"We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable rights, that among these are life, liberty and the pursuit of happiness. That, to secure these rights, governments are instituted among men, deriving their just powers from the consent of the governed." These words from the Preamble to the Declaration of Independence, proclaimed a conviction and announced a challenge for our newly formed nation. Today, they either stir the American heart with pride or generate nostalgia for a time when any truth was self-evident and the right to life was deemed inalienable.  相似文献

Suppose the optimizing consumer only has local information, then what? Obviously, there will be a random element of consumption. The link between the frequency distribution of consumption by person and preference surface is worked out. Under convex preferences there will be a unimodal distribution and conversely. A local optimizing theory of addictive behavior is developed from nonconvex preferences. The resulting bimodal distribution of consumption implies a nonrobust outcome for median voter politics. Such a local optimizing model of addiction is compared with globally optimizing models of addiction.  相似文献

Young adult adoptees and nonadoptees provided retrospective accounts of family relationships from infancy to young adulthood. Adoptive families were portrayed as more cohesive and adaptable than nonadoptive families. Adoptive fathers were recalled as being closer to their children then were nonadoptive fathers in the years preceding adolescence. Within the same time frame, adoptive mothers were drawn in a less hierarchical relation to their children than were other parents. Also, while adoptive males saw themselves as presently unconnected to their adoptive parents, adopted females perceived themselves as more connected to their parents in the present than any other period of time. Openness of communication and acknowledgment of difference in adoptive family formation varied with graphic retrospective accounts. Results were considered in terms of discontinuities between reported observations of adoptive families and adoptees' personal reflections on family developmental history.Received PhD in clinical psychology from the State University of New York at Stony Book. Research interests: adoptive family relations, social attributions of children and their parents.Received M.A. from the University of Guelph, Guelph, Ontario, Canada N1G 2W1. Research interests: development of identity, adoption.Received Ph.D. in social psychology from the University of Toronto.

Eighth graders, 11th graders, and college sophomores wrote open-ended essays that characterized their own approaches to moral reasoning. Their essays were scored for the presence of various themes. Students also responded to three dilemmas from the Defining Issues Test (Rest, 1979). Students then rated their own use of justice and care orientations in moral reasoning, using a previously developed instrument (Ford and Lowery, 1986; Lyons, 1983). Characterizations of moral reasoning became more multifaceted and thorough with grade, and correlated with many traditional measures of moral reasoning. Males and females showed some, but relatively few, differences in characterizing their own moral reasoning, although females tended to respond more thoroughly to the open-ended task. Gender differences, when they occurred, were mostly found on measures that assessed so-called feminine issues or concerns, but not on traditional measures of moral reasoning. Characterizations of moral reasoning clustered into five dimensions, raising questions about the utility of the constructs of justice and care orientations.The first and third authors received financial support from a Ford-Mellon grant made to Carleton College. Results of this study were presented at the 1990 meeting of the Society for Research in Adolescence.Received Ph.D. in Psychology and M.S.E. in Computer and Information Sciences at the University of Pennsylvania, and has research interests in the development of reasoning skills, decision making, and conceptual development.Received Ph.D. in Counseling and Guidance from the University of Wisconsin, Madison, and has research interests in adolescent development and adolescent psychopathology.Received B.A. in Psychology from Carleton College in 1990.

This paper explores the organizational strategies used to represent information about political actors in memory, and it illustrates the usefulness of a specific measure, the adjusted ratio of clustering score (ARC), for inferring memory structure. Assuming the operation of an associative network model, we argue that information about a political actor can be organized along three distinct dimensions: attribute type (differentiating between issue positions and personal attributes), partisanship (differentiating between characteristics typical of Republicans and Democrats), and evaluative type (differentiating between positively and negatively evaluated attributes). The results of a laboratory study indicate that organization along the attribute type dimension was most common, with some evidence of partisan organization. There was no evidence of organization along the evaluative dimension. The implications of the study for understanding individual differences in political reasoning, and the consequences of memory organization strategies, are discussed.  相似文献
