Modeling the Impact of Control on the Attractiveness of Risk in a Prospect Theory Framework

Many decisions involve a degree of personal control over event outcomes, which is exerted through one's knowledge or skill. In three experiments we investigated differences in decision making between prospects based on a) the outcome of random events and b) the outcome of events characterized by control. In Experiment 1, participants estimated certainty equivalents (CEs) for bets based on either random events or the correctness of their answers to U.S. state population questions across the probability spectrum. In Experiment 2, participants estimated CEs for bets based on random events, answers to U.S. state population questions, or answers to questions about 2007 NCAA football game results. Experiment 3 extended the same procedure as Experiment 1 using a within-subjects design. We modeled data from all experiments in a prospect theory framework to establish psychological mechanisms underlying decision behavior. Participants weighted the probabilities associated with bets characterized by control so as to reflect greater risk attractiveness relative to bets based on random events, as evidenced by more elevated weighting functions under conditions of control. This research elucidates possible cognitive mechanisms behind increased risk taking for decisions characterized by control, and implications for various literatures are discussed.     

发展地看待知识内隐性的判别方法：内隐与外显学习区分的新途径

知识内隐性的判别一直是内隐学习研究领域的研究重点之一,恰当的区分内隐被试和外显被试对于该类研究有着至关重要的意义。本文介绍知识内隐性判别问题的研究历史,由最初的主观标准和客观标准到后来改进的研究方法,指出了随着对待内隐和外显学习两者关系的理论的发展,研究方法有必要与时俱进,并提出了新的区分内隐被试和外显被试的新方法。相对于传统研究方法,新方法从内隐知识和外显知识互为补充、＂任何一种学习即存在内隐学习,也存在外显学习＂的理论指导下,通过被试的猜测水平来判断其内隐水平,并确定＂纯的＂内隐被试的标准。该方法发展地看待内隐学习及其与外显学习的关系,有助于研究者更加深入、精确地研究内隐学习的相关问题。     

Mediating between international knowledge and local knowledge: The critical role of local field officers in an HIV prevention intervention

The outcomes of health interventions are co‐constructed through negotiation between the competing knowledges of different stakeholders. In such a context, local implementing partners – who mediate between international donors/programme managers and local beneficiary communities – have a critical ‘knowledge brokering’ role to play. With appropriate support, they can facilitate integration of internationally established knowledge with local beliefs and practices in ways that support health‐enhancing behaviour change. This paper focuses on the local field officers of an HIV prevention programme with Cambodian military couples. The paper asks: (1) what are the outcomes of knowledge encounters between international organizations and local field officers, as expressed in field officers' interpretation of programme goals, strategies and messages? (2) To what extent does the intervention context support the field officers' knowledge brokering efforts? Data collected includes semi‐structured interviews, observations of programme meetings and activities, and textual materials. The findings demonstrate that field officers privilege international knowledge, particularly in interactions with international manager–partners. However, in the field, they both hybridize programme messages and struggle to resolve dilemmas provoked by conflicting international and local knowledges. Material and symbolic asymmetries within the intervention context are shown to undermine their knowledge brokering efforts, as field officers attempt to claim identities and futures as health development professionals. Implications for programme practices and accountability systems are discussed. Copyright © 2010 John Wiley & Sons, Ltd.     

Detecting conscious awareness from involuntary autonomic responses

Can conscious awareness be ascertained from physiological responses alone? We evaluate a novel learning-based procedure permitting detection of conscious awareness without reliance on language comprehension or behavioural responses. The method exploits a situation whereby only consciously detected violations of an expectation alter skin conductance responses (SCRs). Thirty participants listened to sequences of piano notes that, without their being told, predicted a pleasant fanfare or an aversive noise according to an abstract rule. Stimuli were presented without distraction (attended), or while distracted by a visual task to remove awareness of the rule (unattended). A test phase included occasional violations of the rule. Only participants attending the sounds reported awareness of violations and only they showed significantly greater SCR for noise occurring in violation, vs. accordance, with the rule. Our results establish theoretically significant dissociations between conscious and unconscious processing and furnish new opportunities for clinical assessment of residual consciousness in patient populations.     

Career-choice readiness in adolescence: Developmental trajectories and individual differences

Developing career-choice readiness is an important task in adolescence, but current theory and research has provided a rather static view of the phenomenon. The present study investigated the development of career-choice readiness among a group of 325 Swiss students assessed four times every 5 months from seventh through eighth grade. A variable-centered approach applying latent curve modeling showed not only a linear increase of readiness over time but also significant inter-individual differences in the level and development of readiness. Higher levels were predicted by more self-esteem and generalized self-efficacy and fewer perceived barriers while increase in readiness was predicted by increase in occupational information. A person-centered approach applying latent class-growth analysis identified four distinct developmental trajectories: high-increasing (42%), high-decreasing (5%), moderate-increasing (42%), and constantly low (11%). Students with different trajectories showed significant differences in core self-evaluations, occupational knowledge, and barriers. The results suggest that environmental demands promote a developmental trend in readiness development that overrules individual differences for the majority of students. Individual differences affect the level of readiness to a greater extent than the process of its development. Career information seems pivotal for readiness increase.     

Forms of Reflection,Imagination, and the Love of Wisdom

This article reflects upon the relationship between philosophy and theology. It further considers the persisting relevance of the specifically Hellenic inheritance of philosophy as contemplation and the Delphic exhortation, “Know thyself!” It concludes with reflections upon the role of imagination in relation to the philosophical idea of God as the supreme and transcendent causal principle of the physical cosmos.     

When promoting a charity can hurt charitable giving: A metacognitive analysis

Charities need to come to mind to enter a potential donor's consideration set. However, feeling familiar with a charity and its cause can facilitate or impair giving. In most cases, perceived good memory for details of the cause fosters the impression of personal importance, which increases giving (Studies 1 and 3). But when the charity aims to increase awareness of a cause, good memory for the cause suggests that awareness is already high, which impairs giving (Studies 2 and 3). Hence, promotions for awareness-raising charities can actually have negative consequences, confirming the predictions of a metacognitive analysis.     

Whose memories are they and where do they go? Problems surrounding internalization in children on the autistic spectrum

Recent work in neuroscience has highlighted the contrast between 'procedural' memory for bodily experiences and skills, which is unconscious though unrepressed, and verbalizable, 'declarative' memory, which includes autobiographical memory. Autobiographical memory is weak in people with autistic spectrum disorder, who frequently turn to self-generated sensations for reassurance that they continue to exist. The author suggests that, instead of internalizing shared experiences leading to growth, children with autism can feel that they add to themselves by taking over the qualities of others through the 'annexation' of physical properties that leads to a damaged object and can trigger a particular sort of negative therapeutic reaction. Clinical illustrations drawn from the treatment of two children on the autistic spectrum illustrate some ramifications of these processes in relation to the sense of a separate identity and the capacity to access memories.     

A Study of the Opinions of College Students

ABSTRACT

When judging whether a relationship partner can be counted on to “be there” when needed, people may draw upon knowledge structures to process relevant information. We examined one such knowledge structure using the prototype methodology: indicators of a partner who is likely to be there when needed. In the first study (N = 91), the structure, content, and reliability of the prototype of indicators were examined. Then, using a false recognition study (N = 77), we demonstrated that once activated, the prototype of indicators of a partner who is likely to be there when needed affects information processing. Thus, the prototype of indicators may shape how people process support-relevant information in everyday life, affecting relationship outcomes. Using this knowledge structure may help a person process relevant information quickly and with cognitive economy. However, it may also lead to biases in judgments in certain situations.
