Reading text aloud benefits memory but not comprehension.

The production effect-that reading aloud leads to better memory than does reading silently-has been defined narrowly with reference to memory; it has been explored largely using word lists as the material to be read and remembered. But might the benefit of production extend beyond memory and beyond individual words? In a series of four experiments, passages from reading comprehension tests served as the study material. Participants read some passages aloud and others silently. After each passage, they completed multiple-choice questions about that passage. Separating the multiple-choice questions into memory-focused versus comprehension-focused questions, we observed a consistent production benefit only for the memory-focused questions. Production clearly improves memory for text, not just for individual words, and also extends to multiple-choice testing. The overall pattern of findings fits with the distinctiveness account of production-that information read aloud stands out at study and at test from information read silently. Only when the tested information is a very close match to the studied information, as is the case for memory questions but not for comprehension questions, does production improve accuracy.

EEG-based univariate and multivariate analyses reveal that multiple processes contribute to the production effect in recognition.

The production effect (PE) is the finding that reading words aloud rather than silently during study leads to improved memory. We used electroencephalography (EEG) techniques to detect the contributions of recollection, familiarity, and attentional processes to the PE in recognition memory, using Chinese stimuli. During the study phase, participants encoded each list item aloud, silently, or by performing a non-unique aloud (control) task. During the test phase, they made remember/know/new recognition judgments. We recorded EEG data in both phases. The behavioral results replicated the typical pattern with English stimuli: Recognition was better in the aloud condition than in the silent (and control) condition, and this PE was due to enhanced recollection and familiarity. At study, the amplitude of the P3b ERP component was greater in the aloud than in the silent/control conditions, suggesting that reading aloud increases attention or preparatory processing during the intention phase. At test, the recollection-based LPC old/new effect was largest in the aloud condition; however, the familiarity-based FN400 old/new effect was equivalent between the aloud condition and the silent/control conditions. Only the LPC effect correlated with the behavioral effect. Moreover, multivariate pattern analysis (MVPA) showed that accurate classification of items as 'aloud' versus 'new' mainly occurred in the later period of the recognition response, consistent with the LPC old/new effect. Our findings suggest that the within-subject PE in recognition memory reflects enhanced attention and distinctiveness, rather than increased memory strength. More broadly, our findings suggest that encoding strategies such as production enhance recollection more than familiarity.

Recognition, remember-know, and confidence judgments: no evidence of cross-contamination here!

ABSTRACTWe report three experiments designed to reveal the mechanisms that underlie subjective experiences of recognition by examining effects of how those experiences are measured. Prior research has explored the potential influences of collecting metacognitive measures on memory performance. Building on this work, here we systematically evaluated whether cross-measure contamination occurs when remember-know (RK) and/or confidence (C) judgments are made after old/new recognition decisions. In Experiment 1, making either RK or C judgments did not significantly influence recognition relative to a standard no-judgment condition. In Experiment 2, making RK judgments in addition to C judgments did not significantly affect recognition or confidence. In Experiment 3, making C judgments in addition to RK judgments did not significantly affect recognition or patterns of RK responses. Cross-contamination was not apparent regardless of whether items were studied using a shallow or deep levels-of-processing task - a manipulation that yielded robust effects on recognition, RK judgments, and C. Our results indicate that under some conditions, participants can independently evaluate their recognition, subjective recognition experience, and confidence. Though contamination across measures of metamemory and memory is always possible, it may not be inevitable. This has implications for the mechanisms that underlie subjective experiences that accompany recognition judgments.

Production can enhance semantic encoding: Evidence from forced-choice recognition with homophone versus synonym lures.

The production effect-better memory for words read aloud rather than silently-has been attributed to responses at test being guided by memory for the act of production. In Experiment 1, we evaluated this distinctiveness account by comparing production effects in forced-choice recognition when lures were either homophones of the targets (toad or towed?) or unrelated words (toad or seam?). If the production effect at test was driven solely by memory for the productive act (e.g., articulation, auditory processing), then the effect should be reduced with homophone lures. Contrary to that prediction, the production effect did not differ credibly between homophone-lure and unrelated-lure groups. Experiment 1 led us to hypothesize that production may also boost semantic encoding, and that participants use memory of semantic encoding to guide their forced-choice responses. Consistent with these hypotheses, using synonym lures to interfere with semantic-based decisions (poison or venom?) reduced the production effect relative to using unrelated lures (poison or ethics?) in Experiment 2. Our findings suggest that enhanced conceptual encoding may be another useful product of production.

Pupil dilation during recognition reflects the subjective recollection/familiarity experience at test rather than the level of processing at encoding.

Pupil dilation provides a window into recognition memory processes. During a recognition test, the pupil dilates more in response to a recognized studied item than to a correctly rejected new item. Various explanations for this pupil old/new effect have been offered. By a retrieval effort account, the pupil's response on a recognition test reflects the cognitive effort needed to retrieve items from memory. By a memory strength account, pupil dilation reflects the strength of the subjective memory experience elicited by items at test. To compare these accounts, we varied levels of processing (LOP) at study, then measured pupil dilation on a delayed recognition test during which participants made recollection/familiarity judgements. Pupil dilation at test was similar whether test items had been studied in a deep or shallow LOP task, but was greater when deep, shallow, and new test items were experienced as recollected rather than as familiar. This pattern supports the memory strength account rather than the retrieval effort account of pupil dilation during a recognition test. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Neural correlates of the production effect: An fMRI study.

Recognition memory is improved for items produced at study (e.g., by reading them aloud) relative to a non-produced control condition (e.g., silent reading). This production effect is typically attributed to the extra elements in the production task (e.g., motor activation, auditory perception) enhancing item distinctiveness. To evaluate this claim, the present study examined the neural mechanisms underlying the production effect. Prior to a recognition memory test, different words within a study list were read either aloud, silently, or while saying "check" (as a sensorimotor control condition). Production improved recognition, and aloud words yielded higher rates of both recollection and familiarity judgments than either silent or control words. During encoding, fMRI revealed stronger activation in regions associated with motor, somatosensory, and auditory processing for aloud items than for either silent or control items. These activations were predictive of recollective success for aloud items at test. Together, our findings are compatible with a distinctiveness-based account of the production effect, while also pointing to the possible role of other processing differences during the aloud trials as compared to silent and control.

Distinctive encoding of a subset of DRM lists yields not only benefits, but also costs and spillovers.

Prior research has emphasized that performing distinctive encoding on a subset of lists in the DRM paradigm suppresses false recognition; we show that its benefits can be mitigated by costs and spillover effects. Within groups read half the DRM lists and solved anagrams for the other half using a strategy that emphasized either item-specific or relational processing. Their recognition was compared to three pure-list control groups (read, item-specific generation, relational generation). Correct recognition in the within groups showed a benefit for generate items and a cost for read items, resulting in little net improvement relative to pure reading. False recognition in the within groups was reduced following item-specific vs. relational generation, but there was again little net improvement. Most surprisingly, false recognition in the within groups was greater for generate than read lists. This pattern suggests that relational processing of read lists spilled over to generate lists, boosting false recognition for generate lists. Distinctive encoding of a subset of items does not appear to globally improve memory accuracy.

Reducing False Recognition in the Deese-Roediger/McDermott Paradigm: Related Lures Reveal How Distinctive Encoding Improves Encoding and Monitoring Processes.

In the Deese-Roediger/McDermott (DRM) paradigm, distinctive encoding of list items typically reduces false recognition of critical lures relative to a read-only control. This reduction can be due to enhanced item-specific processing, reduced relational processing, and/or increased test-based monitoring. However, it is unclear whether distinctive encoding reduces false recognition in a selective or global manner. To examine this question, participants studied DRM lists using a distinctive item-specific anagram generation task and then completed a recognition test which included both DRM critical lures and either strongly related lures (Experiment 1) or weakly related lures (Experiment 2). Compared to a read-control group, the generate groups showed increased correct recognition and decreased false recognition of all lure types. We then estimated the separate contributions of encoding and retrieval processes using signal-detection indices. Generation improved correct recognition by both increasing encoding of memory information for list words and by increasing memory monitoring at test. Generation reduced false recognition by reducing the encoding of memory information and by increasing memory monitoring at test. The reduction in false recognition was equivalent for critical lures and related lures, indicating that generation globally reduces the encoding of related non-presented items at study (not just critical lures), while globally increasing list-theme-based monitoring at test.

Comparing recollection and nonrecollection memory states for recall of general knowledge: A nontrivial pursuit.

Based on the classic distinction between semantic and episodic memory, people answer general-knowledge questions by querying their semantic memory. And yet, an appeal of trivia games is the variety of memory experiences they arouse-including the recollection of episodic details. We report the first in-depth exploration of the memory states that arise for recalled answers to general-knowledge questions. In 2 experiments, participants classified their answers as learning memory or related memory forms of recollection, as feels familiar or just know forms of nonrecollection, or as a guess. A recollection state was reported for nearly half of the correct answers. Learning memory, related memory, and just know states showed similarly high accuracy and confidence-whereas the feels familiar state was much lower. The differences between familiarity and knowing highlight the importance of distinguishing these oft-conflated states. Our study establishes that episodic memory often contributes to retrieval of general-knowledge, and that the memory states arising during retrieval can be diagnostic of accuracy.

Improving the Reporting of Young Children's Food Intake: Insights from a Cognitive Interviewing Study with Mothers of 3-7-Year Old Children.

Short food questions (SFQ) allow for rapid reporting of food intake across a variety of settings but are limited by poor validity and reliability. Understanding the recall process used by parents to report children's food intake can improve question design and psychometric performance. This study aimed to improve understanding of how parents report children's dietary intake using SFQ. Semi-structured, cognitive interviews were conducted with 21 mothers of 3-7-year-old children. Mothers were asked to 'think-aloud' while answering SFQ about their child's food intake. Thematic analysis identified themes relating to parent's question and answer process and barriers to recall. Information retrieval strategies focused on 'use-of-time' and 'sphere of food provision' and differed for core versus unhealthy foods. Recall of routine and home food provision were used to report core food intake, whereas recall of special occasions and food provision outside the home guided recall of discretionary foods. Mothers utilize different recall strategies for core and discretionary foods based on use of time and the sphere of food provision. The ease of reporting children's dietary intake may be improved by utilizing a shorter recall time frame, clear and direct question wording, and use of food examples and recall prompts.

Pure-list production improves item recognition and sometimes also improves source memory.

Relative to reading silently, reading words aloud (a type of "production") typically enhances item recognition, even when production is manipulated between groups using pure lists. We investigated whether pure-list production also enhances memory for various item details (i.e., source memory). Screen side (Experiment 1), font size (Experiment 2), or reading versus generating from anagrams (Experiments 3-4) were the sources varied within-subject, and aloud versus silent reading was varied across groups. Thus, the manipulation of source was apparent to participants, whereas the manipulation of production was not. Traditional measures and multinomial modeling established that the aloud groups generally showed improved item recognition-and showed improved source memory when steps were taken to enhance the salience of the source manipulation (Experiment 4). In summary, reading an entire list of items improves item recognition and can also improve memory for some types of source details.

The integrative memory model is detailed, but skimps on false memories and development.

The integrative memory model combines five core memory systems with an attributional system. We agree with Bastin et al. that this melding is the most novel aspect of the model. But we await further evidence that the model's substantial complexity informs our understanding of false memories or of the development of recollection and familiarity.

Protective effects of testing across misinformation formats in the household scene paradigm.

Many studies have demonstrated retrieval-enhanced suggestibility (RES), in which taking an initial recall test after witnessing an event increases suggestibility to subsequent misinformation introduced via a narrative. Recently, however, initial testing has been found to have a protective effect against misinformation introduced via cued-recall questions. We examined whether misinformation format (narrative vs. cued-recall questions) yields a similar dissociation in a paradigm that, to date, has consistently yielded a protective effect of testing (PET). After studying photos of household scenes (e.g., kitchen), some participants took an initial recall test. After a 48-hr delay, items not presented in the scenes (e.g., knives/plates) were suggested either via narrative or questions. Regardless of the misinformation format, we found a PET on both initial-test-conditionalised free recall and source-monitoring tests. However, initial testing also yielded memory costs, such that suggested items reported on the initial test were likely to persist on a final recall test. Thus, initial testing can protect against suggestibility, but can also precipitate memory errors when intrusions emerge on an initial test.

Independent recollection/familiarity ratings can dissociate: Evidence from the effects of test context on recognition of event details.

Bodner and Richardson-Champion (2007) found a dissociative effect of test context on binary remember/know judgments about a critical set of details from a film sequence. Details of medium difficulty were more likely to be judged "recollected" when preceded by a set of difficult details than a set of easy details, but were similarly likely to be judged "familiar." Using the same paradigm, we replicated this dissociation when participants independently rated recollection and familiarity. Our finding represents the first evidence that independent recollection/familiarity ratings can be dissociated. In contrast, previous studies using independent ratings have yielded parallel effects of variables that produce dissociative effects with binary judgments. Our discussion considers potential causes of this dissociation, whether test context influenced discrimination or response bias, and implications for interpreting subjective recognition experiences. Demonstrations that test context can affect recollection reports also have implications for designing and conducting eyewitness interviews.

Independent recollection-familiarity ratings: Similar effects of levels-of-processing whether amount or confidence is rated.

Independent recollection-familiarity (RF) ratings are sometimes collected to measure subjective experiences of recollection and familiarity during recognition. Although the RF ratings task purports to measure the degree to which each recognition state is experienced, the rating scale has been worded in terms of confidence rather than amount. Given prior evidence that wording influences recognition and remember/know judgments, we compared RF rating scales worded in terms of amount versus confidence across 2 groups. A robust levels-of-processing effect occurred on both recollection and familiarity ratings, and its magnitude was similar across scale wording. Scale wording did not influence recognition, and, most importantly, it had little influence on ratings of recollection and familiarity. These findings suggest that participants may use confidence to rate amount, or vice versa. Regardless, researchers should align their task instructions and scale wording, and should publish them. Such alignment and transparency is crucial for interpreting measures of the memory states that arise during recognition memory. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

Item-specific and relational processing both improve recall accuracy in the DRM paradigm.

Using the Deese-Roediger-McDermott (DRM) paradigm, Huff and Bodner found that both item-specific and relational variants of a task improved correct recognition, but only the item-specific variants reduced false recognition, relative to a read-control condition. Here, we examined the outcome pattern when memory was tested using free recall, using the same item-specific versus relational task variants across three experiments as our previous study (processing instructions, pleasantness ratings, anagram generation). The outcome pattern in recall was similar to recognition, except relational processing at study actually reduced the DRM illusion, though not as much as item-specific processing. To reconcile this task difference, we suggest that the memory information laid down during relational encoding enhances the familiarity of the critical items at test. To the extent that familiarity is used less as a basis for responding in free recall than in recognition, relational processing ironically reduces rather than increases the DRM illusion in recall.

Prediction of beauty and liking ratings for abstract and representational paintings using subjective and objective measures.

Recent research on aesthetics has challenged the adage that "beauty is in the eye of the beholder" by identifying several factors that predict ratings of beauty. However, this research has emerged in a piecemeal fashion. Most studies have examined only a few predictors of beauty, and measured either subjective or objective predictors, but not both. Whether the predictors of ratings of beauty versus liking differ has not been tested, nor has whether predictors differ for major distinctions in art, such as abstract vs. representational paintings. Finally, past studies have either relied on experimenter-generated stimuli-which likely yield pallid aesthetic experiences-or on a curation of high-quality art-thereby restricting the range of predictor scores. We report a study (N = 598) that measured 4 subjective and 11 objective predictors of both beauty ratings and liking ratings, for 240 abstract and 240 representational paintings that varied widely in beauty. A crossover pattern occurred in the ratings, such that for abstract paintings liking ratings were higher than beauty ratings, whereas for representational paintings beauty ratings were higher than liking ratings. Prediction was much better for our subjective than objective predictors, and much better for our representational than abstract paintings. For abstract paintings, liking ratings were much more predictable than beauty ratings. Implications and directions for future research are discussed.

Inducing preference reversals in aesthetic choices for paintings: Introducing the contrast paradigm.

Understanding what leads people to reverse their choices is important in many domains. We introduce a contrast paradigm for studying reversals in choices-here between pairs of abstract paintings-implemented in both within-subject (Experiment 1; N = 320) and between-subject (Experiment 2; N = 384) designs. On each trial, participants chose between a pair of paintings. A critical pair of average-beauty paintings was presented before and after either a reversal or control block. In the reversal block, we made efforts to bias preference away from the chosen average-beauty painting (by pairing it with more-beautiful paintings) and toward the non-chosen average-beauty painting (by pairing it with less-beautiful paintings). Meta-analysis revealed more reversals after reversal blocks than after control blocks, though only when the biasing manipulations succeeded. A second meta-analysis revealed that reversals were generally more likely for participants who later misidentified their initial choice, demonstrating that memory for initial choices influences later choices. Thus, the contrast paradigm has utility both for inducing choice reversals and identifying their causes.

Getting at the source of distinctive encoding effects in the DRM paradigm: evidence from signal-detection measures and source judgments.

Studying Deese-Roediger-McDermott (DRM) lists using a distinctive encoding task can reduce the DRM false memory illusion. Reductions for both distinctively encoded lists and non-distinctively encoded lists in a within-group design have been ascribed to use of a distinctiveness heuristic by which participants monitor their memories at test for distinctive-task details. Alternatively, participants might simply set a more conservative response criterion, which would be exceeded by distinctive list items more often than all other test items, including the critical non-studied items. To evaluate these alternatives, we compared a within-group who studied 5 lists by reading, 5 by anagram generation, and 5 by imagery, relative to a control group who studied all 15 lists by reading. Generation and imagery improved recognition accuracy by impairing relational encoding, but the within group did not show greater memory monitoring at test relative to the read control group. Critically, the within group's pattern of list-based source judgments provided new evidence that participants successfully monitored for distinctive-task details at test. Thus, source judgments revealed evidence of qualitative, recollection-based monitoring in the within group, to which our quantitative signal-detection measure of monitoring was blind.
