This research considers how distinct news frames work in combination to influence information processing. It extends framing research grounded in prospect theory (Tversky & Kahneman, 1981) and attribution theory (Iyengar, 1991) to study conditional framing effects on associative memory. Using a 2 × 3 experimental design embedded within a probability survey (N= 379), tests examined the effects of two different frame dimensions—loss‐gain and individual‐societal—on the complexity of individuals' thoughts concerning the issue of urban growth. Findings indicate that news frames interact to generate more or less complex cognitive responses, with societal‐gain frame combinations generating the most detailed cognitions about the causes, components, and consequences of urban growth. Directions for research on media framing are discussed. 相似文献

We draw on the recently developed communicative ecology model of successful aging (CEMSA) to examine how adults communicate about aging and how these communication patterns relate to experiences of successful aging. Using latent class analysis across 2 datasets collected in New Zealand and the United States, we identify 3 distinct classes of agers (disengaged, engaged, and bantering) defined by different profiles of communication behavior. Across samples, an engaged profile was generally associated with the most positive experiences of aging, whereas a disengaged profile was associated with the least positive experiences, although these differences were surprisingly small. Our results highlight the diverse ways in which individuals communicatively engage with the process of aging and experience aging as positive and successful. 相似文献

Three forms related to different age groups are discussed. Special attention is devoted to laboratory analyses in support of clinical diagnosis. A representative sample of sera from the healthy population of Thuringia showed 6.97 per cent positive sera. The difference between the exposed agricultural and forestry workers and industrial workers is significant. Moreover, there is a relationship between the extent of wooded country and the presence of microfoci. 相似文献
