Levels of processing: A framework for memory research

fergus craik and robert lockhart

The effect of language group was different for each type of task: Monolinguals and bilinguals performed similarly on working memory tasks, monolinguals performed better on lexical retrieval tasks, and bilinguals performed better on executive control tasks, with some evidence for larger language group differences in older participants on the executive control tasks. Current Opinion in Neurobiology, 10, 224-231. The results suggest that older adults have greater difficulties in carrying out controlled retrieval processes to access specific information compared to their younger counterparts. Results replicated the finding that bilingual patients are several years older than comparable monolinguals at both age of symptom onset and date of first clinic visit. Those who used Welsh less in daily life had better performance on one test of English vocabulary.

There was a non-significant difference in age at the time of diagnosis, with bilinguals being on average 3 years older than monolinguals, but bilinguals were also significantly more cognitively impaired at the time of diagnosis. In listening to a conversation, for example, our goal may be to comprehend what is being said, but it may also be to infer the speaker's intelligence, mood, or intentions, or the origin of a distinctive accent. The other idea is to represent redundancy in terms of intercorrelations among the component values of a trace. Experiment 2 showed that surprise immediate recall of 8-item lists did demonstrate a levels-of-processing effect, however. Neural correlates of the episodic encoding of pictures and words. What if Fergus became the depending on your feelings about and as possible fifth Beatles? For example, the recall value of a personality trait adjective is higher when subjects are asked whether the trait adjective applies to them than when asked whether trait adjective has a meaning similar to another trait.

The basic claim of levels of processing as a research framework is that a thorough understanding of remembering requires a careful analysis of the way in which and the degree to which coding processes involve the construction of meaning. It was shown that these errors could not be attributed to failure of discrimination during stimulus presentation. Looking at how older people retrieve memories has enabled Fergus to distinguish between memories that are easily triggered by context and memories we have to dredge up through our own efforts. An alternative framework for human memory research is then outlined in terms of depth or levels of processing. For example, auditory stimuli spoken words and sounds have the highest recall value when spoken, and visual stimuli have the highest recall value when a subject is presented with images.

One study suggests that there is a difference in mental processing level due to innate differences between visual and tactile stimuli representations. Neural imaging studies show decreased activity when words and images are presented to older subjects than with younger subjects, but roughly equal activity when assessing semantic connections. We studied oscillatory mechanisms of successful memory formation in 47 younger and 52 older adults in an intentional associative memory task with cued recall. During his time at the , Craik met his wife, Anne, through a study for his undergraduate thesis. Reports from Toronto and Hyderabad showed a significant effect of speaking two or more languages in delaying onset of Alzheimer's disease by up to 5 years, whereas the Montreal study showed a significant protective effect of speaking at least four languages and a protective effect of speaking at least two languages in immigrants. The role of attention at encoding and retrieval is discussed. The Story Following his academic training and a 6-year teaching stint at Birkbeck College in London, Craik came to the University of Toronto.

This in turn explained why certain things are better remembered than others. Overall, accuracy and confidence jointly influence age-related changes to destination memory, a fundamental component of successful communication. The observation of a bilingual advantage in executive control tasks involving inhibition and management of response conflict suggests that being bilingual might contribute to increased cognitive reserve. The fourth section on attention and memory has two articles that report on the effects of divided attention on subsequent memory, and differences between implicit and explicit memory processes. Performance was compared to a group of healthy age-matched control participants and a group of young participants.

Errors showed a systematic relationship to original stimuli. He has served as Editor of the Journal of Verbal Learning and Verbal Behavior and been a member of the editorial boards of seven other journals. In the case of free recall, the first reason for assuming such a flow and two separate storage mechanisms may be found in a very prominent and reliable characteristic of free recall—the serial position function. For example, bilingual Russian immigrants to the United States can recall more autobiographical details of their early life when the questions and cues are presented in Russian than when they are questioned in English. Summary Levels of processing: The idea that the way information is encoded affects how well it is remembered.

The basic difference between recall and recognition is probably whether or not the S can readily generate all possible alternatives. For example, giving words a meaning or linking them with previous knowledge. This review article surveys the evidence for age-related changes in memory from cognitive and neuroimaging studies. Craik felt that memory must incorporate a series of analyses as well that range from shallow to deep, with the varying depths of encoding representing different levels of memory processing. There are, moreover, a variety of systematic experimental effects that can be worked on this curve. Other examples are rating a word's pleasantness, deciding how many syllables it has, and whether it is spoken by a male or a female voice. Still, there is an increased level of activity in the left prefrontal cortex when older adults undergo some nonverbal tasks of retrieval when compared to younger individuals.

Stuss and Benson's The Frontal Lobes, published in 1986, provided a springboard into the current era by cogently synthesizing anatomical and experimental human and animal research to date. Seguidamente proponen un marco alternativo en términos de niveles de procesamiento, manteniendo que el trazo de la memoria constituye un subproducto del análisis perceptivo y que su persistencia constituye una función positiva de la profundidad con la que se analiza el estímulo. It suggests that the field of cognitive ageing was significantly influence by Donald Broadbent's Perception and Communication and Alan Welford's Ageing and Human Skill. Finally, he repatriated the concept of consciousness from its intellectual exile under behaviorism, stating boldly in 1975 that the construct was respectable, useful, and probably necessary. Journal of Verbal Learning and Verbal Behavior 11, 671-684. A common strategy with verbal material is to rehearse it by silently repeating a word or phrase over and over. The present study investigates a possible neural correlate of this behavioral effect.

Again, the important point is that successful remembering is less a matter of conscious effort than of being led to perform an orienting task that demands deep levels of processing. Some of his more specific research interests include: mood congruence and mood dependence in learning and remembering; memory impairments associated with bipolar affective illness; the cognitive correlates of dissociative identity disorder; and subjective, behavioral, and neural differences between field first-person perspective and observer third-person perspective memories. Following this they propose an alternative framework in terms of processing levels, keeping the concept of memory trace as a perceptive analysis subproduct whose persistence is a positive function of the depth of the stimulus analysis. Each word was presented along with three questions. Participants encoded words in different contexts and were given recognition tests. Comparing the effects of aging and background noise on short-term memory performance.

Later research indicated that processing is more complex and varied than the levels of processing theory suggests. Indeed, we can think of our everyday cognitive activity in terms of a continuous sequence of orienting tasks as our knowledge, goals, and needs interact with the circumstances of the moment. Cognitive reserve is a crucial research area in the context of an aging population; the possibility that bilingualism contributes to cognitive reserve is therefore of growing importance as populations become increasingly diverse. This form of memory is capable of storing information for 30 seconds or even less without rehearsal. This can be thought of as a corollary of the familiarity modifier, because stimuli specifically related to an event in a person's life will have widespread activation in that person's semantic network.
