Shaping of rule-governed behaviour

Over an experimental session of 80 trials, subjects counted brief auditory stimuli ("clicks") in stimulus presentation periods and indicated the number counted by pressing a key the corresponding number of times in subsequent response periods. "Correct" answers resulted in feedback. Unknown to the subjects, the feedback criterion was based on speed of pressing rather than on the correct number of presses. Speed of pressing was modified by response consequences when feedback was made dependent on pressing faster or slower than baseline speed. Modification of speed occurred independently of rules and without the subjects' ability to describe contingency or response requirements. The results suggest that non-verbal contingencies may have a shaping effect on non-salient and non-described attributes of rule-governed behaviour, and it is argued that this may be an important control mechanism of low-level behavioural attributes that are unlikely to be guided by verbal discriminative stimuli.     

Knowledge,probability, and credibility

This paper concerns study of the credibility of human sources of evidence and its relation to the inferential value of testimony they provide. From a certain view of 'knowledge' in epistemology comes the suggestion that credibility assessment can be construed as a cascaded inference in which attributes of human source credibility are identified. Scholarship from evidence law in jurisprudence suggests an evidential basis for credibility assessment in terms of these attributes. Applying Bayes' rule to this cascaded inference offers a way of expressing and combining credibility-related beliefs in the process of assessing the inferential value of evidence.     

THE EXISTENCE OF GOD AND THE CREATION OF THE UNIVERSE

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.     

雇主品牌结构与求职倾向关系

利用重新修订非特指行业的雇主品牌量表,以求职倾向为因变量,通过两个有递进关系的研究,证实不仅雇主品牌结构的功能特征正向影响求职倾向,雇主品牌结构的象征特征与求职者追求的理想自我形象一致性也正向影响求职倾向,表明人们求职时既注重满足个人物质利益的雇主品牌功能特征,也关注求职企业雇主的特征风格与自我理想形象的契合。     

意识是情景记忆加工的必要条件？

在情景记忆的发展历程中,Tulving逐渐地将其与意识相联系。但是,无论来自正常被试的情景记忆中静态的视觉、语词和动态的视觉—动作加工特性方面的研究,还是来自遗忘症患者、婴儿以及动物等方面的情景记忆研究,均表明情景记忆具有无意识特性,这些均与Tulving对情景记忆的界定相矛盾。而情景记忆在人类进化过程中所表现出的自然属性和社会属性,则合理的解释了情景记忆所具有的无意识和意识属性。因此,只有结合情景记忆在人类发展历程所表现出的双重属性,才能宏观、全面地把握情景记忆的整体概貌。     

动态情景中颜色特征和身份特征在返回抑制中的作用

在动态的“线索-靶子”范式中引入隧道刺激, 以靶子与线索的非空间特征相同时的反应延迟测量返回抑制效应。实验1利用单向隧道创设客体的空间位置信息明确且可靠的条件, 考察客体的颜色特征在返回抑制中的作用。实验2利用双向隧道创设客体的空间位置信息不明确的条件, 考察客体的颜色特征在返回抑制中的独立作用。实验3、4分别采用与实验1、2类似的方法, 在动态任务情景中考察客体的身份特征在返回抑制中的作用。结果显示, 线索呈现与靶子呈现的时间间隔较长时, 4个实验中均存在显著的返回抑制效应。这表明, 动态情景中, 客体的空间位置信息明确且可靠时, 颜色特征和身份特征在返回抑制中都发挥着重要作用; 客体的空间位置信息不明确时, 颜色特征和身份特征在返回抑制中也都具有相对独立的作用。     

Stimuli previously associated with reinforcement mitigate resurgence

Resurgence refers to the recurrence of an extinguished target behavior following subsequent suspension of alternative reinforcement. Delivery of reinforcers during extinction of alternative behavior has been shown to mitigate resurgence. The present experiment aimed to determine whether delivering stimuli associated with reinforcers during resurgence testing similarly mitigates resurgence. Three groups of rats pressed target levers for food according to variable‐interval 15‐s schedules during Phase 1. In Phase 2, lever pressing was extinguished, and an alternative nose‐poke response produced alternative reinforcement according to a variable‐interval 15‐s schedule. Food reinforcement was always associated with illumination of the food aperture and an audible click from the pellet dispenser during Phases 1 and 2. Phase 3 treatments differed between groups. For one group, nose poking continued to produce food and food‐correlated stimuli. Both of these consequences were suspended for a second group. Finally, nose poking produced food‐correlated stimuli but not food for a third group. Target‐lever pressing resurged in the group that received no consequences and in the group that received only food‐correlated stimuli for nose poking. Resurgence, however, was smaller for the group that received food‐correlated stimuli than for the group that received no consequences for nose poking. Target‐lever pressing did not increase between phases in the group that continued to receive food and associated stimuli. Thus, delivery of stimuli associated with food reinforcement after suspension of food reduced but did not eliminate resurgence of extinguished lever pressing. These findings contribute to potential methodologies for preventing relapse of extinguished problem behavior in clinical settings.     

我所了解的英国医学伦理学教育

英国的医学伦理学教学强调病人的主体化和“去客体化”．关注病人权利,尤其是弱势群体的权益。融入法律等其他学科的内容,注重跨学科的教学与交流。这样一种教学理念是符合医学伦理学的人文属性。值得我们借鉴。     

Attracting Applicants in the War for Talent: Differences in Work Preferences Among High Achievers

This study examines how several indicators of ability and achievement are associated with individual differences in preferences for job and organizational attributes. Results from a sample of 378 business and liberal arts students suggest that students with high cognitive ability and all types of high achievement place greater importance on interesting and challenging work than do other students. However, on other work attributes (e.g., job flexibility, pay practices, fast-track promotion systems), students with high cognitive ability and high academic achievement (i.e., grade point average) appear to have different preference patterns from those with high social achievement (e.g., extracurricular and leadership activities). Results are discussed in terms of implications for employers and future research.     

Biodata Validity Decay and Score Inflation with Faking: Do Item Attributes Explain Variance Across Items?

Rating scales were developed to assess the biodata dimensions offered by Mael (1991). Biodata items assessing conscientiousness were administered under honest-responding and faking-good conditions. Item attributes were examined to determine their value in predicting item validity for honest respondents and item validity for faking respondents. Analyses were also conducted to determine whether the degree of item faking was related to item attributes. Item attributes associated with item validity for honest respondents are not the same as the item attributes indicative of item validity for the faking respondents. We suggest that this makes it very difficult to develop a biodata questionnaire which will be equally valid for both honest and faking respondents.
