Prevention, Adaptation, and Threat Denial: Flooding Experiences in the Netherlands

Delta areas such as the Netherlands are more and more at risk of future flooding due to global climate change. Motivating residents living in flood-prone areas to effectively cope with local floods may lead to minimization of material losses and loss of life. The aim of this research was to investigate whether the extent to which residents had been exposed to flooding in the past was a key factor in motivating residents to effectively cope with future flooding. We also focused on the psychological variables that mediated this relationship. We conducted a survey (N = 516) among flood victims and nonvictims. We assessed subjective experiences due to past flooding, affective and cognitive appraisals, and coping responses. Results show that victims reported stronger emotions (negative and positive), and the receipt of more social support due to past flooding than did nonvictims. Moreover, victims worry more about future flooding, perceive themselves as more vulnerable to future flooding, perceive the consequences of future flooding as more severe, and have stronger intentions to take adaptive actions in the future than nonvictims. Structural equation modeling reveals that the latter effect was fully mediated by specific experiences and appraisals. Insights into factors and processes that have the potential to motivate residents to effectively cope with future floods may prove helpful in developing interventions to inform residents how to act effectively in case of an imminent flood.

Role of negative emotion in communication about CO2 risks

This article describes how the effectiveness of risk communication is determined by the interaction between emotional and informative elements. An experiment is described that examined the role of negative emotion in communication about CO2 risks. This experiment was based on the elaboration likelihood model and the related heuristic systematic model of attitude formation. The results indicated that inducing fear of CO2 risks leads to systematic processing of information about energy conservation as a risk-reducing strategy. In turn, this results in more favorable attitudes toward energy conservation if strong arguments are provided. Individual differences in concern seem to have similar effects.

The role of similarity cues in the development of trust in sources of information about GM food.

In evaluating complex new technologies, people are usually dependent on information provided by others, for example, experts or journalists, and have to determine whether they can trust these information sources. This article focuses on similarity as the basis for trust. The first experiment (N = 261) confirmed that a journalist writing about genetically modified (GM) food was trusted more when his attitude was congruent with that of his readers. In addition, the experiment showed that this effect was mediated by the perceived similarity of the journalist. The second experiment (N = 172) revealed that trust in a journalist writing about the focal domain of GM food was even influenced by him expressing a congruent attitude in an unrelated domain. This result supports a general similarity account of the congruence effect on trust, as opposed to a confirmatory bias account.

The persuasive power of mediated risk experiences

This paper discusses the use of multimedia techniques and augmented reality tools to bring across the risks of global climate change. We look back on a series of experiments showing that vividness is a key factor in creating emotional risk responses and fostering attitude change through systematic information processing. However, the effects were modest even when vivid and concrete images and texts were used in combination with ominous sounds and music. The next step therefore is to explore and make use of the possibilities of multimedia techniques and augmented reality to provide people with a simulated risk experience. This paper concludes with a preview of this work, the focus of which is on the sense of presence.

The role of fear and threat in communicating risk scenarios and the need for actions: Effect of fear on information processing

This paper is about the role of fear and threat in communicating risk scenarios and the need for actions. The results of our first experiment are discussed, in which we examined whether fear of environmental risks increases the tendency to carefully process information on environmentally sound behaviour.
