ABSTRACTLiterature provides mixed results on the effect of participatory practices on outcomes such as individual performance and job stressors. By examining these relationships via the mediation of job crafting behaviors, while considering the moderating effect of autonomy, we help clarifying the reasons behind the apparently ambiguous effects of participation. We surveyed 318 employees in an Italian mass retail company. On the one hand, we found a positive effect of participation on performance and a reduction of both role conflict and role overload thanks to increased job crafting behaviors aimed at seeking job resources. On the other hand, we also found that participation and autonomy may augment job stressors because of an associated increase of job crafting behaviors aimed at seeking challenging demands. 相似文献

Argumentation schemes are forms of reasoning that are fallible but correctable within a self-correcting framework. Their use provides a basis for taking rational action or for reasonably accepting a conclusion as a tentative hypothesis, but they are not deductively valid. We argue that teleological reasoning can provide the basis for justifying the use of argument schemes both in monological and dialogical reasoning. We consider how such a teleological justification, besides being inspired by the aim of directing a bounded cognizer to true belief and correct choices, needs to take into account the attitudes of dialogue partners as well as normative models of dialogue and communicative activity types, in particular social and cultural settings. 相似文献

Background
Tourette syndrome (TS) is characterized by dysfunctional connectivity between prefrontal cortex and sub-cortical structures, and altered meso-cortical and/or meso-striatal dopamine release. Since time processing is also regulated by fronto-striatal circuits and modulated by dopaminergic transmission, we hypothesized that time processing is abnormal in TS.Methods
We compared time processing abilities between nine children with TS-only (i.e. without major psychiatric comorbidities) and 10 age-matched healthy children, employing a time reproduction task in which subjects actively reproduce different temporal intervals, and a time comparison task in which subjects judge whether a test interval is longer or shorter than a reference interval. IQ, sustained and divided attention, and working memory were assessed in both groups using the Leiter International Performance Scale-Revised, and the Digit Span sub-test of the WISC-R.Results
Children with TS-only reproduced in an overestimated fashion over-second, but not sub-second, time intervals. The precision of over-second intervals reproduction correlated with tic severity, in that the lower the tic severity, the closer the reproduction of over-second time intervals to their real duration. Time reproduction performance did not significantly correlate with IQ, attention and working memory measures in both groups. No differences between groups were documented in the time comparison task.Conclusions
The improvement of time processing in children with TS-only seems specific for the over-second range of intervals, consistent with an enhancement in the ‘cognitively controlled’ timing system, which mainly processes longer duration intervals, and depends upon dysfunctional connectivity between the basal ganglia and the dorso-lateral prefrontal cortex. The absence of between-group differences on time comparison, moreover, suggests that TS patients manifest a selective improvement of ‘motor’ timing abilities, rather than of perceptual time abilities. Our data also support an enhancement of cognitive control processes in TS children, probably facilitated by effortful tic suppression. 相似文献154.

Writing processes have been studied extensively from the cognitive point of view, but little attention has been given to the affective aspects of this activity. In fact, writing experience seems to be relevant to a person not only because it is a complex cognitive activity, but also because it often has an affective characterization. The aim of the present study was to investigate writing as a meaningful activity, that is, to analyze the way in which pupils of different grade levels construe this activity. The study was divided into two phases: (a) interviews with pupils in order to select relevant elements (i.e., writing situations and contexts) and (b) subjects' elicitation of constructs and evaluation of elements. From the qualitative and quantitative analyses of the grids, a developmental trend emerged. Whereas the younger subjects frequently elicited constructs related to the affective dimension of writing, as age increased, the cognitive dimension became more evident. 相似文献

We present a compositional semantics for first-order logic with imperfect information that is equivalent to Sevenster and Sandu’s equilibrium semantics (under which the truth value of a sentence in a finite model is equal to the minimax value of its semantic game). Our semantics is a generalization of an earlier semantics developed by the first author that was based on behavioral strategies, rather than mixed strategies. 相似文献

High levels of perfectionism have been observed in major depression, anxiety disorders and eating disorders. Though few studies have compared levels of perfectionism across these disorders, there is reason to believe that different dimensions of perfectionism may be involved in eating disorders than in depression or anxiety [Bardone-Cone, A. M. et al. (2007). Perfectionism and eating disorders: Current status and future directions. Clinical Psychology Review, 27, 84-405]. The present study compared patients with major depression, obsessive-compulsive disorder, and eating disorders on dimensions of perfectionism. Concern over Mistakes was elevated in each of the patient groups while Pure Personal Standards was only elevated in the eating disorder sample. Doubts about Actions was elevated in both patients with obsessive-compulsive disorder and eating disorders, but not in depressed patients. Analyses of covariance indicated that Concern over Mistakes accounted for most of the variance in the relationship of perfectionism to these forms of psychopathology. 相似文献

Recent neurophysiological and brain imaging studies have shown that the motor system is involved in language processing. However, it is an open question whether this involvement is a necessary requisite to understand language or rather a side effect of distinct cognitive processes underlying it. In order to clarify this issue we carried out three behavioral experiments, using a go-no go paradigm. Italian verbs expressing hand actions, foot actions or an abstract content served as stimuli. Participants used their right hands to respond. In Experiment 1, in which a semantics decision task with an early delivery of the go signal (during processing language material) was used, slower responses were found for hand action-related verbs than for foot action-related verbs. In Experiment 2, using the same task with either an early or a delayed delivery of the go signal (when language material had been already processed), no difference was found between responses to the two verb categories in the delayed delivery condition. In Experiment 3, in which a lexical decision task with an early delivery of the go signal was used, again no difference between the two verb categories was found. The present findings demonstrate that during language processing the modulation of the motor system crucially occurs while performing a semantics decision task, thus supporting the notion that this involvement is a necessary step to understand language rather than a side effect of upstream cognitive processes. 相似文献
