This study investigates the employment contract (temporary vs. permanent) in relation to psychological contract content and fulfilment. The psychological contract includes employees' perceptions of their obligations and their entitlements. We hypothesize that transactional elements constitute a common core that is shared both by temporary and permanent workers. Relational elements are added to this core to show employees' and employers' loyalty, and their intentions to do more than necessary. These elements are more likely to be perceived by permanent workers as compared to temporary workers. Additionally, we suggest that relational elements are difficult to fulfil. Accordingly, we expect lower levels of perceived fulfilment for permanent workers as compared to temporary workers. Based on exchange theory, we furthermore hypothesize that these perceptions follow a similar pattern in how employees report entitlements (i.e., what they receive from the company) and reports of their own obligations (i.e., what they give in return). Results based on a seven-country sample (N permanent = 3354; N temporary = 1980) show that permanent workers as compared to temporary workers perceive more relational entitlements and obligations but a similar level of transactional entitlements and obligations. Thus, these results supported the idea of a layered model. The relationship between contract type and fulfilment of the psychological contract was only partly in line with expectations. Temporary workers reported higher fulfilment of entitlements and transactional obligations, but no difference was found for fulfilment of relational obligations. 相似文献

Learning what from where: Effects of spatial regularity on nonspatial sequence learning and updating
《Quarterly journal of experimental psychology (2006)》2013,66(7):1447-1456
The current study examined the influence of redundant stimulus features on our ability to build and update representations of our environment. We hypothesized that our ability to process redundant spatial features would speed our ability to adapt to changing nonspatial regularities. Using a computerized version of the children's game “rock–paper–scissors”, undergraduates were instructed to win as often as possible against a computer opponent. The computer's plays were repeating sequences of five choices that were presented either with spatial regularity (i.e., “rock” would always appear on the left, “paper” in the middle, and “scissors” on the right) or without spatial regularity (i.e., the items were equally likely to appear in any of the three locations). Once participants learned a sequence, the computer switched to a different sequence without participants being informed that a switch had occurred. Redundant spatial regularity improved a participant's ability both to learn sequences of plays and to update their plays to reflect new computer sequences. Our results suggest that our perceptual system is sensitive to redundant spatial stimulus features and that this information can improve learning and updating. 相似文献

Collective Intelligence (CI) can be formalized as a specific1 computational process through the use of a molecular model of computations and mathematical logic, in terms of interacting information_molecules, which are chaotically or quasi-chaotically displacing and running natural-based inference processes in their own environment. The formal definition of Collective Intelligence as a property of a social structure of beings of any nature is surprisingly short and abstract (which is astonishing) from definitions of Life. The formal definition of Collective Intelligence proposed by the author in the last few years seems to be valid for the whole spectrum of beings, in human social structures to ants in colonies, and even for bacterial colonies. It has recently been found that the CI definition also has an engineering value. The theory of CI can also be used to better understand Evolution because it allows us to locate and relate Life and Intelligence in Evolution. Moreover, this approach presents Evolution as something more complex than can be concluded from Darwinism. Probably the most surprising fact is that a simple extrapolation of the definition of Collective Intelligence brings us to the conclusion that most probably the first elementary Collective Intelligence emerged on Earth in the "chemical soup of primeval molecules," much before Life emerged. Collective Intelligence can be defined with fewer and weaker conditions than Life requires. Perhaps the emergence of that early elementary Collective Intelligence provided the basic momentum to build Life as we now know it. Thus Evolution caused Intelligence to create Life. Our hypothesis is consistent with biochemistry theories that "primeval biochemical molecules" started to interact, "firing" the Collective Intelligence of their "elementary chemical social structure" for survival. This successful action boosted further growth of complexity in that "elementary social structure," which finally resulted in the emergence of "well-defined Life." Furthermore, it provided a self-propagating cycle of growth of individual and collective Intelligence and individual and collective Life. The Collective Intelligence of ants, wolves, humans, and so forth today is only a higher level of Collective Intelligence development. Thus the present Evolution is a computational process of unidentified complexity where Life, Intelligence, and perhaps other as yet undiscovered components play temporary roles. In this paper we provide formalization and a proposed partial proof for this hypothesis. 相似文献

Research on vocal expressions of emotion indicates that persons can identify emotions from voice with relatively high accuracy rates. In addition, fairly consistent vocal profiles for specific emotions have been identified. However, important methodological issues remain to be addressed. In this paper, we address the issue of whether there are individual differences in the manner in which particular emotions may be expressed vocally and whether trained speakers’ portrayals of emotion are in some sense superior to untrained speakers’ portrayals. Consistent support was found for differences across speakers in the manner in which they expressed the same emotions. No accompanying relationship was found between differences in expression and accuracy of identification of those expressions. Little evidence for the superiority of trained speakers was found. Implications of these findings for future studies of vocal expressions of emotion, as well as our understanding of emotions in general, are discussed. 相似文献

The Investment Model (IM; Rusbult, 1980, 1983) has been widely used to study the development and maintenance of romantic relationships. Its components—satisfaction, quality of alternatives, investment size and commitment—are operationalized in the Investment Model Scale (IMS; Rusbult, Martz, &; Agnew, 1998). Given its importance for personal relationships literature, this article presents the adaptation and validation of the IMS to Portugal, and the development and validation of a shorter version, the IMS-S. A confirmatory factor analysis replicates the IMS's original four factors structure. A similar structure was found for the IMS-S. For both versions, results show the instruments to have validity and good reliability. Results are discussed considering the scales’ importance for studying romantic relationships. 相似文献

The present study examined stability and transitions in Transtheoretical stages of change for fruit intake in an adult cohort of 735 individuals not exposed to a planned intervention. Six assessments took place within a four-month period with varying time intervals using electronic questionnaires, measuring fruit intake, stage of change and demographic characteristics. Precontemplation and maintenance were the most stable stages of change, while preparation was the least stable. Longer time intervals showed lower stability, but frequent stage transitions also occurred in shorter time intervals. Seven transition profiles were distinguished. Sequences within transition profiles mostly showed stage transitions to adjacent stages, independent of the interval duration. Differences in fruit intake, age, level of education and ethnicity were found between different transition profiles. Stability rates and most transition sequences largely support the Transtheoretical Model. Results indicating potential deviations from the model, e.g. short-term stage instability and stage transition profiles not in accordance with the Transtheoretical Model are discussed. 相似文献

As a part of a larger cross-cultural investigation (Euroteach) which involves 11 European countries and 2 182 secondary school teachers, two were the aims of the present study: (1) to examine the relationship between job conditions and wellness/health outcomes on a group of 169 Italian secondary school teachers, by using the Job Demand-Control-Support (JDCS) Model (Karasek and Theorell, <citeref rid="bib24">1990</citeref>); (2) to analyse the differences with other European countries in the light of specific cultural differences. Controlling for age and gender, results of hierarchical regression indicated that job control and social support combine in different additive patterns with job demands to explain the well-being outcomes (job satisfaction, emotional exhaustion, depersonalisation, somatic complaints). The predictor's linearity check indicated that the job demands variable is curvilinearly associated both with emotional exhaustion ( p<0.005) and with somatic symptoms ( p<0.01). As compared to the average of the other European countries, on the positive side, the Italian teachers manifest both a higher degree of personal accomplishment and a lesser degree of depersonalisation; on the other hand, they claim a lesser degree of social support and a higher degree of somatic complaints. 相似文献
