Does social dominance generate prejudice? Integrating individual and contextual determinants of intergroup cognitions.

Social dominance orientation (SDO) has been proposed as an important variable in the explanation of prejudice. We distinguish between three conceptualizations of SDO: SDO as a personality trait (personality model), SDO as a moderator of the effects of situational variables (Person x Situation model), and SDO as a mediator of the effect of social position on prejudice (group socialization model [GSM]). Four studies (N = 1.657) looking at the relations between social positions, SDO, and prejudice in a natural setting and in a laboratory setting provide strong support for the GSM. In contrast to previous correlational findings, there is evidence of a cause (dominant social position), an effect (prejudice increases), and a mediator (SDO). These results suggest new perspectives on the integration of individual and contextual determinants of prejudice.

Improving productivity and creativity in online groups through social comparison process: New evidence for asynchronous electronic brainstorming.

This article extends the findings in synchronous room-based electronic brainstorming about the impact of social comparison process on productivity and creativity in a web-based context of asynchronous electronic brainstorming. Social comparison was manipulated with a feedback informing group members of their respective contributions on the electronic brainstorming task through a shared table regularly updated by a facilitator. In another group, although participants had the possibility to identify each contribution within the newsgroup, they did not receive any feedback in a shared table. Results showed that both group productivity and group creativity are better in the social comparison feedback condition than in the other condition. It appears that social comparison process has a positive impact on productivity and creativity in a web-based context of asynchronous electronic brainstorming, but only when participants have access to a shared table facilitating the comparison among group members. This finding provides some useful recommendations for learning facilitators to improve productivity and creativity in the context of computer-supported collaborative learning over the Internet. It also invites to future innovative technological developments to improve participation in online groups.

Social Identity, Group Processes, and Performance in Synchronous Computer-Mediated Communication.

This study examined group processes in a synchronous context and their effects on performance, assuming that these processes would be strongly dependent on the salience of social identity. It was predicted that the mere categorization of students into an online group and comparison with other groups, 2 basic conditions related to social identity, would enhance group identification, interaction patterns, and group performance in a relatively complex academic task. As predicted, the categorization manipulation enhanced group identification and increased task- and morale-building communication. It was not related to performance. These findings invite a more thorough examination of the impact of social identity on the building of a sense of online community at the early stage of a learning process.

Social dominance orientation, prejudice, and discrimination: A new computer-based method for studying discriminatory behaviors

A number of studies have shown that the scale of social dominance orientation (SDO), used to measure the degree of preference for inequality among social groups, is a predictive measure of social and political attitudes toward stigmatized outgroups. However, the relationship between SDO and discrimination has received little attention. The main goal of this study was to assess the validity of a new computer-based method used to measure discriminatory behaviors in a laboratory setting. An additional goal was to test the mediating role of prejudice in the relation between SDO and discrimination. The results provide a first validation of this new method and demonstrate that the effect of SDO on discrimination is mediated by prejudice.

Social Comparison Orientation Moderates the Effects of Group Membership on the Similarity-Attraction Relationship

ABSTRACT The present study examined how the similarity-attraction relationship is affected by a combination of the tendency to compare oneself to other people (Social Comparison Orientation, SCO) and group membership. We expected that high-SCO individuals would prefer similar to dissimilar others only when the target belonged to their in-group and was relevant for the evaluation of their self-concept. It was also expected that among low-SCO individuals who are more certain about the self and less concerned about “being evaluated,” a main effect of attitude similarity would appear, regardless of the group membership of the target. Results partially support these predictions and suggest that further research should be carried out into the combined effects of individual and group variables in the attraction literature.

Effects of Stereoscopic Display on Learning and User Experience in an Educational Virtual Environment

ABSTRACT Over the past decade, many studies have examined the potential benefits of educational virtual environments (EVEs), either by comparing them with other media or by assessing the effects of their features on learning. Paradoxically, very few of them have explored the effects of stereoscopic versus nonstereoscopic displays on learning and/or the subjective experience provided in an EVE. Our study was designed to fill this gap, by comparing the effects of these two virtual reality modes in an interactive mechanics learning task. We collected measures of task effectiveness (success/failure and completion time), learning outcomes and subjective experience (user experience, flow, and immersion). Results showed that (1) users were more successful in the learning tasks in the stereoscopic condition, and (2) perceived affective quality, flow, and immersion were better in this condition.

Comparing the effectiveness of peer instruction to individual learning during a chromatography course

Peer instruction has been recognized as an instructional method having a positive impact on learning compared to traditional lectures in science. This method has been widely supported by the socio-constructivist approach to learning giving a positive role to interaction between peers in the construction of knowledge. As far as we know, no study has been conducted from the socio-cognitive approach which suggests that individuals working alone perform better than those interacting with others in groups. Thus, the aim of the present study was to examine whether peer instruction improves learning when compared with an individual learning method that does not require any interaction with peers. After being randomly divided into either a peer instruction or an individual learning condition in a chromatography course, students had to answer to a series of multiple-choice questions using clickers at the beginning (pre-test) and end of (post-test) the session. Results revealed that the percentage of correct answers increased similarly from the pre- to the post-test in both conditions. Nevertheless, students perceived the peer instruction method as being more satisfying, engaging and useful than the individual learning method. The findings revealed that peer instruction provides subjective benefits, but failed to demonstrate a greater learning gain.

A step further in Peer Instruction: Using the Stepladder technique to improve learning

Peer Instruction (PI) is an instructional strategy for engaging students during class through a structured questioning process that improves the learning of the concepts of fundamental sciences. Although all students are supposedly engaged in discussions with their peers during Peer Instruction, the learning gains generally remain at a medium level, suggesting a lack of participation of certain students who do not benefit from social interactions. The present study examined whether the Stepladder technique might optimize the Peer Instruction method and increase learning gains. With this technique, students enter a group sequentially, forcing every group member to participate in discussions. Eighty-four chemistry students were asked to answer easy and difficult multiple-choice questions before and after being randomly assigned to one of three instructional conditions during a chromatography lesson (Classic PI vs. Stepladder PI vs. Individual Instruction without any discussion with peers). As predicted, results showed that learning gains were greatest in the Stepladder PI group, and that this effect was mainly observed for difficult questions. Results also revealed higher perceived satisfaction when students had to discuss the questions with their peers than when they were not given this possibility. By extending the Stepladder technique to higher education, these findings offer a step forward in the Peer Instruction literature, showing how it can enhance learning gains.

Study of some determinants of social comparison strategies using a new methodological tool: towards a dynamic approach

In addition to proposing a new method for testing the variability of social comparison strategies, this study looks at whether and how the social value of the comparison dimensions affect those strategies. After being attributed a superior, neutral, or inferior position on a dimension with a high or low social value, subjects were told they had to select 10 persons in order to choose a working partner among 30 comparison targets. Two pieces of information (a performance and a personality trait) presented in a table on a computer screen were given as a basis for the choice. The results showed that the social value of the dimension was an important determinant of the social comparison strategies, and that variability of these strategies appeared only when inferiority was experienced on a socially-valued dimension. While pointing out the relevance of the method employed, the results suggest the merits of taking the social value of comparison dimensions into account, and of studying social comparison process from a dynamic rather than static point of view.

Social gaming is inSIDE

The present experiment aimed to determine how quiz performance in a team game-based learning environment can be predicted from the Social Identity model of Deindividuation Effects (SIDE). According to this model, anonymity influences social behavior by accentuating the salience of group identity and reducing interpersonal differences, leading to greater group identification and motivation to work for ones own group. As these effects could lead to higher cognitive performance, the goal of the present research was to extend predictions based on the SIDE model on performance in online game-based learning environments. After measuring their prior computing knowledge, 343 Master Degree students were placed in virtual teams on a trivial criterion to perform a series of online quizzes about computing and the Internet. An anonymous (or individuated) username was attributed to each team member to connect to the online learning environment, and information about comparison between teams was used to manipulate the degree of salience of group identity (high versus low). As predicted by the SIDE model, anonymity boosted performance when group identity was salient, but only for students with low prior knowledge. Unexpectedly, it was also found that anonymity boosted the performance of students with high prior knowledge when group identity was not salient. A similar pattern was found for perceived mastery of computing and the Internet. Theoretical and practical implications of the SIDE model are discussed, and specifically its application to social gaming to optimize online learning. The SIDE model predicts that anonymity influences social behavior by accentuating the salience of group identity.Predictions are extended to quiz performance in a team game-based learning environment.As predicted, anonymity boosts performance of low prior knowledge students when group identity is salient.The same positive effect is observed among high prior knowledge students when group identity is not salient.Applying the SIDE model to social gaming is a useful strategy to optimize online learning.
