Backbiting and bloodshed in books: short-term effects of reading physical and relational aggression in literature

The current research consisted of two studies examining the effects of reading physical and relational aggression in literature. In both studies, participants read one of two stories (containing physical or relational aggression), and then participated in one of two tasks to measure aggression. In Study 1, participants who read the physical aggression story were subsequently more physically aggressive than those who read the relational aggression story. Conversely, in Study 2, participants who read the relational aggression story were subsequently more relationally aggressive than those who read the physical aggression story. Combined, these results show evidence for specific effects of reading aggressive content in literature.     

The effect of intensity on relative pitch

In two experiments, we examined the effect of intensity and intensity change on judgements of pitch differences or interval size. In Experiment 1, 39 musically untrained participants rated the size of the interval spanned by two pitches within individual gliding tones. Tones were presented at high intensity, low intensity, looming intensity (up-ramp), and fading intensity (down-ramp) and glided between two pitches spanning either 6 or 7 semitones (a tritone or a perfect fifth interval). The pitch shift occurred in either ascending or descending directions. Experiment 2 repeated the conditions of Experiment 1 but the shifts in pitch and intensity occurred across two discrete tones (i.e., a melodic interval). Results indicated that participants were sensitive to the differences in interval size presented: Ratings were significantly higher when two pitches differed by 7 semitones than when they differed by 6 semitones. However, ratings were also dependent on whether the interval was high or low in intensity, whether it increased or decreased in intensity across the two pitches, and whether the interval was ascending or descending in pitch. Such influences illustrate that the perception of pitch relations does not always adhere to a logarithmic function as implied by their musical labels, but that identical intervals are perceived as substantially different in size depending on other attributes of the sound source.     

Creating Greener Citizens: Political Liberalism and a Robust Environmental Education

Proponents of environmentalist views often urge the teaching of such views and the inculcation of ‘green’ values within the educational curriculum of schools as a key component of achieving their ends. It might seem that modern versions of political morality that refuse to take a stance on controversial questions—religious, ethical, philosophical—or eschew appeal to perfectionist doctrines, such as Rawlsian political liberalism, are beset by a particularly acute difficulty in this regard. To the extent that environmentalist views embody claims about ethical matters such as how individuals should live their lives, they fall foul of this version of political morality. This article evaluates the resources available to political liberalism to respond to the challenge of bringing the teaching of green values and virtues within the national curriculum. It argues that environmental concerns differ in morally important ways from other ethical, philosophical, and religious views that are typically off-limits to political liberalism. Much that passes as green ideals are not simply a conception of the good life in the manner that religious views, for example, are. Rather, many environmental goods are crucial to the realisation of socioeconomic justice and therefore escape the requirement of state neutrality on endorsing the truth or importance of their role. A minimal political liberal education includes teaching about justice-based concerns as part of a compulsory national curriculum.     

Internet Search Behaviors and Mood Alterations: A Selective Exposure Approach

The present study has been designed in an attempt to replicate and expand the parameters of D. Zillmann and J. Bryant's selective exposure approach to use of the Internet. In applying this theoretical framework to the Internet, it was expected that persons experiencing unpleasant levels of excitation would arrange their Internet environment in order to terminate their aversive states. Through experimentally manipulating levels of boredom and stress and subsequently recording Internet surfing patterns, it was found that although mood significantly predicted Internet hits, it was not associated with the hedonic valence of the site.     

Economic Disadvantage and Young Children’s Emotional and Behavioral Problems: Mechanisms of Risk

This study aimed to establish potential mechanisms through which economic disadvantage contributes to the development of young children’s internalizing and externalizing problems. Prospective data from fetal life to age 3 years were collected in a total of 2,169 families participating in the Generation R Study. The observed physical home environment, the provision of learning materials in the home, maternal depressive symptoms, parenting stress, and harsh disciplining practices were all analyzed as potential mediators of the association between economic disadvantage and children’s internalizing and externalizing problem scores. Findings from structural equation modeling showed that for both internalizing and externalizing problems, the mechanisms underlying the effect of economic disadvantage included maternal depressive symptoms, along with parenting stress and harsh disciplining. For internalizing but not for externalizing problem scores, the lack of provision of learning materials in the home was an additional mechanism explaining the effect of economic disadvantage. The current results suggest that interventions that focus solely on raising income levels may not adequately address problems in the family processes that emerge as a result of economic disadvantage. Policies to improve the mental health of mothers with young children but also their home environments are needed to change the economic gradient in child behavior.
