Source-constrained recall: Front-end and back-end control of retrieval quality.
Research on the strategic regulation of memory accuracy has focused primarily on monitoring and control processes used to edit out incorrect information after it is retrieved (back-end control). Recent studies, however, suggest that rememberers also enhance accuracy by preventing the retrieval of incorrect information in the first place (front-end control). The present study put forward and examined a mechanism called source-constrained recall (cf. Jacoby, Shimizu, Velanova, & Rhodes, 2005) by which rememberers process and use recall cues in qualitatively different ways, depending on the manner of original encoding. Results of 2 experiments in which information about source encoding depth was made available at test showed that when possible, participants constrained recall to the solicited targets by reinstating the original encoding operations on the recall cues. This reinstatement improved the quality of the information that came to mind, which, together with improved postretrieval monitoring, enhanced actual recall performance.

Memory as discrimination: A challenge to the encoding–retrieval match principle.
Four experiments contrasted the predictions of a general encoding–retrieval match hypothesis with those of a view claiming that the distinctiveness of the cue–target relationship is the causal factor in retrieval. In Experiments 1, 2, and 4 participants learned the relationships between 4 targets and trios of cues; in Experiment 3 there were 3 targets, each associated with a pair of cues. A learning phase was followed by a cued-recognition task where the correct target had to be identified based on 1 or more of the cues. The main performance measurement was response time. Learning was designed to lead to high accuracy so effects could be attributed to retrieval efficiency rather than to variations in encoding. The nature of the cues and targets was varied across experiments. The critical factor was whether each cue was uniquely associated with the to-be-recalled target. All experiments orthogonally manipulated (a) how discriminative—or uniquely associated with a target—each cue was and (b) the degree of overlap between the cues present during learning and those present at retrieval. The novel finding reported here is that increasing the encoding–retrieval match can hinder performance if the increase simultaneously reduces how well cues predict a target—that is, a cue's diagnostic value. Encoding–retrieval match was not the factor that determined the effectiveness of retrieval. Our findings suggest that increasing the encoding–retrieval match can lead to no change, an increase, or a decrease in retrieval performance.

Reflections of distraction in memory: Transfer of previous distraction improves recall in younger and older adults.
Three studies explored whether younger and older adults' free recall performance can benefit from prior exposure to distraction that becomes relevant in a memory task. Participants initially read stories that included distracting text. Later, they studied a list of words for free recall, with half of the list consisting of previously distracting words. When the memory task was indirect in its use of distraction (Study 1), only older adults showed transfer, with better recall of previously distracting compared with new words, which increased their recall to match that of younger adults. However, younger adults showed transfer when cued about the relevance of previous distraction both before studying the words (Study 2) and before recalling the words (Study 3) in the memory test. Results suggest that both younger and older adults encode distraction, but younger adults require explicit cueing to use their knowledge of distraction. In contrast, older adults transfer knowledge of distraction in both explicitly cued and indirect memory tasks. Results are discussed in terms of age differences in inhibition and source-constrained retrieval. (PsycINFO Database Record (c) 2011 APA, all rights reserved)
Semantic processing in the production of numerals across notations.
In the present work, we conducted a series of experiments to explore the processing stages required to name numerals presented in different notations. To this end, we used the semantic blocking paradigm previously used in psycholinguist studies. We found a facilitative effect of the semantic blocked context relative to the mixed context for Arabic digits and number words. However, the blocked context produced an interference effect for physical numerosity and Roman numbers. Our results provided further evidence to models suggesting that Arabic digits may be named through an asemantic route similar to that of number words, whereas a semantic route is mandatory to name physical numerosity and Roman numerals.

Success modulates consolidation of a visuomotor adaptation task.
Consolidation is a time-dependent process that is responsible for the storage of information in long-term memory. As such, it plays a crucial role in motor learning. Prior research suggests that some consolidation processes are triggered only when the learner experiences some success during practice. In the present study, we tested whether consolidation processes depend on the objective performance of the learner or on the learner's subjective evaluation of his or her own performance (i.e., how successful the learner believes he or she is). Four groups of participants performed 2 sessions of a visuomotor adaptation task for which they had to learn a new internal model of limb kinematics; these sessions were either 5 min or 24 hr apart. The task was identical for all participants, but each group was given a difficult or an easy objective that affected the participants' evaluation of their own performance during the initial practice session. All groups adapted their movements similarly to the rotation of the visual feedback during the first session. However, when retested the following day, participants who had a 24-hr rest interval and had initially experienced success performed significantly better than those who did not feel successful or who were given a 5-min rest interval. Our results indicate that a certain level of subjective success must be experienced to trigger certain consolidation processes. (PsycINFO Database Record (c) 2011 APA, all rights reserved)
Independent influences of verbalization and race on the configural and featural processing of faces: A behavioral and eye movement study.
Describing a face in words can either hinder or help subsequent face recognition. Here, the authors examined the relationship between the benefit from verbally describing a series of faces and the same-race advantage (SRA) whereby people are better at recognizing unfamiliar faces from their own race as compared with those from other races. Verbalization and the SRA influenced face recognition independently, as evident on both behavioral (Experiment 1) and eye movement measures (Experiment 2). The findings indicate that verbalization and the SRA each recruit different types of configural processing, with verbalization modulating face learning and the SRA modulating both face learning and recognition. Eye movement patterns demonstrated greater feature sampling for describing as compared with not describing faces and for other-race as compared with same-race faces. In both cases, sampling of the eyes, nose, and mouth played a major role in performance. The findings support a single process account whereby verbalization can influence perceptual processing in a flexible and yet fundamental way through shifting one's processing orientation.

Discriminating famous from fictional names based on lifetime experience: Evidence in support of a signal-detection model based on finite mixture distributions.
It is widely accepted that signal-detection mechanisms contribute to item-recognition memory decisions that involve discriminations between targets and lures based on a controlled laboratory study episode. Here, the authors employed mathematical modeling of receiver operating characteristics (ROC) to determine whether and how a signal-detection mechanism contributes to discriminations between moderately famous and fictional names based on lifetime experience. Unique to fame judgments is a lack of control over participants' previous exposure to the stimuli deemed “targets” by the experimenter; specifically, if they pertain to moderately famous individuals, participants may have had no prior exposure to a substantial proportion of the famous names presented. The authors adopted established models from the recognition-memory literature to examine the quantitative fit that could be obtained through the inclusion of signal-detection and threshold mechanisms for two data sets. They first established that a signal-detection process operating on graded evidence is critical to account for the fame judgment data they collected. They then determined whether the graded memory evidence for famous names would best be described with one distribution with greater variance than that for the fictional names, or with two finite mixture distributions for famous names that correspond to items with or without prior exposure, respectively. Analyses revealed that a model that included a d' parameter, as well as a mixture parameter, provided the best compromise between number of parameters and quantitative fit. Additional comparisons between this equal-variance signal-detection mixture model and a dual-process model, which included a high-threshold process in addition to a signal-detection process, also favored the former model. In support of the conjecture that the mixture parameter captures participants' prior experience, the authors found that it was increased when the analysis was restricted to names in occupational categories for which participants indicated high exposure.

Are pictures good for learning new vocabulary in a foreign language? Only if you think they are not.
The current study explored whether new words in a foreign language are learned better from pictures than from native language translations. In both between-subjects and within-subject designs, Swahili words were not learned better from pictures than from English translations (Experiments 1–3). Judgments of learning revealed that participants exhibited greater overconfidence in their ability to recall a Swahili word from a picture than from a translation (Experiments 2–3), and Swahili words were also considered easier to process when paired with pictures rather than translations (Experiment 4). When this overconfidence bias was eliminated through retrieval practice (Experiment 2) and instructions warning participants to not be overconfident (Experiment 3), Swahili words were learned better from pictures than from translations. It appears, therefore, that pictures can facilitate learning of foreign language vocabulary—as long as participants are not too overconfident in the power of a picture to help them learn a new word.

Aging and retrospective revaluation of causal learning.
In a 2-stage causal learning task, young and older participants first learned which foods presented in compound were followed by an allergic reaction (e.g., STEAK–BEANS→ REACTION) and then the causal efficacy of 1 food from these compounds was revalued (e.g., BEANS→ NO REACTION). In Experiment 1, unrelated food pairs were used, and although there were no age differences in compound- or single-cue–outcome learning, older adults did not retrospectively revalue the causal efficacy of the absent target cues (e.g., STEAK). However, they had weaker within–compound associations for the unrelated foods, and this may have prevented them from retrieving the representations of these cues. In Experiment 2, older adults still showed no retrospective revaluation of absent cues even though compound food cues with pre-existing associations were used (e.g., STEAK–POTATO), and they received additional learning trials. Finally, in Experiment 3, older adults revalued the causal efficacy of the target cues when small, unobtrusive icons of these cues were present during single-cue revaluation. These findings suggest that age-related deficits in causal learning for absent cues are due to ineffective associative binding and reactivation processes.

Retrieval-induced forgetting of arithmetic facts.
Retrieval-induced forgetting (RIF) is a widely studied phenomenon of human memory, but RIF of arithmetic facts remains relatively unexplored. In 2 experiments, we investigated RIF of simple addition facts (2 + 3 = 5) from practice of their multiplication counterparts (2 × 3 = 6). In both experiments, robust RIF expressed in response times occurred only for high-strength small-number addition facts with sums ≤ 10, indicating that RIF from multiplication practice was interference dependent. RIF of addition-fact memory was produced by multiplication retrieval (2 × 3 = ?) but not multiplication study (2 × 3 = 6), supporting an inhibitory mechanism of RIF in arithmetic memory. Finally, RIF occurred with multiplication practiced in word format (three × four) and addition tested later in digit format (3 + 4), which provides evidence that digit and written-word formats for arithmetic accessed a common semantic retrieval network. The results support the view that addition and multiplication facts are stored in an interrelated semantic network and that RIF of competing addition facts is an intrinsic process of multiplication fact retrieval.

Binary ROCs in perception and recognition memory are curved.
In recognition memory, a classic finding is that receiver operating characteristics (ROCs) are curvilinear. This has been taken to support the fundamental assumptions of signal detection theory (SDT) over discrete-state models such as the double high-threshold model (2HTM), which predicts linear ROCs. Recently, however, Bröder and Schütz (2009) challenged this argument by noting that most of the data on which support for SDT is based have involved confidence ratings. The authors argued that certain types of rating scale usage may result in curved ROCs even if the generating process is thresholded in nature. From this point of view, only ROCs constructed via experimental bias manipulations are useful for discriminating between the models. Bröder and Schütz conducted a meta-analysis and new experiments that compared SDT and the 2HTM using binary (yes–no) ROCs and found that many of these functions were linear, supporting 2HTM over SDT. We examine all the data reported by Bröder and Schütz, noting important limitations in their methodology, analyses, and conclusions. We report a new meta-analysis and 2 new experiments to examine the issue more closely while avoiding the limitations of Bröder and Schütz's study. These new data indicate that binary ROCs are curved in recognition, consistent with previous findings in perception and reasoning. Our results support classic arguments in favor of SDT and indicate that curvature in ratings ROCs is not task specific. We recommend the ratings procedure and suggest that analyses based on threshold models be treated with caution. (PsycINFO Database Record (c) 2011 APA, all rights reserved)
Not all skilled readers have cracked the code: Individual differences in masked form priming.
This experiment investigated whether individual differences in written language proficiency among university students predict the early stages of lexical retrieval tapped by the masked form priming lexical decision task. To separate the contributions of sublexical facilitation and lexical competition to masked form priming, the effects of prime lexicality were directly compared for both transposed-letter (TL) primes (e.g., sung SNUG; salb SLAB ) and neighbor primes (e.g., snag SNUG; sleb SLAB ) in a sample of 100 university students assessed on measures of reading, spelling and vocabulary. The data for the whole sample showed facilitation from nonword primes, but inhibition from word primes. Linear mixed models including the individual difference measures showed that higher scores on a principal component that captured the shared variance among reading, spelling, and vocabulary were associated with both stronger inhibition from TL word primes and stronger facilitation from neighbor nonword primes. These findings are consistent with the lexical quality hypothesis of reading that predicts that skilled readers vary in the extent to which they have developed precisely specified orthographic representations.

Broken expectations: Violation of expectancies, not novelty, captures auditory attention.
The role of memory in behavioral distraction by auditory attentional capture was investigated: We examined whether capture is a product of the novelty of the capturing event (i.e., the absence of a recent memory for the event) or its violation of learned expectancies on the basis of a memory for an event structure. Attentional capture—indicated by disruption of a focal visually presented serial recall task—was found when the voice conveying a concurrent irrelevant auditory sequence changed every 5 recall trials (from male to female or vice versa). There was no evidence of attentional capture when the irrelevant sequence was first encountered and hence novel; capture occurred only when an expectation for a particular voice had been learned and then violated. Furthermore, with the increasing predictability of (and hence expectancy for) the voice changes across the experimental session, the capture response diminished only to be reinstated when that session-wide expectation was itself violated by a break in the change-every-5-trials pattern. The results highlight the critical role of learned expectations, as opposed to novelty detection, in behavioral auditory attentional capture.

Memory inhibition, aging, and the executive deficit hypothesis.
Although memory inhibition seems to underlie retrieval-induced forgetting (RIF), there is some controversy about the precise nature of this effect. Because normal RIF is observed in people with deficits in executive control (i.e., older adults), some have proposed that an automatic-like inhibitory process is responsible for the effect. On the contrary, neurocognitive and dual-task findings with young people support the view that an executive control process underlies RIF. In the present study, we address this apparent controversy by comparing young and older participants under different dual-task conditions. Our results indicate that memory inhibition in older adults also depends on executive control, which is more easily disrupted by a secondary task in older than in young adults. Thus, the fact that RIF in older adults is sometimes present is not incompatible with a decline in executive control with aging. The results also shed some light into the discussion regarding the effect of dual tasking on retrieval. (PsycINFO Database Record (c) 2011 APA, all rights reserved)
Consistency of handedness, regardless of direction, predicts baseline memory accuracy and potential for memory enhancement.
Research has shown that consistently right-handed individuals have poorer memory than do inconsistently right- or left-handed individuals under baseline conditions but more reliably exhibit enhanced memory retrieval after making a series of saccadic eye movements. From this it could be that consistent versus inconsistent handedness, regardless of left/right direction, is an important individual difference factor in memory. Or, more specifically, it could be the presence or absence of consistent right-handedness that matters for memory. To resolve this ambiguity, we compared consistent and inconsistent left- and right-handers on associative recognition tests taken after saccades or a no-saccades control activity. Consistent-handers exhibited poorer memory than did inconsistent-handers following the control activity, and saccades enhanced retrieval for consistent-handers only. Saccades impaired retrieval for inconsistent-handers. None of these effects depended on left/right direction. Hence, this study establishes handedness consistency, regardless of direction, as an important individual difference factor in memory. (PsycINFO Database Record (c) 2011 APA, all rights reserved)
How the measurement of memory processes can affect memory performance: The case of remember/know judgments.
Relatively little attention has been paid thus far in memory research to the effects of measurement instruments intended to assess memory processes on the constructs being measured. The current article investigates the influence of employing the popular remember/know (R/K) measurement procedure on memory performance itself. This measurement procedure was extensively used in the past to assess the respective contributions of 2 processes to memory judgments, one based on familiarity and the other on recollection. Two experiments using unrelated word pairs showed that the use of an R/K procedure can alter memory performance. Specifically, the R/K procedure improved associative memory among older but not younger adults compared to conditions in which participants were not asked to provide R/K judgments. Such an effect was not observed in item memory performance. Potential mechanisms mediating these differential memory measurement effects are outlined, and the measurement effects' implications for memory and cognitive research are discussed.

Dividing attention lowers children's but increases adults' false memories.
The present study examined the impact of divided attention on children's and adults' neutral and negative true and false memories in a standard Deese/Roediger–McDermott paradigm. Children (7- and 11-year-olds; n = 126) and adults (n = 52) received 5 neutral and 5 negative Deese/Roediger–McDermott word lists; half of each group also received a divided attention task. The results showed that divided attention affected children's and adults' false memory levels differently but did not alter true memory differently. Our results revealed a developmental shift in that divided attention lowered children's false memory rates but increased adults' false memory rates, regardless of the nature of the material (i.e., neutral or negative). Our study indicates that manipulations that target conscious processing (e.g., divided attention) result in marked qualitative and quantitative differences between children's and adults' false memories but not true memories.

Reasoning about other people's beliefs: Bilinguals have an advantage.
Bilingualism can have widespread cognitive effects. In this article we investigate whether bilingualism might have an effect on adults' abilities to reason about other people's beliefs. In particular, we tested whether bilingual adults might have an advantage over monolingual adults in false-belief reasoning analogous to the advantage that has been observed with bilingual children. Using a traditional false-belief task coupled with an eye-tracking technique, we found that adults in general suffer interference from their own perspective when reasoning about other people's beliefs. However, bilinguals are reliably less susceptible to this egocentric bias than are monolinguals. Moreover, performance on the false-belief task significantly correlated with performance on an executive control task. We argue that bilinguals' early sociolinguistic sensitivity and enhanced executive control may account for their advantage in false-belief reasoning.

Dynamic search and working memory in social recall.
What are the mechanisms underlying search in social memory (e.g., remembering the people one knows)? Do the search mechanisms involve dynamic local-to-global transitions similar to semantic search, and are these transitions governed by the general control of attention, associated with working memory span? To find out, we asked participants to recall individuals from their personal social networks and measured each participant's working memory capacity. Additionally, participants provided social-category and contact-frequency information about the recalled individuals as well as information about the social proximity among the recalled individuals. On the basis of these data, we tested various computational models of memory search regarding their ability to account for the patterns in which participants recalled from social memory. Although recall patterns showed clustering based on social categories, models assuming dynamic transitions between representations cued by social proximity and frequency information predicted participants' recall patterns best—no additional explanatory power was gained from social-category information. Moreover, individual differences in the time between transitions were positively correlated with differences in working memory capacity. These results highlight the role of social proximity in structuring social memory and elucidate the role of working memory for maintaining search criteria during search within that structure.

What factors underlie associative and categorical memory illusions? The roles of backward associative strength and interitem connectivity.
Factors that affect categorical and associative false memory illusions were investigated in 2 experiments. In Experiment 1, backward associative strength (BAS) from the list word to the critical lure and interitem connectivity were manipulated in Deese–Roediger–McDermott (DRM) and category list types. For both recall and recognition tasks, the likelihood of producing DRM and category false memories was greater for lists with high BAS and low interitem connectivity. In Experiment 2, DRM and category lists with high BAS showed similar indirect priming effects in a word stem completion task. With low BAS, category lists, unlike DRM lists, showed no priming effect. We discuss the role of BAS, interitem connectivity, and associate-level differences in implicit and explicit measures of false memory production.

Familiarity and personal experience as mediators of recall when planning for future contingencies.
In this article, we demonstrate that planning tasks enhance recall when the context of planning (a) is self-referential and (b) draws on familiar scenarios represented in episodic memory. Specifically, we show that when planning tasks are sorted according to the degree to which they evoke memories of personally familiar scenarios (e.g., planning a picnic), recall is reliably superior to tasks that fail to do so (e.g., planning an Arctic trek). We discuss the implications of these findings for planning tasks and their relation to episodic memory. (PsycINFO Database Record (c) 2011 APA, all rights reserved)
At the same time or apart in time? The role of presentation timing and retrieval dynamics in generalization.
Several bodies of research have found different results with regard to presentation timing, categorization, and generalization. Both presenting instances at the same time (simultaneous) and presenting instances apart in time (spacing) have been shown to facilitate generalization. In this study, we resolved these results by examining simultaneous, massed, and spaced presentations in 2-year-old children's (N = 144) immediate and long-term performance on a novel noun generalization task. Results revealed that, when tested immediately, children in the simultaneous condition outperformed children in all other conditions. However, when tested after 15 min, children in the spaced condition outperformed children in all other conditions. Results are discussed in terms of how retrieval dynamics during learning affect abstraction, retention, and generalization across time. (PsycINFO Database Record (c) 2011 APA, all rights reserved)
Dissociation of short-term forgetting from the passage of time.
In many theories, forgetting is closely linked to the passage of time. In the present experiments, recall in a short-term memory task was less accurate when the retention interval included a difficult arithmetic addition task, compared with an easy task. In a novel condition, the interfering task was switched from hard to easy partway through the retention interval. Recall accuracy at long retention intervals recovered from the level consistent with the hard interfering task to a more accurate level consistent with an easy interfering task. Such recovery is not in agreement with theories that link forgetting to the passage of time, such as trace decay. The reversed forgetting functions are more consistent with an account in which different levels of nonspecific retroactive interference in the retention interval just before the time of retrieval influence different levels of performance accuracy. With the uncoupling of interference levels from time, forgetting is dissociated from the passage of time. (PsycINFO Database Record (c) 2011 APA, all rights reserved)
