The purposes of the present study were (a) to examine the validity of selected employment tests potentially useful in selecting production workers engaged in the construction of boxboard containers and (b) to evaluate the applicability of the tests to minority and non-minority workers. Using data collected from 100 production workers employed by the same company but located in two different geographical regions, it was found that a short test battery was potentially useful in selecting production employees without necessarily introducing unfair racial bias. Implications of the results for future research studies and test validation efforts involving differential and single-group validity are discussed.  相似文献

Few nonverbal developmentally disabled children ever receive adequate vision assessment because of their limited language skills. The present study details a simultaneous discrimination procedure for measuring subjective visual acuity in such children. A stimulus fading procedure was used to train a discrimination between Snellen Es differing in orientation, and a psychophysical tracking method was used to determine acuity thresholds. The procedure was tested with 11 nonverbal autistic and schizophrenic children and validated with four nonpsychotic children. Eight of the psychotic children were successfully examined in one to three sessions. Two of these children were identified as having significant acuity losses. The validity assessment showed that the experimental procedure resulted in thresholds equal to or slightly lower than those obtained with the Illiterate E chart.  相似文献

Sixty faculty and staff women at a mid–sized university were surveyed to determine the extent to which they perceived sex discrimination. Faculty women perceived sex discrimination more than did staff women and were less likely to believe that academia was a meritocracy. Differences in perception of sex discrimination were also found based upon the gender composition of the departments. Women in departments that were male–dominated were less likely to perceive sex discrimination and more accepting of the meritocracy notion than were women in departments that were not male–dominated.  相似文献

Pigeons were trained to discriminate the duration of a stimulus. One response in a psychophysical choice situation was reinforced, given the immediately prior presentation of a stimulus duration in one class of durations called short durations, and the other response was reinforced given the immediately prior presentation of a stimulus duration in a second class called long durations. Durations of equal logarithmic difference from the cutoff, whether in the short or long class, yielded equal accuracy. Accuracy was a function not only of the properties of the stimuli to be discriminated, but also of the experimental contingencies used. Accuracy was greater in variable-ratio than in fixed-ratio schedules of reinforcement of the discriminative responses, and was lower at the beginning than later in individual fixed ratios. Proportion of short or long responses (response bias) was affected by sequential dependencies among long and short durations and was effectively controlled through the use of asymmetric reinforcement and fixed-ratio contingencies.  相似文献

两只恒河猴在实验条件下以正多边形和不规则多边形的边数为刺激实体进行数量辨别训练,以最后测得恒河猴对多边形边(角)数识别的极限。实验结果表明,恒河猴在多边形边数相差为1的条件下,其辨别上限为7:8。这与以前以白色卡片上黑色圆点为刺激实体所得到的实验结果是一致的。  相似文献

A procedure was developed to enable nonverbal organisms to report what they remember of the temporal organization of their recent behavior. A baseline behavior with known temporal structure was established by a concurrent variable-interval variable-interval schedule for two temporal patterns of behavior (two different classes of reinforced interresponse times). The five pigeon subjects emitted these two temporal patterns on a center key and were occasionally given a short-term memory probe for their most-recently-emitted pattern. The probes consisted of symbolic delayed matching-to-sample tests, in which a response on a green side key was reinforced if the most recent pattern belonged to the shorter reinforced class, and a response to a red side key was reinforced if the most recent pattern belonged to the longer reinforced class. All subjects could report with over ninety percent accuracy what their most recently emitted behavioral pattern was when a retention interval separating the pattern from the memory probe was only .1 seconds. The retention interval was then manipulated, and it was found that recall for a pattern was frequently above chance after a delay of as much as eight seconds. Thus, pigeons can remember their most recent interresponse time not only right after it is emitted, but for several seconds thereafter. In other conditions, the patterns themselves were manipulated. It was found that as the patterns became more similar, discrimination became poorer. These results agree with the view that reinforcement tends to organize and integrate the local structure of behavior to the extent to which that structure is remembered.  相似文献

论三段论推理过程中结论正确性的两种判断标准   总被引:4,自引:1,他引:3  
人们进行三段论推理加工时是根据什么标准来判定推理结论的正确性的?实验结果支持下述观点:人们在进行三段论推理过程中,在判定推理结论的正误时,存在两种判定标准:一种是“形式标准”,另一种是“内容标准”;两种判定标准对于人们判定结论的正确性都有影响,哪个判定标准的影响力更大依赖于人们已掌握的知识结构。  相似文献

In his Proslogion, Anselm presents a proof for God's existence which has attracted a tremendous amount of scholarly attention. In spite of all that has been said about this proof and proofs for God's existence more generally, scholarly consensus seems to dissipate when it comes to determining whether theistic proofs are persuasive and sound. In this article, I will argue that there is a way to provide compelling proof for the existence of God. To substantiate this claim, I will not attempt to prove that God exists apart from His revelation in any of the ways that have been advocated by various philosophers of religion. Rather, I will endeavor to explain that Anselm's approach to offering evidence for God's existence is quite different from the approach that modern philosophers tend to attribute to him and to elaborate on what that approach involves by reading Anselm's argument in the context of Augustine's De Trinitate and the whole of the Proslogion.  相似文献

该项工作研究了21名女大学生和研究生鉴别两个陌生人的噪声时,六个脑区的事件相关电位(ERPs)。结果表明,双音节语义嗓声的鉴别更易引起明显的ERPs变化;两个陌生人嗓声不等概率呈现,较等概率呈现更易引起明显的ERPs变化。在单音节嗓声鉴别中,在左额区引起N200波波幅增高;而在右颞区引起P300波潜伏期的增长。在双音节语义嗓声鉴别中,除右顶叶外在其它五个脑区引起P300波波幅增高,在右额区引起P300波潜伏期明显缩短。  相似文献

Abstract. Kant argues that any argument for a transcendent God presupposes the logically flawed ontological argument. The teleological argument cannot satisfy the demands of reason for a complete explanation of the meaning and purpose of our universe without support from the cosmological argument. I avoid the assumption of a perfect being, and hence the ontological argument, in my version of the cosmological argument. The necessary being can be identified with the creator of the universe by adding analogical mental relations. The creation of the universe is then shown to reflect modern scientific cosmology as well as stories and metaphors in the Eastern and Western religious traditions and to resolve the problem of evil.  相似文献

笔者认为,“论三段论推理过程中结论正确性的两种判断标准”[1]在其说明的实验及相关论述中,至少有以下问题值得探讨与商榷。1课题中的概念与构思1.1三段论第一格AAA式≠三段论本章标题讲的是作为人类思维活动重要形式的“三段论”,实验研究中使用的材料全是三段论第一格AAA式。1.2人(或人们)≠大学生文章摘要部分的主称为“人们”,实验小结部分的二条结论,第一条主称“大学生”第二条主称“推理者”。1.3实际推理≠对推理的分析≠判定推理结论正误实际的推理与对推理的分析和“判定推理结论是否正确”在概念及操…  相似文献
