Malay Lexicon Project 3: The impact of orthographic-semantic consistency on lexical decision latencies

Theories of word processing propose that readers are sensitive to statistical co-occurrences between spelling and meaning. Orthographic-semantic consistency (OSC) measures provide a continuous estimate of the statistical regularities between spelling and meaning. Here we examined Malay, an Austronesian language that is agglutinative. In Malay, stems are often repeated in other words that share a related meaning (e.g., sunyi/quiet; ke-sunyi-an/silence; makan/eat; makan-an/foods). The first goal was to expand an existing large Malay database by computing OSC estimates for 2,287 monomorphemic words. The second goal was to explore the impact of root family size and OSC on lexical decision latencies for monomorphemic words. Decision latencies were collected for 1,280 Malay words of various morphological structures. Of these, data from 1,000 monomorphemic words were analysed in a series of generalised additive mixed models (GAMMs). Root family size and OSC were significant predictors of decision latencies, particularly for lower frequency words. We found a facilitative effect of root family size and OSC. Furthermore, we observed an interaction between root family size and OSC in that an effect of OSC was only apparent in words with larger root families. This interaction has not yet been explored in English but has the potential to be a new benchmark effect to test distributional models of word processing.

Cross-language semantic parafoveal preview benefits in bilinguals

The aim of this project was to identify factors contributing to cross-language semantic preview benefits. In Experiment 1, Russian-English bilinguals read English sentences with Russian words presented as parafoveal previews. The gaze-contingent boundary paradigm was used to present sentences. Critical previews were cognate translations of the target word (CTAPT-START), noncognate translations (CPOK-TERM), or interlingual homograph translations (MOPE-SEA). A semantic preview benefit (i.e., shorter fixation durations for related than unrelated previews) was observed for cognate and interlingual homograph translations, but not for noncognate translations. In Experiment 2, English-French bilinguals read English sentences with French words used as parafoveal previews. Critical previews were interlingual homograph translations of the target word (PAIN-BREAD) or interlingual homograph translations with a diacritic added (PÁIN-BREAD). A robust semantic preview benefit was found only for interlingual homographs without diacritics, although both preview types produced a semantic preview benefit in the total fixation duration. Our findings suggest that semantically related previews need to have substantial orthographic overlap with words in the target language to produce cross-language semantic preview benefits in early eye fixation measures. In terms of the Bilingual Interactive Activation+ model, the preview word may need to activate the language node for the target language before its meaning is integrated with that of the target word.

The effect of speaker age on the perception of ironic insults

We investigated a cue that readers may use in determining whether a remark such as "You are so helpful!" is intended as a compliment or as an ironic insult. The cue was the age of the speaker. Remarks were preceded by a sentence that either invited a literal or ironic interpretation of the remark. Data were collected on the familiarity of the remark as an ironic statement, and the incongruity of the remark with the prior context. In Experiment 1, participants were asked to rate the intent of the speaker as to how ironic, mocking, polite, and funny they intended their remark to be. In Experiment 2, participants read the scenarios as their eye movements were tracked. The results showed that age of the speaker had an impact on first pass reading times when statements were not familiar as ironic statements. Our younger adult participants did not appear to immediately activate a nonliteral interpretation of an ambiguous remark made by an older adult unless they had evidence from past experience that the remark is often used as an insult. However, ratings of the ironic intent of the statements were unaffected by speaker age; the age of the speaker affects the ease of interpretation but not the final outcome. The results are consistent with constraint-based theories of sentence comprehension. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

Figuring Out How Verb-Particle Constructions Are Understood During L1 and L2 Reading

The aim of this paper was to investigate first-language (L1) and second-language (L2) reading of verb particle constructions (VPCs) among English-French bilingual adults. VPCs, or phrasal verbs, are highly common collocations of a verb paired with a particle, such as eat up or chew out, that often convey a figurative meaning. VPCs vary in form (eat up the candy vs. eat the candy up) and in other factors, such as the semantic contribution of the constituent words to the overall meaning (semantic transparency) and frequency. Much like classic forms of idioms, VPCs are difficult for L2 users. Here, we present two experiments that use eye-tracking to discover factors that influence the ease with which VPCs are processed by bilingual readers. In Experiment 1, we compared L1 reading of adjacent vs. split VPCs, and then explored whether the general pattern was driven by item-level factors. L1 readers did not generally find adjacent VPCs (eat up the candy) easier to process than split VPCs (eat the candy up); however, VPCs low in co-occurrence strength (i.e., low semantic transparency) and high in frequency were easiest to process in the adjacent form during first pass reading. In Experiment 2, we compared L2 reading of adjacent vs. split VPCs, and then explored whether the general pattern varied with item-level or participant-level factors. L2 readers generally allotted more second pass reading time to split vs. adjacent forms, and there was some evidence that this pattern was greater for L2 English readers who had less English experience. In contrast with L1 reading, there was no influence of item differences on L2 reading behavior. These data suggest that L1 readers may have lexicalized VPC representations that are directly retrieved during comprehension, whereas L2 readers are more likely to compositionally process VPCs given their more general preference for adjacent particles, as demonstrated by longer second pass reading time for all split items.

Effects of lexical ambiguity on perception: A test of the label feedback hypothesis using a visual oddball paradigm

We used a visual oddball paradigm to investigate whether a shared verbal label makes two objects belonging to different conceptual categories less perceptually distinct. In Experiment 1, the critical images shared a label as well as some perceptual features (orange, referring to the color and the fruit), and in Experiment 2, the critical images shared a label but no perceptual features (bat, referring to the animal and the sports equipment). In both experiments comparison images were similar to each of the critical images but they did not share a label. A reduced deviant-related negativity (DRN) was observed for critical images compared with comparison images in both experiments, suggesting that the critical image pairs were perceived as less distinct than comparison pairs. These results extend previous research using the visual oddball paradigm that has shown that images from the same conceptual category are perceived as more distinct when they have different labels, and provide further support for the label-feedback hypothesis (Lupyan, 2012) in which language is assumed to modulate perception online.

Reading homophone puns: Evidence from eye tracking

We investigated how readers make sense of homophone puns (e.g., The butcher was very glad we could meat up) by tracking their eye movements as they read. Comparison sentences included homophone-error sentences in which the presented homophone was also not correct (e.g., The lawyer was very glad we could meat up) and sentences in which the homophone was correct for the context (e.g., The butcher was very glad to chop meat up for the stew). An effect of the frequency of the unpresented homophone mate (e.g., meet) was found on first-pass reading times for homophones, indicating that participants activated the meaning of the homophone mate through shared phonology. First-fixation and gaze durations on the homophones were longer in puns than in correct-context sentences, indicating that participants immediately noticed that the homophone was incongruous with the adjacent context (e.g., glad we could meat) in puns, but total reading times did not differ, suggesting that the incongruity was quickly resolved. Immediate reading times on homophone in puns and homophone-error sentences did not differ, but total reading times did, suggesting that the impact of the critical context word (e.g., butcher) is delayed. Further analyses examined the resolution process in more detail. Ratings of the funniness of the puns were most strongly related to the strength of the association between the homophone and the critical context word (e.g., butcher). (PsycINFO Database Record

The role of lexical expertise in reading homophones

In Experiment 1, university students classified on lexical expertise on the basis of spelling plus nonword pronunciation accuracy made lexical decisions to homophones and control words. Homophones were accepted as words more slowly than control words, but lexical experts showed a smaller homophone cost than the less skilled group. In Experiment 2, similarly classified groups showed a large difference in their ability to detect homophones, with the low-expertise group showing a yes bias to high-frequency words, and having difficulty detecting homophones when mate-frequency was low. The results suggest superior use of orthography in the lexical experts and more reliance on semantic information in nonexperts, and support the importance of facility with orthography-phonology mappings in lexical expertise.

The effect of semantic transparency on the processing of morphologically derived words: Evidence from decision latencies and event-related potentials

Decomposition theories of morphological processing in visual word recognition posit an early morpho-orthographic parser that is blind to semantic information, whereas parallel distributed processing (PDP) theories assume that the transparency of orthographic-semantic relationships influences processing from the beginning. To test these alternatives, the performance of participants on transparent (foolish), quasi-transparent (bookish), opaque (vanish), and orthographic control words (bucket) was examined in a series of 5 experiments. In Experiments 1-3 variants of a masked priming lexical-decision task were used; Experiment 4 used a masked priming semantic decision task, and Experiment 5 used a single-word (nonpriming) semantic decision task with a color-boundary manipulation. In addition to the behavioral data, event-related potential (ERP) data were collected in Experiments 1, 2, 4, and 5. Across all experiments, we observed a graded effect of semantic transparency in behavioral and ERP data, with the largest effect for semantically transparent words, the next largest for quasi-transparent words, and the smallest for opaque words. The results are discussed in terms of decomposition versus PDP approaches to morphological processing. (PsycINFO Database Record

Cross-script orthographic and phonological preview benefits

The present experiment examined the use of parafoveally presented first-language (L1) orthographic and phonological codes during reading of second-language (L2) sentences in proficient Russian-English bilinguals. Participants read English sentences containing a Russian preview word that was replaced by the English target word when the participant's eyes crossed an invisible boundary located before the preview word. The use of English and Russian allowed us to manipulate orthographic and phonological preview effects independently of one another. The Russian preview words overlapped with English target words in (a) orthography (ВЕЛЮР [vʲɪ'lʲʉr]-BERRY), (b) phonology (БЛАНК [blank]-BLOOD), or (c) had no orthographic or phonological overlap (КАЛАЧ [kɐ'lat͡ɕ]-BERRY; ГЖЕЛЬ [ɡʐϵlʲ]-BLOOD). The results of this study showed a clear and strong benefit of the parafoveal preview of Russian words that shared either orthography or phonology with English target words. This study is the first demonstration of cross-script orthographic and phonological parafoveal preview benefit effects. Bilinguals integrate orthographic and phonological information across eye fixations in reading, even when this information comes from different languages.

Phonological processing dynamics in bilingual word naming

The current study investigated phonological processing dynamics in bilingual word naming. English-French and French-English bilinguals named interlingual heterophonic homographs (i.e., words that share orthography but not meaning or pronunciation across languages), heterophonic cognates (i.e., words that share both orthography and meaning across languages, but not pronunciations), interlingual homophones (i.e., words that share pronunciation, but not orthography or meaning across languages), and single-language matched control words in both English and French naming tasks. Cross-language phonological activation was strongest in bilinguals' second language. The results provided evidence for feedforward activation of phonological representations in the nontarget language, as well as feedback activation of these phonological representations from semantic representations. Results are interpreted within the more recent Bilingual Interactive Activation (BIA+) framework.

Cross-language phonological activation: evidence from masked onset priming and ERPs

The goal of the present research was to provide direct evidence for the cross-language interaction of phonologies at the sub-lexical level by using the masked onset priming paradigm. More specifically, we investigated whether there is a cross-language masked onset priming effect (MOPE) with L2 (English) primes and L1 (Russian) targets and whether it is modulated by the orthographic similarity of primes and targets. Primes and targets had onsets that overlapped either only phonologically, only orthographically, both phonologically and orthographically, or did not have any overlap. Phonological overlap, but not orthographic overlap, between primes and targets led to faster naming latencies. In contrast, the ERP data provided evidence for effects of both phonological and orthographic overlap. Finally, the time-course of phonological and orthographic processing for our bilinguals mirrored the time-course previously reported for monolinguals in the ERP data. These results provide evidence for shared representations at the sub-lexical level for a bilingual's two languages.

The activation of phonological representations by bilinguals while reading silently: Evidence from interlingual homophones

These experiments investigated whether bilinguals activate phonological representations from both of their languages when reading silently in one. The critical stimuli were interlingual homophones (e.g., sank in English and cinq in French). French-English and English-French bilinguals completed an English lexical decision task. Decisions made by French-English bilinguals were significantly faster and more accurate for interlingual homophones than for matched English control words. In subsequent experiments, the homophone facilitation effect in the latency data disappeared when distractors were changed to pseudohomophones, when cognates and interlingual homographs were added to the experiment, and when the proportion of critical stimuli was decreased. However, the homophone effect in the error data remained. In contrast, English-French bilinguals revealed little evidence of an interlingual homophone effect. Several attempts were made to increase the saliency of the nontarget language, however these manipulations produced only a small effect in the error data. These results indicate that the activation of phonological representations can appear to be both language-specific and nonspecific depending on the proficiency of the bilinguals and whether they are reading in their weaker or stronger language.

Understanding print: early reading development and the contributions of home literacy experiences

This study explored the development of children's early understanding of visual and orthographic aspects of print and how this is related to early reading acquisition. A total of 474 children, ages 48 to 83 months, completed standardized measures of phonological awareness and early reading skills. They also completed experimental tasks that tapped their understanding of what constitutes "readable" print. The parents of participants completed a questionnaire regarding their children's home literacy experiences. The data showed systematic development in children's understanding of print conventions and English orthography and spelling. Regression analyses indicated that print knowledge was related to early reading skill, even after accounting for variance due to age and phonological awareness. Furthermore, parents' ratings of the extent of their children's involvement in activities that led to practice in reading and writing most consistently predicted the development of emerging literacy skills, including understanding of the conventions of the English writing system. Little relation between print knowledge and the frequency of storybook reading by adults was observed.

Masked priming of prefixes and the influence of spelling-meaning consistency

Two experiments are reported which examined whether a prefixed word can be primed by a word sharing only the prefix letters in a masked priming paradigm. In addition the studies examined whether the size of the priming effect is influenced by the consistency with which a prefix letter pattern appears in real prefixed words. The ratio of real prefixed words to all words containing a prefix letter pattern was calculated and used to identify high-consistency prefixes, which are frequently used as prefixes (e.g., UN in UNHAPPY) and rarely appear as pseudoprefixes (e.g., UNCLE), and low-consistency prefixes, which appear in many pseudoprefixed words (e.g., DE in DESERT) but fewer truly prefixed words (e.g., DECODE). In Experiment 1, decision latencies for both types of prefixes were facilitated when real prefixed target words were preceded by real prefixed prime words in a short SOA masked priming paradigm, although the size of the priming effect for low-consistency prefixes was similar in size to that for orthographic controls. In Experiment 2, real prefixed target words were preceded by pseudoprefixed prime words. Facilitation in performance remained for high-consistency prefixes but was absent for low-consistency prefixes. These results support models of morphological processing that are sensitive to the statistical nature of the relationships between orthographic and semantic representations in a language.

Homophone effects in lexical decision

The role of phonology in word recognition was investigated in 6 lexical-decision experiments involving homophones (e.g., MAID-MADE). The authors' goal was to determine whether homophone effects arise in the lexical-decision task and, if so, in what situations they arise, with a specific focus on the question of whether the presence of pseudohomophone foils (e.g., BRANE) causes homophone effects to be eliminated because of strategic deemphasis of phonological processing. All 6 experiments showed significant homophone effects, which were not eliminated by the presence of pseudohomophone foils. The authors propose that homophone effects in lexical decision are due to the nature of feedback from phonology to orthography.

Exposure to print and word recognition processes

The effect of exposure to print on the efficiency of phonological and orthographic word recognition processes was examined by comparing two groups of university students having similar reading comprehension scores but different levels of exposure to print. Participants with a high level of exposure to print were faster and more accurate in naming pseudowords, in choosing the correct member of a homophone pair, and in making lexical decisions when nonwords were pseudohomophones. In the lexical decision task, low-print-exposure participants were more sensitive to the frequency of the orthographic patterns in the stimuli. The results of a form priming task demonstrated that high-print-exposure participants more quickly and strongly activated the orthographic representations of common words and subsequently more strongly activated the corresponding phonological representations. Even among successful students, differences in exposure to print produce large differences in the efficiency of both orthographic and phonological word recognition processes.

The role of phonology in the activation of word meanings during reading: evidence from proofreading and eye movements

Six experiments explored the role of phonology in the activation of word meanings when words were embedded in meaningful texts. Specifically, the studies examined whether participants detected the substitution of a homophone mate for a contextually appropriate homophone. The frequency of the incorrect homophone, the frequency of the correct homophone, and the predictability of the correct homophone were manipulated. Also, the impact of reading skill was examined. When correct homophones were not predictable and participants had a range of reading abilities, the evidence indicated that phonology plays a role in activating the meanings of low-frequency words only. When the performance of good and poor readers was examined separately, the evidence indicated that good readers primarily activate the meanings of words using the direct route, whereas poor readers primarily activate the meanings of words using the phonological route.

Applications of binary and analog hydrogenated amorphous silicon/ferroelectric liquid-crystal optically addressed spatial light modulators

Analytical and experimental results that show novelty filtering, optical phase conjugation, and real-time edge enhancement by using optically addressed spatial light modulators that comprise amorphous silicon photodiodes and analog and binary ferroelectric liquid-crystal modulators are presented. The advantages of these devices for the above applications include high-speed, low-power operation and high spatial resolution.

Naming multisyllabic words

The process of reading multisyllabic words aloud from print was examined in 4 experiments. Experiment 1 used multisyllabic words that vary in terms of the consistency of component spelling-sound correspondences. The stimuli were regular, regular inconsistent, and exception words analogous to the monosyllabic items used in previous studies. Both regular inconsistent and exception words produced longer naming latencies than regular words. In Experiment 2 these differences between word types were found to be limited to lower frequency items. Experiment 3 showed that effects of number of syllables on naming latency are also limited to lower frequency words when the stimulus display forced subjects to use syllabic units. Thus, frequency modulates the effects of two aspects of lexical structure-consistency of spelling-sound correspondences and number of syllables. The results suggest that the naming of multisyllabic words draws on some of the same knowledge representations and processes as monosyllabic words; however, naming does not require syllabic decomposition. The results are discussed in the context of current models of naming.
