体验型消费和实物型消费的差异：研究方法及效应

体验型消费是指以获得一种体验为目的的消费行为, 而实物型消费为以获得某种实质物品为目的的消费行为, 以往研究发现这两种不同的消费类型在消费者心理以及行为的多个维度上的影响都存在差异。本文首先回顾了过往研究所采用的研究方法并整理为如下三类：对消费类型的操纵方法、消费类型偏好的测量方法以及非实验研究方法。并从心理与行为两个角度, 梳理了体验型消费和实物型消费影响的差异。未来研究需进一步关注影响不同消费类型的前因变量, 充分利用新兴数据获取方式、关注不同消费类型的模型建构和内部维度, 以及体验型消费可能存在的“阴暗面”。     

Event-based prospective remembering in a virtual world

Most laboratory-based prospective memory (PM) paradigms pose problems that are very different from those encountered in the real world. Several PM studies have reported conflicting results when comparing laboratory- with naturalistic-based studies (e.g., Bailey, Henry, Rendell, Phillips, & Kliegel, 2010 Bailey, P. E., Henry, J. D., Rendell, P. G., Phillips, L. H. and Kliegel, M. 2010. Dismantling the “age-prospective memory paradox”: The classic laboratory paradigm simulated in a naturalistic setting. Quarterly Journal of Experimental Psychology, 63: 646–652. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar]). One key contrast is that for the former, how and when the PM cue is encountered typically is determined by the experimenter, whereas in the latter case, cue availability is determined by participant actions. However, participant-driven access to the cue has not been examined in laboratory studies focused on healthy young adults, and its relationship with planned intentions is poorly understood. Here we report a study of PM performance in a controlled, laboratory setting, but with participant-driven actions leading to the availability of the PM cue. This uses a novel PM methodology based upon analysis of participant movements as they attempted a series of errands in a large virtual building on the computer screen. A PM failure was identified as a situation in which a participant entered and exited the “cue” area outside an errand related room without performing the required errand whilst still successfully remembering that errand post test. Additional individual difference measures assessed retrospective and working memory capacity, planning ability and PM. Multiple regression analysis showed that the independent measures of verbal working memory span, planning ability, and PM were significant predictors of PM failure. Correlational analyses with measures of planning suggest that sticking with an original plan (good or bad) is related to better overall PM performance.     

The interplay between presentation material and decision mode for complex choice preferences

Recent research suggests that, when faced with a choice between several alternatives described with a large number of attributes, people make better choices if they do not consciously ponder over the alternatives but rather perform a distraction task assumed to elicit unconscious thought. Subsequent research attempting to replicate this finding, however, provided mitigated support for its existence. The research reported here contributes to this ongoing debate on two grounds. First, it highlights a methodological confound between qualitative and quantitative presentation material and proposes a novel procedure that can accommodate both. Second, it shows that, whereas conscious deliberation leads to better decisions when alternatives are characterised by quantitative information, the use of a qualitative format for presenting information cancels the advantage of conscious deliberation.     

Influence of body-centered information on the transfer of spatial learning from a virtual to a real environment

This study investigated the effects of body-centred information on the transfer of spatial learning using a wayfinding task and tasks that specifically probe the route and survey strategies of navigation. The subject learned a route in either a real or a virtual environment (VE; 3D scale model of a Bordeaux neighbourhood) and then reproduced it in the real environment. The involvement of body-based information was manipulated across the spatial learning conditions in the VE: participants learned with full body-based information (treadmill with rotation), with the translational component only (treadmill without rotation) or without body-based information (joystick). In the wayfinding task, the results showed a significant effect of the learning environment with the best scores obtained in the real and treadmill with rotation conditions. There was no significant difference between these two conditions, but the real condition was significantly different from the treadmill without rotation and joystick conditions. Also, the visual flow was sufficient to successfully perform the two egocentric tasks used as well as a direction estimation task (a survey task), in so far as there is no significant difference between the joystick and the treadmill conditions. By contrast, the distance estimates were improved by the treadmill condition including the translational component (but not the rotational component). Finally, our results show that treadmill with rotation promotes the transfer of spatial learning from a virtual to a real environment (compared to joystick and treadmill without rotation). Moreover, body-centred informations are more involved in allocentric (distance estimates) than egocentric navigational strategies.     

Fonagy and Freud. Psychological versus psychic reality

Peter Fonagy and Mary Target present their Playing with reality theory as a developmental theory centred on the concept of psychic reality. This paper compares Fonagy and Target's use of the concept of psychic reality with Freud's original concept. It is argued that the concept of psychic reality has been redefined from delineating a psychic reality stemming from the unconscious to denoting a kind of conscious or preconscious psychological reality characterized by an experience of equality between the internal and the external worlds. The theoretical discussion is illustrated by being applied to eating disorder pathology, which by Fonagy and colleagues is described as associated with thought processes characterized by psychic reality.     

“The primary process”: The vicissitude of a concept

Abstract

During the first twenty years that Freud spent creating his theory, he assumed that most of the functions responsible for creating mental-thought structures were organized according to two different forms or principles of thought. He called these forms “primary process” and “secondary process”. The “secondary process” is identified with rational thinking and the ego, and it is easy to follow the changes that this concept underwent in the works of Freud that followed. The concept of “primary process”, on the other hand, disappeared from his later works with no explanation. This article traces the changes that the “primary process” underwent in Freud's thinking and examines the connection between his analytical technique and his research method. A close study of the changes that the “primary process” underwent reveals that Freud's developmental thought process included concepts whose directional changes may be termed “regressive”.     

On psychic reality and neutrality: Empathy and the work of construction in countertransference

Abstract

The clinical challenges faced in encountering patients who do not fit the standard treatment of Oedipus conflicts clearly show the limitations of the interpretative method, thus making indispensable the study of clinical concepts and techniques as a way to broaden the psychoanalytic horizons. In order to analyse the different psychopathological problems resistant to traditional clinical approaches, it is necessary to reorganise the technique on the basis of a better understanding of the ways in which subjectivity is rooted in early psychic constitution. In this way, empathy becomes important as a clinical tool. The use of empathy must be understood as a decisive factor in handling clinical cases and situations in which the treatment encounters obstacles that restrict the power of the analyst's verbal interventions.In this case, can we say that the use of empathy interferes directly with and changes the position of the concept of psychic reality? Moreover, as we use empathy, can we also say that the concept of neutrality is transformed, without being abandoned? The intention of this paper is to discuss these questions using clinical material taken from the analysis of borderline clinical cases and situations.     

Effectiveness of virtual reality distraction during a painful medical procedure in pediatric oncology patients

The effectiveness of virtual reality (VR) as a behavioral intervention designed to decrease distress during port access procedure was examined in 20 7- to 14-year-old pediatric oncology patients. Children were randomized to either engage in an immersive VR environment during the procedure or to a no VR control condition. Children's distress was assessed through subjective self-ratings and objective physiological and behavioral ratings. Narrative accounts of the experience were used as a measure of how well the child coped with the procedure. VR was effective in reducing children's distress on all measures. Implications of these findings for intervention are discussed.     

Wentzel–Kramers–Brillouin solution of cut-off frequency for horizontal shear (SH) waves in various inhomogeneous thin films

The Wentzel–Kramers–Brillouin method is employed to study the cut-off frequencies of the horizontal shear waves in a freestanding functionally graded piezoelectric–piezomagnetic material film with the electrically and magnetically open boundary conditions. An analytical solution, which could be used in analyzing the problems of various functionally graded materials, is proven to have high precision by analytical analysis and a numerical example. The results reveal that the set of cut-off frequencies is a series of approximate arithmetic progressions. A theoretical foundation based on the relationship between the cut-off frequencies and the materials’ gradient property is established for nondestructive evaluation.     

The Virtual Kitchen Challenge: preliminary data from a novel virtual reality test of mild difficulties in everyday functioning

ABSTRACT

Background: Efficient, objective measures of mild functional difficulties are lacking. Preliminary data from a novel, non-immersive virtual reality, performance-based task (Virtual Kitchen Challenge; VKC) were obtained to address this gap.

Methods: 14 older and 21 younger adults completed cognitive tests and two everyday tasks (breakfast, lunch) in the VKC with virtual objects and a touch-screen and in the Real Kitchen with real objects (order counterbalanced). Automated performance measures were obtained from the VKC program and human coders scored VKC and Real Kitchen videos for errors.

Results: Older adults made more errors than younger adults on the VKC and Real Kitchen, with similar error patterns across measures. VKC automated measures were significantly related to measures from human coders, performance on the Real Kitchen, and cognitive test scores.

Conclusion: The VKC is a valid and highly efficient performance-based measure of subtle functional difficulties with great potential for future clinical and research applications.
