In two experiments with geometrical figures as stimuli, constructed in order to generate perceptual variation of roundness and height, four multidimensional scaling methods were compared, two metric and two nonmetric. The methods gave similar solutions. The fact that the solutions could be interpreted in accordance with expectations, points to the validity of the methods. 相似文献

This paper reports a new approach to estimating the extent to which words have predominant noun and verb usages which do not require human judgments about parts of speech. The Hyperspace Analog to Language model (HAL, Lund & Burgess, 1996) was used to computationally estimate noun vs verb usage based on the statistical regularities present in a large-scale electronic text corpus. This measure can be used to estimate the extent to which a given word occurs in typical noun or verb sentence contexts (i.e., its distributional typicality) in informal contemporary discourse. 相似文献

Examined persistence in the daily use of fluoride mouthrinse among adolescents as a function of an induced-choice manipulation concerning self-management strategies and freedom to participate in the program. Seventh-grade boys and girls from urban and suburban schools were randomly assigned to a series of either high- or low-choice decisional control manipulations; their daily, home use of fluoride was monitored over a 20-week period. In order to ameliorate the relatively lower persistence rates found previously among suburban (vs. urban) students, all students were given self-management and action instructions as per previous studies. Although suburban students still declined in persistence relative to urban students, female students who received high choice persisted at a higher rate than girls who received low choice. Boys, for the most part, were unaffected by the manipulation. In addition, students' self-reported work orientation was also positively associated with persistence. 相似文献

It is argued that (1) the halo-model of Micko is probably too restrictive to fit empirical data, (2) the model misrepresents unrelated percepts as bipolar structures, (3) all variations will probably be interpreted as qualitative, (4) the model requires all dimensions to be bipolar, (5) interpretations of orthogonality of factors and of factor loadings become problematic, (6) the halo may be regarded as a sort of “surface variation,” (7) the common part of two percepts is inadequately defined, and (8) the opposite part of two percepts is neglected. 相似文献

Customers who purchased a household cleaning product from a door-to-door salesman were offered a monetary rebate after the sale. Customers accepted the rebate when it came from a company, but not when it came from the salesman. A second study replicated these findings and also showed that customers were reluctant to accept rebates that came from middlemen (suppliers). It seems likely that customers were more willing to accept money from the company than from other donors becausc they believed the company had higher income. 相似文献

Based on ethnographic research from Sri Lanka on post-tsunami recovery and displacement due to war, this article examines how emotions may have impacted on the research process and how the research participants (researcher, affected people, and partners) construct knowledge in crisis situations. The author discloses her own emotions while researching crisis and also explores the emotions that prevail among research participants in collaborations. Emotions are understood as mental and cultural constructions which unfold in the interaction between individuals and the world. A key driver for the author has been her commitment to those who suffer, which explains her willingness to take risk. It is argued that researchers who make themselves vulnerable to emotions not only make research more engaging and intelligible, but also provoke reflections. In places of crisis, both fluidity and pervasiveness of disillusionment prevail. Building on emotionally sensed knowledge of the research participants in such places, additional insights may be gained and new methods of discovery may be developed. A prerequisite for such a research agenda is a high level of trust and honesty among participants during fieldwork and beyond. 相似文献
