Multiple methods were used to explore the character, contexts, and correlates of generativity among 41 men aged 45–55. Generativity in the role of worker was unrelated to generativity in men’s roles as father, citizen and ‘leisurite’. Individuals who were generative in their work reported greater job satisfaction and subjective career success. These associations were stronger for generativity targeting societal well-being and fellow-workers’ growth than for creative/productive generativity. As some theorists have argued, therefore, nurturant forms of generativity may be more adaptive in mid/late career than other varieties, and more indicative of psychosocial maturity. The status of creativity/productivity within the generativity construct seems problematic. Our findings offer qualified support for McAdams and de St Aubin’s (McAdams, D.P., & de St Aubin, E. (1992). A theory of generativity and its assessment through self-report, behavioral acts, and narrative themes in autobiography. Journal of Personality & Social Psychology, 62 (6), 1003–1015) contention that generativity is expressed differentially in the domains of concern, commitment and action, and that the different relationships of these generativity domains to third variables can be interpreted in meaningful ways. 相似文献

Attention capture by faces 总被引:2,自引:0,他引:2
We report three experiments that investigate whether faces are capable of capturing attention when in competition with other non-face objects. In Experiment 1a participants took longer to decide that an array of objects contained a butterfly target when a face appeared as one of the distracting items than when the face did not appear in the array. This irrelevant face effect was eliminated when the items in the arrays were inverted in Experiment 1b ruling out an explanation based on some low-level image-based properties of the faces. Experiment 2 replicated and extended the results of Experiment 1a. Irrelevant faces once again interfered with search for butterflies but, when the roles of faces and butterflies were reversed, irrelevant butterflies no longer interfered with search for faces. This suggests that the irrelevant face effect is unlikely to have been caused by the relative novelty of the faces or arises because butterflies and faces were the only animate items in the arrays. We conclude that these experiments offer evidence of a stimulus-driven capture of attention by faces. 相似文献

Recent evidence suggests that viewing a static prime object (a hand grasp), can activate action representations that affect the subsequent identification of graspable target objects. The present study explored whether stronger effects on target object identification would occur when the prime object (a hand grasp) was made more action-rich and dynamic. Of additional interest was whether this type of action prime would affect the generation of motor activity normally elicited by the target object. Three experiments demonstrated that grasp observation improved the identification of grasp-congruent target objects relative to grasp-incongruent target objects. We argue from this data that identifying a graspable object includes the processing of its action-related attributes. In addition, grasp observation was shown to influence the motor activity elicited by the target object, demonstrating interplay between action-based and object-based motor coding. 相似文献

The present study examines long-term correlated change in personality traits in old age across a time period of 12 years. Data from the Interdisciplinary Study on Adult Development were used to investigate different aspects of personality change and stability. The sample consisted of 300 adults ranging from 60 to 64 years of age at Time 1. Personality was measured with the NEO Five-Factor Inventory. Longitudinal structural stability, differential stability, change in interindividual differences, mean-level change, and correlated change of the 5 personality traits were examined utilizing structural equation modeling. After having established strict measurement invariance, factor variances in Openness to Experience and Conscientiousness were found to be different across testing occasions, implying variant covariation patterns over time. Stability coefficients were around .70, indicating high but not perfect differential stability. The amount of interindividual differences increased with respect to Openness to Experience and Conscientiousness. Both mean-level change and stability in personality were observed. Eventually, except for Neuroticism, a number of medium effect-sized correlations among changes in personality traits emerged, implying that personality changes share a substantial amount of commonality. 相似文献

AGM-theory, named after its founders Carlos Alchourrón, Peter Gärdenfors and David Makinson, is the leading contemporary paradigm in the theory of belief-revision. The theory is reformulated here so as to deal with the central relational notions ‘J is a contraction of K with respect to A’ and ‘J is a revision of K with respect to A’. The new theory is based on a principal-case analysis of the domains of definition of the three main kinds of theory-change (expansion, contraction and revision). The new theory is stated by means of introduction and elimination rules for the relational notions. In this new setting one can re-examine the relationship between contraction and revision, using the appropriate versions of the so-called Levi and Harper identities. Among the positive results are the following. One can derive the extensionality of contraction and revision, rather than merely postulating it. Moreover, one can demonstrate the existence of revision-functions satisfying a principle of monotonicity. The full set of AGM-postulates for revision-functions allow for completely bizarre revisions. This motivates a Principle of Minimal Bloating, which needs to be stated as a separate postulate for revision. Moreover, contractions obtained in the usual way from the bizarre revisions, by using the Harper identity, satisfy Recovery. This provides a new reason (in addition to several others already adduced in the literature) for thinking that the contraction postulate of Recovery fails to capture the Principle of Minimal Mutilation. So the search is still on for a proper explication of the notion of minimal mutilation, to do service in both the theory of contraction and the theory of revision. The new relational formulation of AGM-theory, based on principal-case analysis, shares with the original, functional form of AGM-theory the idealizing assumption that the belief-sets of rational agents are to be modelled as consistent, logically closed sets of sentences. The upshot of the results presented here is that the new relational theory does a better job of making important matters clear than does the original functional theory. A new setting has been provided within which one can profitably address two pressing questions for AGM-theory: (1) how is the notion of minimal mutilation (by both contractions and revisions) best analyzed? and (2) how is one to rule out unnecessary bloating by revisions? 相似文献

We examine in detail three classic reasoning fallacies, that is, supposedly ``incorrect' forms of argument. These are the so-called argumentam ad ignorantiam, the circular argument or petitio principii, and the slippery slope argument. In each case, the argument type is shown to match structurally arguments which are widely accepted. This suggests that it is not the form of the arguments as such that is problematic but rather something about the content of those examples with which they are typically justified. This leads to a Bayesian reanalysis of these classic argument forms and a reformulation of the conditions under which they do or do not constitute legitimate forms of argumentation. 相似文献

There is a persisting tendency in attempts to define spirituality, to adopt a dualistic point of view which sees the spirit as somehow impenetrably inner, innate and introspectively perceived, interacting with the outer world through the body. As well as a strong intuitive sense of the correctness of this philosophical point of view, it also is supported by psychotherapeutic perspectives that speak of the private inner being. In this paper I will argue that this view is logically, epistemologically, morally, and psychologically problematic. It will be argued that the concept of an inwardness to our mental life can be distinguished from the view of that life as interior. The perspective that we have of our inward selves is learned and conditional upon a sense of an outer self, functioning and communicating in the public world. Rather than an ego centric conceptualization of spirituality based on the idea of the spirit as inner and logically inaccessible, I we might adopt a sociocentric perspective in which the supremacy of the ego is dissolved in favour of an understanding in which we see ourselves as part of the social and natural outer world in which we exist. 相似文献

An expression-induction model was used to simulate the evolution of basic color terms to test Berlin and Kay's (1969) hypothesis that the typological patterns observed in basic color term systems are produced by a process of cultural evolution under the influence of biases resulting from the special properties of universal focal colors. Ten agents were simulated, each of which could learn color term denotations by generalizing from examples using Bayesian inference, and for which universal focal red, yellow, green, and blue were especially salient, but unevenly spaced in the perceptual color space. Conversations between these agents, in which agents would learn from one another, were simulated over several generations, and the languages emerging at the end of each simulation were investigated. The proportion of color terms of each type correlated closely with the equivalent frequencies found in the World Color Survey, and most of the emergent languages could be placed on one of the evolutionary trajectories proposed by Kay and Maffi (1999). The simulation therefore demonstrates how typological patterns can emerge as a result of learning biases acting over a period of time. 相似文献

The Posttraumatic Cognitions Inventory (PTCI) assesses cognitions hypothesised to be associated with poor recovery from traumatic experiences and the maintenance of PTSD. The validity of the PTCI has received good support but doubts have been raised about its Self-BLAME subscale. The main aim of the present study was to test the ability of the PTCI subscales to discriminate between traumatised individuals with and without PTSD and to predict posttraumatic symptom severity. Participants (N=63) who had experienced a traumatic event were recruited via the media and completed the PTCI and self-report measures of PTSD and depression symptoms. Full criteria for a diagnosis of PTSD were met by 37 but not by the other 26. There were significant differences between these two groups on the total PTCI score and the Negative Cognitions About SELF and the Negative Cognitions About the WORLD subscales, but not on the Self-BLAME subscale. The two groups were discriminated by the PTCI subscales with 65% accuracy and the multiple correlation (R=.68) between the subscales and posttraumatic symptom severity was highly significant. However, in these analyses, higher scores on the Self-BLAME subscale were associated with less risk of a diagnosis of PTSD and with less posttraumatic symptomatology. Possible interpretations of these results, in terms of statistical suppressor effects and the protective role of behavioural self-blame, are discussed. 相似文献
