Chinese and English speakers seem to hold different conceptions of time which may be related to the different codings of time in the two languages. Employing a sentence–picture matching task, we have investigated this linguistic relativity in Chinese–English bilinguals varying in English proficiency and found that those with high proficiency performed differently from those with low proficiency. Additional monolingual English data, reported here, showed further that high-proficiency bilinguals performed similarly to the English monolinguals, suggesting that Chinese speakers’ sensitivity to the time of an action event might be modifiable according to the extent of their experience with a tensed language.
Do English and Mandarin speakers think about time differently?Boroditsky (2001) claimed they do, but the claim did not stand in three failed replications (Chen, 2007; January & Kako
For sentences involving long-distance dependencies like relative clauses (RCs), there are two ways to view the distance between the head noun and the gap. One is the linear way and the other is the structural way. This study examines the respective roles of linear distance and structural distance and their interaction in processing long-distance dependencies in head-final RCs where the gap precedes the head noun. We measured Mandarin speakers' eye-movements on reading sentences with subject-gap RCs in pseudo-cleft constructions. Overall, the findings suggest that structural distance affects the initial stage of processing and it interacts with linear distance, and that the factor of linear distance might need to be reconsidered in the processing of gap-filler dependencies in head-final RC structures.
Purpose: This study investigated the facial processing strategies of Williams syndrome (WS) patients, who exhibit genetic deficits on chromosome 7q11.23. Because of this deficit, this clinical group has been unsuccessful in detecting configural or global information in previous behavioral studies such as the standardized block design test. However, no neurophysiological evidence has been reported regarding this impairment; thus, the event-related potentials (ERPs) technique was used to address this deficit. Methods: Female faces were manipulated (changing the features or configurations) as facial stimuli. The images used to change the features (the eyes or mouth) or configurations were based on other female faces. WS patients (n=13) and their chronological-age matched controls (n=13) participated in this study. The participants assessed the similarities or differences among consecutively presented faces from a set of models, some of which had altered features (feature-changed faces) or configurations (configuration-changed faces). The faces were randomly presented and no duplicates were displayed. Findings: Regarding response latencies and accuracy rates, the behavioral results of WS patients were similar to those of the healthy controls. Both groups demonstrated rapid detection and high accuracy rates when assessing the feature-changed faces, but responded slowly and erred considerably when assessing the configuration-changed faces. However, the groups presented distinct brainwave responses to the configuration-changed faces. The healthy controls processed the configuration-changed faces differently compared with the feature-changed faces in the vertex areas of both hemispheres, whereas the clinical group failed to differentiate these 2 types of facial stimuli. Conclusion: In this study, we discovered neural evidence for a configuration detection deficit among WS patients when processing faces. The results further identified a weak central coherence among WS patients, suggesting a syndrome-general but not syndrome-specific deficit in people with developmental disabilities. Implications: WS patients demonstrated asymmetric brain and behavioral performances during facial processing. This asymmetry was reported in a verbal study that used ERPs and a false memory paradigm. WS patients exhibit genetic deficits that cause atypical development during the early stages of life. These findings were consistent with those of our previous studies pursuing contextual competence, which is defined as the ability to integrate the meanings of words into a contextual theme by using appropriate social knowledge and semantic comprehension; this has been considered a major deficiency among those with autism or right-hemisphere brain damage. Our findings confirmed a deviant central coherence among this clinical group. Neuroconstructivists claim that a small gene mutation during the initial developmental stages can yield devastating effects in long-term development. The deficient configuration detection performance of the WS group provides evidence supporting central coherence deficiency, proving that the interaction between genes and cognition is a dynamic process.
The present study modeled the relationship between the Stroop and the neutral naming times to investigate the mechanism underlying the Stroop interference effect. 95 subjects took six alternative versions of the Stroop task and the naming times in the Stroop and neutral conditions were each averaged across the tasks to arrive at a more general measure of the Stroop and neutral naming times. Regression analysis of these general measures indicated a linear function with a small and nonsignificant intercept and a slope significantly greater than one. This finding is consistent with Chen's 1996 results and supports the hypothesis that the mechanism underlying the Stroop interference is interactive or multiplicative rather than stage-like or additive and that a ratio of Stroop over neutral naming times was psychologically a more appropriate measure.
Background and Purpose: The purposes of the study were to examine the standing balance and the role of visual information for maintaining standing balance in children with developmental coordination disorder (DCD) based on a method of meta-analysis. Methods: An extensive literature search with the key words of DCD, clumsy children, development dyspraxia, minimal brain dysfunction, and physical awkward was undergone on a number of electronic databases including Medline, PsycInfo, PubMed, and ProQuest Digital Dissertations (PQDD). To be included in this meta-analysis, a study needed to: (1) be a comparison study with a group of participants with DCD and a control group; (2) include quantitative measures of balance performance; (3) provide sufficient information to be able to calculate effect size. A correlation coefficient r-indicator was used to represent the effect size of the difference in standing balance between children with and without DCD. Results: Literature search resulted in nine studies. The effect size r of static balance and dynamic balance was 0.32 and 0.38, respectively. The effect size r of balance performance with visual input and without visual input were 0.30 and 0.35, resulting in the effect size of visual input, r=0.05. Conclusion: The results indicate that the balance performance of children with DCD was poorer than that of children without DCD and the effect size was moderate. The effect of visual input on standing balance is not different in children with DCD from children without DCD. Future studies are suggested to investigate the role of other sensory inputs or the function of sensory organization for maintaining standing balance in children with DCD.
