1 Origin and Evolution of Cultural Level Organization AILUN Lecture 6 Adapted from Glenn, S. S. (2004). Individual Behavior, culture, and social change. The Behavior Analyst, 27,

2 Culture Defined: Patterns of learned behavior transmitted socially, as well as products of that behavior (objects, technologies, institutions) Prerequisites: social species, uncommitted behavior, susceptibility to operant processes Level of analysis: supraorganismic involves interlocking behavioral contingencies of multiple organisms No new behavioral processes -- each organism s operant behavior still analyzed in terms of behavioral principles operating at the level of the individual organism Reasons for similarities in content of human operants similarities in non-social or social environments result in independently produced similarities of operants in different repertoires (no cultural transmission) social environmental events incidentally contribute to similarity similarity systematically programmed via contrived socially mediated contingencies

3 Cultural Practices Defined: similar patterns of behavioral content, usually maintained by similar environmental content Examples Twiggy hair style Driving stick-shift automobiles Presenting professional papers Point of transmission may be a single link between behavior of transmittor and transmittee Hair stylist A may create style pictured in a magazine (or in person) and other hair stylists produce a similar result, which may be repeated many times Hair stylist A demonstrates styling hair and stylist B imitates A s activities, producing a similar result (B repeats many times with many patrons)

4 Cumulative Effect of Cultural Practices Examples Smoking contributes to illnesses, increases public health cost Dumping waste in waterways kills wildlife, causes illness Running air conditioners affects ozone layer, increases incidence of skin cancer Driving cars depletes fossil fuel reserves, drives up cost of gasoline

5 Macrocontingencies 1 Defined: Patterns of similar behavior (cultural practice) and their cumulative effects Example P1 drive to work 1 ltr gasoline P2 drive to work.5 ltr gasoline P3 drive to work.3 ltr gasoline P4 drive to work.2 ltr gasoline Cumulative effect 2 ltr/1 day/1 way 1000 ltr annually No need for cultural level selection to explain the behavior or the cumulative effect: behavioral principles are sufficient

6 Engineering Change in Macrocontingencies Arrange environment to bring about change in behavior of many individuals Implement reinforcement contingencies for car pooling (HOV lanes) Implement punishment contingencies for consumption (higher price) Social approval of conservation gradually becomes common P1 drives to work,taking P2, P3, P4 P2 rides with P1 P3 rides with P1 P4 rides with P1 1.5 gal 1way/1day 750 gal annually

7 Recurring Interlocking Behavioral Contingencies In repetitions of a particular situation, Person A s behavior repeatedly constitutes the environmental events participating in Person s B s operant contingencies and vice versa Example: Marta and Todd regularly cook meals together o The repeating pattern of interlocking behavior for each twosome is maintained by the outcome of interlocking behavioral contingencies for that twosome o Each twosome s interlocking behavioral contingencies constitutes a cultural lineage o Each time the pattern is instantiated it produces an outcome o The outcomes (meals) may serve as back-up reinforcers for all the behaviors of each actor and it may also serve to maintain the pattern of interlocking contingencies o This repeating pattern is a cultural practice if different actors independently participate in a similar repeating pattern of interlocking behavioral contingencies (Jim and Sam also regularly cook meals together, as do Jordan and Linda and many other twosomes)

8 Selection in the Evolution of Cultural Organization Level of analysis: interrelated behavior of two or more organisms Schematic representation of cultural level contingencies of selection (metacontingencies) Organisms O, O, O Situation S Environment IBC1 IBC2 IBC1 IBC3 IBC1 IBC1 IBC4 IBC5 IBC1 Iterations C1 C1 C1 C1 C1 Environment Interlocking Behavioral Contingencies 1 All IBC1 recurrences constitute a particular cultural lineage

9 Metacontingencies Defined: Temporal relations between recurring interlocking behavioral contingencies and their consequent environment that account for frequency, form, or other properties of the lineage of recurring interlocking behavioral contingencies Example: Relation between Tom and Marta s pattern of interlocking behavior and the resulting meals accounts for adjustments in the pattern Operant contingencies are embedded in the cultural entities that participate in metacontingencies Interlocking behavioral contingencies may be hierarchically nested as cultural organization becomes more complex

10 Engineering Change in Metacontingencies Identify the interlocking behavioral contingencies that produce an aggregate outcome Change the metacontingency so that alternative interlocking behavioral contingencies are selected Change the behavioral contingencies embedded in the interlocking behavioral contingencies to produce a change in aggregate outcome

11 Schematic of Cultural Level Intervention Problem: High frequency of pedestrian casualties in Brasilia Cross wide streets with fast traffic, not in crosswoaks Drivers not yielding to pedestrians Problem is cultural antecedent for IBC formation Participants in IBCs repeatedly produce an aggregate product: activity designed to change behavioral contingencies for drivers The aggregate product leads to a change in operant contingencies for drivers and pedestrians The change in operant contingencies results in lower frequency of pedestrian casualties Lower frequency of pedestrian casualties functions as cultural consequence maintaining IBCs

12 Similar driver Operants & pedestrian O s CP1 A A A A W W W W CP2 Cumulative cultural product Large number of pedestrian injuries Interlocking behavioral contingencies Aggregate Product Z Z Z CP3 Z Y Y Y CP4 Y Cultural consequence (Maintains IBCs) Smaller number of traffic injuries (running over) Macrocontingency Church and product Media and product Police and product Traffic Dep. and product Brasília University and product Metacontingency Macrocontingency CP1- Not respecting crosswalk (drivers) CP2- Crossing outside of the crosswalk (pedestrians) CP3- Respecting crosswalk (drivers) (drivers) CP4- Crossing inside of the crosswalk (pedestrians)
