Mental health condition of the only-child: a study of urban and rural high school students in China 总被引:1,自引:0,他引:1
The mental health of the only-child continues to generate interest in research literature. The present study examines the issue in China, where the one-child phenomenon is highest due to deliberate government policy. Subjects are 299 and 333 students in two high-rank high schools in urban Harebin and rural Qing an Xian, respectively (mean age = 17.2 years). Both locations are in the Heilongjiang Sheng Province of China. Results showed that urban only-children experienced significantly lower love awareness from family, higher neurotic and social depression, trait anxiety, perceived stressors, and interpersonal dependency than did urban non-only children. No significant differences were found in the rural only- and non-only children. Low love awareness from parents and peers was associated with high negative mental health conditions in the children. Low love awareness also precipitated perceived stressors which resulted in negative mental health in the covariance structure analysis. 相似文献

Prenatal cocaine and opiate exposure are thought to subtly compromise social and emotional development. The authors observed a large sample of 236 cocaine-exposed and 459 nonexposed infants (49 were opiate exposed and 646 nonexposed) with their mothers in the face-to-face still-face paradigm. Infant and maternal behaviors were microanalytically coded. No opiate-exposure effects were detected. However, mothers of cocaine-exposed infants showed more negative engagement than other mothers. The cocaine-exposed dyads also showed higher overall levels of mismatched engagement states than other dyads, including more negative engagement when the infants were in states of neutral engagement. Infants exposed to heavier levels of cocaine showed more passive-withdrawn negative engagement and engaged in more negative affective matching with their mothers than other infants. Although effect sizes were small, cocaine exposure, especially heavy cocaine exposure, was associated with subtly negative interchanges, which may have a cumulative impact on infants' later development and their relationships with their mothers. 相似文献

Texture gradients can reveal surface orientation in a manner similar to shape from shading, and therefore provide an important cue for object recognition. In this study, we tested whether a complex 3-D object, such as a face, can be identified from texture gradients alone. The stimuli were laser-scanned faces for which the texture element was a fractal-noise pattern mapped onto the 3-D surface. An eight-alternative forced choice task was used in which participants matched a face defined by texture gradients to one of eight faces defined by shape from shading (Experiment 1) or by texture gradients (Experiment 2). On average, participants scored 24% and 18%, respectively, above chance in these experiments. Although this performance was much poorer than the performance based entirely on shape-from-shading stimuli (Experiment 3), the results suggest that texture gradient information may be used to recover surface geometry of complex objects. 相似文献

To study the relationship between visual perception of magnitude of wrinkles and geometrical parameters of surfaces, four potentially relevant parameters of the surface profile were considered: the variance (sigma2), the cutting frequency (Fc), the effective disparity curvature (Dce) of the wrinkled surface over the eyeball distance of the observer, and the frequency component of the disparity curvature (Dcf). Analysis of garment seams with varying amount of pucker showed that, while the logarithm for each of these four parameters has a strong linear relationship with the visually perceived magnitude of wrinkles, following the Fechner Law, the effective disparity curvature (Dce) and the frequency component of the disparity curvature (Dcf) with visual perception appeared stronger. This modeling may be an objective method for measuring magnitude of surface wrinkles. 相似文献

The lexical constituency model: some implications of research on Chinese for general theories of reading 总被引:13,自引:0,他引:13
The authors examine the implications of research on Chinese for theories of reading and propose the lexical constituency model as a general framework for word reading across writing systems. Word identities are defined by 3 interlinked constituents (orthographic, phonological, and semantic). The implemented model simulates the time course of graphic, phonological, and semantic priming effects, including immediate graphic facilitation followed by graphic inhibition with simultaneous phonological facilitation, a pattern unique to the Chinese writing system. Pseudocharacter primes produced only facilitation, supporting the model's assumption that lexical thresholds determine phonological and semantic, but not graphic, effects. More generally, both universal reading processes and writing system constraints exist. Although phonology is universal, its activation process depends on how the writing system structures graphic units. 相似文献

This study tested whether multiple-object tracking-the ability to visually index objects on the basis of their spatiotemporal history-is scene based or image based. Initial experiments showed equivalent tracking accuracy for objects in 2-D and 3-D motion. Subsequent experiments manipulated the speeds of objects independent of the speed of the scene as a whole. Results showed that tracking accuracy was influenced by object speed but not by scene speed. This held true whether the scene underwent translation, zoom, rotation, or even combinations of all 3 motions. A final series of experiments interfered with observers' ability to see a coherent scene by moving objects at different speeds from one another and by distorting the perception of 3-D space. These reductions in scene coherence led to reduced tracking accuracy, confirming that tracking is accomplished using a scene-based, or allocentric, frame of reference. 相似文献

Three studies examine the psychometric properties (i.e., the test-retest reliability, convergent, and discriminant validity) of Fraley, Waller, and Brennan's Revised Experiences in Close Relationships (ECR-R) self-report measure of romantic attachment anxiety (model of self) and avoidance (model of others). Longitudinal analyses suggest that the ECR-R provided highly stable indicators of latent attachment during a 3-week period (85% shared variance). Hierarchical linear modeling analyses further validated the ECR-R, suggesting that it explained between 30% to 40% of the between-person variation in social interaction diary ratings of attachment-related emotions experienced during interactions with a romantic partner and only 5% to 15% of that in interactions with family and friends. Guidelines are offered regarding the conditions where highly reliable and precise measures of romantic attachment, such as the ECR-R, are deemed necessary and where shorter, albeit slightly less reliable measures, such as Bartholomew and Horowitz's Relationship Questionnaire, may also be viable. 相似文献

心理学:人力资源管理和开发的一条独特途径 总被引:2,自引:0,他引:2
企业竞争中其他资源的无差异化导致了人力资源成为关注的热点问题。研究人力资源问题时,心理学应该突出自己的学科特点和优势:从个体关怀的角度出发;回答“为什么”的问题;重视理论与实务之间的联系;强调意识层面的问题。要想对管理实践起到切实的指导作用,应该掀起一场心理学理论和知识的工具化和可操作化运动。 相似文献
