听觉诱发和电刺激中脑下丘诱发大鼠听因性发作的比较

用100微安、持续1至3秒的电流刺激正常大鼠的中脑下丘,每24小时刺激一次,经过20次之后,动物的听因性发作率可达75％,它与听觉诱发组的动物经过连续10次的铃声诱发后所达到的发作率(80％)十分接近,与无诱发的对照组动物的发作率相比,有显著差异。此结果进一步肯定了中脑下丘在听因性发作中的重要作用。     

独生与非独生儿童认知发展的比较研究(广州市)

为了研究中国独生子女政策可能造成的独生和非独生儿童的认知能力的差别,分别在广州七所小学一年级和五年级中选择了146名和171名独生与非独生儿童。用11项认知能力测验对这些儿童进行测查。一年级独生儿童在言语记忆和一般常识项目上的成绩优于非独生儿童。研究认为,一年级独生儿童在与一般认知能力有关的项目上具有优势。而五年级的独生儿童在认知作业成绩上,没有表现出显著性的优势。另外,独生男童在一般常识方面优于独生女童。作者用独生儿童受到较大的父母关注和投资来解释一年级独生对非独生儿童在认知方面的优势。随着儿童的自然成熟和学业教育,两者之间的差距会逐渐缩小,从而使五年级独生儿童未能在认知方面表现出明显的优势。     

气功入静过程中自发脑电波功率谱及相干函数的分析

用脑电技术和功率谱与相干函数的计算机分析方法,对78名受试者,分别进行了气功入静、一般休息和普通睡眠时的不同脑电变化规律的研究。结果表明入静过程能够使额区脑电能量在δ频段下降,在α频段上升,并在特定频率附近额枕脑电相干值增大。由此提出了入静深度指数概念,并证明了:(1)与一般休息相比,入静深度指数在练功时增大,在睡眠时下降,表示入静过程有自己的特殊规律。(2)内养功、强壮功、虚明功的入静深度指数无明显差异,说明不同练功方法均能达到入静的效果。     

肢体伤残者心理康复的试探性研究

三年来,根据接待配装假肢及康复治疗伤残病人的实际情况,我们选择了感觉、知觉和记忆三个项目,进行了测定,即:(1)伤残部位和对应部位的两点阈值测定;(2)装戴假手后提重差别阈限的测定;(3)再认能力测定。结果表明,这些测定对伤残病人的康复治疗和心理评定都有一定的参考价值。     

大学生一般结果期待对风险决策偏好的影响

以一般结果期待的双维结构观点为基础,按照一般结果期待的乐观期待和悲观期待的水平将184名大学生样本划分为明显乐观、明显悲观、双重倾向和倾向不明四个类型,进而探讨不同类型大学生在创业投资情境下一般结果期待对风险决策偏好的影响。结果表明,风险概率、描述框架与一般结果期待的交互作用显著,在低风险概率、积极框架下,双重倾向型一般结果期待大学生比其他三个类型的大学生表现出明显的风险寻求偏好。     

Can Lonely People Behave Morally? The Joint Influence of Loneliness and Empathy on Moral Identity

We examine how loneliness moderates the effect of empathy on moral identity: the extent to which being a moral person is important to an individual's identity. Results of four studies show that only lonely people have increased moral identity when they have high (vs. low) empathy; empathy does not reliably increase moral identity for nonlonely people. We demonstrate these effects with psychological measures of moral identity as well as with downstream moral behaviors in various consumer settings. Our findings are consistent with the motivation theory of loneliness and empathy: Lonely people are capable, but are not motivated to empathize.     

Positive factors associated with quality of life among Chinese patients with renal carcinoma: a cross-sectional study

Quality of life and positive psychological variables has become a focus of concern in patients with renal carcinoma. However, the integrative effects of positive psychological variables on the illness have seldom been reported. The aims of this study were to evaluate the quality of life and the integrative effects of hope, resilience and optimism on the quality of life among Chinese renal carcinoma patients. A cross-sectional study was conducted at the First Hospital of China Medical University. 284 participants completed questionnaires consisting of demographic and clinical characteristics, EORTC QLQ-C30, Adult Hope Scale, Resilience Scale-14 and Life Orientation Scale-Revised from July 2013 to July 2014. Pearson’s correlation and hierarchical regression analyses were performed to explore the effects of related factors. Hope, resilience and optimism were significantly associated with quality of life. Hierarchical regression analyses indicated that hope, resilience and optimism as a whole accounted for 9.8, 24.4 and 21.9% of the variance in the global health status, functioning status and symptom status, respectively. The low level of quality of life for Chinese renal carcinoma patients should receive more attention from Chinese medical institutions. Psychological interventions to increase hope, resilience and optimism may be essential to enhancing the quality of life of Chinese cancer patients.     

The art and science of guessing

This research examined how one affectively reacts to others' guesses at a value one cares about, such as one's income. Conventional wisdom suggests that people will feel happier upon receiving more favorable guesses (e.g., higher income) than less favorable guesses. We found the opposite pattern. We propose a model to explain the effect and identify its boundaries and report experimental evidence for the model. This research enriches existing literature on self-enhancement and yields practical implications for how to approach guessing in interpersonal communications.     

Distinction bias: misprediction and mischoice due to joint evaluation

This research identifies a new source of failure to make accurate affective predictions or to make experientially optimal choices. When people make predictions or choices, they are often in the joint evaluation (JE) mode; when people actually experience an event, they are often in the single evaluation (SE) mode. The "utility function" of an attribute can vary systematically between SE and JE. When people in JE make predictions or choices for events to be experienced in SE, they often resort to their JE preferences rather than their SE preferences and overpredict the difference that different values of an attribute (e.g., different salaries) will make to their happiness in SE. This overprediction is referred to as the distinction bias. The present research also specifies when the distinction bias occurs and when it does not. This research contributes to literatures on experienced utility, affective forecasting, and happiness.
