Power of the likelihood ratio test in covariance structure analysis

A procedure for computing the power of the likelihood ratio test used in the context of covariance structure analysis is derived. The procedure uses statistics associated with the standard output of the computer programs commonly used and assumes that a specific alternative value of the parameter vector is specified. Using the noncentral Chi-square distribution, the power of the test is approximated by the asymptotic one for a sequence of local alternatives. The procedure is illustrated by an example. A Monte Carlo experiment also shows how good the approximation is for a specific case.This research was made possible by a grant from the Dutch Organization for Advancement of Pure Research (ZWO).

Assessing structure building in college classrooms at scale

Structure building refers to the way in which people construct meaning from incoming information by creating a foundation of mental nodes, mapping incoming information to the foundational structure, and shifting to a new structure when necessary. Structure building ability has been shown to moderate learning both in laboratory-based and classroom-based research (e.g., use of outlines for effective note-taking and course final grades, respectively). However, measurement of structure building can be resource intensive. The purpose of the present study was to evaluate a shortened, scalable measure of structure building (developed by a textbook publisher) in a real-world context. The results are consistent with the hypothesis that this tool, embedded in the online ancillary materials accompanying a textbook, can be used to measure a variable that is relevant to students' learning in introductory psychology courses.     

Structure factorielle et qualités psychométriques de la version française du questionnaire d’auto-description pour adultes (adult self-report) d’Achenbach et Rescorla

Because of the frequent comorbidities, clinicians need to get a comprehensive picture of the behavioral and emotional problems presented by their patients, but structured interviews allowing for such a survey are time consuming and sometimes tedious, and no French language self-report questionnaire is currently available. The aim of the present study was to verify the factorial structure and some psychometric properties of the French version of the Achenbach and Rescorla's (2003) adult self-report (ASR), which is designed to assess 120 behavioral and emotional problems. We collected ASR forms completed by 905 students enrolled in a university having schools of humanities, social sciences, sports, laws and economics (699 women, 669 students in psychology, 862 aged 18–35 years). The confirmatory factor analyses yielded the expected eight-factor structure (RMSEA = .037; CFI = .931). The internal consistency was similar to the original, and the test-retest reliability was satisfactory. French subjects, especially men, scored higher than their American counterparts on several scales, but the effect sizes were small to medium. French women and men's scores differed only on the Rule-Breaking Behavior scale, with men scoring higher; however, students in psychology, whichever was their gender, scored higher than other students on scales measuring internalizing problems and attention problems. Despite some limitations, the main of which is that all participants were students from the same university, these results speak in favor of the use of the French adult self-report in both research and clinical practice.     

Effects of achievement contexts on the meaning structure of emotion words

Little is known about the impact of context on the meaning of emotion words. In the present study, we used a semantic profiling instrument (GRID) to investigate features representing five emotion components (appraisal, bodily reaction, expression, action tendencies, and feeling) of 11 emotion words in situational contexts involving success or failure. We compared these to the data from an earlier study in which participants evaluated the typicality of features out of context. Profile analyses identified features for which typicality changed as a function of context for all emotion words, except contentment, with appraisal features being most frequently affected. Those context effects occurred for both hypothesised basic and non-basic emotion words. Moreover, both data sets revealed a four-dimensional structure. The four dimensions were largely similar (valence, power, arousal, and novelty). The results suggest that context may not change the underlying dimensionality but affects facets of the meaning of emotion words.     

Driving anger and its relationship with aggressive driving among Chinese drivers

Driving anger poses a serious threat to road safety. Increasing attention is being paid on this issue, with driving anger usually measured by a 14-item version of the Driving Anger Scale (short DAS). However, driving anger problem in China has received limited research attention and there is no corresponding Chinese version of the short DAS. This study adapted the short DAS for use with Chinese drivers and investigated the relationship between driving anger and aggressive driving with an Internet-based survey conducted to a sample of Chinese drivers. The Confirmatory Factor Analysis results showed that a three-factor DAS structure provided a good fit to the data obtained, with the three subscales used being hostile gesture, safety-blocking and arrival-blocking. The hostile gesture subscale and arrival-blocking subscale were positive predictors while the safety-blocking subscale was a negative predictor of aggressive driving. In China, the overall driving anger was lower but its association with aggressive driving was stronger, than that in western countries. These findings provide important insights into causes and consequences of driving anger for the development of effective strategies to reduce driving anger and to enhance road safety.     

Connections Among Identity,Attachment, and Psychological Dating Aggression During Adolescence

The collective influence of identity styles and romantic attachment insecurity on psychological dating aggression was examined for 1,975 adolescents living in a southern state in the United States. Informational identity style related negatively to psychological dating aggression, but anxious romantic attachment related positively to this behavior. Diffuse-avoidant identity style and using psychological dating aggression were associated positively, whereas normative identity style and receiving psychological dating aggression were associated negatively. In addition, the combination of high informational or normative identity style with high avoidant romantic attachment was linked to lower psychological dating aggression. Our findings build on the previously noted parallelism between identity styles and romantic attachment insecurity by showing how they work together to explain variability in psychological dating aggression.     

Achievement-oriented and dependency-oriented parental psychological control: An examination of specificity to middle childhood achievement and dependency-related problems

Middle childhood is considered a sensitive phase for the development of both dependency and achievement-related problems. In order to target efficient prevention and treatment, it is necessary to identify unique associations with possible precursors. This study hypothesized that children’s dependency-related problems (i.e., separation anxiety and generalized anxiety) would uniquely relate to parental dependency-oriented psychological control and that children’s achievement-related problems (i.e., extrinsic motivation and maladaptive perfectionism) would uniquely relate to parental achievement-oriented psychological control. The study included 180 elementary school children. Results showed that higher levels of children’s separation anxiety uniquely related to more parental dependency-oriented psychological control, while higher levels of children’s extrinsic motivation uniquely related to more parental achievement-oriented psychological control. Contrary to the expectations, higher levels of children’s maladaptive perfectionism were associated with both dimensions of parental psychological control, and children’s generalized anxiety was not associated with any dimension. Study implications are discussed.     

De-polarizing verbal irony

In three studies participants were asked to rate the degree of irony perceived in comments relating to five variations of a scenario, ranging from one pole to the opposite pole and passing through three in-between states. In study 1, the comments pertained to the polar extremes of a dimension, e.g. “It’s uphill!” stated with reference to varying degrees of steepness both uphill and downhill (i.e. steep, slightly steep, flat, slightly sloping downhill and steeply sloping downhill). In study 2, the comments were of an “intermediate” nature (e.g. “This hill is neither uphill nor downhill!”) and, as in Study 1, they were used to refer to the same five varying degrees of the same dimension. Study 3 involved the stimuli from both of the first two experiments in a between-participants design.

The results consistently demonstrated that verbal irony does not only apply to (weakly or strongly) polarised statements and situations, but it can also apply to intermediate comments and experiences. The perceptual structure of the dimensions involved modulates the effect.

面孔重复启动效应:知觉结构和语义表征的贡献

以30名大学生为被试,探讨了熟悉和陌生的正倒立面孔对重复启动效应的影响,以此考察知觉结构和语义表征对面孔重复启动的贡献.结果表明:(1)熟悉面孔的重复启动既存在知觉启动也存在语义启动,而不熟悉面孔仅仅存在知觉启动.(2)知觉结构和语义表征对启动效应的贡献是联合的,而不是分离的;在熟悉面孔中,语义表征对重复启动的贡献大于知觉结构的贡献.(3)知觉结构和语义表征对重复启动的贡献与加工阶段有关.知觉结构在初始阶段起作用,随后作用逐渐减弱;而语义表征存在于信息加工的整个过程.
