Asymmetries in the Stem and Suffix Masked Priming Response in a Large-scale Online Study

Models of visual word processing incorporate morphological decomposition as a step in the recognition process, but they vary as to when this step happens, and what kind of information is used in it. In particular, the affix stripping model proposes that words are accessed through their stems, after affixes are automatically stripped off. This dichotomy between stems and affixes seems to be mirrored in masked priming. Masked stem priming is quite robust and comparable to masked repetition priming, whereas masked affix priming is often null, or very small. However, the literature on masked affix priming is much smaller than the one on masked stem priming. This study investigates the stem vs suffix asymmetry in masked priming by running an online experiment with a large sample size (N=161) to ensure higher statistical power. For comparison and validation, the same experiment was also conducted in a standard lab setting. In addition, we ran a follow-up experiment with two additional suffix priming conditions with an even larger sample size (N=400) to assess the influence of orthographic and strategic confounds. The three experiments show significant stem priming, but null or very small suffix priming, thus supporting the asymmetry between stem activation and affix stripping.

Asymetric Event-Related Potential Priming Effects Between English Letters and American Sign Language Fingerspelling Fonts.

Letter recognition plays an important role in reading and follows different phases of processing, from early visual feature detection to the access of abstract letter representations. Deaf ASL-English bilinguals experience orthography in two forms: English letters and fingerspelling. However, the neurobiological nature of fingerspelling representations, and the relationship between the two orthographies, remains unexplored. We examined the temporal dynamics of single English letter and ASL fingerspelling font processing in an unmasked priming paradigm with centrally presented targets for 200 ms preceded by 100 ms primes. Event-related brain potentials were recorded while participants performed a probe detection task. Experiment 1 examined English letter-to-letter priming in deaf signers and hearing non-signers. We found that English letter recognition is similar for deaf and hearing readers, extending previous findings with hearing readers to unmasked presentations. Experiment 2 examined priming effects between English letters and ASL fingerspelling fonts in deaf signers only. We found that fingerspelling fonts primed both fingerspelling fonts and English letters, but English letters did not prime fingerspelling fonts, indicating a priming asymmetry between letters and fingerspelling fonts. We also found an N400-like priming effect when the primes were fingerspelling fonts which might reflect strategic access to the lexical names of letters. The studies suggest that deaf ASL-English bilinguals process English letters and ASL fingerspelling differently and that the two systems may have distinct neural representations. However, the fact that fingerspelling fonts can prime English letters suggests that the two orthographies may share abstract representations to some extent.

Priming asymmetry persists in German-English-French trilinguals: the sense model modified for the trilingual mental lexicon

ABSTRACT The present study examined within – and cross-language priming patterns among German-English-French trilinguals in order to explore the lexico-semantic representation of L3 in relation to L1 and L2. The trilinguals participated in three lexical decision tasks within the masked translation priming paradigm. The results showed significant within-language repetition priming effects in all three languages, significant translation priming effects for L2-L1, L1-L3, and L2-L3, but no significant priming for L1-L2, L3-L1 or L3-L2. Our findings demonstrate that translation priming asymmetry persists in trilinguals and that the weakest L3 is integrated into both L1 and L2 conceptually (i.e. three languages have a commonly shared conceptual representation). In addition, our results showed a language dominance shift over lexical development between L1 and L2. We argue for a modified Sense Model as the best fit to explain the cognitive architecture of the trilingual lexicon.

Some neighbors are more interfering: Asymmetric priming by stroke neighbors in Chinese character recognition

Chinese is a visually complex logographic script that consists of square-shaped characters, with each character composed of strokes. Previous masked priming studies using single-character Chinese stroke neighbors (i.e., visually similar characters differing in only one or two strokes, e.g., 大/犬) have shown facilitatory or inhibitory priming effects. We tested whether the mixed pattern of stroke neighbor priming might be an instance of asymmetry in priming that has been observed previously with Japanese kana and Latin alphabets. Specifically, a prime lacking a stroke (or line segment) that is present in the target speeds up the recognition of its stroke neighbor almost as much as the identity prime (e.g., 刀-刃 = 刃-刃), but not the converse (e.g., 刃-刀 >> 刀-刀). Two experiments, one using a character match task and the second using lexical decision, showed a robust asymmetry in priming by stroke neighbors. The results suggest that the early letter identification process is similar across script types, as anticipated by the Noisy Channel model, which regards the first stage of visual word recognition as a language-universal perceptual process.

Leading Us Unto Temptation? No Evidence for an Asymmetry in Automatic Associations Between Goals and Temptations

The asymmetry hypothesis of counteractive control theory suggests that—at least for successful self-regulators—exposure to temptations facilitates the accessibility of goal-related cognitive constructs, whereas exposure to goals inhibits the accessibility of temptation-related cognitive constructs. Using a lexical decision task, Fishbach et al., 2003 (Study 3) found that this asymmetry existed even at an automatic level of processing. In this attempted replication, 221 students completed a lexical decision task that included goal-related and temptation-related stimuli words preceded by either a goal-related prime, a temptation-related prime, or an irrelevant prime. Unlike the original study, we found only significant priming effects, where temptation-primes facilitated the recognition of goal-related words and goal-primes likewise facilitated the recognition of temptation-related words. We did not replicate the previously reported asymmetry. Additionally, we found no significant moderation of the hypothesized priming asymmetry by any of the traits of self-regulatory success, construal level, temptation strength, or self-control, again failing to replicate prior findings. The same priming patterns were found among participants who completed the study in-lab and those who completed the study online. This replication study suggests that the cognitive associations between goals and temptations are relatively symmetric and faciliatory, at least during the initial, automatic level of cognitive processing.

Letter identity and visual similarity in the processing of diacritic letters.

Are letters with a diacritic (e.g., â) recognized as a variant of the base letter (e.g., a), or as a separate letter identity? Two recent masked priming studies, one in French and one in Spanish, investigated this question, concluding that this depends on the language-specific linguistic function served by the diacritic. Experiment 1 tested this linguistic function hypothesis using Japanese kana, in which diacritics signal consonant voicing, and like French and unlike Spanish, provide lexical contrast. Contrary to the hypothesis, Japanese kana yielded the pattern of diacritic priming like Spanish. Specifically, for a target kana with a diacritic (e.g., ガ, /ga/), the kana prime without the diacritic (e.g., カ, /ka/) facilitated recognition almost as much as the identity prime (e.g., ガ-ガ = カ-ガ), whereas for a target kana without a diacritic, the kana prime with the diacritic produced less facilitation than the identity prime (e.g., カ-カ < ガ-カ). We suggest that the pattern of diacritic priming has little to do with linguistic function, and instead it stems from a general property of visual object recognition. Experiment 2 tested this hypothesis using visually similar letters of the Latin alphabet that differ in the presence/absence of a visual feature (e.g., O and Q). The same asymmetry in priming was observed. These findings are consistent with the noisy channel model of letter/word recognition (Norris & Kinoshita, Psychological Review, 119, 517-545, 2012a).

Asymmetrical Priming Effects: An Exploration of Trilingual German-English-French Lexico-Semantic Memory.

The growing number of multilingual speakers poses an interesting question as to the way in which three or more languages are represented in the memory of a language user. The Revised Hierarchical Model (Kroll and Stewart in J Mem Lang 33: 149-174, 1994) or the Sense Model (Finkbeiner et al. in J Mem Lang 51(1), 1-22, 2004) skillfully capture the prediction regarding two languages, with the lexical level being separate and the conceptual one being unified or distributed to a varying degree. In this set of experiments, we employed primed animacy decision tasks to address the lexico-semantic representation of trilingual German-English-French speakers. The comparison of reaction times has revealed priming effects from L1 to L2 and from L2 to L1, both with prime duration of 100 and 50ms; a priming asymmetry effect between the L2 and L3 language directions; and no interaction between L1 and L3. The aggregated findings point to a hybrid representation, with both compound and coordinate representations being possible.

The effects of language immersion on the bilingual lexicon

Abstract Previous studies have consistently found an asymmetry where priming in the L1-L2 direction is stronger than that in the L2-L1 direction. However, some studies showed that an L2 immersion environment could attenuate bilingual speakers’ access to the L1 and result in a ‘bilingual disadvantage’. This study investigated how language immersion modulates the priming effects of late adult bilingual speakers. We compared late Chinese-English bilingual speakers with high L2 (English) proficiency in an L1 environment and those in an L2 immersion environment. Both semantic and translation priming in same-language and cross-language conditions were investigated. The results showed no ‘bilingual disadvantage’ of the immersed participants. The priming asymmetry was weakened for the immersed participants who were more comparable in their reaction time to different language conditions. Both semantic and translation priming were found in L1-L2 and L2-L1 directions, suggesting that both types of priming are similar in nature in the bilingual lexicon.

Cross-language priming as a means of investigating bilingual conceptual representations

Abstract Cross language priming in the visual modality is a well-established paradigm that offers insights into the representation of the bilingual mental lexicon; however, here we employ a novel form of priming, (i.e., an animacy decision task), to test previous outcomes. In addition, this study is the first to carry out an auditory priming task with bilingual Chinese-English speakers. Thus, we report on two experiments in which the participants decided whether visually (Experiment 1) or auditorily (Experiment 2) presented stimuli were exemplars of living entities or non-living things. The tasks allowed for addressing the priming effect, the priming asymmetry effect, and in turn allowed for testing the Revised Hierarchical Model (Kroll &amp; Stewart, 1994). Priming effects, where the related targets were responded to more rapidly compared to unrelated targets, were observed in both modalities in the L1 to L2 condition; however, no priming effects were found from L2 to L1. The findings obtained in this study support the use of primed animacy decision tasks in either modality as a valid tool for investigating bilingual lexical memory. Also, the observed priming effects allow for retaining the RHM in its original form.

On the nature of consonant/vowel differences in letter position coding: Evidence from developing and adult readers.

In skilled adult readers, transposed-letter effects (jugde-JUDGE) are greater for consonant than for vowel transpositions. These differences are often attributed to phonological rather than orthographic processing. To examine this issue, we employed a scenario in which phonological involvement varies as a function of reading experience: A masked priming lexical decision task with 50-ms primes in adult and developing readers. Indeed, masked phonological priming at this prime duration has been consistently reported in adults, but not in developing readers (Davis, Castles, & Iakovidis, 1998). Thus, if consonant/vowel asymmetries in letter position coding with adults are due to phonological influences, transposed-letter priming should occur for both consonant and vowel transpositions in developing readers. Results with adults (Experiment 1) replicated the usual consonant/vowel asymmetry in transposed-letter priming. In contrast, no signs of an asymmetry were found with developing readers (Experiments 2-3). However, Experiments 1-3 did not directly test the existence of phonological involvement. To study this question, Experiment 4 manipulated the phonological prime-target relationship in developing readers. As expected, we found no signs of masked phonological priming. Thus, the present data favour an interpretation of the consonant/vowel dissociation in letter position coding as due to phonological rather than orthographic processing.

Masked translation priming asymmetry in Chinese-English bilinguals: making sense of the Sense Model.

Masked translation priming asymmetry is the robust finding that priming from a bilingual's first language (L1) to their second language (L2) is stronger than priming from L2 to L1. This asymmetry has been claimed to be task dependent. The Sense Model proposed by Finkbeiner, Forster, Nicol, and Nakamura (2004) claims that the asymmetry is reduced in semantic categorization relative to lexical decision due to a category filtering mechanism that limits the features considered in categorization decisions to dominant, category-relevant features. This paper reports two pairs of semantic categorization and lexical decision tasks designed to test the Sense Model's predictions. The experiments replicated the finding of Finkbeiner et al. that L2-L1 priming is somewhat stronger in semantic categorization than lexical decision, selectively for exemplars of the category. However, the direct comparison of L2-L1 and L1-L2 translation priming across tasks failed to confirm the Sense Model's central prediction that translation priming asymmetry is significantly reduced in semantic categorization. The data therefore fail to support the category filtering account of translation priming asymmetry. Rather, they suggest that pre-activation of conceptual features of the target category provides feedback to lexical forms that compensates for the weak connections between the lexical and conceptual representations of L2 words.

Is translation priming asymmetry due to partial awareness of the prime?

A 50ms prime duration is often adopted in both L1-L2 and L2-L1 directions in the cross-language priming paradigm. It is unknown how aware bilinguals are of the briefly presented primes of different scripts; and whether the degree of awareness of L1 and L2 primes is at a similar level. Kouider and Dupoux's (2004) proposal of partial awareness suggests that 50ms English primes were sufficient to make a semantic interpretation. It is unclear whether this is the case when processing one's L2 or a different script. Experiment 1 was designed to measure the comparable prime durations for semantic interpretation of Chinese primes vs. English primes. Experiment 2 tested whether partial awareness of primes would cause priming asymmetry. Our findings demonstrate that a 50ms prime duration gave rise to different degrees of semantic activation in different scripts and L1/L2. However, increasing prime duration on L2 primes did not produce L2-L1 priming.

Dynamic Tuning of Electrical and Chemical Synaptic Transmission in a Network of Motion Coding Retinal Neurons

Recently, we demonstrated that gap junction coupling in the population of superior coding ON-OFF directionally selective ganglion cells (DSGCs) genetically labeled in the Hb9::eGFP mouse retina allows the passage of lateral anticipatory signals that help track moving stimuli. Here, we examine the properties of gap junctions in the DSGC network, and address how interactions between electrical and chemical synapses and intrinsic membrane properties contribute to the dynamic tuning of lateral anticipatory signals. When DSGC subtypes coding all four cardinal directions were individually loaded with the gap junction-permeable tracer Neurobiotin, only superior coding DSGCs exhibited homologous coupling. Consistent with these anatomical findings, gap junction-dependent feedback spikelets were only observed in Hb9(+) DSGCs. Recordings from pairs of neighboring Hb9(+) DSGCs revealed that coupling was reciprocal, non-inactivating, and relatively weak, and provided a substrate for an extensive subthreshold excitatory receptive field around each cell. This subthreshold activity appeared to boost coincident light-driven chemical synaptic responses. However, during responses to moving stimuli, gap junction-mediated boosting appeared to be dynamically modulated such that upstream DSGCs primed downstream cells, but not vice versa, giving rise to highly skewed responses in individual cells. We show that the asymmetry in priming arises from a combination of spatially offset GABAergic inhibition and activity-dependent changes in intrinsic membrane properties of DSGCs. Thus, dynamic interactions between electrical and chemical synapses and intrinsic membrane properties allow the network of DSGCs to propagate anticipatory responses most effectively along their preferred direction without leading to runaway excitation.

The consequences of language proficiency and difficulty of lexical access for translation performance and priming.

Repetition priming was used to assess how proficiency and the ease or difficulty of lexical access influence bilingual translation. Two experiments, conducted at different universities with different Spanish-English bilingual populations and materials, showed repetition priming in word translation for same-direction and different-direction repetitions. Experiment 1, conducted in an English-dominant environment, revealed an effect of translation direction but not of direction match, whereas Experiment 2, conducted in a more balanced bilingual environment, showed an effect of direction match but not of translation direction. A combined analysis on the items common to both studies revealed that bilingual proficiency was negatively associated with response time (RT), priming, and the degree of translation asymmetry in RTs and priming. An item analysis showed that item difficulty was positively associated with RTs, priming, and the benefit of same-direction over different-direction repetition. Thus, although both participant accuracy and item accuracy are indices of learning, they have distinct effects on translation RTs and on the learning that is captured by the repetition-priming paradigm.

Cross-Language Translation Priming Asymmetry with Chinese-English Bilinguals: A Test of the Sense Model

The present study aimed to test the Sense Model of cross-linguistic masked translation priming asymmetry, proposed by Finkbeiner et al. (J Mem Lang 51:1-22, 2004), by manipulating the number of senses that bilingual participants associated with words from both languages. Three lexical decision experiments were conducted with Chinese-English bilinguals. In Experiment 1, polysemous L2 words and their L1 Chinese single-sense translation equivalents were selected as primes and targets. In Experiment 2, single-sense L1 words and their L2 translation equivalents with polysemous senses severed as primes and targets. We found translation priming effects in the L1-L2 direction, but not in the L2-L1 direction. In Experiment 3, presentation time of the L2 priming stimulus was prolonged, and significant translation priming effects were observed in the L2-L1 direction. These findings suggest that the Sense Model does not adequately explain cross-language translation priming asymmetry. The sense numbers of primes and targets, as well as the activation proportion of these senses between them, were possibly not the primary reason for cross-language translation priming asymmetry. The revised hierarchical model (Kroll and Stewart in J Mem Lang 33:149-174, 1994) and the BIA+ model (Dijkstra and van Heuven in Bilingualism Lang Cognit 5:175-197, 2002) better explain the cross-language translation priming asymmetry we found.

Language dominance in translation priming: Evidence from balanced and unbalanced Chinese–English bilinguals

It is well established in the masked translation priming literature that the priming effect is sensitive to language direction with noncognates-namely, the priming effect is consistently observed from first language (L1) to second language (L2), but not always from L2 to L1. Several recent reports demonstrated both L1-L2 and L2-L1 priming and attributed the restoration of L2-L1 priming to high proficiency in L2. Here, the current study tested two groups of highly proficient Chinese-English bilinguals, with one group more dominant in English and the other more balanced in both languages. The L2-L1 priming effect was only observed with the balanced bilinguals, but not the English-dominant ones. Based on these results, I argue that the language proficiency account is not sufficient to explain the priming asymmetry and that the relative bilingual balance is a more accurate account. Theoretically, the cross-language balance is determined by the representational difference between L1 and L2 at the semantic level. I discuss the results in relation to various bilingual models, in particular, the sense model and the distributional representational model (DRM), which capture the semantic representations of bilinguals.

The Roles of Semantic Sense and Form-Meaning Connection in Translation Priming

This study examines semantic sense and form-meaning connection across the bilingual’s languages as factors behind translation priming asymmetry, which refers to semantic priming between translation equivalents with L1 (first language) primes and L2 (second language) targets, but the lack of it in the reverse direction. In Experiment 1, many-sense L2 words did prime their L1 translations having fewer senses in a lexical decision task, contradicting the usual lack of L2-to-L1 priming. Results of Experiment 2 showed that few-sense L2 items did not prime their many-sense translations, but priming occurred in the reverse direction. In Experiment 3, only single-sense items were used, and priming occurred in the L1-to-L2 but not the L2-to-L1 direction, replicating the usual asymmetry. In Experiment 4, priming occurred in the L1-few-L2-many direction, indicating that form-meaning connection strength plays a role over the semantic sense ratio in this situation. Hence, both the relative number of item senses and item form-meaning connection strength (L1 > L2 by default, with number of senses controlled in Experiment 3) contribute to translation priming asymmetry.

Rapid communication: Perceptual strength is different from sensorimotor strength: Evidence from the centre–periphery asymmetry in masked priming

Near-threshold prime stimuli can facilitate or hinder responses to target stimuli, creating either a positive compatibility effect (PCE) or a negative compatibility effect (NCE). An asymmetry has been reported between primes presented in near periphery, which produced a PCE, and foveal primes, which produced an NCE under comparable conditions. This asymmetry has been attributed to the difference in retinal sensitivity, but it remains unclear whether this means that equating discrimination performance for primes in fovea and periphery, in order to account for differences in perceptual sensitivity, would make the priming effects the same. Wider work indicates that perceptual ability can dissociate from visuomotor effects, predicting that equating perceptual ability for fovea and periphery would not equate priming. We tested these opposite possibilities by matching discrimination performance for masked Gabor patches in fovea and near periphery (6°) and using these as primes in a masked priming paradigm expected to elicit NCEs. We found the asymmetry remained: NCE for fovea and PCE for periphery. We replicated this with both blocked and randomized procedures to check for attentional effects. We conclude that equating perceptual strength (discriminability) of stimuli does not equate their sensorimotor impact due to differences in the relative importance of different visual pathways and differing temporal dynamics in perceptual and sensorimotor processes.

The relative position priming effect depends on whether letters are vowels or consonants.

The relative position priming effect is a type of subset priming in which target word recognition is facilitated as a consequence of priming the word with some of its letters, maintaining their relative position (e.g., csn as a prime for casino). Five experiments were conducted to test whether vowel-only and consonant-only subset primes contribute equally to this effect. Experiment 1 revealed that this subset priming effect emerged when primes were composed exclusively of consonants, compared with vowel-only primes (csn-casino vs. aia-animal). Experiment 2 tested the impact of letter frequency in this asymmetry. Subset priming effects were obtained for both high- and low-frequency consonants but not for vowels, which rules out a letter frequency explanation. Experiment 3 tested the role of phonology and its contribution to the priming effects observed, by decreasing the prime duration. The results showed virtually the same effects as in the previous experiments. Finally, Experiments 4 and 5 explored the influence of repeated letters in the primes on the magnitude of the priming effects obtained for consonant and vowel subset primes (iuo-dibujo and aea-madera vs. mgn-imagen and rtr-frutero). Again, the results confirmed the priming asymmetry. We propose that a functional distinction between consonants and vowels, mainly based on the lexical constraints imposed by each of these types of letters, might provide an explanation for the whole set of results.

Masked translation priming effects with low proficient bilinguals

Non-cognate masked translation priming lexical decision studies with unbalanced bilinguals suggest that masked translation priming effects are asymmetric as a function of the translation direction (significant effects only in the dominant [L1] to nondominant [L2] language translation direction). However, in contrast to the predictions of most current accounts of masked translation priming effects, bidirectional effects have recently been reported with a group of low proficient bilinguals Duyck & Warlop 2009 (Experimental Psychology 56:173-179). In a series of masked translation priming lexical decision experiments we examined whether the same pattern of effects would emerge with late and low proficient Greek (L1)-Spanish (L2) bilinguals. Contrary to the results obtained by Duyck and Warlop, and in line with the results found in most studies in the masked priming literature, significant translation priming effects emerged only when the bilinguals performed the task with L1 primes and L2 targets. The existence of the masked translation priming asymmetry with low proficient bilinguals suggests that cross-linguistic automatic lexico-semantic links may be established very early in the process of L2 acquisition. These findings could help to define models of bilingualism that consider L2 proficiency level to be a determining factor.
