中国香港双语儿童初步阅读能力与语音、文字加工关系的研究

采用音节检测、短时言语记忆、快速命名等语音加工任务和汉字、字母、数字等方向加工任务,探讨语音和文字加工在儿童初步阅读中的作用,116名6岁左右的香港双语儿童参加了测试。结果表明：语音加工能力是跨语言的比较稳定的因素,是预测汉语和英语阅读的较好指标;文字加工具有特异性．即汉字方向加工只能预测汉语阅读,字母方向加工则预测英语阅读。     

Genetic and environmental influences on individual differences in printed word recognition

The genetic and environmental etiologies of individual differences in printed word recognition and related skills were explored in 440 identical and fraternal twin pairs between 8 and 18 years of age. A theoretically driven measurement model identified five latent variables: IQ, phoneme awareness, word recognition, phonological decoding, and orthographic coding. Cholesky decomposition models on these five latent constructs revealed the existence of both common and independent genetic effects, as well as non-shared environmental influences. There was evidence for moderate genetic influences common between IQ, phoneme awareness, and word-reading skills, and for stronger IQ-independent genetic influences that were common between phoneme awareness and word-reading skills, particularly phonological decoding. Phonological and orthographic coding skills in word recognition had both significant common and significant independent genetic influences, with implications for "dual-route" and "connectionist" reading models, subtypes of reading disabilities, and the remediation of reading disabilities.     

Perceived structure from optic flow: consistent versus variable mapping of 3-D Euclidean structure

In an earlier study (Börjesson & Lind, 1996), the perception of Euclidean structure from polar projected two‐frame apparent motion sequences was studied. The results showed that Euclidean structure is not perceived. However, at larger visual angles a certain consistency in the mapping between distal and perceived structure exists. The aim of the present study was to more precisely examine how this degree of consistency varies as a function of visual angle. In Experiments 1 and 2, slant judgments of simulated and real planes indicated that the degree of consistency is a positive function of visual angle. No definite sign of a Euclidean mapping could, however, be found even in the full view condition. Experiment 3 examined texture gradients and the response method used. The results showed that texture gradients did not influence the degree of consistency of the mapping between distal and judged depth and that the response method was both reliable and valid. However, texture gradients did influence the absolute values of the slant judgments. The role of Euclidean and affine mappings of distal structure is discussed and it is proposed that the perceptually important distinction is not between affine and Euclidean mapping, but rather between two types of affine mappings—consistent and variable.     

Therapists’ self-reported chronic strategies of disconnection in everyday life and in counselling and psychotherapy: an exploratory study

The aim of this study was to explore how therapists believe they may relationally disconnect from other people and their clients, with an overall objective of developing methods for enhancing relational depth in counselling and psychotherapy. Participants were 168 trainee and practicing therapists, who listed their chronic strategies of disconnections (CSoDs) in everyday relationships, and then rated the presence of these CSoDs in their therapeutic work. Thirty-nine categories of self-reported everyday CSoDs emerged, organised into seven domains. Most prevalent were behavioural, passive and intrapsychic strategies. Over half of the CSoDs were rated as being present in therapy to a minimal extent, most commonly passive CSoDs, disingenuous CSoDs and humour. Male therapists, and trainee therapists, were most likely to identify their CSoDs as present in therapy.     

拼音输入法经验对汉字字形和语音加工的影响

随着电脑的广泛应用, 电脑打字已经成为人们日常生活中不可或缺的一部分。对于汉语使用者而言, 电脑打字完全不同于传统的书写方式, 构成了一种全新的语言使用经验。这种新的经验是否影响汉字加工值得探讨。通过两个实验分别考察了电脑打字对汉字语音和字形加工的影响。实验一的结果表明, 拼音输入法经验对声母和韵母的加工都有促进作用; 实验二的结果表明, 拼音输入法经验对成字部件和非成字部件的加工也有促进作用, 而且对成字部件搜索的促进作用显著大于非成字部件。     

Infants’ responsiveness to pictorial depth cues in preferential-reaching studies: A meta-analysis

The findings of numerous preferential-reaching studies suggest that infants first respond to pictorial depth cues between 5 and 7 months of age. However, three recent preferential-reaching studies have found evidence of responsiveness to pictorial depth cues in 5-month-olds. We investigated these apparently contradictory results by conducting meta-analyses of the data from 5-month-olds who participated in preferential-reaching studies. The data from 16 samples, comprising 475 infants 5–5.5 months of age, were integrated. The results showed that the infants responded more consistently to depth relationships specified by pictorial cues under monocular than under binocular viewing conditions (p < .001), indicating that 5-month-old infants respond to pictorial depth cues. This effect remained significant (p < .001) when the individual experiments that had found significant results were omitted from the analysis. Although the majority of experiments were unable to find evidence of pictorial depth perception individually, this ability was clearly revealed when their results were combined.     

中文阅读中的字形与语音加工

该文报告两个探讨字形及语音加要于中文阅读中所起之作用的实验。基本实验作业是让被移动鼠标以阅读计算机屏幕逐字呈现之短文。计算机记录文中个别单字中呈现时间作为反映阅读理解即时加工的因变量。在每篇文章中段都有一关键字,用来观察在此字位置出现原字、同音字、形似字或无关字对阅读所造成的影响。结果发现,在阅读初期,同音字、形似字及无关字所造成的干扰效应,无论在效果大小及出现位置上并无差异。别外,干扰效应在同音     

Internalization as the Change Process

Abstract

The process of change can be understood from a variety of perspectives. Using the case of a self-mutilating woman whose educational, social, and psychological impairments resulted from years of childhood abuse and neglect, this article demonstrates an object relational perspective whereby internalized “bad” self and object representations are modified and replaced by more benign internalizations. Additionally, a wide variety of techniques are suggested and illustrated, including those that represent our strong social work training coupled with interventions that are more usually associated with psychodynamic psychotherapy.     

The representation and perception of 3D space: Interactions between 2D location and depth

ABSTRACT

We live in a 3D world, and yet the majority of vision research is restricted to 2D phenomena, with depth research typically treated as a separate field. Here we ask whether 2D spatial information and depth information interact to form neural representations of 3D space, and if so, what are the perceptual implications? Using fMRI and behavioural methods, we reveal that human visual cortex gradually transitions from 2D to 3D spatial representations, with depth information emerging later along the visual hierarchy, and demonstrate that 2D location holds a fundamentally special place in early visual processing.
