Liking Violence and Action: An Examination of Gender Differences in Children's Processing of Animated Content

It is widely assumed that children like violence in cartoons, but this assumption has not been supported in existing studies that show nonviolent programs are liked just as much or more than violent programs. The present experiment extended enjoyment of media violence research by testing whether violence and action (independently manipulated) influenced children's liking of slapstick cartoons. We also proposed a path model to test potential indirect effects of violence and action on liking. Using animation software, four versions of a slapstick cartoon were created that varied in terms of violence (present, absent) and action (high, low). A total of 128 elementary school children watched one of the four versions of the program. Violence had no direct effect on the liking of the cartoon, but did indirectly decrease liking for males by decreasing boys' wishful identification with the anthropomorphized characters. Action increased liking for males but not for females.     

Explanatory models for mental illness endorsed by Christian clergymen: The development and use of an instrument in Singapore

Researchers have attempted to elicit the explanatory models used by different populations to understand mental illness, since these models can influence how populations use mental-health treatment. However, little effort has been made to understand the explanatory models used by Christian clergymen. This is despite their important role as providers of mental-health care in many Asian and Western societies. Neither are there suitable instruments to conduct such investigations. This study attempts to present a suitable instrument for such research and explore the belief structure of this population by administering a modified version of the Opinions about Psychological Problems to a representative sample of Singaporean Christian clergymen. Factor-analytic techniques revealed five factors which were explained as (1) a Traditional Christian and (2) a Deliverance etiology, both models implicating religious causes for mental illness, (3) a Poor Coping and (4) Internal Conflicts etiology, essentially being psychological explanations and an (5) Organic etiology model. The Traditional Christian model received the greatest endorsement, followed by the Poor Coping model, while the Organic model had the least acceptance. The belief structure used by nearly half of the respondents was noted to be complex, involving a combination of religious, psychological, and organic explanations.     

Quantifying the Value of Emotions Using a Willingness to Pay Approach

People generally seek out positive moods and avoid negative moods; however, it is unclear which motivation is more pronounced. Two studies addressed this issue by developing a value-based ranking of emotions based on the willingness to pay (WTP) approach. The approach utilizes money’s cardinal properties and assumes opportunity costs as with everyday purchases. In Study 1 British participants indicated they would be willing to pay more to experience positive than to avoid negative emotions. In Study 2 this positivity bias was replicated with another sample of British participants. However, Hong Kong Chinese participants did not show such a preference, and were willing to pay significantly less to experience positive emotions but more to avoid negative emotions when compared with British participants. Experiencing Love was given the highest WTP judgment in all samples. Thus, some emotions are universally valued, whereas preferences for others differ across cultural groups, perhaps shaped by norms. Implications concerning valuations of psychological states for policy purposes are discussed.     

Body position differentially influences responses to exogenous and endogenous cues

The influence of vestibular inputs on exogenous (Exp. 1) and endogenous (Exp. 2) orienting of visual attention was examined. The vestibular system was manipulated through a change in static body position. Participants engaged in an exogenous or endogenous response task while in a seated position, while lying in a prone position, and while in a prone position with their head down and neck flexed (HDNF). An attenuation of inhibition and facilitation effects during the exogenous task was observed in the HDNF position. However, responses to the cues remained similar in the endogenous task, irrespective of body position. The results reveal a potential dissociation between reflexive and volitional orienting of visual attention that is dependent on vestibular inputs.     

A Church-Fitch proof for the universality of causation

In an attempt to improve upon Alexander Pruss’s work (The principle of sufficient reason: A reassessment, pp. 240–248, 2006), I (Weaver, Synthese 184(3):299–317, 2012) have argued that if all purely contingent events could be caused and something like a Lewisian analysis of causation is true (per, Lewis’s, Causation as influence, reprinted in: Collins, Hall and paul. Causation and counterfactuals, 2004), then all purely contingent events have causes. I dubbed the derivation of the universality of causation the “Lewisian argument”. The Lewisian argument assumed not a few controversial metaphysical theses, particularly essentialism, an incommunicable-property view of essences (per Plantinga’s, Actualism and possible worlds, reprinted in: Davidson (ed.) Essays in the metaphysics of modality, 2003), and the idea that counterfactual dependence is necessary for causation. There are, of course, substantial objections to such theses. While I think a fight against objections to the Lewisian argument can be won, I develop, in what follows, a much more intuitive argument for the universality of causation which takes as its inspiration a result from Frederic B. Fitch’s work (J Symb Logic 28(2):135–142, 1963) [with credit to who we now know was Alonzo church’s, Referee Reports on Fitch’s Definition of value, in: (Salerno (ed.), New essays on the knowability paradox, 2009)] that if all truths are such that they are knowable, then (counter-intuitively) all truths are known. The resulting Church–Fitch proof for the universality of causation is preferable to the Lewisian argument since it rests upon far weaker formal and metaphysical assumptions than those of the Lewisian argument.     

Testing Effects of Community Collaboration on Rates of Low Infant Birthweight at the County Level

Interorganizational collaboration has become a popular strategy for addressing population health and well-being. However, evidence for its effectiveness in achieving outcomes at the population level is limited, at least in part due to a variety of methodological challenges such as reduced sample size at the population level, the availability of suitable comparison groups of communities, and study durations that are too short to detect slowly emerging outcomes. The present study addresses these challenges by retrospectively examining the effectiveness of a mature network of community collaboratives, using latent growth modeling of longitudinal change in an archival community-level outcome, low infant birthweight, and propensity score matching of comparison communities. A group of 25 Georgia counties with collaboratives targeting low infant birthweight was compared to a weighted comparison group of counties from other southeastern states, using propensity score matching. We report results of full matching methods and outcome analyses examining differences in change in county rates of low infant birthweight from 1997 to 2004 between intervention and comparison counties. Results indicated significantly smaller increases in low weight birth rates in intervention counties than in comparison counties.
