Semantic relations between encoding and retrieval in cued recall

Two experiments were conducted to test the encoding-specificity hypothesis. In Experiment 1, subjects were presented pairs of coordinates to study, followed by a cued-recall test. Semantically weak and strong coordinates (defined by the degree of featural overlap shared with the pairs) served as encoding and retrieval cues. The semantic strength of the retrieval cue proved to be the most important factor in recall, whereas the re-presentation of an unrelated cue previously seen during encoding led to no facilitation of recall. In Experiment 2, three noun coordinates of varied semantic interrelatedness were presented for study and then were cued for recall by novel semantically strong or weak coordinates. Maximum recall was achieved when a strong encoding condition was matched with a strong retrieval cue. Implications of these findings for an encoding-specificity hypothesis were discussed.     

Hypermnesia in free recall and cued recall

In three experiments, categorized lists and both free recall and cued recall tests were used to examine hypermnesia. In Experiment 1, materials were drawn from obvious and nonobvious categories in an attempt to vary the amount of relational processing at encoding. The study materials in Experiment 2 consisted of a long word list that comprised several exemplars from each of a number of common categories. In Experiment 3, a single exemplar was drawn from each of 45 categories. In each experiment, similar magnitudes of hypermnesia were obtained on free and cued recall tests. Examination of the specific items recalled across tests indicated that similar processes underlie the hypermnesic effect for both test conditions. Implications of the results for extant accounts of the hypermnesic effect are discussed. It is concluded that the dynamics of retrieval processes change in a systematic fashion across repeated tests and the retention interval following study and that an adequate account of the nature of these changes in retrieval dynamics is essential to our understanding of hypermnesia and related phenomena.     

A developmental study of attribute encoding in free recall

In two studies, subjects from second-grade, sixth-grade, and college were presented lists of unrelated words for single-trial free recall. Embedded in the list were critical items that were either semantically or phonemically related or else were completely unrelated. The sets of related items were either massed or distributed in the longer list. For second-graders, recall of Phonemic words was better than recall of Semantic words while the reverse was true for sixth-graders. Recall of Semantic distributed words by second-graders and of Phonemic distributed words by sixth-graders did not differ from recall of unrelated words. College students recalled Phonemic and Semantic words equally well and all related words better than unrelated words. Developmental trends were seen in the salience of particular attributes and in the utilization of low salient attributes.     

Memory for previous recall: a comparison of free and cued recall

Case studies of individuals who claimed to have recovered previously repressed memories of abuse during situations that involved memory cueing revealed that some individuals had discussed abuse with others during an earlier time period. Termed the ‘forgot‐it‐all‐along’ effect, this phenomenon has legal implications for statutes of limitations. Two experiments provide evidence for differences between free recall and more directed (recognition or cued recall) test conditions in the accuracy of memories for previous recall. Participants more often erred by claiming they had not previously remembered recognized (Experiment 1) or cued (Experiment 2) sentences than freely recalled sentences, and this difference was obtained even when the number of remembered sentences was equivalent across conditions (Experiment 2). These studies document that memory for previous recollection is less accurate for cued memories even when remembered events do not produce feelings of shock or surprise.

A ten-year longitudinal examination of repetition priming, incidental recall, free recall, and recognition in young and elderly

The effects of age and time on nondeclarative and declarative memory in young and elderly were examined in a 10-year longitudinal study using tests of word-stem priming, incidental recall, free recall, and recognition. The elderly were significantly impaired on all tests, but no reliable longitudinal decrement by the elderly was detected for priming, incidental recall,or recognition. The elderly demonstrated a significant longitudinal decline in declarative memory as assessed by a test of free recall. While nondeclarative memory declines with age, the longitudinal findings are consistent with the view that declarative memory is more susceptible to the effects of aging.     

Recognition failure of recallable words: free and cued recall compared

The experiment reported was conducted with the purpose of studying whether the phenomenon of recognition failure of recallable words would hold for a paradigm which involves a free recall test rather than a cued recall test used in previous research. The 3×2 design used comprised two between-subjects factors: the subjects were instructed that a recognition test, a cued recall test, or a free recall test would follow the study trial, but the actual test sequence given was recognition followed by cued recall, or recognition followed by free recall. The results demonstrate that cases of recognition failure of recallable words do occur in all six conditions, but the amount of recognition failure for the recognition-free recall test sequence was less than that predicted from the Tulving & Wiseman (1975) function. In line with previous research the data for the recognition-cued recall test sequence showed the amount of recognition failure that was predicted by this function.     

Primacy and recency in primed free association and associative cued recall

Two experiments compared the serial positions of primed words in an implicit free association test with words recalled in a cued recall test. In both tests, weakly or strongly related word pairs were studied, and the first words of each pair formed the test cues. In the implicit test, weakly related words pairs showed primacy and extended recency effects but strongly related word pairs did not. In the explicit test, both weakly and strongly related word pairs showed primacy and extended recency effects. These functional dissociations between implicit and explicit memory tests indicate that strongly related word pairs are encoded together because they have unitized memory representations that function as integrated units without requiring any additional associative links to be made, but that an additional system or process is required to strengthen weakly related word pairs during encoding. In addition, a further additional system or process is accessed by explicit retrieval.     

Developmental trends in recall of central and incidental auditory material

An auditory recall task, involving central and incidental stimuli and designed to correspond to that used in visual selective attention studies, was developed and presented to second-, fourth-, sixth-, and eighth-graders. There were significant differences in favor of older compared to younger Ss and girls compared to boys. In addition, Ss performed better when animals were the relevant and foods the irrelevant stimuli than vice versa. The nature of the developmental increase in auditory recall of central vs incidental stimuli demonstrated in this task was discussed in terms of developmental trends found in the visual modality. The sex differences and differences found for the animals vs foods condition were discussed with regard to differential short-term memory strategies.     

Determinants of cued recall

This paper reports two cued recall experiments in which the degree of preexperimental associative strength between rhyming cues and their respective targets is manipulated whilst holding the extent of informational overlap between them constant. Both experiments show that strong rhyming cues are more efficient than weak rhyming cues in eliciting target retrieval in both a short-term and a long-term memory situation. The results are interpreted as consistent with the generationrecognition theory of retrieval and inconsistent with predictions made by the encoding specificity principle. It is therefore suggested that caution must be applied when extending the encoding specificity principle to experimental situations other than that from which it is derived. Implications for the distinction between scanning and reconstructive modes of retrieval are also briefly considered.     

Levels of processing with free and cued recall and unilateral temporal lobe epilepsy

This study investigates the role of the temporal lobes in levels-of-processing tasks (phonetic and semantic encoding) according to the nature of recall tasks (free and cued recall). These tasks were administered to 48 patients with unilateral temporal epilepsy (right "RTLE"=24; left "LTLE"=24) and a normal group (n=24). The results indicated that LTLE patients were impaired for semantic processing (free and cued recall) and for phonetic processing (free and cued recall), while for RTLE patients deficits appeared in free recall with semantic processing. It is suggested that the left temporal lobe is involved in all aspects of verbal memory, and that the right temporal lobe is specialized in semantic processing. Moreover, our data seem to indicate that RTLE patients present a retrieval processing impairment (semantic condition), whereas the LTLE group is characterized by encoding difficulties in the phonetic and semantic condition.     

On the relationship between categorical frequency estimation and cued recall

In a categorical frequency-estimation task, subjects have to indicate the number of exemplars from particular categories that have been shown on a list. In three experiments, the relationship between this task and the recall of exemplars with category names as cues was investigated. Three variables (generation, blocking of category exemplars, and provision of extralist cues) were shown to have identical effects on the two tasks. These results support a model of categorical frequency estimation in which subjects use a category name to retrieve exemplars and then base their frequency estimate on a count of the exemplars that have been retrieved.     

Effects of semantic and nonsemantic cued orienting tasks on associative clustering in free recall

Semantic and acoustic processing in free and cued recall by educable mentally retarded adolescents

The abilities of educable mentally retarded adolescents to encode and retrieve words with semantic and acoustic cues were investigated in a free and cued recall task. On each of three trial blocks, seven groups of subjects were presented 20 unrelated stimulus words. Groups received either semantic, acoustic, or no encoding cues along with the stimuli. Free recall was requested from all subjects, followed immediately by a second period of either free recall or cued recall with the semantic or acoustic cues. Semantic cues were most effective when presented both at encoding and retrieval. The subjects were unable to use acoustic information as effective retrieval aids. Results were discussed in terms of encoding dimension dominance and mediational deficiencies.     

How to avoid developmental effects in free recall

Immediate and final free recall was tested in children from grades 4, 6, and 8, using lists of words and lists of tasks which the children performed. The expected developmental effect was found in both the immediate and the final free recall of the words, but there were no significant differences in the recall of the tasks as a function of age. These data are discussed within the Flavell-Brown framework of strategic and nonstrategic memory tasks.     

Effects of incentive on cued recall

Words associated with high monetary incentive were better recalled than those associated with low incentive. This effect was found to depend on differential rehearsal, since it was eliminated or markedly attenuated when manipulations designed to minimize rehearsal were used. High-incentive words are more elaborately or extensively processed than low-incentive words, but they are not processed in a qualitatively different manner. This greater elaboration of processing appears to be limited to those attributes or features believed to be relevant to the subsequent retention test. The implications of these findings for incentive theories are discussed.     

Retrieval operations in cued recall and recognition

The present study compared the effects of two classes of experimental manipulations on the recognition and cued recall of target words learned in the presence of list cues. One class of manipulations, learning instructions (repetition vs. meaningful rehearsal), had similar effects on recall and recognition, whereas the other, preexperimental association between target and cue words, had separable effects: Cue-to-target association affected only recall, while target-to-cue association affected only recognition performance. Recall and recognition were thus viewed as fundamentally similar processes, both of which require retrieval operations. Differences between the two were attributed to the differential abilities of the recall and recognition retrieval cues to access the original episodic event.     

Retrieval processes in recognition and cued recall

The present studies used response time (RT) and accuracy to explore the processes and relation of recognition and cued recall. The studies used free-response and signal-to-respond techniques and varied list length and presentation rate. In Experiment 1, the free-RT distributions for recognition had much lower mean and variance than those for cued recall. Similarly, signal-to-respond curves showed fast rates of accumulation of information in recognition and slow rates in recall. (Quantitative models of the results are presented in the companion article by D. E. Diller, P. A. Nobel, and R. M. Shiffrin, 2001). To rule out the possibility that the slower responses in cued recall were due to a fast retrieval process followed by a slow process of cleaning up the retrieved trace for output, additional signal-to-respond tasks provided the relevant alternatives at test. Yet, these conditions showed slow growth rates, similar to those seen in recall. The results support the hypothesis that retrieval processes differ for single-item recognition and cued recall, with retrieval in cued recall (and associative recognition) due to a sequential search.     

Event frequency and children's suggestibility: a study of cued recall responses

Research examining the effect of repeated experience on children's suggestibility for particular kinds of information has produced differing results. In one study, responses to recognition questions revealed heightened suggestibility for variable details in children who repeatedly experienced an event compared to children who experienced an event once. In other studies, no such effect was found with cued recall. In this study, 4–5‐year old children engaged in one or four play sessions. Children were later given a biasing interview wherein half of the details were incorrectly represented. Children were then given a final memory test using free and cued recall prompts that was preceded by one of three instruction types: no special instructions, moderate instructions, or opposition instructions. Children in the repeated‐event condition were more suggestible than those in the single‐event condition, regardless of instructions. No significant differences in suggestibility were found across instructions conditions. Copyright © 2004 John Wiley & Sons, Ltd.     

Components of recollective experience in cued recall

Components of recollective experience were examined in relation to cue effectiveness by presenting subjects with their own or someone else's associations as retrieval cues. When recalling an item, subjects indicated whether they consciously recollected its prior occurrence ("remembering") or recalled it on some other basis, in the absence of conscious recollection ("knowing"). The results showed that cue compatibility (self-generated vs. someone else's cues) and retention interval (immediate vs. delayed test) selectively impaired retention accompanied by recollective experience, as measured by remember responses, but had reduced effects in the absence of recollective experience, as measured by know responses. The results are discussed in terms of variables dissociating judgments of recollective experience.
