Two event-related brain potential experiments were conducted to investigate whether there is a functional primacy of syntactic structure building over semantic processes during Chinese sentence reading. In both experiments, we found that semantic interpretation proceeded despite the impossibility of a well-formed syntactic analysis. In Experiment 1, we found an N400 difference between combined syntactic category and semantic violations and single syntactic violations. This finding is inconsistent with earlier German and French studies (e.g., Friederici, Gunter, Hahne, & Mauth, 2004; Friederici, Steinhauer, & Frisch, 1999; Hahne & Friederici, 2002) showing that semantic integration does not proceed for words of the wrong syntactic category. In Experiment 2, we used a design that was very similar to that used in earlier German and French studies, but semantic violations still evoked an N400, irrespective of a simultaneous syntactic category violation. We argue against processing models that do not allow for semantic integration of a word unless it can be grammatically attached to the developing phrase structure tree. Rather, language experience may modulate the mode of interplay between syntax and semantics.

This paper studies the role of eye tracking in detecting grammatical violation in reading tasks. It tests the assumption that encountering syntactic violation has its correspondence in the behavioral patterns associated with gazing. Applying the offered by the research environment , it is shown that the observation of grammaticality/agrammaticality in samples of experiments is reflected in the partial correlation of these categories across a number of structural patterns.

This study investigates the emergence of prepositions in Hebrew-speaking children aged 2;6-6;0 years, analyzing a peer talk corpus of 75 children across five age groups. Across 45-minute triadic conversations, we examined the distributions, semantic functions, and form-function relations of prepositions. Two results sections are presented.

Article Synopsis
- Language is a productive system, allowing children to create new utterances they've never heard before, making it tricky to determine when they first demonstrate linguistic productivity.
- Researchers conducted a study with 64 English-learning children, examining when they started to combine determiners and nouns in ways not seen in their caregivers' speech.
- By combining behavioral data and computational modeling, they found that the children were generating unique combinations similar to the model, indicating that they too were creatively using language beyond their prior experiences.

Article Synopsis
- * The dataset was originally in Spanish, translated into English, and preprocessed to ensure quality by removing duplicates and missing values, focusing on women with an average age of 53.
- * Various machine learning models, including KNN, SVM, and advanced models like BERT and BioGPT, were evaluated for their effectiveness in classifying BI-RADS categories using NLP techniques to extract meaningful information from the reports.
