The sources of individual differences in human and nonhuman animals remain controversial. We demonstrate that diet and genetics interact in determining the ontogenetic trajectory of chemosensory and prey preferences in the common garter snake, Thamnophis sirtalis , a dietary generalist. In litters of neonate snakes from a single small field in an earthworm-ingesting population, initial responses to chemical cues from fish and worm were similar, with zero heritabilities. After 12 meals on fish, however, the heritability of both fish and worm chemosensory responses increased markedly, the change in response to fish but not worm chemicals was heritable, the relative preference for fish versus worm was heritable, and the change in relative preference was heritable. In addition, growth rates on each diet were related to changes in chemoreceptive responses. Such genetic-environment variation that emerges only after equivalent ontogenetic experience may be a factor in responses to environmental change in many species. 相似文献

Interpersonal relatedness,self-definition,and their motivational orientation during adolescence: a theoretical and empirical integration 总被引:4,自引:0,他引:4
The authors examined a theoretical model linking interpersonal relatedness and self-definition (S.J. Blatt, 1974), autonomous and controlled regulation (E. L. Deci & R. M. Ryan, 1985), and negative and positive life events in adolescence (N = 860). They hypothesized that motivational orientation would mediate the effects of interpersonal relatedness and self-definition on life events. Self-criticism, a maladaptive form of self-definition, predicted less positive events, whereas efficacy, an adaptive form of self-definition, predicted more positive events. These effects were fully mediated by the absence and presence, respectively, of autonomous motivation. Controlled motivation, predicted by self-criticism and maladaptive neediness, did not predict negative events. Results illustrate the centrality of protective, pleasure-related processes in adaptive adolescent development. 相似文献

In a time of rapid technological and social change, business organizations must help their employees develop a new appreciation of how social and ethical values are being shaped and challenged by evolving information technologies. Many ethical and social conflicts have arisen around the advanced information technology used today. The emerging technologies continue to create situations not previously encountered. There are numerous risks facing corporations involved in the use of computing technology. Leaders of organizations looking ahead to assess the impact of technological changes can try to prepare their employees for the future. This paper addresses the urgent need for individuals in corporations to become more knowledgeable about computing technologies and their impact. 相似文献

Most Danish youth participate in the traditional Lutheran ritual of confirmation. However, a growing minority does not. Based on survey data collected in 2011 from over 600 Danish pupils, this study examines the ways in which Danish ‘nonfirmands’ are different from their peers who participate in confirmation in relation to religious background, personal religious beliefs, intellectual engagement, and demographic factors. We further explore key motivations for ‘nonfirmation’ expressed by the nonfirmands in the sample. Broadly speaking, our findings highlight secular socialization and individual beliefs about God as key elements in understanding the nonfirmand and his or her reasons for opting out of confirmation. We expect confirmations to continue to decline in popularity as nonfirmation gains social acceptance, as nonfirmands raise their own children, and as Denmark becomes increasingly secular. 相似文献

Previous experiments have demonstrated that exposure to faces can change the perception of normality in new faces, such that faces similar to those at exposure appear more normal. Here we examined how experience influences adaptation effects in African Hadza hunter-gatherers, who have limited experience with White faces. We exposed participants to sets of either Hadza or White European faces that were manipulated to possess either wide-spaced or narrow-spaced eyes. We collected normality judgments both pre-exposure and post-exposure by showing pairs of images, one with wide-spaced and one with narrow-spaced eyes. Examining the difference between the pre-exposure and post-exposure judgments revealed that participants selected an increased number of images that were congruent with the faces to which they had been exposed. The change in normality judgments was strongest for White faces, suggesting that representations of White ethnicity faces are more malleable and less robust to adaptation, potentially because of the decreased experience that individuals had with them. A second experiment using the same test stimuli with a sample of White participants revealed equivalent adaptation effects for both Hadza and White faces. These data highlight the role of experience on the high-level visual adaptation of faces. 相似文献

Average faces possess traits that are common to a population. Preferences for averageness have been found in several types of study of both real and computer-manipulated faces. Such preferences have been proposed to be biologically based and thus should be found across human populations, though cross-cultural evidence to date has been limited. In this study we examined preferences for averageness in both the West and in an isolated hunter-gatherer society, the Hadza of Northern Tanzania in Africa. We show that averageness is generally preferred across faces and cultures, but there were no significant preferences for averageness in European faces by Hadza judges. The different visual experience of the two cultures may explain the differences in preferences. While Westerners have visual experience of both European and African faces, the Hadza are limited in their experience of European faces, potentially leading to a lack of preference for averageness in this group because of the lack of a representation of the 'norm' of European faces. 相似文献

Illness narratives from patients with colorectal cancer commonly record patterns of change in social relationships that follow the diagnosis and treatment of the condition. We believe that these changes are best explained as a process of facework, which reflects losses of face on the part of the patient, and which assists in the creation of new faces that convey new senses of identity. Facework is familiar in the work by E. Goffman (1955) and has been extensively reworked since his time. There is considerable agreement that face is a pervasive and universal constituent of all social interaction, and that it expresses the subject's view of the way he or she would like to be considered by others in interactions. Ho's concept of multiple faces negotiated dynamically according to social context is particularly useful in understanding the purpose and techniques of facework (D. Y.-F. Ho, 1994). We propose a model of face that uses dignity as the face-expression of personal attributes and acquisitions, and honor as the face-expression of systemic capabilities and attainments. This model can be used to examine individual variations in response and adaptation to colon cancer and its treatment, and it provides a useful means of teaching health care workers about the experience of illness. 相似文献

Abstract Integrating multi-axial models with an action-theory perspective, we propose that children's coping strategies vary along four dimensions of strategic behavioral control: Direct Action, Indirect Action, Prosocial Action, and Antisocial Action. The Behavioral Inventory of Strategic Control (BISC) assesses these four general dimensions of strategic control. We contrast these four axial dimensions with six specific strategic combinations: Avoidance (Indirect-Antisocial), Emotional Support Seeking (Indirect-Prosocial), Social Exploitation (Indirect-Antisocial), Social Cooperation (Direct-Prosocial), Aggressive Individualism (Direct-Antisocial) and Hostility (Indirect-Antisocial). In a short-term longitudinal study (three occasions over four months) of 318 children (grades 2–6), we examined the validity of the BISC, showing that the hypothesized dimensional structure of children's strategic control behavior was strongly supported. 相似文献
