Subjective career success has long been of interest to scholars because of its importance in the career area. However, the subjective career success literature suffers from the lack of measurement. To fill this void, after reviewing the limitations of the existing instruments, the current study developed a three‐dimensional scale of subjective career success based on the framework of Zhou et al. Three independent studies were conducted using three separate samples (N = 244; N = 411; N = 254) in China to examine the reliability and validity of the developmental scale. The results provided evidence of internal homogeneity, structural validity, convergent validity, discriminant validity, and incremental validity of the developed scale. To conclude the study, the limitations of the article and implications for future study were discussed.  相似文献

Three experiments using computer-generated human figures showed that after a prolonged observation of eyes looking to the left (or right), eyes looking directly toward the viewer appeared directed to the right (or left). Observation of an arrow pointing left or right did not induce this aftereffect on the perceived eye direction. Happy faces produced the aftereffect more effectively than surprised faces, even though the image features of the eyes were identical for both the happy and the surprised faces. These results suggest that the eye direction aftereffect may reflect the adaptation of relatively higher-level mechanisms analyzing the others eye direction.  相似文献

Using the Hebb Digits task, an incidental sequential learning paradigm, the effects of chunking of both the presentation and response phases of performance were examined. In the first experiment, consistent stimulus chunking increased learning, and performance was at an equivalent level to this when consistent chunking of both stimuli and responses was present. Consistent chunking of the responses alone did not significantly improve learning over a baseline condition where neither stimuli nor responses were chunked. The disruption of response organization in a second experiment, through a random response condition, failed to impact learning in non-chunked and stimulus chunked conditions. A third experiment found that response chunking did benefit learning in a condition where stimuli were presented in random chunks. A final experiment suggested extended processing of the digits could not account for performance gains in the stimulus chunking condition. Overall, the results suggest that the enhanced effects of chunking on learning were stimulus-driven rather than response-driven, except under conditions that constrained a consistent pattern of stimulus organization.  相似文献

Our purpose in the following was to investigate the start-up rhetoric employed by U.S. President Barack Obama in his speeches. The initial 5 min from eight of his speeches from May to September of 2009 were selected for their variety of setting, audience, theme, and purpose. It was generally hypothesized that Barack Obama, widely recognized for the excellence of his rhetorical performance, would pursue both constant and variable strategies in his effort to establish contact with his audience. More specifically, it was hypothesized that the make-up of the audience—primarily native or non-native speakers of English—would be a prominent independent variable. A number of temporal and verbal measures were used as dependent variables. Variations were evident in mean length in syllables and duration in seconds of utterances (articulatory phrases), articulation rate in syllables per second of ontime, mean duration of silent pauses in seconds, and frequency of fillers, hesitations, colloquial words and phrases, introductory phrases, and 1st person singular pronominals. Results indicated that formality versus informality of the setting and presence or absence of a teleprompter were more prominent than native versus non-native audiences. Our analyses confirm Obama’s skillfulness in challenging and variable settings and clearly detect orderliness and scientific generalizability in language use. The concept of orality/literacy provides a theoretical background and emphasizes dialogical interaction of audience and speaker.  相似文献

An alternative models framework was used to test three confirmatory factor analytic models for the Short Leyton Obsessional Inventory-Children’s Version (Short LOI-CV) in a general population sample of 517 young adolescent twins (11–16 years). A one-factor model as implicit in current classification systems of Obsessive–Compulsive Disorder (OCD), a two-factor obsessions and compulsions model, and a multidimensional model corresponding to the three proposed subscales of the Short LOI-CV (labelled Obsessions/Incompleteness, Numbers/Luck and Cleanliness) were considered. The three-factor model was the only model to provide an adequate explanation of the data. Twin analyses suggested significant quantitative sex differences in heritability for both the Obsessions/Incompleteness and Numbers/Luck dimensions with these being significantly heritable in males only (heritability of 60% and 65% respectively). The correlation between the additive genetic effects for these two dimensions in males was 0.95 suggesting they largely share the same genetic risk factors.  相似文献

The compressive deformation and fracture features of Zr59Cu20Al10Ni8Ti3 bulk metallic glassy samples with aspect ratios in the range of 0.67–2.00 have been investigated. The compressive plastic strain of the glass monotonically increases with decreasing aspect ratio, but the maximum strength almost maintains a constant value of 1.77–1.88?GPa. All the compressive shear-band angles are equal to?~40° if modified by the rotation of the primary shear bands.  相似文献

We assessed the role of parental behaviors on sport performance anxiety. Measures of trait anxiety, parental pressure, and parent-initiated motivational climate were administered to youth swimmers throughout the season. High parental pressure within either a low mastery or a high ego motivational climate was associated with the highest levels of anxiety at all time points. An early-season, high-pressure/low-mastery combination was also associated with relative increases in anxiety over the season, whereas high pressure within a high mastery climate was associated with relative decreases. Results indicate that parental pressure can have differential effects depending upon motivational climate.  相似文献
