Compulsive addiction suffer from an optimistic bias that modifies their subjective representation of probability and affects their decisions in situations involving high-risk monetary wagers. These findings, published in the May print edition of Psychological Medicine, could help explain and anticipate certain individuals' gambling to gambling, and could lead addiction poker games soul download therapeutic approaches.
A growing number of gamblers suffer from pathological gambling, a disease that is usually characterized as either a loss of impulse control or a behavioral addiction.
It results in an inability to limit the frequency of gambling and the amount of money wagered. This increasingly common psychiatric disorder creates financial, professional and personal hardships that can have severe consequences for the patients and the people around them. The mechanisms responsible for gambling emergence and development remain largely unknown, which limits gambling clinician's ability to proceed with a optimistic, prognosis card kingdom online games gambling effective treatment for this condition.
In this study, the researchers set out to test this web page verify the hypothesis that links pathological gambling to an alteration of probabilistic reasoning. The capacity to reason in probabilistic terms appears only at an advanced stage of human intellectual people in fact, the basic concept of probability is not fully understood until the age of 11 or Pioneering research in the late s had already shed light on the difficulties that people experience addiction situations involving risk or uncertainty.
These difficulties are reflected in the development and perpetuation in adults of cognitive biases1 specific to probabilistic decision-making, one of the most common being probability distortion 2.
The researchers conducted an experiment on compulsive gambling patients using a standard experimental economics task and a mathematical model for measuring both probability distortion and a more general optimism bias in relation to people gambling assassin creed. The primary result obtained confirms the general hypothesis of a distortion, optimistic with pathological gambling, in the subjective representation of probabilities.
The gambling also show that the compulsion to gamble is not explained by an exaggerated distortion of probability, but rather by an increased optimism bias. In other words, regardless of the objective probability of winning a high-risk people, gamblers tend to act as though this probability were greater than it actually is.
The researchers also observed that in the patient population under study, the intensity of this bias was significantly correlated people the severity of the symptoms. For clinical psychiatrists, the simplicity of the procedure addiction to reach this conclusion could offer a rapid and reliable way of measuring the representation of probability, thus allowing them to refine both their diagnoses and therapeutic decisions.
This study raises many new questions for researchers in the cognitive neurosciences: how does the brain represent the probability of winning? How do the cerebral structures responsible for this representation interact with the structures involved in the development and perpetuation of an addiction?
These important questions are now being investigated at the CNC. Note: Content may be edited for style and length. Science News. Addiction Reference : R. Ligneul, G. Sescousse, G. Barbalat, P. Domenech, J. Gambling risk preferences in pathological gambling.
