Efeitos de um Análogo de Reforçamento Negativo sobre a Seleção de Culturantes / Effects of an Analogue of Negative Reinforcement on the Selection of Culturants

Resumo O presente estudo investigou os efeitos de um análogo de reforçamento negativo sobre a seleção de culturantes e, diferentemente de estudos anteriores, buscou eliminar a interferência da punição negativa de outros culturantes. Três microculturas de laboratório, com três participantes cada, foram expostas a um delineamento ABAB. Os participantes escolhiam entre linhas coloridas e numeradas de 1 a 10. Na condição de Reforçamento Positivo (A), os culturantes-alvo produziam consequências culturais. Na condição de Reforçamento Negativo (B), as consequências culturais eram subtraídas a cada 30s, mas os culturantes-alvo podiam adiar a perda dessas consequências. O análogo de reforçamento negativo, assim como o de reforçamento positivo, selecionou os culturantes-alvo sem a interferência de contingências punitivas acidentais.

Abstract The present research investigated the effect of a negative reinforcement analog on the selection of culturants and, unlike previous studies, sought to eliminate the interference of the negative punishment of other culturants. Three laboratory microcultures, with three participants in each of them, were exposed to an ABAB design. The participants chose between colored lines, numbered from 1 to 10. In the Positive Reinforcement condition (A), target culturants produced cultural consequences. In the Negative Reinforcement condition (B), cultural consequences were subtracted every 30 seconds, but target culturants could delay the loss of those consequences. The analog of negative reinforcement, as well as that of positive reinforcement, selected target culturants without the interference of accidental punitive contingencies.

Seleção de práticas culturais complexas: avaliação experimental de um análogo do procedimento de aproximação sucessiva / The selection of complex cultural practices: experimental assessment of an analogous of the successive approximation procedure

O processo de evolução cultural tem sido investigado experimentalmente na Análise do Comportamento com base no conceito de metacontingências, que descreve a relação funcional entre contingências comportamentais entrelaçadas (CCEs), seu produto agregado (PA) e consequências culturais (CCs) liberadas por um sistema receptor. Neste estudo, buscou-se investigar a possibilidade de selecionar um dado entrelaçamento (um padrão de comportamentos coordenados entre os membros de um grupo) com um análogo doprocedimento de aproximação sucessiva, usado na modelagem do comportamento individual. Dois grupos de quatro universitários foram expostos a procedimentos de aproximação sucessiva em arranjos de metacontingências. Os entrelaçamentos alvo tinham graus de complexidade quevariavam quanto ao número de exigências para a produção da CC (complexidade ambiental) e quanto ao número de membros do grupo (complexidade de componente). No Experimento 1, foi programado o aumento gradual da complexidade ambiental e, no Experimento 2, o aumento gradual e simultâneo de complexidade de componente e ambiental. A tarefa dos grupos consistiade escolher linhas em uma matriz de dez linhas de cinco cores diferentes, numeradas de 1 a 10, e dez colunas, nomeadas de A a J. Contingências individuais e contingências culturaisfuncionalmente independentes umas das outras foram programadas. Escolhas individuais de linhas ímpares produziam fichas trocáveis por dinheiro (consequência individual); escolhas delinhas com certas coordenações de cores produziam itens escolares para doação a uma escola pública (CCs). Os resultados do Experimento 1 (modelagem de CCEs com complexidade ambiental crescente) demonstraram a seleção de CCEs alvo. No Experimento 2, não houve seleção dos entrelaçamentos alvo. Esse resultado demonstra a possibilidade de modelagem de CCEscomplexas empregando-se o procedimento de aproximação sucessiva, ao mesmo tempo em quesugere que a progressão simultânea de várias dimensões da complexidade do entrelaçamento pode comprometer a eficácia do procedimento na produção de unidades culturais complexas. Todavia, certas características do preparo experimental empregado neste experimento sugerem que outras variáveis (notadamente, a alternância das funções dos membros do grupo) podem ter concorrido com o procedimento de aproximação sucessiva e afetado a sua eficácia.

Cultural evolution has been the subject matter of experimental investigation in Behavior Analysis, under the concept of metacontingency. Metacontingencies describe the functional relationship between interlocking behavioral contingencies (IBCs), their aggregateproduct (AP), and cultural consequences delivered by a receiving system. In this study, we investigated the selection of IBCs (a pattern of coordinated behaviors of the members of a group), employing an analog of the successive approximation procedure, employed in modelling individual behavior. Two groups, four undergraduate students in each, were exposed to a successive approximation procedure in a metacontingency setting. The target IBCs involved degrees of complexity that varied with respect to the requirements to produce the CC(environmental complexity), and to the number of group members (component complexity). In Experiment 1, a gradual increase in environmental complexity was programmed. In Experiment 2,there was a gradual and simultaneous increase in both component and environmental complexity. The task to be performed consisted of choosing rows in a 10x10 matrix, in whichrows were of five different colors, numbered from 1 to 10, and columns were named from A to J. Individual contingencies, as well as functionally independent cultural contingencies were programmed. Individual choices of odd rows produced tokens exchangeable for money(individual consequence); choices of rows of given coordinations of colors (IBCs+PAs) produced school itens to be later donated to a public school (CCs). Results of Experiment 1 (modelling ofIBCs with increasing environmental complexity) showed the selection of target IBCs. In Experiment 2, the target IBCs were not selected. These results show that the successive approximation procedure may be effective in the modelling of IBCs, and suggests, as well, that simutaneous progression of both environmental, and component complexity dimensions may affect the efficacy of the procedure in producing complex cultural units. However, some aspects of the experimental preparation employed in this study also suggest that other variables (namely, the changing functions of the group members) may have competed with the successiveapproximation procedure and affected its efficacy.

The Selection Metaphor: The Concepts of Metacontingencies and Macrocontingencies Revisited / La metáfora de la selección: una revisión de los conceptos de metacontingencia y macrocontingencia

Las explicaciones tradicionales de la conducta cultural se fundamentan en una perspectiva seleccionista. Sin embargo, varias discusiones teóricas se han preguntado sobre la misma y sobre la identificación de unidades de selección. Argumentaré que, si bien las propuestas centrales de Glenn constituyen una extensión valiosa de los principios operantes, el enfoque seleccionista ha entorpecido el desarrollo conceptual y empírico de la teoría. Se presenta un examen de las nociones fundamentales de la teoría de la evolución cultural; específicamente, una revisión de los conceptos de metacontingencias, contingencias conductuales entrelazadas, macrocontingencias y productos agregados, en términos de su contribución a una explicación válida y significativa del comportamiento cultural. Se sugiere que se requieren análisis experimentales funcionales para identificar el control de la conducta por parte de contingencias individuales o grupales, incluyendo los productos acumulados y agregados.

Current mainstream accounts of cultural behavior are strongly founded on a selectionist perspective. However, more than a few theoretical discussions have emerged regarding the appropriateness of the subject matter and the identification of units of selection. I argue that although Glenn's central formulations constitute a valuable extension of operant principles, the selectionist approach has hindered the theory's conceptual and empirical development. An examination of the fundamental notions included in the theory of cultural evolution is presented. Specifically, we review the concepts of metacontingencies, interlocking behavioral contingencies, macrocontingencies, and aggregate products in terms of their contribution to a valid and significant account of cultural behavior. It is suggested that experimental functional analyses are required to identify control of behavior by local contingencies or group consequences including cumulative and aggregate products.

Metacontingencies, Cultural Selection and Social/Verbal / Metacontingencias, Selección Cultural y Ambiente Social/Verbal

Resumen En las últimas décadas, Sigrid Glenn, a partir de la proposición del concepto de 'metacontingencia', ha desarrollado una propuesta analítico-conductual que busca ampliar el tratamiento skinneriano de los procesos de selección/ evolución cultural. Este artículo presenta inicialmente una descripción del desarrollo conceptual de esta propuesta. A continuación, teniendo en cuenta la importancia que se le ha asignado a repertorios verbales en el proceso de selección cultural, se presentan las propuestas de los antropólogos Terrence Deacon y Marvis Harris que abordan la relación entre la evolución de ambientes sociales/verbales y la selección/evolución de prácticas culturales. Por último, basándose en estas propuestas, se discuten formas en que el control de la conducta individual por el grupo - y sus agencias de control - sugieren un creciente desarrollo de mecanismos de control verbal/social, lo que indica la importancia de fomentar el estudio de las relaciones entre la evolución de ambientes sociales/verbales y la selección/ evolución de prácticas culturales.

In the last decades, Sigrid Glenn, from the proposition of the concept of 'metacontingency', has developed a behavioral-analytic proposal that seeks to amplify the Skinnerian treatment given to cultural selection/evolution processes. This paper initially presents a description of the conceptual development of this proposal. Afterwards, considering the importance that has been assigned to verbal repertoire in the cultural selection process, proposals from anthropologists Terrence Deacon and Marvis Harris, who approach the relationship between the evolution of social/verbal environments and the selection/evolution of cultural practices, are presented. Finally, based on these propositions, forms in which the control of individual behavior by the group - and by their controlling agencies - seems to denote an increasing development in verbal/ social control mechanisms are discussed, indicating the importance to go more deeply into the study of relationships between the evolution of social/verbal environments and the selection/evolution of cultural practices.

Analyzing Behavioral and Cultural Selection Contingencies / Analizando las contingencias de selección conductual y cultural

Se utilizó un paradigma de elección para evaluar la distribución del comportamiento entrelazado de dos grupos de dos participantes entre respuestas que tenían solo consecuencias operantes y respuestas con consecuencias culturales. En un diseño BABABAB de ensayo discreto, cada participante podría seleccionar una de tres opciones, que entregaba 3 o 5 puntos. En las condiciones B (consecuencia cultural), dos de las opciones tenían efectos adicionales: la opción de tres puntos también sumaba 3 puntos a las ganancias del otro participante, y una de las opciones de 5 puntos quitaba esa cantidad de las ganancias del otro participante. La tercera opción era igual en ambas condiciones y le entregaba 5 puntos al participante que la elegía. Los resultados indicaron que los participantes en ambos grupos inicialmente produjeron combinaciones de respuestas que ganaban 8 puntos para un individuo u otro frecuentemente (y 0 o 3 para el otro), pero la distribución de respuesta cambió hacia combinaciones de 6 puntos para cada individuo. Este paso de refuerzo máximo individual hacia máximo refuerzo grupal indica que las contingencias culturales no actuaron de acuerdo con las contingencias operantes, lo que sugiere la presencia de diferentes mecanismos de selección.

A choice paradigm was used to evaluate allocation of interlocking behavior of two groups of two participants between responses having operant consequences only, and responses having cultural consequences. In a discrete trial BABABAB design, each participant could select one of three options, which delivered either 3 or 5 points. In B (cultural consequence) condition, two of the options had additional effects: the 3-point option also added 3 points to the other participant's earnings, and one of the 5-point options also subtracted 5 points from the other participant's earnings. The third option was unchanged in both conditions and delivered 5 points to the participant who selected it. Results indicated that participants in both groups initially frequently produced response combinations that earned 8 points for one or the other individual (and 0 or 3 points for the other), but allocation of responding increasingly changed to combinations that produced 6 points for each individual. This shift in performances away from maximum individual reinforcement towards maximum group reinforcement indicates cultural contingencies did not act in concert with operant contingencies, suggesting they are different mechanisms of selection.

An Iterated Four-Player Prisoner's Dilemma Game with an External Selecting Agent: A Metacontingency Experiment / El juego del "Dilema del Prisionero" con cuatro participantes y un agente selector externo: un experimento metacontingencia

En esta serie de experimentos utilizamos un juego iterativo del "Dilema del Prisionero" (IPDG por sus siglas en inglés) para examinar el efecto de las metacontingencias sobre los productos agregados del comportamiento interrelacionado de cuatro jugadores. Los resultados del primer experimento muestran que las consecuencias de nivel cultural ("retroalimentación del mercado" en la forma de puntos entregados a todos los jugadores), contingentes con los productos agregados XXX o YYYY aumentaron la frecuencia de esas producciones. En experimentos posteriores, añadimos una condición de línea de base en la cual los jugadores experimentaron solo las contingencias conductuales individuales incorporadas en el juego. Luego impusimos la metacontingencia sobre el producto agregado XXXX, o de forma alternativa sobre YYYY. Después de varias reversiones, descontinuamos la metacontingencia y los jugadores comenzaron a experimentar nuevamente solo las contingencias individuales del juego. En un experimento utilizamos un control para evaluar el efecto de la retroalimentación del mercado de manera independiente de la relación metacontingencial. Los resultados indican que la consecuencia cultural (retroalimentación del mercado) controló la producción de productos agregados incluso cuando su magnitud era mínima, que la relación metacontingencial era necesaria, y que mantenía relaciones en el comportamiento de los individuos que tenían los peores resultados para todos los jugadores.

In these series of experiments we used an iterated prisoners' dilemma game (IPDG) to examine the effect of metacontingencies on aggregate products of the interrelated behavior of four players. Results of the first experiment showed that cultural level consequences ("market feedback" in the form of points delivered to all players) contingent on aggregate products XXXX or YYYY increased the frequency of those productions. In subsequent experiments we added a baseline condition where the players experienced only the individual behavioral contingencies embedded in the game. Then we imposed the metacontingency on the XXXX aggregate product or, alternatively, on YYYY. After several reversals, we discontinued the metacontingency and the players again experienced only the individual contingencies of the game. In one experiment we used a yoked control to assess the effect of market feedback independent from the metacontingency relation. Results indicate that the cultural consequence (market feedback) controlled production of aggregate products even when its magnitude was minimal, that the metacontingency relation was necessary, and that it maintained relations among the behavior of individuals which resulted in the worst individual outcomes for all players.

Behavioral-analytic research of cultural selection and the complexity of cultural Phenomena / La Investigación Analítico-Conductual de la Selección Cultural y la Complejidad de los Fenómenos Culturales

Several conceptual and experimental studies on the behavioral-analytic literature have suggested that it is possible to address B.F. Skinner's cultural selection phenomena through heuristic approaches. The concepts of metacontingency, interlocking behavioral contingencies (IBCs), cultural milieus, aggregate products, cultural consequences and receiving systems are useful tools for the cultural level of analysis. This paper reviews Glenn and Malott's (2004) perspective on complexity in organizations and suggests complementing it with Norbert Elias' sociological approach, in which increasing complexity in a social system results in (a) increasing conflicts between individual and cultural consequences, (b) greater concurrency of the contingencies that affect the behavior of each member of the group, and (c) the specialization of the functions performed by each participant in the system. We suggest that the more complex a social system is, the more social mediation is necessary to select the IBCs and the more differentiated the cultural consequences from the aggregate product.

Varios trabajos conceptuales y experimentales en la literatura analítico-conductual han considerado que es posible hacer frente a los fenómenos sugeridos por BF Skinner como selección cultural de manera heurística. Los conceptos de metacontingencia, contingencias conductuales entrelazadas (CCE), entorno cultural, producto agregado, consecuencias culturales y sistema receptor son herramientas útiles para aplicar el nivel cultural de análisis. El artículo examina las sugerencias de Glenn y Malott (2004) sobre la complejidad en las organizaciones y sugiere que ésta podría ser complementada por las dimensiones: (a) conflicto entre las consecuencias individuales y culturales; (b) la concurrencia de las contingencias que afectan el conducta de cada miembro de un grupo, (c) la especialización de las funciones ejecutadas por cada participante en el sistema. Sugerimos que cuanto más complejo es un sistema social, más mediación social es necesario para seleccionar las CCEs y más diferenciadas son las consecuencias culturales del producto agregado.
