虚拟环境和WWW设计中的心理学研究

虚拟环境和互联网技术的应用极大地推动了计算机技术的发展,同时也产生了若干人因素问题。其中,虚拟环境中的“沉浸度”、“迷路”以及相关导航方式的设计等尤为突出。众多研究表明,在虚拟环境和WWW(World Wide Web)中,合理地呈现信息、恰当地布置浏览环境以及科学地设计导航方式,使人-计算机界面符合用户的认知加工特点和能力,减少认知负荷和心理压力,这对于最大程度地提高虚拟环境的沉浸度、减少迷路现象具有重要意义。     

A Report on a Four-Year Longitudinal Study of Intellectual Development of Engineering Undergraduates

As part of an investigation into the effects of curricular reforms in the undergraduate program in the College of Engineering, a series of Perry-style interviews were conducted over a 4-year period. The study was undertaken in an attempt to assess the impact of collaborative design-based engineering courses that were being implemented. Students who completed the collaborative design course in their first year were higher on the Perry scale than their peers who did not. However, this effect was not sustained through the rest of the curriculum, as more traditional courses dominated. No statistically significant change in Perry position was observed for students in their 1st and 3rd years; however, a growth of approximately one Perry position was observed between the 3rd and 4th years. The relationship of current curricula to this pattern of intellectual development is discussed, and arguments for altering the curriculum to support intellectual development are made.     

Shifting worldviews: modeling sacrality in naturalistic perspective

ABSTRACT

In this essay, I offer an exercise in modeling a multifaceted concept of sacrality. I do so within the context of my increasing interest in naturalistic, evolutionary views of human social behavior. I distinguish four genres of behavior and their ethological trajectories where sacrality can thus be re-contextualized, at the same time freeing the term from its essentialized versions in religious studies. The behavioral frames include: making-sacred as dedicating objects for secure respect, defending the subsequent social order from violation, attributing status or prestige to objects, and responding to sacred ‘prompts’ with commensurate actions within niche-specific environments.     

Operative Group Dynamics in School Settings: Structuring to Enhance Educational, Social, and Emotional Progress

This article will describe the dynamics taking place in school settings, particularly in classrooms. Literature pertaining to the use of group dynamics in classrooms will be presented. A number of significant group therapy concepts will be addressed. These will include group-as-a-whole, group structure, transference-countertransference, the school and the classroom as holding environments, and therapeutic factors. Some practical dynamic strategies that are meant to strengthen group operations in classroom will also be included. The article will be guided by the writer's personal experiences within school settings and classrooms.     

Empirical evaluation of virtual environment technology as an experimental tool in developmental spatial cognition research

The study compared developmental aspects of spatial knowledge acquisition in a real and a virtual large-scale environment according to the classical study of Cohen and Schuepfer (1980 Cohen, R. and Schuepfer, T. 1980. The representation of landmarks and routes. Child Development, 51: 1065–1071. [Crossref], [Web of Science ®] , [Google Scholar]) with 40 younger children (7–8 years old), 40 older children (11–12 years old), and 40 adults. All participants learned the correct route through a maze, recalled the inherent landmarks, and drew a map of the maze. The results revealed equivalent age effects for these tasks in the real and the virtual world. In both conditions younger children needed more trials to learn the route and showed less configurational knowledge than older children and adults. Age group performance on landmark recollection did not differ in either the virtual or the real world maze. Except for the map drawing task performance was always worse in the virtual world condition. Because the developmental process was comparable in real and virtual environments, the results support the use of virtual environments for the research on developmental aspects of spatial knowledge.     

Deriving Training Strategies for Spatial Knowledge Acquisition From Behavioral,Cognitive, and Neural Foundations

While much has been made of the potential uses for virtual environment (VE) technologies as training aids, there are few guidelines and strategies to inform system development from the user’s perspective. Assumptions are that a human factors-based evaluation will ensure optimal performance, transferring training from virtual to real worlds; however, there are complex, yet unexplored, issues surrounding system optimization and employment. A comprehensive investigation into the foundations of training, traversing levels of performance analysis, from overt behavioral responses to the less explicit neuronal patterns, is proposed from which optimal training strategies can be inferred and system development guidelines deduced.     

With Liberty and Some Justice for a Few: Thinking Theologically about Criminal Justice

The current crisis in the American criminal justice system begs for theological response, and its sources need theological critique. The recent proposed statement of the ELCA draws attention to the needs of victims of crime and their families, and makes sensible recommendations for paths to greater justice. In doing so it is important to remember what forms of justice are possible under the jurisdiction of fallible, earthly institutions.     

The backstage of urban ambiances: When atmospheres pervade everyday experience

This paper explores a new way of designing and experimenting with the city. How are we to conceptualize the changes in contemporary cities on the basis of their ambiances? What about the sensory and emotional production of urban territories? What is at stake when our aim is no longer to design space but also to install an atmosphere? In order to answer such questions, rather than offering a formal definition of what an ambiance may be, I intend to show from what it proceeds, on what it is based, what it produces and transforms in urban life. The focus is exploring five ambiance operating modes in the province of urban design: establishing the sensory as a field of action, composing with affective tonalities, giving consistency to urban situations, maintaining spaces over time and playing with imperceptible transformations. Each of these operating modes can account for how a physical environment manages to become a lived ambiance, how a world of built forms manages to become a world of sensory atmospheres. Starting with the sensory environment itself, I show how it is increasingly becoming a domain of design and research. Then I emphasize on the role of affect in everyday urban situations and daily social activities. Thirdly I explore the pervasive character of an ambiance and question its capacity to unify an experience. I continue by pointing out the temporal dynamic of an ambiance and the necessity to sustain a sense of continuity of the environment. Finally I emphasize on the importance of micro-phenomena in the quality and immersive power of an ambiance. These five operating modes of ambiance enables us to focus on the very ordinary sensory fabric of urban life and its issues.     

Learning from experience in nonlinear environments: Evidence from a competition scenario

We test people’s ability to learn to estimate a criterion (probability of success in a competition scenario) that requires aggregating information in a nonlinear manner. The learning environments faced by experimental participants are kind in that they are characterized by immediate, accurate feedback involving either naturalistic outcomes (information on winning and/or ranking) or the normatively correct probabilities. We find no evidence of learning from the former and modest learning from the latter, except that a group of participants endowed with a memory aid performed substantially better. However, when the task is restructured such that information should be aggregated in a linear fashion, participants learn to make more accurate assessments. Our experiments highlight the important role played by prior beliefs in learning tasks, the default status of linear aggregation in many inferential judgments, and the difficulty of learning in nonlinear environments even in the presence of veridical feedback.
