Exploring the conjunction fallacy within a category learning framework

The literature presents two major theories on the cause of the conjunction fallacy. The first attributes the conjunction fallacy to the representativeness heuristic. The second suggests that the conjunction fallacy is caused by people combining p(A) and p(B) into p(A&B) in an inappropriate manner. These two theories were contrasted in two category‐learning experiments. As predicted by the latter theory, data showed that participants that could assess p(A&B) directly made fewer conjunction fallacies than participants who had to compute p(A) and p(B) separately and then combine them into p(A&B). Least conjunction fallacies were observed in the cases where the representativeness heuristic was applicable. Overall, data showed that an inability to appropriately combine probabilities is one of the key cognitive mechanisms behind the conjunction fallacy. Copyright © 2008 John Wiley & Sons, Ltd.     

原型表征对创造性问题解决过程中的启发效应的影响

以32个科学发明创造问题为实验材料, 采用“学习8个原型-测试8个问题”的两阶段实验范式, 通过操纵原型学习条件(是否有标识或插图)考察了原型的知识表征对创造性问题解决的启发效应的影响, 结果发现：1)标识对原型的激活率在无插图水平上有显著影响, 有标识比无标识原型的激活率更高, 在有插图水平上无显著影响; 插图对原型的激活率有显著影响, 有插图比无插图原型的激活率更高。2)标识和插图都对问题解决的正确率有显著影响, 有标识比无标识正确率更高, 有插图比无插图正确率更高。3)标识和插图在原型激活率和问题解决正确率上都存在显著交互作用, 反映出原型启发的思维过程是复杂的, 表现出灵活性、经济性的特点。     

对整合模型和占优启发式模型的检验：基于信息加工过程的眼动研究证据

基于信息加工过程视角, 本研究采用眼动技术检验风险决策整合模型和占优启发式模型。结果表明, 自主决策任务条件下决策过程反应时及信息搜索模式均不同于期望价值(EV)迫选任务条件下的决策过程反应时及信息搜索模式; 自主决策任务条件下决策过程反应时并未随着选项间整体值(CPT值)差值的变大而变快, 且基于特征(attribute-based)的信息搜索多于基于选项(option-based)的信息搜索, 不符合整合模型预期。此外, 决策者亦未按照占优启发式模型所假定的决策步骤进行决策。基于信息加工过程的检验结果既不利于以累积预期理论为代表的整合模型, 亦不利于占优启发式模型。文章建议从决策过程视角检验已有决策模型及建立新的启发式决策过程模型(process model)。     

阶段转移事件对公平稳定性的影响

摘要：目前,组织公平的研究多集中于组织公平与组织结果变量之间关系,较少关注组织公平的稳定性。本文采取4（公平模式：公平控制/初始公平/不公平控制/初始不公平）×2（实验阶段：阶段1/阶段2）混合实验设计,探讨阶段转移事件对被试公平反应稳定性的影响。研究结果显示,公平对待导致积极的公平反应,不公平对待导致消极的公平反应;公平程序向不公平程序的转移导致对实验者信任和组织公民行为意向的评价显著降低;而不公平程序向公平程序的转移并没有导致对实验者信任和组织公民行为意向评价的显著增加,从而说明了公平反应的有限稳定性。     

The alternative explanation to the alternative‐outcome effect and the detection of the focal outcome effect

Abstract: Previous studies on subjective probability judgment indicate that pair‐wise comparison between the focal and the strongest alternative outcome plays an important role in probability judgment. This study, however, found that the randomness of alternative outcomes affected probability judgment for focal outcome. In the present study, 182 participants provided probability estimates for winning on hypothetical slot machines where both successes and losses were composed of multiple outcomes. The randomness of both the focal and alternative outcomes were defined by the expression used in Rappoport and Budescu (1997 ). The analysis indicated that the more random the distributions of both focal and alternative outcomes, the higher the estimated probability for focal outcome. Some theoretical suggestions are discussed.     

The meaning of ‘reconstruction’ within the lived experience of mastectomy for breast cancer

This paper represents a heuristic study of the meaning and essence of ‘reconstruction’ within the lived experience of mastectomy for breast cancer. Open‐ended interviews were conducted with a sample of eight women aged 40 to 58 years, who underwent mastectomy for breast cancer. Four participants had immediate breast reconstruction; two participants had delayed breast reconstruction, and two participants decided not to have the procedure. The study demonstrates that themes of loss/change/reconstruction are inextricably linked to the experience of mastectomy. Loss of a breast was likened to bereavement and in some women caused a loss of part of their identity. The closeness of death altered the awareness the women had of their time left on earth. This awareness brought about change/reconstruction in the majority of the women, in their lives and in their relationships with others. Prior to breast reconstruction there is a place for exploring with women the meaning of ‘normal’ and ‘whole’. Implications for counselling are discussed.     

Reinforcement,Rationality, and Intentions: How Robust Is Automatic Reinforcement Learning in Economic Decision Making?

Reinforcement learning is often observed in economic decision making and may lead to detrimental decisions. Because of its automaticity, it is difficult to avoid. In three experimental studies, we investigated whether this process could be controlled by goal intentions and implementation intentions. Participants' decisions were investigated in a probability‐updating task in which the normative rule to maximize expected payoff (Bayes' rule) conflicted with the reinforcement heuristic as a simple decision rule. Some participants were asked to set goal intentions designated to foster the optimization of rational decision making, while other participants were asked to furnish these goal intentions with implementation intentions. Results showed that controlling automatic processes of reinforcement learning is possible by means of goal intentions or implementation intentions that focus decision makers on the analysis of decision feedback. Importantly, such beneficial effects were not achieved by simply instructing participants to analyze the feedback, without defining a goal as the desired end state from a first‐person perspective. Regarding intentions supposed to shut down reinforcement processes by controlling negative affect, effects were more complex and depended on the specified goal‐directed behavior. The goal intention to suppress the disappointment elicited by negative feedback was not effective in controlling reinforcement processes. Furnishing this goal with an implementation intention even backfired and strengthened unwanted reinforcement processes. In contrast, asking participants to keep cool in response to negative decision outcomes through the use of goal intentions or implementation intentions increased decisions in line with Bayes' rule.

The Cognitive Underpinnings of Continuous Identity: Higher Episodic Memory Recall and Lower Heuristic Usage Predicts Highest Levels of Self-Continuity

Continuous identity (CI) is a sense of persistent identity wherein the present self is seen as overlapping with the past and future selves. This study addressed the hypothesis that judgments of CI require successful retrieval of information by examining the relationship between varying levels of CI and two forms of memory recall. The pattern of findings indicated that high levels of cued memory recall combined with low levels of heuristic usage were associated with higher levels of CI, and this occurred for both past-to-present CI and present-to-future CI. We propose that to achieve high levels of CI, individuals need to access and analyze a fund of stored autobiographical information.
