Implicit cognition

Implicit cognition refers to unconscious influences such as knowledge, perception, or memory, that influence a person's behavior, even though they themselves have no conscious awareness whatsoever of those influences.

Implicit cognition is everything one does and learns unconsciously or without any awareness that one is doing it. An example of implicit cognition could be when a person first learns to ride a bike: at first they are aware that they are learning the required skills. After having stopped for many years, when the person starts to ride the bike again they do not have to relearn the motor skills required, as their implicit knowledge of the motor skills takes over and they can just start riding the bike as if they had never stopped. In other words, they do not have to think about the actions that they are performing in order to ride the bike. It can be seen with this example that implicit cognition is involved with many of the different mental activities and everyday situations of people's daily lives. There are many processes in which implicit memory works, which include learning, our social cognition, and our problem solving skills.

Implicit cognition was first discovered in the year of 1649 by Descartes in his Passions of the Soul. He said in one of his writings that he saw that unpleasant childhood experiences remain imprinted in a child's brain until its death without any conscious memory of it remaining. Even though this idea was never accepted by any of his peers, in 1704 Gottfried Wilhelm Leibniz in his New Essays Concerning Human Understanding stressed the importance of unconscious perceptions which he said were the ideas that we are not consciously aware of yet still influence people's behavior. He claimed that people have residual effects of prior impressions without any remembrance of them. In 1802 French philosopher Maine de Biran in his The Influence of Habit on the Faculty of Thinking was the first person after Leibniz to systematically discuss implicit memory stating that after enough repetition, a habit can become automatic or completed without any conscious awareness. In 1870 Ewald Hering said that it was essential to consider unconscious memory, which is involved in involuntary recall, and the development of automatic and unconscious habitual actions.
