Although content analyses have found that superhero programs in the media portray strong gender stereotypes of masculinity, little research has examined the effects of viewing such programs. In the current study, 134 mothers of preschool children (from the Western and Northwestern United States) reported their child’s superhero exposure in the media, male-stereotyped play, weapon play, and parental active mediation of the media at two time points (1 year apart). Results revealed that boys viewed superhero programs more frequently than girls, with nearly a quarter of boys viewing superhero programs at least weekly. Analyses revealed that superhero exposure was related to higher levels of male-stereotyped play for boys and higher levels of weapon play for both boys and girls from Time 1 to Time 2, even after controlling for initial levels. Parental active mediation did not negate these effects, and even served to strengthen one finding for girls. Specifically, among girls with high superhero exposure, weapon play was highest for girls who received frequent active mediation. Implications of the results are discussed with a focus on whether such programs are developmentally appropriate for preschool children.  相似文献

Abstract

This study surveys recently graduated sport psychology (SP) doctoral students' (N = 34) educational backgrounds, work experiences, and perceptions of the professional field of SP inside and outside the realm of academia. Special attention was given to subjects' perceptions and expectations with regard to applied work in SP, actual work experiences, and income. Findings indicate that almost all graduates are spending their time in a variety of work activities, i.e., some combination of teaching, research, consulting, administration, and coaching, with a strong emphasis on teaching in an academic institution. Gender analysis revealed that, in general, females earned 74% of what males earned; females earned 53% of what males earned outside academia. Graduates' personal comments suggest a concern about consumer demand and financial support offered applied professionals in SP as well as the adequacy of their own training to provide applied services. Implications for AAASP and SP program directors are provided.  相似文献

After staring at a pattern of tilted lines, subsequent lines appear to be tilted in the opposite direction (direct tilt aftereffect, TAE). In a previous fMRI study we have demonstrated a direct TAE solely induced by the mental imagination accompanied by adaptation of orientation-selective neurons located in the extrastriate cortex, supporting the assumption of a perception-like coding of mental images. In this study we enlarge and specify the evidence for a perception-like coding of orientation-imagination. First, we replicated the previously detected direct TAE induced by line imagination with altered design-variations to control possible perceptual task confounds. Second, we tried to induce two other orientation-specific aftereffects: indirect TAE and contrast-threshold elevation aftereffect by mental imagery. The results replicate a robust direct TAE by mental imagery and by visual stimulation, with no influence of attentional resource allocation or perceptual task confounds. We could not induce an indirect TAE, but observed a perception bias in the opposite direction of the indirect TAE. The mental imagery of lines induced no orientation-selective contrast-threshold elevation aftereffect. In general, mental imagery seems to influence visual perception, indicating that perceptual resources are used by mental imagery. However, the utilisation of visual resources seems to be somewhat different from utilisation by perception.  相似文献

We demonstrate ways to incorporate nondeterminism in a system designed to formalize the reasoning of agents concerning their abilities and the results of the actions that they may perform. We distinguish between two kinds of nondeterministic choice operators: one that expresses an internal choice, in which the agent decides what action to take, and one that expresses an external choice, which cannot be influenced by the agent. The presence of abilities in our system is the reason why the usual approaches towards nondeterminism cannot be used here. The semantics that we define for nondeterministic actions is based on the idea that composite actions are unravelled in the strings of atomic actions and tests that constitute them. The main notions used in defining this semantics are finite computation sequences and finite computation runs of actions. The results that we obtain meet our intuitions regarding events and abilities in the presence of nondeterminism.  相似文献

Using a between-participants experimental paradigm, the present study investigated U.S. adolescent boys’ (n = 96) and college men’s (n = 194) attitudes toward media images of male athletes as well as their thoughts about the athletes. Participants viewed either sexualized (i.e., skin exposed, sexual pose) or performance (i.e., in uniform and in action poses on the field/court) images of male athletes. They then rated the athletes’ competence, esteem, and sexual appeal and completed a writing task about their reactions to the images. Male viewers rated the sexualized athletes lower in competence and esteem and higher in sexual appeal compared to the performance athletes. These results have implications for advocacy efforts calling for less sexualization in today’s media environment.
