心理学实验研究的效果大小

从"心理学实验数据处理"的角度,我们可以把"效果大小"理解为"是指在心理学实验报告中反映‘自变量’对‘因变量’所产生的影响有多大的统计指标"。这一统计指标需要在掌握"虚无假设分布"和"备择假设分布"这两个抽样分布原理的基础上才能得以准确的理解,并因此知道我们在"对心理学实验数据处理过程中通过假设检验进行推断统计"之后报告研究结果时为什么需要使用这一指标。心理学实验数据处理过程中使用不同的检验方法具有与该方法相应的不同的效果大小指标,每一种检验方法也可以使用不同的指标来反映其实验处理的效果大小。对此,就"心理统计学"提到的四种主要假设检验方法所得推断结果应该使用何种"效果大小"指标更为合适提出了我们的建议。     

不同心理一致感个体对情绪信息的注意偏向

研究采用线索-靶子任务,考察高、低心理一致感个体对情绪信息的注意偏向特点。结果显示:(1)在有效提示下,高心理一致感个体对积极情绪表现出稳定的注意警觉,对消极情绪的注意偏向不稳定,低心理一致感个体对积极和消极情绪的注意偏向均不稳定;(2)在无效提示下,高心理一致感个体对积极和消极情绪的注意回避均不稳定,而低心理一致感个体对积极情绪表现出注意回避,对消极情绪表现出注意解除困难,这些注意偏向均具有中等程度的稳定性。     

The Influence of Mothers’ Emotional Expressivity and Class Grouping on Chinese Preschoolers’ Emotional Regulation Strategies

Emotional regulation within the context of social situations refers to an individual’s ability to respond to emotions in socially acceptable ways in order to adapt quickly and to maintain good interpersonal relationships. Emotional regulation is a psychological characteristic at the core of social stability. The preschool period is a stage in which children’s emotional regulation develops rapidly. Because homes and preschools are the two main places where preschoolers grow and spend their time, their mothers and peers play key roles in their social interactions. Therefore, the present study explored how the emotional regulation strategies of preschool children in China are affected by children’s class grouping and their mothers’ emotional expressivity. The participants were 182 preschoolers (ages 3–5) who were recruited for this study. The Emotional Regulation Strategy Questionnaire and the Self-Expressiveness in the Family Questionnaire were used to explore preschoolers’ emotional regulation strategies and their mothers’ emotional expressivity, respectively. The study results are as follows. (1) As they develop, preschool children use more positive emotional regulation strategies and fewer negative emotional regulation strategies. (2) Children in mixed-age classes use fewer passive reaction strategies than children in same-age classes do. For replacement activity strategies, only 4-year-old children in mixed-age classes score higher than children in same-age classes. (3) Mothers’ tendencies toward positive emotional expression can positively predict their children’s use of positive emotional regulation strategies, and their displays of negative emotions can positively predict their children’s use of negative emotional regulation strategies.     

Media influence on drive for thinness,body satisfaction,and eating attitudes among young women in Hong Kong and China

The present study examined the impact of thin-ideal media exposure on Chinese women’s drive for thinness, attitudes towards body shape, and eating attitude. Women were assigned to one of two video conditions, which portrayed the thin-ideal (experimental) or was neutral (control group), in terms of content. A total of 83 young women from Hong Kong (N = 38) and Shanghai (N = 45), aged between 18 and 25 years (M_age = 22.7) participated in the study. A significant interaction was observed between the experimental video condition and location. Hong Kong women in the experimental group experienced greater levels of body dissatisfaction than Shanghai women exposed to the same condition. Exposure to thin-ideal media produced an increase in drive for thinness, body dissatisfaction and problematic eating attitudes regardless of location, with a greater immediate impact shown in Hong Kong women.     

Study of posed emotion in facial EMG asymmetry

37 subjects' facial electromyographic activity at the corrugator and zygomatic muscle regions were recorded while they were posing with happy and sad facial expressions. Analysis showed that the mean value of EMG activity at the left zygomatic muscle region was the highest, followed by the right zygomatic, left corrugator, and right corrugator muscle regions, while a happy facial expression was posed. The mean value of EMG activity at the left corrugator muscle region was the highest, followed by those for the right corrugator, left zygomatic, and right zygomatic muscle regions while a sad facial expression was posed. Further analysis indicated that the power of facial EMG activity on the left side of the face was stronger than on the right side of the face while posing both happy and sad expressions.     

Involuntary awareness and implicit priming: role of retrieval context

This study examined the role of retrieval context in implicit priming by manipulating percentage of word-stem index as shallow and deep processing while performing a word-stem completion task. 80 subjects were randomly divided into four groups each of 20 subjects: shallow processing or deep processing with few retrieval indices, and shallow processing or deep processing with many retrieval indices. Analysis indicated that proportion of word-stem completion was significantly higher for studied words than for nonstudied words in all four groups and that the subjects in the groups with many retrieval indices had a significantly increased proportion of word-stem completion between studied and nonstudied words than those in the groups with few retrieval indices. Postquestionnaire analysis indicated that more previously studied items were retrieved if many studied items were available during implicit word-stem completion and that only a small proportion of word-stem completion was finished with studied words by the subjects who were aware of the prior studied and test word relations in all four groups. It was concluded that having more studied words retrievable contributed to more being retrieved and that involuntary awareness had very limited influence on the priming in the implicit word-stem completion.     

Social desirability bias in diary panels is evident in panelists' behavioral frequency

The purpose was to analyze a large-scale database, a national sample of 1108 heads of households collected by AT&T, to show that behavioral frequencies of the activities of consumer diary panelists may regress toward the population mean during the diary-keeping period given social desirability bias produced by the conditioning effect of keeping diaries. This effect is distinguished from regression toward the mean, a statistical phenomenon reflecting happenstance of extreme initial values. Social desirability bias is demonstrated in two ways-by observing decreasing coefficients of variation over time and by detecting a greater proportion of panelists' behavioral frequencies moving toward the population mean than moving away from it. Both cannot be explained by regression toward the mean. Social desirability bias was manifest only during the early stages of the diary-keeping period and only for activities high in involvement. The presence of social desirability bias in diary panels implies that, when people are subjected to observation, diary observations may be contaminated, leading to the mistaken impression that the population is more homogeneous than it actually is. Thus it is important for researchers to monitor the diary panel carefully to detect social desirability bias when engaged in longitudinal studies.
