Prior research on the benefits of modest self-presentation in organizational contexts has shown positive effects on several career-related outcomes, including employees' reputation, organizational support, and mentoring. However, little is known about the nature, mechanisms, and boundary conditions of this promising impression management tactic. Our study addresses this research gap by integrating two theoretical conceptions of modesty, i.e., impression management modesty (IM modesty) and trait modesty. We developed and tested an overarching theoretical model that postulates positive interactive effects of employees' IM modesty and trait modesty on supervisor ratings of employees' likeability, competence, and job performance. Data on 233 employee–supervisor dyads were analyzed using hierarchical regression and conditional process analyses. As expected, the effects of IM modesty were systematically moderated by employees' trait modesty: For employees with high trait modesty, IM modesty demonstrated significant positive effects on supervisor ratings of employee likeability and competence, which in turn were associated with higher job performance ratings. For employees with low trait modesty, however, using IM modesty was neither beneficial nor detrimental to supervisor evaluations. Implications for theory, practice, and avenues for future research are discussed.  相似文献

The psyche of a human being is formed in strict correlation with the development of the brain. Genetic, epigenetic regulatory and prenatal influences through the brain of the mother as well as postnatal influences, predominantly as early childhood attachment experiences are all intertwined with each other. This takes place at three “limbic levels”: a lower level at which the infantile temperament resides, a middle level of early childhood impressioning experiences and an upper limbic level of socialization. The cognitive language level develops in a relatively independent manner. At the three limbic levels six psychoneural systems are operative, namely the stress processing, the self-calming, the impulse inhibiting, the motivation, the attachment and the reality and risk perception systems. Mental disorders are characterized throughout by disorders of the first two systems, predominantly in the form of greatly increased cortisol levels and greatly reduced serotinin levels. These then induce deficits in other systems; however, in less severe cases compensatory processes can occur via an attachment-related increased release of oxytocin. Similar processes also occur within the “therapeutic alliance” in the patient-therapist relationship.  相似文献

Successful psychotherapy requires structural and functional changes in limbic brain centers; however, these differ in manner, effectiveness and dynamics. One primary factor is the therapeutic alliance, i.?e. the mutual trust between patient and therapist. This factor reduces the level of stress hormones via release of the “bonding hormone” oxytocin and increases the production of serotonin and endogenous opioids. As a consequence, a rapid improvement of the mental emotional state of the patient often occurs; however, this is not accompanied by the deeper and longer lasting neuronal changes necessary to treat severe mental illnesses. This occurs only when dysfunctional habits of feeling, thinking and acting residing primarily in the basal ganglia (striatopallidum and nucleus accumbens) and amygdala are reorganized. Rather than being an explicit cognitive process this represents an implicit procedural process, which after an extensive search for resources requires a sufficient length of time and frequent rehearsal of more adaptive emotional attitudes and patterns of behavior. Apparently, this is promoted by the generation of new nerve cells from neural stem cells induced by oxytocin and neurotrophins, such as brain-derived neurotrophic factor (BDNF), taking place in the hippocampus and the basal ganglia. All these facts are in favor of a long-term psychotherapy at least in cases of severe mental diseases.  相似文献

The now available unabridged correspondence between Freud and Abraham leads to a re‐evaluation of the significance of Abraham's work. The author proposes the thesis that clinical observations by Karl Abraham of the ambivalence of object relations and the destructive‐sadistic aspects of orality have an important influence on the advancement of psychoanalytical theory. The phantasy problem of the Wolf Man and the question of the pathogenic relevance of early actual, or merely imagined traumata led Freud to doubt the validity of his theory. He attempted repeatedly to solve this problem using libido theory, but failed because of his problematic conception of oral erotics. The pathogenic effect of presymbolic traumatizations cannot be demonstrated scientifically because of the still underdeveloped brain in the early stage of the child's development. Consequently, the important empirical evidence of a scientific neurosis theory could not be provided. A revision of the theory of the instincts thus became necessary. With Abraham's clinical contributions and other pathologic evidence, Freud was, with some reservation, forced to modify his idea of oral erotics by ascribing to it a status of a merely constructed and fictive phase of oral organization. A solution was eventually facilitated via recognition of non‐erotic aggression and destruction, thereby opening libido theory to fundamental revisions. Driven by the desire to develop a scientific theory, Freud initially had, in his first theory of the instincts, assumed a strongly causal‐deterministic view on Psychic Function. His third revision of theory of the instincts, Beyond the Pleasure Principle including the death instinct hypothesis, considered the hermeneutic aspect of psychoanalytic theory, which had previously existed only implicitly in his theory. Further development of the death instinct hypothesis by Melanie Klein and her successors abandoned quantitative‐economic and causal‐deterministic principles, and instead focused on the practical utility of the psychoanalytic theory.  相似文献

Perfectionism is hypothesized to contribute to the etiology of anorexia nervosa (AN). However, there is little research regarding whether individuals with AN can be classified according to maladaptive (e.g., evaluative concerns) and adaptive (e.g., high personal standards) facets of perfectionism that predict distinct outcomes and might warrant different intervention approaches. In this study, a latent profile analysis was conducted using data from adults with AN (n?=?118). Frost Multidimensional Perfectionism Scale (Frost et al. Cognitive Therapy and Research, 14(5), 449–46, 1990) subscales were used to identify subgroups differing according to endorsed perfectionism features (e.g., adaptive and maladaptive perfectionism). Generalized linear models were used to compare subgroups on eating disorder and affective symptoms measured through questionnaire and ecological momentary assessment. Four subgroups were identified: (a) Low Perfectionism; (b) High Adaptive and Maladaptive Perfectionism; (c) Moderate Maladaptive Perfectionism; and (d) High Maladaptive Perfectionism. Subgroups differed on overall eating disorder symptoms (p?<?.001), purging (p?=?.005), restrictive eating (p?<?.001), and body checking (p?<?.001) frequency, depressive (p?<?.001) and anxiety (p?<?.001) symptoms, and negative (p?=?.001) and positive (p?<?.001) affect. The Low Perfectionism group displayed the most adaptive scores and the Moderate and High Maladaptive Perfectionism groups demonstrated the most elevated clinical symptoms. The High Adaptive and Maladaptive Perfectionism group demonstrated low affective disturbances, but elevated eating disorder symptoms. Results support the clinical significance of subtyping according to perfectionism dimensions in AN. Research is needed to determine if perfectionism subtyping can enhance individualized treatment targeting in AN.  相似文献

The evidence for associations between genetic polymorphisms and complex behavioral/psychological phenotypes (traits) has thus far been weak and inconsistent. Using the well-studied Val158Met polymorphism of the catechol-O-methyltransferase (COMT) gene as an example, we demonstrate that using theoretical models to guide phenotype definition and measuring the phenotypes of interest with a high degree of specificity reveals strong gene-behavior associations that are consistent with prior work and that would have otherwise gone unnoticed. Only after statistically controlling for irrelevant portions of phenotype variance did we observe strong (Cohen's d = 0.33-0.70) and significant associations between COMT Val158Met and both cognitive and affective traits in a healthy male sample (N = 201) in Study 1: Carriers of the Met allele scored higher in fluid intelligence (reasoning) but lower in both crystallized intelligence (general knowledge) and the agency facet of extraversion. In Study 2, we conceptually replicated the association of COMT Val158Met with the agency facet of extraversion after partialing irrelevant phenotype variance in a female sample (N = 565). Finally, through reanalysis of a large published data set we showed that Met allele carriers also scored higher in indicators of fluid intelligence after partialing verbal fluency. Because the Met allele codes for a less efficient variant of the enzyme COMT, resulting in higher levels of extrasynaptic prefrontal dopamine, these observations provide further support for a role for dopamine in both intelligence and extraversion. More importantly, the present findings have important implications for the definition of psychological phenotypes in neurogenetic research.  相似文献

The aim of this study was to investigate the spatial orienting of visual attention in depth under purely stereoscopic viewing conditions. Random-dot stereograms were used to present disparity-defined target stimuli that were either validly or invalidly cued in depth. In separate tasks, participants responded either to the relative depth of the target (protruding vs. receding) or to its shape (square vs. diamond). Stimulus onset asynchronies (SOAs) between an uninformative exogenous cue and target were varied from 250 to 600?ms. For both tasks, mean response times (RTs) were shorter for validly than invalidly cued target depths and this RT advantage was essentially restricted to the shortest SOA of 250?ms. These results indicate that attention can be reflexively allocated to locations in stereo depth under conditions of low perceptual load, and independent of whether depth is relevant to the task or not.  相似文献

Early predictors of high school mathematics achievement   总被引:1,自引:0,他引:1  
Identifying the types of mathematics content knowledge that are most predictive of students' long-term learning is essential for improving both theories of mathematical development and mathematics education. To identify these types of knowledge, we examined long-term predictors of high school students' knowledge of algebra and overall mathematics achievement. Analyses of large, nationally representative, longitudinal data sets from the United States and the United Kingdom revealed that elementary school students' knowledge of fractions and of division uniquely predicts those students' knowledge of algebra and overall mathematics achievement in high school, 5 or 6 years later, even after statistically controlling for other types of mathematical knowledge, general intellectual ability, working memory, and family income and education. Implications of these findings for understanding and improving mathematics learning are discussed.  相似文献

Abstract

Optimism was investigated in a sample of audiology clinic patients, consisting of one group of tinnitus sufferers (N = 30) and one group of hearing impaired subjects not experiencing tinnitus (N = 44). Optimism was measured by the Life Orientation Test (LOT). In the tinnitus group the LOT correlated significantly with measures of tinnitus related distress and in the hearing impaired group with measures of disability and emotional reactions due to the hearing impairment. Cronbach's alphas for the measures used were generally high. Principal components analysis of the LOT confirmed earlier findings by showing two separate factors; one with the positively worded LOT items reflecting the presence of optimism and one with the negatively worded LOT items reflecting the presence of pessimism. The results indicate that dispositional optimism is an usable concept in research with audiological samples, and that optimism is related with tinnitus distress and experienced disability and emotional reactions due to hearing impairment. Further research should investigate the possible role of personality factors in tinnitus and hearing impairment.  相似文献
