Is the news making us unhappy? The influence of daily news exposure on emotional states

There is evidence that exposure to negative news is making people feel bad, but not much is known about why this only affects some people or whether this also applies to everyday news exposure. This study examined the direct and indirect effects of daily news exposure on people's affective states. Using ecological momentary assessment (EMA), 63 respondents (24 men and 39 women) reported their news exposure and affective states five times a day for 10 days. In addition, personal relevance of the news and personality characteristics, neuroticism and extraversion, were assessed. Results showed that negative news perceptions were related to more negative affect and less positive affect, and these effects were moderated by personal relevance, but not personality characteristics. The implications of these outcomes are discussed.

Disentangling the relationship between hemispheric asymmetry and cognitive performance

It is widely believed that advantages of hemispheric asymmetries originated in better cognitive processing, hence it is often implied that the relationship between hemispheric asymmetry and cognitive performance is linearly positive: the higher the degree of lateralization in a specific cognitive domain, the better the performance in a corresponding task. Yet, the empirical evidence for this notion is mixed and the statistical methods to analyze this relationship have been criticized. The present study therefore investigated the relationship between hemispheric asymmetries and cognitive performance in two behavioral tasks (a left-lateralized word-matching task and a right-lateralized face-decision task) in 230 participants (140 women, 90 men) by using two different approaches. Both methods correspondingly revealed that a relationship between hemispheric asymmetries and cognitive performance does exist. Contrary to a positive (linear) relationship however, the data could be best described by an inverted U-shaped curve. Although the optimal degree of lateralization seemed to be task-specific, a slight or moderate degree of hemispheric asymmetry achieved best cognitive performance in all tasks. Moreover, performances deteriorated towards extreme ends of lateralization (i.e., participants with either extreme left or right hemispheric biases). Taken together, the present study provides evidence against the notion that higher lateralization is related to enhanced cognitive performance.     

An investigation of cross‐national differences in positivity and job satisfaction

The present research examined the role of national differences in positivity as an explanation of cross‐national variation in job satisfaction (JS) ratings. National positivity values were derived from a sample of current employees by calculating the mean residual in a regression of global JS on mean facet satisfaction ratings. As predicted, the positivity values derived in the present research showed convergent validity with other indices of nation‐level positivity, and national differences in extraversion. National differences in positivity showed significant incremental associations with national differences in JS ratings after controlling for the effects of acquiescence, perceived differences in working conditions, and national development. Theoretical and practical implications of the results are discussed.     

Die pharmakologische Behandlung der Bipolaren Störung

Da die Bipolare St?rung eine Erkrankung ist, die jahrelange Therapie erfordert, wird die Akuttherapie der manischen und depressiven Episode einer Bipolaren St?rung gemeinsam mit der Phasenprophylaxe besprochen. Bei der Phasenprophylaxe sollte generell jene Medikation gew?hlt werden, die schon in der Akuttherapie wirksam war. Dabei müssen individuelle substanzspezifische Nebenwirkungen beachtet werden.

The impact of fear appeals on processing and acceptance of action recommendations

A stage model of processing of fear-arousing communications was tested in an experiment that examined the impact of vulnerability to a severe health risk, the quality of the arguments supporting a protective action recommendation, and the source to which the recommendation was attributed, on processing and acceptance of the recommendation. Argument quality influenced attitudes toward the recommendation (but not intention to act), and this effect was mediated by negative thoughts about the recommendation. Vulnerability influenced intention to act (but not attitudes), and this effect was mediated by perceived threat and positive thoughts about the recommendation. The pattern of findings suggests that although vulnerability to a severe health risk induces biased processing of the recommendation, biased processing is restricted to intentions and does not compromise the evaluation of the recommendation. The theoretical and practical implications of these findings are discussed.     

Three Approaches to Doing Philosophy: a Proposal for Grouping Philosophical Exercises in Classroom Teaching

Classroom teaching has two aims: learning philosophy, that is, the great philosophers, and doing philosophy. This article provides an overview of thirty exercises that can be used for doing philosophy, grouped into three approaches. The first approach, doing philosophy as connective truth finding or communicative action, is related to such philosophers as Dewey and Arendt, and is illustrated by the Socratic method. The second, doing philosophy as test‐based truth finding, is related to such philosophers as Popper, and is illustrated by Community of Philosophical Inquiry. The third, doing philosophy as juridical debate, judging truth‐value and making judgment, is related to such philosophers as Foucault, and is illustrated by philosophical debate. The analysis shows that although the classical methods applied by the great philosophers appear to be missing from classroom exercises, they do, in fact, remain at the heart of the matter.     

Learning from human tutoring

Human one-to-one tutoring has been shown to be a very effective form of instruction. Three contrasting hypotheses, a tutor-centered one, a student-centered one, and an interactive one could all potentially explain the effectiveness of tutoring. To test these hypotheses, analyses focused not only on the effectiveness of the tutors' moves, but also on the effectiveness of the students' construction on learning, as well as their interaction. The interaction hypothesis is further tested in the second study by manipulating the kind of tutoring tactics tutors were permitted to use. In order to promote a more interactive style of dialogue, rather than a didactic style, tutors were suppressed from giving explanations and feedback. Instead, tutors were encouraged to prompt the students. Surprisingly, students learned just as effectively even when tutors were suppressed from giving explanations and feedback. Their learning in the interactive style of tutoring is attributed to construction from deeper and a greater amount of scaffolding episodes, as well as their greater effort to take control of their own learning by reading more. What they learned from reading was limited, however, by their reading abilities.     

Menstrual cycle-related changes of functional cerebral asymmetries in fine motor coordination

Fluctuating sex hormone levels during the menstrual cycle have been shown to affect functional cerebral asymmetries in cognitive domains. These effects seem to result from the neuromodulatory properties of sex hormones and their metabolites on interhemispheric processing. The present study was carried out to investigate whether functional cerebral asymmetries in fine motor coordination as reflected by manual asymmetries are also susceptible to natural sex hormonal variations during the menstrual cycle. Sixteen right-handed women with a regular menstrual cycle performed a finger tapping paradigm consisting of two conditions (simple, sequential) during the low hormone menstrual phase and the high estrogen and progesterone luteal phase. To validate the luteal phase, saliva levels of free progesterone (P) were analysed using chemiluminescence assays. As expected, normally cycling women showed a substantial decrease in manual asymmetries in a more demanding sequential tapping condition involving four fingers compared with simple (repetitive) finger tapping. This reduction in the degree of dominant (right) hand manual asymmetries was evident during the luteal phase. During the menstrual phase, however, manual asymmetries were even reversed in direction, indicating a slight advantage in favour of the non-dominant (left) hand. These findings suggest that functional cerebral asymmetries in fine motor coordination are affected by sex hormonal changes during the menstrual cycle, probably via hormonal modulations of interhemispheric interaction.
