Abstract
The present study introduces the Extreme Climate Event Database (EXCEED), a picture database intended to induce emotionally salient stimuli reactions in the context of natural hazards associated with global climate change and related extreme events. The creation of the database was motivated by the need to better understand the impact that the increase in natural disasters worldwide has on human emotional reactions. This new database consists of 150 pictures divided into three categories: two negative categories that depict images of floods and droughts, and a neutral category composed of inanimate objects. Affective ratings were obtained using online survey software from 50 healthy Brazilian volunteers who rated the pictures according to valence and arousal, which are two fundamental dimensions used to describe emotional experiences. Valence refers to the appraisal of pleasantness conveyed by a stimulus, and arousal involves internal emotional activation induced by a stimulus. Data from picture rating, sex difference in affective ratings and psychometric properties of the database are presented here. Together, the data validate the use of EXCEED in research related to natural hazards and human reactions.
Highlights
IntroductionWith the increasing number of events caused by global warming (e.g., heavy precipitation events, floods, hurricanes, wildfires and heat waves), more and more people around the world will be affected
Worldwide, people are facing disasters caused by climate change
The doubts raised about how to cope with immediate or long-term consequences of natural hazards motivated the development of the Extreme Climate Event Database (EXCEED)
Summary
With the increasing number of events caused by global warming (e.g., heavy precipitation events, floods, hurricanes, wildfires and heat waves), more and more people around the world will be affected. Such circumstances affect humans in different ways that could potentially lead to both mental health issues and/or have an impact on a broad range of adversities to the economic, social and environmental field [1,2,3].
