Psychology and Visual Design
Do designers need to understand psychology?
Psychology is necessary for visual design, although not to the scientific extent it can go to. The way humans process every bit of visual information is in the brain, which determines how they react to it, whether it is a positive or negative experience. Hence, to determine how visual design works best, we have to first understand how the brain works. This helps to predict which visual elements such as shapes, colour and size will result in which type response from people. For designers, it is crucial that they’re designed produces the most positive effect.
However, psychology studies the brain at a much deeper level than which a lot of design works off and hence a great visual designer would not necessarily have to understand psychology to an expert degree, however, a good level of knowledge would be highly beneficial.
