The Japanese language has single/geminate obstruents characterized by durational difference in closure/frication as part of the phonemic repertoire used to distinguish word meanings. We first evaluated infants' abilities to discriminate naturally uttered single/geminate obstruents (/pata/ and /patta/) using the visual habituation-dishabituation method. The results revealed that 9.5-month-old Japanese infants were able to make this discrimination, t(21) = 2.119, p = .046, paired t test, whereas 4-month-olds were not, t(25) = 0.395, p = .696, paired t test. To examine how acoustic correlates (covarying cues) are associated with the contrast discrimination, we tested Japanese infants at 9.5 and 11.5 months of age with 3 combinations of natural and manipulated stimuli. The 11.5-month-olds were able to discriminate the naturally uttered pair (/pata/ vs. /patta/), t(20) = 4.680, p < .000, paired t test. Neither group discriminated the natural /patta/ from the manipulated /pata/ created from natural /patta/ tokens: For 9.5-month-olds, t(23) = 0.754, p = .458; for 11.5-month-olds, t(27) = 0.789, p = .437, paired t tests. Only the 11.5-month-olds discriminated the natural /pata/ and the manipulated /patta/ created from /pata/ tokens: For 9.5-month-olds, t(24) = 0.114, p = .910; for 11.5-month-olds, t(23) = 2.244, p = .035, paired t tests. These results suggest that Japanese infants acquire a sensitivity to contrasts of single/geminate obstruents by 9.5 months of age and that certain cues that covary with closure length either facilitate or interfere with contrast discrimination under particular conditions. 相似文献

The contemporary development of psychometric theories and information technologies enables students to work on algorithm-based personalized tests in classroom settings. This study aims to investigate the relationship between students' achievement goals and what they prefer as “personalized problems” in computer-adaptive tests. We theoretically contrast achievement goals with developing competency through mastery and demonstrating competency through performance goals. We asked elementary and secondary school students to work on a computer-adaptive test and to complete questionnaires about what they prefer as “personalized problems” in computer-adaptive tests. The results revealed that while mastery goals positively predicted preference for challenging problems, performance goals positively predicted preference for problems that guaranteed students’ success. Moreover, only the preference for challenging problems positively predicted the intention to take computer-adaptive tests in the future. These results suggest that simply introducing a computer-adaptive test into the classroom may not be effective. We discuss how educational technologies should be integrated into human teaching activities. 相似文献

The multivariate genetic and environmental structure of Cloninger's Temperament and Character Inventory (TCI) was investigated in a sample of 617 pairs of adolescent and young adult twins from Japan. Additive genetic factors accounted for 22% to 49% of the variability on all TCI temperament scales. Although the theory predicts lower heritability for the character scales, all character subscales had a substantial genetic contribution, and nonshared environmental influences accounted for the remainder. Multivariate genetic analyses showed that several subscales used to define one dimension shared a common genetic basis with subscales defining others. Using the degree of shared genetic influence as the basis to rearrange the TCI subscales into new dimensions, it was possible to create genetically independent scales. The implications for personality measurement, theory, and molecular genetic research are discussed. 相似文献

The purpose of this study is to examine how external conformity affect internal conformity in the conditions in which the degree of discrepancy between majority opinion and physical reality are different. The 106 subjects were divided into eight groups of 2 (male and female) × 2 (high external conformer and low one) × 2 (large discrepancy and small one). We found the effect of interaction between discrepancy condition and external conformity to internal conformity. 相似文献

Unless data are missing completely at random (MCAR), proper methodology is crucial for the analysis of incomplete data. Consequently, methods for effectively testing the MCAR mechanism become important, and procedures were developed via testing the homogeneity of means and variances–covariances across the observed patterns (e.g., Kim & Bentler in Psychometrika 67:609–624, 2002; Little in J Am Stat Assoc 83:1198–1202, 1988). The current article shows that the population counterparts of the sample means and covariances of a given pattern of the observed data depend on the underlying structure that generates the data, and the normal-distribution-based maximum likelihood estimates for different patterns of the observed sample can converge to the same values even when data are missing at random or missing not at random, although the values may not equal those of the underlying population distribution. The results imply that statistics developed for testing the homogeneity of means and covariances cannot be safely used for testing the MCAR mechanism even when the population distribution is multivariate normal. 相似文献

J. M. Digman (1997) proposed that the Big Five personality traits showed a higher-order structure with 2 factors he labeled alpha and beta. These factors have been alternatively interpreted as heritable components of personality or as artifacts of evaluative bias. Using structural equation modeling, the authors reanalyzed data from a cross-national twin study and from American cross-observer studies and analyzed new multimethod data from a German twin study. In all analyses, artifact models outperformed substance models by root-mean-square error of approximation criteria, but models combining both artifact and substance were slightly better. These findings suggest that the search for the biological basis of personality traits may be more profitably focused on the 5 factors themselves and their specific facets, especially in monomethod studies. 相似文献

It has been suggested that poisoned conspecifics function as aversive unconditioned stimuli for rats. The present study examined whether the prior acquisition of food aversion could enhance this effect. In phase 1, subjects were given pairings of cocoa‐flavored pellets and a toxin. In phase 2, they were given the cocoa‐flavored pellets and later presented with a poisoned or nonpoisoned conspecific. Subsequent testing involved a choice between the cocoa‐flavored pellets and regular pellets. Prior exposure to a poisoned conspecific prevented extinction of the conditioned aversion. In contrast, exposure to a nonpoisoned conspecific allowed extinction of the conditioned aversion. These findings suggest that a rat's reaction to a stressed conspecific is affected by their prior experience of aversive events. 相似文献

Introducing the ways of cultivating mental balance, B. A. Wallace and S. L. Shapiro attempted to build bridges between Buddhism and psychology. Their systematic categorization of Buddhist teachings and extensive review of empirical support from Western psychology are valuable for future study. However, it remains a matter of concern that some more profound parts of Buddhist philosophy can be disregarded by focusing only on practical aspects of Buddhism within the context of mental health. In this comment, the authors briefly address four substantial themes to be considered: reality, identity, causality, and logicality. They suggest that the way to interpret Buddhism as techniques for well-being would certainly be viable in encouraging the study of Buddhist teachings in psychology. Yet, such attempts should not result in superficial imports and applications of Buddhist practices but give due weight to the deeper philosophical issues to build more solid bridges between Buddhism and psychology. 相似文献
