Text recall in adulthood: The role of intellectual abilities.

This study examined age-related predictive relationships between an array of psychometric intellectual ability markers and text recall performance in adulthood. One hundred and fifty women from three age groups (21–39 years, 40–58 years, 60–78 years) read and recalled four narrative stories at three delay intervals and completed a battery of 12 factor-analytically defined intellectual ability tests. The results indicated (a) that text memory performance in adulthood is predicted by multiple abilities; (b) that age differences in text memory performance overlap highly with age differences in multiple abilities, although the latter do not fully account for the former; (c) that modest Age?×?Ability interactions exist but are not consistent with previous reports, suggesting that age differences decrease with increasing ability levels; and (d) that the pattern of intelligence-text recall relationships differs by age group.

The Effects of Readers' Misconceptions on Comprehension of Scientific Text.

The aim of the present study was to investigate the effects of readers' misconceptions on text comprehension. College students with misconceptions in science were asked to read and recall a text that contradicted their misconceptions. Students with no misconceptions served as the control group. Both online (think-aloud, reading times) and offline (recall) measures were obtained. The results suggest that readers' misconceptions often do not affect the online processes themselves but do influence the content of those processes and, consequently, the offline memory representation for the text after reading is completed.

Text structure and children's comprehension and memory for expository material.

Investigated the effects of instruction focusing on text structure on 90 5th graders' comprehension and memory for expository material. In 2 experiments, instruction in a hierarchical summarization study strategy focusing on the organization of ideas in text was compared with the more conventional classroom procedure of answering questions after reading. In Exp I, the experimental instruction group had short-answer test scores as high as the conventional instruction group and recall and organization scores that were higher. Similar results were not found in Exp II, an attempt to replicate Exp I. Further analyses revealed that the differences between the studies may have been due to differences in Ss' ability to master the study strategy. It is concluded that even though instruction in a study strategy focusing on text structure can enhance elementary school students' memory for expository material, as is typically found in their content area textbooks, it seems that students must be able to perform the study strategy reasonably well before it will markedly improve their recall.

Relationships between metamemory, memory predictions, and memory task performance in adults.

A cross-sectional sample of adults recalled categorized word lists and narrative texts. Subjects gave performance predictions before each of 3 recall trials for each task. Older subjects had poorer memory performance and also predicted lower performance levels than did younger subjects. The LISREL models suggested (a) direct effects of memory self-efficacy (MSE) on initial predictions; (b) upgrading of prediction–performance correlations across trials, determined by direct effects of performance on subsequent predictions; (c) significant effects of a higher order verbal memory factor on MSE; and (d) an independent relationship of text recall ability to initial text recall performance predictions. These results lend support to the theoretical treatment of predictions as task-specific MSE judgments. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Semantic Organization and Verbal Memory Efficiency in Patients With Schizophrenia.

The role of semantic organization in verbal memory efficiency in schizophrenia was investigated. Patients and healthy controls were administered a free-recall task involving 1 nonsemantically organizable list, 1 list organizable in semantic categories with typical instances, and 1 list organizable in semantic categories with atypical instances. Reduced semantic organization was observed in patients. Regression analyses showed that the semantic clustering score in the atypical organizable list made a significant contribution to recall performance in patients. When semantic clustering was controlled, the effect of diagnosis on free recall was significant. These results suggest that depth of semantic organization is a crucial factor of verbal memory performance in schizophrenia. However, semantic organizational deficit does not account for the whole recall impairment. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The deterioration of semantic memory in Alzheimer's disease.

Semantic memory impairment is a common feature of dementia of the Alzheimer type (DAT). Recent research has shown that patients with DAT are more impaired (relative to non-demented controls) in generating exemplars from a particular semantic category (e.g., animals) than words beginning with a particular letter, exhibit an altered temporal dynamic during the production of category exemplars, are impaired on confrontation naming tasks and make predominantly superordinate or semantically related errors, consistently misidentify the same objects across a variety of semantic tasks, and have alterations in multidimensional scaling models of their semantic network that are indicative of a loss of concepts and associations. These results are consistent with the view that Alzheimer's disease results in a breakdown in the organization and structure of semantic knowledge as neurodegeneration spreads to the association cortices that presumably store semantic representations.

Mood and memory.

Describes experiments in which happy or sad moods were induced in Ss by hypnotic suggestion to investigate the influence of emotions on memory and thinking. Results show that (a) Ss exhibited mood-state-dependent memory in recall of word lists, personal experiences recorded in a daily diary, and childhood experiences; (b) Ss recalled a greater percentage of those experiences that were affectively congruent with the mood they were in during recall; (c) emotion powerfully influenced such cognitive processes as free associations, imaginative fantasies, social perceptions, and snap judgments about others' personalities; (d) when the feeling-tone of a narrative agreed with the reader's emotion, the salience and memorability of events in that narrative were increased. An associative network theory is proposed to account for these results. In this theory, an emotion serves as a memory unit that can enter into associations with coincident events. Activation of this emotion unit aids retrieval of events associated with it; it also primes emotional themata for use in free association, fantasies, and perceptual categorization.

The dynamics of memory retrieval in older adulthood.

One of the most robust findings in cognitive aging is that of a significant decline in self-initiated recall from episodic memory. In laboratory studies this deficit can be seen in significant age differences in word-list free recall. In this article, the authors focus on free recall of categorized word lists where one observes "response bursting" in the form of a rapid output of within-category items with longer delays between categories. Age differences appear primarily in between category latencies, results that are consistent with a relative sparing of semantic memory combined with an age-deficit in episodic retrieval. When adjusted for differences in overall mnemonic ability, it is demonstrated that the relationship between organization and learning remains invariant with normal aging. The authors argue that the locus of the age deficit in free recall lies at the level of temporal coding of items and the use of temporal associations to guide recall.

Developmental differences in organization and recall: Training in the use of organizational techniques.

Used an alternating sort-recall procedure in 3 experiments to train 204 elementary school children in the use of organizational techniques as memory aids. All Ss sorted a group of words into 2–7 categories, and some Ss were required to learn the sorting patterns generated by adults. In Exp I, the semantic sophistication of a S's sorting style predicted recall performance. Further, the tendency to improve memory performance as a result of being constrained to adult sorting patterns varied with age; constrained 5th graders significantly improved their recall, whereas the recall of 3rd and 7th grade Ss was not affected by this training. However, more detailed organizational training in Exp II facilitated the recall of 3rd graders. In Exp II, it was found that the constraining procedure was not necessary for facilitation to be observed. Rather, instructions to group words on the basis of meaning were sufficient to produce improved recall. Further, improvements in sorting style accompanied all significant changes in recall. Findings are discussed in terms of a discrepancy between the information which a child has in permanent memory and that which he uses spontaneously in the context of a memorization task. The importance of input organization as a mediating factor in memory performance and development is suggested. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The robustness and temporal course of the story schema's influence on recall.

Three experiments are reported in which subjects were asked to remember simple stories they had read. The goal was to examine the power of the story schema, postulated in a contemporary story grammar, to influence subjects' level and organization of memory, particularly when they are presented with scrambled versions of stories. The results of Experiment 1 are consistent with previous findings, and we demonstrated the schema's influence on the level and organization of free recall. In Experiment 2 we demonstrated the strong influence of the schema on recall of details (measured by a cloze procedure), as well as recall for the story's gist (measured by a summary construction task). Finally, in Experiment 3 we demonstrated that the schema's influence on the organization of memory holds over time and serves to buttress the more abstract and general elements of the narrative.

Verb imagery and noun phrase concreteness in the recognition and recall of sentences.

Examined the role of verb imagery and noun phrase concreteness in determining sentence imagery and memory in 2 experiments with a total of 111 male and 17 female university students. Semantic changes in sentences were recognized more often if the noun phrases were concrete rather than abstract. Free recall of sentences was affected similarly by phrase concreteness. Verb imagery, however, had no effect on either recognition or recall performance. Analysis of recall by type of word indicated that organization of recall centered upon the nouns. Implications of these results for the hypothesis of imaginal coding of concrete sentence meaning are discussed.

Elaboration, organization, and the self-reference effect in memory.

Conducted 5 experiments with 272 undergraduates that challenged the interpretation of the self-reference effect that proposes that self-reference produces a more elaborate memory trace than semantic encoding by demonstrating that self-referent and semantic encodings produce virtually identical free recall levels if they are first equated for the amount of organization they encourage. Exp I attempted to replicate the findings of T. B. Rogers et al (see record 1979-25246-001) by comparing self-referent, semantic, and structural encoding tasks and examining cluster differences between these encoding tasks during free recall. The experiments that followed orthogonally varied organization and the encoding task. Overall results lead to the following conclusions: Organization, not elaboration, is responsible for the superior recall performance obtained when information is encoded self-referentially. Organization is not a necessary component of self-referent encoding and can be orthogonally varied within self-referent and semantic encoding tasks. How a single-factor theory based on organization can account for many of the self-referent recall findings reported in the literature is discussed.

Tracking conceptual and semantic processing in the comprehension and production of text and discourse.

Current research on text and discourse processing has focussed on the nature of conceptual and semantic representation and processing, and the relationship between conceptual knowledge and the structure and processing of text or discourse. It is now generally recognized that discourse comprehension involves the construction of a conceptual "situation model" by a listener or reader, that is, a conceptual representation that is appropriate to the content and context of a text or discourse. Current psychological models of discourse production view discourse processing as a process of translating conceptual knowledge structures into "rhetorical" discourse structures that are appropriate to a communicative situation and setting. One important component of such translation is the construction of a conceptual situation model to be communicated to a listener or reader. A second is the construction of a propositional text base to specify precisely the semantic content to be expressed through segments of text or discourse. A third is to define a discourse organization that appropriately guides the reader in constructing a conceptual situation model from the text.

Effects of text genre and verbal ability on adult age differences in sensitivity to test structure.

The present study examined the effects of verbal ability and text genre on adult age differences in sensitivity to the semantic structure of prose. Young and older adults of low or high verbal ability heard narrative and expository passages at different presentation rates. The results demonstrated that older adults recalled less than younger adults and that age differences in recall were larger for low-verbal adults and expository texts. However, subjects from all groups favored the main ideas in their recalls for both types of passages. The results indicate that adult age similarities in the ability to focus on the main ideas when processing prose was not compromised by the verbal ability of the subjects or the organization of the passages used. However, the results also demonstrate how the characteristics of the learner and the characteristics of the text modulate the size of the age differences observed.

Keyword and context instruction of new vocabulary meanings: Effects on text comprehension and memory.

New vocabulary was taught by one of three methods: keyword, semantic context, and no-strategy control. The semantic context method involved presenting subjects verbal contexts from which they might infer the meanings of the words, followed by explicit provision of the definitions. After a vocabulary definition acquisition phase, subjects in all conditions read a text in which some of the newly acquired vocabulary was embedded, with half of the texts providing richer contextual clues to the meaning of the target items (embellished text) than the other texts (unembellished text). Reading times did not differ as a function of acquisition condition, nor did one acquisition condition consistently elicit better performance than the others across text comprehension/memory measures. The one significant difference in comprehension favored the keyword method. The usual superiority of the keyword method for recall of definitions given vocabulary items was also replicated. Despite theoretically motivated concerns that keyword-method acquisition of definitions might inhibit comprehension of vocabulary in discourse relative to a semantic context method, none of the reaction time (RT) or performance analyses reported here supported those hypotheses. A subsidiary finding was that test text embellishments increased comprehension (as indexed by recall measures), a result suggesting that certain kinds of contextual support can enhance comprehension of "new" vocabulary.

Functional mapping of human memory using PET: Comparisons of conceptual and perceptual tasks.

Tested whether different neurological regions subserved the conceptual and perceptual memory components by using positron emission tomography (PET). Regional cerebral blood flow (RCBF) of 14 Ss (mean age 25 yrs) during 2 conceptual tasks of semantic cued recall and semantic association was compared to a control condition in which Ss made semantic associations to nonstudied words. RCBF during 2 perceptual tasks of word fragment cued recall and word fragment completion was also compared to a word fragment nonstudied control condition. There were clear dissociations in RCBF that reflected differences in brain regions subserving the 2 types of memory processes. Conceptual processing produced more activation in the left frontal and temporal cortex and the lateral aspect of the bilateral inferior parietal lobule. Perceptual memory processing activated the right frontal and temporal cortex and the bilateral posterior areas. (French abstract) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Individual differences in schema utilization during discourse processing.

Discourse processing involves an interaction of text-based and knowledge-based processes. It was hypothesized that college students (N?=?112) would differ in their relative employment of knowledge-based processes, and that Ss would tend to be more "text bound" when they were more "stimulus bound" in another task with analogous processing demands (i.e., an embedded figures test; EFT). Extent of knowledge-based processing (or schema utilization) was assessed by comparing recall of food items from a narrative about a trip to a fancy restaurant with that from a parallel narrative about a trip to a supermarket. Previous research has demonstrated that since the "foods purchased" component of the restaurant schema is more highly constrained than the equivalent component of the supermarket schema, the former supports greater food item recall. As predicted, food item recall was significantly positively correlated with EFT residuals (after predicting EFT from vocabulary test scores) for the restaurant condition, with no correlation for the supermarket control. Other dependent measures yielded the same pattern of positive correlation with EFT or no correlation with EFT as a function of whether performance would be enhanced by schema utilization or not, respectively.

Effects of an organizer on memory for prose.

112 undergraduates read a literature text preceded by either a comparative advance organizer or a placebo introduction. Three hypotheses regarding the interactive effects of the organizer treatment and reasoning skills were tested: the assimilation, the schema plus correction, and the assimilation plus correction hypotheses. Findings favor the assimilation plus correction view, which holds that schema-implied text units are assimilated and obscured in the final text encoding, whereas ideas representing unexpected, schema-modifying information are enhanced. The dominant treatment effect was assimilatory loss of detail associated with implied information. Positive effects on schema-modifying information were observed for Ss with good reasoning skills, as assessed by the Diagramming Relationships and Inference Tests from the Kit of Factor-Referenced Cognitive Tests. Possible explanantions for the results are discussed in terms of reconstructive views of recall, adaptive learning and changes in semantic memory representation, and perceived structural importance of target ideas.
