Torsion creep experiments are carried out in order to understand the physics of ice plasticity. A dislocation spreading mechanism based on double cross-slip of basal dislocations is proposed to explain the strong plastic anisotropy and the power law relationship between stress and strain rates. The scenario is tested using three-dimensional dislocation dynamics simulations. Numerical investigations give a stress exponent n?=?2.3 in agreement with experimental measurements. This dislocation spreading mechanism sheds a new light on the interpretation of former experimental observations. 相似文献

The main goal of the current research is to investigate emotional reactions to situations that implicate honour in Turkish and northern American cultural groups. In Studies 1A and 1B, participants rated the degree to which a variety of events fit their prototypes for honour-related situations. Both Turkish and American participants evaluated situations generated by their co-nationals as most central to their prototypes of honour-related situations. Study 2 examined emotional responses to Turkish or US-generated situations that varied in centrality to the prototype. Highly central situations and Turkish-generated situations elicited stronger emotions than less central situations and US-generated situations. Americans reported higher levels of positive emotions in response to honour-enhancing situations than did Turkish participants. These findings demonstrate that the prototypes of honour relevant situations differ for Turkish and northern American people, and that Turkish honour relevant situations are more emotion-laden than are northern American honour relevant situations. 相似文献

ABSTRACTThe animacy effect refers to enhanced memory for animate over inanimate items. In two studies, we examined whether this memory advantage generalises to source memory. A multinomial processing tree model was used to disentangle item recognition, source memory, and guessing processes. In Study 1, animate and inanimate words were presented at different spatial locations on the screen. Animacy was associated with enhanced source memory for the spatial locations of the items. In Study 2, pseudowords were associated with animate and inanimate properties. Replicating previous results, the pseudowords were better remembered when they were associated with animate properties than when they were associated with inanimate properties. What is more, participants had enhanced source memory for the association between the pseudowords and the animate properties. The results strengthen the idea that animate items are associated with richer mnemonic representations than inanimate items. 相似文献

The utterance of a negative statement invites the pragmatic inference that some reason exists for the proposition it negates to be true; this pragmatic inference paves the way for the logically unexpected Modus Shmollens inference: “If p then q; not-q; therefore, p.” Experiment 1 shows that a majority of reasoners endorse Modus Shmollens from an explicit major conditional premise and a negative utterance as a minor premise: e.g., reasoners conclude that “the soup tastes like garlic” from the premises “If a soup tastes like garlic, then there is garlic in the soup; Carole tells Didier that there is no garlic in the soup they are eating.” Experiment 2 shows that this effect is mediated by the derivation of a pragmatic inference from negation. We discuss how theories of conditional reasoning can integrate such a pragmatic effect. 相似文献

There is a wide agreement that emotions are central to the evaluation and understanding of change processes in psychotherapy. Unfortunately, most of the debate on the role of emotions has been influenced by the reductionist view of ‘psychophysiological symbolism’ (Averill 1996). We defend the position that, in order to understand their role in psychotherapy fully, we need to move in the direction of a more complex view of emotions. This paper presents a view of emotionsas social constructed phenomena operating via language and narrative. We present research suggesting that these narratives may be an essential process for understanding psychological disorders, how these disorders are developed and, finally, how they can be changed. 相似文献

We studied variables influencing category and letter fluency in a large population-based sample of elderly participants. Letter and category fluency tasks were administered to 1133 unselected non-demented elderly participants in the Paquid cohort on normal and pathological aging. Age, education, principal lifetime occupation and depressive symptomatology independently influenced both category and letter fluency, while gender influenced only category fluency. A conceptualization measure (similarities) was found to influence fluency results mostly through education and prior occupation. 相似文献

Abstract Theories of personal identity purport to specify truth conditions for sentences of the form ‘x‐at‐ti is the same person as y‐at‐tj. Most philosophers nowadays agree that such truth conditions are to be stated in terms of psychological continuity. However; opinions vary as to how the notion of psychological continuity is to be understood. In a recent contribution to this journal, Slors offers an account in which psychological continuity is spelled out in terms of narrative connectedness between mental states.The present paper argues that Slors’ theory either is no theory of personal identity at all or is too weak.Towards the end of the paper, it is indicated how the problem uncovered for Slors’ theory may be avoided. 相似文献

The current study examined skills of cognitive flexibility and sustained attention in late bilingual and monolingual younger adults. One-hundred and sixty two younger adults aged between 18 and 34 years old (M = 22.39) classified as Turkish-English late bilinguals (N = 74) and Turkish monolinguals (N = 88) completed the Trail Making Test (TMT-A and TMT-B). Results from this study showed that Turkish-English late bilinguals had shorter RTs than Turkish monolinguals on the TMT-B, however there were no significant RT differences between the groups on the TMT-A. These findings indicate that bilingualism impacts upon skills of cognitive flexibility but not sustained attention and that the amount of practice in coordinating, monitoring, and switching between languages is an important determinant of cognitive improvement. 相似文献

The present research applies a self‐determination theory framework to capture the broad spectrum of reasons why individuals engage in harmful normative behaviors. This correlational study (N = 242) focused on harmful behaviors that were either supported by one's in‐group or not. Participants whose in‐group encourages them to engage in a harmful behavior reported stronger motivation, both self‐determined and non‐self‐determined. Perceiving strong in‐group norms in favor of these behaviors was associated positively with the non‐self‐determined motivation pertaining to introjected regulation. The more participants agreed with an in‐group norm in favor of a harmful behavior, the stronger their self‐determination for engaging in this behavior. Results are discussed in light of self‐determination theory, normative models of social influence, and intergroup theories. 相似文献
