The automated cockpit: A comparison of attitudes towards human and automated pilots

Automation is being used extensively in aviation, particularly in the aircrafts themselves. The airline industry benefits from automation because it often increases efficiency and performance. To date, automation research has focused largely on operator trust and reliance, while largely ignoring the role of affect and trust in shaping the attitudes of the novice consumer. In two studies, we found that participants rated a human pilot more favorably than an auto-pilot. However, attitudes toward the automated pilot were more favorable in a high priced compared to a low priced ticket condition, indicating that participants used price to infer quality. In Study 2, inducing positive affect increased ratings of an automated pilot. Path analyses provided additional evidence that perceptions of automation are largely influenced by feelings.     

记忆源检测的双加工机制研究

本研究借鉴Mitchell等人的图词归源和早晚归源任务,引发启发式和系统式加工,并引入知觉流畅性变量,试图在知觉层面上分离两种加工的底层工作模式。结果发现:(1)源检测具有相对脆弱性,成绩显著差于再认。(2)启发式加工和系统式加工在加工速度和底层工作模式上分离,启发式加工速度快,其工作模式似乎是对刺激的知觉流畅性进行阈下水平的解释与归因,而系统式加工速度慢,其工作模式似乎是对意义的分析与推理。

It takes two to tango: Research and practice as an amazing dance

This paper offers an appreciative critique of Kim Etherington's recent book, Narrative Approaches to Working with Adult Male Survivors of Male Child Sexual Abuse. I discuss the issues raised in the book with reference to one of my current clients. Etherington does not produce new substantive theory: the power of this work is in the narrative. Her important contribution lies in the reflexivity with which she encounters her material. The use of critical reflexivity challenges the subject/object dichotomy inherent in much positivistic research, and presents a much‐needed approach to process that is congruent with the lived experience of counselling. I would suggest that research is more likely to succeed in informing practice if the material is open to personal interpretation by the reader/therapist. Further, I would claim that the activity of using research creatively is itself a heuristic process: useful learning is most likely to occur if the dialogic relationship with the client and therapist is mirrored in the relationship between the therapist and the research text.     

Should I Drive Today? Development of a daily driving decisions model for older adults

BackgroundOlder adults in communities make daily decisions about how to meet their transportation needs so they can access services and stay socially connected. With the aging of populations in developed countries, the travel decisions of older adults will have increasing impacts. Research studies have identified different sets of factors that contribute to certain travel decisions, but little research has been directed towards understanding how individuals select information from all available factors, what information they include in their decisions under different circumstances, and the processes they use in making their transportation decisions.MethodsThis exploratory study involved 20 men and 17 women, mean age 78.6 years (range 70–96), who drove weekly. All participants were involved in each phase of the 3-phase study. In Phase 1, a review of the literature and interviews with the participants was used to collect information, and inductive thematic analysis was employed to construct a draft conceptual model of older driver decision-making. In Phase 2, participants completed a stated preference task of written scenarios to demonstrate their decision-making strategies. Results were tabulated and used to refine a final Daily Driving Decisions model. In Phase 3, a card sorting decision task was used to test the model with participants.ResultsThe final dynamic Daily Driving Decisions Model was confirmed to describe decision processes used by the participants in making decisions about how they would meet their transportation needs. The model describes three categories of factors used in decisions, labelled Motivators, Constraint/Enablers and Context, each containing four attribute themes. A significant finding was the variable use of the same item to either constrain or enable the decision to drive depending on the variation of other factors in the scenario. Participants demonstrated use of compensatory and noncompensatory (heuristic, habitual) decision processes that were accommodated by the model.ConclusionThe proposed Daily Driving Decisions Model addresses a gap in our understanding of how older drivers make their decisions about meeting their transportation needs. The model presents a template for classifying the types of information used, ignored or discarded by older adults, and the pathways that they take to arrive at their decisions. The model provides opportunities for further research in testing the influence of other factors such as urban/rural residence, income, health status and culture on driving decisions. Further, the model can be used by practitioners to gain insight into the decision-making behaviours of individuals and to develop interventions to enhance their decision-making skills.     

Emotional reactions to scandals: When does moral character make a difference?

A scandal can evoke public outrage when it is widely publicized and involves an individual who is perceived to have a high level of cultural representativeness. Two experiments showed that when the scandalous target's moral character was highlighted, emotional responses towards the target were least negative when the scandal was widely circulated and when the target was seen as a representative of his culture. These results suggest that when a cultural symbol is implicated in a widely‐circulated scandal, the negative emotions directed towards the scandalous individual can be alleviated when the public remains confident in his or her commitment to morality.     

消费决策中羊群行为的心理机制

羊群行为是消费市场上的一种典型现象,它是指在不确定情境中,消费者模仿他人进行消费决策的行为。本研究通过模拟消费情境对消费者羊群行为的心理机制进行研究。研究1通过操纵观点的强弱研究消费者的信息加工方式。结果发现,消费者的羊群行为是消费者采用一致性启发式或能力启发式的结果。研究2进一步通过操纵群体内部的一致性程度考察两种启发式的作用条件。结果表明,在群体内部一致性程度高的情况下,消费者倾向于采用一致性启发式,与大众决策保持一致;在群体内部一致性低的情况下,消费者倾向于采用能力启发式,与专家的决策保持一致。     

启发式在警觉任务中的交叉复合作用

通过对个体和团队和警觉任务的阶段性研究,本研究发现了启发式对个体警觉任务的交叉复合作用,个体在警觉任务关键信号出现时绩效不一定下降。关键信号出现时成绩的升降取决于关键信号与背景信号的可取性。另外,团队结构克服了个体决策中出现的信息不全和信息加工资源不足的缺陷,使警觉任务在关键事件发生时、发生前和发生后的成绩波动不大。     

Beyond grounded theory: The use of a heuristic approach to qualitative research

The grounded theory approach has become established as the qualitative methodology of choice for many counselling and psychotherapy researchers. It is now becoming apparent to many researchers that there are significant difficulties associated with defining what the grounded theory method actually is, and how is should be implemented. In addition, its popularity has tended to keep other qualitative approaches under‐explored and under‐utilised. This paper explores some of the methodological issues raised by the grounded theory approach, before presenting and then contrasting heuristic inquiry as a very different but equally useful form of qualitative methodology. Finally, the notion of researcher as bricoleur will be considered in the light of the need to develop pluralistic approaches to qualitative research in counselling and psychotherapy.     

The affect heuristic and the attractiveness of simple gambles

Prior studies have observed that the attractiveness of playing a simple gamble (7/36 to win $9; otherwise win nothing) is greatly enhanced by introducing a small loss (7/36 win $9; otherwise lose 5¢). The present studies tested and confirmed an explanation of this finding based on the concept of evaluability and the affect heuristic. Evaluators of the “no‐loss” gamble lack a precise feeling for how good $9 is, hence give it little weight in their judgment. In the second gamble, comparison with the small loss makes $9 “come alive with feeling” and become weighted in the judgment, thus increasing the attractiveness of the gamble. These results demonstrate the importance of contextual factors in determining affect and preference for simple risk‐taking opportunities. They show that the meaning, utility, and weighting of even a very familiar monetary outcome such as $9 is not fixed, but depends greatly on these contextual factors.
