Innovation is considered essential for today's organizations to survive and thrive. Researchers have also stressed the importance of leadership as a driver of followers' innovative work behavior (FIB). Yet, despite a large amount of research, three areas remain understudied: (a) The relative importance of different forms of leadership for FIB; (b) the mechanisms through which leadership impacts FIB; and (c) the degree to which relationships between leadership and FIB are generalizable across cultures. To address these lacunae, we propose an integrated model connecting four types of positive leadership behaviors, two types of identification (as mediating variables), and FIB. We tested our model in a global data set comprising responses of N = 7,225 participants from 23 countries, grouped into nine cultural clusters. Our results indicate that perceived LMX quality was the strongest relative predictor of FIB. Furthermore, the relationships between both perceived LMX quality and identity leadership with FIB were mediated by social identification. The indirect effect of LMX on FIB via social identification was stable across clusters, whereas the indirect effects of the other forms of leadership on FIB via social identification were stronger in countries high versus low on collectivism. Power distance did not influence the relations.  相似文献

This study examined perceived environment among families with a depressed, depressed and anxious, anxious, or normal child from the 4th to 7th grades. Fifty-one such children were classified according to criteria from the K- SADS and a set of self-ratings of depression and anxiety. Results showed that children in all three diagnostic groups, and to a lesser extent their mothers, experienced their families as more distressed on a host of dimensions relative to controls. In addition, significant differences were found between families with a depressed and anxious child and those with an anxious child. Discriminant function analyses revealed that 68.63 % of the youngsters could be classified correctly into depressed and anxious groups on the basis of their family ratings alone.  相似文献

Eighteen language-impaired children and 25 non-language-impaired children were evaluated to investigate the relationship between language ability and selected aspects of the five-component problem-solving process defined by Kagan and Kogan (1970). Non-impaired children performed better than language-impaired children on nearly all components of the problem-solving process. Language-impaired children had particular difficulties in the areas of coding and hypothesis generation. In fact, coding ability was inversely related to the number of errors made in hypothesis evaluation. Coding ability was also positively correlated with language ability. The exact causal relationship between coding ability, language ability, and error-making in hypothesis evaluation is unclear; however, improving coding skills through training may increase automaticity and lead to improved performance in the higher levels of the problem-solving process.  相似文献

Animal data suggest that shock sensitization as well as aversive learning potentiates the acoustic startle reflex. The present experiment tested, whether this shock sensitization also occurs in human subjects and whether it precedes aversive conditioning. Sixty subjects viewed—prior to conditioning—a series of slides of different emotional contents including the to be conditioned stimuli (CSs). Afterwards, the experimenter attached the shock electrodes and initiated shock exposure. Then, subjects were randomly assigned to view a series of two slides, each for eight acquisition trials in which one slide was followed by a shock. Subsequently, extinction trials (12 for each slide) were administered. During preconditioning, acquisition, and extinction, startle probes occurred unpredictably during and between slide viewing. Preconditioning data replicated previous results by Lang and his associates, showing that the startle response magnitude is directly related to the affective valence induced by the slides. Shock exposure strongly facilitated the startle reflex magnitude. This shock sensitization was absent for the skin conductance response. Course of learning also varied for both response systems. The data suggest that startle reflex potentiation indexes the acquisition of an avoidance disposition, which is preceded by a general sensitization of the protective reflexes. Skin conductance learning follows arousal changes and is modulated by cognitive processes.  相似文献

Discriminant function analysis was used to determine whether performance on temporal perception and production tasks alone could correctly classify children as language-impaired or normal. The analysis identified six variables, all of which assessed temporal perceptual and production abilities, which taken in combination correctly classified 98% of participating subjects. None of these variables assess the higher-level linguistic abilities (semantic, syntactic, pragmatic) that have classically been considered to be deficient in language-impaired children, or have been used to diagnose them clinically.  相似文献

We examined the conjecture that relations between constructs across cultures may be susceptible to cultural moderation where the performance of the criterion construct is discretionary. This hypothesis was investigated using the relationship between personality and three performance constructs, with samples from the United States and New Zealand, two ideologically distinct cultures with respect to achievement orientation. All hypotheses were supported by results of hierarchical moderated regression analyses using bias free measures, suggesting that considering whether construct behaviors are discretionary is important when considering the merit of generalizing research findings across cultures.  相似文献

A single case study recently documented one woman's ability to recall accurately vast amounts of autobiographical information, spanning most of her lifetime, without the use of practiced mnemonics (Parker, Cahill, & McGaugh, 2006). The current study reports findings based on eleven participants expressing this same memory ability, now referred to as Highly Superior Autobiographical Memory (HSAM). Participants were identified and subsequently characterized based on screening for memory of public events. They were then tested for personal autobiographical memories as well as for memory assessed by laboratory memory tests. Additionally, whole-brain structural MRI scans were obtained. Results indicated that HSAM participants performed significantly better at recalling public as well as personal autobiographical events as well as the days and dates on which these events occurred. However, their performance was comparable to age- and sex-matched controls on most standard laboratory memory tests. Neuroanatomical results identified nine structures as being morphologically different from those of control participants. The study of HSAM may provide new insights into the neurobiology of autobiographical memory.  相似文献
