Explicit and Implicit Memory

When we normally think of memory, we are thinking of explicit memory. Memory techniques and most of the posts on memory in this blog are concerned with explicit memory. Implicit memory refers to memory that occurs without your consciousness awareness. Implicit memory covers a wide range of activities. Classical conditioning, habit learning, emotional memory, procedural and motor memory typically are implicit. So implicit memory involves both maladaptive behaviors, such as bad habits and addiction, but it is also involved in the development of optimal strategies in skill acquisition. Implicit learning could also be helpful for amnesiacs and Alzheimer’s patients.1

Theorists have wondered why we have two types of memory. Although theorists wonder about this, it is nice to have a type of memory that requires little or no consciousness. Although consciousness might not be required, trials or repetitions are required. For example, classical conditioning in which a conditioned stimulus, say a bell, is paired with an unconditioned stimulus, say food, before the sound of the bell alone will cause you, or a dog, to salivate. Similarly habits take repetitions to develop, and procedural and motor skills can take a great deal of practice to perfect. On the other hand, emotions, depending on the strength of the emotion, can be learned quite rapidly.

I think it is obvious why we have explicit memory. Explicit memory involves consciousness. Had we only implicit memory we would be acting like Zombies, behaving and learning with little or no understanding as to why. So it is understandable that most educational practices and most of the Healthymemory Blog posts involve explicit memory. But we should be thankful for these implicit memory processes. Consider how burdensome it would be if all memories were explicit.

We do need to learn more about implicit memory. Much athletic and artistic performance is a matter of practicing to the point where skills become automatic. Usually performance falters when the performer or athlete starts to think about what they are doing. Implicit memory also offers a path into the memories of those for whom explicit memory has been lost such as Alzheimer’s patients and other suffering from traumas to the medial temporal lobes.
