大学生记忆的自我与专业参照效应:专业认同的作用

Self-and Major-Reference Effects on Memory in Chinese College Students: The Role of Major Identity

群体参照效应研究证实社会群体身份及内群体认同对记忆的参照加工具有重要作用。以往研究从大学生的多重社会群体身份角度探讨了内群体记忆加工优势,却忽视了其另一重要群体身份划分标准——专业。本研究结合自我和群体参照范式,设置多个参照条件(自我、专业内群体、专业外群体、语义),从专业身份这一新视角考察大学生记忆的自我与专业参照效应以及专业认同的作用,并对比个体自我与群体自我之间的差异。结果发现:(1)参照自我和专业内群体时的记忆成绩优于参照其他编码条件;(2)相比专业参照,自我参照的记忆效果更佳;(3)专业认同度越高,对专业内群体信息记忆越好。结果提示,大学生的记忆存在自我和专业参照效应,但自我参照效应更强;专业认同是专业参照效应强弱的影响因素之一。

Although a substantial body of research has supported that social identity and in-group identity play an important role in the group- reference effect （GRE） on memory, there is still a need to continue the exploration of processing characteristics of memory with reference to some other social identities （Johnson et al., 2002）. College students＇ multiple social identities, for example, schools or nationalities they belong to, were usually investigated in previous studies. However, their major identity, an effective and vital group classification criterion, was often overlooked. Besides, researchers have typically looked at SRE （The Self-Reference Effect） and GRE in a relatively isolated manner, which possibly goes against the discovery of a relationship between the self as an individual and individuals as a group （as of the same major at college） （Bennett et al., 2010）. Moreover, in-group identity has been proved to be an important influential factor of GRE. Through two experiments, combining paradigms of SR （Self-Reference） with GR （Group-Reference）, the aim of present study was to examine whether there was a self- or major-reference effect （MRE） on college students＇ memory and to compare their strengths, and then to explore the role of major identity and to contrast the differences of personal self （as an individual） and collective self （as individuals of certain major）. In Experiment 1, there were three reference conditions （self, major, semantic） with 28 Chinese undergraduates who majored in psychology as participants. All of them had no selection of minor. Each condition was assigned 20 trait words with a total of 60. In the study phase, participants were asked to determine to what extent the current word was suited to describe the referential object. For instance, ＂To what extent the word is suited to describe myself？.＂ or ＂To what extent the word is suited to describe people who major in psychology？＂ and so on. Participants needed to complete a 5-point Likert assessment by pressing the keyboard. In the recognition phase, 120 words were presented one by one, half of which had appeared in the study phase. The participants＇ task was to judge whether each word had been presented before. If it had, then they were instructed to make a ＂remember＂ or ＂know＂ response （RfK response） according to their retrieval levels. In Experiment 2, participants who majored in economics and an out-group condition were added. Accordingly, trait words in both the study and recognition phases increased to a total number of 160, and 64 Chinese undergraduates who majored in psychology and economics participated in this experiment. There were four reference conditions, namely self, ingroup, out-group and semantic. Ultimately, a questionnaire was used to measure the level of participants＇ major identity. The procedure of Experiment 2 was identical to Experiment 1. Total recognition rate, recognition rate on R response and discrimination index d＇ were the dependent variables. A one-way repeated measures analysis of variance was conducted on these three dependent variables. The results showed that, when encoded with reference to self, the words in both experiments were better remembered than in any other condition. The performance of GR encoding tasks was also better than that of the out-group condition （Experiment 1） and semantic conditions （Experiment 1 and 2）. Besides, major identity affected the memory performance with reference to in-group, rather than self, out-group, and semantic conditions. When the score of major identity was high, a better score on the memory of in-group referential words was obtained than of the out-group ones. However, when it was low, there was no difference between them. These results demonstrate that as a result of elaborative and organizational processing （Klein, 2012b）, there is a robust SRE with respect to Chinese college students＇ memory, as well as a MRE. In contrast, SRE is stronger than MRE. Furthermore, the level of college students＇ major identity might play an important role in MRE.
