This article summarizes the content analyses of male and female portrayals in U.S. television commercials that have been published since 1971. The paper also includes the results of a content analysis of television commercials conducted on a 1985 sample. Where possible, the data from the present study are compared to the findings of previous research to illustrate trends over time. The results reveal several differences between the portrayal of men and women, but many of the gaps seem to be narrowing. Men and women now appear equally often as central characters in prime-time commercials. Although a prior study indicated a difference between male and female primary characters' use of arguments, the present data revealed no differences in this regard. A lower percentage of female than of male central characters are depicted as employed, but males are being presented in increasing numbers as spouses and parents, with no other apparent occupation. Women are still more likely than men to be seen in domestic settings, advertising products used in the home. Although the difference seems to have become smaller, women are more likely than men to be shown as users of the products they advertise. The most striking gap persists with regard to narrators. Consistent with other content analyses conducted over the past 15 years, approximately 90% of all narrators are male. The findings are discussed in terms of the potential effect of exposure to stereotyped depictions on viewers' sex role attitudes.  相似文献

This experiment explores semantic processing of one message while another is attended to and shadowed. It was an attempt to replicate and clarify an earlier finding by Lewis (1970). Like Lewis, we found that mean shadowing latency was increased when a synonym of the shadowed word coincided with it on the unattended channel. However, this occurred only with synonyms in an early list position and appeared to affect only a small proportion of trials. The implications of this and other recent findings for theories of selective listening are discussed.  相似文献

In experimental designs requiring the administration of more than one treatment to the same subject(s), the effect of one treatment may be influenced by the effect of another treatment (Campbell & Stanley, 1963), a phenomenon known as multiple treatment interference. We conducted two studies in which multiple treatment interference in an alternating treatments design was shown to be a function of the length of the intercomponent interval (ICI) separating treatment conditions. In the first study, we evaluated the effects of four different treatments on the mouthing of a severely retarded boy. Under a 1-min ICI no consistent differential responding to treatment was obtained. Differential responding emerged when the ICI was increased from 1 min to 120 min, thus suggesting multiple treatment interference in the lack of differential responding under a 1-min changeover interval. Functional control of the nondifferential and differential responding as a function of the ICI length was replicated in a reversal phase. In the second study, we compared two treatment procedures for the disruptive noncompliant behavior of a moderately retarded boy. Multiple treatment interference (i.e., the lack of differential responding) occurred with the 1-min intercomponent interval. An increase to a 120-min ICI again resulted in differential responding. A replication of multiple treatment interference by a reversal to a short interval phase was not achieved in the second subject. Results of this study support much of the basic literature on discrimination and multiple treatment interference. Major findings of this study are twofold: Multiple treatment interference can depend on the length of the changeover interval between treatments and multiple treatment interference can take the form of a lack of differential responding to various treatments. Implications for future research are discussed.  相似文献

Within the investment theory of creativity (Sternberg & Lubart, 1996), creativity is defined as a 2-part process of buying low by investing in unusual ideas and then selling high by convincing others of the value or usefulness of these new ideas. This process requires both creative ideation and perseverance. The purpose of this research was to examine the psychometric properties of instrumentation proposed to assess the 2 underlying constructs in this definition: the creative ideational behavior required to buy low and the persevering behavior required to sell high. In particular, psychometric properties of a creativity ideation measure, the Runco Ideational Behavior Scale (RIBS Scale: Runco, Plucker, & Lim, 2001) and a perseverance measure, the Grit Scale (Duckworth, Peterson, Matthews, & Kelly, 2007) were examined in this study. Two samples of undergraduate students (= 187; = 817) completed a survey including these two scales and demographic information. Factor analyses were performed on the RIBS and Grit Scales. The RIBS Scale was found to have a 2-factor structure and 2 proposed new subscales. The Grit Scale’s previously reported 2-factor structure was confirmed.  相似文献

Background: Depression is among the most common mental health problems for young people. In adults, depression is associated with neurocognitive deficits that reduce the effectiveness of treatment and impair educational and vocational functioning. Compared to adults, less is known about the neurocognitive functioning of young people with depression, and existing research has reported inconsistent findings. Method: This systematic review and meta-analysis synthesized the literature on neurocognitive functioning in currently depressed youth aged 12–25 years in comparison to healthy controls. Results: Following a systematic review of the literature, 23 studies were included in the meta-analysis. Poorer performance in the domains of attention (SMD: .50, 95% CI: .18–.83, p?=?.002), verbal memory (SMD: .78, 95% CI: .50–1.0, p?<?.001), visual memory (SMD: .65, 95% CI: .30–.99, p?<?.001), verbal reasoning/knowledge (SMD: .46; 95% CI: .14–.79; p?<?0.001) and IQ (SMD: .32; 95% CI: .08–.56; p?=?0.01) were identified in depressed youth. Relative weaknesses in processing speed/reaction time and verbal learning were also evident, however, these findings disappeared when the quality of studies was controlled for. Moderator analysis showed a tendency for poorer set-shifting ability in younger depressed participants relative to controls (although non-significant; p?=?.05). Moderator analysis of medication status showed taking medication was associated with poorer attentional functioning compared to those not taking medication. Conclusion: The findings suggest that currently depressed young people display a range of neurocognitive weaknesses which may impact treatment engagement and outcome. The findings support the need to consider neurocognitive functioning when treating youth with depression.  相似文献

The promise of online cognitive behavioral therapy for insomnia (CBT-I) and other sleep-related problems as an alternative to traditional face-to-face treatment rests upon the accessibility, ease-of-use, and effectiveness of these approaches. Here we provide a review of Sleepio, a digitalized, state-of-the-art CBT-I program for adults, informed by our personal experience with the program, available research, and information provided at the Sleepio website. The 6-week treatment program can be completed flexibly via web-based or mobile platform. Initial assessment of individual goals and baseline sleep patterns is used to build a personalized account comprised of four sections: Sleep Diary, Case File, Library, and Community. Sleepio uses evidence-based principles and practices, engaging content, and an easy-to-follow format. Unique features of the program including synchronization with compatible sleep tracking devices, multiple built-in user supports, and a 14-day money-back guarantee. Both statistical and clinically meaningful sleep improvements have been found in a large randomized controlled trial. Overall, Sleepio represents a model program for online CBT-I delivery.  相似文献
