用两个实验考查了时距估计中刺激物的动态变化效应。结果发现,刺激物的运动、速度和旋转角度显著地影响着被试的时间判断,刺激物速度的时距延长效应对于较长时距(18s-24s)来说更加明显;运动刺激与较短、较准确的时距判断相关联;旋转角度的减少使得被试低估时距,而旋转角度的增加使得时距估计呈高估倾向。被试在时间估计过程中表现出长时距低估和短时距高估现象,本研究得到的时间估计转换点是11.4s,此点与先前的有关研究基本一致。 相似文献

Firstly, the authors analyzed the properties of primary-onditionals and secondary-conditionals, establish the minimum system
C2L
m of primary-conditionals and secondary-conditionals, and then prove some of the formal theorems of the system which have important
intuitive meanings. Secondly, the authors constructed the neighborhood semantics, prove the soundness of C2L
m, introduce a general concept of canonical model by the neighborhood semantics, and then prove the completeness of C2L
m by the canonical model. Finally, according to the technical results of the minimum system C2L
m, the authors discuss some of the important problems concerning primary-conditionals and secondary-onditionals.

探讨回指距离、干扰词的精细描述、干扰词的典型性对回指推理的影响。包括2个实验,164名大学生被试。实验1探讨干扰词精细描述类型的影响。结果表明,干扰的精细描述并非是影响回指推理的主要因素。实验2探讨干扰词和先行词的典型性类型的相对变化的影响。结果表明高典型干扰在不同回指距离条件下都会对回指推理产生影响。从而表明高典型的干扰项干扰了回指推理发生。 相似文献

Altered structural connectivity has been identified as a possible biomarker of autism spectrum disorder (ASD) risk in the developing brain. Core features of ASD include impaired social communication and early language delay. Thus, examining white matter tracts associated with language may lend further insight into early signs of ASD risk and the mechanisms that underlie language impairments associated with the disorder. Evidence of altered structural connectivity has previously been detected in 6‐month‐old infants at high familial risk for developing ASD. However, as language processing begins in utero, differences in structural connectivity between language regions may be present in the early infant brain shortly after birth. Here we investigated key white matter pathways of the dorsal language network in 6‐week‐old infants at high (HR) and low (LR) risk for ASD to identify atypicalities in structural connectivity that may predict altered developmental trajectories prior to overt language delays and the onset of ASD symptomatology. Compared to HR infants, LR infants showed higher fractional anisotropy (FA) in the left superior longitudinal fasciculus (SLF); in contrast, in the right SLF, HR infants showed higher FA than LR infants. Additionally, HR infants showed more rightward lateralization of the SLF. Across both groups, measures of FA and lateralization of these pathways at 6 weeks of age were related to later language development at 18 months of age as well as ASD symptomatology at 36 months of age. These findings indicate that early differences in the structure of language pathways may provide an early predictor of future language development and ASD risk. 相似文献
