This study examined the contribution of general normative beliefs about aggression and specific normative beliefs about retaliatory aggression in predicting physical, verbal, and indirect aggressive behaviors. Two hundred and forty-nine Grade 4 and Grade 5 boys completed the Normative Beliefs about Aggression Scale (NOBAGS) and provided self-reports on the frequency of their physical, verbal, a...

The general equilibrium analysis of perfectly competitive markets plays a central role in most attempts by positive economics to describe what happens in a market economy. It is usually admitted that there may be barriers to competition, that markets may be incomplete, and information may be lacking. Nevertheless, as a theoretical ideal which may approximate reality, general equilibrium analysi...

The Sznajd model for opinion dynamics has attracted a large interest as a simple realization of the psychological principle of social validation. As its most salient feature, it has been claimed that the Sznajd model is qualitatively different from other ordering processes because it is the only one featuring outflow of information as opposed to inflow. We show that this claim is unfounded by p...

We articulate the role of norms within the social identity perspective as a basis for theorizing a number of manifestly communicative phenomena. We describe how group norms are cognitively represented as context-dependent prototypes that capture the distinctive properties of groups. The same process that governs the psychological salience of different prototypes, and thus generates group normat...

This study provides insight into how social relationship factors influence on electronic Word-of-Mouth (EWOM) behaviors in social networking sites. By using the sample from Taiwan and Vietnam college students who spend more time on social networking sites, we investigate these determinants of EWOM behaviors such as social capital, trust and interpersonal influences, and compare the results betw...

In two experiments, we show how a consumer’s susceptibility to normative influence (SNI) offers useful insights into the effectiveness of two types of testimonials: a typical person endorsement (Study 1) and a celebrity endorsement (Study 2). Specifically, we suggest that two variables moderate testimonial effects—SNI and product attribute information. Results show that in forming their evaluat...

In Poland, invitro fertilisation technology (IVF) has been in use for over 25 years, garnering success and social approval. However, in 2007, a heated debate erupted on the moral, legal and economic aspects of IVF. A growing chorus of emphatic Catholic voices calls for IVF to be banned. This paper focuses on ‘naprotechnology’, a new actor and a fresh card in Poland’s IVF debate. This method of ...

This paper demonstrates the relevance of consumers’ susceptibility to interpersonal influence (CSII) in an investment context. In Study 1, a survey of individual investors, investment-related knowledge, psycho-social risks, and social needs emerge as antecedents that explain investors’ susceptibility to informational and normative influence. In turn, susceptibility to normative influences incre...

We show how different approaches to developing marketing strategies depend on the type of environment a firm faces, where environments are distinguished in terms of their systems properties rather than their content. Particular emphasis is given to turbulent environments in which outcomes are not a priori predictable and are not traceable to individual firm actions and we show that, in these co...
