Using social exchange theory, we argue that because supervisors tend to value employee trustworthiness, they will be more likely to adhere to interpersonal and informational justice rules with trustworthy employees. Given social exchange theory’s assumption that benefits are voluntary in nature, we propose that the benevolence and integrity facets of trustworthiness will be more likely to engender social exchange relationships than the ability facet. Specifically, we propose that employees seen as having high benevolence and integrity engender feelings of obligation and trust from their direct supervisors, increasing the likelihood that these supervisors will adhere to interpersonal and informational justice rules, which in turn influences employee perceptions of justice. We find partial support for our mediated model using a field sample. 相似文献

This article presents an historical and conceptual overview on different approaches to logical abstraction. Two main trends concerning abstraction in the history of logic are highlighted, starting from the logical notions of concept and function. This analysis strictly relates to the philosophical discussion on the nature of abstract objects. I develop this issue further with respect to the procedure of abstraction involved by (typed) λ-systems, focusing on the crucial change about meaning and predicability. In particular, the analysis of the nature of logical types in the context of Constructive Type Theory allows elucidation of the role of the previously introduced notions. Finally, the connection to the analysis of abstraction in computer science is drawn, and the methodological contribution provided by the notion of information is considered, showing its conceptual and technical relevance. Future research shall focus on the notion of information in distributed systems, analysing the paradigm of information hiding in dependent type theories. 相似文献

In this paper I shall reply to two arguments that Stephen Stich (1990; 1991; 1996) has recently put forward against the thesis of eliminative materialism. In a nutshell, Stich argues that (i) the thesis of eliminative materialism, according to which propositional attitudes don't exist, is neither true nor false, and that (ii) even if it were true, that would be philosophically uninteresting. To support (i) and (ii) Stich relies on two premises: (a) that the job of a theory of reference is to make explicit the tacit theory of reference which underlies our intuitions about the notion of reference itself; and (b) that our intuitive notion of reference is a highly idiosyncratic one. In this paper I shall address Stich's anti-eliminativist claims (i) and (ii). I shall argue that even if we agreed with premises (a) and (b), that would lend no support whatsoever to (i) and (ii). 相似文献

In this paper I take up Dana Amir's concept of the “chameleon language” of perversion considering Wittgenstein's idea of the language-game and the necessity of taking up the context of communication. The setting of psychoanalysis represents a new context for the language of perversion, one that at first implicitly and later explicitly recognizes the bid for tenderness beneath the stealth. I suggest it is the analyst's willingness to risk vulnerability in this game, as much as the interpretation of perverse pacts, that fosters clinical change. 相似文献

Working memory deficits in transgenic rats overexpressing human adenosine A2A receptors in the brain

Adenosine receptors in the central nervous system have been implicated in the modulation of different behavioural patterns and cognitive functions although the specific role of A(2A) receptor (A(2A)R) subtype in learning and memory is still unclear. In the present work we establish a novel transgenic rat strain, TGR(NSEhA2A), overexpressing adenosine A(2A)Rs mainly in the cerebral cortex, the hippocampal formation, and the cerebellum. Thereafter, we explore the relevance of this A(2A)Rs overexpression for learning and memory function. Animals were behaviourally assessed in several learning and memory tasks (6-arms radial tunnel maze, T-maze, object recognition, and several Morris water maze paradigms) and other tests for spontaneous motor activity (open field, hexagonal tunnel maze) and anxiety (plus maze) as modification of these behaviours may interfere with the assessment of cognitive function. Neither motor performance and emotional/anxious-like behaviours were altered by overexpression of A(2A)Rs. TGR(NSEhA2A) showed normal hippocampal-dependent learning of spatial reference memory. However, they presented working memory deficits as detected by performance of constant errors in the blind arms of the 6 arm radial tunnel maze, reduced recognition of a novel object and a lack of learning improvement over four trials on the same day which was not observed over consecutive days in a repeated acquisition paradigm in the Morris water maze. Given the interdependence between adenosinic and dopaminergic function, the present results render the novel TGR(NSEhA2A) as a putative animal model for the working memory deficits and cognitive disruptions related to overstimulation of cortical A(2A)Rs or to dopaminergic prefrontal dysfunction as seen in schizophrenic or Parkinson's disease patients. 相似文献

Conditioned suppression is a useful technique for assessing whether subjects have learned a CS-US association, but it is difficult to use in humans because of the need for an aversive US. The purpose of this research was to develop a non-aversive procedure that would produce suppression. Subjects learned to press the space bar of a computer as part of a video game, but they had to stop pressing whenever a visual US appeared, or they would lose points. In Experiment 1, we used an A+/B- discrimination design: The US always followed Stimulus A and never followed Stimulus B. Although no information about the existence of CSs was given to the subjects, suppression ratio results showed a discrimination learning curve-that is, subjects learned to suppress responding in anticipation of the US when Stimulus A was present but not during the presentations of Stimulus B. Experiment 2 explored the potential of this preparation by using two different instruction sets and assessing post-experimental judgements of CS A and CS B in addition to suppression ratios. The results of these experiments suggest that conditioned suppression can be reliably and conveniently used in the human laboratory, providing a bridge between experiments on animal conditioning and experiments on human judgements of causality. 相似文献

The publication of Otto Rank's The Trauma of Birth (1924) gave rise to an intense debate within the secret Committee and confronted Freud with one of his most beloved disciples. After analyzing the letters that the Professor exchanged with his closest collaborators and reviewing the works he published during this period, it is clear that anxiety was a crucial element among the topics in dispute. His reflections linked to the signal anxiety concept allowed Freud to refute Rank's thesis that defined birth trauma as the paradigmatic key to understanding neurosis, and, in turn, was a way of confirming the validity of the concepts of Oedipus complex, repression and castration in the conceptualization of anxiety. The reasons for the modifications of anxiety theory in the mid-1920s cannot be reduced, as Freud would affirm officially in his work of 1926, to the detection of internal contradictions in his theory or to the desire to establish a metapsychological version of the problem, for they gain their essential impulse from the debate with Rank. 相似文献

Lewis rats have been shown to make more impulsive choices than Fischer 344 rats in discrete-trial choice procedures that arrange fixed (i.e., nontitrating) reinforcement parameters. However, nontitrating procedures yield only gross estimates of preference, as choice measures in animal subjects are rarely graded at the level of the individual subject. The present study was designed to examine potential strain differences in delay discounting using an adjusting-amount procedure, in which distributed (rather than exclusive) choice is observed due to dynamic titration of reinforcer magnitude across trials. Using a steady-state version of the adjusting-amount procedure in which delay was manipulated between experimental conditions, steeper delay discounting was observed in Lewis rats compared to Fischer 344 rats; further, delay discounting in both strains was well described by the traditional hyperbolic discounting model. However, upon partial completion of the present study, a study published elsewhere (Wilhelm & Mitchell, 2009) demonstrated no difference in delay discounting between these strains with the use of a more rapid version of the adjusting-amount procedure (i.e., in which delay is manipulated daily). Thus, following completion of the steady-state assessment in the present study, all surviving Lewis and Fischer 344 rats completed an approximation of this rapid-determination procedure in which no strain difference in delay discounting was observed. 相似文献

This research examines the internal consistency, convergent validity, and sensitivity, specificity, and positive and negative predictive value of the Spanish version of the Eating Disorder Examination-Self-Report Questionnaire (S-EDE-Q), as a screening questionnaire for eating disorders (ED) in a community sample. Participants were 1543 male and female Spanish-speaking students (age range: 12-21 years), who volunteered to complete the S-EDE-Q and the EAT-40. The Spanish version of the Eating Disorders Examination (S-EDE) interview, 12th edition, was administered to 602 of the students. Acceptable internal consistency for the four subscales of the S-EDE-Q was obtained (alpha > or = .74). Corrected point-biserial correlation performed with the 22 items included in the S-EDE-Q subscales showed acceptable values for all the items. The EAT-40 Dieting subscale correlated highly and positively with the four S-EDE-Q subscales (r > or = .70). Acceptable results in sensitivity, specificity, and positive and negative predictive value when compared with the EDE were found. Correlation between S-EDE and S-EDE-Q diagnoses was positive and significant. Overall, results support the psychometric adequacy of the S-EDE-Q as a screening questionnaire for ED in community samples. 相似文献
