Forgetting can drive me crazy (literally), but it doesn’t neseccarily mean a physiological or mental issue:orgetting also helps to reconcile the storage of new information with old knowledge.
Memory performance is usually related to the active functioning of three stages. These three stages are:
memory is understood as an informational processing system with explicit and implicit functioning that is made up of a sensory processor, short-term (or working) memory, and long-term memory
Working memory serves as an encoding and retrieval processor.
Explicit and implicit functions of memory are also known as declarative and non-declarative systems.
Declarative, or explicit, memory is the conscious storage and recollection of data.
Under declarative memory resides semantic and episodic memory.
Semantic memory refers to memory that is encoded with specific meaning, while episodic memory refers to information that is encoded along a spatial and temporal plane. Declarative memory is usually the primary process thought of when referencing memory.
Non-declarative, or implicit, memory is the unconscious storage and recollection of information.
An example of a non-declarative process would be the unconscious learning or retrieval of information by way of procedural memory, or a priming phenomenon. Priming is the process of subliminally arousing specific responses from memory and shows that not all memory is consciously activated, whereas procedural memory is the slow and gradual learning of skills that often occurs without conscious attention to learning.
The ways by which information is encoded, stored, and retrieved can all be corrupted.
