加工水平对普通话与粤语记忆语言依赖效应的影响

通过两个实验,考察了加工水平对普通话和粤语记忆语言依赖效应的影响。实验1考察了在有意学习中的记忆语言依赖效应。结果表明,测验的语言环境对再认有重要影响。被试在粤语测验环境下对学习过的韩国语词再认反应时短,误报率却低,辨别力强,“记得”反应占优势。实验2考察了无意学习中的记忆语言依赖效应。结果表明,被试在粤语测验环境下,对评定过的韩国语词再认反应时短,误报率却高,辨别力差,但“记得”反应占优势;但在普通话测验环境下,对评定过的韩国语词再认反应时长,误报率却低,辨别力强,“知道”和“猜测”反应增加。整个研究表明,记忆的语言依赖效应在有意学习和无意学习中都存在,但有不同的趋势,表明加工水平是影响普通话和粤语记忆语言依赖效应的重要变量     

Matching words to concepts in two languages: A test of the concept mediation model of bilingual representation

A categorization paradigm was used to investigate the relations between lexical and conceptual connections in bilingual memory. Fifty-one more fluent and less fluent English-French bilinguals viewed category names (e.g.,vegetable) and then decided whether a target word (e.g.,peas) was a member of that category. The category names and target words appeared in both English and French across experimental conditions. Because category matching requires access to conceptual memory, only relatively fluent bilinguals, who are able to directly access meaning for their second language, were expected to be able to use category information across languages. The performance of lessfluent bilinguals was expected to reflect reliance on lexical-level connections between languages, requiring translation of second-language words. The results provided evidence for concept mediation by more-fluent bilinguals, because categorization latencies were independent of the language of the category name. However, the performance of less-fluent bilinguals indicated that they did not follow a simple lexical translation strategy. Instead, these subjects were faster at categorizing words in both languages when the language of the category name matched the language of the target word, suggesting that they were able to access limited conceptual information from the second language. A model of the development of concept mediation during second language acquisition is described.     

Language-dependent recall of autobiographical memories

Two studies of autobiographical memory explored the hypothesis that memories become more accessible when the linguistic environment at retrieval matches the linguistic environment at encoding. In Experiment 1, Russian-English bilinguals were asked to recall specific life experiences in response to word prompts. The results supported the hypothesis of language-dependent recall: Participants retrieved more experiences from the Russian-speaking period of their lives when interviewed in Russian and more experiences from the English-speaking period of their lives when interviewed in English. In Experiment 2, the language of the interview was varied independently from the language of the word prompts. Both variables were found to influence autobiographical recall. These findings show that language at the time of retrieval, like other forms of context, plays a significant role in determining what will be remembered.     

Cue Combinatorics in Memory Retrieval for Anaphora

Many studies have shown that memory retrieval for real‐time language processing relies on a cue‐based access mechanism, which allows the cues available at the retrieval site to directly access the target representation in memory. An open question is how different types of cues are combined at retrieval to create a single retrieval probe (“cue combinatorics”). This study addresses this question by testing whether retrieval for antecedent‐reflexive dependencies combines cues in a linear (i.e., additive) or nonlinear (i.e., multiplicative) fashion. Results from computational simulations and a reading time experiment show that target items that match all the cues of the reflexive are favored more than target items that mismatch these cues, and that different degrees of mismatches slow reading times in comparable amounts. This profile is consistent with the predictions of a nonlinear cue combination and provides evidence against models in which all cues combine in a linear fashion. A follow‐up set of simulations shows that a nonlinear rule also captures previous demonstrations of interference from nontarget items during retrieval for reflexive licensing. Taken together, these results shed new light on how different types of cues combine at the retrieval site and reveal how the method of cue combination impacts the accessibility of linguistic information in memory.     

Language‐dependent memory in bilingual learning

Spanish‐English bilinguals were taught academic‐type information about History, Biology, Chemistry and Mythology in their two languages. Upon testing, it was found that memory was more accurate and retrieval was faster when the language of retrieval and the language of encoding matched than when they did not match. For accuracy, the pattern of results was influenced by bilinguals' language proficiency, so that only balanced bilinguals whose high proficiency levels were similar in both languages showed language‐dependent recall. For reaction time, bilinguals were faster to retrieve information when the languages of retrieval and encoding matched than when they mismatched, but only for material encoded in Spanish. The influence of encoding and retrieval languages on error patterns was also examined. Together, the study's findings suggest that bilingual learning may be subject to language dependency and that experience with a language may increase the strength of linguistic cues in producing language‐dependent memory. The results are consistent with previous findings of language‐dependent memory in autobiographical narratives, carry applied implications for bilingual education, and are discussed within the theoretical framework of the relationship between language and memory.

The effect of specific test queries on source-monitoring event-related potentials

Source-monitoring decision processes were manipulated during retrieval while event-related potentials (ERPs) were recorded. Words were either seen or heard at study, and memory for modality was measured on two separate yes-no source tests. Decision processes were varied across the two tests by asking participants to respond to leading questions. One leading question asked if the items were seen at study, whereas the second question asked if the items were heard at study (cf., Marsh & Hicks, 1998). Behavioral responses indicated that leading questions altered the way in which memory was evaluated to determine the source of information. Varying the decision processes affected frontal--but not parietal ERPs--indicating that frontal ERPs reflect processing that is used to evaluate activated information. Furthermore, left and right frontal ERP activity was affected by the combination of test query and type of source supporting the hypothesis that both the right and left frontal lobes contribute to memory retrieval processes. The pattern of frontal ERP effects supports the hypothesis that activation in right frontal areas reflect basic decision processes that are used to determine source and that the left frontal lobes are recruited when more systematic processing is required by the test context (cf., Nolde, Johnson, & Raye, 1998b).     

Facilitation effects of gender-congruency in the production of Italian clitic pronouns

Psycholinguistic research has shown that the visibility of the gender-congruency effect in noun-phrase production is language-constrained. Those languages (e.g., German) for which the determiner may be selected as early as the gender information is available (“early-selection languages”) show the effect. Those languages (e.g., Italian) for which the selection of the determiner also depends on phonological information of the following noun (“late-selection languages”) do not show any effect. However, there may be gender-marked forms, different from determiners, that meet the requisites for early selection, independently from the language to which they belong. In the picture–word interference experiment reported here we asked whether the production of gender-marked Italian pronouns, by virtue of requiring only gender information for their selection, may be sensitive to the gender-congruency effect. Results showed that participants were faster when the distractor was gender-congruent vs. incongruent with respect to the picture name. This finding supports the view that the visibility of the gender-congruency effect depends on the selection properties (early vs. late) of a given condition rather than of the language itself.     

普通话和粤语记忆中的语言依赖效应

通过两个实验考察普通话和粤语环境下的记忆语言依赖效应。实验1运用自传式回忆范式,考察语言环境对情境记忆提取的影响。结果表明,在普通话和粤语环境下,普通话-粤语双言被试的回忆体现了对语言环境的依赖。当回忆时的语言环境和事件发生时的语言环境相同时,获得了更多的同类记忆。实验2通过听觉方式呈现词,考察语音和语言表达方式对再认的影响。结果表明,普通话-粤语双言被试对用粤语方言表达的词反应时间短,误报率低,辨别力强,表明语音和语言表达方式是影响普通话-粤语双言被试记忆语言依赖效应的重要因素     

Parental language mixing in bilingual families

An important question about early bilingualism that concerns both parents and researchers is the degree to which one language may interfere with another. This question rests on an implicit assumption that learning more than one language must always produce confusion and/or interference between (or among) the languages. Although many naturalistic studies have addressed this issue, no firm answers are yet available from the conflicting results obtained. Several factors appear to be responsible for the contradictory evidence, including the small numbers of subjects in each study, the large number of different language combinations of varying similarity that have been examined, and the variety of linguistic input situations (e.g., sequential bilingualism, language separation between home and school, parent/language separation), that have been observed. There is a consensus that children's language mixing can be eliminated if parents adhere strictly to the principle of one parent/one language enunciated by Grammont (Ronjat, 1913). However, this claim has not been directly examined. The primary goal of the present study is to characterize the linguistic input available to a child growing up with two languages. Analyses of the data show that a large proportion of parents, even those firmly committed to maintaining a strict separation of language by parent, model linguistically mixed utterances for their children. This finding suggests that children's early language mixing does not reflect interlinguistic confusion. Rather, it suggests that the child is formulating hypotheses about language based on the data available, i.e., that using the language of both father and mother in a single utterance is acceptable.     

Retrieval-induced forgetting: Evidence for a recall-specific mechanism

Previous work has shown that recalling information from long-term memory can impair the long-term retention of related representations—a phenomenon known as retrieval-induced forgetting (Anderson, Bjork, & Bjork, 1994). We report an experiment in which the question of whether retrieval is necessary to induce this form of impairment was examined. All the subjects studied six members from each of eight taxonomic categories (e.g.,fruit orange). In the competitive practice condition, the subjects practiced recalling three of the six members, using category-stem cues (e.g.,fruit or____). In the noncompetitive practice condition, the subjects were reexposed to these same members for the same number of repetitions but were asked to recall the category name by using the exemplar and a stem as cues (e.g.,fr____orange). Despite significant and comparable facilitation of practiced items in both conditions, only the competitive practice subjects were impaired in their ability to recall the nonpracticed members on a delayed cued-recall test. These findings argue that retrieval-induced forgetting is not caused by increased competition arising from the strengthening of practiced items, but by inhibitory processes specific to the situation of recall.     

Prospective memory: Are preparatory attentional processes necessary for a single focal cue?

The preparatory attentional and memory processes theory of prospective memory (PM) assumes that PM retrieval requires resource-demanding preparatory attentional processes, whereas the multiprocess theory assumes that retrieval can also occur spontaneously. On the basis of showing slowing on an ongoing task (i.e., task interference) —even when the PM cue was highly salient (i.e., the participant’s own name) —Smith, Hunt, McVay, and McConnell (2007) concluded that preparatory attentional processes are always necessary for PM retrieval. We argue that the presence of preparatory attentional processes cannot be used to rule out the existence of spontaneous retrieval processes, and the goal of the present research was to examine whether PM retrieval can occur in the absence of preparatory attentional processes. We varied whether we emphasized the importance of the PM task or the ongoing task, and we assessed task interference across quarters of the ongoing task. Our results showed no evidence of task interference and, hence, no evidence of preparatory attentional processes in the periods proximal to the target event, and yet participants showed high PM performance. Thus, the results suggest the existence of spontaneous retrieval processes and support the multiprocess theory.     

Immigration,language proficiency,and autobiographical memories: Lifespan distribution and second-language access

This investigation examined two controversies in the autobiographical literature: how cross-language immigration affects the distribution of autobiographical memories across the lifespan and under what circumstances language-dependent recall is observed. Both Spanish/English bilingual immigrants and English monolingual non-immigrants participated in a cue word study, with the bilingual sample taking part in a within-subject language manipulation. The expected bump in the number of memories from early life was observed for non-immigrants but not immigrants, who reported more memories for events surrounding immigration. Aspects of the methodology addressed possible reasons for past discrepant findings. Language-dependent recall was influenced by second-language proficiency. Results were interpreted as evidence that bilinguals with high second-language proficiency, in contrast to those with lower second-language proficiency, access a single conceptual store through either language. The final multi-level model predicting language-dependent recall, including second-language proficiency, age of immigration, internal language, and cue word language, explained ¾ of the between-person variance and ¹/₅ of the within-person variance. We arrive at two conclusions. First, major life transitions influence the distribution of memories. Second, concept representation across multiple languages follows a developmental model. In addition, the results underscore the importance of considering language experience in research involving memory reports.     

A reversed word length effect in coordinating the preparation and articulation of words in speaking

Speakers tend to prepare their nouns immediately before saying them, rather than preparing them further in advance. To test the limits of this last-second preparation, speakers were asked to name object pairs without pausing between names. There was not enough time to prepare the second name while articulating the first, so the speakers’ delay in starting to say the first name was based on the amount of time available to prepare the second name during speech. Before speaking, they spent more time preparing a second name (e.g., carrot) when the first name was monosyllabic (e.g., wig) rather than multisyllabic (e.g., windmill ). When additional words intervened between names, the length of the first name became less important and speech began earlier. Preparation differences were reflected in speech latencies, durations, and eye movements. The results suggest that speakers are sensitive to the length of prepared words and the time needed for preparing subsequent words. They can use this information to increase fluency while minimizing word buffering.     

A modulatory effect of male voice pitch on long-term memory in women: evidence of adaptation for mate choice?

From a functionalist perspective, human memory should be attuned to information of adaptive value for one’s survival and reproductive fitness. While evidence of sensitivity to survival-related information is growing, specific links between memory and information that could impact upon reproductive fitness have remained elusive. Here, in two experiments, we showed that memory in women is sensitive to male voice pitch, a sexually dimorphic cue important for mate choice because it not only serves as an indicator of genetic quality, but may also signal behavioural traits undesirable in a long-term partner. In Experiment 1, we report that women’s visual object memory is significantly enhanced when an object’s name is spoken during encoding in a masculinised (i.e., lower-pitch) versus feminised (i.e., higher-pitch) male voice, but that no analogous effect occurs when women listen to other women’s voices. Experiment 2 replicated this pattern of results, additionally showing that lowering and raising male voice pitch enhanced and impaired women’s memory, respectively, relative to a baseline (i.e., unmanipulated) voice condition. The modulatory effect of sexual dimorphism cues in the male voice may reveal a mate-choice adaptation within women’s memory, sculpted by evolution in response to the dilemma posed by the double-edged qualities of male masculinity.     

Do metacognitive judgments alter memory performance beyond the benefits of retrieval practice? A comment on and replication attempt of Dougherty,Scheck, Nelson,and Narens (2005)

A central question in the metacognitive literature concerns whether the act of making a metacognitive judgment alters one’s memory for the information about which the judgment was made. Dougherty, Scheck, Nelson, and Narens (2005, Memory & Cognition, 33(6), 1096–1115) attempted to address this question by having participants make either retrospective confidence judgments (RCJs; i.e., evaluations of past retrieval success), judgments of learning (JOLs; i.e., predictions of future retrieval success), or no explicit judgments. When comparing final retrieval accuracy they found that accuracy was greater for items where participants had made JOLs compared with items that received RCJs or no judgment, suggesting that simply making a JOL can improve later memory performance. The present article presents results from four separate replication attempts that fail to duplicate this finding. Combined results provide compelling evidence that making a metacognitive judgment, regardless of the type, has no impact on later memory performance above and beyond retrieval practice.     

Situation models,propositions, and the fan effect

According to theories of language comprehension, people can construct multiple levels of representation: the surface form, the propositional text base, and the situation model. In this study, I looked at how the referential nature of memory probes affects the experience of retrieval interference. All the subjects memorized sentences about objects in locations (e.g., “The potted palm is in the hotel”). When memory probes were sentences and, therefore, referential and most closely associated with the situation model level, no interference was observed during retrieval for information that could be integrated into a common situation model. In contrast, interference was observed in such cases when the memory probes were concept pairs (POTTED PALM-HOTEL) and hence not directly referential. This is interpreted to mean that nonreferential memory probes involve surface form and text base representations more than do referential sentence probes.     

Word order does not constrain phonological activation in single word production

It has recently been claimed that the canonical word order of a given language constrains phonological activation processes even in single word production (Janssen, Alario, & Caramazza, 2008). This hypothesis predicts for languages with canonical adjective–noun word order that naming an object (i.e., noun production) is facilitated if the task-irrelevant colour of the object (i.e., adjective) is phonologically similar to the object name (e.g., blue–boat as compared to red–boat). By contrast, there should be no corresponding effect in naming the colour of the object (i.e., adjective production). In an experiment with native speakers of German, however, we observed exactly the opposite pattern. Phonological congruency facilitated colour naming but had no effect on object naming. Together with extant data from other languages our results suggest that object colour naming is affected by the phonology of the object name but not vice versa, regardless of the canonical word order in the given language.     

Cued recall of specific memories in children and adults

The goal of this study was to determine some of the factors that contribute to developmental differences in using cues to retrieve specific memories. Second- and fifth-grade children and college adults were shown adjective noun-noun word stimulus events (e.g., bloody axe-sword), in which the adjectives strongly modified event meaning, and asked acquisition orienting questions that amplified (specific questions) or diluted (category questions) event specification. In addition, the stimuli were presented once only (one trial) or there was a repeated presentation with a constant or varied orienting question on the second presentation. At retrieval, orienting questions were asked of the retrieval cues that were the same as the acquisition questions, semantically related to the acquisition questions, or no questions were asked, and the retrieval cues reinstated the acquisition context (adjective noun cues) or represented the nominal type of event that was experienced (noun cues). The one-trial results showed that the children had less success than the adults using in the adjective noun retrieval cues for no questions and the related questions, relative to same questions, and also that the children used the noun cues particularly ineffectively. The event repetitions modified these patterns in predictable ways. The results suggest that type information may mediate the use of cues to retrieve specific memory tokens, and type information seems more salient in adult than in child event representations in memory.     

The artful dodger: answering the wrong question the right way

What happens when speakers try to "dodge" a question they would rather not answer by answering a different question? In 4 studies, we show that listeners can fail to detect dodges when speakers answer similar-but objectively incorrect-questions (the "artful dodge"), a detection failure that goes hand-in-hand with a failure to rate dodgers more negatively. We propose that dodges go undetected because listeners' attention is not usually directed toward a goal of dodge detection (i.e., Is this person answering the question?) but rather toward a goal of social evaluation (i.e., Do I like this person?). Listeners were not blind to all dodge attempts, however. Dodge detection increased when listeners' attention was diverted from social goals toward determining the relevance of the speaker's answers (Study 1), when speakers answered a question egregiously dissimilar to the one asked (Study 2), and when listeners' attention was directed to the question asked by keeping it visible during speakers' answers (Study 4). We also examined the interpersonal consequences of dodge attempts: When listeners were guided to detect dodges, they rated speakers more negatively (Study 2), and listeners rated speakers who answered a similar question in a fluent manner more positively than speakers who answered the actual question but disfluently (Study 3). These results add to the literatures on both Gricean conversational norms and goal-directed attention. We discuss the practical implications of our findings in the contexts of interpersonal communication and public debates.     

No Benefit of Eye-Closure Rehearsal in a Unimodal Recognition Memory Test for Word Items

Recent studies have suggested that closing the eyes helps memory retrieval in recall tests for audiovisual clips that contain multimodal information. In two experiments, we examined whether eye-closure improves recognition memory performance for word lists presented unimodally (i.e., visually or aurally). In the encoding phase, participants saw or heard a list of unrelated, meaningful word items. After a fixed retention interval of 1 week (Experiment 1, n = 110) and 5 min (Experiment 2, n = 44), the participants were asked to mentally rehearse the items with their eyes open or closed, and then they performed a recognition test. The results revealed no effect of eye-closure rehearsal on recognition performance. We discuss the possible reasons why no eye-closure benefit was found in recognition memory tests for unrelated word items.
