view of the orientation towards equity and equality rules. We take as a starting point the model of political decision in the organisational context by Murphy and Cleveland (1995). The political approach postulates that one cannot pertinently give an account of the managers’ decision modes without locating them in their daily context of human relations management, and their management strategy. We will examine the links between the context of immediate management and the managers’ choices for equity or equality. The results of two studies will be presented. They tend to legitimate the relevance of this approach.     

Cognition at risk: Gestalt/feature-intensive processing and cigarette smoking in college students

Although previous research has shown the importance of feature-intensive processing of relevant information in the staving off of addictive behaviors, the present study examined the possibility that a more global, gestalt rejection of cigarette smoking may be operating to reduce smoking behavior. The present study addressed this possibility through the use of a decision efficacy rating procedure, in which smoking and nonsmoking respondents were asked to determine whether an individual was justified in smoking in a variety of given situations. Nonsmokers tended to reject smoking under any circumstances, whereas smokers tended to entertain mitigating circumstances more favorably in justifying smoking, especially when smoking could be construed as providing some perceived positive gains in serious situations. Results are discussed in terms of the gestalt/feature-intensive processing theory of cognition, and in terms of the importance of cognitive approaches to the understanding of addictive behaviors.     

Doing cognitive neuroscience: a third way

The “top-down” and “bottom-up” approaches have been thought to exhaust the possibilities for doing cognitive neuroscience. We argue that neither approach is likely to succeed in providing a theory that enables us to understand how cognition is achieved in biological creatures like ourselves. We consider a promising third way of doing cognitive neuroscience, what might be called the “neural dynamic systems” approach, that construes cognitive neuroscience as an autonomous explanatory endeavor, aiming to characterize in its own terms the states and processes responsible for brain-based cognition. We sketch the basic motivation for the approach, describe a particular version of the approach, so-called ‘Dynamic Causal Modeling’ (DCM), and consider a concrete example of DCM. This third way, we argue, has the potential to avoid the problems that afflict the other two approaches.     

When bonuses backfire: an inaction inertia analysis of procrastination induced by a missed opportunity

An inaction inertia analysis of procrastination was used to generate the prediction that using bonuses to encourage early task completion will have two opposing effects, encouraging early task completion by some but also inducing procrastination for those who miss the bonus. Study 1 showed that the addition of bonuses for early completion produced both of these effects and also led to overall task completion rates that were either equal to (large bonus) or actually less than (medium and small bonuses) those obtained by simply establishing a completion deadline with no bonus. In Study 2, a lottery methodology was used to manipulate the size of a missed bonus for all participants. Even under these conditions of reduced personal responsibility the larger missed bonus led to increased procrastination as predicted by the inaction inertia analysis. Possible mediating processes based on anticipated regret and perceived fairness were discussed. Copyright © 2007 John Wiley & Sons, Ltd.     

A neural marker of content-specific active ignoring

The ability to attend to relevant events and to ignore irrelevant stimuli is crucial to survival. Theories disagree on whether this ability is dependent solely on increased neural activation for relevant items or whether active ignoring can also play a role. The authors examined the active ignoring of stimuli using a preview search procedure, where irrelevant faces appeared prior to relevant house stimuli. They found increased activation in brain regions associated with spatial memory and in content-specific face-processing areas when participants ignored the irrelevant faces. Differences arose even on trials when only previewed faces appeared, and the magnitude of these differences predicted how well faces were ignored in search. Activation associated with active ignoring decreased when a secondary task was imposed during the preview. The data reveal a neural marker for the process of actively ignoring the content and locations of irrelevant stimuli.

When Is Believing “Seeing”? Hostile Attribution Bias as a Function of Self‐Reported Aggression1

Repeated exposure to adverse advents (e.g., risky driving) was thought to increase expectations for the recurrence of the event. Community‐based drivers (130 men, 133 women) were given scenarios depicting everyday road events that could be construed as benign, ambiguous, or malign by the degree of perceived provocation. Differences between levels of gender, ethnicity, age, aggressiveness, and provocation were measured by attributions of intent, hostility, and anger. Results showed that, overall, drivers accurately perceived provocation conditions. Hostile attributional biases were not evident among the sample as a whole, but were dependent on level of aggressiveness and provocation. Analysis of self‐reported driving behavior showed that young, aggressive majority group drivers who experience greater aggression on the road also were more likely to take more risks while driving. Controlling for miles driven, gender differences were not found.
