汉字词识别过程的形,音,义编码作用的研究 总被引:7,自引:0,他引:7
本文通过两个实验,采用汉字词形、音、义特征匹配任务,探讨了影响汉字词的形、音、义编码与提取方式的有关因素。实验一发现在速示条件下,对汉字词再认的成绩并不受字词的使用度的影响,反应时无明显变化,而主要受编码加工的深度影响。在形、音、义特征加工中,对音码的加工时间最长,再认的正确率最低;义码的加工时间较短,再认正确率最高;形码的反应时及再认成绩介于音码与义码之间。实验二在非速示条件下也获得了相同的结果。研究结果表明,在汉字词的形、音、义特征中,存在着编码加工深度的差异。 相似文献

Viewed from the center of projection, a perspective picture presents the pictorial depth information of a scene. Knowing the center of projection, one can reconstruct the depicted scene. Assuming another viewpoint is the center of projection will cause one to reconstruct a transformed scene. Despite these transformations, we appreciate pictures from other viewpoints. The compensation hypothesis states that the visible picture surface allows observers to compensate for transformations by locating the center of projection and experiencing pictorial space from there. We show that observers neither completely compensate for nor experience transformations of space as geometry would predict. We propose a modified compensation hypothesis according to which different degrees of visibility of the picture surface invoke different degrees of compensation. 相似文献

There is a common-sense view of language, which is held by Wittgenstein, Strawson Dummett, Searle, Putnam, Lewis, Wiggins,
and others. According to this view a language consists of conventions, it is rule-governed, rules are conventionalised, a
language is learnt, there are general learning mechanisms in the brain, and so on. I shall call this view the ‘ordinary language’
view of language. Chomsky’s attitude towards this view of language has been rather negative, and his rejection of it is a
major motivation for the development of his own theory. In this paper I shall review Chomsky’s long-standing criticisms. I
shall show that (1)Chomsky’s argument does not constitute a dismissal of the ‘ordinarylanguage’ view of language, (2) Chomsky’s
conclusions about language do not follow from his argument, and (3) the ‘ordinary language’ view actually points to a promising
way for us to understand the true nature of language and mind.

We investigated relationships between Chinese children's imaginary companions (ICs) and peer relationships and social competence in 160 children, aged 5–6 years old. Children and their mothers participated in the interviews regarding the details of the children's ICs, including the type of the companion and the quality of the child–IC relationship. Peer relationships were assessed using sociometric nomination and perceived popularity nomination. Teachers rated children's social competence. Here, 55 children (34.3%) were deemed to have engaged in imaginary companion play. There was no relationship between imaginary companion types and child–IC relationship qualities. Children with invisible friends received more positive nominations than children with personified objects. Children with egalitarian relationships received more positive nominations and popularity nominations, but fewer negative nominations and unpopularity nominations than children with hierarchical relationships. Compared with children with hierarchical relationships, teachers rated the children with egalitarian relationships higher in social competence. The results suggest that imaginary companion types and relationship qualities may represent different dimensions of imaginary companions, calling attentions to the different mechanisms underlying imaginary companion types and relationship qualities with respect to social functioning. 相似文献

The Ability of Face Viewpoint Transformation Remains Immature at Age of 12: Evidence from Recognition of Faces with Different Familiarity in Children

Children are immature in face recognition, particularly in face configural decoding. This study examines the developmental difference of face recognition in another mechanism: viewpoint transformation processing. Adults and sixth‐grade children were instructed to match a series of one‐tone black face silhouettes to their corresponding front‐view faces. This task involves sophisticated calculation in pictorial information, precise viewpoint transformation, and most probably a 3‐D face representation. The results showed that although the performances were well above chance level in the recognition of familiar faces, for children, they were at chance level in the recognition of unfamiliar faces. The results indicate that children, at least to the age of about 12 years, are still immature in the processing of face viewpoint transformation compared to adults. 相似文献

This study examined (1) the relative prevalence of childhood abuse and other pathological childhood experiences in China reported by outpatients with borderline personality disorder (BPD), with other personality disorders, and without personality disorders; and, (2) whether the primary predictors of BPD in North America are associated with the development of BPD in China. The childhood experiences of 203 outpatients with BPD, 109 outpatients with other personality disorders, and 70 outpatients without Axis II diagnoses were assessed with the Chinese version of the Childhood Experience of Care and Abuse Questionnaire (CECA.Q). Patients with BPD reported significantly more physical, emotional, and sexual abuse than either comparison group. Four types of childhood experiences were significant predictors of BPD: maternal neglect, paternal antipathy, sexual abuse, and maternal physical abuse. The findings suggest that maternal physical abuse is as strong a predictor of BPD in China as sexual abuse, a finding not replicated in North America. 相似文献

Several studies have demonstrated age-related declines in general executive function and memory. In this study, we examined cross-sectional and longitudinal age effects in more specific cognitive processes that constitute executive function and memory. We postulated that, whereas some components of executive and memory functions would show age differences and longitudinal declines, other specific abilities would be maintained or even improve with repeated testing. In a sample of individuals ≥55 years old from the Baltimore Longitudinal Study of Aging, we found longitudinal declines in inhibition, manipulation, semantic retrieval, phonological retrieval, switching, and long-term memory over a maximum of 14 years follow-up. In contrast, abstraction, capacity, chunking, discrimination, and short-term memory were maintained or even improved longitudinally, probably due in part to repeated testing. Moreover, whereas several different abilities were correlated across participants' cross-sectional performance, longitudinal changes in performance showed more heterogeneous trajectories. Finally, compared with cross-sectional performance, longitudinal trajectories showed better distinction between participants with and those without later cognitive impairment. These results show that longitudinal cognitive aging of executive and memory functions is not a uniform process but a heterogeneous one and suggest that certain executive and memory functions remain stable despite age-related declines in other component processes.

Eight studies with data from 2316 students are presented describing the development and preliminary validation of the Physical
Appearance Perfectionism Scale (PAPS), a brief measure with two subscales: Worry About Imperfection and Hope For Perfection.
Results from exploratory and confirmatory factor analyses confirmed the measure’s two-dimensional structure. Moreover, correlation
analyses provided first evidence for the two subscales’ differential validity: Worry About Imperfection showed negative correlations
with positive self-perceptions of one’s appearance (e.g., appearance self-esteem) and positive correlations with maladaptive
concerns aspects of perfectionism, physical appearance concerns (e.g., body image disturbances), and body weight control whereas
Hope For Perfection showed positive correlations with positive striving aspects of perfectionism, positive self-perceptions,
and impression management. In addition, all PAPS scores showed high reliability (Cronbach’s alpha) and temporal stability
(test-retest). Overall the findings suggest that the PAPS is a reliable and valid instrument to assess positive and negative
aspects of physical appearance perfectionism. 相似文献

Do false memories last? And do they last as long as true ones? This study investigated whether experimentally created false memories would persist for an extended period (one and a half years). A large number of subjects (N = 342) participated in a standard three‐stage misinformation procedure (saw the event slides, read the narrations with misinformation, and then took the memory tests). The initial tests showed that misinformation led to a significant amount of false memory. One and a half years later, the participants were tested again. About half of the misinformation false memory persisted, which was the same rate as for true memory. These results strongly suggest that brief exposure to misinformation can lead to long‐term false memory and that the strength of memory trace was similar for true and false memories.
