Pressure is the degree to which external forces act upon a person to approach/enter or avoid/withdraw from the setting. For example, a setting can be required (a child is for a class at school), invited (a child welcomed to a Sunday School class), or prohibited (a child is excluded from a bar). Welfare is the relevance of the setting to a particular group of inhabitants; that is, whether the group is served by the setting, whether the group serves others in the setting, or whether the setting instigates and supports other settings relevant to the group. Finally, the Local Autonomy of the behavior setting is the geographic level at which the setting's operations are determined (e.g., town, district, county, state).
