How can we explain that an assertion on something perceived can be understood in the same manner by somebody who cannot perceive that scene? This problem bases the interest in computational linguistics in how listener modeling could possibly be harmonized with reference semantics. Mental images substituting real perception appear as a way out. The architecture of the listener model has to be adapted to the creation and use of such pictorial data structures. Furthermore, the relation between the latter and a verbal (i. e., propositional) representation must be understood. The resulting architecture of a listener model with reference semantics can be employed to solve communicational problems from three general classes in a better way, as is demonstrated by an example implementation.  相似文献

Qualitative reviews of the withdrawal literature have reached inconsistent conclusions regarding the strength of the relationship between promotion and turnover. Several issues were addressed in this study which may account for these inconsistencies. First, we differentiate among three distinct operationalizations of promotion: (1) promotion satisfaction; (2) perceptions of promotional opportunity; and (3) actual promotion. We then conduct quantitative reviews using meta-analytic procedures on turnover and the three operationalizations of promotion. We found no significant relationships between promotion satisfaction and turnoveror between perceived promotional opportunities and turnover. However, a significant negative relationship was found between actual promotion and turnover. Theoretical implication of these findings are presented.  相似文献

The relationship between academic gender bias and female students' agentic self-efficacy expectations was examined. Agentic self-efficacy expectations was defined as an individual's beliefs about her ability to successfully engage in proactive educational and career facilitative behaviors. Participants included 67 full-time junior and senior undergraduate women enrolled in traditional, nontraditional, and gender-neutral majors. Results revealed that perceived academic gender bias was significantly predictive of agentic self-efficacy expectations, above and beyond the contributions of sex role attitudes, gender concentration of major, and race/ethnicity. Implications for women's career development and future research are discussed.  相似文献

Situational performance constraints, task interest, and pay contingencies were manipulated in a laboratory study in order to investigate the cognitive mechanisms associated with the previously observed detrimental effects of constraints on affective task reactions. It was hypothesized that feelings of task competence and self-determination would account for both the direct and the interactive effects of constraints on motivation and satisfaction. The results of the study indicated that despite the fact that participants' performance was being constrained and they were aware of these constraints, the mere presence of the constraints alone failed to result in lower levels of satisfaction or motivation on a proofreading task. Post hoc analyses suggested that the constraints, in fact, led to negative affective task reactions when they also reduced participants' feelings of competence and self-determination. Interestingly, participants' generalized locus of control was associated with such effects. Internals tended to maintain stronger feelings of competence and self-determination than externals in the presence of constraints, thereby also maintaining greater motivation and satisfaction.  相似文献

This study reviews research on cultural differences in “probabilistic thinking” and presents some intra- and inter-cultural findings. Strong differences are shown to exist between people raised under Asian and British cultures on measures of this ability. These differences were found to out-weigh any influence of subculture, religion, occupation, arts/science orientation and sex. Generally, Asians were found to adopt a less finely differentiated view of uncertainty both numerically and verbally than did the British sample. Numerical probabilities assessed by the Asians were more extreme and less realistic than those assessed by the British sample. Possible antecedents of these differences are outlined, and cultural differences in probabilistic thinking are shown to be compatible with decriptions of cultural differences in business decision making. It is argued that there are qualitative cultural differences in ways of dealing with uncertainty.  相似文献

In Experiment I subjects imaged an alphanumeric character either upright or upside-down, and triggered a test display character. Their task was to decide as quickly as possible whether the test character was NORMAL or MIRRORED. On 72% of the trials the test was at the orientation imaged. Reaction time (RT) was then about 200 ms longer in the upside-down image condition. This difference reduced with practice. On the remaining trials the orientation of the test character differed from that of the prepared image. For upright images RT increased monotonically with the angular difference in orientation between test and image. For upside-down images RT did not increase monotonically with angular difference as there was a wide dip around the upright. Further experiments suggested that upside-down images can be rotated, but at considerably slower rates than upright ones, and that the apparent rates of rotation for upside-down images are dependent upon the width of the sector tested. These results indicate that visual short-term memory (STM) and long-term memory (LTM) are distinct; that the process of mental rotation does not operate directly upon LTM; and that functionally, upright and rotated images may differ in important ways.  相似文献

Considers a preventive intervention effort designed to modify the characteristics and regularities of the school environment so as to enhance the expectations conveyed to high risk students. Employing this case effort (Weinstein et al., 1991) as a base, several issues are highlighted that deserve greater attention in the design, implementation, assessment, and reporting of other preventively-focused social interventions. These issues include: (1) the degree of program implementation fidelity, (2) the impact a lack of attainment of program fidelity may have on arriving at erroneous evaluation conclusions about social programs, (3) the ways in which the theory and basic research employed in the program rationale is appropriate to and reflected in the program as designed, (4) issues of program potency and dosage, (5) the ways in which quantitative and qualitative evaluation data can enhance each other, and (6) the import of evaluability assessments of programs prior to moving to outcome evaluations. In addressing these issues, the importance of developmentally- and ecologically-informed program formulations is underscored. Finally, the critical role that program reports such as the Weinstein paper, with its careful discussion of both the process of implementation and outcome assessments, can play in the development of more effective prevention program implementation efforts is highlighted.  相似文献

Thirty-two third- and fourth-grade popular and aggressive boys were observed individually attempting to enter a game being played by a mixed-status unfamiliar-peer dyad in both competitive and cooperative game settings. Consistent with previous findings, popular entry children were accepted more readily into the game situation than were aggressive children. Popular children tended to approach the situations using more prosocial questions while their aggressive peers tended to use demands. More differences in entry strategies were noted in the competitive than in the cooperative game setting. While most entry children directed their first entry bid toward the aggressive game host, they reported having liked the popular game host best when the game was finished. Additionally, the quality of game interactions was observed to become more positive following a popular child's entry, while becoming more negative following an aggressive child's entry. The results are discussed in terms of leadership roles and implications for both assessment and intervention settings and strategies.The authors wish to acknowledge the support and cooperation of the Greensboro, North Carolina, public and parochial schools, and the assistance of William Livingston.This paper was presented at the 19th Annual Convention of the Association for the Advancement of Behavior Therapy, Houston, Texas.  相似文献
