咳嗽与咳嗽治疗

咳嗽是临床上常见的症状之一,其对人们健康的影响是辩证的,咳嗽治疗也是辩证的。有需要止咳的,有需要治疗但不是止咳治疗的,有不需要治疗的,还有要鼓励患者咳嗽的。临床上遇到咳嗽患者时,要用辩证的观点进行治疗,辨证施治,用哲学观来看待问题,最终才能解决问题。     

概念和类别研究中基于解释的观点

该文介绍了概念和类别研究中基于解释的观点。和原型观、样例观不同,基于解释的观点强调了三个方面的影响因素,一是知识背景的影响;二是不同的学习任务的影响;三是类别知识的运用的再影响。该文从时问的先后描述了解释观的主要观点及其典型的实验研究。     

大学生健全人格特征的内隐观研究

本研究在对100名大学生进行预调查的基础上,按照各项特征频数出现高低,选择频数出现最高的30个人格特征编制成大学生健全人格的内隐观调查问卷。以重庆市8所高校398名学生为调查对象,要求他们对各项健全人格的特征按照重要性进行评分。结果显示：大学生认为人格健全的学生应具备道德品质、学习和工作态度、良好的承受挫折和适应能力．积极的情绪,自我和对他人的态度以及人际关系等六个方面的特征;大学生认为健全人格特征中较重要和具有一致性的特征是责任心、诚信、自信、自立、自强、人际关系良好、上进心,自尊、自爱等;性别因素对健全人格特征的内隐观影响十分显著．年级和年级与性别的交互作用因素对健全人格特征的内隐观影响不显著。     

Intertemporal Distributive Judgement

This paper considers the simple two-person two-period case of distributive judgement, and argues (a) that sensible intertemporal distributive principle should consider both the distribution of people's life time well-being and the distribution of people's well-being at each period and (b) that, if (a) is correct, Egalitarianism is more acceptable than Prioritarianism since the latter must choose either one.     

Partner Orientation and Speaker's Knowledge as Conflicting Parameters in Language Production

Two parameters of language production, the partner model and the mentally represented knowledge about a spatial constellation, are investigated with respect to their influence on spatial reference. At issue is whether the verbally expressed point of view in route directions is primarily influenced by the needs of the partner or by the underlying mental representation of the speaker stemming from his or her own experience with an object. Two experiments in which participants (N = 90) were asked to produce a set of route directions are reported. The experimental situation was such that the point of view of the speaker did not correspond to the point of view of the partner. The results show that more participants localize from their own point of view than from the point of view of the partner. Discussion centers on the fact that speakers do not always behave in a truly partner-oriented manner.     

Pigeons' choices in situations of diminishing returns: fixed- versus progressive-ratio schedules.

In two different discrete-trial procedures, pigeons were faced with choices between fixed-ratio and progressive-ratio schedules. The latter schedules entail diminishing returns, a feature analogous to foraging situations in the wild. In the first condition (no reset), subjects chose between a progressive-ratio schedule that increased in increments of 20 throughout a session and a fixed-ratio schedule that was constant across blocks of sessions. The size of the fixed ratio was varied parametrically through an ascending and then a descending series. In the reset condition, the same fixed-ratio values were used, but each selection (and completion) of the fixed ratio reset the progressive-ratio schedule back to its minimal value. In the no-reset procedure, the pigeons tended to cease selecting the progressive ratio when it equaled or slightly exceeded the fixed-ratio value, whereas in reset, they chose the fixed ratio well in advance of that equality point. These results indicate sensitivity to molar as well as to molecular reinforcement rates, and those molar relationships are similar to predictions based on the marginal value theorem of optimal foraging theory (e.g., Charnov, 1976). However, although previous results with monkeys (Hineline & Sodetz, 1987) appeared to minimize responses per reinforcement, the present results corresponded more closely to predictions based on sums-of-reciprocals of distance from point of choice to each of the next four reinforcers. Results obtained by Hodos and Trumbule (1967) with chimpanzees in a similar procedure were intermediate between these two relationships. Variability of choices, as well as median choice points, differed between the reset and no-reset conditions.(ABSTRACT TRUNCATED AT 250 WORDS)     

Feedback functions for variable-interval reinforcement

On a given variable-interval schedule, the average obtained rate of reinforcement depends on the average rate of responding. An expression for this feedback effect is derived from the assumptions that free-operant responding occurs in bursts with a constant tempo, alternating with periods of engagement in other activities; that the durations of bursts and other activities are exponentially distributed; and that the rates of initiating and terminating bursts are inversely related. The expression provides a satisfactory account of the data of three experiments.     

智慧的特质论与状态论：分歧、统整与新解

特质论与状态论之争是智慧研究领域新兴的热门话题。特质论认为智慧是稳定且不易干预的人格特质;状态论认为智慧是一种相对容易波动的心智状态,短期内可以改变且容易受外在情境的影响。基于人格心理学研究的“密度分布说”则为特质论与状态论之争提供了系统的整合模型。受此启发,本研究在以往理论的基础上提出“特质-状态正态分布假说”,旨在进一步补充完善“密度分布说”并为特质论与状态论研究提供新的理论视角。未来研究仍需结合多种智慧测量手段,加强纵向追踪研究,探索智慧本质观与密度分布说的关系,开展相应的跨文化研究。
