Significant Life Experiences Revisited: a review of research on sources of environmental sensitivity

Beginning with the study of significant life experiences initiated by Tanner, this article reviews a growing body of related research in the form of surveys, interviews, and questionnaires that explore people's accounts of the sources of their environmental interest, concern, and action. The questions, methods, and results of studies in this field are closely compared. In conclusion, the article notes that the experiences that people describe can be understood as exchanges between the ‘outer environment’ of the physical and social world and the ‘inner environment’ of people's own interests, aptitudes, and temperament, and that more attention needs to be paid to the influence of this ‘inner environment’ of individual differences.
