Do pictures influence memory and metamemory in Chinese vocabulary learning? Evidence from Russian and Colombian learners.

Despite the increasing interest in learning non-alphabetical languages such as Chinese, research about its learning process for alphabet users is scarce. Research conducted on Latin alphabet users on learning languages written in Latin alphabet, or on Chinese language learning in Chinese native speakers, users is undoubtedly useful but it does not inform about the peculiarities of leaning Chinese language by other alphabet users. Additionally, several authors have highlighted the need to inform and extend the current second language acquisition theories on the particular challenges of learning a language that uses another script. In this research we aim to contribute filling this research gap and studied the learning process of Chinese vocabulary by users of scripts different from Chinese. In particular, we examined the role of pictures and translations as learning aids for Chinese language vocabulary learning in participants familiarized with either one or two alphabetical scripts (different from the Chinese logographic script). One hundred thirteen participants studied word-aid pairs in different conditions: Hanzi (Chinese in Chinese characters)-picture; Pinyin (Chinese in Latin alphabet)-picture; Hanzi-translation; Pinyin-translation. Participants evaluated the future recallability of the words and their meanings (i.e., judgements of learning) and completed two recognition tests. Words in Pinyin and words-translation pairs were judged to be easier to remember than Hanzi and word-pictures pairs. Participants remembered the meaning of words written in Hanzi better than in Pinyin, and word-translations pairs better than pictures, but they were more confident about word-picture pairs. These results suggest that pictures boost confidence in learning Chinese, but do not affect performance. These findings suggest that while pictures may boost confidence in learning Chinese, they may not necessarily lead to better performance. Our study provides valuable insights into the interaction of learning aids and writing system in (meta)memory during vocabulary acquisition.

Conversational pragmatics: memory reporting strategies in different social contexts.

Previous studies in conversational pragmatics have showed that the information people share with others heavily depends on the confidence they have in the correctness of a candidate answer. At the same time, different social contexts prompt different incentive structures, which set a higher or lower confidence criterion to determine which potential answer to report. In this study, we investigated how the different incentive structures of several types of social contexts and how different levels of knowledge affect the amount of information we are willing to share. Participants answered easy, intermediate, and difficult general-knowledge questions and decided whether they would report or withhold their selected answer in different social contexts: formal vs. informal, that could be either constrained (a context that promotes providing only responses we are certain about) or loose (with an incentive structure that maximizes providing any type of answer). Overall, our results confirmed that social contexts are associated with different incentive structures which affects memory reporting strategies. We also found that the difficulty of the questions is an important factor in conversational pragmatics. Our results highlight the relevance of studying different incentive structures of social contexts to understand the underlying processes of conversational pragmatics, and stress the importance of considering metamemory theories of memory reporting.

Letter Spacing Does not Affect Memory and Metamemory.

Some perceptual manipulations, such as font size or bolding, can affect the estimations of future memorability (i.e., judgments of learning or JOLs). In two experiments, we studied the effect on JOLs of another perceptual manipulation: the interletter spacing. Spacing may decrease JOLs via beliefs on the effect of spacing on memory, or it may increase JOLs via feelings of processing fluency. In Experiment 1, we found that people do not hold any particular belief on the effect of spacing on memory for a list of words. In Experiment 2, we found that letter spacing did not affect JOLs. We also replicated the results that participants believe that words in large font size will be better remembered and that they rate words in large font size with higher JOLs. In sum, this research showed that not all the perceptual characteristics are used as cues to metamemory.

Is There an Early Morphological Decomposition during L2 Lexical Access? A Meta-Analysis on the Morphological Priming Effect.

A considerable body of experimental data currently exists on the representation and processing of derived words. However, no theoretical account has led to a consensus so far, due in part to inconsistencies in empirical results which show either the presence or the absence of signs of early morphological decomposition during lexical access. In this paper, we present the results of a meta-analysis that sought to examine the robustness of the masked morphological priming effect (MMP) in native and non-native speakers. This effect is indexed by faster responses to targets preceded by morphologically related primes vs. unrelated primes (e.g., fighter-FIGHT < needle-FIGHT), and is perhaps the most widespread effect used to test whether speakers of a given language are sensitive to the morphological components of words at early stages of lexical access. To this end, we selected 10 masked priming lexical decision studies (16 experiments) conducted with native and non-native speakers. Variables such as prime duration and level of L2 proficiency were considered in the analyses to assess their impact on the MMP effect. Results showed significant MMP effects, which were restricted to native speakers. No modulations were found for the prime duration. Results are interpreted in light of prevalent models of complex word processing.

Monitoring and control processes in mock witnesses in under-represented non-WEIRD samples with high or low educational level.

A popular model proposes that metamemory is based on two processes, monitoring and control. The first examines memories and evaluates their quality and the second uses that information to decide on the most appropriate course of action. Monitoring and control processes have been studied mostly with university students, which raises the question of how well do they work in groups of people from under-represented samples such as people with a low educational level. In this research, we tested the monitoring and control processes of three groups of participants from a non-WEIRD (Western, Educated, Industrialized, Rich and Democratic) country (Colombia). Two groups of adults (aged 30-55 years) living in urban or rural areas and with a low educational level and a group of Colombian university students watched a bank robbery video and answered cued recall questions. To measure monitoring ability, participants rated their confidence that they had produced the correct answer, and to measure control they indicated whether they preferred to report or withhold the response were they in a trial. Results showed that the three groups had a functional ability to monitor their memories and control their behaviour, and that university students had better memory and metamemory than the two low education groups. The results support the concept that the basic metamemory processes of monitoring and control are functional in different groups of individuals, but the differences between groups highlight the need to test the generalizability of cognitive processes and phenomena across individuals.

Do Beliefs About Font Size Affect Retrospective Metamemory Judgments in Addition to Prospective Judgments?

Beliefs about how memory works explain several effects on prospective metamemory judgments (e.g., the effect of font size on judgments of learning; JOLs). Less is known about the effect of beliefs on retrospective judgments (i.e., confidence). Here, we tested whether font size also affects confidence ratings and whether beliefs play a similar role in confidence than in JOLs. In two experiments, participants studied words in small and large size, rated JOLs, and completed a font-size test in which they indicated the font size at study and a standard old/new recognition test. The results confirmed that font size affected both JOLs and confidence ratings. The presentation of the counter-belief that memory is better for words in small font size in Experiment 2 and the analyses of confidence for participants who did not believe that large fonts improved memory suggested that the effect of font size on confidence was based on beliefs. This research shows that the debate on theory-based and experience-based factors should not be limited to prospective metamemory judgments but also encompass retrospective judgments.

The mechanisms underlying grammatical gender selection in language production: A meta-analysis of the gender congruency effect.

Grammatical gender retrieval during language production has been largely addressed through the picture-word interference (PWI) paradigm, with the aim of capturing the so-called gender congruency effect (GCE). In the PWI paradigm, participants name target pictures while ignoring superimposed written distractor nouns. The GCE shows faster responses when target and distractor nouns share the same gender than when gender differs. Yet, the locus of this effect is not clear: it might be either due to the selection of a determiner or due to the selection of a gender node at the lemma level, which may be primed or delayed by competition. Importantly, many of those who argue that the GCE is not a genuine effect of gender conclude that gender is a feature that is retrieved automatically. Such a claim is controversial since the PWI paradigm has been seen as too complex and perhaps not sensitive enough to capture small effects. Besides, for Romance languages, mixed results draw a complex picture with effects occurring mainly in the opposite direction, i.e., a gender incongruency effect (GIE). In the present study, we conducted a meta-analysis of the 18 studies that have addressed this issue. The results confirm the existence of the GCE as a determiner effect in Germanic/Slavic languages, while little support is found for the GIE in Romance languages. Nevertheless, we argue that the absence of gender effects in Germanic and Slavic languages within the PWI paradigm cannot be taken as evidence of an absence of priming/competition during gender selection and thus as evidence of an automatic selection of gender. Parametric replication of previous studies, especially those featuring bound morphemes, together with the use of other measuring techniques such as event related potentials are suggested as a way forward.

Word frequency effects on judgments of learning: More than just beliefs.

Judgments of learning (JOLs) are usually higher for high-frequency words than for low-frequency words, which has been attributed to beliefs about how word frequency affects memory. The main goal of the present study was to explore if identifying word frequency as a relevant cue is necessary for it to affect JOLs. The idea is that for one to base judgments in beliefs of how a variable affects memory, one must first consider that variable. In Experiments 1 and 2, participants studied a list of high- and low-frequency words, made immediate JOLs, and answered questions aimed at identifying the cues used to make those JOLs. The results showed that identifying word frequency as a cue was not necessary for effects on JOLs to occur, suggesting that some participants could not have used beliefs about how word frequency affects memory when making JOLs. In Experiment 3, we measured processing fluency of high- and low-frequency words through a lexical decision task. Participants identified high-frequency words quicker than low-frequency words, suggesting the former to be more fluently processed. In Experiment 4, we explored if response times in a lexical decision task mediated the effect of word frequency on JOLs. Results showed a significant mediation of 8-13%, depending on the analysis technique. We argue that theory-driven processes do not fully account for word frequency effects on JOLs.

The gender congruency effect across languages in bilinguals: A meta-analysis.

In the study of gender representation and processing in bilinguals, two contrasting perspectives exist: integrated versus autonomous (Costa, Kovacic, Franck, & Caramazza, 2003, Bilingualism: Language and Cognition, 6, 181-200). In the former, cross-linguistic interactions during the selection of grammatical gender values are expected; in the latter, they are not. To address this issue, authors have typically explored the cross-linguistic gender congruency effect (GCE; a facilitation on the naming or translation of second language [L2] nouns when their first language [L1] translations are of the same gender, in comparison to those of a different gender). However, the literature suggests that this effect is sometimes difficult to observe and might vary as a function of variables, such as the syntactic structure produced to translate or name the target (bare nouns vs. noun phrases), the phonological gender transparency of both languages (whether or not they have phonological gender cues associated with the ending letter-e.g., "-a" for feminine words and "-o" for masculine words in Romance languages), the degree of L2 proficiency, and task requirements (naming vs. translation). The aim of the present quantitative meta-analysis is to examine the robustness of the cross-linguistic GCE obtained during language production. It involves 25 experiments from 11 studies. The results support a bilingual gender-integrated view, in that they show a small but significant GCE regardless of the variables mentioned above.

Words in larger font are perceived as more important: explaining the belief that font size affects memory.

Words presented in larger font size are considered more memorable and rated with higher judgments of learning (JOLs). One explanation for this phenomenon is that people believe that font size affects memory. However, it is not clear why people hold this belief. One alternative is that font size represents importance, with larger fonts implying more relevant information. More important information is judged as more memorable and is, in fact, better remembered. In Experiments 1 and 2 we presented words in small (18 points) and extra-large font (250 points) and found higher JOLs and higher judgments of importance with extra-large fonts. A mediation analysis showed that importance accounted for 21-23% of the effect of font size on JOLs. In Experiment 3, we tested whether processing fluency was higher with the extra-large font. In a lexical decision task, participants were slower at detecting words and non-words with extra-large than small font, which is the opposite of what the processing fluency hypothesis predicts. This result shows that the font-size effect persists even in conditions in which perceived fluency should be lower. In sum, this research explained the belief that font size affects memory because words in larger fonts are considered more important.

Cognitive load eliminates the effect of perceptual information on judgments of learning with sentences.

Items presented in large font are rated with higher judgments of learning (JOLs) than those presented in small font. According to current explanations of this phenomenon in terms of processing fluency or implicit beliefs, this effect should be present no matter the type of material under study. However, we hypothesized that the linguistic cues present in sentences may prevent using font size as a cue for JOLs. Experiment 1, with short sentences, showed the standard font-size effect on JOLs, and Experiment 2, with pairs of longer sentences, showed a reduced effect. These results suggest that linguistic factors do not prevent font size from being used for JOLs. However, Experiment 3, with both short and long sentences, showed an effect of font size only for the former and not the latter condition, suggesting that the greater amount of to-be-remembered information eliminated the font-size effect. In Experiment 4, we tested a mechanism to explain this result and manipulated cognitive load using the dot-memory task. The short sentences from Experiments 1 and 3 were used, and the results replicated the font-size effect only in the low-cognitive load condition. Our results are consistent with the idea that perceptual information is used to make JOLs only with materials such as words, word pairs, or short sentences, and that the increased cognitive load required to process longer sentences prevents using font size as a cue for JOLs.

The (limited) effect of emotional arousal in the regulation of accuracy in eyewitness memory / El (limitado) efecto de la activación emocional en la regulación de la exactitud de la memoria de testigos

Witnesses encoding a crime are likely to feel negative emotions with high arousal, e.g., anxiety or fear. Negative emotions improve memory for central information and impair memory for peripheral information. In this study we explored the effects of emotional arousal and type of information in the regulation of accuracy. The regulation of accuracy allows participants to maximize accuracy, for example, by deciding on the number of alternatives in their response (the plurality option). Participants were induced with high- and low-arousal negative emotions and then shown a slideshow of a crime. Afterwards, they answered questions about central and peripheral contents of the event. Questions followed the basic plurality option procedure. First, participants selected one alternative (single answer); second, they selected three alternatives (plural answer); and, finally, they decided on reporting either the single or the plural answer. Results showed successful manipulation of arousal, and that the regulation of accuracy led to a greater increase in accuracy for peripheral than for central information, but no differences depending on the level of arousal. We also identified two factors that increased accuracy in the plurality option: the ability to discard answers with low chances of being correct and the addition of answers with higher chances of being correct. Either one, or both, can increase witness accuracy

Es muy probable que los testigos de un crimen sientan emociones negativas con un alto grado de activación, por ejemplo, ansiedad o miedo. Las emociones negativas mejoran la memoria de información central y empeoran la memoria de información periférica. En esta investigación estudiamos el efecto de la activación emocional y el tipo de información en la regulación de la exactitud. La regulación de la exactitud permite a los participantes maximizar la exactitud, por ejemplo, decidiendo cuántas alternativas quieren incluir en su respuesta (la opción de pluralidad). Se indujeron en los participantes emociones negativas con un grado de activación alto y bajo, y después se presentó una serie de diapositivas sobre un crimen. Después los participantes respondieron preguntas sobre contenidos centrales y periféricos del crimen. Las preguntas siguieron el procedimiento básico de la opción de pluralidad. Primero los participantes seleccionaron una alternativa (respuesta única), segundo seleccionaron tres alternativas (respuesta plural), y finalmente decidieron si preferían escoger la respuesta única o la plural. Los resultados mostraron que la manipulación de la activación tuvo éxito, y que hubo un mayor aumento en la exactitud con información periférica que central gracias a la regulación de la exactitud, aunque no hubo diferencias en función del nivel de activación. También se identificaron dos factores que aumentan la exactitud en la opción de pluralidad: la capacidad de descartar respuestas con bajas probabilidades de ser correctas y la adición de respuestas con mayores probabilidades de ser correctas. Cada uno de esos factores, o los dos juntos, pueden aumentar la exactitud de los testigos de un crimen

Different answers to different audiences: effects of social context on the accuracy-informativeness trade-off.

Research on conversational exchanges shows that people attempt to optimise their responses' relevance when they definitely know the correct answer (e.g., "What time is it?"). However, such certainty is often unavailable while speakers may still be under social pressure to provide an answer. We investigated how social context influences the informativeness level when answering questions under uncertainty. In three experiments, participants answered difficult general-knowledge questions placed in different social contexts (formal vs. informal). Participants generated their answers, then they were presented with a given context, and decided on the number of alternative responses they wanted to provide (single, with one alternative vs. plural, with several alternatives) and whether the answer should be reported or withheld (report option). Participants reported more answers in the informal context. In the formal context, single answers were preferred, and they were more frequently reported. We conclude that social context influences the level of informativeness in a conversation, affecting achievable accuracy. Our results also show the joint influence of the confidence and the social context on willingness to share information.

Do delayed judgements of learning reduce metamemory illusions? A meta-analysis.

Past research has shown that the perceptual characteristics of studied items (e.g., font size) lead to a metamemory illusion, and that delayed judgements of learning (JOLs) are better predictors of memory performance than immediate JOLs. Here, we tested whether delayed JOLs could reduce or eliminate the effect of perceptual characteristics on JOLs and restudy decisions. We adopted a meta-analytic approach and analysed the results of 28 experiments in which participants' studied items were presented in either large or small font. JOLs and, sometimes, restudy decisions were collected either immediately or after a delay. Finally, participants completed a memory test. The results of the meta-analyses confirmed the effect of the font size on JOLs and restudy decisions. The delayed procedures reliably reduced the effect of perceptual characteristics on JOLs, but the effect was still significant after a delay. For restudy decisions, delayed procedures only reduced numerically the effect. Surprisingly, the meta-analysis also showed a very subtle memory advantage for items presented in large font over small font, although no individual study showed a significant difference and the overall effect size was small. One plausible explanation is that after a delay, information about font size is not available for some items, causing a reduction in the effect. Moreover, our results suggest that the dissociation between memory and metamemory reported previously may not be dissociation at all, but a mistmatched effect of font size on memory and metamemory.

Effects of postwarning specificity on memory performance and confidence in the eyewitness misinformation paradigm.

The influence of postevent misinformation on memory is typically constrained by postwarnings, but little is known about the effectiveness of particular features of postwarnings, such as their specificity. Experiment 1 compared 2 levels of postwarning specificity: A general postwarning just stated the presence of misinformation, whereas a specific postwarning identified the test items for which misinformation had been presented earlier. The specific postwarning, but not the general postwarning, eliminated both the misinformation effect and its deleterious impact on memory monitoring (using a classic 2-alternative forced-choice recognition procedure). Experiment 2 ruled out an alternative interpretation of these findings and replicated this postwarning specificity pattern using a cued-recall test. We observed, in addition to the moderating influence of task representations on misinformation acceptance, 2 unexpected facilitative effects on event memory caused by misinformation. Misinformation facilitated event memory during narrative encoding if discrepancies between the event and the narrative were detected (Experiment 1) and during retrieval if a specific postwarning was combined with cued recall (Experiment 2). We interpret the facilitative effect of discrepancy detection within a recursive-remindings framework on noticing and recollecting change. (PsycINFO Database Record

Using the regulation of accuracy to study performance when the correct answer is not known.

We examined memory performance in multiple-choice questions when correct answers were not always present. How do participants answer when they are aware that the correct alternative may not be present? To answer this question we allowed participants to decide on the number of alternatives in their final answer (the plurality option), and whether they wanted to report or withhold their answer (report option). We also studied the memory benefits when both the plurality and the report options were available. In two experiments participants watched a crime and then answered questions with five alternatives. Half of the questions were presented with the correct alternative and half were not. Participants selected one alternative and rated confidence, then selected three alternatives and again rated confidence, and finally indicated whether they preferred the answer with one or with three alternatives (plurality option). Lastly, they decided whether to report or withhold the answer (report option). Results showed that participants' confidence in their selections was higher, that they chose more single answers, and that they preferred to report more often when the correct alternative was presented. We also attempted to classify a posteriori questions as either presented with or without the correct alternative from participants' selection. Classification was better than chance, and encouraging, but the forensic application of the classification technique is still limited since there was a large percentage of responses that were incorrectly classified. Our results also showed that the memory benefits of both plurality and report options overlap.

Judgments of Learning for Words in Vertical Space.

Close relationship between physical space and internal knowledge representations has received ample support in the literature. For example, location of visually perceived information in vertical space has been shown to affect different numerical judgments. In addition, physical dimensions, such as weight or font size, were shown to affect judgments of learning (JOLs, an estimation of the likelihood that an item will be remembered later, or its perceived memorability). In two experiments we tested the hypothesis that differences in positioning words in vertical space may affect their perceived memorability, i.e., JOLs. In both Experiments, the words were presented in lower or in upper screen locations. In Experiment 1, JOLs were collected in the centre of the screen following word presentation. In Experiment 2, JOLs were collected at the point of word presentation and in the same location. In both experiments participants completed a free recall test. JOLs were compared between different vertically displaced presentation locations. In general, Bayesian analyses showed evidence in support for the null effect of vertical location on JOLs. We interpret our results as indicating that the effects of physical dimensions on JOLs are mediated by subjective importance, information that vertical location alone fails to convey.

Are regulatory strategies necessary in the regulation of accuracy? The effect of direct-access answers.

Previous studies have shown that, when people asked to retrieve something from memory have the chance to regulate memory accuracy, the accuracy of their final report increases. Such regulation of accuracy can be made through one of several strategies: the report option, the grain-size option, or the plurality option. However, sometimes an answer can be directly accessed and reported without resorting to such strategies. The direct-access answers are expected to be fast, have high accuracy, and be rated with high probabilities of being correct. Thus, direct-access answers alone could explain the increase of accuracy that has been considered the outcome of regulatory strategies. If so, regulatory strategies may not be needed to explain the previous results. In two experiments, we disentangled the effects of direct-access answers and regulatory strategies in the increase of accuracy. We identified a subset of direct-access answers, and then examined the regulation of accuracy with the plurality option when they were removed. Participants answered questions with six (Exp. 1) or five (Exp. 2) alternatives. Their task was, first, to select as many alternatives as they wanted and, second, to select only two or four alternatives. The results showed that the direct-access answer affected the regulation of accuracy and made it easier. However, the results also showed that regulatory strategies, in this case the plurality option, are needed to explain why the accuracy of final report increases after successful regulation. This research highlighted the relevance of taking direct-access answers into account in the study of the regulation of accuracy.

The subjective experience of retrieval-induced forgetting.

The objective was to examine whether the lower accessibility of studied items (Rp-) that follows retrieval practice with studied items from the same category (Rp+; retrieval-induced forgetting) is correctly monitored by our cognitive system. If monitored, lower confidence for Rp- items would be expected which, in turn, would allow the control of the retrieval-induced forgetting through the report option. In Experiment 1 the standard retrieval-practice paradigm with categorised word lists was followed by a recognition test with confidence rating and the option to report or withhold the answer. Accuracy showed retrieval-induced forgetting, but there were no differences in confidence. The report option did not affect retrieval-induced forgetting. The confidence-accuracy dissociation could be due to a correct monitoring of the retrieval-induced forgetting joined with a factor that incorrectly increases confidence for Rp- items. Familiarity with the practised category was proposed as this factor and tested in Experiment 2. Despite presenting the categories more times during the retrieval-practice phase to increase their familiarity, confidence ratings were unaffected. In conclusion, this research suggests that retrieval-induced forgetting was not monitored, giving rise to a confidence-accuracy dissociation.

The influence of thematic congruency, typicality and divided attention on memory for radio advertisements.

We examined the effects of the thematic congruence between ads and the programme in which they are embedded. We also studied the typicality of the to-be-remembered information (high- and low-typicality elements), and the effect of divided attention in the memory for radio ad contents. Participants listened to four radio programmes with thematically congruent and incongruent ads embedded, and completed a true/false recognition test indicating the level of confidence in their answer. Half of the sample performed an additional task (divided attention group) while listening to the radio excerpts. In general, recognition memory was better for incongruent ads and low-typicality statements. Confidence in hits was higher in the undivided attention group, although there were no differences in performance. Our results suggest that the widespread idea of embedding ads into thematic-congruent programmes negatively affects memory for ads. In addition, low-typicality features that are usually highlighted by advertisers were better remembered than typical contents. Finally, metamemory evaluations were influenced by the inference that memory should be worse if we do several things at the same time.
