Drawing upon the theoretical framework of social identity theory and literature on physical intimacy, consumer neuroscience, and social cognitive and affective neuroscience, responses to images featuring same-gender and other-gender pairs are explored through examination of self-reported attitudes and neural activity associated with attention, memory, and emotion. Under the pretense of pretesting the effectiveness of images to be used in a national advertising campaign, participants viewed still images while neuroelectric brain responses were recorded. Each image featured two women, two men, or a man and a woman presented in positions of physical intimacy. Results indicated that event-related brain potentials (ERPs) associated with attention did not differ overall based on couple composition. However, ERPs associated with working memory and emotion were enhanced when processing images with two men. Preference for these images was reflected in self-reported attitudes. 相似文献

This study explores the library instructional programming and resources of high school library media centers in western Montana with the intent of documenting and understanding both the services provided to and the experiences of first-year college students at the University of Montana. Results from the survey (n = 22) and site visits (n = 10) reveal wide variation in the levels and types of library instructional programming provided at the library media centers, including media specialists’ perceptions of high school students’ information literacy skills. However, consistency was seen in the media specialists’ collection management strategies and in collection content. The results suggest implications for first-year library programming and highlight opportunities for further 9–16 collaboration and study. 相似文献

Although the importance of phonological awareness has been discussed widely in the research literature, the concept is not well understood by many classroom teachers. In the study described here, we worked with groups of kindergarten and first-grade teachers (the experimental group) during a 2-week summer institute and throughout the school year. We shared with them research about learning disabilities and effective instruction, stressing the importance of explicit instruction in phonological and orthographic awareness. We followed the experimental group and a control group into their classrooms for a year, assessing teachers' classroom practices and their students' (n = 779) learning. The study yielded three major findings: We can deepen teachers' own knowledge of the role of phonological and orthographic information in literacy instruction; teachers can use that knowledge to change classroom practice; and changes in teacher knowledge and classroom practice can improve student learning. 相似文献

Two pigeons were trained on a six-key modified oddity-from-sample procedure. The stimuli were olor pictures of birds, butterflies, and human faces. Initially, the third peck on the sample key which presented one of three different bird pictures) lit only one comparison key. Every three dditional pecks on the sample illuminated another comparison key. Fifteen sample pecks produced he maximum of five comparison stimuli. A peck on the comparison key that presented the non-atching bird picture produced grain. Pecks on matching keys turned off all the comparison keys nd repeated the trial. The birds learned to peck each sample until the non-matching comparison timulus was produced, and then to peck that key. After acquisition (70%–90% accuracy), the hree bird stimuli were replaced by a new set of three bird pictures. Subsequent phases provided ew sets of bird, butterfly, and human face stimuli. Both birds showed transfer of oddity learning o the novel samples. The data suggest that the birds may have been engaging in conceptual-type oddity learning, rather than learning discrete five-key discriminations or a series of two component chains. 相似文献

AIMS AND OBJECTIVES: Access to health information is important for the well-being of people living in the community after spinal cord injury (SCI). In order to design appropriate information interventions, it is critical first to understand the information sources typically used. The goal of this study therefore is to identify the information-seeking practices of this group. SAMPLE AND METHODS: A sample of 207 individuals living in the community following traumatic spinal cord injury were surveyed regarding their ongoing information needs and practices for seeking information. RESULTS: The results reveal that respondents have unmet information needs, despite the fact that they typically access information through a variety of channels. SCI specialists are the most commonly used source, although they are viewed as relatively inaccessible. By contrast, the Internet (used by a relatively high proportion of respondents) is viewed as comparatively accessible, although there are some concerns about the quality of information found there. CONCLUSIONS: These survey results point to the need for an information source that is accessible and delivers high quality information. Although respondents use a variety of information sources, none meets this ideal profile. Information professionals should consider this gap in the design of information interventions. 相似文献
