The human brain is able to learn, generalize, and predict crossmodal stimuli which help us to understand the world around us. Some characteristics of crossmodal learning inspired some computational models but most of the solutions only go as far as to implement strategies for early or late crossmodal fusion. In this paper, we propose the use of two mechanisms from behavioral psychology to enhance the capabilities of a deep adversarial network to learn crossmodal stimuli: the unity assumption modulation and expectation learning. We use real-world data to train and evaluate our model in a set of experiments and demonstrate how these mechanisms affect the learning behavior of the model and how they contribute to making it learn crossmodal coincident stimuli. Our experiments show that the addition of these two mechanisms modulates the crossmodal binding capabilities of the model and improves the learning of unisensory descriptors.
