Priming is a phenomenon of long-term memory that typically increases or decreases an individual's ability to process repeated stimuli, usually consisting of words, ideas, or pictures.  Most long-term memory tasks such as this are comprised of three phases:  1) a study phase, 2) a retention interval in which a diversion task is performed, and 3) a test phase in which memories of the previously studied material are retrieved.  Certain priming tasks are considered to be primarily perceptual in nature, drawing upon processes concerned with the visual, auditory, and tactile forms of a target stimulus.  These include word and picture identification, lexical decision, picture and word naming, degraded picture and word naming, completing word-stems, anagram solution, and word-fragment completion.

Definition of Priming

Priming is a phenomenon of long-term memory that typically increases or decreases an individual's ability to process repeated stimuli, usually consisting of words, ideas, or pictures. Most long-term memory tasks such as this are comprised of three phases: 1) a study phase, 2) a retention interval in which a diversion task is performed, and 3) a test phase in which memories of the previously studied material are retrieved. Priming is often described as a manifestation of implicit memory. One of its properties is that the remembered stimulus is often better remembered later in the form in which it was originally experienced. For example, if a stimulus was given in an auditory form, a later auditory cue would produce more successful performance than a visual cue. Priming can also be used in experimental form whereby a stimulus is presented to a subject to sensitize to a later presentation of the same stimulus or a similar one. Presentation of a particular word such as 'chair' in a list of priming words will later raise the probability of the subject answering with that word when asked to think of a word beginning with the fragment 'cha'.


Perceptual

Certain priming tasks are considered to be primarily perceptual in nature, drawing upon processes concerned with the visual, auditory, and tactile forms of a target stimulus. These include word and picture identification, lexical decision, picture and word naming, degraded picture and word naming, completing word-stems, anagram solution, and word-fragment completion. Perceptual priming is sensitive to the exact format and modality of a certain stimulus.
