Suicidal ideation,parenting style,and family climate among Hong Kong adolescents

The prevalence of suicidal ideation and its relations with perceived parenting treatment and family climate was examined in 120 Hong Kong students aged 15–19 years. Fifty‐two per cent of the participants reported suicide ideation. Suicide ideation was found to be significantly associated with perceived authoritarian parenting, low parental warmth, high maternal over‐control, negative child‐rearing practices, and a negative family climate. A positive family climate may act as a buffer against developing suicide ideation in adolescents.     

儿童攻击和自我感知的关系

使用基于多水平分析技术的元分析方法对有关儿童攻击和自我感知相关的研究结果进行分析,并对计算结果用模拟方法进行模拟。结果显示现有研究中攻击和自感认知能力之间的相关为-0．01,攻击和自我总体感知间地相关为-0．08,相关结果为低度负相关但达到显性水平,攻击和自感社交能力之间的相关关系不显,模拟结果与此类似。现有关于儿童攻击和自我感知关系的研究数量还偏少。     

汉语阅读困难儿童认知特征研究

为了解汉语阅读困难者的认知特征,本研究从９６７名５年级１１－１３岁学生中抽取了１１８名被试,将他们分成困难组（包括截点组和低成就组）和对照组,并将其在词语理解等８个认知变量上进行了比较。结果表明,图形记忆与加工能力及对词语和一般信息理解能力的缺损是汉语阅读困难者主要的认知特征。研究还表明,一般信息理解能力发展水平是区分一般阅读落后和特殊阅读落后的一个指标。     

Theoretical and methodological approaches to apparent movement of short-range process and pattern perception

A variable raster and vector display processor interfaced with a PDP-11/23 computer is briefly described. Several experiments using random-dot cinematograms (RDCs) (raster display) and line segments (vector display) are discussed. The experiments on cooperative processes of apparent movement of RDCs and spatial-frequency-filtered RDCs showed that the average cooperative neighborhood of neural interaction is about 15 min arc of visual angle. In pattern perception, based on Julesz’s texton theory (1981) and Shaw’s attention model (1980), this study showed that the aperture of attention in serial and parallel processing is a function of feature gradient, set size, and eccentricity.     

ON THE APPLICABILITY OF THE QUANTUM MEASUREMENT FORMALISM

Customary discussions of quantum measurements are unrealistic, in the sense that they do not reflect what happens in most actual measurements even under ideal circumstances. Even theories of measurement which discard the projection postulate tend to retain two unrealistic assumptions of the von Neumann theory: that a measurement consists of a single physical interaction, and that the topic of every measurement is information wholly contained in the quantum state of the object of measurement. I suggest that these unrealistic assumptions originate from an overly literal interpretation of the operator formalism of quantum mechanics. I also suggest, following Park, that some issues can be clarified by distinguishing the sense of the term 'measurement' occurring in the quantum-mechanical operator formalism, and the sense of 'measurement' that refers to actual processes of gaining information about the physical world.

Transitions in sleep problems from late adolescence to young adulthood: A longitudinal analysis of the effects of peer victimization

Adolescence is a developmental period with high vulnerability to sleep problems. However, research identifying distinct patterns and underlying determinants of sleep problems is scarce. This study investigated discrete subgroups of, changes in, and stability of sleep problems. We also examined whether peer victimization influenced sleep problem subgroups and transitions in patterns of sleep problems from late adolescence to young adulthood. Sex differences in the effects of peer victimization were also explored. In total, 1,455 male and 1,399 female adolescents from northern Taiwan participated in this longitudinal study. Latent transition analysis was used to examine changes in patterns of sleep problems and the effects of peer victimization on these changes. We identified three subgroups of sleep problems in males and two in females, and found that there was a certain level of instability in patterns of sleep problems during the study period. For both sexes, those with greater increases in peer victimization over time were more likely to change from being a good sleeper to a poor sleeper. The effects of peer victimization on baseline status of sleep problems, however, was only significant for males, with those exposed to higher levels of peer victimization more likely to be poor sleepers at baseline. Our findings reveal an important role of peer victimization in predicting transitions in patterns of sleep problems. Intervention programs aimed at decreasing peer victimization may help reduce the development and escalation of sleep problems among adolescents, especially in males.
