this conception can be found in some of the works of sociologists such as Georg Simmel, Emile Durkheim and to some extent Robert Park. Interactive social distance: Focuses on the frequency and intensity of interactions between two groups, claiming that the more the members of two groups interact, the closer they are socially. This conception is similar to the approaches in sociological network theory, where the frequency of interaction between two parties is used as a measure of the "strength" of the social ties between them. Cultural and habitual distance: Focuses cultural and habitual which is proposed by Bourdieu (1990). This type of distance is influenced by the "capital" people possess. It is possible to view these different conceptions as "dimensions" of social distance, that do not necessarily overlap. The members of two groups might interact with each other quite frequently, but this does not always mean that they will feel "close" to each other or that normatively they will consider each other as the members of the same group. In other words, interactive, normative and affective dimensions of social distance might not be linearly associated. Measurement Some ways social distance can be measured include: direct observation of people interacting, questionnaires, speeded decision making tasks, route planning exercises, or other social drawing tasks (see sociogram). Bogardus Social Distance Scale and its variations remain the most popular measure of social distance. In questionnaires based on Bogardus’ scale, respondents are typically asked members of which groups they would accept in particular relationships. For example, to check whether or not they would accept a member of each group as a neighbor, as a fellow worker as a marriage partner. The social distance questionnaires may not accurately measure what people actually would do if a member of another group sought to become a friend or neighbour. The social distance scale is only an attempt to measure one's feeling of unwillingness to associate equally with a group. What a person will actually do in a situation also depends upon the circumstances of the situation. Theoretical implications Psychological distance Some researchers have examined social distance as a form of psychological distance. Research in this vein has drawn connections between social distance, other kinds of psychological distance (such as temporal distance). This type of work also examined the effect of social distance on construal levels, suggesting that greater social distance promotes high-level and increase cognitive abstraction. In
