Developmental changes associated with cross-language similarity in bilingual children

The main goal of the present study was to investigate how the degree of orthographic overlap between translation equivalents influences bilingual word recognition processes at different stages of reading development. Spanish–Basque bilingual children with ages ranging from 8 to 15 years were tested in an explicit translation recognition task with a large set of items. Critically, the degree of cross-language similarity (i.e. the cognate status) between the references and the correct targets was manipulated along a continuum in order to investigate how the reliance on cross-language orthographic overlap varies as a function of reading experience. Results showed that younger children were significantly more sensitive to the cognate status of words than older children while recognising translation equivalents, and that this difference did not depend on the speed of response of the participants. These results demonstrate that the influence of cross-language similarity progressively diminishes as a function of increased exposure to print together with the maturation of the mechanisms responsible for language interference suppression, as suggested by developmental models of bilingual lexical access.     

词素的结构对称效应:结构对称汉语成语认知特点的进一步研究

运用词素启动作业,进一步考察了结构对称性汉语成语的识别过程.结果发现(1)无论是用成语的前二个字还是后二个字启动,在成语识别过程中都存在明显的词素结构对称效应,即结构对称成语中的词素启动效应明显大于非对称成语中的词素启动效应.(2)成语的结构对称性、熟悉度和启动词素位置之间存在显著的三阶相互作用.简单效应的分析表明无论成语前二个字还是后二个字启动,词素的结构对称效应均只在低熟悉度成语的识别过程中显著;在前二个字启动时,非对称成语的识别还存在熟悉度效应.

说普通话儿童的语音习得

以说普通话的１２９名一岁半至四岁半儿童的口语资料为基础,首次确定了正常发展的普通话儿童在语音习得过程中各年龄段的音位集合、音位习得的先后顺序、及习得过程中典型的语音简化类型。研究结果可以应用到普通话儿童语音发展水平标准化测试,及对患有语音障碍的儿童的诊断。此外,研究结果还表明在普通话儿童的语音习得中同时体现了各语言共有的“普遍趋势”和普通话独有的语音特征,从而为跨语言语音习得的研究提供了新的证据,进一步发展了儿童语音习得的理论。     

百善孝为先?大学生双元孝道信念与网络成瘾的关系研究

本研究基于双元孝道模型和病理性互联网使用的认知行为模型,考察双元孝道信念对网络成瘾的影响,并检验非适应性认知的中介作用。以1152名大学生为被试,采用双元孝道信念量表、非适应性认知量表和网络成瘾量表进行测试,结果发现：（1）互惠性孝道和非适应性认知显著负相关,和网络成瘾显著负相关;权威性孝道和非适应性认知显著正相关,和网络成瘾显著正相关;非适应性认知和网络成瘾显著正相关;（2）非适应性认知在孝道信念与网络成瘾之间起中介作用。具体而言,互惠性孝道负向影响非适应性认知,权威性孝道正向影响非适应性认知,非适应性认知正向影响网络成瘾。本研究的结果表明,根植于中国传统文化的孝道信念通过非适应性认知的中介作用影响网络成瘾;而且互惠性孝道和权威性孝道具有相反的作用。     

时间洞察力对成瘾行为的影响及其机制

成瘾行为给个体和社会带来了严重的危害。对成瘾人群时间洞察力的研究成为探讨成瘾行为产生和发展的一个新的视角。过去消极、现在享乐和现在宿命时间洞察力取向的个体更可能出现成瘾行为, 而未来时间洞察力取向则是成瘾行为的一个保护性因素, 它不仅可以减少成瘾行为的发生, 也有利于成瘾行为的康复。从自我调节, 冲动性决策等行为机制和前额叶的神经机制方面可以帮助我们深入理解时间洞察力对成瘾行为的影响。未来研究可以进一步探讨不同成瘾行为者时间洞察力的一致性与特异性; 采用纵向研究方法探讨成瘾者时间洞察力的动态变化过程; 对成瘾者的洞察力进行干预, 增加成瘾者的未来时间洞察力, 减少其过去消极和现在时间洞察力取向来帮助成瘾者实现时间洞察力的平衡, 从而提高其戒断效果。     

Using intraverbal prompts to increase divergent intraverbal responses by a child with autism

We examined the effectiveness of intraverbal prompts to increase the number of divergent responses to categorical questions composed of compound stimuli (e.g., Name some red things) for a 6‐year‐old child with autism. The intraverbal prompts involved providing the function, feature, and class of the target responses. A multiple probe across behaviors design was used. Results indicated that the child's total number of divergent responses was increased and maintained during 2‐week follow‐up probe trials. Novel responses were observed across conditions.     

Welcome to “the Rock”: Service Providers’ Views on Newcomer Youth Integration in Newfoundland and Labrador

This study investigates the needs of newcomer youth in Newfoundland and Labrador, and the services provided to them in the provincial capital, St. John’s, through the lens of service providers. We employ Bronfenbrenner’s bioecological model (1999, 2005) as the conceptual framework to explore how various ecological systems interact with one another to influence the development of newcomer youth. Data were drawn from 33 semi-structured interviews with personnel in various immigrant and refugee support agencies, medical and counseling units, municipal recreational offices, and educational programs, as well as ten observations of their programs. Our findings indicate that the current services and programs provide effective support in a number of areas. However, closer collaboration can be established between schools and community organizations, among different service agencies, and involving the business community. Service gaps identified include a lack of transportation to and from school, insufficient academic bridging programs, and no career counseling catering to newcomer students. We argue that service agencies should consider shifting some of their programs to the newcomer youth’s microsystems of school and family, and that the provincial educational authorities need to look into the transportation issue that infringes upon the rights of these students to appropriate school instruction.     

Perfectionism mediated the relationship between brain structure variation and negative emotion in a nonclinical sample

In maladaptive respects, perfectionism reflects an individual’s concern over making mistakes and doubting the quality of his or her own actions excessively, which would affect one’s emotion. However, little is known about the neural mechanisms associated with the perfectionism and negative affect. In this study, voxel-based morphometry was performed to identify the brain regions underlying individual differences in perfectionism, which was measured by the Chinese Frost Multidimensional Perfectionism Scale (CFMPS), in a large sample of nonclinical young adults. Our results showed that the two subdimensions of the perfectionism, concern over mistakes (CM) and doubts about actions (DA), were both positively correlated with the self-reported anxiety and depression as well as the gray matter volume (GMV) in the anterior cingulate cortex (ACC), a pivotal brain region in cognitive control, affective state, and regulation. Moreover, CM, DA, and organization scores were respectively correlated with distributed brain regions involved in multiple cognitive and emotion processes. Our results furthermore revealed that the score of DA acted a mediational mechanism underlying the relationship between the GMV of ACC and self-rating negative affect (anxiety and depression). Taken together, these results might suggest the neuroanatomical basis of perfectionism and the association among the perfectionism, negative emotion, and brain architecture. This study emphasized that perfectionism could play a crucial role in the arousal of negative affect.     

奖赏对海洛因成瘾者执行功能的影响机制

一些研究发现海洛因成瘾者奖赏失调表现为:对海洛因相关线索的注意偏向、渴求感增加,对金钱奖赏表现出"即时收益优先"的高风险决策模式和对长时收益的敏感性降低。另一些研究发现海洛因成瘾者的执行功能存在障碍。奖赏失调和执行功能障碍在成瘾物质使用的维持和复吸中起着重要作用。双重竞争模型认为奖赏和执行功能的交互作用决定着行为的结果,但是奖赏对海洛因成瘾者执行功能的影响机制还不清楚。因此,拟使用事件相关电位技术来考察海洛因相关线索和金钱奖赏对不同戒断期成瘾者执行功能的影响机制,短期(1~3个月)、长期(18个月以上)海洛因戒断者和健康对照组被比较。这不仅有助于构建完善的成瘾理论体系,还有助于确定临床戒断后复吸的风险因素和不同戒断期的治疗目标。
