Levels of processing model

The levels of processing model, created by Fergus I. M. Craik and Robert S. Lockhart in 1972, describes memory recall of stimuli as a function of the depth of mental processing, where deeper levels of processing produce more elaborate and stronger memory than more shallow levels of processing. Shallow processing (e.g., processing based on phonemic and orthographic components) leads to a fragile memory trace that is susceptible to rapid decay.
