Implicit memory refers to memories of which people are not consciously aware, but which can affect subsequent performance and behavior. Skills that operate automatically and without thinking, such as jumping out of the path of an automobile coming toward us as we walk down the side of a road, are stored in implicit memory. Similarly, a feeling of vague dislike for an acquaintance, without knowing why are have that feeling, may be a reflection of implicit memories.
Implicit memory means a memory for previously learned activities or material that one apparently is not conscious of. Unlike explicit memory it is often largely intact in people with amnesia.
