Hume's Epistemology: The State of the Question

This article surveys the state of the literature on Hume’s epistemology, focusing on treatments of what has come to be known as the “Kemp Smith problem,” that is, the problem of reconciling Hume’s skepticism with his naturalism. It first surveys the literature on this issue with regard to the Treatise, moving on to briefly compare the Treatise and the Enquiry in virtue of their epistemological frameworks, before finally examining the literature with regard to the first Enquiry.     

欺骗判断与欺骗行为中自我控制的影响

欺骗判断与欺骗行为有着不同的心理机制, 正确认识二者之间的关系有助于增强人际间的信任和团队的长远利益。采用行为学实验从两种视角下考察自我控制对欺骗的影响。实验1采用材料评定的方法考察了识别他人自我控制能力状况对欺骗判断的影响, 结果发现对比高自我控制能力的人, 被试更倾向于认为低自我控制能力的人更有可能为了自己的利益产生欺骗行为和欺骗倾向。实验2采用颜色Stroop任务考察了识别他人自我控制资源衰竭状况对欺骗判断的影响, 结果发现当识别他人自我控制资源衰竭时, 在评价他人为自己利益去欺骗、为他人利益去欺骗以及在特定情境中欺骗倾向上, 没有发现任何显著的主效应或交互作用。实验3采用视觉−感知任务来考察不同水平的自我控制能力对欺骗行为的影响, 结果发现, 对比高自我控制组, 低自我控制组有更多的欺骗行为和欺骗倾向。实验4采用颜色Stroop任务和视觉−感知任务来考察自我控制资源对欺骗行为的影响, 结果发现, 对比控制组, 自我控制资源衰竭组有更多的欺骗行为和欺骗倾向。这些研究结果表明, 在进行欺骗判断时, 相比自我控制资源状况, 个体会优先识别他人的自我控制能力水平来判断其是否具有欺骗动机或欺骗倾向。在欺骗行为中, 高自我控制能力的个体, 能够更好地抑制自私动机, 更多的考虑长远利益, 出于自身利益去欺骗的可能性会更小; 自我控制资源充足的个体, 更有可能会经得住诱惑, 自私自利的欺骗行为发生的可能性也会更小。     

人造物概念的表征：功能、意图和目的论的解释

以概念结构研究从“相似”到“解释”的理论转向为背景,评述人造物领域的“意图-历史论”（Bloom, 1996）,提出人造物概念结构中自上而下的约束是来自“使用目的”而不是“设计意图”。分析近期报告的大量实验,最后提出人造物概念表征的“基于使用的目的论”的解释模式和人造物归类的双重目标模型。     

中国领导干部人格类型研究

该文用MBTI中文修订版对中国东部、中部、西部共745名领导干部进行测试,得出了我国领导干部人格类型的总体分布情况,以及不同性别、不同年龄、职务级别、单位性质、工作属地、学历的领导干部在16种人格类型上的分类：我国领导干部人格类型以ESFJ(外向感觉情感判断)类型居多,其次为ESFJ(外向感觉思维判断)类型,并且更多地偏向“S”(感觉)、“F”(情感)和“J”(判断)。     

用不同外部表征方式集中呈现信息条件下的因果力判断

在分别用文字陈述、表格和图形三种外部表征方式集中呈现因果信息的条件下,用直接估计因果力大小的实验范式考察单一因果关系因果力估计的特点,检验概率对比模型,效力PC理论和pCI规则。让287名大学生被试估计不同化学药物影响动物基因变异的能力。结果发现,对单一因果关系因果力估计具有以下4个特点：⑴不对称性：在预防原因条件下的因果力估计较多符合效力PC理论,而在产生原因条件下的因果力估计一般符合概率对比模型;⑵文字陈述、表格和图形三种信息外部表征方式,不影响产生原因条件下的因果力估计,但影响预防原因条件下的因果力估计。在预防原因条件下,与文字陈述和表格表征相比,图形表征会促使更多被试按效力PC理论来做因果力估计;⑶没有被试使用pCI规则;⑷被试估计因果力所使用的规则存在明显的个体差异。     

The influence of expertise and of physical complexity on visual short-term memory consolidation

We investigated whether the expertise of a perceiver and the physical complexity of a stimulus influence consolidation of visual short-term memory (VSTM) in a S1-S2 (Stimulus 1-Stimulus 2) change detection task. Consolidation is assumed to make transient perceptual representations in VSTM more durable, and it is investigated by postexposure of a mask shortly after offset of the perceived stimulus (S1; 17 to 483?ms). We presented colours, Chinese characters, pseudocharacters, and novel symbols to novices (Germans) or experts of Chinese language (Chinese readers). Physical complexity was manipulated by the number of strokes. Unfamiliar material was remembered worse than familiar material (Experiments 1, 2, and 3). For novices the absolute VSTM performance was better for physically simple than for complex material, whereas for experts the complexity did not matter-Chinese readers memorized Chinese characters (Experiment 3). Articulatory suppression did not change these effects (Experiment 2). We always observed a strong effect of SOA, but this effect was influenced neither by physical complexity nor by expertise; only the length of the interstimulus interval between S1 and the mask was relevant. This was observed even with short stimulus onset asynchrony (SOA) of 100?ms (Experiment 2) and in comparing colours and characters (Experiment 5). However, masks impaired memory if they were presented at the locations of the to-be-memorized items, but not beside them-that is, interference was location-based (Experiment 6). We explain the effect of SOA by the assumption that it takes time to stop encoding of information presented at item locations with the offset of S1. The increasing resistance against interference by irrelevant material appears as consolidation of S1.     

Should We Treat Depression with drugs or psychological interventions? A Reply to Ioannidis

We reply to the Ioannidis's paper "Effectiveness of antidepressants; an evidence based myth constructed from a thousand controlled trials." We disagree that antidepressants have no greater efficacy than placebo. We present the efficacy from hundreds of trials in terms of the percentage of patients with a substantial clinical response (a 50% improvement or more symptomatic reduction). This meta-analysis finds that 42-70% of depressed patients improve with drug and 21%-39% improve with placebo. The response benefit of antidepressant treatment is 33%-11% greater than placebo. Ioannidis argues that it would be vanishingly smaller because systematic biasing in these clinical trials would reduce the drug-placebo difference to zero. Ioannidis' argument that antidepressants have no benefit is eroded by his failures of logic because he does not present any evidence that there are a large number of studies where placebo is substantially more effective than drug. (To reduce to zero, one would also have to show that some of the unpublished studies find placebo better than drug and have substantial systematic or methodological bias). We also present the empirical evidence showing that these methodological concerns generally have the opposite effect of what Ioannidis argues, supporting our contention that the measured efficacy of antidepressants likely underestimates true efficacy. Our most important criticism is Ioannidis’ basic underlying argument about antidepressants that if the existing evidence is imperfect and methods can be criticized, then this proves that antidepressant are not efficacious. He presents no credible evidence that antidepressants have zero effect size. Valid arguments can point out difficulties with the data but do not prove that a given drug had no efficacy. Indeed better evidence might prove it was more efficacious that originally found. We find no empirical or ethical reason why psychiatrists should not try to help depressed patients with drugs and/or with psychotherapeutic/behavioral treatments given evidence of efficacy even though our treatment knowledge has limitations. The immense suffering of patients with major depression leads to ethical, moral, professional and legal obligations to treat patients with the best available tools at our disposal, while diligently and actively monitoring for adverse effects and actively revising treatment components as necessary.     

The role of form and meaning in the processing of written morphology: A priming study in French developing readers

Three visual priming experiments using three different prime durations (60 ms in Experiment 1, 250 ms in Experiment 2, and 800 ms in Experiment 3) were conducted to examine which properties of morphemes (form and/or meaning) drive developing readers’ processing of written morphology. French third, fifth, and seventh graders and adults (the latter as a control group) performed lexical decision tasks in which targets were preceded by morphological (e.g., tablette–TABLE, “little table–table”), pseudoderived (e.g., baguette–BAGUE, “little stick–ring”), orthographic control (e.g., abricot–ABRI, “apricot–shelter”), and semantic control (e.g., Tulipe–FLEUR, “tulip–flower”) primes. Across all groups, different patterns of priming were observed in both morphological and orthographic/semantic control conditions, suggesting that they all process morphemes as units when reading. In developing readers, the processing of written morphology is triggered by the form properties of morphemes, and their semantic properties are activated later in the time course of word recognition. In adults, patterns of priming were similar except that the activation of the form properties of morphemes decreased earlier in the time course of word recognition. Taken together, these findings indicate that French developing readers process both the form and meaning properties of morphemes when reading and support a progressive quantitative change in the development of morphological processing over the course of reading development.     

Spatial Stroop and spatial orienting: the role of onset versus offset cues

The present study investigated whether offset cues have the same attentional consequences in the spatial Stroop effect as onset cues. Experiments 1 and 2 compared the attentional effects of onset–offset cues versus offset cues on the spatial Stroop effect, whereas Experiment 3 compared the attentional effects of onset versus offset cues. Across these experiments, independent of cue type (onset–offset or onset vs. offset) and even at long stimulus-onset asynchrony, attentional cueing did not revert into inhibition of return and was modulated by spatial Stroop with greater cueing effects for incongruent arrow’s direction and position. In addition, onset–offset or onset and offset cues produced comparable cueing effects in the location-direction congruent condition, and onset–offset or onset cues produced greater facilitation than offset cues in the incongruent condition. From a different perspective, peripheral cueing modulated the spatial Stroop effect in the same direction for onset–offset or onset and offset cues, although the reduction in spatial Stroop at cued locations was smaller with offset than with onset–offset or onset cues.
