Laptop usage affects abstract reasoning of children in the developing world

There is a rising trend to provide low-cost laptops to children in developing countries. Notwithstanding strong claims about the educational effectiveness of these programs, there is very little systematic evidence. Given the level of modernization and the teacher-led learning environment in developing countries, the usage of laptops in such contexts may affect children in ways that are quite different to how they would affect children in developed countries. A field experiment was conducted to compare abstract reasoning of Ethiopian children equipped with a laptop (n = 203) with a matched control group (n = 210) after 6 months of usage. Children with a laptop had significantly higher scores on finding analogies and categories. Effects were significant among children in grade 6 and 7, but not in grade 5. Different laptop activities may boost childrens abstract reasoning. Theoretical and practical implications and the implemention of laptops in developing countries are discussed.

An assessment of positive illusions of the physical attractiveness of romantic partners

Positive illusions about a partner’s physical attractiveness occur when individuals’ ratings of their partner’s attractiveness are more positive than more objective ratings. Ratings that may serve as a’’reality benchmark’ include ratings by the partner him/herself and observer ratings. The present study compared the effects of using different reality benchmarks on the strength of positive partner physical attractiveness illusions (n = 70 couples). Results showed that individuals positively biased both their own and their partner’s physical attractiveness. As a consequence, using a partner’s self-ratings as a reality benchmark results in an underestimation of positive illusions. Presenting participants with photographs had a small effect on physical attractiveness ratings provided by women, showing that photographs, to some extent, might constrain positive illusions.

Resounding Silences : Subtle Norm Regulation in Everyday Interactions

In this article we suggest a mechanism for norm regulation that does not rely on explicit information exchange or costly reinforcement, but rather on the sensitivity of group members to social cues in their environment. We examine whether brief conversational silences can (a) signal a threat to one’s inclusionary status in the group and (b) motivate people to shift their attitudes to be in line with group norms. In two experiments—using videotaped and actual conversations, respectively—we manipulated the presence of a brief silence after group members expressed a certain attitude. As predicted, attitudes changed relative to the norm after such a brief silence. Those highly motivated to belong changed their attitude to become more normative, whereas those less motivated to belong shifted away from the group norm. The results suggest that social regulation may occur through very subtle means.

If They Were to Vote, They Would Vote for Us

In two field studies, we examined whether voters overestimate support for their political party among nonvoters. In Study 1, voters estimated the percentage of votes their party would receive in an upcoming election, and this percentage increased when voters estimated the percentage of votes their party would receive if nonvoters also were to vote. In Study 2, participants overestimated support for their party even when we made them explicitly aware of current levels of this support by presenting them with poll-based forecasts of election results. Furthermore, Study 2 demonstrated that commitment to vote for a specific party predicted the degree of overestimation. Our results imply that highly committed voters are particularly likely to project support for their party onto nonvoters. Implications for the literature on social projection and social identity are discussed.

Uniform and Complementary Social Interaction: Distinct Pathways to Solidarity.

We examine how different forms of co-action give rise to feelings of solidarity. We propose that (a) coordinated action elicits a sense of solidarity, and (b) the process through which such solidarity emerges differs for different forms of co-action. We suggest that whether solidarity within groups emerges from uniform action (e.g. synchronizing, as when people speak in unison) or from more complementary forms of action (e.g. alternating, when speaking in turns) has important consequences for the emergent position of individuals within the group. Uniform action relies on commonality, leaving little scope for individuality. In complementary action each individual makes a distinctive contribution to the group, thereby increasing a sense of personal value to the group, which should contribute to the emergence of solidarity. The predictions receive support from five studies, in which we study groups in laboratory and field settings. Results show that both complementary and uniform co-action increase a sense of solidarity compared to control conditions. However, in the complementary action condition, but not in the uniform action (or synchrony) condition, the effect on feelings of solidarity is mediated by a sense of personal value to the group.

Beyond Content of Conversation The Role of Conversational Form in the Emergence and Regulation of Social Structure

Social interaction is pivotal to the formation of social relationships and groups. Much is known about the importance of interaction content (e.g., the transfer of information). The present review concentrates on the influence of the act of conversing on the emergence of a sense of solidarity, more or less independently of the content. Micro-characteristics of the conversation (e.g., brief silences, smooth turn-taking) can profoundly influence the emergence and the regulation of relationships and of solidarity. We suggest that this might be because the form of a conversation is experienced as an expression of the social structures within the group. Because of its dynamic nature, moreover, the form of conversation provides group members with a continuous gauge of the group’s structural features (e.g., its hierarchy, social norms, and shared reality). Therefore, minor changes in the form and flow of group conversation can have considerable consequences for the regulation of social structure.

“More Than Words”: Social Validation in Close Relationships

Conversations are susceptible to many disturbances: A speaker’s hesitations, distractions, or, when communicating online, technical hiccups that may cause brief delays. Research among previously unacquainted individuals revealed that brief disruptions in conversational flow can have profound social consequences: Silences or delays in mediated communication threaten the need to belong and validate one’s ideas. The present research, however, shows that when occurring in close relationships, flow disruptions may be ironically beneficial. We hypothesized that when flow disruptions occur, partners fall back on their relationship beliefs to infer mutual agreement and the existence of a shared reality. When a relationship is perceived as secure, partners may believe that “no words are needed” to understand each other. Flow disruptions can thus paradoxically make shared cognitions accessible and foster feelings of social validation. Data from two experiments, using partners in different types of relationships, supported this hypothesis.

Regulating shared reality with micro-dynamics in the form of conversation

One of the central goals within communication is to establish whether people are on the same wavelength. Although such assessment can occur objectively, by exchanging and comparing viewpoints, people may also derive a sense of shared reality subjectively, through micro-dynamics in the form of conversation that inform them whether their views are shared. The present review outlines the role of these micro-dynamics in developing and regulating a shared reality. It focuses on three different contexts: intergroup communication, computer mediated communication and communication within intimate relationships. The review concludes with a discussion of the power of micro-dynamics in comparison to more explicit forms of social validation.

The polarizing effects of group discussion in a negative normative context: Integrating societal-, group-, and individual-level factors

In this research, we investigate how a negative (or hostile) norm regarding minorities at the societal level can fuel polarization between majority subgroups at the local level. We hypothesize that rapid social change in the form of polarization results from the interplay between small group processes and perceptions of society at large. By employing a novel analytic approach that uses variances to capture non‐linear societal change, we were able to study polarization processes. In three studies among high school and university students (N = 347), we manipulated the majority norm about a minority category (positive vs. negative). Subsequently, participants read about a minority members ambiguous behaviour and evaluated this target. All studies used a similar paradigm, but they varied in whether or not participants discussed the ambiguous behaviour within local groups. Results showed that the majority norm at the societal level affected perceptions of the minority members behaviour when people discussed this behaviour in a local majority group but not when they reflected on it individually. Specifically, group discussions led to polarization between local groups within a broader social category, but only in the context of a negative majority norm. This effect was predicted by the a priori perception of the local group norm. Results are discussed in terms of the integration of society‐ and group‐level processes when studying the development of intergroup attitudes and practical implications for the coarsening climate of the societal debate about current societal issues.
