Published: May 2022

This study tried to replicate and extend the semantic transparency morphological effect using the flanker lexical decision paradigm (Grainger et al., 2020). In the first experiment, stems were used as flankers of target words that could be truly morphological (), pseudomorphological (), or form-related with the flanker (). In half of the trials, a related flanker was employed, and in the other half, an unrelated word was presented as flanker (e.g., ). The results showed a facilitative effect for the related condition as a main effect with no difference between experimental conditions. These results were interpreted in terms of an orthographic facilitation taking place when whole stems are presented as flankers. In the second experiment, short derivational suffixes were used as flankers of the same targets employed in the first experiment. The results showed an inhibitory effect of the same magnitude for the transparent and pseudomorphological conditions with no effect for the form condition. This finding suggests an inhibitory effect by which morphemes activate several lexical candidates that compete for recognition. Overall, the results are interpreted in terms of the cognitive requirements of the experimental task, the items selected, and the current models of morphological processing.

Having a detailed description of the psycholinguistic properties of a language is essential for conducting well-controlled language experiments. However, there is a paucity of databases for some languages and regional varieties, including Québec French. The SyllabO+ corpus was created to provide a complete phonological and syllabic analysis of a corpus of spoken Québec French.

Orthographic and Meaning Processes in Reading Chinese Compounds: Comparisons Between L1 and L2 Reading.

Article Synopsis
  • Research explores the timing of orthographic (visual) and semantic (meaning) processes in reading complex words, particularly using Chinese characters that clearly show morphemes.
  • Four priming experiments were conducted to see how native Chinese speakers (L1) and Chinese learners (L2) differ in their reading processes, focusing on how well they understand the language’s lexical quality.
  • Findings reveal that L1 readers quickly recognize orthographic effects even with short exposure, while L2 readers show both effects only with longer exposure, suggesting that understanding of morphological meanings improves with experience.

The agri-food sector is undergoing a comprehensive transformation as it transitions towards net zero. To achieve this, fundamental changes and innovations are required, including changes in how food is produced and delivered to customers, new technologies, data and physical infrastructures, and algorithmic advancements. In this paper, we explore the opportunities and challenges of deploying AI-based data infrastructures for sustainability in the agri-food sector by focusing on two case studies: soft-fruit production and brewery operations.

Article Synopsis
  • Surface dyslexia and dysgraphia are key traits of semantic variant primary progressive aphasia (svPPA), particularly in English, but pose challenges in languages like Italian that have clearer spelling-pronunciation relationships.
  • Regularization errors occur when individuals with svPPA fail to recognize exceptions in language rules, such as incorrect inflection of irregular verbs.
  • The Italian Verb Inflection Test (IVIT) effectively identifies svPPA by demonstrating higher regularization errors in verb inflection compared to other types of Alzheimer's disease, offering a viable diagnostic tool for Italian speakers.
