Inhibiting beliefs demands attention

Research across a variety of domains has found that people fail to evaluate statistical information in an atheoretical manner. Rather, people tend to evaluate statistical information in light of their pre-existing beliefs and experiences. The locus of these biases continues to be hotly debated. In two experiments we evaluate the degree to which reasoning when relevant beliefs are readily accessible (i.e., when reasoning with Belief-Laden content) versus when relevant beliefs are not available (i.e., when reasoning with Non-Belief-Laden content) differentially demands attentional resources. In Experiment 1 we found that reasoning with scenarios that contained Belief-Laden content required fewer attentional resources than reasoning with scenarios that contained Non-Belief-Laden content, as evidenced by smaller costs on a secondary memory load task for the former than the latter. This trend was reversed in Experiment 2 when participants were instructed to ignore their beliefs when reasoning with Belief-Laden and Non-Belief-Laden scenarios. These findings provide evidence that beliefs automatically influence reasoning, and attempting to ignore them comes with an attentional cost.     

The law of large numbers in children's diversity-based reasoning

Adults increase the certainty of their inductive inferences by observing more diverse instances. However, most young children fail to do so. The present study tested the hypothesis that children's sensitivity to instance diversity is determined by three variables: ability to discriminate among instances (Discrimination); an intuition that large numbers of instances increase the strength of conclusion (Monotonicity); ability to detect subcategories and evaluate numerical differences between the subcategories, or Extraction. A total of 219 Chinese children aged 6 to 11 were tested for sensitivity to diversity by means of Discrimination, Monotonicity, and Extraction. The results indicated that children at all ages were able to discriminate instances and attend to set size. However, only 9- and 11-year-olds demonstrated Extraction and sensitivity to diversity. Furthermore, among all children diversity scores increased linearly with the level of Extraction. These results suggest that the law of large numbers plays a role in children's diversity-based reasoning.     

认知风格、内外向性、情绪稳定性与图形推理效果的关系

采用EFT、EPQ和RSPM-CR量表对156名理科大学生进行测量研究,结果发现：场独立性认知风格在图形系统变化、系列关系、抽象推理方面,较场依存性有明显优势;情绪稳定性高者图形推理的总体效果显著优于情绪稳定性低者;内向性者与外向性者的图形推理效果无显著差异;认知风格、情绪稳定性与图形推理总分有显著正相关,认知风格的正向预测力居首位。     

Global Justice for Humans or for all Living beings and what Difference it Makes

I begin with an account of what is deserved in human ethics, an ethics that assumes without argument that only humans, or rational agents, count morally. I then take up the question of whether nonhuman living beings are also deserving and answer it in the affirmative. Having established that all individual living beings, as well as ecosystems, are deserving, I go on to establish what it is that they deserve and then compare the requirements of global justice when only humans are taken into account with the requirements of global justice when all living beings are taken into account.     

On Using Ethical Theories to Teach Engineering Ethics

Many engineering ethics classes and textbooks introduce theories such as utilitarianism and Kantianism (and most others draw from these theories without mentioning them explicitly). Yet using ethical theories to teach engineering ethics is not devoid of difficulty. First, their status is unclear (should one pick a single theory or use them all? does it make a difference?) Also, textbooks generally assume or fallaciously ‘prove’ that egoism (or even simply accounting for one’s interests) is wrong. Further, the drawbacks of ethical theories are underestimated and the theories are also otherwise misrepresented to make them more suitable for engineering ethics as the authors construe it, viz. the ‘moral reasoning’ process. Stating in what various theories disagree would allow the students to frame the problem more productively in terms of motive–consequence or society–individual dichotomies rather than in terms of Kant–utilitarian.     

Reward Systems,Moral Reasoning,and Internal Auditors’ Reporting Wrongdoing

This study investigates the issue of whistle-blowing behavior that results from internal auditors discovering company wrongdoing in the process of preparing financial information. An experiment was conducted to examine whether reward systems such as cash incentives or employment contracts have an impact on auditors’ disclosing wrongdoing behavior. The results indicate that internal auditors are more likely to report wrongdoing to higher authorities when incentives are provided, suggesting reward systems have a positive effect on disclosing company’s wrongdoing or even fraud. In addition, the result reveals that internal auditors with lower levels of moral reasoning are more sensitive to cash incentives.     

The psychology of meta-ethics: exploring objectivism

How do lay individuals think about the objectivity of their ethical beliefs? Do they regard them as factual and objective, or as more subjective and opinion-based, and what might predict such differences? In three experiments, we set out a methodology for assessing the perceived objectivity of ethical beliefs, and use it to document several novel findings. Experiment 1 showed that individuals tend to regard ethical statements as clearly more objective than social conventions and tastes, and almost as objective as scientific facts. Yet, there was considerable variation in objectivism, both across different ethical statements, and across individuals. The extent to which individuals treat ethical beliefs as objective was predicted by the way they grounded their ethical systems. Groundings which emphasize the religious, pragmatic, and self-identity underpinnings of ethical belief each independently predicted greater ethical objectivity. Experiment 2 replicated and extended these findings with a refined measure of ethical objectivism. Experiment 3 demonstrated the robustness of the religious grounding of ethics, and differentiates it from mere religious belief and from political orientation. The results shed light on the nature of ethical belief, and have implications for the resolution of ethical disputes.     

条件推理中的二元效应初探

通过预备实验选取前件(或后件)是二元(或多元)的5种条件命题的4种推理形式作为实验材料,以大学本科生为被试,考察了五种不同条件命题类型对4种推理结果的影响.结果表明命题类型、推理规则以及两者的交互作用都非常显著.这个结果进一步验证了条件推理的集合映射模型.     

工作记忆对类比推理的影响

该实验采用2(类比推理类型)×6(组别)双因素实验设计来探讨工作记忆与类比推理之间的关系,尤其关注工作记忆的各个子成分对类比推理的影响。控制组的被试只需完成类比推理测验,而实验组的被试是在双任务的条件下进行实验。结果表明,工作记忆是影响类比推理的一个重要因素。在图形类比推理中,主要有视空间模板中的空间成分,语音回路中的发音成分以及中央执行器的参与;在言语类比推理中,则是视空间模板中的空间成分起主要作用。
