In the present study, we examined how morphemic ambiguity is resolved using the visual-world paradigm. Participants were presented with Chinese bimorphemic words containing an ambiguous morpheme (analogous to the suffix -er in teacher and taller) and performed a visual search task. Their eye-movement patterns during target detection showed that (1) without a prior context, the dominant meaning of an ambiguous morpheme was more available than the subordinate one; (2) with a dominant-biased prior context, the subordinate meaning was still activated; and (3) a subordinate-biased prior context could inhibit the dominant interpretation. Therefore, both the frequency of the intended meaning and the prior contextual biases play a role in morphemic ambiguity resolution. The results are discussed with reference to models of ambiguity resolution and recent proposals of the graded nature of morphological effects.  相似文献

Investigations of speech often involve the identification of inspiratory loci in continuous recordings of speech. The present study investigates the accuracy of perceptually determined and acoustically determined inspiratory loci. While wearing a circumferentially vented mask connected to a pneumotach, 16 participants read two passages. The perceptually determined and acoustically determined inspiratory loci were compared with the actual loci of inspiration, which were determined aerodynamically. The results showed that (1) agreement across all three judges was the most accurate of the approaches considered here for detecting inspiratory loci based on listening; (2) the most accurate pause duration threshold for detecting inspiratory loci was 250 msec; and (3) the perceptually based breath-group determination was more accurate than the acoustically based determination of pause duration. Inconsistencies among perceptually determined, acoustically determined, and aerodynamically determined inspiratory loci are not negligible and, therefore, need to be considered when researchers design experiments on breath groups in speech.  相似文献

Self-reported physical symptoms are an important marker of health and well-being, particularly among African American women. The stability of African American women’s physical symptoms or the impact of their symptoms on their children, however, has yet to be examined. This longitudinal study examined the stability of maternal self-reported physical symptoms, as well as their role in shaping child-reported physical symptoms, among 137 low-income African American families. Findings revealed that mothers’ self-reported physical symptoms were stable over 2.5 years. Mothers who reported higher levels of physical symptoms were more likely to have children who concurrently reported higher levels of symptoms. Physical symptoms reported by mothers at the first assessment also predicted child-reported physical symptoms 2.5 years later, but only for boys. Physical symptoms appear to be an important, yet understudied, symptom domain that may have significant implications for the health and well-being of African American families.  相似文献

We studied the predictive effects of psychological hardiness on successful selection in a United States federal tactical law enforcement assessment and selection (A&S) program. Seventy‐one male experienced law enforcement personnel participated in a week‐long, physically and psychologically rigorous A&S course. Dispositional Resilience Scale (DRS‐15) Total Hardiness scores predicted selection in this select sample. Age and cognitive ability moderated the predictive effects of psychological hardiness such that hardiness predicted selection in younger candidates and candidates with higher cognitive ability. Similar findings were obtained for DRS Commitment. DRS‐15 Control facet also differentiated selection in this sample but the predictive effects did not hold when age and cognitive ability were controlled. Findings extend the application of the DRS‐15 to law enforcement personnel selection and highlight the importance of examining moderating effects of psychological hardiness.  相似文献

Altered structural connectivity has been identified as a possible biomarker of autism spectrum disorder (ASD) risk in the developing brain. Core features of ASD include impaired social communication and early language delay. Thus, examining white matter tracts associated with language may lend further insight into early signs of ASD risk and the mechanisms that underlie language impairments associated with the disorder. Evidence of altered structural connectivity has previously been detected in 6‐month‐old infants at high familial risk for developing ASD. However, as language processing begins in utero, differences in structural connectivity between language regions may be present in the early infant brain shortly after birth. Here we investigated key white matter pathways of the dorsal language network in 6‐week‐old infants at high (HR) and low (LR) risk for ASD to identify atypicalities in structural connectivity that may predict altered developmental trajectories prior to overt language delays and the onset of ASD symptomatology. Compared to HR infants, LR infants showed higher fractional anisotropy (FA) in the left superior longitudinal fasciculus (SLF); in contrast, in the right SLF, HR infants showed higher FA than LR infants. Additionally, HR infants showed more rightward lateralization of the SLF. Across both groups, measures of FA and lateralization of these pathways at 6 weeks of age were related to later language development at 18 months of age as well as ASD symptomatology at 36 months of age. These findings indicate that early differences in the structure of language pathways may provide an early predictor of future language development and ASD risk.  相似文献

The shifting power relations in China after the global financial crisis are redefining masculinity for both Western and Asian men. Connell (1995) argues that in most societies a hegemonic masculinity usually exists that privileges heterosexual middle-class and economically successful men who exhibit characteristics associated with being masculine. The global financial crisis has led to a new global financial order that has created paths for people to reimagine hierarchies of class, gender, nation, race, and sexuality. “Entangled masculinities” recognizes that the intersections of class, gender, nation, race, and sexuality shape identities of male clients who buy commercial sex. The article looks specifically at clients from three niche commercial sex markets (low, mid, and high tier) in Dongguan, China. Specifically, five patterns of behavior exhibited by male clients to rationalize and assert their masculinity will be analyzed in depth: vigorous and macho; austere and essentialist; suppressive and anxious; extravagant and competitive; and refined and collaborative. This article argues clients with vigorous and macho, austere and essentialist, and suppressive and anxious behavior types are frequently found in low-end and mid-tier bars. Patrons of higher-tier bars tended to engage in extravagant and competitive and refined and collaborative behavior through expressions of wealth and power.  相似文献

This paper presents an analysis of the distribution of phonological similarity relations among monosyllabic spoken words in English. It differs from classical analyses of phonological neighborhood density (e.g., Luce &; Pisoni, 1998) by assuming that not all phonological neighbors are equal. Rather, it is assumed that the phonological lexicon has psycholinguistic structure. Accordingly, in addition to considering thenumber of phonological neighbors for any given word, it becomes important to consider thenature of these neighbors. If one type of neighbor is more dominant, neighborhood density effects may reflect levels of segmental representation other than the phoneme, particularly prior to literacy. Statistical analyses of the nature of phonological neighborhoods in terms ofrime neighbors (e.g.,hat/cat),consonant neighbors (e.g.,hat/hit), andlead neighbors (e.g.,hat/ham) were thus performed for all monosyllabic words in the Celex corpus (4,086 words). Our results show that most phonological neighbors are rime neighbors (e.g.,hat/cat) in English. Similar patterns were found when a corpus of words for which age-of-acquisition ratings were available was analyzed. The resultant database can be used as a tool for controlling and selecting stimuli when the role of lexical neighborhoods in phonological development and speech processing is examined.  相似文献

Despite the rapid increases of HIV and sexually transmitted infections (STIs) in East Asia, the sex-related knowledge among Chinese adolescents is limited and the standard of sex education is both variable and inconsistent in Hong Kong. The aim of this study is to review the overall effectiveness of the school-based or doctor-based sexual health education currently provided for Hong Kong adolescents. In 1999 - 2000, a large survey on youth risk behaviours was carried out among 15 - 18-year-old students from 21 secondary schools. Of the 8,039 questionnaires, 377 students (4.7%) admitted sexual experience. Multiple logistic regression showed that students who had received school AIDS education were found to be less likely to have sexual intercourse in the past 3 months (odds ratio, OR 0.5; 95% confidence interval, CI 0.3 - 0.9) or use drugs or alcohol before the previous intercourse (OR 0.5; 95% CI 0.3 - 0.9). They were twice as likely to discuss emotional (95% CI 1.4 - 4.0) or puberty issues (95% CI 1.1 - 3.0). Although not statistically significant, sex education by family doctors showed a similar pattern. This result provides the strongest available evidence that school-based sex education programmes can modify sexual behaviour, which, in turn, reduces risk among Chinese students.  相似文献

Prior research indicates that young children are promiscuously teleological, attributing purpose not only to artifacts, but also to living and non-living natural entities. This study further examines the role of function in children's reasoning about different object kinds by indirectly probing children's intuitions about what types of entities can be rendered functionless. Specifically, children were asked to decide whether entities that could no longer perform certain activities should be fixed/replaced (e.g. "Do you need to get a new one?"). Results reveal that young children broadly view both artificial and natural kinds that can no longer perform certain activities as needing to be fixed or replaced. These findings suggest that the teleo-functional bias not only influences children's explanatory preferences but also their category judgments.  相似文献

We examined the association between neighborhood violence and three domains of psychosocial adjustment in low-income, urban African American children: internalizing, externalizing, and physical symptoms. Based on anecdotal and empirical evidence, it was hypothesized that, relative to internalizing and externalizing problems, a stronger association would emerge between physical symptoms and neighborhood violence. Mother-reported neighborhood violence was associated with child-reported physical symptoms, but not internalizing or externalizing symptoms. Child-reported neighborhood violence was associated with child-reported internalizing, externalizing, and physical symptoms; however, neighborhood violence accounted for a greater percentage of variance in physical symptoms than the other two symptom domains. Our findings were not moderated by the age or gender of the child. We discuss the importance of physical symptoms as a marker of child adjustment in low-income, urban, African American children, as well directions for future research.  相似文献
