Priming in psychology refers to activating parts of particular representations or associations in memory just before carrying out an action or task. Psychology (from Greek grc ψῡχή psȳkhē, "breath life soul" and grc -λογία -logia) is an Academic and In Psychology and Marketing, two concepts or stimuli are associated when the experience of one leads to the effects of another due to repeated pairing In Psychology, memory is an organism's ability to store retain and subsequently retrieve information It is considered to be one of the manifestations of implicit memory. Implicit memory is a type of memory in which previous experiences aid in the performance of a task without conscious awareness of these previous experiences A property of priming is that the remembered item is remembered best in the form in which it was originally encountered. If a priming list is given in an auditory mode, then an auditory cue produces better performance than a visual cue. The visual system is the part of the Nervous system which allows organisms to see.
Priming is also an experimental technique by which a stimulus is used to sensitize the subject to a later presentation of the same or similar stimulus. For example, when a subject reads a list of words including the word table, and is later asked to complete a word that starts with tab, the list "primes" the subject to answer table, meaning that the probability that the "primed" subject answers table is higher than for non-"primed" subjects.
Priming can also be demonstrated in the following way. Subjects are shown an incomplete sketch and asked what it is. If they fail to identify the sketch, they are shown another sketch that is slightly more complete. This process continues until they eventually recognize the picture. When subjects are shown the same sketch at a later date, they will identify the sketch at an earlier stage than was possible for them the first time. 
Priming can be conceptual or perceptual. Conceptual priming is based on stimulus meaning and is enhanced by semantic tasks. For example, when primed with the word table, the subject will show priming effects on the word chair, because table and chair belong to the same category. Perceptual priming is based on the stimulus form and is enhanced by the match between stimulus form at study and test. Perceptual priming is sensitive to the modality and exact format of the stimulus. An example of perceptual priming is seeing the same sketch in the experiment mentioned above.
An important feature of a priming task is that amnesic subjects perform as well on it as control subjects do, indicating through their performance that they, too, remember what was on the previous study list, even though they report no conscious recollection of ever having seen the list. Amnesia (from Greek) is a condition in which Memory is disturbed This is taken as one kind of evidence that implicit and explicit memory are different. Implicit memory is a type of memory in which previous experiences aid in the performance of a task without conscious awareness of these previous experiences Explicit memory is the conscious intentional recollection of previous experiences and information 
Priming of amnesic subjects with words that were unknown to them prior to the injury is impaired, which has been argued to demonstrate that priming depends on the activation of existing memory, however this interpretation is undermined by normal or near normal priming using nonverbal materials in amnesic subjects.
