Spacing judgments as an index of integration from context-induced relational processing: Implications for the free recall of ambiguous prose passages

The effect of information integration on the recall of ambiguous prose passages was investigated. In Experiment 1, subjects read ambiguous passages that were difficult to comprehend without titles. In judging the relative positions in the passages of pairs of test sentences, subjects performed better when they read passages headed by a suitable title than when they read untitled passages or received a title at the time of testing. In Experiment 2, subjects provided with a title at encoding also better discriminated complete old sentences from foils composed of fragments of two different old sentences than did subjects provided with no titles or with titles at the time of testing. These two tests index the degree of inter- and intrasentence information integration, respectively. Two findings indicated that integration affected free recall of an ambiguous passage. First, when the degree of integration of the passage's propositions was controlled, free recall of the passage was no different for subjects who did or did not know the passage's title at encoding. Second, inducing subjects to comprehend the passage's sentences individually, without relating them to one another, reduced free recall of the passage.

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.

Part‐set cuing of texts,scenes, and matrices

In four experiments, we extended the study of part‐set cuing to expository texts and pictorial scenes. In Experiment 1, recall of expository text was tested with and without part‐set cues in the same order as the original text; cues strongly impaired recall. Experiment 2 repeated Experiment 1 but used cues in random order and found significant but reduced impairment with cuing. Experiments 3 and 4 examined the part‐set cuing of objects presented in a scene or matrix and found virtually no effect of cuing. More objects were recalled from the scene than from the matrix, indicating that the scene's organization aided memory, but the cues did not assist recall. These results extend the domains in which part‐set cues have either impaired or failed to improve recall. Implications for education and eyewitness accounts are briefly considered.     

Two modality effects in verbal short-term memory: Evidence from sentence recall

This paper investigates the mechanisms underlying the standard modality effect (i.e., better recall performance for auditorily presented than for visually presented materials), and the modality congruency effect (i.e., better memory performance if the mode of recall and presentation are congruent rather than incongruent). We tested the assumption that the standard modality effect is restricted to the most recent word(s) of the sentences but occurs in both verbatim and gist recall (Experiments 1 and 2), whereas the modality congruency effect should be evident for the rest of the sentence when using verbatim recall (Experiment 3) but not when using gist recall (Experiment 4). All experiments used the Potter-Lombardi intrusion paradigm. When the target word was the most recent word of the sentence, a standard modality effect was found with both verbatim recall and gist recall. When the target word was included in the middle of the sentences, a modality congruency effect was found with verbatim recall but not with gist recall.     

Triggering memory recovery: Effects of direct and incidental cuing

The present study examined forgetting and recovery of narrative passages varying in emotional intensity, using what we refer to as the “dropout” method. Previous studies of this dropout procedure have used word lists as to-be-remembered material, but the present experiments used brief story vignettes with one-word titles (e.g., “Torture”, “Insects”). These vignettes showed a strong dropout forgetting effect in free recall. Both text and picture cues from the vignettes eliminated the forgetting effect on a subsequent cued recall test. Vignette-related pictures in an incidental picture naming task, however, triggered little recovery of initially forgotten vignettes, as shown on a post-test. The results extend findings of large forgetting and memory recovery effects to materials that are more naturalistic than word lists. The findings also show that picture cues, which trigger strong memory recovery effects on a direct test of memory, had little effect on recovery when cues were encountered incidentally.     

Effects of titles on the processing of text and lexically ambiguous words: Evidence from eye movements

Providing titles for passages improves the comprehension and memorability of text. Titles have generally been thought to facilitate comprehension at later stages of processing. Consistent with prior research, we found that passages presented with titles were better recalled than those without titles. Furthermore, in Experiment 1, the presence of titles led to fewer regressive eye movements, shorter end-of-sentence reading times, and shorter fixation times on target nouns. Experiments 2 and 3, using ambiguous target words, indicated that except when a very infrequent sense of a word is required, titles provide a strong enough context to allow for ambiguous words to be processed as quickly as control words. The results of the three experiments suggest that titles affect processing at both integrative and lexical stages of reading.     

Explorations in the social contagion of memory

Four experiments examined social influence on the development of false memories. We employed the social contagion paradigm: A subject and a confederate see scenes and then later take turns recalling items from the scenes, with the confederate erroneously reporting some items that were not present in the scenes; on a final test, the subject reports these suggested items when instructed to recall only items from the scenes. The first two experiments showed that the social contagion effect persisted when subjects were explicitly warned about the possibility that confederates' responses might induce false memories and when they were tested via source-monitoring tests that explicitly gave the choice of attributing suggested items to the other person. Levels of false recall and recognition increased with the number of times the misleading information was suggested (Experiment 3), and subjects were more likely to incorporate the erroneous responses of an actual confederate on a recognition/source test as compared with those of a simulated confederate (Experiment 4). Collectively, the data support the claim that false memories may be transmitted between people and reveal critical factors that modulate the social contagion of memories.     

The interim test effect: Testing prior material can facilitate the learning of new material

A wealth of prior research has shown that testing can improve subsequent learning of the initially tested material. In contrast, only one recent study has shown that an interim test over prior material can improve learning of subsequent new material (i.e., an interim-test effect). Five experiments replicated and extended this initial work by exploring the extent to which interim test effects generalize to complex text material. Participants were prompted to recall each section of an expository text before moving on to study the next section, or were only prompted to recall after the final section. In all experiments, recall of the final, target section was greater when prior sections had received interim tests versus no interim tests. Experiment 3 established that the effect was due to interim testing in particular rather than to intervening activity in general. Experiment 4 established that the effect was not due to test expectancy differences. In contrast to prior research, Experiment 4 also provided evidence that the effect is not due to release from proactive interference. We discuss other possible mechanisms underlying interim-test effects with text, including shifting to more effective encoding strategies.     

Name or hum that tune: Feeling of knowing for music

This is the first reported research that explores the feeling of knowing (FOK) for musical stimuli. Subjects attempted to recall melodies and titles of musical pieces, made FOK ratings when recall failed, and then had a recognition test. With instrumental music (Experiment 1), more titles were recalled when melodies were given as cues than vice versa. With songs whose lyrics were not presented (Experiment 2), however, more melodies were recalled than were titles. For nonrecalled items, although the overall levels of recognition did not differ, FOK ratings were higher for titles than for melodies in Experiment 1, and the opposite pattern occurred in Experiment 2. In both experiments, the FOK ratings predicted melody recognition more accurately than they did title recognition.     

Talking about visually perceived events: Communication effects on eyewitness memory

Communicators' tuning of a message about a social target to their audience's evaluation can shape their representation of the target. This audience‐tuning effect has been demonstrated with ambiguous text passages as input material. We examined whether the effect also occurs when communicators learn about the target's behaviours from visual (nonverbal) input material. In Experiment 1, participants watched a soundless video depicting ambiguous behaviours of a target, described the video to an audience who liked (vs. disliked) the target, and subsequently recalled the video. Both message and recall were biased towards the audience's judgement. In Experiment 2, the video depicted a forensically relevant event, specifically ambiguous behaviours of two persons involved in a bar brawl. Participants tuned their event retellings to their audience's responsibility judgement and remembered the event accordingly. In both experiments, the effect of the audience's judgement on recall was statistically mediated by the extent to which the message was tuned to the audience. The more participants experienced a shared reality with their audience the stronger was the message‐recall correlation (Experiment 2). We conclude that the audience‐tuning effect for visually perceived information depends on the communicators' creation of a shared reality with their audience.

Text repetition and text integration

Two experiments explored the levels of text representation that mediate text repetition effects, following the Raney (2003) model. The magnitude of the repetition benefit in Experiment 1 supported predictions of Raney's model, indicating that the ease of forming a situation model contributed to the magnitude of the reprocessing benefit. In addition, representations organized around a good situation model were more sensitive to changes than were representations formed from reading without a good situation model. The results of Experiment 2 did not support the suggestion that the surface form and textbase are bound to a well-developed situation model, thereby limiting repetition effects to similar linguistic contexts. Rather, the nature of the repetition benefits in the present series of experiments are better explained by the degree o foverlap between passages at eachof the three levels of text representation.     

Children's memory for complex autobiographical events: does spacing of repeated instances matter?

Often, when children testify in court they do so as victims of a repeated offence and must report details of an instance of the offence. One factor that may influence children's ability to succeed in this task concerns the temporal distance between presentations of the repeated event. Indeed, there is a substantial amount of literature on the "spacing effect" that suggests this may be the case. In the current research, we examined the effect of temporal spacing on memory reports for complex autobiographical events. Children participated in one or four play sessions presented at different intervals. Later, children were suggestively questioned, and then participated in a memory test. Superior recall of distributed events (a spacing effect) was found when the delay to test was 1 day (Experiment 1) but there was little evidence for a spacing effect when the delay was 1 week (Experiment 2). Implications for understanding children's recall of repeated autobiographical events are discussed.     

The interactive effects of prior knowledge and text structure on memory for cognitive psychology texts

Background: Interest in the interactive effects of prior knowledge and text structure on learning from text is increasing but experimental manipulations of knowledge and structure variables often produce findings that do not help teachers to select expository texts for students. Aims: We aimed to extend the ecological validity of previous findings by asking students with a high or low level of discipline‐relevant knowledge to read texts characteristic of those they would normally encounter. A compensation effect was hypothesized, where high prior knowledge would compensate for a lack of text structure and text structure would compensate for a lack of prior knowledge. Samples: One hundred and ninety‐five undergraduate psychology students (144 Year 1 students and 51 Year 3 students) were allocated to a high knowledge (HiPK) or low knowledge (LoPK) group on the basis of their performance on a word association test. Methods: Participants were randomly assigned to one of five text structure groups (compare/contrast, sequence, classification, enumeration, generalization) and asked to study two cognitive psychology passages before recalling the main points of the text immediately afterwards and after a delay of 2 weeks. The five text structures were placed on an ‘organizational continuum’ according to the degree of structure/organization in the 10 passages. Results: A compensation effect did not emerge. Recall was high when texts were well structured and readers had prior knowledge, but recall was poor when texts were less structured, regardless of the level of prior knowledge. Conclusions: Readers benefit most from texts that challenge pre‐existing mental representations.     

The effect of forced recall on illusory recollection in younger and older adults

The effect of an initial forced recall test on later recall and recognition tests was examined in younger and older adults. Subjects were presented with categorized word lists and given an initial test under standard cued recall instructions (with a warning against guessing) or forced recall instructions (that required guessing); subjects were later given a cued recall test for the original list items. In 2 experiments, initial forced recall resulted in higher levels of illusory memories on subsequent tests (relative to initial cued recall), especially for older adults. Older adults were more likely to say they remembered rather than knew that forced guesses had occurred in the original study episode. The effect persisted despite a strong warning against making errors in Experiment 2. When a source monitoring test was given, older adults had more difficulty than younger adults in identifying the source of items they had originally produced as guesses. If conditions encourage subjects to guess on a first memory test, they are likely to recollect these guesses as actual memories on later tests. This effect is exaggerated in older adults, probably because of their greater source monitoring difficulties. Both dual process and source monitoring theories provide insight into these findings.     

Correcting socially introduced false memories: The effect of re-study

This study examined whether participants could utilize re-study and perceptual elaboration to correct erroneous suggestions from their partner in the social contagion of memory paradigm. Participants studied household scenes and then collaboratively recalled the scenes with a confederate who interjected erroneous items. Before completing subsequent individual recall and recognition tests, participants were allowed to re-study the original items and/or to generate perceptual details of the items. Across two experiments, participants who re-studied the original material were less likely to incorporate the confederate's misleading suggestions. Re-study reduced false recall and recognition and increased veridical recall and recognition (Experiment 1) and the effect was especially pronounced with longer re-study episodes (Experiment 2). Items generated on the perceptual elaboration test offered no corrective benefit above and beyond the effects of re-study. These data demonstrate that participants can rely on self-initiated correction processes engaged during re-study to reduce socially suggested false memories.     

Retention of word pairs as a function of level of processing,instruction to remember,and delay

ABSTRACT

Modern research on the efficacy of levels of processing (LoP) tasks on memory has focused on less than 1-day retention delays, while assuming that the observed benefits of deep tasks will continue across remote delays. However, direct tests of the continued benefits of deep processes for accuracy and organisation in remote memory are rare. The current set of experiments, using auditorily-presented lists of scrambled word pairs, tested whether deep LoP tasks produced better free recall and organisation over one week (Experiment 1) and four weeks (Experiments 2 and 3). All experiments revealed significant LoP effects on free recall and organisation at immediate and delayed test, with no effect of intention to remember. However, Experiments 2 and 3 revealed poor recall and organisation at the delayed tests among all of the LoP groups, suggesting that deep processing may not produce highly accessible memories over very long delays.     

Children's memory for complex autobiographical events: Does spacing of repeated instances matter?

Often, when children testify in court they do so as victims of a repeated offence and must report details of an instance of the offence. One factor that may influence children's ability to succeed in this task concerns the temporal distance between presentations of the repeated event. Indeed, there is a substantial amount of literature on the “spacing effect” that suggests this may be the case. In the current research, we examined the effect of temporal spacing on memory reports for complex autobiographical events. Children participated in one or four play sessions presented at different intervals. Later, children were suggestively questioned, and then participated in a memory test. Superior recall of distributed events (a spacing effect) was found when the delay to test was 1?day (Experiment 1) but there was little evidence for a spacing effect when the delay was 1 week (Experiment 2). Implications for understanding children's recall of repeated autobiographical events are discussed.     

Odour and Proustian memory: reduction of context‐dependent forgetting and multiple forms of memory

In Experiment 1, the reintroduction of the same ambient odour (lemon or lavender) improved performance four weeks later in both free recall and recognition of a word list. This was a cross‐over design that allowed direct comparison between congruent and incongruent odour conditions. A further comparison with an additional group showed that memory was not improved by the presence of a different odour. Experiment 2 investigated the effect of two odour cues (lemon and lavender) in the same cross‐over design using three learning and memory tests: (1) free recall of a word list; (2) problem solving; and (3) spatial learning. While recall of the word list and spatial learning were best when the same odour was present at both learning and test, there was no such context‐dependent effect for the problem‐solving task. However, the presence of the lavender odour at test improved performance in the problem‐solving task, irrespective of the odour present at the first exposure. Thus although lavender had some effect on problem solving, we saw context‐dependent retrieval only in free recall and spatial learning. We discuss the implications of this dissociation.

Examining the testing effect with open‐ and closed‐book tests

Two experiments examined the testing effect with open‐book tests, in which students view notes and textbooks while taking the test, and closed‐book tests, in which students take the test without viewing notes or textbooks. Subjects studied prose passages and then restudied or took an open‐ or closed‐book test. Taking either kind of test, with feedback, enhanced long‐term retention relative to conditions in which subjects restudied material or took a test without feedback. Open‐book testing led to better initial performance than closed‐book testing, but this benefit did not persist and both types of testing produced equivalent retention on a delayed test. Subjects predicted they would recall more after repeated studying, even though testing enhanced long‐term retention more than restudying. These experiments demonstrate that the testing effect occurs with both open‐ and closed‐book tests, and that subjects fail to predict the effectiveness of testing relative to studying in enhancing later recall.
