Concern is often expressed that mass media contribute to the early sexualization of young girls; however, few empirical studies have explored the topic. Using paper dolls, we examined self-sexualization among sixty 6–9?year-old girls from the Midwestern United States; specifically self-identification, preference, and attributions regarding sexualized dress. Based on simultaneous maternal reports, we also investigated potential risk factors (media consumption hours, maternal self-objectification) and potential protective factors (maternal television mediation, maternal religiosity) for young girls’ sexualization. Findings support social cognitive theory/social learning theory and reveal nuanced moderated effects in addition to linear main effects. Girls overwhelmingly chose the sexualized doll over the non-sexualized doll for their ideal self and as popular; however, dance studio enrollment, maternal instructive TV mediation, and maternal religiosity reduced those odds. Surprisingly, the mere quantity of girls’ media consumption (tv and movies) was unrelated to their self-sexualization for the most part; rather, maternal self-objectification and maternal personal religiosity moderated its effects.  相似文献

This study examined the relation between ethnically based rejection sensitivity and academic achievement in a sample of 936 immigrant students in Germany and Switzerland. The theory of race‐based rejection sensitivity that originated in North America was extended to immigrant students in Europe. The rough political climate against immigrants in Europe makes it probable that immigrant youth face particular difficulties and are affected by ethnically based rejection sensitivity, at least as much as—or even more than—minority youth in the United States. Using a standardized literacy performance test and multilevel analyses, we found that ethnically based rejection sensitivity was negatively related to academic achievement for immigrant students. This relation was partially mediated by a strong contingency of the students' self‐worth on the heritage culture, as well as by a low number of native German or Swiss majority‐group friends. We interpret these processes as immigrant students' efforts to cope with ethnically based rejection sensitivity by retracting into their heritage culture and avoiding majority‐group contact, which unfortunately, however, at the same time also results in lower academic achievement.

Fundamentalism is consistently related to racial prejudice (Hall, Matz, & Wood, 2010), yet the mechanisms for this relationship are unclear. We identify two core values of fundamentalism, authoritarianism and traditionalism, that independently contribute to the fundamentalism‐racial prejudice relationship. We also contextualize the fundamentalism‐racial prejudice relationship by suggesting that fundamentalists may show prejudice based on conceptions of African Americans as violating values but show tolerance when prejudice is less justifiable. These ideas are tested and confirmed using three data sets from the American National Election Studies. Across all three samples, fundamentalism is related to increases in symbolic racism but decreases in negative affect towards African Americans, and these relationships are mediated by both authoritarianism and traditionalism.  相似文献

Similar to certain bats and dolphins, some blind humans can use sound echoes to perceive their silent surroundings. By producing an auditory signal (e.g., a tongue click) and listening to the returning echoes, these individuals can obtain information about their environment, such as the size, distance, and density of objects. Past research has also hinted at the possibility that blind individuals may be able to use echolocation to gather information about 2-D surface shape, with definite results pending. Thus, here we investigated people’s ability to use echolocation to identify the 2-D shape (contour) of objects. We also investigated the role played by head movements—that is, exploratory movements of the head while echolocating—because anecdotal evidence suggests that head movements might be beneficial for shape identification. To this end, we compared the performance of six expert echolocators to that of ten blind nonecholocators and ten blindfolded sighted controls in a shape identification task, with and without head movements. We found that the expert echolocators could use echoes to determine the shapes of the objects with exceptional accuracy when they were allowed to make head movements, but that their performance dropped to chance level when they had to remain still. Neither blind nor blindfolded sighted controls performed above chance, regardless of head movements. Our results show not only that experts can use echolocation to successfully identify 2-D shape, but also that head movements made while echolocating are necessary for the correct identification of 2-D shape.  相似文献
