中文阅读中快速读者与慢速读者的词频效应

在熟练的中文阅读中,个体阅读效率越高,词汇加工效率是否越高,目前还缺少直接证据。本研究通过记录快速读者与慢速读者在阅读含有高频或低频目标词句子时的眼动轨迹来考察该问题。结果发现,在第一遍注视时间、回视路径时间和总注视时间上,快速读者对高频词与低频词的注视时间无显著差异,但都短于慢速读者;而慢速读者对低频词的注视时间显著长于高频词。即快速读者的早期词汇识别和后期词汇整合效率都较高,不受词频影响;而慢速读者的整个词汇加工效率较低,受词频影响较大。这些结果表明两组读者的词汇加工模式具有本质差异,符合个体差异性观点与词汇质量假说。

Cognitive ability,academic achievement and academic self‐concept: Extending the internal/external frame of reference model

Background. Marsh's internal/external (I/E) frame of reference model depicts the relationship between achievement and self‐concept in specific academic domains. Few efforts have been made to examine concurrent relationships among cognitive ability, achievement, and academic self‐concept (ASC) within an I/E model framework. Aim. To simultaneously examine the influences of domain‐specific cognitive ability and grades on domain self‐concept in an extended I/E model, including the indirect effect of domain‐specific cognitive ability on domain self‐concept via grades. Sample. Tenth grade respondents (628 male, 452 female) to a national adolescent survey conducted in Taiwan. Method. Respondents completed surveys designed to measure maths and verbal aptitudes. Data on Maths and Chinese class grades and self‐concepts were also collected. Results. Statistically significant and positive path coefficients were found between cognitive ability and self‐concept in the same domain (direct effect) and between these two constructs via grades (indirect effect). The cross‐domain effects of either ability or grades on ASC were negatively significant. Conclusions. Taiwanese 10th graders tend to evaluate their ASCs based on a mix of ability and achievement, with achievement as a mediator exceeding ability as a predictor. In addition, the cross‐domain effects suggest that Taiwanese students are likely to view Maths and verbal abilities and achievements as distinctly different.     

Differential recognition of pitch patterns in discrete and gliding stimuli in congenital amusia: evidence from Mandarin speakers

This study examined whether "melodic contour deafness" (insensitivity to the direction of pitch movement) in congenital amusia is associated with specific types of pitch patterns (discrete versus gliding pitches) or stimulus types (speech syllables versus complex tones). Thresholds for identification of pitch direction were obtained using discrete or gliding pitches in the syllable /ma/ or its complex tone analog, from nineteen amusics and nineteen controls, all healthy university students with Mandarin Chinese as their native language. Amusics, unlike controls, had more difficulty recognizing pitch direction in discrete than in gliding pitches, for both speech and non-speech stimuli. Also, amusic thresholds were not significantly affected by stimulus types (speech versus non-speech), whereas controls showed lower thresholds for tones than for speech. These findings help explain why amusics have greater difficulty with discrete musical pitch perception than with speech perception, in which continuously changing pitch movements are prevalent.

Role of the NO/sGC/PKG signaling pathway of hippocampal CA1 in morphine-induced reward memory

Evidence suggests that the nitric oxide (NO)/soluble guanylyl cyclase (sGC)/cGMP dependent protein kinase (PKG) signaling pathway plays a key role in memory processing, but the actual participation of this signaling cascade in the hippocampal CA1 during morphine-induced reward memory remains unknown. In this study, we investigated the role of the NO/sGC/PKG signaling pathway in the CA1 on morphine-induced reward memory using a conditioned place preference (CPP) paradigm. We found that rats receiving an intraperitoneal (i.p.) injection of 4mg/kg morphine exhibited CPP, whereas rats treated with only 0.2mg/kg morphine failed to produce CPP. Intra-CA1 injection of the neuronal NO synthase (nNOS) inhibitor 7-NI, the sGC inhibitor ODQ or the PKG inhibitor Rp-8-Br-PET-cGMPS had no effect on the acquisition of CPP by 4mg/kg morphine. Intra-CA1 injection of 7-NI blocked the consolidation of CPP induced by 4mg/kg morphine, and this amnesic effect of 7-NI was mimicked by ODQ and Rp-8-Br-PET-cGMPS. Intra-CA1 injection of the NOS substrate L-arg or the sGC activator YC-1 with an ineffective dose of morphine (0.2mg/kg, i.p.) elicited CPP. This response induced by L-arg or YC-1 was reversed by pre-microinjection of Rp-8-Br-PET-cGMPS in the CA1. These results indicated that the activation of the NO/sGC/PKG signaling pathway in the CA1 is necessary for the consolidation of morphine-related reward memory.     

空间焦虑与导航方式对寻路行为的影响

探讨了空间焦虑与导航方式对寻路行为的影响并分析了该效应的性别差异。实验被试96名,实验结果显示：在VR迷宫场景中寻路,对女性而言,空间焦虑与导航方式对寻路绩效影响显著。对空间焦虑较低的女性而言,标志导航最佳,标志与YAH地图并存时次之,YAH地图导航最差;对空间焦虑较高的女性而言,标志与YAH地图并存时效率最高,标志导航次之,YAH地图导航最差。对女性而言,YAH地图导航显著劣于其它两种导航方式。而对男性而言,空间焦虑与导航方式对寻路绩效的影响差异不显著。该研究结果可为导航支持系统的界面设计提供依据。     

The Influence of Attentional Style and Risk Perceptions on Intentions to Undergo Prophylactic Oophorectomy Among First-Degree Relatives

This study examined the predictors of women's intentions to undergo prophylactic oophorectomy. Eighty female first-degree relatives (FDRs) of ovarian cancer patients completed a measure of attentional style upon enrollment into a Family Risk Assessment Program. Following participation, measures of cancer risk perceptions, perceived benefits and costs of surgery, and intentions to undergo preventive surgery were obtained. Hierarchical regression analyses indicated that a high monitoring attentional style, as well as greater perceived risk of ovarian cancer and greater perceived benefits of the procedure, was associated with greater intentions to undergo prophylactic oophorectomy. In addition, a significant interaction between attentional style and perceived risk revealed that high monitors who felt at increased risk for ovarian cancer were less inclined to undergo surgery, whereas low monitors who perceived themselves to be at increased risk were more inclined to undergo surgery. The implications of the results for the design of counseling interventions are discussed.
