Personnel selection as a signaling game 总被引:1,自引:0,他引:1
Personnel selection involves exchanges of information between job market actors (applicants and organizations). These actors do not have an incentive to exchange accurate information about their ability and commitment to the employment relationship unless it is to their advantage. This state of affairs explains numerous phenomena in personnel selection (e.g., faking). Signaling theory describes a mechanism by which parties with partly conflicting interests (and thus an incentive for deception) can nevertheless exchange accurate information. We apply signaling theory to personnel selection, distinguishing between adaptive relationships between applicants and organizations, among applicants, and among organizations. In each case, repeated adaptations and counteradaptations between actors can lead to situations of equilibrium or escalation (arms races). We show that viewing personnel selection as a network of adaptive relationships among job market actors enables an understanding of both classic and underexplored micro- and macro-level selection phenomena and their dynamic interactions. 相似文献

Either despite or because of their non-traditional approach, megachurches have grown significantly in the United States since
1980. This paper models religious participation as an imperfect public good which, absent intervention, yields suboptimal
participation by members from the church’s perspective. Megachurches address this problem in part by employing secular-based
group activities to subsidize religious participation that then translates into an increase in the attendees’ religious investment.
This strategy not only allows megachurches to attract and retain new members when many traditional churches are losing members
but also results in higher levels of an individual’s religious capital. As a result, the megachurch may raise expectations
of members’ levels of commitment and faith practices. Data from the FACT2000 survey provide evidence that megachurches employ
groups more extensively than other churches, and this approach is consistent with a strategy to use groups to help subsidize
individuals’ religious investment. Religious capital rises among members of megachurches relative to members of non-megachurches
as a result of this strategy. 相似文献

In team-handball, skilled athletes are able to adapt to different game situations that may lead to differences in movement variability. Whether movement variability affects the performance of a team-handball throw and is affected by different skill levels or throwing techniques has not yet been demonstrated. Consequently, the aims of the study were to determine differences in performance and movement variability for several throwing techniques in different phases of the throwing movement, and of different skill levels. Twenty-four team-handball players of different skill levels (n=8) performed 30 throws using various throwing techniques. Upper body kinematics was measured via an 8 camera Vicon motion capture system and movement variability was calculated. Results indicated an increase in movement variability in the distal joint movements during the acceleration phase. In addition, there was a decrease in movement variability in highly skilled and skilled players in the standing throw with run-up, which indicated an increase in the ball release speed, which was highest when using this throwing technique. We assert that team-handball players had the ability to compensate an increase in movement variability in the acceleration phase to throw accurately, and skilled players were able to control the movement, although movement variability decreased in the standing throw with run-up. 相似文献

Background
Increased sensitivity to proactive (PI) and retroactive (RI) interference has been observed in amnestic mild cognitive impairment (aMCI). PI and RI are often explained as being the result of a response competition mechanism. However, patients with aMCI are supposed to suffer mostly from encoding deficits. We hypothesized that in aMCI interference may occur at encoding and not only at the retrieval stage.Material and methods
We developed an original paradigm enabling PI and RI to be tested with and without response competitors. Eighteen young controls (YC), 16 elderly controls (EC) and 15 aMCI participated in the study.Results
The YC and EC groups presented interference effects only in conditions that included a direct response competitor. In contrast, aMCI had interference effects in all conditions including the one without response competitor.Conclusion
Increased sensitivity to interference in aMCI appears to occur at the encoding/consolidation stage and not only at the retrieval stage, as is the case in healthy subjects. This result is discussed in the context of the associative encoding deficits characterizing aMCI. 相似文献825.

Psychosocial stress precipitates a wide spectrum of diseases with major public-health significance. The fight-or-flight response is generally regarded as the prototypic human stress response, both physiologically and behaviorally. Given that having positive social interactions before being exposed to acute stress plays a preeminent role in helping individuals control their stress response, engaging in prosocial behavior in response to stress (tend-and-befriend) might also be a protective pattern. Little is known, however, about the immediate social responses following stress in humans. Here we show that participants who experienced acute social stress, induced by a standardized laboratory stressor, engaged in substantially more prosocial behavior (trust, trustworthiness, and sharing) compared with participants in a control condition, who did not experience socioevaluative threat. These effects were highly specific: Stress did not affect the readiness to exhibit antisocial behavior or to bear nonsocial risks. These results show that stress triggers social approach behavior, which operates as a potent stress-buffering strategy in humans, thereby providing evidence for the tend-and-befriend hypothesis. 相似文献

This paper examined the moderating role of positive and negative affect in the relationship between distributive justice expectations and applicants' intentions to recommend the organization or to litigate. Specifically, it was suggested and supported in two samples of, respectively, 1,409 and 486 applicants, that the positive relationship between distributive justice expectations and recommendation intentions was stronger for applicants high in positive affect. In the second sample, it was further found that the negative relationship between distributive justice expectations and litigation intentions was stronger among applicants high in negative affect. This research is the first to identify the distinct roles of positive and negative affect in shaping responses to expectations of (un)fairness in the personnel selection literature. Theoretical and practical implications are discussed. 相似文献

Abstract The present study examined the relations between temperamental traits distinguished in regulative theory of temperament, state anxiety, and metacognition as postulated in self-regulatory executive function (S-REF) theory of emotional disorder. Data analysis (n=315) consisted of independent and mediated effect analyses. Of the six traits, briskness, emotional reactivity and perseveration correlated significantly with both state anxiety and metacognitions (emotional reactivity and perseveration correlated positively, and briskness - negatively). These traits were predictors of state anxiety. Metacognition predicted state anxiety and relationships were independent of temperament. A mediating effect of metacognition was confirmed for the general index as well as negative and positive belief subscales. The findings support the metacognitive model of psychopathology and suggest that temperament is associated with metacognitions implicated in psychopathology and may have both direct and metacognitively mediated effects on anxiety. 相似文献

When driving a vehicle, either the driver or a passenger (henceforth: backseat driver) may be responsible for navigation. Research on active navigation, primarily addressed in virtual environments, suggests that controlling navigation is more central for spatial learning than controlling movement. To test this assumption in a real-world scenario, we manipulated movement control through seating participants in the front or the back position of a tandem bike, and navigation control by presenting differently detailed maps to participants unfamiliar (Experiment 1) or familiar (Experiment 2) with an environment. Landmark knowledge was tested with recognition tasks. For participants unfamiliar with the environment (Experiment 1), passive navigation enabled better landmark recognition than active navigation, but there was no effect of movement control. For participants more familiar with the environment (Experiment 2), there was no effect of navigation control, but drivers showed better landmark recognition than backseat drivers. These findings are discussed in relation to action memory research. Measures of route and survey knowledge demonstrated that good performance resulted from active navigation (Experiment 1-2). Moreover, with regard to these measures, driving compensated for passive navigation if the environment was familiar (Experiment 2). An additional experiment in a lab setting (Experiment 3) validated the manipulation of navigation control and the used tasks and demonstrated the importance of real environment exposure. As our findings suggest, driving may be more relevant for remembering landmarks, but actively controlling navigation (even as a backseat driver) is more relevant for remembering a route than maneuvering a vehicle. 相似文献

Numerical cognition is based on two components - number processing and calculation. Its development is influenced by biological, cognitive, educational, and cultural factors. The objectives of the present study were to: i) assess number processing and calculation in Brazilian children aged 7-12 years from public schools using the Zareki-R (Battery of neuropsychological tests for number processing and calculation in children, Revised; von Aster & Dellatolas, 2006) in order to obtain normative data for Portuguese speakers; ii) identify how environment, age, and gender influences the development of these mathematical skills; iii) investigate the construct validity of the Zareki-R by the contrast with the Arithmetic subtest of WISC-III. The sample included 172 children, both genders, divided in two groups: urban (N = 119) and rural (N = 53) assessed by the Zareki-R. Rural children presented lower scores in one aspect of number processing; children aged 7-8 years demonstrated an inferior global score than older; boys presented a superior performance in both number processing and calculation. Construct validity of Zareki-R was demonstrated by high to moderate correlations with Arithmetic subtest of WISC-III. The Zareki-R therefore is a suitable instrument to assess the development of mathematical skills, which is influenced by factors such as environment, age, and gender. 相似文献

ObjectivesAlthough the effect of exercise on cognitive functioning has received considerable empirical and theoretical attention, the influence of concurrent exercise on complex cognitive function remains poorly understood. Our research was designed to investigate working memory during a bout of dynamic exercise.DesignAn experimental design was used.MethodsIn two experiments, we examined the impact of moderate intensity exercise on performance of a paced auditory serial addition task (Experiment 1, N = 24) and a Sternberg task (Experiment 2, N = 120). The tasks were performed at rest and while cycling at different power outputs.ResultsWe found that moderate intensity exercise increased the number of correct responses at medium-to-fast stimulus presentation rates during the paced auditory serial addition task and lowered the response latency slopes during the Sternberg task.ConclusionsOur findings show that working memory is improved by dynamic exercise at moderate intensities and short duration. 相似文献
