英语学习不良儿童语音意识假词拼读与单词认知能力的关系研究 总被引:9,自引:1,他引:8
本研究探讨了英语学习不良儿童语音技能一语音意识与词汇到达的发展水平及这两项语音技能与其单词认知能力间关系。结果发现,英语学习不良儿童在假词拼读能力发展上存在缺陷.而在语音意识能力的发展方面却表现正常。在对儿童的单词认知能力进行预测时,语音意识和假词拼读能力是较好的效标。 相似文献

The human voice is one of the principal conveyers of social and affective communication. Recent neuroimaging studies have
suggested that observing pain in others activates neural representations similar to those from the first-hand experience of
pain; however, studies on pain expressions in the auditory channel are lacking. We conducted a functional magnetic resonance
imaging study to examine brain responses to emotional exclamations of others’ pain. The control condition comprised positive
(e.g., laughing) or negative (e.g., snoring) stimuli of the human voice that were not associated with pain and suffering.
Compared to these control stimuli, pain-related exclamations elicited increased activation in the superior and middle temporal
gyri, left insula, secondary somatosensory cortices, thalamus, and right cerebellum, as well as deactivation in the anterior
cingulate cortex. The left anterior insular and thalamic activations correlated significantly with the Empathic Concern subscale
of the Interpersonal Reactivity Index. Thus, the brain regions involved in hearing others’ pain are similar to those activated
in the empathic processing of visual stimuli. Additionally, the findings emphasise the modulating role of interindividual
differences in affective empathy. 相似文献

采用ERP技术并运用跨通路延迟反应范式来探讨拓扑性质知觉理论在非注意状态下是否成立,发现存在视觉MMN且视觉系统在非注意状态下对拓扑性质的加工比颜色加工更早,表明与局部属性(颜色)相比,拓扑性质在无意识中优先得到加工,拓扑性质知觉理论在非注意状态下是成立的。 相似文献

This study compared the high school academic experience of adolescents with and without childhood ADHD using data from the
Pittsburgh ADHD Longitudinal Study (PALS). Participants were 326 males with childhood ADHD and 213 demographically similar
males without ADHD who were recruited at the start of the follow-up study. Data were collected yearly from parents, teachers
and schools. The current study used assessment points at which the participants were currently in or had recently completed
grades 9, 10, 11, and 12. Results indicated that adolescents with ADHD experienced significant academic impairment in high
school relative to comparison adolescents, including lower overall and main academic subject grade point averages (GPA), lower
levels of class placement (e.g. remedial vs. honors), and higher rates of course failure. In addition, teacher reports indicated
that adolescents with ADHD completed and turned in a significantly lower percentage of assignments and were significantly
less likely to be working up to their potential. Adolescents with ADHD were also significantly more likely to be absent or
tardy during the academic year, and they were over eight times more likely than adolescents without ADHD to drop out of high
school. These findings demonstrate that children with ADHD continue to experience severe academic impairment into high school. 相似文献

大学生的经济信心与职业决策自我效能的关系—— 归因和主动性人格的调节作用 总被引:1,自引:0,他引:1
通过对513名大学三年级学生的问卷调查, 本研究探讨了全球金融危机背景下大学生经济信心对其职业决策自我效能的影响, 以及内外控制点和主动性人格对此关系的调节作用。结果表明:大学生对经济发展的信心能预测其职业决策自我效能; 内外控制点和主动性人格在此关系中, 分别都起到了调节的作用; 当两者进入同一个调节模型时, 主动性人格的调节作用掩盖了内外控制点的作用。这一调节模型丰富了职业决策自我效能的研究理论, 对高校职业生涯辅导具有借鉴意义。 相似文献

Only a few studies have examined hormones in psychopathy, and results have been mixed. It has been suggested that because hormone systems are highly interconnected, it may be important to examine multiple systems simultaneously to gain a clearer picture of how hormones work together to predispose for a certain construct. In the present study, we attempt to clarify the role of the hormones cortisol and testosterone in psychopathy by examining both hormones in a community sample of 178 adults demonstrating a wide range of psychopathy scores. Results showed that psychopathy scores were associated with an increased ratio of testosterone (baseline) to cortisol responsivity to a stressor. Psychopathy was not associated with either of these measures independently or with baseline cortisol levels. These findings suggest that these highly interconnected hormone systems may work in concert to predispose to psychopathy. 相似文献

Research based on naturalistic and checklist methods has revealed differences between English and Chinese monolingual children in their trajectories of learning nouns and verbs. However, studies based on controlled laboratory designs (e.g., Imai et al., 2008) have yielded a more mixed picture. Guided by a multidimensional view of word learning (in which different mechanisms are weighted and recruited to different extents over development), we examined English- and Mandarin-learning infants' (n = 128) ability to map novel labels to unfamiliar actions and objects. Findings reveal cross-linguistic variations in the mapping of words to actions versus objects that are consistent with those found previously with naturalistic and checklist methods. Specifically, English learners were able to map novel labels to both actions and objects at 18 months but to neither actions nor objects at 14 months. In an identical experimental paradigm, Mandarin learners at both 14 and 18 months of age were able to map novel labels to actions but not to objects. Similar patterns were found when infants were grouped based on their vocabulary size. Combined results lend support for a dynamic view of word learning that take into account multiple mechanisms interacting across developmental time with important cultural constraints. 相似文献

This study aimed to investigate the differences in brain functions during verbal working memory between individuals with alcohol use disorders (AUD) and normal controls. fMRI was used to scan brain activations associated with verbal working memory while participants performed 2-back and 0-back tasks. A total of 21 young male college students participated in the study. Eleven of those who clinically met the criteria for AUD were assigned to the AUD group, whereas ten demographically similar subjects who were social drinkers but not AUD were assigned to the normal control group. The AUD group showed less activation in bilateral frontal and precentral, left superior temporal, left superior parietal, and left cerebellar cortex during the 2-back task relative to 0-back task compared to the normal control group. In contrast, the control group showed less activation only in the right uncus than the AUD group. These results suggest that subjects with AUD present abnormality in brain functioning during verbal working memory. 相似文献
