Children's activities and their meanings for parents: a mixed-methods study in six Western cultures

Theoretical perspectives and research in sociology, anthropology, sociolinguistics, and cultural psychology converge in recognizing the significance of children's time spent in various activities, especially in the family context. Knowing how children's time is deployed, however, only gives us a partial answer to how children acquire competence; the other part must take into account the culturally constructed meanings of activities, from the perspective of those who organize and direct children's daily lives. In this article, we report on a study of children's routine daily activities and on the meanings that parents attribute to them in six Western middle-class cultural communities located in Italy, The Netherlands, Poland, Spain, Sweden, and the United States (N = 183). Using week-long time diaries kept by parents, we first demonstrate similarities as well as significant differences in children's daily routines across the cultural samples. We then present brief vignettes--"a day in the life" --of children from each sample. Parent interviews were coded for themes in the meanings attributed to various activities. Excerpts from parent interviews, focusing on four major activities (meals, family time, play, school- or developmentally related activities), are presented to illustrate how cultural meanings and themes are woven into parents' organization and understanding of their children's daily lives. The results of this mixed-method approach provide a more reliable and nuanced picture of children's and families' daily lives than could be derived from either method alone.     

Illusory own body perceptions: Case reports and relevance for bodily self-consciousness

Neurological disorders of body representation have for a long time suggested the importance of multisensory processing of bodily signals for self-consciousness. One such group of disorders – illusory own body perceptions affecting the entire body – has been proposed to be especially relevant in this respect, based on neurological data as well as philosophical considerations. This has recently been tested experimentally in healthy subjects showing that integration of multisensory bodily signals from the entire body with respect to the three aspects: self-location, first-person perspective, and self-location, is crucial for bodily self-consciousness. Here we present clinical and neuroanatomical data of two neurological patients with paroxysmal disorders of full body representation in whom only one of these aspects, self-identification, was abnormal. We distinguish such disorders of global body representation from related but distinct disorders and discuss their relevance for the neurobiology of bodily self-consciousness.     

Large-Scale Assessment of Change in Student Achievement: Dutch Primary School Students’ Results on Written Division in 1997 and 2004 as an Example

This article discusses large-scale assessment of change in student achievement and takes the study by Hickendorff, Heiser, Van Putten, and Verhelst (2009) as an example. This study compared the achievement of students in the Netherlands in 1997 and 2004 on written division problems. Based on this comparison, they claim that there is a performance decline in this subdomain of mathematics, and that there is a move from applying the digit-based long division algorithm to a less accurate way of working without writing down anything. In our discussion of this study, we address methodological challenges that come in when investigating long-term trends in student achievements, such as the need for adequate operationalizations, the influence of the time of measurement and the necessity of the comparability of assessments, the effect of the assessment format, and the importance of inclusion relevant covariates in item response models. All these issues matter when assessing change in student achievement.     

More Difficult to Believe? Luther on Divine Omnipotence

This article considers Luther's statement in thesis 21 of the 1545 doctoral disputation of Petrus Hegemon (1545) concerning the difficulty of belief in creatio ex nihilo , and suggests that this difficulty shapes the later Luther's theology in significant ways. The difficulty is reconstructed as a gradual movement into the mystery of the creatio ex nihilo . The first site of difficulty correlates the knowledge of creatures as particulars with the knowledge of the Creator as the source of existence. The move towards a second site is propelled by the question of inevitable death, which Luther answers by moving from material and natural generation to the resurrection and then to the creatio ex nihilo . At the third site, Luther addresses such disturbing questions as the suffering of the righteous, the historical cycle of political power, and the harshness of reprobation. He answers these questions by integrating the symmetrical biblical statements of the annihilatio and the creatio with a theological theory of divine omnipotence. God's hiddenness is understood as God's omnipotence working at the specific locations of self-negation, as well as behind the ebb and flow of historical-political contingency. Faith presses into the hidden mystery, grounded in the certainty that all things are effected by the Creator whose nature is self-giving goodness, and established by the hope that the light of glory will determine more fully the God who is to be honored above all.     

Cognitive biases in the perception of discrimination: The importance of format

Previous work has shown that people seem less able to perceive sex discrimination on a personal level than on a societal level. The present experiment was performed to test the hypothesis that this phenomenon is in part an information-processing bias; that is, the perception of discrimination is more difficult when one makes case-by-case comparisons than when one encounters information in aggregate form. The experiment demonstrated the importance of formatting for the perception of discrimination. Among subjects with little or no emotional investment in the issue of sex discrimination, the format of the pertinent information has a large effect on information processing: subjects perceived less discrimination when they encountered the relevant information in little chunks than when they saw the total picture at a single shot.

Total sleep deprivation increases the costs of shifting between simple cognitive tasks

In two experiments we studied the effects of one night of total sleep deprivation on task-shift costs. In different conditions shifts were between types of judgment (extradimensional shifts) and between stimulus-response mappings (intradimensional shifts). In addition, with an alternating-runs procedure we used short and long response-to-stimulus intervals and also external precues to vary the opportunities for advance configuration of task sets. Under all conditions sleep deprivation increased shift costs derived from the 20% slowest reaction times, which were insensitive to the opportunities for advance configuration. Shift costs derived from the 20% fastest reaction times were increased only for extradimensional shifts. As indicated by congruency effects, the increase of shift costs after a night without sleep cannot be attributed to increased interference between competing task sets. The findings suggest that total sleep deprivation increases task-set instability and thus lapsing, in particular in conditions with long stimulus-to-response intervals and in shift trials. In addition total sleep deprivation seems to increase the duration of an exogenously controlled process involved in extradimensional shifts.     

Spontaneous and reactive attributions following academic achievement

This paper describes two studies which deal with attributions following academic achievement. Study 1 investigated the influence of different types of instructions (spontaneous vs. reactive), self-concepts of ability (high vs. low), and outcomes (success vs. failure) on causal attributions in a school setting. Participants were 402 eighth to tenth graders. Students with a low self-concept of ability produced more attributions than students with a high self-concept. Under reactive conditions, students' attributions following success were in accordance with the self-consistency theory. Under spontaneous conditions, these students produced attributions in a self-serving way. Furthermore, success evoked more attributions than failure. In Study 2, 160 university students worked on an unfamiliar task (a computer-simulated dynamic system). The results supported the assumption that students spontaneously generate attributions to raise or at least preserve their self-esteem.
