初中学生类别建构中的知识效应研究

采用类别建构的实验范式,选取具有家族相似性结构的人工类别材料,考察了已有知识对初中学生类别建构的影响。实验结果表明,当类别特征能够在已有知识的基础上形成主题时,初中学生倾向于按主题建构类别,而且在主题愈突出时这种趋势愈为明显;并且,主题性质对不同领域材料的类别建构的影响是一致的。     

Worsen depression after viscosupplementation treatment for geriatric people with knee osteoarthritis?

Background/objective: Knee osteoarthritis (OA) in older people may result in psychological impairment, including anxiety and depression. This study investigates the effect of intraarticular hyaluronic acid injection (IAHA) on geriatric patients with OA. Method: A total of 102 geriatric patients with knee OA undergoing IAHA were prospectively enrolled in this study. Geriatric Depression Scale (GDS), State-Trait Anxiety Inventory (STAI), Western Ontario and McMaster University Osteoarthritis Index (WOMAC) and the International Knee Documentation Committee Subjective Knee Evaluation Form (IKDC), and Visual Analogue Scale (VAS) for pain were recorded. All outcomes were measured at baseline before injection and during two, four, and six month follow-ups. Results: IAHA had a significant short-term effect, relieving pain at the two month follow-up, but the effect was weaker at the four month follow-up. Both IKDC and WOMAC scores were significantly improved at the two month follow-up. Viscosupplementation did not improve STAI. GDS exhibited significant deterioration at the four month follow-up. Conclusions: Although IAHA for the treatment of OA provided short-term efficiency, it had no effects on anxiety and increased depression of geriatric people. Health education should be provided with caution before viscosupplementation treatment to manage expectations of the efficacy of treatment for geriatric OA patients.

Treadmill exercise enhances passive avoidance learning in rats: the role of down-regulated serotonin system in the limbic system

While serotonin (5-HT) may impair learning and memory, exercise has been reported to improve them. Whether chronic exercise can facilitate fear memory via regulating the serotonin system is unknown. We examined the effects of 4-week treadmill exercise training on levels of 5-HT and its metabolite 5-hydroxyindoleacetic acid (5-HIAA), the protein expression of its receptor 5-HT_1A and transporter in the amygdala, hippocampus and prefrontal cortex of male Sprague–Dawley rats. Our results demonstrated that treadmill exercise (1) improved the passive avoidance learning performance; (2) decreased the 5-HT level in the hippocampus; (3) decreased the expression of 5-HT_1A receptor in the amygdala without altering the transporter expression. Moreover, pretreatment with 0.1 mg/kg 8-hydroxy-di-n-propylamino tetralin, a selective 5-HT_1A receptor agonist, impaired the passive avoidance performance and completely abolished the exercise-enhanced fear memory. Our results suggest that down-regulation of the 5-HT system in the limbic system, i.e., the reduction of the hippocampus 5-HT content and the amygdala 5-HT_1A receptor expression, may be involved in the exercise-enhanced fear memory.     

The Role of Natural Class Features in the Acquisition of Phonotactic Regularities

Previous research has shown that phonotactic regularities can be acquired through recent production or auditory experience (e.g., Dell et  al., Journal of Experimental Psychology: Learning, Memory, and Cognition, 26(6), 1355–1367, 2000; Onishi et al., Cognition, 83(1), B13–B23, 2002). However, little is known about the role of phonological natural classes in this learning process. This study addressed this question by investigating the acquisition of a contingency relationship between onsets and medial glides by Mandarin speakers. The experiments involved the manipulation of three types of phonotactic regularities. In the Laryngeal version, onsets that preceded the same glide shared a voicing feature. In the Place version, onsets that preceded same glide shared a place feature. In the Neither version, onsets associated with the same glide shared neither a voicing feature nor a place feature. Results showed the Place version and the Laryngeal version were more easily acquired than the Neither version in terms of the amount of exposure needed to acquire the experimentally manipulated phonotactic schema and the sustainability of the acquired schema. The results suggest that the statistical learning mechanism that guides our processing of speech input prefers phonological regularities that follow certain natural class features. This preference may account for the way natural languages are structured phonologically. An erratum to this article can be found at

女性食物选择的演化视角：基于性选择过程的理论探讨

性选择在人类心理、行为等表型的演化过程中扮演了重要角色,但其对女性食物选择的影响却相对较少被关注。性选择塑造了男女不同的择偶策略,男性择偶时对女性外在吸引力的关注使得女性更加重视身材等外在吸引力信息。而女性身材与饮食的密切联系,进一步提示性选择过程应该会对女性的食物选择产生影响。以之为基础,梳理求偶动机激活可能引发的女性食物选择的变化,以及女性生理期不同阶段在食物选择上的变异,有助于了解性选择过程对女性食物选择的影响。未来研究中,进一步从行为、激素、脑等不同层面剖析对应影响及涉及机制,对该领域的长远发展有重要意义。
