Language processing encompasses a sophisticated interplay of phonological (sound-based) and semantic (meaning-based) processes. This intricate interaction develops progressively during early language acquisition. It involves not only the addition of new words to the child's vocabulary but also the evolving organization of lexico-semantic networks. The aim of the current research was to investigate how young children navigate the complexities of word relationships, with a focus on the interplay between phonological similarity and semantic relatedness. A preferential looking experiment was conducted involving 73 participants divided into two age groups, with 39 aged 18 months and 34 aged 24 months. The experimental design involved auditory presentation of target words together with pairs of target and distractor images that systematically varied the phonological and semantic similarity between the pairs. The results showed a significant developmental progression in young children's phonological and semantic processing abilities. At 18 months, children predominantly responded to phonological cues, displaying challenges in distinguishing between phonologically similar words regardless of semantic context. By 24 months, there was an evident sensitivity to both phonological and semantic cues. This age group especially showed processing difficulties with words that were both phonologically similar and semantically related, suggesting a more complex integration of lexico-semantic networks. These findings underscore the pivotal role of phonological processing in early language acquisition and point to the gradual integration of semantic relationships into children's lexicons.

Introduction: Numerous studies have explored the linguistic and executive processes underlying verbal fluency using association designs, which provide limited evidence. To assess the validity of our model, we aimed to refine the cognitive architecture of verbal fluency using an interference design.
Methods: A total of 487 healthy participants performed letter and semantic fluency tests under the single condition and dual conditions while concurrently performing a secondary task that interferes with speed, semantics, phonology, or flexibility.

Background: Tractography allows the in vivo study of subcortical white matter, and it is a potential tool for providing predictive indices on post-operative outcomes. We aim at establishing whether there is a relation between cognitive outcome and the status of the inferior fronto-occipital fasciculus's (IFOF's) microstructure.
Methods: The longitudinal neuropsychological data of thirty young (median age: 35 years) patients operated on for DLGG in the left temporo-insular cortex along with pre-surgery tractography data were processed.

Background: The defective spoken output of persons with aphasia has anomia as a main clinical manifestation. Improving anomia is therefore a main goal of any language treatment.
Aim: This study assessed the effectiveness of a novel, 2-week, rehabilitation protocol (PHOLEXSEM), focused on PHonological, SEmantic, and LExical deficits, aiming at improving lexical retrieval, and, generally, spoken output.

Background And Purpose: Despite comprehensive evidence that supports the utility of aphasia therapy in persons with chronic (≥6 months) stroke-induced aphasia, the amount of therapy provided to patients in the United States is typically far less than what is likely necessary to maximize recovery. Two potential contributors to this discrepancy are limited access to rehabilitation services due to the availability of providers and logistical difficulties with transportation. One way to increase access to aphasia therapy is to rely on telerehabilitation.

We report a case of crossmodal bilingual aphasia-aphasia in two modalities, spoken and sign language-and dysgraphia in both writing and fingerspelling. The patient, Sunny, was a 42 year-old woman after a left temporo-parietal stroke, a speaker of Hebrew, Romanian, and English and an adult learner, daily user of Israeli Sign language (ISL). We assessed Sunny's spoken and sign languages using a comprehensive test battery of naming, reading, and repetition tasks, and also analysed her spontaneous-speech and sign.
