Dressing up with Disney and Make-Believe with Marvel: The Impact of Gendered Costumes on Gender Typing,Prosocial Behavior,and Perseverance during Early Childhood

Wearing costumes is a common experience during early childhood and is often important to sociodramatic play. Costumes tend to be highly gendered for both girls and boys (such as princess and superhero costumes). However, there is very little research on the impact that wearing costumes has on gender-differentiated behavior, such as toy preference, prosocial behavior, or perseverance during early childhood. The current study included 223 U.S. children, aged between 3 and 5 years-old. Children were assigned to wear either a gendered, counter-gendered, or gender-neutral costume, and they then took part in three gender-related tasks. There was no impact of wearing costumes on any task for girls. However, boys preferred feminine toys significantly more when wearing a neutral costume when compared to a masculine-typed one. Additionally, boys were significantly less likely to help when wearing a masculine-typed costume compared to a feminine-typed costume. There are several implications of these findings that are discussed in the paper. Parents may wish to purchase a wide range of costumes for their child for sociodramatic play, particularly for boys. Therapists could also potentially use costumes during play therapy to discuss gender issues. Additionally, costume producers could consider marketing a wide range of costumes for children as opposed to largely focusing on gendered ones.

     

Theories and Theoria of the Atonement: A Proposal

This article traces the origins of language about ‘theories’ of the atonement in Friedrich Schleiermacher and F.C. Baur’s historicization of Protestant theology in Germany. It follows the growth and promulgation of this conceptualization as it spread to America and Great Britain in the later nineteenth century. This approach contributed to the growth and development of the doctrine and its history, while severely limiting it in important ways. I note four dangers implicit within uncritical use of ‘theory’ language in studies of the history of the doctrine of the atonement, and conclude by arguing that a more fitting approach lies in the ancient and medieval concept of theoria, or contemplation, which serves as the broader telos for appreciating the riches we have in the work of Christ, within which modest contemporary notions of theory can and should play a role.     

Elevation and reduction of plasma tryptophan and their effects on aggression and perceptual sensitivity in normal males

Data from experimental animals suggest that 5-hydroxytryptamine (5HT) may have an inhibitory effect on aggression, while clinical studies have found a correlation between pathological aggression and low brain 5HT. To investigate this relationship further we used amino acid mixtures designed to raise or lower the levels of the 5HT precursor, tryptophan. Normal male subjects were given tryptophan-depleted, balanced, or tryptophan-supplemented ammo acid mixtures and tested for aggression 5 hours later. The balanced amino acid mixture served as a control for the tryptophan depletion and supplementation. Testing for aggression was done using the Buss paradigm in which subjects deliver electric shocks to a (nonexistent) partner in response to stimulus tones. Duration and intensity of shock delivered were the measures of aggression, while responsivity to the stimulus tones was the measure of perceptual sensitivity. Neither tryptophan supplementation nor tryptophan depletion had any effect on these measures of aggression or perceptual sensitivity. We conclude that raising or lowering the synthesis of brain 5HT through alterations in tryptophan availability does not influence aggression in normal males as measured by the Buss task.
