The '''levels-of-processing effect''', identified by [[Fergus I. M. Craik]] and Robert S. Lockhart in 1972, describes [[memory]] [[recollection|recall]] of [[Stimulus (physiology)|stimuli]] as a function of the depth of mental processing. Deeper levels of analysis produce more elaborate, longer-lasting, and stronger memory traces than shallow levels of analysis. Depth of processing falls on a shallow to deep continuum. Shallow processing (e.g., processing based on [[phonemic]] and [[Orthography|orthographic]] components) leads to a fragile memory trace that is susceptible to rapid decay. Conversely, deep processing (e.g., [[semantic processing]]) results in a more durable memory trace.
This theory contradicts the multi-store [[Atkinson-Shiffrin memory model]] which represents memory strength as being continuously variable,
In a study from 1975 (Craik and Tulving) participants were given a list of 60 words. Each word was presented along with three questions. The participant had to answer one of them. Those three questions were in one of three categories. One category of questions was about how the word was presented visually ("Is the word shown in ''italics''?"). The second category of questions was about the phonemic qualities of the word ("Does the word begin with the sound 'bee'?"). The third category of questions was presented so that the reader was forced to think about the word within a certain context. ("Can you meet one in the street [a friend]"?) The result of this study showed that the words which contained deep processing (the latter) were remembered better.<ref>Craik and Tulving 1975</ref>
