Sensori-motor spatial training of number magnitude representation

An adequately developed spatial representation of number magnitude is associated with children's general arithmetic achievement. Therefore, a new spatial-numerical training program for kindergarten children was developed in which presentation and response were associated with a congruent spatial numerical representation. In particular, children responded by a full-body spatial movement on a digital dance mat in a magnitude comparison task. This spatial-numerical training was more effective than a non-spatial control training in enhancing children's performance on a number line estimation task and a subtest of a standardized mathematical achievement battery (TEDI-MATH). A mediation analysis suggested that these improvements were driven by an improvement of children's mental number line representation and not only by unspecific factors such as attention or motivation. These results suggest a benefit of spatial numerical associations. Rather than being a merely associated covariate, they work as an independently manipulated variable which is functional for numerical development.     

Negative post-event processing and decreased self-appraisals of performance following social stress in childhood social anxiety: an experimental study

Cognitive models of social phobia (SP) assume that following social evaluative stress, individuals with SP engage into dysfunctional post-event processing (PEP), a detailed negative review of the past event. While previous research has already shown, that children with high levels of social fears suffer from more frequent negative PEP, it remains unclear how stable PEP is across time in this age group and whether it leads to degraded self-appraisals of performance. Therefore in the present study we exposed a group of high (HSA) and low socially anxious children (LSA; both n = 20), aged 10–12 years, to a social evaluative situation and assessed negative and positive PEP as well as self-rated performance at 2.5 h and one week after the task. Our results revealed that HSA children reported more negative PEP than LSA children, independent of levels of depression. Moreover, negative PEP was related to measures of social anxiety and performance ratings within the tasks. Only the performance ratings in HSA children worsened over the course of the following week and were related to more negative PEP. Thus, these results speak for the high clinical relevance dysfunctional PEP may have for the maintenance of social fears already in childhood.     

Imagery of errors in typing

Using a typing task we investigated whether insufficient imagination of errors and error corrections is related to duration differences between execution and imagination. In Experiment 1 spontaneous error imagination was investigated, whereas in Experiment 2 participants were specifically instructed to imagine errors. Further, in Experiment 2 we manipulated correction instructions (whether or not to correct errors) and controlled for visual feedback in executed typing (letters appearing on the screen or not). Participants executed and imagined typing proverbs of different lengths. Errors and error corrections explained a significant amount of variance of execution minus imagination differences in Experiment 1, and in Experiment 2 when participants were instructed to correct errors, but not when participants were instructed not to correct errors. In Experiment 2 participants corrected and reported more errors with than without visual feedback. However, the relation between execution − imagination duration differences and errors and error corrections was unaffected by visual feedback. The types of errors reported less often in imagination than in execution were related to processes in typing execution. We conclude that errors and error corrections are not spontaneously imagined during motor imagery, and that even when attention is drawn to their occurrence only some are imagined. This may be due to forward models not predicting all aspects of an action, imprecise forward models, or a neglect of monitoring error signals during motor imagery.     

The value of value: Further excursions on the meaning and role of customer value

Grounded on fundamental marketing principles, the concept of customer value has been revisited and refined by academicians and practitioners for the last 30 years. However, research devoted to achieving a consistent theoretical and conceptual development of value‐related concepts has proceeded apace without ever reaching full closure. The present essay seeks reasons behind remaining deficiencies in value‐related research and offers a review intended to move our understanding of customer value toward what promises to become a more enlightened future. The topic of value is approached by theoretical analysis and conceptual development. First, “the challenge” of value research is presented: the researcher faces a topic that is central to the marketing discipline but that suffers from various conceptual and methodological difficulties. Second, among the literature on value from the last three decades, two main research areas are selected: the conceptual delimitation and the methodological links between quality, satisfaction, and value. Third, as a conclusion, we identify several streams of research that promise to expand future knowledge in the area of customer value. Several tables and figures that provide a systematic and structured review of value‐related knowledge support this inventory of the state‐of‐the‐art in value research. Even the most patient theoretical development of value‐related concepts tends to resist full conceptual closure. The breadth of customer value and its richness for marketing implications encourage novel and refreshing approaches. Copyright © 2011 John Wiley & Sons, Ltd.     

A global workspace model for phenomenal and access consciousness

Both the global workspace theory and Block’s distinction between phenomenal and access consciousness, are central in the current debates about consciousness and the neural correlates of consciousness. In this article, a unifying global workspace model for phenomenal and access consciousness is proposed. In the model, recurrent neural interactions take place in distinct yet interacting access and phenomenal brain loops. The effectiveness of feedback signaling onto sensory cortical maps is emphasized for the neural correlates of phenomenal consciousness. Two forms of top-down attention, attention for perception and attention for access, play differential roles for phenomenal and access consciousness. The model is implemented in a neural network form, with the simulation of single and multiple visual object processing, and of the attentional blink.     

Parenting,Mental Health and Culture: A Fifth Cross-Cultural Research on Parenting and Psychological Adjustment of Children

We examined psychological disorders across cultures and their associations with parental factors (control, inconsistency, and rejection). A questionnaire assessing psychological disorders was administered to male and female adolescents in nine countries. The results showed that psychological disorders differ across cultures. Parental factors are associated with each other and have a great deal of shared variance. The associations between psychological disorders and all parental factors were examined together in one regression and significant associations were found with maternal control, paternal temporal inconsistency, maternal situational inconsistency, paternal rejection and maternal rejection. Parental rejection appears to be a robust and influential factor influencing adolescents’ psychological disorders. The total variance of psychological disorders explained by all the parenting factors was low. The results revealed the flaws of reductionism in research and highlight the importance of studying associations of psychological disorders with various parental factors simultaneously and in conjunction with other familial, social and genetic factors.     

Post-event Processing in Children with Social Phobia

In the aftermath of a distressing social event, adults with social phobia (SP) engage in a review of this event with a focus on its negative aspects. To date, little is known about this post-event processing (PEP) and its relationship with perceived performance in SP children. We measured PEP in SP children (n = 24) and healthy controls (HC; n = 22), aged from 8 to 12 years, after the Trier Social Stress Test for Children (TSST-C). Children also rated their performance immediately after the TSST-C and 2.5 h later. SP children reported more negative and less positive PEP than controls. Regression analyses indicated that negative PEP was associated with social anxiety and perceived task performance independent of comorbid depression. The SP group rated their performance immediately after the TSST-C as worse compared to HCs and ratings remained stable over the following 2.5 h. Results are discussed in relation to current theories of SP.     

Two- vs. three-dimensional presentation of mental rotation tasks: Sex differences and effects of training on performance and brain activation

The well-documented sex difference in mental rotation favoring males has been shown to emerge only for 2-dimensional presentations of 3-dimensional objects, but not with actual 3-dimensional objects or with virtual reality presentations of 3-dimensional objects. Training studies using computer games with mental rotation-related content have demonstrated training effects on mental rotation performance. Here, we studied the combined effect of a two-week mental rotation (MR) training on 2-dimensional vs. 3-dimensional presentations of a classic Shepard–Metzler task (presented in a pretest–training–posttest design) and their accompanying cortical activation patterns assessed via EEG in a sample of 38 male and 39 female adolescents of about 15 years of age. Analysis of one performance parameter (reaction times) displayed only main effects of dimensionality (with shorter RTs on the 3D vs. 2D version of the MR task) and of training (significant shortening of RTs), but no significant sex difference. Analysis of the other performance parameter (scores) in the MR task revealed a sex difference favoring males that first, appeared only in the 2D version, but not in the 3D version of the MR task and, secondly, diminished after training. Neurophysiologically we observed a complex sex × dimensionality × training × hemisphere interaction showing that the hypothesized decrease of brain activation (increase in neural efficiency) with training emerged for males in both 2D and 3D conditions, whereas for females this decrease was found only in the 3D but not with the 2D version of the MR task.     

Every look matters: appraisals of faces follow distinct rules of information integration under arousing versus non-arousing conditions

In this research, we investigated whether appraisals of faces follow distinct rules of information integration under arousing versus non-arousing conditions. Support for this prediction was found in four experiments in which participants observed angry (and fearful) faces that were presented with a direct versus an averted gaze (Experiments 1a, b), on a red versus a grey background (Experiment 2), and after performing a motor exercise versus no exercise (Experiment 3). Under arousing conditions, participants’ appraisals of faces reflected summation (i.e. extremely negative encounters were strengthened by moderately negative encounters) whereas, under non-arousing conditions, appraisals did not reflect summation (i.e. extremely negative encounters were weakened by moderately negative encounters) and could instead be accounted for by three alternative rules of information integration based on averaging, mere exposure, or the number of strong stimuli.
