Evidence is presented for the immediate apprehension of exact small quantities. Participants performed a quantification task (are the number of items greater or smaller than?), and carry-over effects were examined between numbers requiring the same response. Carry-over effects between small numbers were strongly affected by repeats of pattern and number identity relative to when displays were from the same response category but contained different numbers. Carry-over effects with large items were less sensitive to both pattern and number identity, even when the numbers in the small and large categories were matched for discriminability. The data suggest that small numbers are immediately apprehended through a direct subitization process distinct from pattern recognition and the apprehension of approximate number.  相似文献

The primary aim of the present 1-year longitudinal study among university employees (N = 1314) was to investigate individual development of perceived employability (PE) by utilizing a person-centred approach. Thus, we identified latent classes of PE across 1 year based on growth mixture modelling. In addition, the latent classes were characterized by perceived job insecurity and the type of employment contract and its changes over the 1-year time period. The results showed four latent classes of PE that differed in the level and the direction of mean-level changes over time. These latent classes were: (1) stable relatively high PE (n = 641); (2) unstable decreasing PE (n = 45); (3) unstable increasing PE (n = 24); and (4) stable relatively low PE (n = 603). Perceived job insecurity associated with the latent class membership of PE. That is, low levels of perceived job insecurity were associated with favourable PE classes (i.e., “stable relatively high” and “unstable increasing employability”), whereas high levels of job insecurity associated with unfavourable PE classes (i.e., “stable relatively low” and “unstable decreasing employability”). Furthermore, transitions from temporary to permanent job contract occurred more often in the favourable than in unfavourable PE classes, but transitions from permanent to temporary contract were more likely in the unfavourable classes. Thus, our study indicated a substantial amount of heterogeneity in the development of PE across 1 year.  相似文献

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

Multiple instruments have been developed and used to measure quantitative job insecurity (i.e., insecurity to lose the job as such), often without systematic evaluation of their psychometric characteristics across countries and language barriers. This may hamper consistent and reliable cross-study and cross-country comparisons. This study's aim was to introduce and validate the four-item Job Insecurity Scale (JIS) developed by De Witte across five European countries (i.e., Belgium, The Netherlands, Spain, Sweden, and the UK). Overall, the results demonstrated the construct validity (i.e., configural invariance and invariance of the measurement model parameters), the reliability (internal consistency of the items), and the criterion validity (with respect to affective organizational commitment, perceived general health, and self-reported performance) of the JIS. The different translations of the JIS can thus be considered as valid and reliable instruments to measure job insecurity and can be used to make meaningful comparisons across countries. Furthermore, the JIS translations may be utilized to assess how job insecurity is related to outcomes.  相似文献

This study discusses the impact of stress specific to being lesbian, gay, or bisexual (LGB)—measured by means of the concepts of stigma consciousness and internalized homonegativity—on the mental well-being of LGB youth. Also, the effects of positive and negative social support were considered within the model. The sample consisted of 743 LGBs less than 26 years old who were recruited during the online ZZZIP survey in Flanders, Belgium. Hierarchical regression shows that LGB-specific unsupportive social interactions have the greatest direct effect on mental well-being of LGB youth, followed respectively by stigma consciousness, internalized homonegativity, and confidant support.  相似文献

Neuropsychological tests of visual perception mostly assess high‐level processes like object recognition. Object recognition, however, relies on distinct mid‐level processes of perceptual organization that are only implicitly tested in classical tests. Furthermore, the psychometric properties of the existing instruments are limited. To fill this gap, the Leuven perceptual organization screening test (L‐POST) was developed, in which a wide range of mid‐level phenomena are measured in 15 subtests. In this study, we evaluated reliability and validity of the L‐POST. Performance on the test is evaluated relative to a norm sample of more than 1,500 healthy control participants. Cronbach's alpha of the norm sample and test–retest correlations for 20 patients provide evidence for adequate reliability of L‐POST performance. The convergent and discriminant validity of the test was assessed in 40 brain‐damaged patients, whose performance on the L‐POST was compared with standard clinical tests of visual perception and other measures of cognitive function. The L‐POST showed high sensitivity to visual dysfunction and decreased performance was specific to visual problems. In conclusion, the L‐POST is a reliable and valid screening test for perceptual organization. It offers a useful online tool for researchers and clinicians to get a broader overview of the mid‐level processes that are preserved or disrupted in a given patient.  相似文献

This study probes the relationship between perceived external employability (i.e., the individual’s perception of available jobs on the external labour market) and affective commitment and performance within the framework of social exchange. An innovative feature is that we advance perceived external employability as a commodity of interdependent forward-looking exchange: employees who perceive themselves as externally employable anticipate successful exchange, which drives further responses, both relational (i.e., affective organizational commitment) and behavioural (i.e., performance). Strong features of this study are that we include (a) both the organization and the workgroup as foci of affective commitment, and (b) task, helping, and counterproductive behaviour as indicators of performance. Results from cross-lagged, structural equation modelling (SEM) analyses on two-wave survey data (= 458 Belgian employees) largely align with our idea: perceived external employability has a positive cross-lagged effect on affective organizational and workgroup commitment. The two foci of commitment in turn have a cross-lagged effect on performance, positive in the case of helping behaviour and negative in the case of counterproductive behaviour. No significant cross-lagged effects were found in relation to task behaviour. We discuss these results in the light of Social Exchange Theory and potential routes for future research.  相似文献

Oculomotor bias induced by number perception   总被引:9,自引:0,他引:9  
Previous research with manual response methods has found evidence for an association between numbers and space. The present study investigated whether eye movements also show this association. Eye movement responses were recorded from 15 healthy participants as they categorized the digits 0-9 as odd or even. Responses were initiated faster to the left in response to small digits and faster to the right in response to large digits. Movement amplitudes were not systematically affected by either number magnitude or parity. These results provide further evidence for a spatially oriented "mental number line".  相似文献

A balanced time perspective can help retaining or improving happiness. Research shows shifts in time perspective while ageing. In order to reach a better understanding of the value of time perspective in different age groups, results are reported of a survey (n = 525), which examines the moderating role of age in the association between time perspective and happiness. Time perspective was measured by the Zimbardo Time Perspective Inventory (ZTPI) (Zimbardo and Boyd in J Personal Soc Psychol 77:1271–1288, 1999) and to measure happiness, the Subjective Happiness Scale of Lyubomirsky and Lepper (Soc Indic Res 46:137–155, 1999) was used. Regression analysis shows that time perspective is indeed associated with happiness and that, although the assumed shifts in time perspective over time were not found, age does act as a moderator of this association. With ageing, the negative association between a past-negative time perspective and happiness weakens. These results add to our understanding of the theoretical concept of time perspective and shed new light on the value of a balanced time perspective for someone’s wellbeing. Theoretical and practical implications of these findings are discussed.  相似文献

Domestic work can be perceived to be ‘dirty work’ in several ways: it is associated with dirt handling, low occupational prestige, and domestic workers have a servile relationship to their clients/employers. This stigma may negatively affect domestic workers' sense of self, and thus coping strategies appear to be critical. In this article, we explore the coping strategies that moderate the relation between the stigma of dirty work and domestic workers' sense of self, based on the analyses of 43 interviews with domestic workers in Belgium. By using a social stress approach in which stigma is considered a stressor, our results reveal a range of maladaptive and adaptive coping strategies that contribute to a negative or a more positive sense of self. Four main categories of coping strategies are discussed: confronting or countering perceptions and behaviours, occupational ideologies, social weighting and defensive tactics. The first two categories are adaptive coping strategies; the last two can be adaptive or maladaptive. We also reveal that workers used adaptive and maladaptive coping strategies simultaneously, leading to mixed implications for their sense of self.  相似文献
