Finding one's meaning: a test of the relation between quantifiers and integers in language development

We explored children’s early interpretation of numerals and linguistic number marking, in order to test the hypothesis (e.g., Carey (2004). Bootstrapping and the origin of concepts. Daedalus, 59-68) that children’s initial distinction between one and other numerals (i.e., two, three, etc.) is bootstrapped from a prior distinction between singular and plural nouns. Previous studies have presented evidence that in languages without singular-plural morphology, like Japanese and Chinese, children acquire the meaning of the word one later than in singular-plural languages like English and Russian. In two experiments, we sought to corroborate this relation between grammatical number and integer acquisition within English. We found a significant correlation between children’s comprehension of numerals and a large set of natural language quantifiers and determiners, even when controlling for effects due to age. However, we also found that 2-year-old children, who are just acquiring singular-plural morphology and the word one, fail to assign an exact interpretation to singular noun phrases (e.g., a banana), despite interpreting one as exact. For example, in a Truth-Value Judgment task, most children judged that a banana was consistent with a set of two objects, despite rejecting sets of two for the numeral one. Also, children who gave exactly one object for singular nouns did not have a better comprehension of numerals relative to children who did not give exactly one. Thus, we conclude that the correlation between quantifier comprehension and numeral comprehension in children of this age is not attributable to the singular-plural distinction facilitating the acquisition of the word one. We argue that quantifiers play a more general role in highlighting the semantic function of numerals, and that children distinguish between numerals and other quantifiers from the beginning, assigning exact interpretations only to numerals.     

A cross-cultural comparison of the coexistence and domain superiority of individuating and relating autonomy

The consensus definition of autonomy in the psychological literature emphasizes self-governance through free volition, not separation or independence from others. Since the concept of self may differ cross-culturally, several researchers have tried to incorporate types of self into the notion of autonomy; however, only the dual model of autonomy has been able to do this while retaining an emphasis on volition. The dual model describes two distinct forms of autonomy-individuating and relating-each with superior function in a specific domain of individual functioning. Individuating autonomy represents a volitional capacity to act against social constraints and offers a route to achieve an independent self-identity by expressing individualistic attributes and distinctions. Relating autonomy represents a volitional capacity to act by emphasizing the harmony of self-in-relation-to-others, the quality of interpersonal relationships, and self-transcendence. These two forms of autonomy have been shown to coexist at the individual level in a Taiwanese sample. This study takes the next step, with a cross-cultural test of the coexistence and domain superiority hypotheses of individuating and relating autonomy. Participants included 306 college students from Taiwan and 183 college students from the United States. Structural equation modelling by multigroup analyses confirmed the cross-cultural equivalence of the two-factor individuating autonomy and relating autonomy measurement model. Across both samples the two forms of autonomy were shown to be mutually inclusive and not exclusive or independent. The domain-superior function of each form of autonomy was also confirmed cross-culturally; each form of autonomy has a dominant, but not necessarily exclusive, domain of functioning. Specifically, individuating autonomy was more associated with intrapersonal than interpersonal domain dependent variables, while relating autonomy was more associated with interpersonal than intrapersonal domain dependent variables. Limitations of the study and considerations for future research are discussed.     

Genetic and environmental stability differs in reactive and proactive aggression

The aim of this study was to examine stability and change in genetic and environmental influences on reactive (impulsive and affective) and proactive (planned and instrumental) aggression from childhood to early adolescence. The sample was drawn from an ongoing longitudinal twin study of risk factors for antisocial behavior at the University of Southern California (USC). The twins were measured on two occasions: ages 9–10 years (N=1,241) and 11–14 years (N=874). Reactive and proactive aggressive behaviors were rated by parents. The stability in reactive aggression was due to genetic and nonshared environmental influences, whereas the continuity in proactive aggression was primarily genetically mediated. Change in both reactive and proactive aggression between the two occasions was mainly explained by nonshared environmental influences, although some evidence for new genetic variance at the second occasion was found for both forms of aggression. These results suggest that proactive and reactive aggression differ in their genetic and environmental stability, and provide further evidence for some distinction between reactive and proactive forms of aggression.

Developmental shifts in fMRI activations during visuospatial relational reasoning

To investigate maturational plasticity of fluid cognition systems, functional brain imaging was undertaken in healthy 8-19 year old participants while completing visuospatial relational reasoning problems similar to Raven's matrices and current elementary grade math textbooks. Analyses revealed that visuospatial relational reasoning across this developmental age range recruited activations in the superior parietal cortices most prominently, the dorsolateral prefrontal, occipital-temporal, and premotor/supplementary cortices, the basal ganglia, and insula. There were comparable activity volumes in left and right hemispheres for nearly all of these regions. Regression analyses indicated increasing activity predominantly in the superior parietal lobes with developmental age. In contrast, multiple anterior neural systems showed significantly less activity with age, including dorsolateral and ventrolateral prefrontal, paracentral, and insula cortices bilaterally, basal ganglia, and particularly large clusters in the midline anterior cingulate/medial frontal cortex, left middle cingulate/supplementary motor cortex, left insula-putamen, and left caudate. Findings suggest that neuromaturational changes associated with visuospatial relational reasoning shift from a more widespread fronto-cingulate-striatal pattern in childhood to predominant parieto-frontal activation pattern in late adolescence.     

应对策略和社会支持对提高哮喘患者生活质量的作用

探讨应对策略及社会支持在心理干预对哮喘患者生活质量提高中的作用。采用随机对照的方法,将374名哮喘患者分为实验组（228人）及对照组（146人）,实验组除进行常规的药物治疗外,配合以系统的心理干预方法。选用生活质量问卷、医用应对问卷及社会支持评定量表对治疗前后的生活质量状况、应对策略及社会支持水平进行测量。治疗后,在生活质量总分及各维度、社会支持总分以及对社会支持的利用度上,实验组和对照组得分都有所提高．但实验组提高的分值要显著大于对照组;在回避应对上,实验组和对照组都有所降低,但对照组的降低程度要显著大于实验组,在屈服应对上,实验组和对照组也都有所降低,但实验组的降低程度要显著大于对照组。多元逐步回归分析的结果显示,屈服的降低和对社会支持利用度的提高能够显著预测哮喘患者生活质量的提高。
