Consumer Perception and Evaluation of Waiting Time: A Field Experiment

We varied telephone waiting times for a commercial service in 2 different experiments. In the 1st experiment, the telephone rate was either 0 or fixed at Dfl 1 (approximately $0.40) per minute. Consumer perceptions of waiting times could be described best by a psychophysical power function. Furthermore, wait evaluations were mainly influenced by the difference between the consumers’ acceptable and perceived waiting times. The negative effect of perceived waiting time on wait evaluations was increased by the monetary costs of waiting. In the 2nd experiment, the waiting times were filled in different ways: with music, queuing information, and information about expected waiting time. Information about the expected waiting time significantly reduced the overestimation of waiting time, although it increased the negative effect of perceived waiting time on wait evaluations.     

Reasonable reasons for waiting

Recent decision‐making research claims to establish that, in violation of Savage's normative sure‐thing principle, individuals often wait to acquire noninstrumental information and subsequently base their decisions upon this information. The current research suggests that characterizing individuals as pursuing noninstrumental or useless information may be overstated. Through a series of experiments we establish, first, that many people choose to wait, even when waiting provides no additional information at all. Second, the longer people are allowed to wait before having to decide, the more people prefer to wait rather than decide immediately. Third, those individuals who choose to wait are the ones less confident about committing themselves to a decision. For them, the benefit from waiting may be especially valuable by allowing them to come to terms with a less‐than‐ideal decision. Copyright © 2003 John Wiley & Sons, Ltd.     

When waiting to choose increases patience

We explore how waiting to choose influences patience. We propose that waiting to make an intertemporal choice increases the assumed value of the items for which people are waiting, leading them to become more patient. Five studies support this model. Study 1 finds that after waiting to choose, people exhibit greater patience than if they had not waited or before they had started to wait. Studies 2a and 2b find that increased valuation (rather than decreased cost of the wait) mediates the impact of waiting on patience. Study 3 further finds that whereas waiting to choose increases preference for a larger-later (over smaller-sooner) item, it also increases willingness to pay to expedite delivery of a single item. Finally, study 4 shows the waiting effect is stronger for hedonic than for utilitarian products. These studies modify existing theory by identifying the conditions under which waiting to choose can improve patience.     

社会支持与人格对大学生压力的影响

将横断与纵向研究相结合,对660名大学生进行了问卷调查。结果发现,社会支持对同期压力的主效应非常显著,对后期压力的主效应则不显著。社会支持的变化类型对后期压力也具有显著的主效应。“开朗—果断”与“拘谨—温和”两类人格对同期压力的主效应非常显著,前者同期的各类压力均显著低于后者的同类压力;前期人格类型对两年后压力的主效应依然显著。社会支持与人格的独立主效应和交互作用均显著;社会支持的变化与人格的独立主效应和交互作用均显著     

An “Opting In” Paradigm for Kidney Transplantation

Almost 60,000 people in the United States with end stage renal disease are waiting for a kidney transplant. Because of the scarcity of organs from deceased donors live kidney donors have become a critical source of organs; in 2001, for the first time in recent decades, the number of live kidney donors exceeded the number of deceased donors. The paradigm used to justify putting live kidney donors at risk includes the low risk to the donor, the favorable risk-benefit ratio, the psychological benefits to the donor, altruism, and autonomy coupled with informed consent; because each of these arguments is flawed we need to lessen our dependence on live kidney donors and increase the number of organs retrieved from deceased donors.

An “opting in” paradigm would reward people who agree to donate their kidneys after they die with allocation preference should they need a kidney while they are alive. An “opting in” program should increase the number of kidneys available for transplantation and eliminate the morally troubling problem of “organ takers” who would accept a kidney if they needed one but have made no provision to be an organ donor themselves. People who “opt in” would preferentially get an organ should they need one at the minimal cost of donating their kidneys when they have no use for them; it is a form of organ insurance a rational person should find extremely attractive.

An “opting in” paradigm would simulate the reciprocal altruism observed in nature that sociobiologists believe enhances group survival. Although the allocation of organs based on factors other than need might be morally troubling, an “opting in” paradigm compares favorably with other methods of obtaining more organs and accepting the status quo of extreme organ scarcity. Although an “opting in” policy would be based on enlightened self-interest, by demonstrating the utilitarian value of mutual assistance, it would promote the attitude that self-interest sometimes requires the perception that we are all part of a common humanity.     

Self‐Directed Learning Favors Local,Rather Than Global,Uncertainty

Collecting (or “sampling”) information that one expects to be useful is a powerful way to facilitate learning. However, relatively little is known about how people decide which information is worth sampling over the course of learning. We describe several alternative models of how people might decide to collect a piece of information inspired by “active learning” research in machine learning. We additionally provide a theoretical analysis demonstrating the situations under which these models are empirically distinguishable, and we report a novel empirical study that exploits these insights. Our model‐based analysis of participants' information gathering decisions reveals that people prefer to select items which resolve uncertainty between two possibilities at a time rather than items that have high uncertainty across all relevant possibilities simultaneously. Rather than adhering to strictly normative or confirmatory conceptions of information search, people appear to prefer a “local” sampling strategy, which may reflect cognitive constraints on the process of information gathering.     

On simulating one-trial learning using morphological neural networks

“Learning once, remembering forever”, this wonderful cognitive phenomenon sometimes occurs in the learning process of human beings. Psychologists call this psychological phenomenon “one-trial learning”. The traditional artificial neural networks can simulate the psychological phenomenon of “implicit learning”, but can’t simulate the cognitive phenomenon of “one-trial learning”. Therefore, cognitive psychology gives a challenge to the traditional artificial neural networks. From two aspects of theory and practice in this paper, the possibility of simulating this kind of psychological phenomenon was explored by using morphological neural networks. This paper takes advantage of morphological associative memory networks to realize the simulation of “one-trial learning” for the first time, and gives 5 simulating practical examples. Theoretical analysis and simulation experiments show that the morphological associative memory networks are a higher effective machine learning method, and can better simulate the cognitive phenomenon of “one-trial learning”, therefore provide a theoretical basis and technological support for the study of intelligent science and cognitive science.     

A Psychological Typology of Newly Unemployed People for Profiling and Counselling

Profiling of the unemployed in order to predict and prevent long-term unemployment has hitherto been based on socio-professional data; however, there is evidence that psychological dimensions also predict job search strategies and unemployment duration. In order to provide psychological profiling, a typological method could be more parsimonious than trait/dimension approaches. Typologies created to date have not addressed the issue of predicting employment status. A sample of 384 newly unemployed people was assessed using psychometric scales which have been shown in past research to be linked to job finding. Through cluster analysis, five groups of unemployed people were differentiated: the “integrated”, “willing”, “outsider”, “anxious”, and “dispossessed”. The typology showed predictive validity for employment status after 12 months. People who were “anxious” or “dispossessed” were more often unemployed than those who were “integrated”, “willing”, or “outsider”. It provided an alternative way of classifying unemployed people that could be used in profiling and especially in advisory support and counselling.     

The just world hypothesis as an argumentative resource in debates about unemployment benefits

The concept of the “just world” is established as a key explanation for how people make sense of inequality so that those deemed to score high in belief in a just world are more likely to hold prejudicial beliefs and to blame people in poverty for their situations. However, this is an inadequate explanation for such complicated and controversial issues. To better understand talk about the just world and the controversial issue of the distribution of unemployment benefits (an issue of inequality), a discursive psychological approach to the just world is used. Therefore, a discourse analysis focusses on 2 feature length British televised discussions about benefit claimants called “The Big Benefit Row: Live” (Channel 5 3/2/2014) and “Benefits Britain: the Debate” (Channel 4 17/2/2014). The analysis demonstrates that people draw on both just and unjust world arguments simultaneously and also topicalise what counts as just so as to support their positions on unemployment benefits, rather than in the consistent way that just world theory would predict. It is therefore argued that the just world should be recast as a cultural value that facilitates arguments about benefits, rather than an internally held belief.     

Stress and recurrent miscarriage

Our current understanding into the role of stress in unexplained recurrent miscarriages comes from two different research strategies. The majority of research has examined the role of psychological support within this patient population. This support has been provided in a number of ways ranging from weekly interviews with a psychiatrist or gynaecologist and or visual re-assurance in the form of ultrasound scans. A comparison of psychological support with an absence of such intervention has found differences in successful pregnancy outcome varying from as great as 84 versus 26%, respectively. It has been assumed that psychological support reduces the miscarriage rate by reducing “stress”within this patient population. In addition it provides indirect support for a role of stress in the aetiology of unexplained recurrent miscarriage. Other studies have attempted to directly assess the effect of personality characteristics on miscarriage rate; these studies have yielded conflicting results.The mechanism by which stress may be causal in the aetiology of unexplained recurrent miscarriage has not been examined in humans. Animal studies, however, have found that psychological distress can alter immune parameters that may be intricately involved with implantation. These parameters include an elevation of the “abortive” cytokine TNF-a and a reduction in the “anti-abortive” cytokine TGF-P2. Cells that are involved in the release of TNF-a at the feto-maternal interface include T cells, macrophages and mast cells.Mechanisms through which stress may act on these cells are explored and an integrated model is postulated.     

Self-Other Discrepancies in Waiting Time Decisions

Both anecdotal evidence and recently reported research suggest that people are risk-averse when faced with waiting time decisions. Four studies investigate whether there is a self-other discrepancy in how people make waiting time decisions themselves and how they predict others will make similar decisions. People are found to believe that others have valuations of time similar to their own. However, when faced with alternatives that involve risk in the duration of the wait, the results point to a self-other discrepancy, in that people report greater risk-aversion themselves than they think others would. Further, when faced with waiting time gains, people are themselves more risk-averse than they think others would be. Conversely, when faced with waiting time losses, people are themselves more risk-seeking than they think others would be. Overall, the results are consistent with the recently proposed risk-as-feelings hypothesis.

A dynamic view of cultural influence: A review

Static models of culture's influence have given way to a dynamic view, which identifies not only differences across cultures in people's judgments and decisions, but also the situations and conditions in which these differences do or do not appear. Theory and evidence developed from a cognitive psychological perspective underlie this dynamic approach, including research emerging from the “dynamic constructivist” and “situated cognition” models. In the present review, we focus on findings that confirm the utility of this cognitively oriented approach, and briefly discuss the advantages and complementary nature of the “social collective” and neuroscience approaches to understanding culture.     

Pratiques d’encadrement et usages des TIC : un exemple en Gendarmerie nationale

This article will present the results of field research conducted in a French army civilian body responsible for the safety of property and people. The object of study concerns “e-leadership” management practice in connection with the information technology and communication (ICT). After recalling the role played by ICT in situations of current work, the issue of management relationship will be developed, as well as knowledge on the “e-leadership”. The results show the impact of ICT on the management relationship is rooted in a multiple determinism related to the nature of tasks, the characteristics of technological tools and constraints in the use situations.     

Eine Schule für das Leben mit Schizophrenie

Schizophrenia usually appears in young people at an age when they are about to leave home, i.e. at a life stage which is already difficult without a psychological disorder. The “learning by doing” program of “Pension Bettina”, which is described here, supports the affected persons and their families in the process of detachment from home and coping with the disorder. Special emphasis is laid on the difficult balance between increasing the autonomy of the affected person and providing adequate familial support.     

Chimpanzee (Pan troglodytes) anticipation of food return: coping with waiting time in an exchange task

Despite controversial expectations that animals achieve reciprocal altruism, it is unclear if nonhuman species possess the necessary cognitive abilities. For reciprocal altruism, individuals must anticipate the loss of a commodity and accept a delay before some return. The authors investigated the abilities of 5 chimpanzees (Pan troglodytes) to cope with increasing waiting duration in exchange tasks. Subjects had to keep a small cookie before returning it to a human partner to obtain a larger piece. For a piece 2, 4, or 8 times the size of the small piece, 3 of the 5 subjects waited for up to 4 min. For a piece 40 times larger, 4 of the 5 subjects waited up to 8 min. At long time lag, renouncement to wait occurred earlier than predicted by subjects' general waiting capacity, suggesting that the decision to wait was based on a trade-off between reward quantity and expected costs of the waiting duration. Chimpanzees could anticipate a delayed reward at a time scale of several minutes. If this reflects a cognitive limit in chimpanzees' anticipation capacity, reciprocal altruism by keeping track of costs and benefits over extended periods may be unlikely in chimpanzees.     

奏响长者的“生命质量”凯歌

“健康老龄化”的探索中, 指标的定义至关重要。“生命质量”综合了生理、心理、社会、环境等多维度指标, 优于“预期寿命”、“健康预期寿命”等传统概念, 其定义在发展中被广为接受, 强调个体自评的主观性、可塑性和多维度。促进积极心理因素的干预是改善老年生命质量的有效路径。老龄化过程虽必然伴随生理系统衰退, 但心理系统积极参与, 仍能为年长者奏响生命质量的凯歌。     

An Extension of Osuna's Model for Stress Caused by Waiting

In an attempt to model the accumulation of stress caused by waiting, Osuna (1985) postulated that anxiety stems from a perceived harm or loss to the person's well being that he represented by an increasing function of the total time to service. This paper proposes an extension of this model to situations in which the psychological cost of waiting is not functionally related to time but merely correlated with it. It is shown that the properties of Osuna's model recently reexamined by Suck and Holling (1997) remain valid in this broader framework. Copyright 2001 Academic Press.     

The Tripartite Foundations of Temporal Psychological Distance: Metaphors,Ecology, and Teleology

What is psychological distance? Why do events sometimes seem “close” yet other times seem “ages away?” We propose a tripartite model of the foundations of psychological distance in which: (a) people use spatial distance as a metaphor for psychological distance; (b) the ecology of subjective experiences that coincide with changes in objective distance define, and hence, influence psychological distance; (c) psychological distance is shaped in the service of people's ultimate goals, or teleological considerations, of successfully navigating through time. This model implies that the subjective experiences that are typically associated with reductions in objective temporal distance should reduce temporal psychological distance–the subjective sense of how close or far away events are. We review evidence indicating that emotional arousal, attention, fluency, and motivational considerations all reduce psychological distance. This model also implies a temporal asymmetry in which people prioritize thinking about the future, which approaches in time, over thinking about the past, which recedes in time. Consequently, the future is psychologically closer than the past, people attend more to the future than to the past, and people feel more emotionally aroused about the future than about the past. These findings help advance understanding of psychological distance as a distinct psychological construct.     

The Relative Importance of Ethnicity: Ethnic Categorization among Older Children

In this study the relative importance of ethnic categories is investigated among Dutch and Turkish children (10 to 12 years of age). Children were asked to categorize and indicate preferences with respect to eight hypothetical contemporaries in different situations that were described by a combination of ethnicity, gender, and a psychological characteristic (“expressed affect or smartness”). The results show, first, that children preferred to use psychological characteristics for categorization. Second, the use of ethnic categories was domain-dependent: Ethnicity was used less often in indicating preferences for playing than preferences for working on an educational task and for explaining quarrels. Third, the use of ethnic categories was affected by stereotypes. It is concluded that the widely accepted idea that ethnicity plays a central role in the judgements of children in multi-ethnic situations seems overstated.
