The Effects of Fines on Cooperation in a Four-Person Prisoner’s Dilemma Game

Morford, Zachary H. 08 1900 (has links)
Cooperation is an important area of investigation for behavior analysis. The prisoner’s dilemma game (PDG) provides a useful scenario for studying cooperation in a behavior analytic paradigm. The PDG can be coupled with the concept of the metacontingency to investigate how various contingency arrangements support and promote cooperation in a group. Players in this experiment participated in a PDG and, in some conditions, were given the ability to fine other players but could not talk. The goal of this experiment was to investigate how players’ ability to fine one another affected the players’ patterns of cooperation, and whether fining itself was affected by the addition of a shared group consequence. The data show that participants cooperated in some conditions, but the fines did not seem to affect players’ rates of cooperation.

Assessment of a metacontingency instructional package for a rehabilitation day training classroom

Hargraves, Toni Danielle 01 May 2015 (has links)
AN ABSTRACT OF THE THESIS OF Toni Hargraves, for the Master of Science degree in Behavior Analysis and Therapy, presented on April 2015, at Southern Illinois University Carbondale. TITLE: ASSESSMENT OF A METACONTINGENCY INSTRUCTIONAL PACKAGE FOR A REHABILITATION DAY TRAINING CLASSROOM MAJOR PROFESSOR: Dr. Ruth Anne Rehfeldt The following study evaluated the effects of a metacontingency instructional package on interlocking behaviors by measuring the products produced by the interlocking behaviors of four adults attending a specialized rehabilitation center and working to obtain financial gain and community inclusion. The package was a manipulation of the environment of a day training classroom by incorporating a program where contingencies were available on an interrelated level and targeted as many individuals as possible to provide the largest societal gain. For 3 adults with mild to severe intellectual disabilities, task completion increased above task completion averages observed during baseline conditions where only individualized tasks were presented. For all participants, cooperative behaviors were only observed in the condition where tasks were interrelated with tasks of peers and returned to baselines levels once the package was removed. Producing the changes at this level may be socially relevant due to the potential gains of the participants, potential gain of the rehabilitation setting in relation to funding for productivity results, and the potential gain to the overall community through increased social skills of individuals who interact in that setting.

An examination of the metacontingency utilizing activities with embedded interlocking contingencies to promote social interactions

Fults, Megan Rae 01 May 2016 (has links)
The current investigation examined the effectiveness of a metacontingency package in two experimentations. In experiment one, the metacontingency was utilized by embedding activities with interlocking behavioral contingencies to examine its effectiveness on reciprocal social interactions in two females diagnosed with an Intellectual Disability. Results demonstrated an increase of the dependent variable by the metacontingency activities. The results of experiment one were the premise for experiment two, which was to examine whether the metacontingency activities that were effective in increasing reciprocal social interactions were an effect of the metacontingency or an effect of engaging in an activity together. Experiment two utilized two activity types, parallel and metacontingency activities, to determine their relative effect on self-talk behavior, reciprocal social interactions, and conversational units in two males diagnosed with an Intellectual Disability. Results suggested that there were no relative effects demonstrated by the two activity types on self-talk behavior, however results demonstrated an increased effect by the metacontingency activities relative to the parallel activities on reciprocal social interactions and conversational units.

An Exploration of Cooperation during an Asymmetric Iterated Prisoner's Dilemma Game

Lopez, Carlos Ramiro 08 1900 (has links)
Researchers investigated how the contingent delivery of a cultural consequence on target culturants in an asymmetric iterated prisoner's dilemma game (IPDG) affected players' choices. The asymmetric IPDG creates an analogue to income disparities created by wage gaps and other cultural practices that create wealth inequalities between different members of the population and allows researchers to explore how these inequalities affect cooperation between players. Six undergraduate students divided into three dyads participated in an ABABCDCD reversal design. An asymmetric IPDG was arranged in Condition A and C such that one player received a greater number of points regardless of the second participants' selections - analogue to contingencies that produce income inequalities from wage gaps. In Condition B and D, a metacontingency was arranged such that delivery of a cultural consequence (CC; bonus points equally distributed among the dyad) was contingent on the oscillating production of target aggregate products (AP) across two consecutive cycles. When participants' coordinated responding and contacted the target AP→ CC relation, the wage gap was reduced. However, individual contingencies are in direct competition for the "wealthier" player, reducing the probability of cooperative responding. Results showed the CC selected certain oscillations between target APs resulting in a decrease of a point disparity between the players while also establishing equal points between the players during certain conditions.

Analyzing Contingencies of Behavioral and Cultural Selection

Hunter, Chad S. 08 1900 (has links)
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) conditions, 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.

Selecting Variability in Interlocking Behavioral Contingencies

Urbina, Tomas, III 12 1900 (has links)
The current study explored how the variability or lack thereof in interlocking behavioral contingencies (IBC) may be brought under contextual control. Four undergraduates (two dyads) students participated in the current study. Dyads were instructed to play a game on a computer screen with the goal to earn as many "Congratulations" as possible. An ABABAB reversal design was used. A Lag 1 schedule of cultural consequence delivery for IBC topography was set in the variability (VAR) condition. During the repeated (REP) condition only one IBC topography was reinforced. For one of the two dyads, the variability of IBC topography was brought under contextual control. It is important to explore the behavioral processes at the cultural level to understand prediction and control of cultural phenomena.

Análogos experimentais de metacontingências: o efeito da retirada da conseqüência individual

Brocal, Andréa Lopez 20 May 2010 (has links)
Made available in DSpace on 2016-04-29T13:18:17Z (GMT). No. of bitstreams: 1 Andrea Lopez Brocal.pdf: 1248063 bytes, checksum: 8b54223469e71a5d5107b5fb0b6a04f8 (MD5) Previous issue date: 2010-05-20 / The inclusion of the so-called cultural phenomenon as the object of interest or study of behavior analysis begins when Skinner describes human behavior and aspects which are characteristics of social relations. Other researchers in the behavior analysis interested in these studies, present in their studies (researches) the concept of metacontingency as a conceptual tool to the comprehension of cultural phenomenon. A number of attempts to produce analogous of metacontingency in an experimental environment have been made, and proceeding with these efforts the question which is the aim of the present study is whether the suspension of the consequences which are individually relevant, despite not having effects on the interlocking, would also have an effect on the selection of / by metacontingency. In other words, what would happen to the selected interlocking, if there was a suspension of contingencies to the operant behavior after the selection of / by metacontingencies? In order to do that, two experiments were designed. Experiment 1 was conducted by 3 (three) phases and the principal manipulation was removed from the individual consequence after the metacontingency was selected. The second experiment or Controlling Experiment, which did not include the selection phase and the strengthening of the operant behavior, in which only a determined relation between the participants and their consequent aggregated product were sequenced. The results indicated that in Experiment 1 there was not the simultaneous maintenance of the individual and cultural consequence. Nonetheless, it can be stated that both of them, at their own pace, showed to be under control of the programmed consequence. The Experiment 2 shows that independently of the selection of a specific operant behavior there was the selection of the IBCs and their aggregate product by cultural consequences. Results indicate that, despite of the operating selection being programmed, the aggregated product may emerge and the programmed cultural consequence may occur on the coordination as a way to strengthen it. Due to some circumstances which have arisen in Experiment 1, it is suggested that its replication with some modifications to determine the effects of the suspension of differential consequences of contingencies operating on IBCs / A inclusão dos fenômenos ditos culturais como objeto de interesse ou estudo da análise do comportamento tem inicio quando Skinner descreveu comportamento humano e aspectos característicos das relações sociais. Desse interesse participam outros estudiosos da análise do comportamento que em seus estudos tomaram o conceito de metacontingência como ferramenta conceitual para compreensão dos fenômenos culturais. Diversas tentativas de se produzir análogos de metacontingência em ambiente experimental tem sido feitas e dando continuidade a esses esforços a pergunta que dirigiu o presente estudo foi se a suspensão de conseqüências que são individualmente relevantes, mas que não são necessárias para a produção de produtos agregados, teria efeitos sobre os entrelaçamentos que envolvem a seleção de / por metacontingências. Ou seja, o que ocorreria com CCEs e seus produtos agregados, selecionados por conseqüências culturais, quando ocorre a suspensão de contingências para comportamentos operantes associadas (mas não necessárias) a tais produtos agregados? Para tanto foram delineados dois experimentos, o Experimento 1 foi constituído por 3 fases e a principal manipulação foi a retirada da conseqüência individual após selecionada uma metacontingência. No segundo experimento suprimiu-se a fase de seleção e fortalecimento do comportamento operante, nele somente uma determinada relação entre os participantes e seu conseqüente produto agregado eram consequenciados. Os resultados indicaram que no Experimento I não houve a manutenção simultânea da conseqüência individual e da cultural, embora seja possível afirmar que ambas as conseqüências programadas tiveram efeito selecionador. No Experimento 2 demonstrou-se que independente da seleção de um comportamento operante específico houve a seleção da contingências comportamentais entrelaçados e seu produto agregado por conseqüências culturais. Conclui-se que a despeito da seleção operante ser programada, o produto agregado pode emergir e a conseqüência cultural programada pode incidir sobre a coordenação de maneira a fortalecê-la. Devido a algumas circunstâncias que se apresentaram no Experimento 1, sugere-se sua replicação com algumas modificações para verificar-se os efeitos da suspensão de conseqüências diferenciais de contingências operantes sobre CCEs

Efeitos de dois procedimentos de suspensão da dependência entre contingências comportamentais entrelaçadas e eventos culturais / Effects of two procedures of dependency suspension between interlocked behavioral contingencies and cultural events

Marques, Natalia Santos 17 June 2016 (has links)
O presente estudo teve como objetivo investigar o papel da dependência/contingência entre um efeito programado no ambiente (EC) e um padrão coordenado de espaçamento entre as respostas de três participantes (CCE), em um procedimento de culturante livre e delineamento experimental intrassujeito. Foram realizados 3 experimentos, dos quais participaram 24 estudantes universitários, divididos em 8 tríades. A tarefa consistiu no clique sobre uma imagem apresentada em uma tela de computador. Foram programados ECs para um dado espaçamento entre os cliques dos participantes. Nos Experimentos 1 e 2, adicionalmente, foram programadas consequências individuais para o clicar, e as manipulações na relação de dependência entre CCEs e ECs foram avaliadas a partir de uma linha de base operante. O Experimento 1 isolou os efeitos da dependência do EC dos efeitos de sua intermitência, frequência e distribuição, comparando condições de apresentação contingente do EC (em intervalos variados - VI) e condições de apresentação não contingente desse evento (em intervalos de tempo variado - VT). O Experimento 2, por sua vez, comparou os efeitos da apresentação de ECs em VT com os efeitos da suspensão da apresentação desse evento (extinção convencional EXT). O Experimento 3, finalmente, comparou os efeitos de EXT e VT, sem que houvesse outra contingência programada, adicionalmente à contingência CCE-EC (metacontingência). Os resultados dos três experimentos evidenciaram o estabelecimento e manutenção de CCEs em função dos esquemas de apresentação do EC. Comparações entre esquemas contingentes e não contingentes demonstraram a importância da dependência/contingência do EC para o estabelecimento e manutenção sistemática de CCEs. Comparações entre EXT e VT evidenciaram que a apresentação não contingente de ECs gera efeitos assistemáticos na manutenção de CCEs. Enquanto as condições de EXT geraram rápida extinção das CCEs, as condições de VT geraram efeitos diversos: ora extinção, ora manutenção de CCEs por longos períodos. Foram observadas similaridades entre processos de seleção, manutenção e extinção de operantes e de culturantes. Em conjunto, os resultados desse estudo fortalecem e estendem as informações já produzidas sobre relações funcionais entre termos de uma metacontingência e sobre as similaridades entre processos de evolução de operantes e de culturantes. Adicionalmente, esse estudo dá um passo além na investigação das unidades mínimas e das condições necessárias ao estabelecimento e manutenção de culturantes. Aponta-se para a necessidade de maiores investigações sobre os efeitos de diferentes esquemas de apresentação do EC e maior refinamento do conceito de metacontingência, de modo a evidenciar a independência entre contingências operantes e metacontingências e, assim, orientar programações experimentais que possibilitem análises mais efetivas para a compreensão da contingência programada entre CCEs e ECs / This study aimed to investigate the role of dependency/contingency between a programmed environmental effect (CE) and a coordinated pattern of spacing between responses of three participants (IBC), in a free culturant procedure and a single-subject experimental design. Were performed three experiments, participated 24 undergraduate students divided into 8 tryads. The task consisted in clicking on an image presented on a computer screen. Were programmed CEs contingent to a specific spacing pattern between participants clicks. Also, in experiments 1 and 2 were programmed individual consequences to clicking, so the manipulations in the dependency relation between CEs and IBCs were analyzed upon an operant baseline. Experiment 1 isolated the effects of CE dependency from its intermittency, frequency, and distribution effects, comparing conditions of contingent CEs presentations (in variable intervals VI) and noncontingent CEs presentations (in variable time VT). Experiment 2, in turn, compared the effects of CEs presentations in VT, and CEs suspension effects (conventional extinction EXT). Experiment 3, finally, compared effects of EXT and VT, with no other programmed contingency besides the CCE-EC contingency. The results of the three experiments showed establishment and maintenance of IBCs as a function of CEs schedules. Comparison between contingent and noncontingent schedules of CEs presentations demonstrated the importance of dependency/contingency of CE for establishment and systematic maintenance of IBCs. Comparison between EXT and VT demonstrated that noncontingent presentation of CEs generates unsystematic effects in IBCs maintenance. While EXT conditions generated rapid extinction effects, VT conditions generated diverse effects: sometimes extinction, sometimes maintenance of IBCs for long periods. Similarities were observed between the processes of selection, maintenance, and extinction of operants and culturants. As a whole, these results strengthen and extend the amount of information about functional relations between metacontingency units and about similarities between operant and culturant evolution. Additionally, this study goes a step further into the investigation of minimal units and necessary conditions for the establishment and maintenance of culturants. It is pointed out the necessity of further investigation on the effects of different schedules of CEs presentations and further refinement of the metacontingency concept, making evident the independency between operant contingencies and metacontingencies, thus, guiding experimental arrangements that enable more effective analysis for understanding the contingency scheduled between IBCs and CEs

Exploring the Effects of Cultural Consequences Identified through a Ranking Task on the Interlocking Behavioral Contingencies of Ethically Self-Controlled Responses with Participants with Pre-Existing Relationships

Elwood, Chelsea Christina 05 1900 (has links)
This study explored the effects of cultural consequences identified through a ranking task on the selection of interlocking behavioral contingencies and aggregate products constituting ethically self-controlled responses when participants had pre-existing relationships. Two experiments were conducted to explore these effects. Experiment 1 had two triads of three participants each recruited from a university-based autism center. Experiment 2 had three triads of three participants each; participants in Triads 3 and 4 were recruited from a university-based rock-climbing club while participants in Triad 5 were recruited from the same university-based autism center as in Experiment 1. All participants were exposed to a task that involved choosing odd or even rows from a matrix displayed throughout the experimental session. Individual contingencies were programmed in all conditions while metacontingencies were programmed in some conditions. Participants selected the topography of the cultural consequence through a pre-experimental ranking task prior to the onset of the experimental session. A change was made to the experimenter's verbal behavior in all operant and metacontingency conditions for Experiment 2. The results of both experiments indicate that identification of the cultural consequence through a ranking task with participants having pre-existing relationships did have an effect on the continued selection of the cultural consequence across all triads with quicker selection occurring during Experiment 2. This study extends the current literature on ethical self-control and provides new procedures and designs to further understand the variables involved in the selection of cultural consequences when there is competition with an immediate operant consequence.
