本研究以技术接受模型(TAM)为理论框架, 通过对380名中学生的问卷调查考察了青少年网络游戏成瘾的影响因素及其机制。结果发现:(1)有用感、易用感、品质感知、游戏体验和态度与网络游戏成瘾显著正相关;(2)品质感知和游戏体验通过态度的部分中介作用对网络游戏成瘾产生间接影响, 同时对网络游戏成瘾有直接效应;有用感和易用感通过态度的完全中介作用对网络游戏成瘾产生间接影响, 对网络游戏成瘾没有直接效应。本研究结果表明, 品质感知、有用感、易用感和游戏体验对青少年网络游戏成瘾具有重要影响, 态度是其中的重要中介变量。 相似文献

发展性协调障碍是一种特殊的发育障碍, 它的一个显著特征是动作协调困难, 这种障碍影响着5%~8%学龄儿童的学业成绩和日常生活。发展性协调障碍常常与其他类型的学习困难并存。发展性协调障碍的病因非常复杂, 这种障碍与一定程度的视觉空间认知能力受损有关, 早期精细运动技能发育与脑神经发育进程可能存在时间的重合。近年来, 研究者们试图探索影响发展性协调障碍的神经基础, 并先后提出不同的神经关联假说。这些理论假说主要涉及到小脑、顶叶、胼胝体、基底神经节和大脑白质等脑区。本文全面回顾了该领域研究的最新进展, 并提出未来研究应该关注的方向与问题。 相似文献

鼎簋制度作为社会存在的一种反映,是一个动态的概念,把用鼎规格普遍、有序的提升归结为僭越有形而上学之嫌。春秋中期至战国中期,中原高级墓葬一般随葬数套列鼎,是鼎簋制度的套鼎时期,也是鼎簋制度的高峰期。以往多认为战国中晚期是鼎簋制度的瓦解、崩溃时期,实际上,这一时期随葬列鼎的现象仍然普遍存在,鼎簋制度并没有瓦解,其瓦解期应在秦汉。由于历史、地理等原因,山东地区的鼎簋制度与中原地区存在较大差异:一是山东多数地区没有严格推行鼎簋制度;二是山东地区鼎簋制度的基础较为薄弱,瓦解现象出现较早,瓦解速度也较快;三是春秋中晚期至战国早、中期普遍流行于中原的套鼎现象,山东地区基本没有发现。 相似文献

东汉出现了一股"矫情崇礼"的社会风气,表象背后是儒家礼制的日益渗透和"人情"的逐渐被"恶"化。面对情礼关系这个纷杂却又永恒的人生课题,"矫情崇礼"现象的出现彰显了东汉独有的时代特征。 相似文献

Psychological factors have been found to impact the pain experience and associated sexual impairment of women suffering from provoked vestibulodynia (PV). Despite a lack of randomized treatment outcome studies, particularly concerning psychological predictors of outcome, recent studies have shown that topical applications and cognitive-behavioral therapy (CBT) are among the most popular first-line interventions for PV. The present study aimed to determine the extent to which baseline fear-avoidance variables and pain self-efficacy were differentially associated with topical application and CBT outcomes at six-month follow-up. Data were obtained from 97 women who completed a randomized trial comparing these two treatments. Regression analyses revealed that for topical treatment, higher levels of baseline avoidance predicted worse pain and sexual functioning outcomes, whereas higher levels of pain self-efficacy predicted better outcomes. For CBT, higher levels of baseline fear of pain and catastrophizing contributed to higher pain intensity at follow-up, whereas higher levels of pain self-efficacy were associated with less pain. Psychological factors did not predict sexual functioning outcomes for CBT. Consistent with biopsychosocial models of pain and sexual dysfunction, results indicate that psychological factors contribute to pain and sexual impairment following treatment for PV. Specifically, findings suggest that fear-avoidance variables and pain self-efficacy are significant predictors of topical and CBT treatment outcomes in women with PV. 相似文献

Ongoing concerns exist in the literature regarding the construct of posttraumatic stress disorder (PTSD) and how to best conceptualize and measure this disorder. We compared the traditional DSM-IV PTSD symptom criteria (i.e., symptoms from clusters B, C, and D) to a revised criterion set that omits overlapping mood and other anxiety symptoms on PTSD prevalence, PTSD diagnostic caseness, associated psychiatric comorbidity, functional status, and structural validity using a cross-sectional, multi-site primary care sample of 747 veterans. After removing items theorized to overlap with mood and other anxiety disorders, PTSD prevalence was identical using both criterion sets (i.e., 12%). Overall, there were few statistically significant differences in PTSD caseness, associated psychiatric comorbidity, functional status, and structural validity across the two diagnostic criterion sets. These data provide further support that removing items that overlap with other psychiatric disorders does not significantly impact the prevalence of PTSD, its associated comorbidity and functional impairment, or its structural validity. Although the revised criterion set represents a more parsimonious model, the current study findings generally support the strong construct validity of PTSD. The implications of these study findings for research and clinical practice are discussed. 相似文献

授权风险考量与授权行为:领导-成员交换和集权度的作用 总被引:1,自引:0,他引:1
授权能够有效提升员工绩效和组织利益, 但中国企业管理者不授权现象比比皆是。本研究从授权风险的角度探讨管理者不愿授权的原因, 并检验领导-成员交换(LMX)和组织集权度的调节作用。通过17家企业收集到的157位管理者与471位下属的配对资料, HLM分析结果显示:任务绩效、组织利益风险考量与管理者授权行为负相关, 且这种负向关系还受到LMX的强化; 此外, 组织集权度在权力地位、组织利益风险考量与授权行为的负向关系中具有显著的调节作用。 相似文献

Liberation Social Psychology (la psicología social de la liberación, LSP) has developed amongst a body of psychologists in Latin America over the last decade. There has been no survey of the field in English, although some of the ideas are of relevance for those working with oppressed groups elsewhere in the world. This article explores the context in which LSP grew from the work of Ignacio Martín‐Baró and was developed by Maritza Montero, amongst others. Within LSP, key concepts emerge, including ‘conscientization’, ‘realismo‐crítico’, ‘de‐ideologization’, a social orientation, ‘the preferential option for the oppressed majorities’ and methodological eclecticism. The application of LSP is explored with reference to three domains. First, it is suggested that community social psychology as practised in some parts of Latin America reflects LSP in its emphasis on social transformation and participatory methods. Second, psycho‐social work with victims of state oppression, which adopts a highly social and societal orientation embodies LSP. Third, social analyses which explicitly adopt socio‐psychological‐political analyses of the social realities confronting countries in Latin America embrace, in different ways, principles and concepts of LSP. Some of the challenges facing LSP are discussed and open dialogue is encouraged between LSP and critical, community and applied social psychologists. Copyright © 2004 John Wiley & Sons, Ltd. 相似文献
