Prepotent task-irrelevant semantic information is dampened by domain-specific control mechanisms during visual word recognition.

We investigated whether semantic interference occurring during visual word recognition is resolved using domain-general control mechanisms or using more specific mechanisms related to semantic processing. We asked participants to perform a lexical decision task with taboo stimuli, which induce semantic interference, as well as a semantic Stroop task and a Simon task, intended as benchmarks of linguistic-semantic and non-linguistic interference, respectively. Using a correlational approach, we investigated potential similarities between effects produced in the three tasks, both at the level of overall means and as a function of response speed (delta-plot analysis). Correlations selectively surfaced between the lexical decision and the semantic Stroop task. These findings suggest that, during visual word recognition, semantic interference is controlled by semantic-specific mechanisms, which intervene to face prepotent but task-irrelevant semantic information interfering with the accomplishment of the task's goal.

Selective suppression of taboo information in visual word recognition: Evidence for cognitive control on semantics.

The present study investigated the role of cognitive control on semantic information during visual word recognition by exploiting taboo stimuli in a lexical-decision task. We relied on delta plots and electromyography (EMG) to assess different hypothetical mechanisms of cognitive control. Previous research suggests that taboo stimuli slow down the performance across a variety of tasks due to their attention-grabbing nature. One possibility is that cognitive control counteracts the detrimental effects of taboo connotation by actively dampening such prepotent yet task-irrelevant information. Consistent with this hypothesis, we found a reversal of taboo interference effect in slowest responses, signaling the deployment of a selective suppression mechanism that needs time to fully accrue. For electromyographic data, we focused on partial errors (trials showing a subthreshold activation of the incorrect response hand) to index response-monitoring processes intervening to prevent and correct errors. We found no modulation of the likelihood of partial errors and, more generally, of response accuracy as a function of taboo connotation. Taken together, the results suggest that cognitive control may intervene to selectively suppress fast-acting and distracting taboo information, indicating a controlled semantic processing that optimizes activation to match task-relevant goals.

Controlling speed in component skills of reading improves the explanation of reading comprehension.

Efficiency in reading component skills is crucial for reading comprehension, as efficient subprocesses do not extensively consume limited cognitive resources, making them available for comprehension processes. Cognitive efficiency is typically measured with speeded tests of relatively easy items. Observed responses and response times indicate the latent variables of ability and speed. Interpreting only ability or speed as efficiency may be misleading because there is a within-person dependency between both variables (speed–ability tradeoff [SAT]). Therefore, the present study measures efficiency as ability conditional on speed by controlling speed experimentally with item-level time limits. The proposed timed ability measures of reading component skills are expected to have a clearer interpretation in terms of efficiency and to be better predictors for reading comprehension. To support this claim, this study investigates two component skills, visual word recognition and sentence-level semantic integration (sentence reading), to understand how differences in ability in a timed condition are related to differences in ability and speed in a traditional untimed condition. Moreover, untimed and timed reading component skill measures were used to explain reading comprehension. A German subsample from Programme for International Student Assessment (PISA) 2012 completed the reading component skills tasks with and without item-level time limits and PISA reading tasks. The results showed that timed ability is only moderately related to untimed ability. Furthermore, timed ability measures proved to be stronger predictors of sentence-level and text-level reading comprehension than the corresponding untimed ability and speed measures, although using untimed ability and speed jointly as predictors increased the amount of explained variance.

The effect of visual cues in e-books on pre-K children’s visual attention, word recognition, and comprehension: An eye tracking study

This study explored how pre-K children process an e-book with narration through eye movements, and also the effects of visual cues on preschoolers’ visual attention to text, word recognition, and comprehension. Data were collected from eight children attending a university-associated daycare center. Eye tracker was used to record the participants’ eye movements while interacting with the e-book. Although the participants understood the story, only two of them showed an increase in the word recognition test. The obtained eye movement data demonstrated that the children focused more on the pictures (82.31%) than on the text (15.56%), which is a result that is higher than found in previous studies (e.g., Evans & Saint-Aubin, 2005; Justice et al., 2005; Takacs & Bus, 2018). Overall, 51.71% of their fixations on text matched with the visual cues synchronized with the narration. This study was limited to a single reading session of a short storybook, and employed a small sample size.

Interaction between Phonological and Semantic Processes in Visual Word Recognition using Electrophysiology.

Controversies have always existed in research related to reading abilities; on whether printed words are perceived in a feedforward manner based on orthographic information after which, other representations, such as phonology and semantics are activated, or whether these are fully interactive and high-level semantic information affects early processing. An interference paradigm was implemented in the presented protocol of phonological and semantic judgment tasks that utilized the same precede-target pairs to explore the relative order of phonological and semantic activation. The high- and low-frequency target words were preceded with three conditions: semantically related, phonological-related (homophones), or unrelated. The results showed that the induced P200 component of low-frequency word pairs was significantly greater than high-frequency words in both the semantic and phonological tasks. In addition, both the homophones in the semantic task and the semantically related pairs in the phonological task caused reduction in N400 when compared to the the control condition, word frequency-independently. It is worth noting that for the low-frequency pairs in the phonological judgment task, the P200 released by the semantically related word pairs was significantly larger than that in the control condition. Overall, semantic processing in phonological tasks and phonological processing in semantic tasks were found in both high- and low-frequency words, suggesting that the interaction between semantics and phonology may operate in a task-independent manner. However, the specific time this interaction occurred may have been affected by the task and frequency.

The time course of processing handwritten words: An ERP investigation

Behavioral studies have shown that the legibility of handwritten script hinders visual word recognition. Furthermore, when compared with printed words, lexical effects (e.g., word-frequency effect) are magnified for less intelligible (difficult) handwriting (Barnhart and Goldinger, 2010; Perea et al., 2016). This boost has been interpreted in terms of greater influence of top-down mechanisms during visual word recognition. In the present experiment, we registered the participants' ERPs to uncover top-down processing effects on early perceptual encoding. Participants' behavioral and EEG responses were recorded to high- and low-frequency words that varied in script's legibility (printed, easy handwritten, difficult handwritten) in a lexical decision experiment. Behavioral results replicated previous findings: word-frequency effects were larger in difficult handwriting than in easy handwritten or printed conditions. Critically, the ERP data showed an early effect of word-frequency in the N170 that was restricted to the difficult-to-read handwritten condition. These results are interpreted in terms of increased attentional deployment when the bottom-up signal is weak (difficult handwritten stimuli). This attentional boost would enhance top-down effects (e.g., lexical effects) in the early stages of visual word processing.

Letter processing in Russian: Does orthography matter?

Prior research has suggested that the identification and encoding of letter positions within letter strings might be influenced by orthography. Letters in transparent languages (e.g., Greek) with regular grapheme-to-phoneme correspondences are processed sequentially, whereas letters in deep languages (e.g., English) are processed in parallel. In three experiments, we used a visual search paradigm to test this hypothesis on Russian—a relatively transparent language. In Experiment 1, we measured the identification speed of Cyrillic letters at each position in the five-element real words or pronounceable pseudowords. In Experiment 2, the performance was compared to random letter strings, and in Experiment 3, to non-linguistic symbol strings. Our results reveal a search pattern similar to English, excluding strictly serial letter computation, which is inconsistent with the orthography hypothesis. Moreover, we showed that the lexical status and the nature of the string (linguistic/non-linguistic) affect response times for Russian and therefore must be accounted for in models of visual word recognition.

Age-related evaluations of imageability and subjective frequency for 1286 neutral and emotional French words: ratings by young, middle-aged, and older adults.

This study aimed at providing imageability and subjective frequency ratings collected from four adult age groups ranging from 18 to 85 years old (18-25; 26-39; 40-59; and 60 and over) for 1286 neutral and emotional French words available in the EMA database (Gobin et al., 2017). Overall, the older adults rated words as more (subjectively) frequent and more imageable than the younger adults. Furthermore, we examined the relationships between subjective frequency and imageability, as well as those with emotional variables (i.e., valence, arousal) already available for these words, for each age group. For all age groups, more subjective frequent words were more imageable. Emotional words were more imageable and more frequent. Arousal scores were lower for low- and high-imageability words, and higher for more subjective frequent words. The strength of these links between subjective frequency, imageability, and emotional ratings was found to decrease as a function of age. Finally, by using the lexical decision reaction times and accuracy rates of young adults from Megalex (Ferrand et al., 2018), imageability and subjective frequency across age were found to provide an additional contribution to visual word recognition performance as compared to objective lexical variables (i.e., number of letters, syllables, objective frequency, orthographic neighborhood). More importantly, subjective frequency and imageability ratings from the youngest group predicted reaction times and accuracy better than ratings from the oldest group. By providing new age-adapted word characteristics, this norm should be of great use to researchers in the field of cognitive aging who use word materials.

Iconicity and Second Language Visual Perception: A Psycholinguistic Study of English Imitative Words at Different De-iconization Stages

The study of iconicity, i.e., of a link between form and meaning in a word based on similarity, has gained increased attention in recent years. Although recent research has shown an important role of iconicity for first language acquisition, its role for the second language (L2) acquisition is still unclear, neither is it understood how the perception of imitative words depends on their iconic expressiveness. We applied a multivariate experimental plan with repeated measurements and experimental and control stimuli to study visual recognition of English iconic (imitative) words at four stages of de-iconization (SDs) by native speakers of Russian (N = 106) using a lexical decision task. The participants were presented with an experimental stimulus and had to decide as rapidly as possible whether a visually presented letter string was a word or not. The method of diachronic evaluation was used to group the pre-selected imitative words into four categories where SD-1 words are the most vivid imitative words with an evident (iconic) link between form and meaning, and SD-4 words are the words which have lost this link in the course of language (semantic and phonetic) evolution. The findings have revealed that proceeding speed and accuracy rates are strongly connected to SDs: the less iconic (imitative) a word is, the faster and more accurately it is recognized; most iconic words (SD-1) are characterized by the slowest RTs and lowest accuracy rates. The results suggest that iconicity does affect visual recognition of imitative words by second language learners.

The impact of capitalized German words on lexical access.

Leading models of visual word recognition assume that the process of word identification is driven by abstract, case-invariant units (e.g., table and TABLE activate the same abstract representation). But do these models need to be modified to meet nuances of orthography as in German, where the first letter of common nouns is capitalized (e.g., Buch [book] and Hund [dog], but blau [blue])? To examine the role of initial capitalization of German words in lexical access, we chose a semantic categorization task ("is the word an animal name?"). In Experiment 1, we compared German words in all-lowercase vs. initial capitalization (hund, buch, blau vs. Hund, Buch, Blau). Results showed faster responses for animal nouns with initial capitalization (Hund < hund) and faster responses for lowercase non-nouns (blau < Blau). Surprisingly, we found faster responses for lowercase non-animal nouns (buch < Buch). As the latter difference could derive from task demands (i.e., buch does not follow German orthographic rules and requires a "no" response), we replaced the all-lowercase format with an orthographically legal all-uppercase format in Experiment 2. Results showed an advantage for all nouns with initial capitalization (Hund < HUND and Buch < BUCH). These findings clearly show that initial capitalization in German words constitutes an essential part of the words' representations and is used during lexical access. Thus, models of visual word recognition, primarily focused on English orthography, should be expanded to the idiosyncrasies of other Latin-based orthographies.

Effect of Handwriting on Visual Word Recognition in Chinese Bilingual Children and Adults.

In a digital era that neglects handwriting, the current study is significant because it examines the mechanisms underlying this process. We recruited 9- to 10-year-old Chinese children (n = 24), who were at an important period of handwriting development, and adult college students (n = 24), for both behavioral and electroencephalogram (EEG) experiments. We designed four learning conditions: handwriting Chinese (HC), viewing Chinese (VC), drawing shapes followed by Chinese recognition (DC), and drawing shapes followed by English recognition (DE). Both behavioral and EEG results showed that HC facilitated visual word recognition compared to VC, and behavioral results showed that HC facilitated visual word recognition compared to drawing shapes. HC and VC resulted in a lateralization of the N170 in adults, but not in children. Taken together, the results of the study suggest benefits of handwriting on the neural processing and behavioral performance in response to Chinese characters. The study results argue for maintaining handwriting practices to promote the perception of visual word forms in the digital age.

Early Top-Down Modulation in Visual Word Form Processing: Evidence From an Intracranial SEEG Study.

Visual word recognition, at a minimum, involves the processing of word form and lexical information. Opinions diverge on the spatiotemporal distribution of and interaction between the two types of information. Feedforward theory argues that they are processed sequentially, whereas interactive theory advocates that lexical information is processed fast and modulates early word form processing. To distinguish between the two theories, we applied stereoelectroencephalography (SEEG) to 33 human adults with epilepsy (25 males and eight females) during visual lexical decisions. The stimuli included real words (RWs), pseudowords (PWs) with legal radical positions, nonwords (NWs) with illegal radical positions, and stroked-changed words (SWs) in Chinese. Word form and lexical processing were measured by the word form effect (PW versus NW) and lexical effect (RW versus PW), respectively. Gamma-band (60 ∼ 140 Hz) SEEG activity was treated as an electrophysiological measure. A word form effect was found in eight left brain regions (i.e., the inferior parietal lobe, insula, fusiform, inferior temporal, middle temporal, middle occipital, precentral and postcentral gyri) from 50 ms poststimulus onset, whereas a lexical effect was observed in five left brain regions (i.e., the calcarine, middle temporal, superior temporal, precentral, and postcentral gyri) from 100 ms poststimulus onset. The two effects overlapped in the precentral (300 ∼ 500 ms) and postcentral (100 ∼ 200 ms and 250 ∼ 600 ms) gyri. Moreover, high-level regions provide early feedback to word form regions. These results demonstrate that lexical processing occurs early and modulates word form recognition, providing vital supportive evidence for interactive theory.SIGNIFICANCE STATEMENT A pivotal unresolved dispute in the field of word processing is whether word form recognition is obligatorily modulated by high-level lexical top-down information. To address this issue, we applied intracranial SEEG to 33 adults with epilepsy to precisely delineate the spatiotemporal dynamics between processing word form and lexical information during visual word recognition. We observed that lexical processing occurred from 100 ms poststimulus presentation and even spatiotemporally overlapped with word form processing. Moreover, the high-order regions provided feedback to the word form regions in the early stage of word recognition. These results revealed the crucial role of high-level lexical information in word form recognition, deepening our understanding of the functional coupling among brain regions in word processing networks.

Training of Word Recognition with Willy Wordbear: A Syllable-Based Reading Promotion Program for Elementary School

Training of Word Recognition with Willy Wordbear: A Syllable-Based Reading Promotion Program for Elementary School Being able to read words fluently and accurately is an important milestone in learning to read but not all children reach it. For weak readers, it is often difficult to make the transition from letter-by-letter reading to visual word recognition through orthographic comparison processes using larger (sub-)lexical units. The syllable seems to provide a bridge to orthographic decoding for children who learn to read German. Against this background, this replication study investigated the effectiveness of a syllable-based reading training on the visual word recognition and reading comprehension of second graders in an experimental pre-post design. To this end, 101 children whose word recognition performance in a standardized reading test was below the mean value in comparison to the classroom norm were randomly assigned to the experimental group or a waiting control group. Linear models revealed significant improvements in orthographic decoding in the experimental group after completion of the 24-session small group training. Children who received the training of repeated reading and segmentation of frequent syllables were able to recognize words faster and more accurately. These findings are further evidence of the effectiveness of the training for promoting the recognition of written words.

Are better young readers more likely to confuse their mother with their mohter?

One of the most replicated effects in the contemporary word recognition literature is the transposed-letter effect (TL effect): pseudowords created by the transposition of two letters (e.g., MOHTER) are often misread as the real word. This effect ruled out those accounts that assume that letter position is encoded accurately and led to more flexible coding schemes. Here, we examined whether reading skill modulates this effect. The relationship between reading skill and the TL effect magnitude is a contentious issue both empirically and theoretically. The present lexical decision experiment was designed to shed some light on the relationship between reading skill and the TL effect magnitude with a large sample of Grade 6 children. To that end, we conducted both multiple regression and path analyses. Results showed that a specific aspect of reading skills (pseudoword reading) negatively correlates with the TL effect's magnitude in the error data (i.e., MOHTER is less wordlike for better readers). This finding highlights the need for a comprehensive visual-word recognition model that includes individual variability and the multidimensional character of reading in school-age children.

Modified Geometrical Method For Visual Lip Extraction From Color Images

Lip Reading or Speech recognition is a visual way of communicating. It depends on watching the speaker's mouth; Especially his lips to understand the letters and words of the speaker. Through the visual image (the form of the expression of the mouth) and the movement of the lips, visual recognition of spoken letters, words, and sentences is made; Gestures and expressions on the face. the position of the mouth and its extracted features help to understand the visual speech more clearly. Researchers are always trying to find the new methods to increase the efficiency of the lip reading systems. for this reason, This paper presents a lip localization. based face detection &features extraction strategy to segment mouth region from input video frames. we have used RGB &HSV color model along with modified channel factor and then applying more edge detection techniques and morphological operations to be a new one of the visual speech recognition tools.

Examining L1 influence in L2 word recognition

Abstract The present study examined L1 influence in visual L2 word recognition in the area of letter case. Whether an English word is displayed in upper- or lower-case letters may be of little significance to English native speakers, but many ESL speakers from east Asia have found it more difficult to recognize words printed in upper-case letters. Two experiments were conducted to explore two questions: (a) whether there was indeed a case effect in L2 word recognition in that ESL speakers took longer in responding to upper-case words, and (b) whether this case effect only occurred for ESL speakers whose first languages employed a script other than the Roman alphabet. The participants included English native speakers, ESL speakers whose L1s employed the Roman alphabet (the Romance ESL group) and ESL speakers whose L1s did not. They were asked to perform a lexical decision task on English words displayed in either upper- or lower-case letters. In both experiments, a reliable case effect was found for the latter ESL group only. This L1-related case effect raised both theoretical and pedagogical issues to be explored in future research.

Neural correlates of confusability in recognition of morphologically complex Korean words.

When people confuse and reject a non-word that is created by switching two adjacent letters from an actual word, is called the transposition confusability effect (TCE). The TCE is known to occur at the very early stages of visual word recognition with such unit exchange as letters or syllables, but little is known about the brain mechanisms of TCE. In this study, we examined the neural correlates of TCE and the effect of a morpheme boundary placement on TCE. We manipulated the placement of a morpheme boundary by exchanging places of two syllables embedded in Korean morphologically complex words made up of lexical morpheme and grammatical morpheme. In the two experimental conditions, the transposition syllable within-boundary condition (TSW) involved exchanging two syllables within the same morpheme, whereas the across-boundary condition (TSA) involved the exchange of syllables across the stem and grammatical morpheme boundary. During fMRI, participants performed the lexical decision task. Behavioral results revealed that the TCE was found in TSW condition, and the morpheme boundary, which is manipulated in TSA, modulated the TCE. In the fMRI results, TCE induced activation in the left inferior parietal lobe (IPL) and intraparietal sulcus (IPS). The IPS activation was specific to a TCE and its strength of activation was associated with task performance. Furthermore, two functional networks were involved in the TCE: the central executive network and the dorsal attention network. Morpheme boundary modulation suppressed the TCE by recruiting the prefrontal and temporal regions, which are the key regions involved in semantic processing. Our findings propose the role of the dorsal visual pathway in syllable position processing and that its interaction with other higher cognitive systems is modulated by the morphological boundary in the early phases of visual word recognition.

Chew on this! Oral stereognosis predicts visual word recognition in typical adults

Much work has been conducted that reports on the strong relationships between speech production and reading behaviour. However, disentangling the relative contribution of the various underlying speech mechanisms (i.e., articulation, somatosensory and/or auditory) that contribute to this relationship remains unknown. Oral stereognosis refers to the ability to discriminate shapes using our tongue/mouth, in the absence of seeing the shape beforehand, and is a measure of the somatosensory sub-system of the speech mechanism. In this work, we aimed to address the extent to which oral stereognosis predicted visual word recognition. Methods: Healthy participants ranging from 18 to 51 years old (N = 60; Mage = 22.7) completed the Florida Oral Recognition Measurement (FORM) task and two visual word recognition tasks. The FORM required participants to identify carrots that were cut into the following letters’ shapes: E, R, T, S, L, N, O, V. Carrot letters were randomly presented to participants. With respect to the visual word recognition tasks, participants were required to press a button: 1) if the letter string spelled a word or 2) if the letter string sounded like a word. Response time and accuracy were measured for all tasks. Results: Participants were divided into high (accuracy >50%) vs. low (accuracy ≦ 50%) oral stereognosis recognition groups. For the high FORM group, oral stereognosis recognition predicted visual word recognition in the spell task (Adj R2 = .114). For the low FORM group, oral stereognosis recognition predicted visual word recognition in the sound task (Adj R2 = .307). Together, these findings provide evidence that oral stereognosis is predictive of word recognition performance, and that performance on the FORM differentially predicts word recognition tasks (spell vs. sound). Overall, these findings inform current print-to-speech frameworks by identifying a relationship between sensorimotor information, specifically, oral stereognosis ability, and reading performance.

Affect across adulthood: Evidence from English, Dutch, and Spanish.

Emotions play a fundamental role in language learning, use, and processing. Words denoting positivity account for a larger part of the lexicon than words denoting negativity, and they also tend to be used more frequently, a phenomenon known as positivity bias. However, language experience changes over an individual's lifetime, making the examination of the emotion-laden lexicon an important topic not only across the life span but also across languages. Furthermore, existing theories predict a range of different age-related trajectories in processing valenced words. The present study pits all of these predictions against written productions (Facebook status updates from over 20,000 users) and behavioral data from three publicly available megastudies on different languages, namely English, Dutch, and Spanish, across adulthood. The production data demonstrated an increase in positive word types and tokens with advancing age. In terms of comprehension, the results showed a uniform and consistent effect of valence across languages and cohorts based on data from a visual word recognition task. The difference in reaction times to very positive and very negative words declined with age, with responses to positive words slowing down more strongly with age than responses to negative words. We argue that the results stem from lifelong learning and emotion regulation: Advancing age is accompanied by an increased type frequency of positive words in language production, which is mirrored as a discrimination penalty in comprehension. To our knowledge, this is the first study to simultaneously target both language production and comprehension across adulthood and in a cross-linguistic perspective.
