The label-feedback effect is influenced by target category in visual search.

The label-feedback hypothesis states that language can modulate visual processing. In particular, hearing or reading aloud target names (labels) speeds up performance in visual search tasks by facilitating target detection and such advantage is often measured against a condition where the target name is shown visually (i.e. via the same modality as the search task). The current study conceptually complements and expands previous investigations. The effect of a multimodal label presentation (i.e., an audio+visual, AV, priming label) in a visual search task is compared to that of a multimodal (i.e. white noise+visual, NV, label) and two unimodal (i.e. audio, A, label or visual, V, label) control conditions. The name of a category (i.e. a label at the superordinate level) is used as a cue, instead of the more commonly used target name (a basic level label), with targets belonging to one of three categories: garments, improper weapons, and proper weapons. These categories vary for their structure, improper weapons being an ad hoc category (i.e. context-dependent), unlike proper weapons and garments. The preregistered analysis shows an overall facilitation of visual search performance in the AV condition compared to the NV condition, confirming that the label-feedback effect may not be explained away by the effects of multimodal stimulation only and that it extends to superordinate labels. Moreover, exploratory analyses show that such facilitation is driven by the garments and proper weapons categories, rather than improper weapons. Thus, the superordinate label-feedback effect is modulated by the structural properties of a category. These findings are consistent with the idea that the AV condition prompts an "up-regulation" of the label, a requirement for enhancing the label's beneficial effects, but not when the label refers to an ad hoc category. They also highlight the peculiar status of the category of improper weapons and set it apart from that of proper weapons.

Effect of short-term intensive design-based STEM learning on executive function: an fNIRS study of the left-behind children.

Design-based STEM learning is believed to be an effective cross-disciplinary strategy for promoting children's cognitive development. Yet, its impact on executive functions, particularly for disadvantaged children, still need to be explored. This study investigated the effects of short-term intensive design-based STEM learning on executive function among left-behind children. Sixty-one Grade 4 students from a school dedicated to the left-behind children in China were sampled and randomly assigned to an experimental group (10.70 ± 0.47 years old, n = 30) or a control group (10.77 ± 0.43 years old, n = 31). The experimental group underwent a two-week design-based STEM training program, while the control group participated in a 2-week STEM-related reading program. Both groups were assessed with the brain activation from 4 brain regions of interest using functional near-infrared spectroscopy (fNIRS) and behavioral measures during a Stroop task before and after the training. Analysis disclosed: (i) a significant within-group time effect in the experimental group, with posttest brain activation in Brodmann Area 10 and 46 being notably lower during neutral and word conditions; (ii) a significant between-group difference at posttest, with the experimental group showing considerably lower brain activation in Brodmann Area 10 and Brodmann Area 46 than the control group; and (iii) a significant task effect in brain activity among the three conditions of the Stroop task. These findings indicated that this STEM learning effectively enhanced executive function in left-behind children. The discrepancy between the non-significant differences in behavioral performance and the significant ones in brain activation implies a compensatory mechanism in brain activation. This study enriches current theories about the impact of Science, Technology, Engineering, and Mathematics (STEM) learning on children's executive function development, providing biological evidence and valuable insights for educational curriculum design and assessment.

The home literacy environment of school-age autistic children with high support needs.

BACKGROUND: As a group, autistic children with high support needs (with adaptive functioning in the range of an intellectual disability) are at risk of significant literacy difficulties. We investigated the parent-reported home literacy environment of this group of children. METHOD: Sixty-two parents of autistic children (4.5 to 18.25 years) attending an autism-specific school completed a home literacy survey reporting on their child's: (1) alphabet knowledge, (2) interest in reading, (3) activities/interactions around books, (4) reading ability, and (5) writing ability. RESULTS: We found significant positive correlations between parent-reported child interest in reading and literacy-related interactions and skills, but not with child age. Children using spoken words to communicate obtained significantly greater scores on four home-literacy subscales, but not on reading interest. CONCLUSIONS: A better understanding of the home literacy activities of autistic children with high-support needs is needed to inform educational practices aimed at promoting literacy development in this vulnerable population.

Alignment of behaviour and tDCS stimulation site induces maximum response: evidence from online tDCS and ERP.

tDCS modulates the activity of the neuronal networks to induce the desired behavioural changes. Two factors determine its effectiveness- (1) whether the network being stimulated is relevant to the task, and (2) if there is a scope for improvement in behavioral performance. To explore this, both dorsal (sub-lexical) and ventral (lexical) reading networks were stimulated (20 min, 2 mA) in 25 healthy young volunteers. Participants performed two reading tasks with different levels of lexical involvement: word fragment completion tasks (WCT) and word association tasks (WAT), while event-related potentials (ERPs) were recorded simultaneously. The study used a within-subject design over three sessions, comparing various electrode montages targeting the dorsal pathway's left inferior parietal lobule or the ventral reading pathway's left middle temporal lobule, as well as sham stimulation. The impact of tDCS sessions (dorsal, ventral, & sham) and task type (WCT & WAT) on priming effects (primed vs. unprimed) of behavioral performance (accuracy and reaction times), and ERP parameters (N400 amplitudes and latencies) were statistically analyzed.It was found that tDCS modulated the performance of WAT only (a task with a lower priming effect). The failure to modulate WCT (larger priming effect) indicated that tDCS was effective for conditions with room for improvement compared to a task where performance has reached the ceiling. Ventral stimulation enhanced accuracy in the WAT condition and shortened the N400 latency of the priming effect. In contrast, dorsal stimulation delayed the priming effect reaction time in the WAT condition and enhanced the N400 amplitude. To conclude, enhancement in performance due to tDCS occurs when the network (ventral) being stimulated aligns with the cognitive demands of the task and there is a scope for improvement.

Both mOTS-words and pOTS-words prefer emoji stimuli over text stimuli during a lexical judgment task.

The visual word form area in the occipitotemporal sulcus (here OTS-words) is crucial for reading and shows a preference for text stimuli. We hypothesized that this text preference may be driven by lexical processing. Hence, we performed three fMRI experiments (n = 15), systematically varying participants' task and stimulus, and separately evaluated middle mOTS-words and posterior pOTS-words. Experiment 1 contrasted text with other visual stimuli to identify both OTS-words subregions. Experiment 2 utilized an fMRI adaptation paradigm, presenting compound words as texts or emojis. In experiment 3, participants performed a lexical or color judgment task on compound words in text or emoji format. In experiment 2, pOTS-words, but not mOTS-words, showed fMRI adaptation for compound words in both formats. In experiment 3, both subregions showed higher responses to compound words in emoji format. Moreover, mOTS-words showed higher responses during the lexical judgment task and a task-stimulus interaction. Multivariate analyses revealed that distributed responses in pOTS-words encode stimulus and distributed responses in mOTS-words encode stimulus and task. Together, our findings suggest that the function of the OTS-words subregions goes beyond the specific visual processing of text and that these regions are flexibly recruited whenever semantic meaning needs to be assigned to visual input.

Tracking the brain signature of (mis)spelled logotypes via letter transpositions and replacements.

All leading models of visual word recognition assume a hierarchical process that progressively converts the visual input into abstract letter and word representations. However, the results from recent behavioral studies suggest that the mental representations of words with a highly consistent visual format, such as logotypes, may comprise not only purely abstract information but also perceptual information. This hypothesis would explain why participants often misperceive transposed-letter misspellings with the original base words to a larger degree in logotypes (e.g., SASMUNG, but not SARVUNG, is perceived as SAMSUNG) than in common words. The present experiment examined the electrophysiological signature behind the identification of correctly spelled and misspelled logotypes (via letter transposition or replacement) in an ERP go/no-go semantic categorization experiment. Results showed that N400 amplitudes for transposed-letter misspelled logotypes (SASMUNG) and intact logotypes (SAMSUNG) did not differ significantly across various time windows (until 600 ms), whereas replacement-letter misspelled logotypes (SARVUNG) yielded consistently larger N400 amplitudes. These findings reveal that the mental representations of logotypes are particularly resistant to minor orthographic changes, which has important theoretical and applied (e.g., marketing) implications.

Cortical cognitive processing during reading captured using functional-near infrared spectroscopy.

Neuroimaging studies using functional magnetic resonance imaging (fMRI) have provided unparalleled insights into the fundamental neural mechanisms underlying human cognitive processing, such as high-level linguistic processes during reading. Here, we build upon this prior work to capture sentence reading comprehension outside the MRI scanner using functional near infra-red spectroscopy (fNIRS) in a large sample of participants (n = 82). We observed increased task-related hemodynamic responses in prefrontal and temporal cortical regions during sentence-level reading relative to the control condition (a list of non-words), replicating prior fMRI work on cortical recruitment associated with high-level linguistic processing during reading comprehension. These results lay the groundwork towards developing adaptive systems to support novice readers and language learners by targeting the underlying cognitive processes. This work also contributes to bridging the gap between laboratory findings and more real-world applications in the realm of cognitive neuroscience.

Working Memory Capacity and Contextual Novel Linguistic Input: A Cross-Modal Priming Study on Persian-English Subordinate Bilinguals.

The present study investigated the effect of verbal working memory capacity (VWMC) on the processing of semantic information during on-line lexical ambiguity resolution of bilinguals. Seventeen Persian-English subordinate bilinguals of similar proficiency level were recruited to perform two experimental tasks: (1) a multi-load-level reading span task designed to measure their VWMC and (2) a cross-modal semantic priming task (CMPT), 24 h subsequent to the last encoding session, to assess their performance on semantic processing of L2 homographs whose subordinate readings were deemed "novel" for them. An overall 2 × 3 repeated-measures ANOVA revealed a statistically significant difference in the processing of the encoded semantic information between high and low WMC participants. The findings of the experiments lend support to the veracity of the assumptions made by Reordered Access Model in that biasing semantic context facilitates the ambiguity resolution of lexical items. Lastly, the pedagogical implications of the findings were expounded on.

Processing causal structure sentences in Mandarin Chinese: an eye movements study.

It remains uncertain whether causal structure prediction can improve comprehension in Chinese sentences and whether the position of the headword mediates the prediction effect. We conducted an experiment to explore the effect of causal prediction and headword position in Chinese sentence reading. Participants were asked to read sentences containing causal connectives with their eye movements recorded. In the experiment, we manipulated the causal structure of the sentence and the position of the headword. We found a promoting effect of causal structure on first-pass reading time and a hindering impact on total reading time. However, the effect was not mediated by the headword position. The results show that causal syntactic prediction facilitated early-stage processing and increased the integration cost in the late stage of Chinese sentence processing. These findings also support the constraint-based approach, which suggests an isolation between semantic and syntactic processing.

Increasing inter-word spacing reduces migration errors and improves reading comprehension in students with dyslexia.

We report a small study in which we explored the effects of manipulating narrative text on levels of comprehension for students with and without dyslexia. Using two pieces of standardised narrative text deemed to be of similar difficulty and length, we manipulated the texts such that we could present two texts to each participant, one in each condition. The first condition was text using standard inter-word spacing; the second condition used increased inter-word spacing. Scores on standardised comprehension questions were significantly improved for participants with dyslexia. Additionally, given that there is evidence of delayed visual attention disengagement in individuals with specific forms of dyslexia, we hypothesised that the phenomena of migration of letters and words for some readers might be mitigated by increasing inter-word spacing. We did indeed find that incidence of migration was significantly reduced in this condition for all participants.

On relative word length and transposed-word effects.

It is harder to decide that a sequence of words is ungrammatical when the ungrammaticality is created by transposing two words in a correct sentence (e.g., he wants green these apples), and it is harder to judge that two ungrammatical word sequences are different when the difference is created by transposing two words (e.g., green want these he apples-green these want he apples). In two experiments, we manipulated the relative length of the transposed words such that these words were either the same length (e.g., then you see can it) or different lengths (e.g., then you create can it). The same-length and different-length conditions were matched for syntactic category and word frequency. In Experiment 1 (speeded grammatical decision) we found no evidence for a modulation of transposed-word effects as a function of the relative length of the transposed words. We surmised that this might be due to top-down constraints being the main driving force behind the effects found in the grammatical decision task. However, this was also the case in Experiment 2 (same-different matching with ungrammatical sequences of words) where syntactic constraints were minimized. Given that skilled readers can read sentences composed of words of the same length, our results confirm that word length information alone is not used to encode the order of words in a sequence of words, and especially concerning the order of adjacent words in foveal/parafoveal vision.

Processing of Counterfactual Conditional Sentences with Differential Propositional Truth-Value in Mandarin Chinese: Evidence from ERP.

Although many studies document the role of propositional truth-value in human psychological reading behavior, there is a relative paucity of research examining the role of differential propositional truth-value in processing Chinese counterfactual conditionals. This study is to investigate the role of differential propositional value in processing Chinese counterfactual conditionals by means of ERPs (event-related potentials). The study is based on comprehending two types of Chinese counterfactual conditionals, which is propositional truth value introduced by two different markers of conditional conjunctions in the protasis and apodosis, such as true counterfactual conditional markers jiaru (if) & jiu (so) in the sentence wo xiang yu jiaru you tui jiu keyi zai shuixia zhixi (I think if fish had legs so they could stifle under water), and false counterfactual conditional markers ruguo (if) & namo (then) in the sentence wo xiang gou ruguo you lin namo keyi zai shuixia huxi (I think if dogs had scales, then they could breathe under water). Two counterfactual propositional values (i.e. true and false propositional values) are constructed through manipulating sentence counterfactuality between the true and false counterfactual conditional markers in the protasis and the apodosis. Twenty-four full-time Chinese college students participated in the ERP study. The results demonstrated that processing the true counterfactual propositional sentences with conditional markers jiaru (if) & jiu (so) elicited the N400 effect relative to false propositional sentences with conditional markers ruguo (if) & namo (then). Moreover, the counterfactual sentences with true propositional conditions varied from the elicitation of the N400 effect in the protasis and absence of the N400 effect in the apodosis, showing that semantic roles may gradually disappear under the impact of truth value of propositional counterfactual condition, and/or the roles of semantic anomaly was eliminated in the accumulated sentence processing. While for the false counterfactual conditional sentences, elicitations of P300 in the protasis and robust N400 effect in the apodosis were shown, indicating the increasing semantic role in the processing. Interestingly, there was the absence of the P600 effect for processing sentences with syntactic violation, suggesting little extra syntactic cost in processing sentences with false propositional condition.

Phonological remediation effects on a child with giftedness and developmental dyslexia. / Efeito da remediação fonológica em criança com altas habilidades/superdotação e dislexia do desenvolvimento.

Twice-exceptionality is characterized as the presence of high performance concomitantly with deficiencies or incompatible conditions. An example is when giftedness manifest associated with neurodevelopmental disorders. This study is a clinical case report referring to the evaluative and interventional process of a 9- year-old child with the paradoxical combination of giftedness associated with dyslexia. It aims to compare the performance in phonological processing, reading and writing before and after phonological remediation. In the first assessment, the child demonstrated alphabetic level in reading, a transition phase between syllabic-alphabetic and alphabetical writing levels, and below-expected performance in phonological processing skills. After intervention, the results showed consistent improvements in phonological processing, the consolidation of alphabetical writing and orthographic reading level. In general, children with isolated dyslexia have persistent difficulties in several skills after intervention. The evolution shown after phonological remediation, especially at reading level, shows different characteristics than expected. Thus, it can be concluded that twice-exceptionality may have favored the overcoming of some of the shown difficulties more successfully. Studies on these combined conditions can contribute to a better understanding of this framework during the development of learning and to formulate specialized interventions.

A dupla-excepcionalidade é caracterizada pela presença de alto desempenho concomitante a deficiências ou condições incompatíveis, como é o caso de altas habilidades associadas a transtornos do neurodesenvolvimento. Esse estudo é um relato de caso clínico referente ao processo avaliativo e interventivo de uma criança de 9 anos com a combinação paradoxal de altas habilidades associadas à dislexia. O objetivo foi comparar o desempenho nas tarefas de processamento fonológico, leitura e escrita pré e pós remediação fonológica. Na primeira avaliação, a criança apresentou nível alfabético na leitura, fase de transição entre os níveis silábico-alfabético e alfabético na escrita e desempenho abaixo do esperado nas habilidades do processamento fonológico. Após a intervenção, houve melhora em habilidades do processamento fonológico, consolidação da escrita alfabética e do nível ortográfico de leitura. Em geral, crianças com dislexia isolada apresentam dificuldades persistentes em várias habilidades após intervenção. A evolução demonstrada após a remediação fonológica, principalmente no nível de leitura, mostra características diferentes do esperado. Assim, pode-se concluir que a dupla-excepcionalidade pode ter favorecido a superação de algumas de suas dificuldades de forma mais exitosa. Estudos sobre estas condições combinadas podem contribuir para a melhor compreensão deste quadro durante o desenvolvimento da aprendizagem e para a formulação de intervenções especializadas.

The perceptual span in dyslexic reading and visual search.

Many studies have attempted to identify the root cause of dyslexia. Different theories of dyslexia have proposed either a phonological, attentional, or visual deficit. While research has used eye-tracking to study dyslexia, only two previous studies have used the moving-window paradigm to explore the perceptual span in dyslexic reading, and none have done so in visual search. The present study analysed the perceptual span using both reading and visual search tasks to identify language-independent attentional impairments in dyslexics. We found equivocal evidence that the perceptual span was impaired in dyslexic reading and no evidence of impairment in visual search. However, dyslexic participants did show deficits in the visual search task, with lower search accuracy and shorter saccades compared with controls. These results lend support for a visual, rather than attentional or phonological, account of dyslexia.

Reading books: The positive impact of print exposure on written word recognition.

Regular print exposure is thought to benefit reading and language processes: those who read more have a larger vocabulary and better spelling and comprehension skills. Yet, there is little or no direct evidence that exposure to print facilitates reading. Here, we used an ecologically valid design to test the impact of print exposure on the early stages of reading in skilled adult readers. Participants read a novel at their own pace. Reading was followed by a lexical decision task, in which the positive trials were words that were exposed in the novel, and matched controls not exposed in the novel. If exposure during reading had a positive impact on subsequent word recognition, exposed words would be processed more efficiently than not-exposed words (exposure effect). This effect was obtained in three experiments. In addition, the effect was not modulated by the amount of exposure (1 vs. 3 occurrences in the text; Experiment 1), or the timing between reading and the exposure test (immediately after reading vs. on the following day; Experiment 3). However, the effect was present only in low-frequency words (Experiment 3). Interpretations of the exposure effect in terms of activation threshold and lexical quality are discussed.

When social hierarchy matters grammatically: Investigation of the processing of honorifics in Korean.

Korean grammar encodes relative social hierarchies among interlocutors in various ways. This study utilized honorific subject-verb agreement in Korean to investigate how social hierarchies are processed during sentence comprehension. The experimental results showed that honorific violations elicited processing difficulties. The use of an honorific verb with an unhonorifiable subject resulted in lower naturalness ratings, longer reading times, and elicited a P600, similar to effects observed with number, person, and gender agreement in Spanish or English. These findings suggest that social hierarchies have become integrated into grammar, constraining how native Korean speakers process sentences. However, the agreement between honorific subjects and verbs seems asymmetrical; the mismatch effect was smaller or absent when an honorifiable subject was not accompanied by an honorific verb, suggesting that while an honorific verb requires an honorifiable subject, the reverse is not necessarily true. The results indicate that the -si agreement in Korean is a form of morpho-syntactic agreement, despite its asymmetrical nature.

A study of the effects of four reading styles on college students' mental health and quality of life based on positive psychology-A first-of-its-kind study.

BACKGROUND: The increase in mental health problems among college students has become a global challenge, with anxiety and depression in particular becoming increasingly prevalent. Positive psychology has gained attention as an important psychological intervention that emphasizes improving mental health by promoting positive emotions and mindfulness. However, with the diversity of reading styles, however, there is a lack of systematic research on these effects. Therefore, this study aims to explore the specific effects of different reading styles on college students' mental health and quality of life based on positive psychology, with the aim of providing more effective interventions and recommendations for improving college students' mental health. METHODS: This study used a two-round questionnaire to select students with mental health problems and divided them into four experimental groups with a control group. The study was conducted by distributing questionnaires and experimental interventions, and a total of 2860 valid questionnaires were collected. The study used the Self-Assessment Scale for Anxiety (SAS) and the Self-Depression Scale (SDS) to assess the participants' anxiety and depression levels. In addition, the study used the Physical Composite Score (PCS) and the Mental Composite Score (MCS) to assess the participants' quality of life. SPSS 26.0 was used for data statistics and repeated measures ANOVA was used. RESULTS: Paper text reading and audio reading methods were effective in reducing anxiety levels and improving sleep quality. However, the electronic text reading approach was less effective compared to paper text reading and audio reading, and the video reading approach was not effective in improving depression. In addition, the positive psychology literature reading intervention showed significant improvements in college students' quality of life scores. CONCLUSION: The results of this study suggest that paper text reading and audio reading modalities have a positive impact on the mental health and quality of life of college students, while e-text reading and video reading modalities are less effective. These findings provide suggestions for college students to choose appropriate reading styles and further demonstrate the effectiveness of positive psychology reading on mental health. These results have important academic and practical implications for promoting mental health and improving quality of life among college students.

Presentation matters: Surface text features and text quality in written narratives of Dutch high school students with and without dyslexia.

Presentation features such as spelling, punctuation and handwriting can influence the evaluation of general text quality. High school students with dyslexia might therefore be at a disadvantage, as at least their spelling performance is typically poor(er). Furthermore, these students might show less sophisticated linguistic features of texts, such as word length and sentence complexity, that might also be related to text quality. We compared narratives written by Dutch high school students (mean age 13.7 years) with (n = 28) and without (n = 29) dyslexia. Students with dyslexia's texts contained more spelling errors and poorer handwriting quality, but not more punctuation errors. Teacher-rated general text quality was lower for the texts of students with dyslexia in uncorrected versions. When spelling and punctuation errors were corrected, no teacher-rated text quality differences emerged. No differences in linguistic text features were found. Furthermore, spelling, punctuation and, to a lesser extent, number of words per sentence clause were related to ratings of text quality across participants. These results confirm the influence of presentation features on text quality rating. They encourage teachers to be aware of this effect and emphasize the importance of spelling and writing support and interventions for students with dyslexia throughout education.

Correction to effects of a visual perception-based occupational therapy programme on reading and motor skills in children with developmental dyslexia: Single blind randomised crossover study design.

This study aimed to examine the effects of a visual praxis-based occupational therapy (VPOT) programme on reading and motor skills for children with developmental dyslexia (DD). Forty-two children were included in the study. Additionally, before VPOT, the Reading-Aloud and Reading-Comprehension Test 2 (ORSRC-2) and the Bruininks-Oseretsky Motor-Proficiency-Test-2-Brief Form (BOT2-BF) were applied to the participants. According to the study design, VPOT was applied to two sessions per week for 8 weeks to group A. During this period, group B was accepted as the control group. At the end of these 8 weeks, evaluation tests were applied to both groups. Then, group A was defined as the control group and Group B as the intervention group, and VPOT was applied to Group B. At the end of another 8 weeks, evaluation tests were applied to both groups for the third time. When the final ORSRC-2 results were examined, VPOT was found to be an effective programme for improving reading skills. Additionally, when the final BOT2-BF results were examined, VPOT was determined to be effective in improving motor skills (p < 0.05). We believe that it is important to carry out comprehensive studies such as the VPOT programme to solve problems in the physical and learning activities of children with DD.
