Memory is not a perfect processor, and is affected by many factors. 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. 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. Non-declarative, or implicit, memory is the unconscious storage and recollection of information. Declarative memory is usually the primary process thought of when referencing 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. Under declarative memory resides semantic and episodic memory. ĭeclarative, or explicit, memory is the conscious storage and recollection of data. Finally, the function of long-term memory is to store data through various categorical models or systems. The working memory also retrieves information from previously stored material. Information in the form of stimuli is encoded in accordance with explicit or implicit functions by the working memory processor. Working memory serves as an encoding and retrieval processor. The sensory processor allows information from the outside world to be sensed in the form of chemical and physical stimuli and attended to various levels of focus and intent. Memory is often 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. Memory loss is usually described as forgetfulness or amnesia. If past events could not be remembered, it would be impossible for language, relationships, or personal identity to develop. It is the retention of information over time for the purpose of influencing future action. Memory is the faculty of the brain by which data or information is encoded, stored, and retrieved when needed.
