Rhetoric,reasonableness and ethics: An essay on Perelman

The article deals with an interpretation of the work of Ch. Perelman. The author tries to determine the meaning of reasonableness in a hermeneutical and anthropological perspective. He then places the work of Perelman in the light of the theory of symbolic interactionism of G.H. Mead.     

短时距估计中的标量特性

使用单任务研究程序,采用预期式研究范式和再现时距的研究方法,从心理物理学的视角,通过三个实验系统地考查了人类短时距估计的标量特性、变异源、时距估计中的转换点和韦伯函数的形态等问题。结果表明,刺激物的运动、变化、速度和物理时距是被试进行短时距估计的重要变异源;被试在实验中表现出高估较短时距和低估较长时距的倾向,时距估计的转换点为11.1s;计时过程中得到的韦伯函数是个分段连续函数, 韦伯函数的拐点有两个12s和21s,这两点与本研究得到的时距估计转换点具有部分一致性     

从伦理的视角看“三个代表”

“三个代表”重要思想,从伦理学上进行分析,饱含着深刻的伦理智慧,浸润着美善和正义的光华,它既可以理解为一种全新的政治伦理,又可以指谓一种进步的社会伦理,还可以从经济伦理、科技伦理和文化伦理等角度加以阐释与论证。因此,我们有理由认为,“三个代表”的伦理精神和伦理目标将构成当代中国社会的主流伦理,成为指导我国当前公民道德建设的伟大旗帜和促成中华伦理文化伟大复兴的理论指南。     

高强迫症状个体对图片刺激的注意偏向

以往强迫症注意偏向研究呈现出不一致的结果。为探索研究结果的不一致性是否由于被试取样和刺激选择所导致,当前研究改用非临床强迫症状个体作为研究对象,采用图片作为刺激来引发被试的反应和脑电波的变化。研究采用2(高强迫症状组、低强迫症状组)×3(中性图片、一般威胁图片和强迫相关图片)的混合实验设计,因变量为反应时和相关的脑电成分,结果显示:高强迫症状组较低强迫症状组对强迫相关图片表现出了更大幅度的P2波幅的变化。从而可以推断出,高强迫症状个体对强迫相关图片表现出了明显的注意偏向,其成分为注意脱困,主要发生在早期自动化加工阶段。     

Danger and usefulness are detected early in auditory lexical processing: evidence from electroencephalography

Visual emotionally charged stimuli have been shown to elicit early electrophysiological responses (e.g., [Ihssen et al., 2007], [Schupp et al., 2003] and [Stolarova et al., 2006]). We presented isolated words to listeners, and observed, using generalized additive modeling, oscillations in the upper part of the delta range, the theta range (Bastiaansen & Hagoort, 2003), and the lower part of the alpha range related to degree of (rated) danger and usefulness (Wurm, 2007) starting around 150 ms and continuing to 350 ms post stimulus onset. A negative deflection in the oscillations tied to danger around 250-300 ms fits well with a similar negativity observed in the same time interval for visual emotion processing. Frequency and competitor effects emerged or reached maximal amplitude later, around or following the uniqueness point. The early effect of danger, long before the words’ uniqueness points, is interpreted as evidence for the dual pathway theory of LeDoux (1996).     

The Bottoming‐Out Experience and the Turning Point: A Phenomenology of the Cognitive Shift From Drinker to Nondrinker

The bottoming‐out experience (BOE) is commonly considered the catalyst to sobriety. A phenomenological study was conducted to gain an understanding about this occurrence for alcoholics. Results indicated two distinct experiences: the BOE and the turning point.     

Validating the Beck Depression Inventory-II in Indonesia's general population and coronary heart disease patients

This study assesses the validity and determines the cut-off point for the Beck Depression Inventory-II (the BDI-II) among Indonesians. The Indonesian version of the BDI-II (the Indo BDI-II) was administered to 720 healthy individuals from the general population, 215 Coronary Heart Disease (CHD) patients, and 102 depressed patients. Confirmatory factor analysis indicated factorial similarity across the three samples. Significant correlations between the Indo BDI-II and other self-report measures related to depression demonstrated construct validity of the Indo BDI-II. Furthermore, there was a highly significant difference in the Indo BDI-II scores between depressed patients and non-depressed participants. Internal consistency and re-test reliability of the Indo BDI-II were acceptable. The receiver operating characteristic (ROC) curve indicated that the cut-off point of the Indo BDI-II for a mild severity of depression in Indonesian population should be 17. We conclude that the Indo BDI-II is a valid measure of depression, both in the Indonesian general population and in CHD patients.     

Perceptual and response components in repetition priming of spoken words and pseudowords

Two experiments explored repetition priming effects for spoken words and pseudowords in order to investigate abstractionist and episodic accounts of spoken word recognition and repetition priming. In Experiment 1, lexical decisions were made on spoken words and pseudowords with half of the items presented twice (～12 intervening items). Half of all repetitions were spoken in a “different voice” from the first presentations. Experiment 2 used the same procedure but with stimuli embedded in noise to slow responses. Results showed greater priming for words than for pseudowords and no effect of voice change in both normal and effortful processing conditions. Additional analyses showed that for slower participants, priming is more equivalent for words and pseudowords, suggesting episodic stimulus–response associations that suppress familiarity-based mechanisms that ordinarily enhance word priming. By relating behavioural priming to the time-course of pseudoword identification we showed that under normal listening conditions (Experiment 1) priming reflects facilitation of both perceptual and decision components, whereas in effortful listening conditions (Experiment 2) priming effects primarily reflect enhanced decision/response generation processes. Both stimulus–response associations and enhanced processing of sensory input seem to be voice independent, providing novel evidence concerning the degree of perceptual abstraction in the recognition of spoken words and pseudowords.     

Locating Potential Leverage Points In A Systems Thinking Causal Loop Diagram Toward Policy Intervention

Outcomes depending on various interacting and adaptive parts and actors in a volatile, uncertain, complex, and ambiguous (VUCA) world are challenging to analyze using traditional thinking. Hence, Systems Thinking (ST) can be applied as a tool to aid policy makers in designing interventions that anticipates various ways in which a system might react to policy changes through the practice of integrating multiple perspectives into a causal loop diagram (CLD). We formalize criteria for identifying potential leverage points (PLP) in a CLD. Identifying PLPs enable policy makers to apply ST tools to devise strategies that are capable of addressing VUCA problems.     

On the prediction of academic performance with personality traits: A replication study

We describe a large sample study (N = 652) that had two purposes. The first was to replicate a previous study (Paunonen & Ashton, 2001a, Journal of Research in Personality) in which we showed that lower-level personality trait measures related to achievement motivation predict the academic success of university students. The second purpose was to test our earlier conclusion that such lower-level traits are frequently superior to broader personality factors for accuracy in prediction. Both purposes were met in this study, providing more evidence for our general claim that aggregating narrow personality trait measures into broad factor measures can sometimes have negative consequences regarding the prediction and understanding of important outcomes, including academic performance.
