Ecological units exist at the interface between the ecological environment and certain practice of molar behavior. These units exist in the physiological, social, psychological, and behavioral realms and share three common attributes:
An ecological unit is a composite of an environment piece and a behavior piece. They are hybrid artifacts that exist as quasi-objective entities, much like Searle's "observer-relative features of the world".2 An example that Barker used in 19683 is a road—a road is a track (physical feature) used for travelling or carrying goods (expression of 'molar behavior'). The coupling of a molar behavior to an environmental feature (affordance) is the mechanism through which the reciprocal relations between different levels of nested or related phenomena occur. The ecological unit is the foundation for the concept of a 'behavior setting' which was defined above. More generally, it seems that this notion captures the relationship of any organism to its niche and is captured by Reed in his 1996 discussion of the 'affordance'.4
Barker also develops a useful analogy for conceptualizing this relation, as well as preparing readers for later claims about behavior settings. He observes that 'molar behavior' is to the 'ecological environment', just as 'visual perception' is to 'light'; i.e., in order to understand visual perception, you have to understand light, independent from visual perception. If we were only to look at the eye-optic channel at the instant that light hit the receptor surface, we would know nothing of depth of field, focus, or perspective.
The behavior setting concept could be very useful in the field of architectural programming, architectural design, as well as in urban planning and design. It is the very challenge for behavior setting theory today to be used in those fields: architects and behavioral scientists still are not in full contact in design and research issues. The kind of ecological unity devised by Roger Barker connects strongly and consistently behavior and physical features of ordinary - and those not-so-ordinary settings in universities, labs, hospitals, etc.
According to Barker in 1968,5 conducting a behavior setting survey consists of the measurement of eleven key descriptive attributes:
There are two temporal attributes: Occurrence (O), the number of days in a year the behavior setting is capable of occurring, and Duration (D), the number of hours the behavior setting functions during a year. Population (P) is the number of different persons who inhabit the behavior setting during the year. These three basic attributes allow for a calculation of Occupancy Time (OT), the number of person-hours spent in the behavior setting. It is the product of the occurrences (O), the average number of inhabitants per occurrence (P/O), and the average duration per occurrence (D/O).
Penetration (Pe) is the degree to which an inhabitant is involved in the setting and consists of six incremental zones, ranging from onlooker to leader. Using these divisions, the average depth of penetration can be determined for population subgroups (e.g., frequency of minority students being leaders in a club).
Action Patterns (AP) are the functional attributes of the patterns of behavior (e.g., religion, education, and recreation). For each action variable, researchers note the activity's frequency (participation subscale), its production of materials for use in another setting (supply subscale), and whether the activity is evaluated (appreciation subscale). Behavior Mechanisms (BM) are the modalities through which behavior is implemented in the setting, such as gross motor activity, talking, or thinking. Researchers note each mechanism's frequency (participation subscale), the speed of the behavior (tempo subscale), and the expenditure of energy (intensity subscale).
Richness is a composite measure of the variety of behavior within the setting. It is computed from the prior attributes using the following formula: (ΣPe + ΣAP + ΣBM)OT/100
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).
