The first objective of this article is to obtain a comprehensive review based inter alia on the findings of several fields in research on creativity and performance, i.e. management, psycho-sociology and neurology. This conceptual contribution shows that emotional contagion is proved to have an influence on the group performance, but remain under studied in its action on creativity. The second objective is to study those links on 223 Young professionals in training. If the results show a relation between group cohesiveness and performance, they show a surprising result, there is no relation between group cohesiveness and creativity. Emotional contagion, enhance the first link but don’t change the second. Thanks to the analysis based on through several fields of research, the article ends up with an opening on one management tool of creativity, we can call the 'self sustaining area' -based on the emotionalized zone- needed for both individual and collective inspiration. Key Words: Emotional Contagion, Group And Individual Creativity, Cognitive Processes, Management Tool.

Payment for Environmental Services (PES) has been analysed in many countries, but few studies address the influence of urban and rural characteristics on the perception of PES results. The aim of this study is to compare the perceptions of Mexican hydrological PES programme results in a peri-urban community close to Mexico City and in a rural community on Oaxaca state. Despite some similarities between the two communities, we find evidence of some differences in their peri-urban and rural characteristics, in their PES understanding, operation and effects. Those differences are related to individuals’ close contact with natural resources in the rural area, opportunity costs, income diversification, and intermediaries. The reflections also suggest that it is important to analyse deeper the PES programme context, because there are differences in environmental, economic and social aspects that influence the effects of PES in terms of motivations, economics and institutional arrangements. Key Words: Payments for Environmental Services, Rural and Peri-Urban Characteristics, Mexico.
