What is Levels of Processing Theory?
Levels of Processing Theory is a cognitive psychology framework that suggests the depth of processing information affects how well it is encoded, stored, and later retrieved from memory. Introduced by Fergus I. M. Craik and Robert S. Lockhart in 1972, the theory proposes that memory processing occurs on a continuum from shallow (or superficial) processing to deep (or elaborate) processing. Shallow processing involves encoding information based on its sensory characteristics, such as appearance or sound, while deep processing involves encoding based on its meaning or associations with other knowledge. According to the theory, the deeper the processing, the stronger and more durable the memory trace, resulting in better retention and recall.
Examples of Levels of Processing Theory
-
Studying Techniques
When students use rote memorization to learn information, they engage in shallow processing, focusing on the surface features of the material. In contrast, when students engage with the material by elaborating on its meaning, relating it to their own experiences, or connecting it to prior knowledge, they engage in deep processing, which leads to better retention and recall of the information.

Advertising
Advertisers often use deep processing techniques, such as evoking emotions or creating meaningful associations, to make their messages more memorable. By engaging viewers in deeper processing, they aim to create stronger memory traces for their products or brands.
-
Learning a Language
When learning a new language, shallow processing might involve memorizing vocabulary words and their translations, while deep processing might involve using the words in sentences, understanding their contextual meanings, or relating them to similar words in one’s native language. The deep processing approach is more likely to lead to better retention and fluency in the new language.
-
Remembering Names
When meeting new people, shallow processing might involve focusing on the sound of their names, while deep processing might involve associating their names with meaningful information, such as their occupation or a shared interest. The deep processing approach is more likely to lead to better recall of the names.
Shortcomings and Criticisms of Levels of Processing Theory
-
Vagueness
One criticism of the Levels of Processing Theory is that it is vague and lacks a clear definition of what constitutes “deep” or “shallow” processing. This makes it difficult to design experiments to test the theory, as well as to compare and contrast its predictions with those of other memory theories.
-
Descriptive, Not Explanatory
Some critics argue that the Levels of Processing Theory is descriptive rather than explanatory, as it does not provide a clear mechanism or explanation for how different processing depths lead to differences in memory performance. This limits the theory’s ability to provide specific predictions or generate novel insights into the underlying processes of memory encoding and retrieval.
-
Difficulty Measuring Depth
Another criticism is the difficulty in measuring the depth of processing objectively. Researchers often rely on indirect measures, such as the type of task or the amount of time spent on a task, which may not accurately capture the depth of processing that occurs.
-
Overemphasis on Depth
Lastly, the Levels of Processing Theory has been criticized for overemphasizing the role of depth in memory performance, potentially neglecting other factors that can influence encoding, storage, and retrieval. For instance, the theory does not account for the effects of factors such as attention, motivation, or the influence of the individual’s cognitive abilities on memory performance.
