Primeness, Internalism and Explanatory Generality

Williamson (2000) [Knowledge and its Limits, Oxford: Oxford University Press] argues that attempts to substitute narrow mental states or narrow/environmental composites for broad and factive mental states will result in poorer explanations of behavior. I resist Williamson’s arguments and use Twin-Earth style cases to argue for the causal inertness of broad mental states.     

Knowledge About Genetics Among African Americans

Although knowledge about genetic concepts is important for individuals to be active participants in medical technologies that use genetic science, limited information is available on knowledge about basic genetic concepts and terminology in African Americans. The purpose of this study was to evaluate knowledge about general genetic concepts and medical genetics terminology among African Americans and to identify factors having independent associations with knowledge. Participants were 109 adult African Americans enrolled in a study on attitudes about race, genetics, and smoking. The majority of respondents were knowledgeable about general genetic concepts, but were less knowledgeable about medical genetics terminology. Education was the only factor independently associated with knowledge about sporadic disorders in multivariate logistic regression analysis. Respondents with at least some college education were most likely to be knowledgeable about sporadic disorders (OR=2.70, 95% CI=1.10, 6.67, p=.03). The results of this study suggest that genetics education targeted to African Americans may need to focus on increasing understanding about technical concepts related to genetics.     

幼儿反事实推理的发展特点及影响因素

本研究以北京某幼儿园94名幼儿为被试,采用图片故事法和口语报告相结合的方式,考查了幼儿反事实堆理能力的发展特点及影响因素。结果表明：（1）4、5岁幼儿的表现明显好于3岁幼儿,但是4、5岁幼儿之间没有明显差异;（2）问题形式和因果链对反事实推理的影响上具有交互作用;（3）领域知识在各年龄阶段上对反事实推理的影响存在差异。     

弗洛姆的道德认识理论

弗洛姆的道德认识理论建立在对人的研究的基础上。认识善、恶以及道德规范,主要是对人性以及蕴含在人性中的可能性的认识。由于人是有生命的,处于不断的生成过程中,因此,对人的认识必须打破客观主义的认识模式,认识主体打破与对象之间的鸿沟,实现融合合一,以整个的内在体验对象,从而获得如对象本来所是的样子去认识对象。弗洛姆的体验性知识在强调人的主观情感投入到认识中的同时,认为认识对象是外在实在的,知识是普遍性有效的,因而是一种客观的认识。弗洛姆的道德认识理论与认识论的实践转向的暗相契合。     

Diffusion,Decolonializing, and Participatory Action Research

Miki Takasuna describes knowledge transfer between elite communities of scientists, a process by which ideas become structurally transformed in the host culture. By contrast, a process that we have termed knowledge transfer by de-elitization occurs when (a) participatory action researchers work with a community to identify a problem involving oppression or exploitation. Then (b) community members suggest solutions and acquire the tools of analysis and action to pursue social actions. (c) Disadvantaged persons thereby become more aware of their own abilities and resources, and persons with special expertise become more effective. (d) Rather than detachment and value neutrality, this joint process involves advocacy and structural transformation. In the examples of participatory action research documented here, Third World social scientists collaborated with indigenous populations to solve problems of literacy, community-building, land ownership, and political voice. Western social scientists, inspired by these non-Western scientists, then joined in promoting PAR both in the Third World and in Europe and the Americas, e.g., adapting it for solving problems of people with disabilities or disenfranchised women. Emancipatory goals such as these may even help North American psychologists to break free of some methodological chains and to bring about social and political change.

Attenuation of attention bias in obsessive-compulsive disorder

Cognitive theories of obsessive-compulsive disorder (OCD) suggest that the disorder is characterized by an attention bias towards personally relevant threatening material. However, existing research on attention bias in OCD has yielded conflicting findings. One possibility that might account for the null findings is that attention bias may diminish over the course of the experiment. The present study tested this hypothesis using a visual dot-probe task with idiographic word selection. Results from our study confirmed that individuals with OC symptoms show an attention bias towards idiographically selected, threatening information in the first block of trials, and that the degree of this bias is correlated with the severity of OC symptoms. The temporal pattern of attention bias over the course of the experiment was consistent with our hypothesis. A comparison of early and late blocks of trials revealed an attenuation of attention bias in individuals with OC symptoms, potentially reflecting habituation to threatening information over the course of the experiment.     

Core knowledge and its limits: The domain of food

Adults, preschool children, and nonhuman primates detect and categorize food objects according to substance information, conveyed primarily by color and texture. In contrast, they perceive and categorize artifacts primarily by shape and rigidity. The present experiments investigated the origins of this distinction. Using a looking time procedure, Experiment 1 extended previous findings that rhesus macaques (Macaca mulatta) generalize learning about novel food objects by color over changes in shape. Six additional experiments then investigated whether human infants show the same signature patterns of perception and generalization. Nine-month-old infants failed to detect food objects in accord with their intrinsic properties, in contrast to rhesus monkeys tested in previous research with identical displays. Eight-month-old infants did not privilege substance information over other features when categorizing foods, even though they detected and remembered this information. Moreover, infants showed the same property generalization patterns when presented with foods and tools. The category-specific patterns of perception and categorization shown by human adults, children, and adult monkeys therefore were not found in human infants, providing evidence for limits to infants’ domains of knowledge.     

Detecting and predicting changes

When required to predict sequential events, such as random coin tosses or basketball free throws, people reliably use inappropriate strategies, such as inferring temporal structure when none is present. We investigate the ability of observers to predict sequential events in dynamically changing environments, where there is an opportunity to detect true temporal structure. In two experiments we demonstrate that participants often make correct statistical decisions when asked to infer the hidden state of the data generating process. However, when asked to make predictions about future outcomes, accuracy decreased even though normatively correct responses in the two tasks were identical. A particle filter model accounts for all data, describing performance in terms of a plausible psychological process. By varying the number of particles, and the prior belief about the probability of a change occurring in the data generating process, we were able to model most of the observed individual differences.     

Reviving inert knowledge: analogical abstraction supports relational retrieval of past events

We present five experiments and simulation studies to establish late analogical abstraction as a new psychological phenomenon: Schema abstraction from analogical examples can revive otherwise inert knowledge. We find that comparing two analogous examples of negotiations at recall time promotes retrieving analogical matches stored in memory—a notoriously elusive effect. Another innovation in this research is that we show parallel effects for real-life autobiographical memory (Experiments 1–3) and for a controlled memory set (Experiments 4 and 5). Simulation studies show that a unified model based on schema abstraction can capture backward (retrieval) effects as well as forward (transfer) effects.
