管理者核心自我评价对下属组织公民行为的影响：道德式领导和集体主义导向的作用

采用配对问卷调查法, 以150位管理者和464位下属为研究对象, 考察了管理者核心自我评价对下属组织指向和人际指向公民行为的影响以及道德式领导和下属集体主义导向在其中的作用。跨层次分析结果表明：管理者核心自我评价对下属公民行为有显著正向影响; 道德式领导在管理者核心自我评价与下属公民行为关系中有中介作用; 下属集体主义导向在道德式领导与公民行为关系中具有调节作用, 表现为道德式领导对公民行为的正向影响对高集体主义导向的员工来说更明显。文章揭示了管理者核心自我评价对下属公民行为的影响效果、内在机制和作用条件, 也在一定程度上支持了领导有效性研究的特质-行为整合视角模型。     

品牌形象的消费行为学研究

品牌形象是消费者头脑中与某一品牌相关联的属性集合和相关联想,是消费者对品牌的主观反映。作者在介绍有关国内外从消费行为学的角度进行品牌形象研究的基础上,就品牌形象的消费行为学研究提出了一些新的思路。     

Parent and actometer measures of motor activity level in the young infant

Motor activity level is one dimension of infant temperament for which parental judgment can be validated against a truly independent criterion. Two studies were conducted, the first involving a 27-min sample of behavior in a structured, attention-getting situation, and the second involving a 24-hr sample of in-home behavior. In both studies, parent perception of the 3- or 4-month-old as measured by the Activity Level (AL) scale of the Rothbart Infant Behavior Questionnaire was compared to the composited readings from four mechanical motion recorders (actometers) worn, one per limb, by the infant. The AL scale did not correlate with the actometer measure, r=.05 and R=.00, and the expected convergence of the 3-month version of the IBQ activity scale with its mechanical counterpart was not found. In the 24-hr study, birth order and ponderal index were significantly correlated with 24-hr actometer scores; first-borns and thin infants were most active.     

道德情绪：道德行为的中介调节

道德情绪是心理学的一个重要研究主题。道德情绪是个体根据一定的道德标准评价自己或他人的行为和思想时所产生的一种情绪体验。它是一种复合情绪, 主要包括厌恶、移情、内疚, 羞耻等。道德情绪影响下人类会产生某些典型行为, 这主要包括道德洁净行为和道德补偿行为。心理学研究道德情绪的实验范式很多, 主要有行为回忆范式、实物或图片刺激范式、情境设置范式等。有关道德情绪的未来研究主要应注重于探讨正性道德情绪在道德发展中的作用, 探讨道德情绪对群体行为的影响, 以及探讨道德情绪在不同文化背景下的价值意义。     

脂多糖激活所致大鼠抑郁样行为及对海马神经细胞钾电流变化的影响

采用细胞因子刺激剂脂多糖(lipopolysaccharide, LPS)为免疫激活手段, 研究LPS诱导的免疫激活产生的抑郁样行为及对海马神经细胞电压依赖钾电流变化的影响。应用膜片钳技术对海马神经细胞钾电流进行全细胞记录, 比较抑郁样行为大鼠与正常大鼠钾离子通道电流密度和激活特性的变化。结果发现, 与生理盐水对照组相比, 一次LPS注射后2 hr, 实验组动物产生抑郁样行为, 同时急性观察的海马神经细胞的钾离子通道的电流密度呈现显著升高(p<0.01); 而一次LPS注射后24 hr, 动物的抑郁样行为消失, 且急性观察的海马神经细胞的钾离子通道与对照组相比较, 其电流密度和激活曲线没有显著性变化。结论：LPS诱导的抑郁样行为, 与LPS诱导的海马神经细胞电压依赖钾电流的上调在时程上同步, 提示钾离子通道可能参与免疫激活所致的抑郁样行为。     

我国民众对SARS信息的风险认知及心理行为

采用分层抽样的调查方法,对全国17个城市的4231名市民进行了SARS疫情中风险认知特征和心理行为的研究。结果发现：（1）负性信息,包括患病信息和与自身关系密切的信息,更易引起民众的高风险认知; 正性信息,包括治愈信息和政府防范措施的信息,能降低个体风险认知水平。（2）我国民众5月中旬风险认知因素空间位置分析结果表明, SARS病因处于不熟悉和难以控制一端,“愈后对身体的影响和有无传染性”处于不熟悉一端,这是引起民众风险意识的主要因素。（3）结构方程分析结果表明,SARS疫情信息是通过风险认知对个体的应对行为、心理健康产生影响的, 并初步验证了风险评估、心理紧张度、应对行为和心理健康等指标对于危机事件中民众心理行为的预测作用     

THE EFFECTS OF A GOOD-BEHAVIOR CONTRACT ON THE CLASSROOM BEHAVIORS OF SIXTH-GRADE STUDENTS1

The effects of a good-behavior contract on the on-task behavior, disruptive behavior, daily assignment completion, and weekly grades of four sixth-grade students were examined in a public school classroom. The contract consisted of presenting the students with a list of good conduct and assignment completion goals and a list of disruptive behaviors coupled with a list of rewards and penalties that could be earned. The rewards and penalties made use of existing facilities and classroom privileges. At the beginning of each morning work period, the teacher negotiated the good-behavior contract with each experimental subject. During the negotiations, the teacher emphasized student self-management and encouraged each student to earn a reward by achieving the good-conduct goals and completing the contract assignments. An isolated work area was provided to allow students the opportunity to remove themselves from their desks for a fixed period of 15 min. At the end of the work period, the teacher determined whether each student earned a choice of reward or penalty dependent on assignment completion and whether the teacher had observed disruptive behaviors. Thus, the contract permitted the student to negotiate the goal behaviors and contingencies with the teacher. Throughout the study, the students were in agreement with the teacher on whether a choice of reward or penalty had been earned. The contract was introduced for different children at different times, constituting a multiple-baseline analysis. On-task behavior and daily assignment completion increased, weekly grades were higher, and disruptive behavior decreased when the contract was in effect. Three contrast subjects were selected from the class as model students who consistently produced acceptable assignments and who did not engage in high rates of disruptive and/or off-task behaviors. When the contract was in effect for the experimental subjects, their performance compared favorably with the contrast subjects, who never received the daily contract. The results demonstrated that the contract was effective within the confines of the facilities and contingencies readily available in a public school classroom setting.     

未成年人归因的内隐特征与攻击行为

本研究使用投射法这一内隐社会认知的研究方法,考察了朱成年人罪犯群体与正常群体的攻击行为内隐社会认知过程的特征,结果表明：整体上而言,未成年人罪犯群体与正常群体的内隐归因方式存在显著差异,罪犯的内控程度要低于常人的内控程度。从而得出罪犯产生攻击性犯罪行为的原因之一是他们的归因存在偏差,支持了攻击行为成因的归因模型。未成年人男女两性在内隐的内外控方面不存在显著差异,且结果提示归因方式与女性罪犯的攻击行为没有必然联系。     

能以貌取人吗? 面孔宽高比研究述评

面孔宽高比是左右颧骨点之间的距离除以上面高所得到的比值,被认为是人类面孔性别二态特征之一。男性面孔宽高比被认为是男性睾酮水平的可信外显指标,与攻击行为、欺诈等不道德行为存在显著关联,并受到社会经济地位的调节;面孔宽高比与上进心、对内群体成员的牺牲精神等男性化积极社会行为亦存在显著关联。睾酮水平被认为是面孔宽高比和社会行为两者背后的共变因素,并引起激烈争论:面孔宽高比的性别差异在多个研究中未获支持,男性面孔宽高比与睾酮水平存在关联的直接证据亦有待进一步夯实。     

青少年感恩与问题行为的关系:学校联结的中介作用

采用青少年感恩量表、学校联结量表、青少年外化问题行为调查表和焦虑抑郁量表对1217名中学生进行调查,考察了青少年感恩与其问题行为的关系,以及学校联结的同学支持、教师支持和学校归属感三大成分在其中的系列中介作用。结果表明:(1)青少年感恩与其外化问题行为和内化问题行为(以焦虑抑郁为指标)均显著负相关;(2)学校联结三大成分在感恩与其外化和内化问题行为之间均起着系列中介作用,即感恩对青少年学校归属感既有直接影响,也通过增强同学支持和教师支持间接促进其发展,进而学校联结的三成分共同作用减少青少年的外化和内化问题行为。
