Implicit cognition describes the fascinating learning, memory, and performance processes which take place without the subject's explicit awareness. A well known example is patients under anaesthetic who, without being able to verbally recall the surgeons' conversation, do show some retention of the conversation. How much of what we know has been learned implicitly? How much of our problem-solving abilities are founded on unconscious processes? Researchers disagree widely over the inmportance, and even the existence, of implicit cognition as an issue in human psychology. This book brings together several internationally known authors with conflicting views on the subject, providing a lively and informative overview of this controversial area.
