This study investigates the effects of formal order and spatial content on reasoning in three dimensions in view of the Formal Rules theory and the Mental Models theory of spatial reasoning. Twenty‐six subjects solved 144 spatial deductive problems that varied by the formal order of the entities (referential order, referential continuity) and the spatial content (dimension, orientation, and direction). There were two dependant variables: the correct responses and their response times. The number of mental models and the formal derivations underlying the deductions allowed comparison of opposite predictions made by the Formal Rules theory and the Mental Models theory of spatial reasoning. The results overwhelmingly supported the Mental Models theory's predictions. The effects of referential order showed that problems yielding two possible mental models were significantly more difficult than problems based on one mental model, although the former problems involved a shorter formal derivation than the latter. The effects of referential continuity also generalized the Mental Models theory's prediction to reasoning in all three dimensions. The effects of referential continuity showed that problems that required independent layouts in memory were reliably more difficult than problems that allowed the continuous integration of the entities in a mental model. We obtained these results despite the fact that the former condition required a shorter formal derivation than the latter. The effects of spatial content were also reliable despite the fact that the formal derivations were the same across spatial content. Thus, spatial deductions were significantly easier to make in 1D than in 2D and in 2D than 3D. Deductions were also significantly easier to make from left to right along the horizontal axis of a mental model, and from top to bottom along the vertical axis rather than from the respective opposite directions. The effects of spatial content suggest that mental models reproduce spatial relations relative to reference frames. 相似文献

Occupational stress adversely affects productivity, absenteeism, and job turnover, and contributes to health-related problems. The effects of organizational level and gender on the specific sources of occupational stress assessed by the Job Stress Survey (JSS) were evaluated for a heterogeneous sample of 1,791 working adults (860 males, 931 females) employed in 2 industrial companies and a large state university. Significant main or interactive effects of organizational level and/or gender were found for the JSS Item Index, Severity and/or Frequency scores of 29 of the 30 JSS items. Organizational level effects were both more numerous and larger in magnitude than gender effects. Employees at higher organizational levels reported that they experienced stress more often while making critical decisions and dealing with crisis situations than did workers at lower levels, for whom inadequate salary and lack of opportunity for advancement were more stressful. For males, work stress was more strongly related to concerns about their role in the power structure of an organization, whereas female employees reported experiencing more severe stress when there was a conflict between job requirements and family relationships. 相似文献

This article explores a variety of personal and professional boundary issues encountered by seminary faculty. The authors contend that boundary crossing is inevitable in contemporary theological education, which is structured such that professors engage in multiple roles with students as they attend to the education of the whole person. Guidelines are reviewed for minimizing risk to students and professors. Topics include life as a community member, student‐faculty friendship, and romantic relationships. Attention to work/life balance is seen as critical to the prevention of misconduct. The article ends with a call for continued conversation as well as institutional accountability and change. 相似文献

Many educators and developmental psychologists have pointed to the development of symbolic thought and representational abilities as a set of fundamental capacities that underlie the development of self-regulation, problem solving, planning, and higher level thought processes. While many early childhood programs value children's development of symbolic capacities, three approaches, High/Scope, Tools of the Mind, and Reggio Emilia, were analyzed in terms of one context from the array of strategies and experiences that characterizes the approach in order to examine the distinctive way that three different preschool programs apply the theoretical construct of representational development to pedagogical strategies. 相似文献

We examined understanding of the title Ms ., in college students and individuals surveyed via the Internet. Participants were asked to define Ms. and other titles, and rate the likely marital status and age of those using the titles. While some participants indicated that Ms. was a title for women of any marital status, a common alternative definition of Ms. was a title for unmarried women. Younger participants (those under 20) were significantly more likely to use this definition. We also asked what title women preferred for themselves. Older unmarried women were more likely to prefer Ms. as their own title than were younger unmarried women, while married women overwhelmingly preferred the use of Mrs . Perhaps this is why many younger people assume that Ms. is a title for unmarried women too old to use Miss . 相似文献
