Ecología del miedo by Patiño Giovanny Giovanny on Prezi

Fantino and Case found that subjects would respond to produce the stimulus associated with reinforcement but would not respond to produce the signal for nonreinforcement, even though they both contain the same amount of information i. It would be interesting to know if giving an animal a large number of skill tasks in which getting close to success represents a higher probability of success might alter an animal’s avoidance of near-hit outcomes in tasks in which skill plays no role.

That is, the contrast or good news associated with the terminal link stimulus assumes that the suboptimal initial link alternative must be of lesser value than the optimal alternative.

In addition to what gamblers describe as the pleasure of gambling, most public gambling e. Estudio de caso 5: Failure to support the Allais paradox.

Drug and Alcohol Dependence97 Thus, when humans engage in commercial gambling they are making suboptimal choices, however, in spite of the poor odds of winning over losing, it is possible for one to justify the behavior in terms of the excitement or pleasure derived from the activity.


Harvard University Press, Opyimo. Thus, although there may be some procedural differences between the pigeon suboptimal choice task and human commercial gambling, the important elements of the two are quite similar as supported by the finding that a modified version of the pigeon task is able to distinguish human gambler from nongamblers Molet et al. Esto se traduce en que la curva propuesta por Poblete optino al. Surprisingly, although optimal foraging theory suggests that animals should be sensitive to the overall probability of reinforcement, the results of many experiments suggest otherwise.

Journal of Gambling Studies15 Boletin SEA dorrajeo 1 Thus, almost all pecking is reinforced. Andersen A, Majer J, Formicidae in the Monte Desert: Commercial gambling systems sometimes take advantage of the perceived value in coming close to winning by programming machines to provide more of these near hits to encourage further play.

Similarly, research with humans has found that problem gamblers show reduced sensitivity to aversive conditioning Brunborg et al. Journal of the Experimental Analysis of Behavior, Thus, impulsive individuals require that the delay to the larger amount forrsjeo reinforcement be relatively short before they will prefer it and for them the slope of the discounting function would be relatively steep.

Of course, it is possible that if the probability of reinforcement associated with low probability high payoff stimulus was reduced still further, the pigeons’ choice may have reversed to become optimal. That is, they now showed a strong preference for the alternative associated with 3 pellets per trial.


Furthermore, oltimo relative probability of reinforcement associated with the two initial link alternatives appears to be relatively unimportant.

Impulsivity and Pathological Gambling: ABSTRACT Human gambling generally involves taking a risk on a low probability high outcome alternative over the more economically optimal high probability low outcome alternative not gambling. In all of the research cited, the probability of reinforcement was manipulated, however, when humans gamble, the alternatives generally involve different magnitudes of reinforcement rather than different probabilities of reinforcement.

Do humans, like pigeons, show suboptimal choice? Under these conditions the pigeons showed a very strong preference for the discriminative stimulus alternative. Del mismo modo, los individuos adultos presentaron una preferencia significativa por S.

In fact, we have found that for pigeons, if the suboptimal outcome is delayed, relative to the optimal outcome, the pigeons begin to choose optimally Zentall and Stagner, b, Exp.

The reasoning is as follows:
