Remarks on an Avoidable Error in a Posteriori Testing

This article discusses a widespread error that occurs with a posteriori testing in factorial analyses of variance. Frequently, an incorrect sample size is used under the radical in the formula for computing a critical difference such as the Fisher least significance difference. This usually leads to an inappropriately large critical difference; thus, few if any significant differences are uncovered between the means. An interesting example of this error, from a journal article by Van Berschot (1979), is examined. Researchers are urged always to use under the radical the number of observations on which each mean being compared is based.     

The Name-Pronunciation Effect: Further Evidence from Chinese

This study examined the Chinese name-pronunciation effect. The easy-to-pronounce and difficult-to-pronounce Chinese names were created using the same characters in order to control for visual perceptual and conceptual fluency. In Experiment 1, participants rated each name in terms of liking, electability as a state leader, income level, and baby name preference. An additional rating of prevalence was used to estimate familiarity. In Experiment 2, participants did not read the name aloud before rating and performed intentional recall and recognition tests. In both experiments, the easy-to-pronounce names were rated higher than difficult-to-pronounce names on liking. This effect generalized to judgments of electability and baby name preference but not to prevalence and income level. There were no differences in memory performances between the two types of names. Results are discussed in terms of the boundary condition of the name-pronunciation effect and the advantage of using Chinese names to study this effect.     

Moral Motivation Based on Multiple Developmental Structures: An Exploration of Cognitive and Emotional Dynamics

Intrapersonal variability and multiplicity in the complexity of moral motivation were examined from Dynamic Systems and Self-Determination Theory perspectives. L. Kohlberg's (1969) stages of moral development are reconceptualized as soft-assembled and dynamically transformable process structures of motivation that may operate simultaneously within person in different degrees. Moral motivation is conceptualized as the real-time process of self-organization of cognitive and emotional dynamics out of which moral judgment and action emerge. A detailed inquiry into intrapersonal variation in moral motivation is carried out based on the differential operation of multiple motivational structures. A total of 74 high school students and 97 college students participated in the study by completing a new questionnaire, involving 3 different hypothetical moral judgments. As hypothesized, findings revealed significant multiplicity in the within-person operation of developmental stage structures, and intrapersonal variability in the degrees to which stages were used. Developmental patterns were found in terms of different distributions of multiple stages between high school and college samples, as well as the association between age and overall motivation scores. Differential relations of specific emotions to moral motivation revealed and confirmed the value of differentiating multiple emotions. Implications of the present theoretical perspective and the findings for understanding the complexity of moral judgment and motivation are discussed.     

汉语母语与英语母语学生英语语音意识发展趋势的比较研究

对汉语母语学生与英语母语学生英语语音意识的发展趋势进行了对比。294名汉语母语学生和109名英语母语学生参加了音节意识任务、首尾音意识任务和音位意识任务测试。研究结果表明：（1）汉语母语学生与英语母语学生发展趋势并不相同：汉语学生英语语音意识发展的迅速期为小学初期,之后发展缓慢;英语母语学生音节意识和首尾音意识随着年级的增长而增长,但音位意识则表现出不规则的变化趋势;（2）随着汉语母语学生年龄的增长,他们与英语母语学生英语语音意识之间的差距并未缩小。     

Producing and recognizing words with two pronunciation variants: Evidence from novel schwa words

This study examined the lexical representations and psycholinguistic mechanisms underlying the production and recognition of novel words with two pronunciation variants in French. Participants first learned novel schwa words (e.g., /??nyk/), which varied in their alternating status (i.e., whether these words were learned with one or two variants) and, for alternating words, in the frequency of their variants. They were then tested in picture-naming (free or induced) and recognition memory tasks (i.e., deciding whether spoken items were learned during the experiment or not). Results for free naming show an influence of variant frequency on responses, more frequent variants being produced more often. Moreover, our data show an effect of the alternating status of the novel words on naming latencies, with longer latencies for alternating than for nonalternating novel words. These induced naming results suggest that both variants are stored as lexical entries and compete during the lexeme selection process. Results for recognition show an effect of variant frequency on reaction times and no effect of variant type (i.e., schwa versus reduced variant). Taken together, our findings suggest that participants both comprehend and produce novel French schwa words using two lexical representations, one for each variant.     

汉语词汇产生中音、形、义三种信息激活的时间进程

采用图-词干扰范式和图片命名方法,探讨语音、语义、字形在汉语词汇产生中激活的时间进程与特点。选择与目标图片名称(如“羊”)具有同音(“阳”)、语义相联(“牛”)、字形相似(“丰”)或无关控制(“冷”)等四种关系的干扰字,依SOA条件呈现在将要被命名的图片上,发现图片命名时间受干扰字的影响：语义干扰效应存在于较早期的SOA(0ms)条件中,在较晚期SOA(150ms)时有很大的减弱;语音促进效应和字形促进效应同时强烈地存在于早期和晚期SOA。实验发现了词条选择(语义激活)和音位编码(语音提取)在激活时间上的重叠现象,与传统的独立两阶段模型的预期存在明显矛盾,倾向于支持交互作用理论的观点。     

Estimation of the Coefficient of Variation with Minimum Risk: A Sequential Method for Minimizing Sampling Error and Study Cost

The coefficient of variation is an effect size measure with many potential uses in psychology and related disciplines. We propose a general theory for a sequential estimation of the population coefficient of variation that considers both the sampling error and the study cost, importantly without specific distributional assumptions. Fixed sample size planning methods, commonly used in psychology and related fields, cannot simultaneously minimize both the sampling error and the study cost. The sequential procedure we develop is the first sequential sampling procedure developed for estimating the coefficient of variation. We first present a method of planning a pilot sample size after the research goals are specified by the researcher. Then, after collecting a sample size as large as the estimated pilot sample size, a check is performed to assess whether the conditions necessary to stop the data collection have been satisfied. If not an additional observation is collected and the check is performed again. This process continues, sequentially, until a stopping rule involving a risk function is satisfied. Our method ensures that the sampling error and the study costs are considered simultaneously so that the cost is not higher than necessary for the tolerable sampling error. We also demonstrate a variety of properties of the distribution of the final sample size for five different distributions under a variety of conditions with a Monte Carlo simulation study. In addition, we provide freely available functions via the MBESS package in R to implement the methods discussed.
