LEGO® construction sets are a staple in many children’s lives. Given worldwide distribution, generations of children have grown up playing with these brightly colored, interlocking plastic bricks. Historically marketed to all children, the LEGO® Group has begun targeting male and female consumers differentially with the introduction of product lines such as LEGO® City and LEGO® Friends. Although the packaging, marketing, brick colors, and characters have changed, little is known about whether these product series encourage differences in the way boys and girls play. This content analysis compared the play narratives of sets marketed to boys (LEGO® City) and girls (LEGO® Friends). Our analysis found distinct gendered messages that encourage boys to enact various skilled professions, heroism, and expertise, whereas girls are encouraged to focus on having hobbies, being domestic, caring for others, socializing, being amateurs, and appreciating and striving for beauty. Although LEGO® City and Friends sets offer opportunities for construction, they also promote stereotyped gender roles for enacting femininity and masculinity in play. Parents, educators, and practitioners often focus on the educational affordances of LEGO® construction. We recommend that they also consider the other lessons, both explicit and implicit, being taught through gender-specific LEGO® sets. 相似文献

Gender socialization influences children at early ages, shaping their developing identities. The toys provided by parents deliver some of the earliest gender-based messages by encouraging children to engage in activities associated with, for example, dolls and trucks. In the current study, we measured the influence of parental socialization by assessing 5- and 12 ½-month-old infants’ exposure to dolls and trucks and by experimentally manipulating parents’ encouragement to play with these toys. We found that infants displayed gender-typical toy preferences at 12 ½, but not 5 months, a pattern characteristic of previous studies. However, brief encouragement by a parent to play with toys from each category was ineffective in altering infants’ preferences. Rather, the types of toys present in the home predicted preferences, suggesting that at-home exposure to toys may be influential in the development of toy preferences. These findings reveal that socialization processes may indeed play a role in the formation of early gender-typical toy preferences and highlight the importance of equal toy exposure during infancy to ensure optimal development. 相似文献

It is important to identify predictors of psychological health among breast cancer patients that can be relatively easily identified by medical care providers. This article investigates the role of one class of such potential predictors: easily identified demographics that have potential social and/or practical implications. Specifically, we examined whether income, marital status, presence of children in the home, education, travel distance, age and rurality interact with time to predict psychological health over the first year post diagnosis. Two hundred and twenty five breast cancer patients receiving radiation treatment completed four surveys over the course of 13 months that included measures of both their physical health and depressive symptoms. The results revealed that women who were not married had children living in the home or had to travel long distances to receive radiation treatment reported higher levels of depressive symptoms across the entire study. Women with lower incomes reported increased depressive symptoms, but only after the completion of treatment. Younger women reported elevated depressive symptoms during initial treatment, but this effect dissipated after the completion of treatment. The current results suggest that demographic patient characteristics may indeed be useful in identifying both when and for whom depressive symptoms are particularly likely to be problematic. 相似文献

The purpose of this study was to examine the role of 2 types of social influence--general social support and living with a smoker--on smoking behavior among middle-aged and older women in the Women's Health Initiative (WHI) Observational Study. Participants were postmenopausal women who reported smoking at some time in their lives (N=37,027), who were an average age of 63.3 years at baseline. Analyses used multiple logistic regression and controlled for age, educational level, and ethnicity. In cross-sectional analyses, social support was associated with a lower likelihood and living with a smoker was associated with a higher likelihood of being a current smoker and, among smokers, of being a heavier smoker. Moreover, in prospective analyses among baseline smokers, social support predicted a higher likelihood and living with a smoker predicted a lower likelihood of smoking cessation 1-year later. Further, in prospective analyses among former smokers who were not smoking at baseline, social support predicted a lower likelihood and living with a smoker predicted a higher likelihood of smoking relapse 1-year later. Overall, the present results indicate that social influences are important correlates of smoking status, smoking level, smoking cessation, and smoking relapse among middle-aged and older women. 相似文献

This article presents the results of a qualitative analysis of interviews with 25 psychologists in independent practice, investigating everyday treatment decisions and attitudes about treatment outcome research and empirically supported treatments (ESTs). Clinicians noted positive aspects about treatment outcome research, such as being interested in what works. However, they had misgivings about the application of controlled research findings to their practices, were skeptical about using manualized protocols, and expressed concern that nonpsychologists would use EST lists to dictate practice. Clinicians reported practicing in an eclectic framework, and many reported including cognitive-behavioral elements in their practice. To improve their practice, they reported valuing clinical experience, peer networks, practitioner-oriented books, and continuing education when it was not too basic. Time and financial barriers concerned nearly all participants. Clinicians suggested they might be interested in ESTs if they could integrate them into their current frameworks, and if resources for learning ESTs were improved. 相似文献
