Professional rejection is a widespread phenomenon—most, if not all, of us have or will experience it in our lifetimes. However, some are more adept at handling it than others. This paper examines individual differences in how people interpret and handle professional rejection, proposing a construct called professional rejection sensitivity. We focused on whether this construct predicts decreased self-promoting behaviors and increased self-silencing behaviors and, subsequently, whether that impacts career success for junior faculty. Moreover, we investigated whether women may be disproportionally predisposed to professional rejection sensitivity because they tend to experience more discrimination in the workplace than men. We collected self-report data (i.e., individual differences) and biodata (i.e., curriculum vitae) from 300 junior faculty and found evidence of gender differences, such that women perceive more discrimination and report higher professional rejection sensitivity than men. We also found that individuals who are higher in professional rejection sensitivity are more likely to practice self-silencing behaviors, and individuals who perceive more discrimination have lower career success. This paper serves as the first step in demonstrating the existence of professional rejection sensitivity, which can guide future research that addresses how individuals can overcome this disposition. To support this path of research, we conclude with suggestions for potential interventions. 相似文献

The purpose of the current study was to evaluate the effects of equivalence-based instruction (EBI) on learning to play individual notes and simple songs on the piano. Participants were 4 typically developing children and 4 children with a diagnosis of autism spectrum disorder (ASD). They were exposed to a series of auditory–visual matching-to-sample procedures using musical stimuli. Following training, participants were tested on the emergence of novel untrained relations and generalization in the form of playing two songs on a keyboard. Results suggest that the EBI was effective in teaching piano playing skills with both typically developing children and children with ASD. The success of this procedure is indicative of the wide-ranging applications of EBI to novel and creative domains. 相似文献

Variants of adaptive Bayesian procedures for estimating the 5% point on a psychometric function were studied by simulation. Bias and standard error were the criteria to evaluate performance. The results indicated a superiority of (a) uniform priors, (b) model likelihood functions that are odd symmetric about threshold and that have parameter values larger than their counterparts in the psychometric function, (c) stimulus placement at the prior mean, and (d) estimates defined as the posterior mean. Unbiasedness arises in only 10 trials, and 20 trials ensure constant standard errors. The standard error of the estimates equals 0.617 times the inverse of the square root of the number of trials. Other variants yielded bias and larger standard errors. 相似文献

This study investigated whether some categories of adverse life events are differentially associated with specific types of emotional disorders. A life self-report measure of major life events was completed by 42 subjects with diagnoses of anxiety disorders, 46 subjects with major depression, 26 subjects with hypochondriasis and 73 nonclinical subjects (controls). As predicted, the onset of anxiety disorders, depression, and hypochondriasis appears to be differentially related with life stress of ‘threat’, ‘loss’, and ‘health’, respectively, previously experienced by the clinical subjects. Also, there were significant differences between clinical and nonclinical subjects on both perceived life stress and number of life events reported. Findings suggest a differential implication of psychosocial stress categories in particular emotional disorders (i.e., anxiety, depressive and hypochondriacal disorders). These results expand previous findings that have demonstrated an association between negative life events and psychopathology. 相似文献

Abstract The main objective of this study is to test the effects over time of three role stress variables (role conflict, role ambiguity and role overload) on the three burnout dimensions (emotional exhaustion, depersonalization and personal accomplishment). Based on theoretical models on burnout and on meta-analytical research, it is hypothesized that the three role stress variables will predict changes over time in emotional exhaustion and depersonalization, but not in personal accomplishment. The results obtained by means of hierarchical regression analysis partially support the hypothesis. The three role stress variables predict emotional exhaustion over time. Role conflict and role overload predict depersonalization over time. Finally, contrary to expectations, role ambiguity predicts personal accomplishment over time. 相似文献

We measured depressive symptomatology of 134 outpatient veterans treated within a Behavioral Medicine Clinic utilizing three reliable instruments with depression subscales: Minnesota Multiphasic Personality Inventory (MMPI), Derogatis Stress Profile (DSP), and Symptom Checklist 90—Revised (SCL-90-R). Results indicate that although the instruments correlate significantly, they differ in sensitivity to depression and are clinically discordant. The MMPI classified a substantially higher number of patients as depressed than either the DSP or SCL-90-R. The present study argues that the discrepancy in clinical concordance and sensitivity of the three depression scales has considerable implications for psychologists concerned with the assessment and treatment of depression. 相似文献

A key problem in robotics is the construction of a map from its environment. This map could be used in different tasks, like localization, recognition, obstacle avoidance, etc. Besides, the simultaneous location and mapping (SLAM) problem has had a lot of interest in the robotics community. This paper presents a new method for visual mapping, using topological instead of metric information. For that purpose, we propose prior image segmentation into regions in order to group the extracted invariant features in a graph so that each graph defines a single region of the image. Although others methods have been proposed for visual SLAM, our method is complete, in the sense that it makes all the process: it presents a new method for image matching; it defines a way to build the topological map; and it also defines a matching criterion for loop-closing. The matching process will take into account visual features and their structure using the graph transformation matching (GTM) algorithm, which allows us to process the matching and to remove out the outliers. Then, using this image comparison method, we propose an algorithm for constructing topological maps. During the experimentation phase, we will test the robustness of the method and its ability constructing topological maps. We have also introduced new hysteresis behavior in order to solve some problems found building the graph. 相似文献

The purpose of this study was to investigate changes in postural sway and strategy elicited by lumbar extensor muscle fatigue. Specifically, changes in center of mass (COM), center of pressure (COP), and joint kinematics during quiet standing were determined, as well as selected cross correlations between these variables that are indicative of movement strategy. Twelve healthy male participants stood quietly both before and after exercises that fatigued the lumbar extensors. Whole-body movement and ground reaction force data were recorded and used to calculate mean body posture and variability of COM, COP, and joint kinematics during quiet standing. Three main findings emerged. First, participants adopted a slight forward lean post-fatigue as evidenced by an anterior shift of the COM and COP. Second, post-fatigue increases in joint angle variability were observed at multiple joints including joints distal to the fatigued musculature. Despite these increases, anterior-posterior (AP) ankle angle correlated well with AP COM position, suggesting the body still behaved similar to an inverted pendulum. Third, global measures of sway based on COM and COP were not necessarily indicative of changes in individual joint kinematics. Thus, in trying to advance our understanding of how localized fatigue affects movement patterns and the postural control system, it appears that joint kinematics and/or multivariate measures of postural sway are necessary. 相似文献

The present research focuses on the design and testing of a training program in learning strategies for Mathematics in Higher Education students. This research displays a quasiexperimental-sequential design with a non-equivalent control group. The research aims at revealing the effect of this training program both on the student's competence in learning strategies and on academic performance in this curricular area. There have been 176 students taking part in this research (74 students forming the experimental group and 72 forming the control group). The obtained results permit to assess the program efficiency as regards both trained strategies handling and specific performance improvement. 相似文献
