To increase game loyalty but decrease game addiction, this study examines online game social migration and tests the mediating effects of offline social value and maladaptive cognition on the basis of the theory of consumption value and the cognitive behavioral model of pathological Internet use. The results are as follows: (i) Overall, online game social migration is associated with greater game loyalty and less game addiction; (ii) The positive association between online game social migration and game loyalty was mediated by offline social value; and (iii) Online game social migration is associated with lower game addiction. This paper provides a new perspective (taking into account both business interests and players' psychological health) for online game research and also offers practical guidance for cooperation between game companies and the public.

This research aims to explore the impacts of ad metaphors and goal orientation on the relationship between brand commitment and attitudes toward the competitor brands. Results show that prevention‐focused consumers with high brand commitment do not exhibit differentially favorable attitudes toward the competitor brands, regardless of ad metaphors. In contrast, prevention‐focused consumers with low brand commitment exhibit more favorable attitudes toward competitor brands advocated by highly metaphorical ads than those advocated by low metaphorical ads. Moreover, promotion‐focused consumers exhibit more favorable attitudes toward competitor brands advocated by highly metaphorical ads than those advocated by low metaphorical ads, regardless of brand commitment.  相似文献

The estimation of gaze shift has been an important research area in saliency modeling. Gaze movement is a dynamic progress, yet existing estimation methods are limited to estimating scanpaths within only one saliency map, providing results with unsatisfactory accuracy. A bio-inspired method for gaze shift prediction is thus proposed. We take the effect of foveation into account in the proposed model, which plays an important role in the search for dynamic salient regions. The saccadic bias of gaze shifts and the mechanism of inhibition of return in short-term memory are also considered. Based on the probability map derived from these factors, candidates for the next fixation can be randomly generated, and the final scanpath can be acquired point by point. By the evaluation of objective measures, experimental results show that this method possesses better performance in several datasets than many existing models do.  相似文献

以547名4-6年级学生为研究对象,采用网络行为调查问卷、家庭富裕量表和青少年自我控制双系统量表,探讨儿童网络行为与学业成绩之间的关系,以及自我控制在二者之间的调节作用。结果发现:(1)儿童网络信息获取行为能够正向预测语文成绩;(2)自我控制调节网络信息获取行为与语文成绩之间的关系,同时也在儿童网络社交行为与语文成绩之间起调节作用。具体而言,自我控制中延迟满足的能力能够增强网络信息获取对语文成绩的促进作用,并且减缓网络社交行为对儿童的语文成绩的消极影响。  相似文献

Using confirmatory factor analyses, this study examined the method effects on a Chinese version of the Rosenberg Self-Esteem Scale (RSES; Rosenberg, 1965 Rosenberg, M. (1965). Society and the adolescent self-image. Princeton, NJ: Princeton University Press.[Crossref] [Google Scholar]) in a sample of migrant and urban children in China. In all, 982 children completed the RSES, and 9 models and 9 corresponding variants were specified and tested. The results indicated that the method effects are associated with both positively and negatively worded items and that Item 8 should be treated as a positively worded item. Additionally, the method effects models were invariant across migrant and urban children in China.  相似文献

The present study adopted a repetition priming paradigm to investigate the bidialectal (bilingual) representation of speakers with different native dialects by event-related potential (ERP) technique. Proficient Mandarin–Cantonese and Cantonese–Mandarin bidialectals participated in the study. They were required to judge whether a word was a biological word or not, when the words (target word) were represented under four types of repetition priming conditions: Mandarin (prime)–Mandarin (target), Mandarin (prime)–Cantonese (target), Cantonese (prime)–Cantonese (target) and Cantonese (prime)–Mandarin (target). Results of reaction time and accuracy primarily indicated larger repetition priming effects in Mandarin–Mandarin and Cantonese–Cantonese (within-language) conditions than that in Mandarin–Cantonese and Cantonese–Mandarin (between-language) conditions. But more importantly, P200 and N400 mean amplitudes revealed distinct repetition priming effects between two types of participants. Specifically, both P200 and N400 indicated that the repetition priming effect in Mandarin–Mandarin condition was larger than that in Cantonese–Cantonese condition for Mandarin–Cantonese participants, whereas it was opposite for Cantonese–Mandarin participants. In addition, P200 also suggested opposite patterns of repetition priming effects in between-language priming conditions for two groups of participants. The repetition priming effect in Mandarin–Cantonese condition was larger than that in Cantonese–Mandarin condition for Mandarin–Cantonese participants, while for Cantonese–Mandarin participants, it was opposite (Mandarin–Cantonese < Cantonese–Mandarin). The results implied a clear asymmetric representation of two dialects for proficient bidialectals. They were further discussed in light of native dialect and language use frequency.  相似文献

中小学生心理素质双因子结构的构建   总被引:1,自引:0,他引:1  
尝试构建双因子模型来验证中小学生心理素质结构的理论构想。采用整群抽样法先后两次选取被试,第一次选取重庆、四川、广东各一所小学4-6年级共1607名学生,重庆、四川、湖北、江西、浙江5个省市初一到高三共2106名中学生,第二次选取重庆市潼南区五所小学4-6年级共1334名学生、北碚区两所中学初一到高三共1057名学生,尝试构建中小学生心理素质的双因子结构,同时比较双因子模型与传统维度结构模型拟合中小学生心理素质的优劣。结果表明:相比传统维度结构模型,双因子结构模型拟合数据最优。结论:双因子模型更适用于解释中小学生心理素质的结构。  相似文献

Prior research has demonstrated the benefits (i.e., task-relevant attentional selection) and costs (i.e., task-irrelevant attentional capture) of prior knowledge on search for an individual target or multiple targets from a category. This study investigated whether the level of experience with particular categories predicts the degree of task-relevant and task-irrelevant activation of item and category representations. Adults with varying levels of dieting experience (measured via 3 subscales of Disinhibition, Restraint, Hunger; Stunkard & Messick, Journal of Psychosomatic Research, 29(1), 71–83, 1985) searched for targets defined as either a specific food item (e.g., carrots), or a category (i.e., any healthy or unhealthy food item). Apart from the target-present trials, in the target-absent “foil” trials, when searching for a specific item (e.g., carrots), irrelevant items from the target’s category (e.g., squash) were presented. The ERP (N2pc) results revealed that the activation of task-relevant representations (measured via Exemplar and Category N2pc amplitudes) did not differ based on the degree of experience. Critically, however, increased dieting experience, as revealed by lower Disinhibition scores, predicted activation of task-irrelevant representations (i.e., attentional capture of foils from the target item category). Our results suggest that increased experience with particular categories encourages the rapid activation of category representations even when category information is task irrelevant, and that the N2pc in foil trials could potentially serve as an indication of experience level in future studies on categorization.  相似文献

采用点探测实验范式,将图片按照威胁性分为高威胁性和一般威胁性,探讨焦虑程度不同的个体对不同威胁性刺激的注意特点。采用状态-特质焦虑问卷从265个大学生中选取了33名高焦虑被试和31名对照组被试。结果发现:(1)高焦虑组个体对一般威胁性刺激有显著注意偏向,对高威胁性刺激有注意回避趋势;(2)对照组个体对一般威胁性刺激没有表现出注意偏向,对高威胁刺激有注意偏向趋势。结论:(1)即使是一般威胁性图片也能引起高焦虑被试的注意偏向 (2)高威胁性图片才能引起对照组个体产生注意偏向的趋势。  相似文献

经济决策包含两个传统问题:跨期选择和风险决策。跨期选择分为冲动决策和自我控制,当冲动决策时,优先激活了与中脑多巴胺神经元相联系的旁边缘区域,包括伏隔核、眶额皮层中部和前额叶中部;自我控制即选择延迟决策时大脑双侧前额叶和后顶叶皮层神经活动增强。在风险和不确定性条件下,大脑皮层和杏仁核与风险决策联系密切。  相似文献
