Reinforcement and punishment effects in concurrent schedules: A test of two models

The joint effects of punishment and reinforcement on the pigeon's key-peck response were examined in three choice experiments conducted to compare predictions of Farley and Fantino's (1978) subtractive model with those made by Deluty's (1976) and Deluty and Church's (1978) model of punishment. In Experiment 1, the addition of equal punishment schedules to both alternatives of a concurrent reinforcement schedule enhanced the preference exhibited for the more frequent reinforcement alternative. Experiment 2 demonstrated decreases in the absolute response rate for each member of a concurrent reinforcement schedule when increasing frequencies of punishment were added to each alternative. Experiment 3 found that preference for the denser of two reinforcement schedules diminished when the absolute frequencies of reinforcement were increased by a constant factor and conditions of punishment for both alternatives were held constant. Diminished preferences were obtained regardless of whether the frequency of punishment associated with the denser reinforcement schedule was greater or less than that associated with the lean reinforcement alternative. The results from all three experiments uniquely supported Farley and Fantino's (1978) subtractive model of punishment and reinforcement.     

规则多边图形的离散度、图基边数及显示条件的交互作用研究

用实验方法研究规则多边图形的离散度、图形基边数、显示条件及三因素的交互作用对图形信号认知绩效的影响。实验的自变量有：（１）图形的离散度参数;（２）图形的基边数;（３）图形的显示条件。因变量是各图形信号的平均反应时。实验的刺激材料是２５个不同离散度、不同基边数的规则多边图形。刺激材料的呈现与被试的反应记录都由计算机控制。结果表明：（１）离散度对图形信号认知绩效的影响十分显著,离散度适中及偏小的图形信号认知绩效较高;（２）图形基边数对认知绩效的影响十分显著,认知绩效反比于图形的基边数;（３）显示条件对认知绩效的影响不显著;（４）离散度与基边数的交互作用影响显著,离散度偏大的０．６,０．７图形与离散度偏小及适中的０．３,０．４,０．５图形的认知绩效在基边数大于８后出现明显的分离趋势。

Assessing empirical research in bioethics

Empirical research can aid ethical reflection in bioethics by identifying issues, by seeing how they are currently resolved, and by assessing the consequences of these current resolutions. This potential can be misused when the ethical issues in question are fundamentally non-consequentialist or when they are consequentialist but the empirical research fails to address the important consequences. An example of the former problem is some recent studies about bad consequences resulting from commercialized living kidney donor programs. These consequences could be avoided, but the crucial non-consequentialist ethical issues about exploitation and commercialization would still remain. Examples of the latter problem are provided by recent studies of the allocation of ICU beds and of physician deception, where important consequences were not adequately studied.     

SEARCH FOR BELIEFS TO LIVE BY CONSISTENT WITH SCIENCE

Abstract. Instead of separating religion and science into "mutually incompatible realms," the new macromental paradigm of behavioral science permits integration of the two within a single consistent worldview. A new form of causal determinism combines conventional "bottom-up" with emergent "top-down" causation. Traditional materialist tenets are overturned, along with the science-values dichotomy, clearing the way for a science-based value/belief system. Intrinsic ethicomoral directives emerge in which a revised sense of the sacred would help protect the evolving quality of the biosphere, and the rights and welfare of future generations. Subsequent versions of today's changing worldview raise questions of which interpretation to believe. An analysis of "New Age" thinking is called for, and a brief attempt at such analysis is included.     

中介效应检验程序及其应用

讨论了中介变量以及相关概念、中介效应的估计；比较了检验中介效应的主要方法；提出了一个检验程序，它包含了依次检验和Sobel检验。该程序检验的第一类和第二类错误率之和通常比单一检验方法小，既可以做部分中介检验，也可以做完全中介检验。作为示范例子，引入中介变量研究学生行为对同伴关系的影响。     

父母关系与子女行为异常

我们利用父母关系问卷、家庭背景问卷和行为症状量表对中国5个城市550个家庭、1493名被试者进行了调查与测试。结果表明,父亲职业、父亲文化水平、家庭的经济条件等社会经济地位因素影响父母关系：父母的社会经济地位高,父母关系好。父母婚姻状况影响父母关系：问题婚姻状态下的父母关系较差。父母关系对子女行为异常有显著影响：父母关系差,子女行为异常水平高。     

On kristof's test for a linear relation between true scores of two measures

The hypothesis that two variables have a perfect disattenuated correlation and hence measure the same trait, except for errors of measurement, is discussed. Equivalently, the underlying variables, the true scores, are related linearly. We show that several previously proposed ad hoc tests are in fact likelihood ratio tests. The cases when the linear relation is specified and when it is unspecified are both discussed.This work was done while the author was at Purdue University Under Air Force Grant AFOSR-72-2350B.     

Individual distributions under ordinal measurement

For ordinal measurement the concept of an individual propensity distribution is developed. For any given individual the mean of this distribution is his true score, for which estimation procedures are discussed. Two measures of individual dispersion are considered and their distributions derived in the null case. These measures are shown to be counterparts at the individual level of Kendall's tau and Spearman's rho. Estimation of the two dispersion measures from sample data is investigated, and the relation of these estimates to the variance of the individual propensity distribution is derived.
