人格特质研究的新进展

近二十年来,人格特质的研究取得了丰硕的成果,人格特质也已经成为心理学很多领域研究的课题。本文试图从人格的结构与描述、人格的行为遗传学研究、人格的发展、特质的进化等方面来探讨人格特质研究的新进展。     

FOK与情节记忆、语义记忆和内隐记忆关系的研究

实验采用R/K判断和PDP测量技术,研究了FOK判断与情节记忆、语义记忆和内隐记忆关系及其监测强度.实验结果表明FOK判断的准确性程度为R判断＞K判断,即对情节记忆监测的准确性要大于对语义记忆监测的准确性.FOK对于自动加工的预测准确性差异不显著,说明FOK监测对内隐记忆的作用是微弱的,由此推测无记忆是意识最高层面的活动.对记忆监测水平强度是由意识--无意识逐渐减弱的.FOK判断对意识性水平较高的记忆活动监测的准确性较强.     

自我和物体为参照系的心理旋转分离：内旋效应

采用虚拟的旋转不同角度左、右手模型,构建“左右手判断(Left and right hand judgment: LR)”任务和“相同－不同判断(same and different judgment: SD)”任务,考察这两种实验任务是否都存在内旋效应和角度效应,以此推论被试采用何种旋转策略。结果发现：（1） 两种实验任务结果均表现出显著的角度效应。（2）在LR任务条件下,存在显著的内旋效应,而在SD任务中不存在内旋效应。从而表明当人手图片作为心理旋转材料时,它具有双重角色。被试心理旋转加工时究竟选用何种参照系的旋转策略,与实验材料和实验任务两者都密不可分     

Psychophysical methods in study of consumers' perceived price change for food products

When adjusting product prices, marketers wish information concerning consumers' price perceptions. The present study aimed to develop an optimal pricing framework for food products by applying Weber's Law and Stevens' Power Law in psychophysics. The first phase attempted to measure the differential thresholds when magnitudes of prices were raised and lowered. The second phase was conducted to establish the psychophysical function representing perceived changes. Analysis showed consumers' differential thresholds were positively correlated with the initial price, consistent with Weber's Law. Further, participants' perceived change differed for increased and decreased prices. Products were perceived as cheaper only when medium-and low-priced products dropped dramatically in price. However, small reductions for the high-priced products were perceived as cheaper. Regardless of price changes, participants perceived products were more expensive when prices dropped by a small     

Modeling parenting stress trajectories among low-income young mothers across the child's second and third years: Factors accounting for stability and change.

This study investigated parenting stress trajectories among low-income young mothers and the factors that are associated with change and stability of parenting stress as children aged from 14 to 36 months old. With a sample of 580 young mothers who applied to the Early Head Start Program, growth mixture modeling identified 3 trajectory classes of parenting stress: a chronically high group (7% of the sample), an increasing group (10% of the sample), and a decreasing group (83% of the sample). Maternal personal resources distinguished between the increasing and decreasing classes, whereas maternal personal resources, child characteristics, and contextual influences explained differences between the chronically high and decreasing trajectory classes. Findings suggest that for interventions to be effective, programs need to assess maternal, child, and contextual factors to better address the particular unique needs of young mothers.     

Asymmetric discounting in intertemporal choice: a query-theory account

People are impatient and discount future rewards more when they are asked to delay consumption than when they are offered the chance to accelerate consumption. The three experiments reported here provide a process-level account for this asymmetry, with implications for designing decision environments that promote less impulsivity. In Experiment 1, a thought-listing procedure showed that people decompose discount valuation into two queries. Whether one considers delayed or accelerated receipt of a gift certificate influences the order in which memory is queried to support immediate versus delayed consumption, and the order of queries affects the relative number of patient versus impatient thoughts. Relative frequency and clustering of impatient thoughts predicts discounting and mediates the discounting asymmetry. Experiment 2 implicated query order causally: When participants listed reasons for immediate versus delayed consumption in the order used spontaneously in acceleration and delay decisions, the discounting asymmetry was replicated; reversing the order in which reasons were listed eliminated the asymmetry. The results of Experiment 3, which used an implicit-memory task, support a memory-interference account of the effect of query order.     

中国乡村社区集体行动的一个理论模型:以抗交村提留款的集体行动为例

本文以一类假想中的、很有可能曾经在中国乡村社区中发生过的抗交村提留款的集体行动为对象,以社会运动/集体行动这一研究领域内的现有理论成果为基础,提炼出了用于解释村民家庭户是否参与了抗交村提留款的集体行动这一因变量取值的一系列自变量组群,从而再现了社会运动/集体行动研究传统中的四大理论取向--古典理论、文化主义、结构主义和理性主义--的综合,对于中国经验案例的理论指导意义.     

瘢痕治疗的选择与思考

瘢痕作为人类最常见的疾病之一,其治疗一直是整形外科界研究的热点和焦点。本文从治疗方法的发展过程,认识到科学的认识论对方法论具有良好的指导作用,满意的治疗其根本在于提高医生的素质,从哲学角度对如何科学的选择治疗方法进行总结,指明从根本上解决瘢痕,最终要依靠现代发达的基础科学研究。     

语素意识在儿童汉语阅读中的作用

文章考察了语音意识、语素意识和命名速度在儿童汉语阅读中的作用。结果发现：语素意识和命名速度对汉字命名组词具有显著的预测作用;而语素意识和语音意识对同音字识别具有显著的预测作用。语素意识是唯一显著预测两种不同阅读任务的认知变量。对阅读障碍儿童所存在的缺陷进行分析,结果发现：76%的阅读障碍存在语素缺陷;相比之下,分别有43%和41%的阅读障碍存在语音缺陷和命名速度缺陷。结果表明汉语的语素意识在儿童阅读中具有重要作用,语素缺陷有可能成为儿童汉语阅读困难的主要原因。     

注意力缺损多动障碍与巴克利的行为反应抑制模型

长期以来,人们一直认为ADHD(注意力缺损多动障碍)的主要表现在于注意力过程的缺损,将焦点放在多动和注意过程上。20世纪90年代以来,人们对此症有了新发现。巴克利等人认为注意力后面的自控能力的低下和自我管理的缺陷才是本症的实质所在。该文从这一新的视角分析并阐明了该障碍的实质:行为执行机制的缺陷,并据此对该障碍的矫正提出了新看法。
