The indexicality of ‘knowledge’

Epistemic contextualism—the view that the content of the predicate ‘know’ can change with the context of utterance—has fallen into considerable disrepute recently. Many theorists have raised doubts as to whether ‘know’ is context-sensitive, typically basing their arguments on data suggesting that ‘know’ behaves semantically and syntactically in a way quite different from recognised indexicals such as ‘I’ and ‘here’ or ‘flat’ and ‘empty’. This paper takes a closer look at three pertinent objections of this kind, viz. at what I call the Error-Theory Objection, the Gradability Objection and the Clarification-Technique Objection. The paper concludes that none of these objections can provide decisive evidence against contextualism.     

3～5岁幼儿在主题-规则冲突条件下的类比推理

本研究采用经典类比任务,考察了3～5岁幼儿在主题-规则冲突条件下类比推理发展的水平与特点.结果表明:(1)在无主题联想条件下,幼儿的单维类比推理在3～4岁迅速发展,4～5岁发展较为平缓,而双维类比推理在3～5岁仍处于较低水平.(2)在主题—规则冲突条件下,幼儿在单维类比推理中表现出一定的主题联想优势反应;幼儿在双维类比推理中表现出较强的主题联想优势反应,年龄特点为:3岁幼儿有较强的主题联想优势反应,4岁幼儿的主题联想优势反应明显下降,而5岁幼儿又表现出较强的主题联想优势反应.     

“直觉调整差误”偏向对贝叶斯推理成绩的影响

采用贝叶斯推理问题作为实验材料,探讨被试解决贝叶斯推理问题的启发式策略,从认知偏向的角度分析该问题的困难原因。结果发现:(1)贝叶斯推理问题解决过程中的可得性启发与后验概率估计过程中的直觉调整差误密切相关;(2)贝叶斯推理问题解决过程中文、理科被试都同样会产生直觉调整差误偏向;(3)贝叶斯推理问题解决过程中的后验概率估计值和对推理问题中包括虚报率信息的命题的可得性测量所得主观概率之间存在显著的负相关。     

Triangulating Political Responsibility: The Motivated Formation of Responsibility Judgments

This article analyzes the process through which partisan bias arises during the formation of citizens' judgments of political responsibility. Informed by theories of motivated political reasoning, it argues that exposure to partisan cues motivates partisans to pursue directional goals, goals which bias the cognitive processing of information and, in turn, overall judgments of responsibility. It further argues that the nature of this biased processing will be such that partisans devalue information inconsistent with their partisan affect. Using a pair of experiments, I test these hypotheses by manipulating both objective evidence concerning gubernatorial responsibility for a state's fiscal imbalance and the presence of partisan cues. Findings support both sets of expectations. The results also suggest that the effects of partisan bias are greater in judgments tied to institutional actions than in those tied to institutional roles and expectations.     

Punishing Those Responsible for the Prison Abuses at Abu Ghraib: The Influence of the Negative Reciprocity Norm (NRN)

The negative reciprocity norm (NRN) is the personal moral code specifying retaliation as a proper response to wrongdoing ( Eisenberger, Lynch, Aselage, & Rohdieck, 2004 ). We examined the role of negative reciprocity in interpreting and reacting to the prison abuses at Abu Ghraib. Results showed that people who believed that American soldiers behaved wrongly at Abu Ghraib were more likely to view punishing the soldiers responsible as a highly moral response and were less likely to contribute money to a charitable organization that helps American soldiers. These relationships were only present among those highly endorsing the negative reciprocity norm.     

We Value What Values Us: The Appeal of Identity-Affirming Science

Members of the public (Study 1; n =  184) and university students (Study 2; n =  101) evaluated a piece of research and indicated their support for its continuation. The research findings were held constant, but the methods that revealed those findings were attributed to either neuroscience or social science, and the conclusions based on those findings were biased either in favor of men or in favor of women. Study 1 revealed that participants were more positive about research that affirmed their gender identity and that was based on neuroscience rather than social science. Study 2 found this pattern to be apparent in more specialist samples. Indeed, participants with some scientific training were more influenced by research that affirmed the reader's gender identity. Participants with less scientific training, in comparison, were more influenced by the type of science described when making judgments about the value of the research. Contrary to popular claims, this suggests that scientific knowledge alone is no protection against the effects of bias on research evaluation. Implications for the practice and popularization of science are discussed.     

Monotonicity and Reasoning with Exceptions

A proposal by Ferguson [2003, Argumentation 17, 335–346] for a fully monotonic argument form allowing for the expression of defeasible generalizations is critically examined and rejected as a general solution. It is argued that (i) his proposal reaches less than the default-logician’s solution allows, e.g., the monotonously derived conclusion is one-sided and itself not defeasible. (ii) when applied to a suitable example, his proposal derives the wrong conclusion. Unsuccessful remedies are discussed.     

The Logic of Critique

This paper attempts to define the concept of critique, explain its function␣and properties and distinguish it from the close concept of evaluation. It is argued that, beyond the argument, a critique is concerned with the position of the proponent relatively to the reality the argument is about. Moreover, a critique is itself an argument in which assumptions regarding the position of the proponent are justified for a given audience on the basis of the proponent’s argumentative background within a specific domain.     

知识图式对贝叶斯推理的影响

选取具有概率知识的大学生(专家)和没有概率知识的大学生(新手)为被试,进行贝叶斯推理中的概率估计,探讨知识图式对贝叶斯推理的影响。结果表明,具有概率知识背景的大学生比没有概率知识背景的大学生概率估计的准确性更高,反应时更长,说明知识图式影响概率信息的搜索和判断。     

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。
