This study applies the Phonological Mean Length of Utterance measurement (PMLU; Ingram & Ingram, 2001; Ingram, 2002) to the data of five children acquiring Finnish and evaluates their phonological development longitudinally at four different age points: 2;0, 2;6, 3;0, and 3;6. The children's results on PMLU and related measures are discussed together with remarks on individual differences regarding the acquisition of consonants, consonant clusters and word length. During the period analyzed the children's phonetic inventories increase and they gradually overcome the constraints against long words and consonant sequences. The PMLU method's ability to reflect the qualitative changes and individual differences between the children is found to be limited in some respects, although overall development can be noted in the values. The PMLU method's strengths and weaknesses are evaluated critically and improvements suggested.

While the multiple cognitive deficits model of reading difficulties (RD) is widely supported, different cognitive-linguistic deficits may manifest differently depending on language and writing system characteristics. This study examined cognitive-linguistic profiles underlying RD in Hebrew, characterised by rich Semitic morphology and two writing versions differing in orthographic consistency-a transparent-pointed version and a deep-unpointed version. A two-step cluster analysis grouped 96 s graders and 81 fourth graders based on their phonological awareness (PA), rapid naming (RAN), orthographic knowledge (OK) and morphological-pattern identification (MPI) abilities.

Childhood apraxia of speech (CAS) is a motor speech disorder in which the precision and consistency of speech sounds are impaired due to deficits in motor planning and programming. The literature on CAS suggests that the clinical features of CAS cannot be limited to one level of speech processing and that a more comprehensive understanding of how all levels involved in speech production are part of a complex system is needed. The aim of this study was to investigate the relationship between phonological and speech motor abilities in children with CAS and to determine the extent to which speech motor performance accounts for phonological processing in children with CAS.

Background/objectives: Previous studies have examined the role of working memory in cognitive tasks such as syntactic, semantic, and phonological processing, thereby contributing to our understanding of linguistic information management and retrieval. However, the real-time processing of phonological information-particularly in relation to suprasegmental features like tone, where its contour represents a time-varying signal-remains a relatively underexplored area within the framework of Information Processing Theory (IPT). This study aimed to address this gap by investigating the real-time processing of similar tonal information by native Cantonese speakers, thereby providing a deeper understanding of how IPT applies to auditory processing.

The underlying causes of reading impairment in neurodegenerative disease are not well understood. The current study seeks to determine the causes of surface alexia and phonological alexia in primary progressive aphasia (PPA) and typical (amnestic) Alzheimer's disease (AD). Participants included 24 with the logopenic variant (lvPPA), 17 with the nonfluent/agrammatic variant (nfvPPA), 12 with the semantic variant (svPPA), 19 with unclassifiable PPA (uPPA), and 16 with AD.

Introduction: Autism spectrum disorder (ASD) is characterized by impairments in social interactions, social communication, and repetitive and stereotyped patterns of behavior. Previous studies have reported mixed findings regarding the links between language (i.e.
