The Effect of Social Contingencies on Near Miss Ratings n Blackjack

Hull, Ashley 01 August 2013 (has links)
Previous studies on gambling behavior have identified the phenomenon known as a `near miss.' This phenomenon has been shown to increase gambling behavior while engage in various gambling scenarios like blackjack and slot machine play. The current study sought to show a correlation between social contingencies and verbalized near miss ratings between two players. One participant in the study served as a confederate and was aware of all experimental variables. Three other participants engaged in the study. Following each hand of play both the confederate and the participant verbalized a rating of how closely they felt they were to winning from 1 to 9. Results from the study were erratic and inconclusive. Despite getting unanticipated results, merit to the study still exists in paving the way to study the social effects of verbalizing near miss ratings.

The cultural practices are algokept, according to Skinner, for its consequences for the group: the aggregated outcome among them. Experiments concerning the selection of such practices, rare in the behavior analysis, have been conducted for sociologists and social psychologist, as Wiggins. In the present work was investigated the possibility to modify the way that the participants of an experimental group distributetheir profit in a gamblegame- equall distributions or not - manipulating only the aggregatedoutcomesproducedby the group- the successor failurein the game.Eight colleges students distributed in two groups had participated; they had passed for the same experimental conditions in different sequences. The change of experimental condition depended on stability in the performance of the group. In a gamble game each member of the group bet tokens and with their colleagues debated and choose a possible resultoIf the bet was announced as correct, the group received in return the double of the investment, if the bet was incorrect, the group received half from the bet tokens. The result was announced by the experimenter and depended (without the knowledge of the participants) on the way as the group had distributed the tokens among the members in the previous turnoIn the experimental condition "A", ifthe distribution ofthe tokens were equall among ali its members in the previous turn, it was announced as "correct". In condition "B" the success was a result of an unequall division. The results show that the procedure was effective in modifying the way as the integrants of the groups distribute the gotten resources. The results had aiso shown that the change in the performance of the participants was more difficult when the success was followed by unequall distribution of the bets outcomes. Verbal reports collected at the end of the experiment indicate that no participant was capable to verbally describe the variable responsible for the success in the task. It is discussed the possibility to interpret the manipulations made in the group and its results in terms of the metacontigencies notion / Para Skinner o comportamento humano é determinado por variáveis filogenéticas, ontogenéticas e culturais, segundo o modelo de seleção por conseqüências. Também as práticas culturais são mantidas, segundo Skinner, pelas suas conseqüências para o grupo: entre elas, os resultados agregados que produzem. Experimentos acerca da seleção de tais práticas, raros na análise do comportamento, têm sido conduzidos por sociólogos e psicólogos sociais, como Wiggins. No presente trabalho investigou-se a possibilidade de alterar o modo como os participantes de um grupo experimental distribuíam seus ganhos em umjogo de apostas - distribuições igualitárias ou não - manipulando somente os resultados agregados produzidos por este grupo - o sucesso ou fracasso no jogo. Participaram oito universitários distribuídos em dois grupos, que passaram pelas mesmas condições experimentais em diferentes seqüências. A mudança de condição experimental dependia de estabilidade no desempenho do grupo. Num jogo de apostas cada participante do grupo apostava fichas e com seus colegas debatia e escolhia um resultado possível. Se a aposta fosse anunciada como certa o grupo recebia de volta o dobro do investimento feito, se a aposta fosse errada, o grupo recebia metade das fichas apostadas. O resultado era anunciado pelo experimentador e dependia (sem o conhecimento dos participantes) do modo como o grupo havia distribuído as fichas entre os membros na jogada anterior. Na condição experimental "A" se a distribuição das fichas era igualitária entre todos os seus integrantes na jogada anterior a aposta seguinte era anunciada como certa. Na condição "B" acerto seguia uma divisão desigual. Os resultados mostram que o procedimento foi eficaz em alterar o modo como os integrantes dos grupos distribuíam os recursos obtidos. Os resultados mostraram também que a mudança no desempenho dos participantes foi mais difícil quando ganhar era seguido de distribuição desigual dos resultados das apostas. Relatos verbais coletados ao final do experimento indicam que nenhum participante foi capaz de descrever verbalmente as variáveis responsáveis pelo sucesso na tarefa. Discute-se a possibilidade de interpretar as manipulações feitas e seus resultados em termos da noção de metacontingências
