The effects of violent video games on aggression.

Violent content video games such as Mortal Kombat and Doom have become very popular among children and adolescents, causing great concern for parents, teachers, and policy makers. This study cumulates findings across existing empirical research on the effects of violent video games to estimate overall effect size and discern important trends and moderating variables. Results suggest there is a smaller effect of violent video games on aggression than has been found with television violence on aggression. This effect is positively associated with type of game violence and negatively related to time spent playing the games. Directions for future programmatic research on video games are outlined.     

Infants avoid 'labouring in vain' by attending more to learnable than unlearnable linguistic patterns

Every environment contains infinite potential features and correlations among features, or patterns. Detecting valid and learnable patterns in one environment is beneficial for learners because doing so lends predictability to new environments where the same or analogous patterns recur. However, some apparent correlations among features reflect spurious patterns, and attempting to learn the latter costs time and resources with no advantage to the learner. Thus, an efficient learner in a complex environment needs to devote more attention to input that reflects a real and learnable pattern than to input that reflects a spurious or ultimately unlearnable pattern. However, in order to achieve such efficiency in the absence of external feedback, learners need to have an implicit metric of their own learning progress. Do human infants have such a metric? Data from two experiments demonstrate that 17‐month‐olds attend longer to learnable vs. unlearnable linguistic grammars, taking more trials to habituate and more overall time to habituate for grammars in which a valid generalization over input stimuli can be made. These data provide the first evidence that infants have an implicit metric of their own learning progress and preferentially direct their attention to learnable aspects of their environment.     

Addressing Criticisms of Global Religion Research: A Consumption‐Based Exploration of Status and Materialism,Sustainability, and Volunteering Behavior

Religion is a key source of core values and one of the most deeply psychological experiences; however, prior research has often inadequately measured religion's influence on consumption behaviors. Our research addresses criticisms of prior research by (1) reducing cultural bias by conducting research within one country, (2) examining both religious affiliation and religiosity, (3) exploring numerous consumption behaviors (social status desire, materialism views, sustainable behaviors, environmental views, and volunteering behavior) in a within‐subjects design, and (4) testing religion's effect on consumption behavior with over 1,000 participants. Findings provide insight for consumer well‐being. Specifically, consumers high in external religiosity are more materialistic, more sustainable, and more likely to volunteer than consumers low in external religiosity. Consumers high in internal religiosity are also more likely to be sustainable and hold pro‐environmental views. In addition, Buddhists and Hindus are less likely to hold pro‐environmental views than Christians. Buddhists are more materialistic than Christians, and Hindus are less desiring of social status than Christians. In addressing the criticisms of prior research in the context of consumption, our research builds on values‐based and social‐based theories.     

Carrying the Pain: The Journey from Suffering to Transformation—Perspectives from Shakespearean Tragedy and Pastoral Care

This paper proposes an admittedly difficult thesis that emotional pain and suffering can be good news. Rather than denying and running from emotional pain and suffering, we suggest embracing and carrying the pain. Through academic and spiritual writings, an observation of Hamlet’s tragic suffering, an examination of pastoral care case study data, and a B.L.E.S.S. acronym, this paper proposes that within the experience of suffering lies the transformative potential for meaning and fullness.     

Values of fathers for themselves and their newborns

The paternal role has been neglected in parenting research. The present study focused on the values of fathers of newborns. Values of fathers of newborns drawn from the inner-city lower-class were compared with values of fathers of newborns drawn from the middle class. Highest goals of fathers from both groups for themselves were economic ('family security'); values for their children were morally focused ('honest'). Inner-city fathers placed a higher value on a clean and obedient child, whereas middle-class fathers placed a higher value on a loving and imaginative child. When values of these fathers were compared with values of a similar sample of mothers of newborns, socioeconomic status remained an important predictor of values. Sex of parent was significant in the inner-city sample as these fathers placed a higher valuation on goals associated with autonomy than did inner-city mothers.     

Trust and Trustworthiness of Christians,Muslims, and Atheists/Agnostics in the United States

Trust, a cornerstone of economic development, is promoted within religions. In a randomized controlled trial, we examine how trust and trustworthiness vary across religions (Christianity and Islam), religiosity, and atheists/agnostics in the United States. Three novel findings emerge. First, Christians are trusted more than Muslims and nonbelievers, which is due to a Christian ingroup bias––Christians trust Christians more than they trust Muslims and nonbelievers, while Muslims and nonbelievers trust all groups the same. Second, religiosity matters to trust. Religious people trust those of higher religiosity more, but only if they are of the same religion. In contrast, nonbelievers trust people of higher religiosity less. Third, trustworthiness among nonbelievers is somewhat lower than that of the religious, especially toward Christians. We speculate that the lower reciprocity originates in the prejudice toward nonbelievers. Our results may help explain discrimination against Muslims and nonbelievers, given that discrimination often originates in distrust.     

The Iowa Child Welfare Research Station and the 1940 debate on intelligence: Carrying on the legacy of a concerned mother

During the late 1930s and early 1940s the nature-nurture issue regarding intelligence generated considerable controversy. The focus of attention for this debate was the Thirty-Ninth Yearbook of the National Society for the Study of Education, published in 1940. The Iowa Child Welfare Research Station played a prominent role in this debate. The Iowa researchers, led by George D. Stoddard and Beth L. Wellman, advocated an environmentalist position which challenged the more established hereditarian position held by Lewis M. Terman and his research associates. The Iowa position was closely related to the institutional context of the Child Welfare Research Station.
