应用项目反应理论创建图形推理测验题库

自编235个图形推理测验题目。采用铆测验等值设计,以72个联合型瑞文测验题目为铆题,对初中到大学各能力层次的1733名男性进行了测验。使用BILOG MG3.0（边际极大似然估计）对实测数据进行了分析,采用Logsitic 3参数模型。剔除数据与模型拟合不好的题目以及信息函数最大值小于0.3的题目,最终建立一个包含181道题目的题库。该题库可以用于淘汰智力较低的应征青年     

返回抑制的容量研究：回顾与展望

返回抑制是指当注意返回到先前注意过的位置或客体时人们的反应变慢的一种抑制现象。自20世纪90年代中期以来,越来越多的返回抑制研究开始关注最多能在多少个线索化位置上观测到返回抑制效应,即返回抑制的容量问题。文章着重从序列线索化和同时线索化两方面介绍了当前返回抑制容量研究的主要成果,总结了该领域研究的特点及存在的问题,并对未来研究方向予以展望     

转换加工研究回顾

任务转换是人类认知活动的基本方式,其过程转换加工为中央执行系统的重要功能。转换加工在工作记忆中体现为控制竞争同一认知资源的两项任务之间相互转换的过程。执行转换任务的反应时比执行重复任务的反应时更长,两反应时之差为转换代价。行为实验和神经生理学实验在转换加工的研究范式、转换代价的成分以及执行控制的理论等领域取得一定成果,但也存在诸多争议。事件相关电位和功能磁共振成像技术的联合使用能直观地反映大脑转换加工的时、空动态变化特征,将为转换加工的进一步研究提供证据     

近代哲学向现代哲学转向的内在逻辑

德国古典哲学终结之后,哲学转向现代形态。“知识形而上学”是近代哲学转向现代哲学的逻辑主线。近代知识论企图为“知识”建立一个绝对可靠的基础,现代分析哲学、诠释学虽然否定了知识论的这种妄想,但他们仍企图通过语言和诠释为知识找寻一种深层的根据;存在主义、法兰克福学派和后现代主义则在知识异化形态下引发了对人的存在及其意义的追问,其实质是追问知识的价值问题。这一逻辑转换召示了哲学对科学知识更全面、更合理地把握和理解,召示了哲学向时代敞开。     

Output order in immediate serial recall

In two experiments, we examined the effect of output order in immediate serial recall (ISR). In Experiment 1, three groups of participants saw lists of eight words and wrote down the words in the rows corresponding to their serial positions in an eight-row response grid. One group was precued to respond in forward order, a second group was precued to respond in any order, and a third group was postcued for response order. There were significant effects of output order, but not of cue type. Relative to the forward output order, the free output order led to enhanced recency and diminished primacy, with superior performance for words output early in recall. These results were replicated in Experiment 2 using six-item lists, which further suggests that output order plays an important role in the primacy effect in ISR and that the recency items are most highly accessible at recall.     

Numerical reproduction in pigeons

Pigeons were trained to match the number of responses made during a production phase to the number of keylight flashes (2, 4, or 6) in a previous sample phase. In Experiment 1, there were 2 conditions in which the flashes were programmed to occur at a constant rate or within a constant overall duration. For both conditions, although accuracy was relatively low, responding increased linearly with flash number and coefficients of variation decreased. Positive transfer to novel numbers was obtained only when test and baseline trials had the same temporal organization, but multiple regressions revealed significant control by number independently of temporal cues. In Experiment 2, flashes were programmed to occur pseudorandomly to degrade the validity of temporal cues. Results were similar to in Experiment 1. A prototype response class model accounted for the major features of the data. According to the model, responses during the production phase are shaped into higher order units that are associated with different stimulus numbers and function as a rough category scale of numerosity.     

自我监控概念的重构

Snyder（1974）提出自我监控来解释自我呈现中的个体差异。他认为高自我监控者具有3个特征：关注行为的适宜性,对情境线索敏感,并以此作为行为调节的指南。作者通过文献回顾指出,Snyder对高自我监控的定义不妥。该文通过对自我呈现功能分析,指出自我呈现既有自我功能,又有人际功能。想要给他人留下期望的印象,自我呈现不仅要维系人际和谐,而且要维系自我和谐。根据这两个维度,该文对自我监控概念进行了重构。把自我监控者分为4种：高自我监控者在自我呈现过程中既维系自我和谐,又维系人际和谐;他人导向监控者只注重人际和谐;自我导向监控者只注重自我和谐;低自我监控者既不注意人际和谐,也不注意自我和谐     

高、低强迫症状个体的词语再认差异

比较了高强迫症状（High obsessive compulsive symptom, HOC）和低强迫症状（Low obsessive compulsive symptom, LOC）被试对于不同类型词语（强迫症敏感词、情绪词和中性词）再认成绩和记忆信心的差异。结果发现,HOC组记忆保存量显著低于LOC组（p<0.05）,表明HOC组对强迫症敏感词存在一定的偏好;通过对被试反应信心的检测和信号侦察论的应用,发现HOC组对中性词再认正误的判断觉察能力（d’值）低于LOC组（边缘显著：p＝0.054）;在正确反应信心上,被试类型和词语类型间存在交互作用,F(1,22)=4.60,p<0.05。本研究认为HOC组辨别能力的缺损可能导致其记忆信心方面的降低,这种假设还需要进一步的认知和脑功能研究来证实。     

交感神经系统在应激免疫调节中的作用

目前,越来越多的研究资料表明交感神经系统(SNS)参与了应激的免疫调节作用。有关研究主要集中在SNS与免疫系统间的解剖基础及相互作用、SNS参与应激的免疫调节作用的实验研究以及SNS与下丘脑-垂体-肾上腺轴（HPA）间的相互作用等几个方面。综合阐述这些研究结果,并着重分析SNS、应激与免疫系统间的相互作用及其机制
