The aim of this study is to investigate the influence exerted by the subliminal effect in decision tasks in a scenario of stock acquisition through the experimental approach. For this purpose, using the simulation of investment, an experiment which considered two types of decision on whether to purchase the stocks (buy and not buy) was conducted. This study included 31 professionals in a Neuroscience laboratory, in which each target was preceded by a subliminal stimulus lasting 17 minutes, using a mask bearing words typical of Economics (positive / negative) randomly categorized. The proposal of the research was to analyze the positive or negative effects on decisions. The experimental results were statistically analyzed using the techniques Chi-square and ANOVA. The analysis the results suggest that when the subject does not know the company, his/her decision can indeed be influenced, showing that lack of knowledge permits influence of words. Our findings suggest that subliminal effects influence decisions when the subjects are not familiar with the companies, because the subjects were affected in our experiment.
