Memory Description



Memoryis defined as the process through which information is encoded,stored and retrieved.The encoding process involves theregistration and combining the received information, thus allowing itto be sensed in the form of physical or chemical stimuli. The storageprocess entails recording the encoded information to enhanceretrieval, while the retrieval process involves recollecting thestored information (Kahana, 2012). Unlike erroneously thought, memoryis a combination numerous integrative. These different functions canbe analyzed by differentiating the types of memory, which are thesensory, short-term as well as long-term memories (Kahana, 2012).

Thesensory memory encodes and stores information from the sensory organsand retains it accurately but for a short time. This makes thesensory memory be regarded as being a component of the perceptionprocess. Conversely, memory which is of short-term in nature recordsthe daily occurrences such as what one hears or sees. However, theinformation stored in the short-term memory disappears quickly unlessefforts to retain it are made (Kahana, 2012). Finally, the long-termmemory stores important events marking human lives, thus allowing onekeep meaning of words as well as the cognitive and physical skillslearned over time. Long-term memory is further divided into thedeclarative memory as well as non-declarative memory. It is worthnoting that, the declarative memory involves memory which can bedescribed using words, while the non-declarative or explicit memorycan only be expressed by action rather than words (Kahana, 2012).

Inretrospection, human memory is an interaction of different functionsthat can be divided into sensory, short-term and long-term memory(Kahana, 2012). Sensory memory stores information from sensoryorgans but for a very short time while the short term memory recordsdaily occurrences. The sensory and short-term memory creates astepping stone to the long-term memory. This is divided intodeclarative memory, a memory that can be described by words, andnon-declarative memory which can only be described through action.
