We appreciate the efforts of Bushman, Gollwitzer, and Cruz (2015) to provide new data describing parents' and professionals' opinions regarding effects of media violence. Unfortunately, we feel it is necessary to call attention to apparent errors and inaccuracies in the way those data are interpreted and represented in their article. The article includes flawed analyses, overstates the extent to which there is agreement that media violence has meaningful negative societal effects, and misrepresents the relevance of the study to an understanding of the effects of media violence on societal violence. In contrast, we call for a climate of research on media violence that better recognizes the diversity of findings and conclusions in an active and growing research agenda and eschews unwarranted insinuations about effects on criminal violence from research focused on aggression-related measures not assessing violent crime.
The purpose of this study was twofold: (1) to further validate categories for the movement pattern of supine to standing in adults and (2) to evaluate the influence physical activity might have on the movement patterns used for rising. Seventy-two adults, between 30 and 39 years of age (mean = 34.1, SD = 2.8), performed the rising task while being videotaped. Subjects were divided into three groups by self-reports of level of physical activity (daily to rarely). Individual videotaped trials were classified using the previously described categories. Comparisons among the activity-level groups revealed that more active subjects demonstrated more developmentally advanced movement patterns in the righting task, consistent with earlier research on older adults. Results suggest that lifestyle patterns of regular, moderate physical activity may influence how a person performs the basic righting task of coming from a supine to a standing position. This investigation also provided additional support for the use of developmental sequences for the movement pattern of supine to standing.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
