    In dit onderzoek wordt onderzocht of de negatieve reacties op morele weigeraars voortkomen uit de weigering, of uit de morele gronden voor deze weigering. Bovendien wordt onderzocht of deze negatieve reacties vooral optreden bij mensen met een sterke morele identiteit en of lichamelijke reiniging de bedreigde identiteit kan herstellen. Participanten (N = 110) werden gevraagd om een stuk worst te proeven, wasten al dan niet hun handen en werden geconfronteerd met een weigeraar die de worst niet had gegeten vanuit morele of niet-morele redenen. Resultaten zijn in overeenstemming met de verwachtingen en laten zien dat mensen zich meer bedreigd voelen door morele weigeraars dan niet-morele weigeraars en dat dit speciaal geldt voor mensen met een sterke morele identiteit. Wanneer participanten echter hun handen hebben gewassen verdwijnt dit negatieve effect van morele weigeraars op het zelfbeeld

    The combinatorics of the Baer-Specker group

    Full text link
    Denote the integers by Z and the positive integers by N. The groups Z^k (k a natural number) are discrete, and the classification up to isomorphism of their (topological) subgroups is trivial. But already for the countably infinite power Z^N of Z, the situation is different. Here the product topology is nontrivial, and the subgroups of Z^N make a rich source of examples of non-isomorphic topological groups. Z^N is the Baer-Specker group. We study subgroups of the Baer-Specker group which possess group theoretic properties analogous to properties introduced by Menger (1924), Hurewicz (1925), Rothberger (1938), and Scheepers (1996). The studied properties were introduced independently by Ko\v{c}inac and Okunev. We obtain purely combinatorial characterizations of these properties, and combine them with other techniques to solve several questions of Babinkostova, Ko\v{c}inac, and Scheepers.Comment: To appear in IJ

    How effortful is cognitive control? Insights from a novel method measuring single-trial evoked beta-adrenergic cardiac reactivity

    The ability to adjust attentional focus to varying levels of task demands depends on the adaptive recruitment of cognitive control processes. The present study investigated for the first time whether the mobilization of cognitive control during response-conflict trials in a flanker task is associated with effort-related sympathetic activity as measured by changes in the RZinterval at a single-trial level, thus providing an alternative to the pre-ejection period (PEP) which can only be reliably measured in ensemble-averaged data. We predicted that response conflict leads to a physiological orienting response (i.e. heart rate slowing) and increases in effort as reflected by changes in myocardial beta-adrenergic activity (i.e. decreased RZ interval). Our results indeed showed that response conflict led to cardiac deceleration and decreased RZ interval. However, the temporal overlap of the observed heart rate and RZ interval changes suggests that the effect on the latter reflects a change in cardiac pre-load (Frank-Starling mechanism). Our study was thus unable to provide evidence for the expected link between cognitive control and cardiovascular effort. However, it demonstrated that our single-trial analysis enables the assessment of transient changes in cardiac sympathetic activity, thus providing a promising tool for future studies that aim to investigate effort at a single-trial level

    The (Non-)Effect of Unemployment Benefits:Variations in the effect of unemployment on life-satisfaction between EU countries

    A negative effect of unemployment on subjective well-being has been demonstrated in many studies casting substantial doubt about assumptions of decisions of individuals to choose unemployment voluntarily as the utility-maximising option. These studies have been extended to take into account national-level context factors which have been shown to moderate the relationship between unemployment and life-satisfaction. So far most studies focussed mainly on economic indicators, although demographic and cultural differences between countries also affect how unemployment is perceived. An important variable that is not included in the majority of proper multilevel studies is the extent of unemployment benefits. Traditional micro-economic approaches argue that more extensive provisions should reduce the cost of unemployment and therefore reduce the motivation to regain employment—reflected in a reduction of the negative impact of unemployment. This study investigates this claim by using European Values Study data from all European Union countries and Norway as well as harmonised macroeconomic statistics from Eurostat. It finds that the effect of unemployment on life-satisfaction is indeed moderated by economic and demographic national-level factors, but not by unemployment benefits. To what extent unemployment reduces life-satisfaction varies greatly between countries, but appears to not be influenced by the extent of state unemployment provisions

    Culture shapes how we look at faces

    Background: Face processing, amongst many basic visual skills, is thought to be invariant across all humans. From as early as 1965, studies of eye movements have consistently revealed a systematic triangular sequence of fixations over the eyes and the mouth, suggesting that faces elicit a universal, biologically-determined information extraction pattern. Methodology/Principal Findings: Here we monitored the eye movements of Western Caucasian and East Asian observers while they learned, recognized, and categorized by race Western Caucasian and East Asian faces. Western Caucasian observers reproduced a scattered triangular pattern of fixations for faces of both races and across tasks. Contrary to intuition, East Asian observers focused more on the central region of the face. Conclusions/Significance: These results demonstrate that face processing can no longer be considered as arising from a universal series of perceptual events. The strategy employed to extract visual information from faces differs across cultures
