Subjects wore a long-wavelength passband filter over one eye for 1 week. As a consequence, for that eye only, sensitivity to long-wavelength stimuli declined, unique yellow shifted to longer wavelengths, and scotopic stimuli acquired a strikingly bluish appearance. These results make it very likely that long-term exposure to a long-wavelength world can induce relatively prolonged (at least hours) postreceptoral adaptation. 相似文献

This investigation assesses the attitudinal impact of one of America’s most distinctive and famous group activities—jury deliberation. Tocqueville and the U.S. Supreme Court have both reasoned that jury service can promote civic engagement and recent research supports this view. The present study examines whether the attitudinal impact of jury deliberation depends on the quality of one’s jury experience. Two panel surveys of 2,410 total jurors tested the reciprocal relationship between the subjective experience of deliberation and the changes in civic attitudes toward oneself, fellow citizens, and public institutions. Principal results of structural equation models showed multiple effects of jury deliberation on attitudes, but there were no effects on one’s civic identity and political self‐efficacy. Reciprocally, every civic attitude except faith in fellow citizens was predictive of deliberative experience in at least one of the two studies. Overall, the study bolsters the claim of deliberative democratic theorists that the experience of consequential face‐to‐face talk can make private individuals into public citizens by reinforcing their confidence in fellow citizens and public institutions. 相似文献

In this paper we argue that comprehension is a problem solving activity and that different problem solving schemata exist for different types of texts, both narrative and expository. When processing the text, the reader uses these problem solving schemata to construct meaning of the context and to satisfy personal reading goals. For instance, comprehension of a text, such as a short story, a folk tale, or even a passage from a science book, can be viewed as a problem solving activity. Bransford and Stein's (1984) IDEAL model identifies the problem solver as one who (I) identifies problems, (D) defines and represents problems, (E) explores possible strategies for solving the problem, (A) acts on those strategies, and (L) looks back and evaluates the effects of those strategies. This problem solving model aptly describes what readers as problem solvers do when comprehending a text. The reader as a problem solver identifies and defines specific reading goals. To understand the content of the passage, the reader as a problem solver uses domain‐specific knowledge about the topic, prior experience in reading that type of text to explore a multitude of strategies. While reading the text, the reader uses those strategies to construct meaning about the text. After reading a passage, the proficient reader as a problem solver evaluates what has been read and checks to see if one's reading goals have been met. 相似文献

Abstract Proponents of character education (e.g., Bennett, author of The Book of Virtues) argue that children should hear moral stories in order to develop moral character. But do children necessarily understand the moral message of a narrative? Third and fifth grade students and adults were tested for their ability to apprehend the moral messages in three stories selected from The Book of Virtues and other sources. After listening and reading along with three moral stories, participants were asked to generate the message, select the message from a list of possible messages and select a vignette with the same message from three possible vignettes. Subjects also heard and read a non‐moral story and answered comprehension questions about it. Results indicate a developmental difference in moral theme understanding unexplained by reading comprehension scores alone. 相似文献
