These four studies investigated G. Weary and J. A. Edwards’ (1996) hypothesis that causal uncertainty feelings serve as input to perceivers regarding the adequacy of their causal knowledge and thus determine the amount of processing accorded a given task. Participants worked on a task until they had satisfied an assigned stop rule. In three experiments, high causally uncertain people processed more information under a sufficiency of information rule and less under an enjoyment rule, whereas low causally uncertain people generally did not differentiate between the rules. In the last experiment, low causally uncertain people exhibited a similar pattern to the chronic causally uncertain individuals in the first experiments, but only after their causal uncertainty beliefs and feelings had been primed. 相似文献

At the heart of the most radical proposals in Stuart Kauffman's Investigations is his attempt to show that we find in evolutionary biology some configuration spaces—the sets of possible developments for any given system—that (unlike those in traditional physics of Newtonian, relativistic, and quantum stripes) cannot be completely described in advance. We bring Charles Peirce's work on the philosophy of continuity to bear on the problem and discover, first, that Kauffman's arguments do not succeed; second, that Peirce's metaphysics provide new and sounder arguments for the same propositions; third, that Peirce's rigorous but nonstandard treatment of mathematical continuity shows great promise for modeling the unpredictability and growth we find in evolutionary biology; fourth, that it also strengthens a development only hinted at by biologists thus far—the inevitable involvement of the observer's mind in constituting the objects of science. We close with a logical argument for the surprising relevance of metaphysical hypotheses in the natural sciences and with suggestions for future work that will connect these questions to what Kauffman terms the “narrative stance” in biology. 相似文献

Shopping is not always ‘fun’ and is not always ‘therapeutic’, yet, the negative aspects and motivations for this behaviour have received little attention. Consumers often may be dependent upon shopping activity to satisfy personal needs, such as emotional repair and self‐image, which are far removed from the acquisition and use of products. Not only may this dependence be dysfunctional in that it signals an individual's inability to control their shopping behaviour but also it may be symptomatic of more serious problems, such as compulsive and even addictive shopping. This paper explores this shopping dependence in the context of fashion clothing consumption. Male consumers are considered, with sexual orientation employed as an indicator of behaviour. Data from a survey of 225 homosexual and 225 heterosexual UK males suggest that homosexual males display clothes shopping dependence, and at a level that is significantly stronger than for heterosexuals. Younger males show a greater tendency to display such behaviour, with dependence declining with age for both groups. Managerial and research implications are considered.

Once a face is detected, its retinal image will be continually distorted by changes in eye position, noise, lighting and many other factors. Yet from one moment to the next our perception of a face is stable. Recent advances have indicated there is a mechanism for achieving the continuous perception of a person’s identity that pools across prior and present visual inputs. There is still debate as to whether the perception of face attractiveness is also serially dependent. Here we investigate continuity in the perception of attractiveness using a one back [t?1] effect as a marker of serial dependence. Our results show that face attractiveness is biased towards the attractiveness of the previous face, and that this effect is robust despite changes in viewpoint involving rotations around the yaw axis. However, face attractiveness perception is released from this form of rapid adaption when the previously seen face differed in orientation due to a rotation around the roll axis. 相似文献

When a solid crosses the glass transition, viscous flow sets in and the glass transforms into a supercooled liquid. The glass transition temperature exhibits a heating rate dependence which was previously observed to follow a Vogel–Fulcher–Tammann (VFT) equation. Here we report on a change in the heating rate dependence of the glass transition, determined by the distinct increase in the specific heat capacity, of a metallic glass. We combine standard techniques such as differential scanning calorimetry with recently developed ohmic heating techniques in order to cover seven orders of magnitude in heating rate. Contrary to previous reports, our results show that the change of the glass transition temperature cannot be described by a single VFT equation. Instead we find two distinct regimes which independently follow a VFT expression. 相似文献

Objectives“Fast” (i.e., implicit) processing is relatively automatic; “slow” (i.e., explicit) processing is relatively controlled and can override automatic processing. These different processing types often produce different responses that uniquely predict behaviors. In the present study, we tested if explicit, self-reported symptoms of exercise dependence and an implicit association of exercise as important predicted exercise behaviors and change in problematic exercise attitudes.DesignWe assessed implicit attitudes of exercise importance and self-reported symptoms of exercise dependence at Time 1. Participants reported daily exercise behaviors for approximately one month, and then completed a Time 2 assessment of self-reported exercise dependence symptoms.MethodUndergraduate males and females (Time 1, N = 93; Time 2, N = 74) tracked daily exercise behaviors for one month and completed an Implicit Association Test assessing implicit exercise importance and subscales of the Exercise Dependence Questionnaire (EDQ) assessing exercise dependence symptoms.ResultsImplicit attitudes of exercise importance and Time 1 EDQ scores predicted Time 2 EDQ scores. Further, implicit exercise importance and Time 1 EDQ scores predicted daily exercise intensity while Time 1 EDQ scores predicted the amount of days exercised.ConclusionImplicit and explicit processing appear to uniquely predict exercise behaviors and attitudes. Given that different implicit and explicit processes may drive certain exercise factors (e.g., intensity and frequency, respectively), these behaviors may contribute to different aspects of exercise dependence. 相似文献

Modafinil is a drug licensed for the treatment of narcolepsy and sleep apnea. Recently, modafinil has been reported to be used as a pharmacological cognitive enhancer by healthy individuals with no psychiatric disorders. This paper reports on a study that investigated the effects of modafinil on divergent and convergent thinking tasks of creativity. Sixty‐four healthy male (n = 31) and female (n = 33) volunteers participated in a randomized double‐blind placebo‐controlled parallel group design study. For the convergent thinking tasks, modafinil had no significant main effect on the Group Embedded Figures Task and the Remote Associates Task (RAT). However, a median split analysis showed that modafinil participants low in creativity personality trait had significantly higher RAT scores (Mean [M] = 6.85, SD = 3.39; 95% confidence interval [95% CI]: 5.53–8.2) than those high in creativity personality trait (M = 4.27, SD = 3.0; 95% CI: 2.4–6.0). For the divergent thinking tasks, relative to placebo (M = 1.195, SD = 0.28; 95% CI: 1.0–1.3), modafinil (M = 0.77, SD = 0.37; 95% CI: 0.63–0.92) significantly reduced the performance of flexibility scores and marginally reduced the elaboration scores as measured by the Abbreviated Torrance Test for Adults (ATTA). Overall, participants on modafinil (M = 6.3, SD = 2.6; 95% CI: 5.3–7.4) had significantly lower ATTA scores relative to participants on placebo (M = 9.5, SD = 2.3; 95% CI: 8.6–10.4). These results indicate that modafinil might reduce divergent thinking of creativity in healthy individuals. They suggest that, rather than being a more general cognitive enhancer, modafinil might have negative and subtle effects on creativity. However, the results are from a small‐scale trial, which tested a small number of participants. Therefore, the results need to be interpreted with caution. A replication with a large sample of participants is recommended. 相似文献

This study models “the manager invention”, cardinal skill to face the complex, contradictory, unpredictable socio-organizational reality. The works of Morin (on 1986, 1999, 2001) on the processes of the complex thought and those of Detienne and Vernant (1974), of Frontisi-Ducroux (1975) and Dejours (1993) about the mètis or practice intelligence serve us as theoretical supports, the analysis of contents of managers' narratives of empirical supports. The principles of a complex cognition (dialogical of the contradictory, complementarity of opposite, logic of the inclusive third) support the creative strategies of the managers : guile rather than force, diversion, bypassing, double position, happy medium, oblique speeches. 相似文献

Contrasting beliefs and attitudes held by sharecroppers and their landlord on a fazenda in Northeastern Brazil reveal a tendency to split one another into positively and negatively idealized images. Sharecroppers who ambivalently seek patronage construct good vs. bad landlords/patrons. The landlord, defensive about envy and hostility among sharecroppers, constructs good vs. bad tenants/workers. Theory from the Kleinian school of psychoanalysis concerning envy, splitting, and idealization provides a framework for interpreting ethnographic case materials. 相似文献
