The overview effect refers to a profound reaction to viewing the earth from outside its atmosphere. The astronauts that have experienced this describe it as having deep feelings of awe and self-transcendence. Short- and long- term emotional benefits are attributed to these experiences. The intense and singular states of awareness triggered by viewing the Earth from space provide a new context in which to explore awe-inspiring stimuli, their psychological effects, and individual differences in sensitivity to such potentially transformative experiences.
Astronauts that have experienced the overview effect characterise it as follows; a transformative experience involving senses of wonder and awe, unity with nature, transcendence and universal brotherhood, overcome by emotion, see the world and themselves differently, returned to Earth with a new sense of purpose. The astronauts state that its not just spending time in space but viewing and contemplating the Earth from a distance that brings about the overview effect. Other characteristics of the overview effect are; appreciation and perception of beauty, unexpected emotion and an increased sense of connection to other people and the Earth as a whole. Other components associated with the overview effect are: changes in space perception, changes in time perception, the experience of silence and the experience of weightlessness.
Astronauts said they experienced awe. Awe is characterised as an intense emotion resulting from the perception of something vast, as well as the need to accommodate the experience, by social psychologists. It can occur in both natural and social situations, the emotion often overlaps with wonder, fear and curiosity. Awe correlates with wonder and the witnessing of power, as a result people can mimic behaviours, become submissive and experience heightened attention. The features of the astronauts viewing of the Earth contribute to the feeling of awe. The contrast between the Earths features and the black background of space. Presenting a well-known natural and human feature from a radically different perspective.
Awe alone does not make up the overview effect, Self-transcendent experiences also play a part. STEs are temporary feelings of unity characterized by reduces self-salience and increased feelings of connection. During these kinds of experiences, people can feel a sense of connection with other individuals, humankind and even the entirety of existence. In the case of the overview effect, that sense of connection may encompass the entirety of Earth and its inhabitants. The overview effect might be best understood as a state of awe with self-transcendent qualities, brought about by a particularly striking visual stimulus.
The experience of awe and self-transcendence are episodic and of fleeting nature, but astronauts experience some long-term changes in their personal outlook and attitude involving the individual’s relationship to the Earth. These changes primarily entail a greater affiliation with humanity as a whole as well as an abiding concern and passion for he well-being of Earth.
Subjective experiences can shape the ways in which individuals understand and approach new concepts, and even affect the salience of familiar concepts. These changes are conscious and propositional, and can influence an individuals broader beliefs and values. On way to understand this powerful influence might be in terms of alternations to a schema. A schema is an organized conceptual framework thorough which individuals approach new information and make sense of old experiences. When an experience does not fit into the pre-existing schema they have to accommodate by expanding the framework to take new information into account. This accommodating remains even after the experience ends and thus has a lasting effect on the individual and is influential in shaping his or her sense of self.
The overview effect can be understood in terms of awe and self-transcendent experiences, with contributing changes to the observer’s self-schema and value system, which in some cases could be considered transformative.
