An experiment on the effect of deeper levels of processing on word retention

Craik and Lockhart argued that memory is a function of the "level" to which material is processed and that this is independent of the amount of repetition or rehearsal of the stimulus.

The distractors were brand names in the same product class as the originally presented ads, but they had not been seen in the experiment. Semantic processing of odors e. The recognition scores were corrected for guessing by subtracting the number of false alarms brand names in correctly checked "yes" from the number of hits brand names correctly checked "yes".

Several studies show that, in older individuals, the ability to process semantically in contrast with non-semantically is improved by this disparity. So, it could be that the results are partly due to more time being spent on the material.

This is the only type of rehearsal to take place within the multi-store model. In particular, levels-of-processing effects appear to be strengthened in patients with age-related memory degradationselectively strengthened in panic disorder patients, unaffected in Alzheimer's disease patients, and reversed in autistic patients.

Memory is just a by-product of the depth of processing of information, and there is no clear distinction between short term and long term memory. Significant time and effort has been invested into researching memory and the effect the depth of processing has on the ability to recall words.

One study found that word completion tasks were unaffected by levels of semantic encodings achieved using three words with various levels of meaning in common.

Neural imaging studies show decreased left-prefrontal cortex activity when words and images are presented to older subjects than with younger subjects, but roughly equal activity when assessing semantic connections. After this phase a result page opened, with a table indicating scores for each phase.

Let us say they tell you they are spending their study time reading and memorizing the words in the margins. A dependent variable is what you measure in the experiment and what is affected during the experiment.

However, as part of this series of studies, Craik and Tulving conducted another experiment where the shallow questions presented to subjects were more difficult to perform and more time consuming to perform than the "deeper" meaning task.

For example, Craik and Tulving have argued that the effects are more accurately characterized as "spread" of processing rather than depth.

Depth of Processing Experiment: How Do You Interact With Information?

The deeper processing again improved recall even though it took less time than the shallow processing procedure. Results Participants recalled more words that were semantically processed compared to phonemically and visually processed words.

Another problem is that participants typically spend a longer time processing the deeper or more difficult tasks. To insure that any observed difference in memory for the ads was not specific to the ads chosen for each condition, a control procedure was used. Archived from the original on Types of Information Interaction Depth of processing describes how you interact with the information.

A framework for memory research. Further, this result continues to be seen even as we age Mandzia, For example, the subject had to determine the pattern of consonants and vowels in the word. Specifically, there is a significantly higher recall value for semantically encoded stimuli over physically encoded stimuli.

Semantic processing of odors e. Further, this result continues to be seen even as we age Mandzia, Nine hundred and ninety nine participants were presented with 26 pairs of words under both semantic and phonemic conditions and then tested to see how many they could recall.

The reason people estimate their ability to recall inaccurately could be one of a many. The levels of processing model changed the direction of memory research.

Therefore, clearly, time on task has nothing to do with the effects of depth of processing. The familiarity modifier has been tested in implicit memory experiments, where subjects report false memories when presented with related stimuli. Want to read the rest of this paper. The tertiary hypothesis is that people will overestimate their abilities and so the predictions for both conditions will be higher than the given value.

You were asked if the words in the second column phonemic processing rhymed with another word. Press the Continue key when you are done. It showed that encoding was not a simple, straightforward process.

Thinking about the meaning of a word is a much deeper level of processing than thinking about what it sounds like or looks like. Hypotheses and general method The “durability of the memory trace is a function of depth of processing.” “Stimuli that are attended to, fully analyzed, and enriched by associations or images yield a deeper encoding of the event, and a long-lasting trace.” “Memory performance would vary systematically with the depth of processing.”.

The levels-of-processing effect, identified by Fergus I. M. Craik and Robert S. Lockhart indescribes memory recall of 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.

levels of processing on memory involves the measurement of subjects' reten- tion of lists of words, Gipe (11) examined the long-term effects of levels of processing on the retention of the meanings of unfamiliar vocabulary words.

The levels of processing model (Craik and Lockhart, ) focuses on the depth of processing involved in memory, and predicts the deeper information is processed, the longer a memory trace will last.

Craik defined depth as: "the meaningfulness extracted from the stimulus rather than in terms of the number of analyses performed upon it.” Author: Saul Mcleod. significant effects. Retention was clearly superior following the deeper processing and, while recall increases with additional processing regardless of depth, the amount of this increase is related to depth.

That is, the benefit to retention provided by additional processing was greater at deep levels than at shallow levels. In the present experiment, levels of processing were measured through three conditions: physical (does the word have four letters), rhyming (do two words rhyme) and semantics (does a word fit into a .
