In situations of ambiguity, where a correct decision is not clear, people make random decisions. In situations with emotional meaning, the answers dont follow this pattern. The present study aims to provide an overview of an overestimation in the decisions of people in situations of emotional ambiguity, between fear, disgust and happiness. 33 women and 45 men aged between 18 and 25 years were given several mosaics at the computer where 36 different images were shown. These mosaics, or Walls of Scenes were either clear (8 images from a category, and 28 from the other) or ambiguous (18-18 images). The affective category contained images of disgust, fear and happiness (paired negative and positive emotion, mosaics of images of disgust and happiness and mosaics of images of fear and happiness) and neutral pictures (mushrooms and flowers) .The main results of the study show an overestimation of images with affective meaning compared to neutral images in ambiguous situations. The probands rated the neutral ambiguous Wall of scenes with a random pattern (50% mushrooms, 50% flowers), but the evaluation of affective pictures was higher in the direction of the negative emotion (disgust and fear when both were paired with happiness scenes).As a further result, there was a correlation between disgust sensitivity and the overestimation of disgust in situations of affective ambiguity.
