A influência do álcool na recombinação de repertórios

Abstract

The consumption of alcoholic beverages occurs recurrently in different regions and cultures so that the beginning of consumption of this substance occurs in different age groups and lasts for different periods of the subject's life. In this sense, the objective was to study the effects of alcohol consumption, on processes such as creativity and problem solving, in addition to putting into analysis the experimental model of recombination of repertoires. The experimental subjects consisted of fourteen male albino rats (Rattus norvegicus) of the Wistar lineage, with no previous experience in the activities of digging and climbing. The procedure consisted of four phases: 1) four habituation sessions, where the animals had access to the Froot Loops cereal; 2) recombination pre-test, where all animals were placed for ten minutes in the problem situation; 3) training of the prerequisite responses, where the digging and climbing responses were modeled; and 4) test, where the animals were again subjected to a problem situation. It is noteworthy that before phase 1, the experimental subjects were randomly divided into two groups: Control Group - CG and Acute Alcohol Group - GAA. The administration of the acute alcohol dose in GAA occurred orally via gavage, in the dose of 3g / kg of 50% alcohol, 30 minutes before the test session. In the Control Group, 1ml / kg of water was administered orally via gavage 30 minutes before the test session. It was observed that in the habituation phase the CG consumed, on average, 7.64 (SD = 5) Froot Loops® per session and the GA consumed, on average, 10.32 (SD = 3.63) cereals per session. During the pre-test session, none of the animals solved the problem situation. Regarding the training of climbing and digging responses, it was found that the CG reached the learning criterion in 4 sessions and the GA reached the learning criterion, on average, 4.57 (SD = 0.967) sessions, being that in the response of digging the CG reached the learning criterion, on average, in 15.43 (SD = 3.259) sessions and the GA reached the learning criterion, on average, in 15.71 (SD = 2.870) sessions. Regarding the test phase, it was observed that six animals in the GC emitted the cavar-scalar response chain, with only three animals from the GAA emitting the expected response. It is observed that the GAA group presented a lower resolution rate in the test session, when compared to the CG, and it can be assumed that this difference occurred due to an influence of the acute use of alcohol during the test session.
