A METHOD FOR SCALING VERBAL DISQUALIFICATION

A disqualification is a message that says something “without really saying it”—one that is evasive, indirect, or effectively ambiguous in some other way. This article describes the rationale for, and development of, an objective method for measuring the degree of disqualification in brief written messages: nonexpert judges independently assess four basic elements of the message (sender, content, receiver, context) for ambiguity, by use of a physical scale of length. The raw scale values are standardized for each judge, and the reliability of these values is quite high. Research uses of the method, as well as its limitations and possible modifications, are discussed.     

语言理解中情绪的动态模拟

采用混合实验设计, 句子-图片匹配范式和动态过程再现范式, 以包含静态情绪和动态变化情绪信息的句子为实验材料, 以被试对图片的反应时间为因变量指标, 通过不同时间间隔的设置以及不同的实验程序, 探讨了语言理解中静态情绪和动态情绪的心理模拟及其时间进程。结果表明：(1)被试对情绪的心理模拟与句中的语言描述一致, 情绪语境能够激活被试的经验模拟。(2)被试在句子理解加工的初期就能迅速、即时地模拟静态情绪信息, 且这种模拟具有一定的稳定性和持久性。(3)被试可以对动态变化的情绪进行动态的心理模拟, 不过这种模拟所需的时间要长, 是在句子理解加工的后期完成的。被试对不同情绪变化方向的句子模拟受到原情绪状态的影响, 当阅读由消极情绪向积极情绪变化的句子时, 由于被试固着于原来的消极情绪而发生了模拟积极情绪的困难。     

Visual perceptual learning

Perceptual learning refers to the phenomenon that practice or training in perceptual tasks often substantially improves perceptual performance. Often exhibiting stimulus or task specificities, perceptual learning differs from learning in the cognitive or motor domains. Research on perceptual learning reveals important plasticity in adult perceptual systems, and as well as the limitations in the information processing of the human observer. In this article, we review the behavioral results, mechanisms, physiological basis, computational models, and applications of visual perceptual learning.     

公共卫生监测中的伦理原则及标准

从理论上概述了各时期监测定义的演变以及相关伦理辩论,列举了公共卫生监测所引发的普遍的伦理问题及适用的主要伦理原则,揭示了临床医学和公共卫生中伦理问题的不同。人权是个人利益和集体利益的共同基础,因此,也可能是临床伦理和公共卫生伦理的共同基础。最后,依据《世界卫生组织关于公共卫生监测中伦理问题的指南》及其他文献列出多种公共卫生伦理标准,试图在实际工作中帮助评估公共卫生监测方案在伦理上的可接受性。     

Is Cumulative Exposure to Suicide Attempts and Deaths a Risk Factor for Suicidal Behavior Among Firefighters? A Preliminary Study

The association between cumulative exposure to suicide attempts and deaths and suicidal behavior was examined in a sample of 61 professional firefighters. On average, firefighters reported 13.1 (SD = 16.6) exposures over the course of their lifetime. Cumulative exposure to suicide attempts and deaths was positively correlated with suicidal behavior (r = .38, p = .004). Moreover, firefighters with 12+ exposures were more likely to screen positive for risk of suicidal behavior (OR = 7.885, p = .02). Additional research on the potential impact of cumulative exposure to suicide attempts and deaths on firefighters' health and safety is needed.
