【摘要】：在互联网时代,媒体多任务和社交网站使用充斥着我们的生活。当前,媒体多任务及社交网站使用对人们认知能力影响的研究结论各不相同,媒体多任务及社交网站的使用对认知能力有利还是有害,是需要进一步探讨的重要问题。本研究的目的在于考察在我国文化背景下,媒体多任务和社交网站使用对我国大学生认知能力的影响。研究使用问卷法对500名武汉市大学生的媒体多任务和社交网站使用情况进行调查,分别筛选出问卷得分在高低20%的被试,最终得到高、低媒体多任务组被试67名,高、低社交网站使用组被试60名。任务一采用2(媒体多任务经验水平：高、低)×2(色词类型：一致、不一致)混合设计,让被试进行Stroop任务,结果发现高媒体多任务组对不一致色词的反应时要短于低媒体多任务组。任务二采用单因素被试间设计,让高、低媒体多任务组完成1-back任务,结果发现在反应时上,高低媒体多任务组的主效应显著,高媒体多任务组的反应时比低媒体多任务组短。任务三采用单因素被试间设计,让高、低媒体多任务组被试完成任务转换任务,结果发现在任务转换条件下,高媒体多任务组的反应时比低媒体多任务组短。任务四采用2(社交网站使用水平：高、低)×2(词汇类型：QQ相关、QQ不相关)混合设计,对被试进行情绪Stroop测试,结果发现高社交网站使用组对QQ相关词汇的反应时要长于高社交网站使用组。任务五采用2(社交网站使用水平：高、低)×2(图片类型：QQ相关、QQ不相关)混合设计,让被试完成1-back任务,结果发现在反应时上,高低社交网站使用组主效应显著,高社交网站使用组对图片的反应时要短于低社交网站使用组。任务六采用单因素被试间设计,让高、低社交网站使用组被试完成任务转换任务,结果发现两者无显著差异。根据以上结果可以得出,媒体多任务对个体认知能力的影响表现在：能提高个体的抑制能力、工作记忆能力和任务转换能力。社交网站使用对个体认知能力的影响表现在：会引起个体对社交网站相关信息的注意偏向,提高个体的工作记忆能力。最后,文章从研究方法和设计角度反思了本研究的不足,并对今后研究的设想进行了探讨。
[Abstract]:In the age of the Internet, media multitasking and social networking use fill our lives. At present, the results of the research on the effects of media multitasking and social networking site use on people's cognitive ability are different. The use of media multitasking and social networking sites is an important issue that needs to be further explored. The purpose of this study is to investigate the effects of media multitasking and social networking site use on the cognitive ability of college students in China under the background of Chinese culture. The questionnaire was used to investigate the media multi-task and social network use of 500 college students in Wuhan. The results showed that the questionnaire scores were 20% high, and 67 subjects with low media task group were high. There were 60 participants in the low social networking site use group. Task 1 was designed in 2 (media multitasking experience level: high, low) 脳 2 (color word type: consistent, inconsistent) to allow participants to perform Stroop tasks. The results showed that the response time of high media multi task groups to inconsistent color words was shorter than that of low media multi task groups. Task 2 was designed among single factor subjects to allow high and low media task groups to complete 1-back tasks. The results showed that the main effect of high and low media multi-task groups was significant, and the response time of high and low media multi-task groups was shorter than that of low-media multi-task groups. Task 3 was designed by single factor, so that high and low media multi-task groups completed the task transition task. The results showed that the response time of high media multi-task group was shorter than that of low-media multi-task group under the condition of task transition. Task 4 used a mixed design of 2 (social networking site usage level: high, low) 脳 2 (vocabulary type: QQ related to QQ is irrelevant) to perform emotional Stroop test. The results showed that the response time of high social networking site users to QQ related words was longer than that of high social networking site use groups. Task 5 used a mixed design of 2 (social networking site usage level: high, low) 脳 2 (image type: QQ related to QQ was irrelevant), so that the subjects completed the 1-back task. The results showed that in response time, the main effect of high and low social networking site use group was significant. The response of the high-social-networking group to images was shorter than that of the low-social-networking group. Task six was designed among subjects with single factor to make the high and low social network users complete the task of task conversion. The results showed that there was no significant difference between the two groups. According to the above results, the effects of media multi-task on individual cognitive ability are as follows: it can improve individual inhibition ability, working memory ability and task switching ability. The influence of the use of social network on individual cognitive ability is that it can cause individual to pay attention to the information related to social networking site and improve the ability of working memory. Finally, the paper reflects on the deficiency of this study from the point of view of research method and design, and probes into the assumption of future research.
