Within the framework of an international research project aimed at studying the impact of different cultural settings on gerotranscendent development, six groups of older people distinguished by religiosity and cultural origin were studied. A life history approach, followed by thematic semi-structured interviews, was applied. One of the objectives was to inquire about the possible impact of religion, conceived of as a cultural setting, on development towards gerotranscendence. The findings of this inquiry gave rise to two hypotheses as to the relationship between gerotranscendence and religiosity. The first hypothesis is that the internalisation of mystical-type ideas in individuals' ways of thinking is probably a factor involved in the development of a gerotranscendent view of life. In other words, whether individuals practice their ‘religion’ in a spiritual, nonorganisational way, or in an organisational way, may play a role for development towards gerotranscendence. The second hypothesis is that certain characteristics, such as the secular and individualistic features of modern societies, may delay development towards gerotranscendence.
