Episodic memory is the name given to the capability to consciously remember personally experienced occasions and conditions. It is considered one of the foremost psychological (cognitive) capacities enabled by the brain. In the prototypical act of exercising the capacity of episodic memory one could remember a current trip to Paris, mentally reliving occasions that occurred there, within the mind’s eye seeing again the locations visited, sights seen, sounds heard, aromas smelled, and people met. Memory is an umbrella term that covers a selection of different types of acquisition, retention, and use of habits, expertise, knowledge, and experience. Those that examine memory have found it helpful to assume that completely different forms of studying and memory are subserved by totally different memory systems--organized collections of neurocognitive elements that work together to perform capabilities that different collections of parts can't perform, or can not perform as effectively. An essential objective of analysis has to do with the identification of these memory programs, specification of their properties, and delineation of the character of the relations amongst them.

Historically, essentially the most primary distinction is that between procedural memory (an motion system that's expressed via conduct; e.g., when riding a bicycle) and declarative memory (a cognitive system that is expressed by propositional knowledge; e.g., when taking a classroom take a look at). Each procedural and declarative memory are seen as consisting of a number of subdivisions (Eichenbaum & Cohen, 2001; Schacter & Tulving, 1994; Schacter, Wagner, & Buckner, 2000; Squire, 1992; Squire & Kandel, 1999; Squire & Zola, focus and concentration booster 1998). This text describes a concept of episodic memory, one of the 2 assumed subdivisions of declarative memory. However, because the theory of episodic memory can be only incompletely understood in isolation of the other assumed subdivision of declarative memory, semantic memory--the system that enables us to amass and retain factual information concerning the world (e.g., figuring out that Paris is a pleasant metropolis to visit within the springtime) and from which episodic memory is thought to have evolved, a lot of the discussion will deal with episodic memory in relation to semantic memory.

In this text, the time period ‘episodic memory’ refers to a unique memory system (or capacity) of the brain. Nonetheless, that's not the only which means of episodic memory that one will find in the literature. As an example, the time period is often used to explain the particular experience (content material) that involves thoughts when exercising the capability of episodic memory and the accompanying feeling (phenomenology) that one is at present reliving that earlier experience. In the interest of readability, this text will confer with the contents of episodic memory as ‘remembered experiences’ focus and concentration booster the phenomenological expertise as ‘remembering.’ An analogous concern exists in relation to the idea of semantic memory. Presently, the time period ‘semantic memory’ additionally stands for a capability of the mind. In line with the idea of episodic memory, the assumed evolutionary sequence of episodic memory rising out of semantic memory is mirrored in the worldwide, monohierarchical relation between the 2.

That is, episodic memory shares with semantic memory many options that distinguish both of them (i.e., all of declarative memory) from other major subdivisions of memory, but it also possesses features that it doesn't share with another memory system, together with semantic memory (Mishkin, Suzuki, Gadian, & Vargha-Khadem, 1997; Tulving, 1995). The monohierarchical relation also implies that episodic memory relies on semantic memory in its operations and cannot perform without related elements of semantic memory, whereas semantic memory doesn't rely upon episodic memory in its operations and may perform without episodic memory. This type of a relation between the two memory programs mimics many other related relations within the living world. As a single instance, consider the relation between a visual system that has no sense of colour and a visible system that does: The latter has all the pieces that the former has, plus extra. What makes episodic memory special is that it makes potential psychological time travel into the previous, in addition to into the long run, as might be seen below.

No different memory system has the identical capability, a minimum of not in the sense that episodic memory does. Both techniques allow the organism to find out about facets of its world that are not instantly present. Encoded info (memory traces) may be multimodal (polymodal). Storage of encoded data is transmodal: both remembered experiences and information might be stored unbiased of the modality by means of which they have been acquired. Storage of knowledge is extremely structured. Storage of data is very delicate to context. Stored info is representational (isomorphic) with what is or could possibly be on the planet. Entry to saved info during retrieval is flexible, within limits. Behavioral expression of what's retrieved is elective and never obligatory. Thus, it is possible to carry the retrieved info online, and simply contemplate it. Retrieval of knowledge in each methods requires consciousness. It is not possible to immediately retrieve information from either episodic or semantic memory nonconsciously. After all, numerous processes that underlie the retrieval of remembered experiences and Memory Wave knowledge may take place beyond conscious awareness.
