Masked Translation Priming Effects for Chinese-English-Japanese Triple Cognates in Lexical Decision Tasks.

Previous research has demonstrated cognate translation priming effects in masked priming lexical decision tasks (LDTs) even when a bilingual's two languages have different scripts. Because those effect sizes are normally larger than with noncognates, the effects have been partially attributed to the impact of prime-target phonological similarity. The present research extended that work by examining priming effects when using triple different-script cognates, i.e., /ka1 feɪ1/-coffee-コーヒー/KoRhiR/. Specifically, masked cognate priming effects were examined in six different priming directions (i.e., L1↔L2, L1↔L3, and L2↔L3) for Chinese-English-Japanese trilinguals using LDTs. Significant priming effects were observed only when the primes were from the stronger language. This asymmetric pattern suggests that the phonological similarity of cognate primes only facilitates the processing of different-script triple cognates to the extent that the processing of the prime is robust enough to make phonology available before target processing is finished.

An examination of models of reading multi-morphemic and pseudo multi-morphemic words using sandwich priming.

Rastle et al. (2004) reported that true (e.g., walker) and pseudo (e.g., corner) multi-morphemic words prime their stem words more than form controls do (e.g., brothel priming BROTH) in a masked priming lexical decision task. This data pattern has led a number of models to propose that both of the former word types are "decomposed" into their stem (e.g., walk, corn) and affix (e.g., -er) early in the reading process. The present experiments were designed to examine the models proposed to explain Rastle et al.'s effect, including models not assuming a decomposition process, using a more sensitive priming technique, sandwich priming (Lupker & Davis, 2009). Experiment 1, using the conventional masked priming procedure, replicated Rastle et al.'s results. Experiments 2 and 3, involving sandwich priming procedures, showed a clear dissociation between priming effects for true versus pseudo multi-morphemic words, results that are not easily explained by any of the current models. Nonetheless, the overall data pattern does appear to be most consistent with there being a decomposition process when reading real and pseudo multi-morphemic words, a process that involves activating (and inhibiting) lexical-level representations including a representation for the affix (e.g., -er), with the ultimate lexical decision being based on the process of resolving the pattern created by the activated representational units.

Mirror letter priming is rightward-biased but not inhibitory: Little evidence for a mirror suppression mechanism in the recognition of mirror letters.

Unlike other visual objects which are invariant to the left-right orientation, mirror letters (e.g., b and d) represent different object identities. Previous masked priming lexical decision studies have suggested that the identification of a mirror letter involves suppression of its mirror image counterpart reporting as evidence that a pseudoword prime containing the mirror letter counterpart slowed down the recognition of target word relative to a control prime containing an unrelated letter (e.g., ibea-idea > ilea-idea). Furthermore, it has been reported recently that this inhibitory mirror priming effect is sensitive to the distributional bias of left/right orientation in the Latin alphabet such that only the more dominant (frequent) right-facing mirror letter prime (e.g., b) produced interference. In the present study, we examined mirror letter priming with single letters and nonlexical letter strings with adult readers. In all experiments, relative to a visually dissimilar control letter prime, both the right-facing and left-facing mirror letter prime consistently facilitated, rather than slowed down the recognition of a target letter (e.g., b-d < w-d). Assessed against an identity prime, mirror primes showed a rightward bias, although it was small in magnitude and not always significant within an individual experiment. These results provide no support for a mirror suppression mechanism in the identification of mirror letters, and an alternative interpretation in terms of noisy perception is suggested.

Masked orthographic neighbor priming effects in Chinese two-character words

AbstractIn masked priming lexical decision tasks in alphabetic or syllabic script languages, latencies are longer when a word target is primed by a higher frequency neighbor (e.g., blue–BLUR) than when primed by an unrelated word of equivalent frequency (e.g., care–BLUR) – an “inhibitory neighbor priming effect.” In contrast, Zhou et al. (1999) demonstrated facilitatory orthographic neighbor priming for two-character Chinese words (e.g., 华丽–华贵). However, Zhou et al. did not control for relative prime-target frequency, which has been shown to be important in experiments when examining languages with other scripts. In the present Experiment 1 word neighbor primes (e.g., 容易-容貌) produced an inhibitory neighbor priming effect when the prime was higher frequency than the target, paralleling effects in other script languages. In further experiments, paralleling those in other script languages, two-character targets primed by nonword neighbors (容待-容貌) or single constituent characters matching the target in either position (容-容貌) showed significant facilitation. These results suggest that lexical activation/competition processes for two-character Chinese words are reasonably similar to those for words in alphabetic/syllabic script languages.

Investigating the Role of Response Codes in Masked Priming Lexical Decision Tasks: The Case of Repeated Presentations

The masked priming technique is considered a gold standard among experimental psychologists who specialize in the field of visual word recognition. Typically, this method entails a comparison between two or more critical conditions (e.g., the target word MOUSE being preceded by either the identity prime mouse or the unrelated prime fence). It is noteworthy that, unlike other masked priming tasks, prior experiments examining the properties of unrelated primes (e.g., their frequency as words [high or low] or their legality as nonwords [orthographically legal or illegal]) do not have an impact on the processing of the target item. However, two lexical decision studies reported faster responses to target words when the unrelated prime is a word rather than a nonword (i.e., a response congruency effect). One possible explanation for this discrepancy is a difference in methodology, as these two studies are the only ones to have used repeated presentation of stimuli, which could lead to the creation of an episodic memory trace that amplifies response congruency effects. To examine this hypothesis, we used a set of materials that did not show any congruency effect in a previous experiment with unique presentations, except that here we included repeated presentations. Results showed a response congruency effect, with participants responding faster to word targets when they were preceded by an unrelated word prime as opposed to an unrelated nonword prime. These findings suggest that the activation of response codes in masked priming is contingent upon the nature of cognitive resources required for processing the target stimuli.

Perceptual Contiguity Does Not Modulate Matched-Case Identity-Priming Effects in Lexical Decision.

In recent studies with the masked priming lexical decision task, matched-case identity-priming effects occur for nonwords but not for words (e.g., nonwords: ERTAR-ERTAR faster than ertar-ERTAR; words: ALTAR-ALTAR produces similar response times as altar-ALTAR). This dissociation is thought to result from lexical feedback influencing orthographic representations in word processing. As nonwords do not receive this feedback, bottom-up processing of prime-target integration leads to matched-case effects. However, the underlying mechanism of this effect in nonwords remains unclear. In this study, we added a color congruency manipulation across the prime and target in the matched-case identity-priming design. We aimed to determine whether the case effects originate at the early stages of prime-target perceptual integration or due to bottom-up activation of case-specific letter detectors. Results replicated the previous dissociation between words and nonwords regarding the matched-case identity effect. Additionally, we did not find any modulation of these effects by prime-target color congruency. These findings suggest that the locus of the matched-case identity effect is at an orthographic level of representation that encodes case information.

The Role of Phonological Priming in Backward Priming Effects of Chinese Four-Character Words

The backward priming effect is found in the masked lexical decision tasks deploying Chinese four-character words as targets and the backward-presented words as primes. To explore whether phonology plays a role in this backward priming effect, we conducted two experiments using the masked priming lexical decision tasks. Thirty-two and sixty-three native Chinese speakers participated in the two experiments. Experiment 1 was designed to investigate the phonological priming in backward conditions and to ensure the exclusion of phonology in Experiment 1, the primes were presented forward in Experiment 2. The results showed that no significant phonological priming effect was found whether the primes were backward-presented or forward-presented. Therefore, it can be concluded that phonological priming did not contribute to the backward priming effect in lexical decision tasks.

Just a mark: Diacritic function does not play a role in the early stages of visual word recognition.

A very common feature in most writing systems is the presence of diacritics: distinguishing marks that are added for various linguistic reasons. Most models of reading, however, have not yet captured the nature of these marks. Recent priming experiments in several languages have attempted to resolve how diacritical letters are represented in the visual word recognition system. Since the function and appearance of diacritics can change from one language to the other, it is hard to interpret the accumulated evidence. With this in mind, we conducted two masked priming lexical decision experiments in Hungarian, a transparent orthography with a wide use of diacritic vowels that allows for clear-cut manipulations. In the two experiments, we manipulated the presence or absence of the same diacritic (i.e., the acute accent) on two specific sets of letters that behave differently. In Experiment 1, the manipulation changed only the length of vowels, whereas in Experiment 2, it also changed the quality (e.g., a↝/ɒ/ vs. á↝/aː/). In both experiments, we found that primes with an omitted diacritic work just as good as the identity primes (nema→NÉMA = néma→NÉMA [mute]), whereas the addition of a diacritic comes with a cost (mése→MESE > mese→MESE [tale]). This asymmetry favors a purely perceptual account of the very early stages of word recognition, making it blind to the function of diacritics. We suggest that the linguistic functions of diacritics originate at later processing stages.

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.

Cross-script L1–L2 and L2–L1 masked translation priming and phonological priming: Evidence from unbalanced Korean–English bilinguals

Aims: Despite a history of research in translation-equivalent priming (either cognate or noncognate and phonological priming with cross-script languages), research with Korean–English bilinguals is very scarce. In this study, we report two masked-priming lexical decision tasks in both directions with Korean–English unbalanced bilinguals, investigating whether cross-language activation occurs depending on different types of cognate, noncognate, and homophone prime–target pairs, the degree of phonological similarity between prime and target, and how L2 proficiency influences each type of priming. Methodology: Two experiments were conducted using a masked translation priming paradigm with unbalanced Korean–English bilinguals: Experiment 1 in the L2–L1 direction and Experiment 2 in the L1–L2 direction. Each experiment used a total of 96 prime–target pairs of cognates, noncognates, and homophones, and 60 subjects for each experiment were asked to judge whether the items were real words or not in a lexical decision task. Data and analysis: Linear mixed-effects models were used to investigate the effects of priming in each condition, the effect of phonological similarity on cognate translation priming, and L2 proficiency. Findings/conclusions: Our results showed that both cognate translation priming and noncognate translation priming arose in the L1–L2 direction, but the phonological priming was not found. In the L2–L1 direction, on the contrary, cognate translation priming and phonological priming effects were observed, but not the noncognate translation priming. Also, the degree of phonological similarity influenced the magnitude of cognate translation priming effects in both directions with a different pattern, supporting for the phonological overlap account between different-script languages. The current study is compatible with the language nonselective activation view and suggests the shared phonological representations even between different-script languages. The results are discussed within several current bilingual lexical processing models.

Examining Language Interactivity Through Classifier Masked Primes in Chinese-English Bilinguals

One universal characteristic of human languages is grammatical agreement dependencies. In Mandarin Chinese, classifiers, or measure words, are an obligatory grammatical class used to characterize a quantified noun. The classifier is inserted in between the numeral and the noun (i.e., 一张票 yī zhāng piào, one ticket). English lacks classifiers, so their use in Chinese may lead to cross-language influence for bilinguals and second language learners. Previous research has investigated language interactivity in bilinguals, commonly through the masked priming lexical decision task (LDT), a psycholinguistic task where participants decide if a sequence of characters form a real word or not. This study investigated Chinese-English bilinguals at the University of Florida (n= 24). The experimental group consisted of Chinese-dominant bilinguals who have been in an immersive English environment for at least one semester. The control group included monolingual or dominant English bilingual speakers with another language other than Chinese. Participants completed two LDTs in a within–subjects design. Part 1 featured Chinese (L1) classifier masked primes in an overt English (L2) LDT. Part 2 featured L1 translated masked primes sharing a common classifier with target words in the overt L2 LDT. The results indicated no interaction effect between group and congruency conditions in either part (p = 0.334; p = 0.889). These findings reveal no effect of classifier primes in Chinese-English bilinguals, suggesting minimal, or the absence of cross-language influence in this context.

The processing of English prefixed and suffixed words by Chinese-English bilinguals

Aims and Objectives/Purpose/Research Questions: This study had two specific research goals. First, it investigated the relative importance of meaning and form in bilingual morphological processing of English prefixed and suffixed words. Second, it probed how target language proficiency and morphological type moderated bilingual morphological processing. Design/Methodology/Approach: This study implemented the masked morphological priming paradigm that administered three prime types (Transparent, Opaque, and Form) from two morphological types (prefix and suffix) to three Chinese-English bilingual groups (advanced, intermediate, and lower-intermediate). The critical stimuli included the Transparent (e.g., visualize-VISUAL; disagreement-DISAGREE), the Opaque (e.g., vanity-VAN; submission-MISSION), and the Form (e.g., example-EXAM; apparent-PARENT) English words. Data and Analysis: A total of 120 Chinese-English bilinguals representing three levels of distinct English competence participated in a masked priming lexical decision experiment. Direct comparisons were made using the linear mixed-effects models on bilingual groups’ priming effects from the Transparent, the Opaque, and the Form conditions of both English prefixed and suffixed words. Findings/Conclusion: The results exhibited that compared to suffixed words Chinese-English bilinguals altogether were less sensitive to the internal structure of prefixed words. The results presented that target language proficiency and morphological type moderated bilingual morphological processing, with the advanced Chinese-English bilinguals approximating previous native English speakers in processing English suffixed words. Originality: This study compared the priming effects from the Transparent, the Opaque, and the Form conditions of both English prefixed and suffixed words among three Chinese-English bilingual groups with distinct English competence. This study therefore should be the first empirical study that simultaneously evaluates the effects of target language proficiency and morphological type on bilingual morphological processing of prefixed and suffixed words. Significance/Implications: The present results indicate that target language proficiency and morphological type interact to impact bilingual morphological processing. Besides, this study provides important methodological and statistical implications for future studies.

Does online masked priming pass the test? The effects of prime exposure duration on masked identity priming

Masked priming is one of the most important paradigms in the study of visual word recognition, but it is usually thought to require a laboratory setup with a known monitor and keyboard. To test if this technique can be safely used in an online setting, we conducted two online masked priming lexical decision task experiments using PsychoPy/PsychoJS (Peirce et al., 2019). Importantly, we also tested the role of prime exposure duration (33.3 vs. 50 ms in Experiment 1 and 16.7 vs. 33.3 ms in Experiment 2), thus allowing us to examine both across conditions and within-conditions effects. We found that our online data are indeed very similar to the masked priming data previously reported in the masked priming literature. Additionally, we found a clear effect of prime duration, with the priming effect (measured in terms of response time and accuracy) being stronger at 50 ms than 33.3 ms and no priming effect at 16.7 ms prime duration. From these results, we can conclude that modern online browser-based experimental psychophysics packages (e.g., PsychoPy) can present stimuli and collect responses on standard end user devices with enough precision. These findings provide us with confidence that masked priming can be used online, thus allowing us not only to run less time-consuming experiments, but also to reach populations that are difficult to test in a laboratory.

Mirror Generalization During Early Word Recognition.

The "recycling hypothesis" posits that the word recognition system is built upon minimal modifications to the neural architecture used in object recognition. In two masked priming lexical decision studies, we examined whether "mirror generalization," a phenomenon in object recognition, occurs in word recognition. In Study 1, we found that mirrored repetition and mirrored transposed letter primes elicited significant and equivalent priming effects for mirrored targets. In Study 2, we found that mirrored and non-mirrored repetition primes both significantly facilitated processing of mirrored targets, but the priming effect was much larger for non-mirrored primes. In both studies, we also found evidence of gender differences as females showed faster response times and a larger mirror priming effect compared to males. Taken together, we conclude that mirror generalization occurs in the early orthographic stage of word recognition, but not in the later stage of lexical access, and there is a gender difference when reading mirror words.

Morphophonological activation in Chinese word recognition

Abstract The role of morphophonology during Chinese visual word recognition was investigated in three masked priming lexical decision experiments. The primes and targets were Cantonese Chinese bimorphemic words. In Chinese, most characters correspond to morphemes, but sometimes the mapping between character and morpheme is not one-to-one. Specifically, some characters are heteronymic, which had one visual form associated with multiple pronunciations and meanings (e.g., “長” is pronounced as /coeng4/ and /zoeng2/ in Cantonese, which means “long” and “senior”, respectively). In Experiment 1, facilitative priming was found when the primes and targets shared heteronymic characters of identical (e.g., “長遠-long term” /coeng4jyun5/ and “長短-length” /coeng4dyun2/), but not a different, pronunciation (e.g., “長官-senior official” /zoeng2gun1/). Sharing word-level phonology only (e.g., “場景-scene” /coeng4ging2/) had no effects. Experiment 2 replicated Experiment 1, and further indicated that the effects could not be attributed to sharing word-level meanings (e.g., “即時-immediate” /zik1si4/). Experiment 3 compared the priming effects produced by the two alternative pronunciations of the heteronymic characters. The results showed that the strength of priming was statistically comparable in the two pronunciation-congruent conditions. Together, this study provided evidence that morphophonology was activated to facilitate the ambiguity resolution of heteronymic characters. The lemma model was modified to accommodate the results.

Disentangling the Role of Deviant Letter Position on Cognate Word Processing.

The way of coding letter position has been extensively assessed during the recognition of native words, leading to the development of a new generation of models that assume more flexible letter position coding schemes compared to classical computational models such as the interactive activation (IA) model. However, determining whether similar letter position encoding mechanisms occur during the bilingual word recognition has been largely less explored despite its implications for the leading model of bilingual word recognition (multilink) as it assumes the input-coding scheme of the IA model. In this study, we aimed to examine this issue through the manipulation of the position of the deviant letter of cognate words (external and internal letters). Two experiments were conducted with Catalan–Spanish bilinguals (a masked priming lexical decision task and a two-alternative forced-choice task) and their respective monolingual controls. The results revealed a differential processing for the first letter in comparison to the other letters as well as modulations as a function of language cue, suggesting amendments to the input-coding scheme of the multilink model.

Morpho-semantic analysis of ambiguous morphemes in Chinese compound word recognition: An fMRI study

The present fMRI study examined the neural basis of processing context-supported or -unsupported interpretations of ambiguous morphemes during Chinese compound word reading in a masked priming lexical decision task. Targets were Chinese bimorphemic words that contained ambiguous morphemes. Prime words contained the same ambiguous morphemes with either the same meanings (context-supported interpretation) or different ones (context-unsupported interpretation). Lexical-level semantic sharing and unrelated control conditions were also included. Compared to the unrelated control condition, the context-supported morphemic meaning was associated with increased activity in the left SFG and bilateral MTG, and this priming effect could be dissociated from that of the lexical-level semantic-related condition. In broader brain regions, including the left SFG, bilateral MTG, left STG, right IOG, and left precuneus, the context-unsupported meaning condition showed decreased activity compared with the unrelated control condition. These findings indicate that both the context-supported and -unsupported meanings evoke significant priming effects, however, they differ from each other with different brain basis, providing new insight into the neural substrates of ambiguous morpheme processing.

The role of letter features on the consonant-bias effect: Evidence from masked priming

Recent research has shown an advantage of consonants at early stages of visual word recognition (C-bias), although the locus of this effect remains elusive. Here we examine whether the C-bias is affected by the consonant letters' features. Skilled readers performed a masked priming lexical decision task in which target words containing only either consonants without any ascending/descending features (flat words, canino[canine]) or consonants with ascending/descending features (non-flat words, palito[toothpick]) were preceded by briefly (50 ms) presented primes that could preserve the same consonants of the targets (cenune-CANINO, pelute-PALITO), the same vowels of the targets (raxizo-CANINO, fajibo-PALITO), or, as controls, unrelated (ruxuze-CANINO, fejube-PALITO) and identity primes (canino-CANINO, palito-PALITO). The case in which prime-target pairs were presented was also manipulated (lower-upper vs. upper-lower). Results showed that in both case conditions flat words were recognized faster than non-flat words. Evidence for the C-bias was observed both for flat and non-flat words in the lower-upper condition, in which a vowel inhibitory priming effect was also observed for non-flat words. In the upper-lower condition, however, the C-bias was restricted to flat words. These findings suggest that letter features play a role in the C-bias and ask for amendments in current models of visual word recognition.

Does a mark make a difference? Visual similarity effects with accented vowels.

Visual similarity effects are pervasive in masked priming (e.g., T4BLE→TABLE; obiect→OBJECT; docurnent→DOCUMENT) and can be easily explained in terms of uncertainty regarding letter identity. However, recent research failed to show visual similarity effects for primes containing accented vowels (e.g., féliz-FELIZ behaves as fáliz-FELIZ [happy in Spanish]). This null effect has been taken to suggest that accented and non-accented vowels (e.g., é and e) activate completely distinct representations. However, priming effects are reinstated for non-accented vowels (e.g., facil-FÁCIL < fecil-FÁCIL [easy in Spanish]). Here we tested the hypothesis that the lack of priming effects for primes containing accented vowels is a simple consequence of the saliency of the accent marks. To investigate this issue, we conducted a masked priming lexical decision experiment in which we minimized the saliency of the diacritical marks by using primes containing the letter i (i.e., a letter that contains itself a glyph over the letter). We manipulated prime-target visual similarity and the presence/absence of an accented vowel in the prime (e.g., obieto-OBJETO vs. obaeto-OBJETO; obíeto-OBJETO vs. obáeto-OBJETO [object in Spanish]). Results showed a sizeable visual similarity effect regardless of whether the prime was accented or not. Therefore, these findings suggest that, at least in scripts like Spanish, there is nothing special about the processing of accented vs. unaccented vowels once the saliency of the diacritical marks is reduced.
