Knowledge despite falsehood

I examine the claim, made by some authors, that we sometimes acquire knowledge from falsehood. I focus on two representative cases in which a subject S infers a proposition q from a false proposition p. If S knows that q, I argue, S's false belief that p is not essential to S's cognition. S's knowledge is instead due to S's belief that p′, a proposition in the neighbourhood of p that S (dispositionally) believes (and knows). S thus knows despite her false belief. The widely accepted and plausible principle that inferential knowledge requires known premises is unscathed.     

Performance on auditory and visual temporal information processing is related to psychometric intelligence

The present study investigated the relationship between psychometric intelligence and temporal resolution power (TRP) as simultaneously assessed by auditory and visual psychophysical timing tasks. In addition, three different theoretical models of the functional relationship between TRP and psychometric intelligence as assessed by means of the Adaptive Matrices Test (AMT) were developed. To test the validity of these models, structural equation modeling was applied. Empirical data supported a hierarchical model that assumed auditory and visual modality-specific temporal processing at a first level and amodal temporal processing at a second level. This second-order latent variable was substantially correlated with psychometric intelligence. Therefore, the relationship between psychometric intelligence and psychophysical timing performance can be explained best by a hierarchical model of temporal information processing.     

Relation of occupational knowledge to career interests and competence perceptions in Italian children

The relations of differential occupational knowledge with interests and competence perceptions in children as well as how these relations were moderated by gender and grade were examined in this study using an Italian sample. Data were collected from samples of elementary school and middle school children (N = 539). The Inventory of Children's Activities—Revised (ICA-R; Tracey & Ward, 1998) was used to assess children's interest and competency perceptions in various activities associated with the Holland's RIASEC types. The Occupational Knowledge Scale (OKS) was created for this study, and consisted of a representative sampling of occupational titles to which children indicated their knowledge. Hierarchical regression results indicated a relationship between knowledge, interests, and competence perceptions in children. With regard to overall knowledge, no relationship was found between general knowledge and either grade or gender. More specific examination of the type of knowledge as it varied across the dimensions of People–Things, and Data–Ideas demonstrated that there appeared to be a specific pattern relating interest, gender, and grade to knowledge of occupations. For knowledge of people relative to things occupations, higher interest, higher grade level, and being female predicts stronger knowledge of people occupations. It was also found that interest in ideas predicts stronger knowledge of ideas occupations, and being male predicts stronger knowledge of high prestige occupations. Generally, competence perceptions did not have a unique relation with one's knowledge of People–Things, Ideas–Data, or Prestige; however, girls who reported higher competence had greater knowledge of ideas occupations.     

Exploring an integrative model of infant behavior: what is the relationship among temperament, sensory processing, and neurobehavioral measures?

Traditionally, developmental psychology, occupational/physical therapy, and behavioral pediatrics view similar infant behaviors from temperament, sensory processing, or neurobehavioral theoretical perspectives. This study examined the relations between similar and unique summary scores of three infant assessments (Early Infancy Temperament Questionnaire - EITQ, the Infant Sensory Profile - ISP, and the NICU Network Neurobehavioral Scale - NNNS) in a healthy sample of 100, one-month-old infants. A Principal Components Analysis of selected subscale scores derived from the three assessments suggested a three-factor model. Temperament and sensory summary scores had the strongest relations on two factors: Sensory-Affective Reactivity and Engagement. A third factor had strong relations between state regulation and motor competence. This new integrative model also validates an existing model and expands explanation of infant behavior across disciplines and methods which have significant implications for assessment, intervention, and management practices.     

Are historic years understood as numbers or events? An fMRI study of numbers with semantic associations

While numbers generally cue processing of quantity or order, they can also contain semantic information, as in the case of historic years (e.g., “1492” calls forth associations of Columbus sailing the ocean blue). Whether these dates are processed as quantities or events may depend on the context in which they occur. We examined such “ambiguous number” processing in two different contexts using a paired-comparison task, recording both behavioral responses and brain activity. Participants were either asked to think of all items as numbers and to choose the larger number, or were told to treat the comparators as events and to choose the later event. Behaviorally, all events showed a normal distance effect, establishing that they may be understood and compared in an ordinal sequence. Functional magnetic resonance imaging (fMRI) demonstrated significant differences between years when treated as numbers versus as events. Dates in both contexts shared activity in parietal lobe regions previously implicated in number processing. Dates as numbers showed no extra-numeric activity, while dates thought of as events evoked activity in temporal semantic processing and frontal semantic retrieval areas. These differences suggest that extra-numeric information may be easily accessed and incorporated during processing when supported by even a weak context. This work supports previous studies showing a dissociation between quantity and meaning, and illustrates the brain areas involved in these different aspects.     

小学低年级汉语儿童语素意识、汉字识别和词汇知识的发展关系——交叉滞后研究

以146名小学一年级儿童为研究对象, 进行了历时2年的3次追踪测试, 考察小学生从一到三年级的语素意识、汉字识别和词汇知识之间发展关系的变化。在控制了语音意识、快速命名、正字法意识、一般认知能力和自回归效应后, 结果发现：(1)一年级时的汉字识别显著预测二年级的同音语素意识和同形语素意识; (2)一年级时的词汇知识显著预测二年级的复合语素意识和汉字识别; (3)二年级时的汉字识别和词汇知识对三年级的同音语素意识、同形语素意识和复合语素意识均有显著预测作用; (4)二年级时的同形语素意识对三年级的词汇知识具有显著预测作用。结果表明, 小学一至三年级的汉字识别和词汇知识对语素意识具有预测作用; 三种语素意识对汉字识别和词汇知识的预测作用中, 只有同形语素意识能够显著预测词汇知识; 三种语素意识、汉字识别和词汇知识的发展关系存在变化且具有阶段性特点。     

Skepticism,naturalism, pyrrhonism

Skepticism and naturalism bear important connections with one another. Do they conflict or are they different sides of the same coin? In this paper, by considering the ways in which Sextus and Hume have examined these issues, I offer a Pyrrhonian response to Penelope Maddy's attempt to reject skepticism within the form of naturalism that she calls “second philosophy” (Maddy, 2007, 2017) and to Timothy Williamson's attempt to avoid skepticism from emerging within his knowledge-first approach (Williamson, 2000). Some lessons about Pyrrhonism result.     

先天视觉经验缺失对颜色认知的影响：一项ERP研究

感觉与认知是否是相互独立的？本研究通过对比先天盲被试与明眼被试在进行物体颜色判断时的行为反应和神经电生理信号变化,探讨视觉经验缺失对颜色认知的影响。结果发现,先天盲被试具有一定的颜色知识,但其水平低于明眼被试;两组被试都出现了由颜色不匹配所诱发的N400效应,且都表现出左半球优势;但是盲人组的N400效应大于明眼组,盲人组的N400反应潜伏期小于明眼组。该结果说明,直接的视觉经验是颜色认知的充分条件而非必要条件。     

Perceiving by proxy: Effect-based action control with unperceivable effects

Anticipations of future sensory events have the potential of priming motor actions that would typically cause these events. Such effect anticipations are generally assumed to rely on previous physical experiences of the contingency of own actions and their ensuing effects. Here we propose that merely imagined action effects may influence behaviour similarly as physically experienced action effects do. Three experiments in the response–effect compatibility paradigm show that the mere knowledge of action–effect contingencies is indeed sufficient to incorporate these effects into action control even if the effects are never experienced as causally linked to own actions. The experiments further highlight constraints for this mechanism which seems to be rather effortful and to depend on explicit intentions.     

Making sense of surveys and censuses: Issues in religious self-identification

Abstract

Censuses and surveys shape decisions, discourse and debates about people and their lived environments. The outcomes, in the case of a census, inform governments about resource distribution but also shape people's self-understanding about who they are and where they may be going. How people self-identify on censuses and surveys produces certain types of knowledge. This introduction emphasises the impact of those instruments on knowledge production and how numbers can be employed, often anecdotally, to further interests and claims. The way academics use and interpret such instruments has ethical and normative dimensions: numbers are not neutral but shape and are shaped by perceptions and identities. This introduction to a thematic issue of Religion introduces the contributing authors' diverse – historical, qualitative and quantitative – approaches that work together to produce their own kind of multi-disciplinary, academically located knowledge.
