Previous content analyses of magazine images have typically examined within genres but failed to include comparisons between publications intended for various populations. The purpose of this study was to examine depictions of muscularity and thinness of male images in several widely distributed magazines that target male audiences from a variety of genres. Twenty-three magazine titles with the highest circulation rates that targeted heterosexual men, gay men, and general audiences were selected for image analyses. We found that magazines that target gay male audiences depicted images of men who were thinner in comparison to magazines targeting heterosexual men. Both gay and heterosexual magazines depicted male images with greater muscularity than magazines intended for general audiences. Differences in male image depictions in magazines may contribute to the promotion of an unattainable body ideal in some subgroups of gay culture.  相似文献

Situations in which there are multiple changes occurring all at once and which demand complex decisions to be made are common throughout life, but little is known about how normal aging influences performance on these types of scenarios. To determine performance differences associated with normal aging, we test older and younger adults in a dynamic control task. The task involves the control of a single output variable over time via multiple and uncertain input controls. The Single Limited Input, Dynamic Exploratory Responses (SLIDER) computational model, is implemented to determine the behavioral characteristics associated with normal aging in a dynamic control task. Model-based analysis demonstrates a unique performance signature profile associated with normal aging. Specifically, older adults exhibit a positivity effect in which they are more influenced by positively valenced feedback, congruent with previous research, as well as enhanced exploratory behavior.  相似文献

Philosophers disagree about what precisely makes an act paternalistic, and about whether, when, and why paternalistic acts are morally objectionable. Despite these disagreements, it might seem uncontroversial to think that it is permissible to paternalize children. When paternalism seems morally objectionable, that is usually because an adult has been treated in a way that seems appropriate only for children. But, we might think, there can be nothing morally objectionable about treating children as children. In this paper, however, I argue that there are limits to how we may permissibly paternalize children. I begin in Section 1 by describing and endorsing Jonathan Quong’s account of paternalism, which defines paternalistic acts as those that involve particular kinds of judgments that the paternalizer makes about the capacities of the paternalizee. In Section 2, I identify a distinction between two kinds of paternalism: ‘compensatory’ paternalism, and ‘non-compensatory’ paternalism. In Section 3, I argue that compensatory paternalism is usually permissible in the case of children. In section 4, I argue that non-compensatory paternalism is much harder to justify than compensatory paternalism, and because of this, it is sometimes impermissible even when directed at children.  相似文献

Background: A growing body of research has examined transgender identity development, but no studies have investigated developmental pathways as a transactional process between youth and caregivers, incorporating perspectives from multiple family members. The aim of this study was to conceptualize pathways of transgender identity development using narratives from both transgender and gender-nonconforming (TGN) youth and their cisgender (nontransgender) caregivers.

Methods: The sample included 16 families, with 16 TGN youth, ages 7 to 18 years, and 29 cisgender caregivers (N = 45 family members). TGN youth represented multiple gender identities, including trans boy (n = 9), trans girl (n = 5), gender-fluid boy (n = 1), and girlish boy (n = 1). Caregivers included mothers (n = 17), fathers (n = 11), and one grandmother. Participants were recruited from LGBTQ community organizations and support networks for families with transgender youth in the Midwest, Northeast, and South regions of the United States. Each family member completed a one-time, in-person semistructured qualitative interview that included questions about transgender identity development.

Results: Analyses revealed seven overarching themes of transgender identity development, which were organized into a conceptual model: Trans identity development, sociocultural influences/societal discourse, biological influences, family adjustment/impact, stigma/cisnormativity, support/resources, and gender affirmation/actualization.

Conclusions: Findings underscore the importance of assessing developmental processes among TGN youth as transactional, impacting both youth and their caregivers.  相似文献

We explored the differences between metamemory judgments for titles as well as for melodies of instrumental music and those for songs with lyrics. Participants were given melody or title cues and asked to provide the corresponding titles or melodies or feeling of knowing (FOK) ratings. FOK ratings were higher but less accurate for titles with melody cues than vice versa, but only in instrumental music, replicating previous findings. In a series of seven experiments, we ruled out style, instrumentation, and strategy differences as explanations for this asymmetry. A mediating role of lyrics between the title and the melody in songs was also ruled out. What emerged as the main explanation was the degree of familiarity with the musical pieces, which was manipulated either episodically or semantically, and within this context, lyrics appeared to serve as an additional source of familiarity. Results are discussed using the Interactive Theory of how FOK judgments are made.  相似文献

Many adolescents experience peer victimization, which often can be homophobic. Applying the minority stress model with attention to intersecting social identities, this study tested the effects of general and homophobic victimization on several educational outcomes through suicidality and school belonging among 15,923 adolescents in Grades 7 through 12 on account of their sexual orientation and race/ethnicity. Parent support also was tested as a moderator of these effects. Homophobic victimization had different effects on suicidality across groups, indicating the importance of considering individuals' multiple social identities. However, homophobic victimization had universal negative effects on school belonging for all groups. Nearly all indirect effects of general and homophobic victimization on reported grades, truancy, and importance of graduating were significant through suicidality and school belonging across groups. Parent support was most consistent in moderating the effects of general and homophobic victimization on suicidality for heterosexual White and racial/ethnic minority youth. In nearly all cases, it did not moderate the effects of general or homophobic victimization for lesbian, gay, bisexual, transgender, and questioning youth. Furthermore, in most cases, parent support did not moderate the effects of general or homophobic victimization on school belonging. Findings underscore the need for counseling psychologists to work with parents of all youth on ways to provide support to those who experience homophobic victimization. Furthermore, they highlight the need for counseling psychologists to be involved as social justice advocates in the passage and implementation of school policies that address homophobic bullying and other forms of bias-based bullying and harassment.  相似文献
