The present study examined the associations of implicit and explicit power motives with the well-being of teachers. Teachers (N = 170) participated in an online assessment, which included measures for implicit motives (assessed by the operant motive test), explicit motives, and well-being. We expected congruently high power motives to be linked with the highest levels of well-being. We tested this assumption using polynomial regressions with response surface analysis. Results were consistent with our hypothesis. Additionally, there was an effect of directional motive incongruence (a combination of a low implicit and a high explicit power motive was associated with higher well-being than a high implicit/low explicit combination), which did not hold when controlling for emotional stability. Results for achievement were comparable, but weaker, and there was no effect for motive incongruence. No significant associations were found for motive (in)congruence in the affiliation domain. Our findings underline the importance of the power motive in understanding individual differences in teachers’ well-being.  相似文献

Purpose

Adopting an information processing perspective, we argue that in pay-for-performance contexts, pay secrecy may adversely affect the ability of members of newly formed, virtual work groups to source assistance from those most able to provide it, referred to here as efficacious help-seeking.

Design/Methodology/Approach

We conducted a repeated-measures laboratory study in which one hundred forty-six participants interacted with three confederates, each with a varying level of skill. Participants’ help-seeking behaviors were recorded and efficacious help-seeking was examined as a function of the four pay transparency conditions.

Findings

Our findings reveal that accurate perception of task expertise of the highest paid work group member mediates the impact of pay transparency on members’ efficacious help-seeking. The findings also show that the positive relationship between pay transparency and efficacious help-seeking is amplified for average and high performers and that for these same individuals a shift from secrecy to transparency is accompanied by a significant increase in efficacious help-seeking.

Implications

This study extends pay secrecy research by shifting the focus away from fairness, instrumentality, and sorting and toward information processing. More specifically, the study highlights how pay and pay comparisons can influence inter-relating behaviors in organizations in general and expertise identification and help seeking behaviors in particular.

Originality/Value

We believe this is the first study to directly examine how the availability of pay comparison information determines inter-relating behaviors in organizations. The study offers insight for pay policy in organizations that rely upon employee help-seeking, showing that efficacious help-seeking can be enhanced through transparent pay practices. This is particularly evident in the virtual teams examined in the present study.

Humans are born with the ability to mentally represent the approximate numerosity of a set of objects, but little is known about the brain systems that sub‐serve this ability early in life and their relation to the brain systems underlying symbolic number and mathematics later in development. Here we investigate processing of numerical magnitudes before the acquisition of a symbolic numerical system or even spoken language, by measuring the brain response to numerosity changes in pre‐verbal infants using functional near‐infrared spectroscopy (fNIRS). To do this, we presented infants with two types of numerical stimulus blocks: number change blocks that presented dot arrays alternating in numerosity and no change blocks that presented dot arrays all with the same number. Images were carefully constructed to rule out the possibility that responses to number changes could be due to non‐numerical stimulus properties that tend to co‐vary with number. Interleaved with the two types of numerical blocks were audio‐visual animations designed to increase attention. We observed that number change blocks evoked an increase in oxygenated hemoglobin over a focal right parietal region that was greater than that observed during no change blocks and during audio‐visual attention blocks. The location of this effect was consistent with intra‐parietal activity seen in older children and adults for both symbolic and non‐symbolic numerical tasks. A distinct set of bilateral occipital and middle parietal channels responded more to the attention‐grabbing animations than to either of the types of numerical stimuli, further dissociating the specific right parietal response to number from a more general bilateral visual or attentional response. These results provide the strongest evidence to date that the right parietal cortex is specialized for numerical processing in infancy, as the response to number is dissociated from visual change processing and general attentional processing.  相似文献

Objective: Communication of cancer information is an important element of cancer control, but cancer fear may lead to information avoidance, especially when coping is low. We examined the association between cancer fear and cancer information avoidance, and tested whether this was exacerbated by psychosocial stress.

Design: Cross-sectional survey of 1258 population-based adults (58–70 years) in England.

Main outcome measures: Cancer fear (intensity and frequency), perceived psychosocial stress and cancer information avoidance. Control variables were age, gender, ethnicity, marital status and education.

Results: A quarter (24%) of respondents avoided cancer information. Ordinal logistic regression analyses showed main effects of psychosocial stress (OR = 1.17, 95% CI 1.07–1.29) and cancer fear: cancer information avoidance was lowest in those with no cancer fear (13%), followed by those with moderate (24%; OR = 2.15, 95% CI: 1.49–3.12), and high cancer fear (35%; OR = 3.90, 95% CI: 2.65–5.73). In the adjusted model, the interaction between cancer fear and stress was significant (OR = 1.14, 95% CI 1.004–1.29, p < .05): 40% of those with high fear/high stress avoided cancer information compared with 29% with high fear/low stress.

Conclusion: Cancer fear and psychosocial stress interact to produce disengagement with cancer-related information, highlighting the importance of affective processes to cancer control efforts.  相似文献

In most cross-national research on Life Satisfaction (LS) an implicit assumption appears to be that the correlates of LS are the same the world over; ‘one size fits all’. Using data from the World Values Survey (1999–2014), we question this assumption by assessing the effects of differing personal values/life priorities on LS in five world regions: the West, Latin America, the Asian-Confucian region, ex-Communist Eastern Europe, and the Communist countries of China and Vietnam. We indicate that differing values - traditional family values, friendship and leisure values, materialistic values, political values, prosocial and environmental values, and religious values – are endorsed to varying degrees in different parts of the world, and vary in whether they have positive or negative effects on LS. Personal values provide the basis for alternative ‘recipes’ affecting LS. By ‘recipes’ we mean linked set of values, attitudes, behavioural choices and domain satisfactions that have a positive or negative effect on LS. We estimate structural equation models which indicate that differing values-based recipes help to account for large, unexpected differences between mean levels of LS in the five world regions, compared with the levels ‘predicted’ by GDP per capita. In particular, the high priority given to traditional family and religious recipes in Latin America helps to account for unexpectedly high LS in that region. Deficits in prosocial attitudes and behaviours partly account for low LS in ex-Communist Eastern Europe.

There is evidence that subjective health is an important variable in general health outcomes. It can be an indicator of the individual's overall health status, creating a reliable and valid estimate about health. Quality of life (QoL) assessment can be associated with the individuals' subjective assessment of their own health status. The aim of the present study was to investigate variables associated with subjective perception of health in older inpatients. Ninety elderly inpatients over 60 years old were interviewed. The perception of health assessment (healthy/unhealthy) allocated elders in either of two groups. All the elders answered sociodemographic questions, the WHOQOL-100 and the Beck Depression Inventory (BDI). Comparing the group that considered themselves unhealthy to the other group, the former showed a tendency of worse QoL assessments in five out of six domains investigated. Significant differences were found for the physical and level of independence domains, as well as overall QoL. There was a significant association between health perception and lower intensity of depressive symptoms, as well as better QoL perception in the level of independence domain. This study shows the existence of an association between depressive symptoms and health assessment. It also suggests that the independence dimension is important in the elders' perception of their health status. These findings can help identify cause-effect relations between variables in aging studies involving health indicators and bring new intervention proposals for the elderly.  相似文献

We present a new experimental paradigm where choice-induced preference change is measured for alternatives which are never compared directly, but rather confronted with other alternatives in a way which keeps choices predictable without exogenously manipulating them. This implicit-choice design improves on the free-choice paradigm, avoiding the recently criticized selection bias. Rating and ranking spreads in two experiments show that preference-based choices feed back into and alter preferences even if choices are not directly among similarly evaluated alternatives. In agreement with recent brain-imaging evidence, response time measurements for direct choice pairs in our experiments indicate that reappraisal processes are already triggered during decision making, with larger post-choice spreads (sharper attitude change) being associated to quicker decisions.  相似文献

The effect of exposure to the contextual features of the /pt/ cluster was investigated in native-English and native-Polish listeners using behavioral and event-related potential (ERP) methodology. Both groups experience the /pt/ cluster in their languages, but only the Polish group experiences the cluster in the context of word onset examined in the current experiment. The /st/ cluster was used as an experimental control. ERPs were recorded while participants identified the number of syllables in the second word of nonsense word pairs. The results found that only Polish listeners accurately perceived the /pt/ cluster and perception was reflected within a late positive component of the ERP waveform. Furthermore, evidence of discrimination of /pt/ and /p?t/ onsets in the neural signal was found even for non-native listeners who could not perceive the difference. These findings suggest that exposure to phoneme sequences in highly specific contexts may be necessary for accurate perception.  相似文献
