Gender differences characterize children's commitment to playing electronic games. These gender differences are consistent with common stereotypes that may be triggered by the context and content of electronic games. If conforming to gender stereotypes in electronic game playing maintains social approval, then those children who choose alternate playing patterns risk social sanction. The present study was designed to characterize children's views of gender differences in social approval for electronic game playing. A questionnaire was administered to 364 fourth- and fifth-grade students (203 females) in a midwestern suburban school district. Approximately 12% of the students represented minorities, and the majority were African-American. Children responded to fourteen statements describing the social acceptability by gender of certain playing habits. Chi-square analyses identified important gender and grade differences. Many children endorsed statements indicating that social approval for game playing is consistent with common gender stereotypes. The most striking gender differences in perceived social approval were found in statements referencing fighting games. Children whose game playing deviates from approved patterns may represent a group of high-risk electronic game players. 相似文献

A community intervention to mobilize positive reinforcement for not selling tobacco to young people was evaluated. The intervention
had five components: (a) mobilization of community support, (b) merchant education, (c) changing consequences to clerks for
selling or not selling to those under 18, (d) publicity about clerks’ refusals to sell, and (e) feedback to store owners or
managers about the extent of their sales to adolescents. A multiple baseline design experiment was conducted, in which two
small Oregon communities received the intervention, while two others continued in baseline. Outlets’ willingness to sell was
assessed repeatedly by teenage volunteers. The intervention significantly reduced the proportion of stores willing to sell.
Mobilizing socia and material reinforcement for stores not selling tobacco to young people is a viable means of reducing such
sales. It may be especially valuable in communities where laws against sales to minors go unenforced.

This article expands the conceptual framework of considerations of the self and identity in career development theory and practice. A brief review of the existing self and identity constructs in career development theory is provided. Selected advances in theoretical considerations of the self and identity emerging from fields outside of the purview of career development are presented with a focus on the importance of the relational and cultural contexts. An “embeddedness” perspective is offered that describes the interdependence between intrapersonal experience and social, relational, historical, and cultural contexts. A case vignette is provided to illustrate the implications for practice of that perspective. 相似文献

This study assessed the relationship of depression, anxiety, and hostility to physical health in a multicultural student population
(N=106). When controlling for a variety of demographic and health risk factors (viz., age, sex, body mass, smoking, alcohol,
salt, caffeine, and exercise), hostility, depression, and anxiety were related to higher reported incidences of physical symptoms
and somatic illness. Depression and hostility had the strongest relationships with physical health, although the most striking
single relationship was between depression and illness. Results suggest that it may be premature to focus our attention on
hostility in research on the personality-illness relationship. They also suggest that the health behavior model of the relationship
between personality and disease does not provide an adequate explanation, since negative affect was significantly associated
with illness even when controlling for a variety of health risk factors.

Summary Butler and Hains (1979) found individual differences in the effect of word length on RT in word naming and lexical-decision tasks; subjects scoring high on a vocabulary test were much less affected by word length than subjects with low scores. The present study attempted to determine whether such differences could be due to differences in the use of intraword structure, since word recognition has been linked, both empirically (Mason, 1978; Scheerer-Neumann, 1981) and theoretically (Mewhort & Campbell, 1981) to the use of orthographic redundancy. In Experiment 1, subjects were shown tachistoscopically presented letter strings varying in approximation to English. High vocabulary subjects were more capable of capitalizing on the redundancy with the higher-order approximations. Experiment 2 then established that performance on the vocabulary test was correlated with reading skill, measured by the Nelson-Denny Reading Test, and that skilled readers were more sensitive to the syllable structure in words. In the experiment, subjects were shown eight-letter words presented as three separate word units which either matched or violated syllable boundaries in the word. Skilled readers were more sensitive to the difference between syllable and nonsyllable units than were less skilled readers. The results obtained by Butler and Hains appear to reflect differences in reading skill and the efficiency of letter sequence parsing prior to word recognition. 相似文献

A community program to reward children's use of seat belts 总被引:4,自引:0,他引:4

This paper reports on a community-wide effort to increase elementary school children's use of seat belts. Twenty-five schools serving over 9,000 children participated in a program of rewards (stickers, bumper strips, and chances on pizza dinners) administered by parent-teacher organization volunteers. Comprehensive observations were made at three representative schools. Categorization of compliance with safety rules required all passengers to be buckled into safety devices before the children received the rewards. The rewards, on average across schools, increased compliance from baseline of 18.1% to 62.4% during the interventions. Withdrawal of the rewards resulted in a decrease to 49% compliance, but this rate remained above baseline. The involvement of community groups and institutions in this safety program is highlighted. 相似文献
