概念及概念结构研究新进展

近来有关归类和概念结构的研究与理论出现了两个方面的转变。第一个方面是从概念定义属性的假设 (经典观 )到概念表征属性的观点 (概率观 ) ;第二个方面是从概念以相似性组织的观点到概念围绕理论而组织的观点。本文综合概述了基于相似性和理论驱动的归类理论。     

Using the Implicit Association Test does not rule out an impact of conscious propositional knowledge on evaluative conditioning

Implicit measures such as the Implicit Association Test (IAT) have recently become popular as tools in research on evaluative conditioning. The reason is that these measures are thought to be impervious to changes in valence that are due to conscious propositional knowledge about the relation between the conditioned stimulus (CS) and the unconditioned stimulus (US). I present data that raise doubts about the validity of this assumption. In two experiments, attitudes towards CSs as measured by the IAT were in line with instructed CS-US contingencies even though the CSs and USs were never actually paired. The results therefore suggest that IAT effects can be biassed by conscious propositional knowledge.     

Implicit and explicit prosocial motivation as antecedents of volunteering: The moderating role of parenthood

We test a model proposing that having children influences motivational pathways of volunteering in the same way across two different cultures. The model posits that parents’ engagement in volunteering is driven by implicit, whereas non-parents’ engagement in volunteering is related to explicit prosocial motivation. Participants were 570 parents and non-parents from Turkey and the US (M_age = 33.7 years; 58.2% female). Results across the two cultural contexts confirmed our model. Our findings highlight the need for considering implicit prosocial motivation as an antecedent of volunteering, and underline the importance of examining parenthood as a moderator for motivations to volunteer. Avenues for further research and implications for voluntary organizations are discussed.     

Judgments of remembering: the revelation effect in children and adults

When items on a recognition test are presented as a series of increasingly complete fragments rather than being presented initially in their fully intact form, adults' judgments of recognition exhibit an increased tendency to judge items as "old," an illusion of recognition referred to as the revelation effect. The present study used pictorial stimuli to test for a revelation effect with 4-year-olds, 8-year-olds, and adults (N = 76). A reliable revelation effect was found at all ages tested, indicating that the complex fluency-of-processing discrepancy detection and attribution mechanisms thought to be responsible for the effect function similarly across an age range from 4-years-of-age through adulthood. It was also found that the recognition decisions of the 8-year-olds and the adults were affected by how quickly they were able to identify a picture during the revelation phase of the recognition test. This effect was not found with the 4-year-olds, suggesting an age difference in the awareness and strategic use of an implicit memory effect when making explicit judgments of recognition.     

内隐自尊的稳定性--成败操纵对内隐自尊的影响

本研究以瑞文智力测验为成败操纵基本任务,对成败操纵前后、接受成功反馈和失败反馈的个体在内隐联想测验中的反应及其内隐自尊情况进行了分析研究,结果表明：(1)不论是接受成功反馈还是失败反馈,成败操纵后,被试的反应速度都显著地快于操纵前;(2)不论是接受成功反馈还是失败反馈,成败操纵后,被试的内隐自尊水平都显著地低于操纵前。内隐自尊易受即时的关于自我的情绪体验的影响,具有不稳定性,当个体兴奋水平、情绪唤醒水平较高,动机较为强烈时,内隐自尊作用将受到抑制。     

现代世界观中的意识及其哲学难题

人是具身心智的存在者,其存在方式独特性在于:他既依赖于物理形态的身体,又有存在论上不可还原性的主观性。因此如何在现代世界观中一致且完备地解释和理解人遂成了心智哲学的大问题。如果坚持现代世界观的基本立场一致性,那么对意识的解释和理解不可避免存在着"难问题"所界定的不完备性。人们大致从三个进路来处理不完备性的局面。然而,原则上它们都无法实现一致且完备的要求,因为这里存在一个根本的局限,即不可能通过认识论的方法在两种存在论形式(无和有)之间实现等价转换。尽管在认识论上这是一个悲观的结局,但另一方面它又是积极的,因为它显示了个体经验在存在论上是独一无二的。     

Drinking without thinking: an implicit measure of alcohol motivation predicts failure to control alcohol use

Addiction is characterized by dyscontrol - substance use despite intentions to restrain. Using a sample of at-risk drinkers, the present study examined whether an implicit measure of alcohol motivation (the Implicit Association Test [IAT]; Greenwald, A.G., McGhee, D.E., & Schwartz, J.L.K. (1998). Measuring individual differences in implicit cognition: the Implicit Association Test. Journal of Personality and Social Psychology, 74, 1464-1480) would predict dyscontrol of alcohol use. Participants completed an IAT and, to elicit motivation to restrain alcohol use, were instructed that greater consumption in a taste test would impair performance on a later task for which they could win a prize. All participants viewed aversive slides and then completed a thought-listing task. Participants either exerted self-control by suppressing negative affect and thoughts regarding the slides or did not exert self-control. Post-manipulation, the groups did not differ in mood, urge to drink or motivation to restrain consumption. During the subsequent taste test, participants whose self-control resources were depleted consumed more alcohol than did those in the control group. Additionally, the IAT, but not an explicit measure of alcohol motivation, more strongly predicted alcohol use when self-control resources were depleted. The results indicate that the IAT may have utility in predicting dyscontrolled alcohol use.     

Remembering versus knowing during face recognition in unilateral temporal lobe epilepsy patients with or without hippocampal sclerosis

Recognition memory involves knowing an item was learned (familiarity) and remembering contextual details about the prior learning episode (recollection). We tested three competing hypotheses about the role of the hippocampus in recollection and familiarity. It mediates either recollection or familiarity, or serves both processes. We further tested whether the left temporal lobe mediates recollection and the right temporal lobe familiarity (modes of processing view), or whether the two temporal lobes mediate remembering material specifically (material specificity view). We investigated 24-h face recognition using the "remember-know" procedure. We studied 23 left and 24 right temporal lobe epilepsy (LTLE/RTLE) patients with and without hippocampal sclerosis (HS+/HS-) and 31 healthy participants. HS+ patients made fewer know responses than HS- patients or healthy participants. RTLE was related to fewer remember responses than LTLE. Our results suggest the hippocampus has a critical role in familiarity. Further, our findings support the material specificity hypothesis of laterality.     

Understanding the Subjective Point of View: Methodological Implications of the Schutz-Parsons Debate

The bone of contention that divides Alfred Schutz and Talcott Parsons in their 1940–1941 debate is that Schutz acknowledges an ontological break between the commonsense and scientific worlds whereas Parsons only considers it “a matter of refinement.” Schutz’s ontological distancing that disconnects the “world of consociates” where social reality is directly experienced in face-to-face contacts, and the “world of contemporaries” where the Other is experienced in terms of “types” has been crucial to social scientists. Implicated in the break is that all intellectual attempts to understand experiences of Others must be based on the “models” constructed in the “world of contemporaries” (or “predecessors”); hence, epistemologically, to grasp the subjective point of view with a here-and-now understanding is an outright impossibility. Based on a Schutzian perspective, the author suggests that the sociologist must objectivize the Thou-orientations involved in his/her analysis in order that s/he can possibility grasp the subjective point of view in objective terms.
