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.     

Examining a processing tradeoff explanation of proactive interference

Burns (1989) claims that proactive interference effects occur in paired-associate learning because of tradeoffs in relational and response-specific processing. Consistent with this claim, Burns demonstrated that free recall of critical-list responses is better in the interference condition than in the control condition. Burns’s processing trade off explanation predicts that the occurrence of this reverse-interference effect should be positively correlated with the occurrence of traditional interference effects. We present several experiments whose results are inconsistent with-this-prediction. We hypothesize that the reverse-interference effect is a list-length effect. The results of a final experiment, contrasting the predictions of the list-length and processing trade off explanations, support the list-length explanation.     

儿童成长型思维干预的理论基础和实践走向

思维模式是人们关于智力是否可塑的内隐信念,是个体内隐意义系统的核心和组织者。个体的思维模式可以分为成长型思维和固定型思维,其中成长型思维有利于儿童学习动机、自我效能和心理韧性的发展。早期的儿童成长型思维干预主要采用面对面的方式,近年来线上的短时程干预得到了快速发展,进而促进了干预的规模化应用,干预的内容也从内隐智力理论拓展到内隐人格理论。对干预效果的评估显示,成长型思维干预能够对儿童学业发展和社会适应产生可持续的促进作用,且对学业困难群体作用更为显著。未来的研究应重视面向对象的干预程序开发,创建有利于成长型思维发展的环境,同时应注意避免实践中的简单化偏差。     

The mediating role of cultural coping behaviours on the relationships between academic stress and positive psychosocial well‐being outcomes

While culture's effect on the coping process has long been acknowledged in the stress‐coping literature conceptually, empirical evidence and attempts to discern the specific relationship between culture and coping remain very scarce. Against this backdrop, the present study applied the Cultural Transactional Theory (Chun, Moos, & Cronkite, 2006) to examine the mediating role of cultural coping behaviours (Collective, Engagement and Avoidance Coping) on the relationship between academic stress (AS) and two positive psychosocial well‐being outcome measures: Collective Self‐esteem (CSE) and Subjective Well‐being (SWB). Responses from a sample of undergraduate students in Canada (N = 328) were analysed to test a theory‐driven, hypothesised model of coping using structural equation modelling (SEM). As hypothesised, the SEM results showed that: (a) the proposed cultural coping model fit the data well; (b) Engagement Coping and Collective Coping partially mediated the association between AS and the outcomes and (c) the path relationships among the constructs were in the hypothesised directions. A set of preliminary exploratory analyses indicated that Collective Coping was most strongly endorsed by the African/Black and the Middle Eastern cultural groups as compared to other ethnic groups. Implications of the study's findings for future research and practice concerning culture, stress, and coping are discussed.

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。
