Generalized structured component analysis

We propose an alternative method to partial least squares for path analysis with components, called generalized structured component analysis. The proposed method replaces factors by exact linear combinations of observed variables. It employs a well-defined least squares criterion to estimate model parameters. As a result, the proposed method avoids the principal limitation of partial least squares (i.e., the lack of a global optimization procedure) while fully retaining all the advantages of partial least squares (e.g., less restricted distributional assumptions and no improper solutions). The method is also versatile enough to capture complex relationships among variables, including higher-order components and multi-group comparisons. A straightforward estimation algorithm is developed to minimize the criterion.The work reported in this paper was supported by Grant A6394 from the Natural Sciences and Engineering Research Council of Canada to the second author.

Type of motion in inverted self-motion perception induced by a foreground stimulus

Slowly moving foreground induces an illusory self-motion perception in the same direction as its motion direction (inverted vection). In this study, the effects of motion type of the foreground stimulus on inverted vection were investigated using a sample of 3 men and 1 woman. As indices of perceived strength of the inverted vection, duration and estimated magnitude were measured. Analysis of the psychophysical experiment indicated that a translating foreground induced inverted linear vection in the same direction as the stimulus motion. However, a rotating foreground did not induce an inverted roll vection. Statistical analyses indicate that there is a significant difference between two foreground motion conditions (Duration: t3=14.54, p <.01; Estimation: t3=16.92, p<.01). This result supports the hypothesis that eye-movement information is responsible for the occurrence of inverted vection.     

Asymmetric recognition of pictures of cats as a function of age in 4-, 5-, and 6-year-old children

In the present study it was investigated whether children recognized deletions more accurately than additions in pictures of animate objects as a function of age between 4 and 6 years. Children, presented pictures of cats with features added to or deleted from the original pictures, judged whether the pictures were the same or different as those in a test of recognition. Analysis showed both 5-yr.-olds and 6-yr.olds discovered deletions more accurately than additions. This asymmetric effect is in accord with that of adults, with whom the same stimuli were used in earlier research, but are contrary to previous studies in which additions were recognized more accurately than deletions when inanimate objects were stimuli. Asymmetric effects, that is, greater recognition accuracy for deletions may be related to children's being uncomfortable about modified pictures of animals.     

On a test of dimensionality in redundancy analysis

Lazraq and Cléroux (Psychometrika, 2002, 411–419) proposed a test for identifying the number of significant components in redundancy analysis. This test, however, is ill-conceived. A major problem is that it regards each redundancy component as if it were a single observed predictor variable, which cannot be justified except for the rare situations in which there is only one predictor variable. Consequently, the proposed test leads to drastically biased results, particularly when the number of predictor variables is large, and it cannot be recommended for use. This is shown both theoretically and by Monte Carlo studies.The work reported in this paper was supported by Grant A6394 to the first author from the Natural Sciences and Engineering Research Council of Canada.     

Persistence of Initial Misanalysis With No Referential Ambiguity

Previous research reported that in processing structurally ambiguous sentences comprehenders often preserve an initial incorrect analysis even after adopting a correct analysis following structural disambiguation. One criticism is that the sentences tested in previous studies involved referential ambiguity and allowed comprehenders to make inferences about the initial interpretation using pragmatic information, suggesting the possibility that the initial analysis persisted due to comprehenders' pragmatic inference but not to their failure to perform complete reanalysis of the initial misanalysis. Our study investigated this by testing locally ambiguous relative clause sentences in Japanese, in which the initial misinterpretation contradicts the correct interpretation. Our study using a self‐paced reading technique demonstrated evidence for the persistence of the initial analysis with this structure. The results from an eye‐tracking study further suggested that the phenomenon directly reflected the amount of support given to the initial incorrect analysis prior to disambiguating information: The more supported the incorrect main clause analysis was, the more likely comprehenders were to preserve the analysis even after the analysis was falsified. Our results thus demonstrated that the preservation of the initial analysis occurs not due to referential ambiguities but to comprehenders' difficulty to fully revise the highly supported initial interpretation.     

Differences in Internalizing Symptoms Across Specific Ethnic Minority Groups: An Analysis Across Chinese American,Filipino American,Japanese American,Native Hawaiian,and White Youth

Research to date on child and adolescent anxiety and depression have focused predominantly on major ethnic groups. Very few studies to date have been conducted on specific ethnic minority groups and the relatively few studies on these ethnic minority samples have produced mixed findings. The following question therefore still remains: Do specific ethnic subgroups differ with respect to their expression of anxiety and depression? And do these differences differ as a function of reporter type (i.e., youth versus parent)? If the expression of internalizing symptoms differs across specific ethnic subgroups, these differences could inform approaches to assessing and treating these populations. In the current study, we therefore examined ethnic differences in anxiety and depression symptoms in ethnic subgroups. A total of 629 children and adolescents from various public and private schools, aged 8–18 years (M = 12.37, SD = 2.8) and their caregivers completed anxiety and depression scales. Multiple indicators, multiple causes confirmatory factor analysis revealed that the following specific ethic subgroups were associated with significantly greater anxiety and depression relative to Caucasian youth: Chinese American, Filipino American, Japanese American, and Native Hawaiian. These results were found only among parent (but not youth) reports. Age and low SES status was also associated with more internalizing problems among Chinese, Filipino, and Japanese American youth. Implications related to ethnic minority subgroup differences and the role of multi-informant reports in understanding the relationship between anxiety, depression and ethnic minority subgroups are discussed.     

Teamwork and flow proneness mitigate the negative effect of excess challenge on flow state

Flow theory postulates that flow experience is the most intense under high-challenge/high-skill conditions, whereas an excess of challenge is aversive. This study explores potential moderators that may offset the negative impact of overly high challenge on flow state. The literature suggests that a situational factor, teamwork, and a dispositional factor, flow proneness, may moderate the relationship between challenge and flow state. We tested these moderators with Hong Kong Chinese students whose optimal condition for experiencing flow was biased toward low-challenge/high-skill. A total of 128 participants played puzzles in three challenge levels both alone and in pairs. Although challenge level was negatively associated with flow state, dyadic (team) game (compared with solitary game) and flow proneness mitigated the negative relationship between challenge and flow state. These findings shed light on factors that promote enjoyment in challenging activities even among people in cultures that are prudent about challenges.
