Previous research has demonstrated conflicting findings concerning orthographic access in older age. The current study examines whether older adults rely more heavily on stored knowledge while spelling, through testing of word concreteness. Forty-one younger (age 20-29), 41 middle age (age 45-55), and 40 healthy older adults (age 70-80) spelled 60…

This paper addresses how input variability in the adult phonological system is mastered in the output of young children in Akan, a Kwa language spoken in Ghana, involving variability between labio-palatalized consonants and front rounded vowels. The high-frequency variant involves a complex consonant which is expected to be mastered late, while…

Aims: To describe typical phonological development of Brazilian Portuguese (BP)-speaking children, considering the following parameters: age of customary production, acquisition and mastery. Methods & Procedures: Data were collected from 857 children aged between 3 years and 8 years 11 months with typical language and speech development. The…

The study aimed at evaluating the diadochokinetic (DDK) skills of Greek-speaking preschool children with phonological disorder (PD) by means of a structured evaluation protocol and at proposing cut-off points for children at risk of speech impairment. The participants were 36 children with PD and 60 typically developing (TD) peers. The groups were…

The extent of quantitative and qualitative differences in phonological development between bilingual children and their monolingual counterparts remains unresolved, especially with regard to typologically-related languages. The current study used a comparative research design to examine the phonological skills of preschool children speaking Polish…

This study examined the impact of the lexical distance (spoken, modern standard Arabic-MSA, shared, and pseudo-words) on phonological awareness (PA) and naming speed (RAN). The data from this longitudinal study were obtained from 261 native Arabic-speaking kindergarteners, which were then followed to first grade. The data revealed a significant…

The age at which people acquire a word influences word recognition, known as the age of acquisition (AoA) effect. In the first language (L1), AoA effects are widely found in various languages and experimental tasks. Arbitrary Mapping Hypothesis proposes that AoA effects reflect the loss of network plasticity during the learning of mappings between…

Purpose: As a class, fricatives are more "resistant" to consonant-vowel coarticulation than other English sounds. This study investigates the relative coarticulatory resistance of /[voiceless dental fricative], s, [voiceless palato-alveolar fricative]/ in child and adult speech to better understand the acquisition of individuated speech…

Purpose: Identifying appropriate targets for vocabulary instruction and determining the optimal sequence for instruction continue to be a challenge. The purpose of this study is to investigate how previously studied lexical characteristics collectively influence children's word learning. Method: A secondary data analysis was conducted using the…

Purpose: The aim of this study was to explore when and how Mandarin-speaking children use contextual cues to normalize speech variability in perceiving lexical tones. Two different cognitive mechanisms underlying speech normalization (lower level acoustic normalization and higher level acoustic-phonemic normalization) were investigated through the…

Purpose: Identifying appropriate targets for vocabulary instruction and determining the optimal sequence for instruction continue to be a challenge. The purpose of this study is to investigate how previously studied lexical characteristics collectively influence children's word learning. Method: A secondary data analysis was conducted using the…

Purpose: We sought to provide valid and reliable data on the acquisition of consonant sounds in speakers of Brazilian Portuguese. Method: The sample comprised 733 typically developing monolingual speakers of Brazilian Portuguese (ages 3;0-8;11 [years;months]). The presence of surface speech error patterns, the revised percentage consonants…

Background: Dutch is a West-Germanic language spoken natively by around 24 million speakers. Although studies on typical Dutch speech sound development have been conducted, norms for phonetic and phonological characteristics of typical development in a large sample with a sufficient age range are lacking. Aim: To give a detailed description of the…

The study analysed spectral and tongue shape dynamics of voiceless alveolar and postalveolar fricatives produced by ten children learning Scottish English. Synchronised ultrasound tongue imaging data and acoustic data were used to characterise children's productions of the phonemic contrast. Six children had consistently accurate productions of…

Purpose: This study examines intraword variability in 40 typically developing French-speaking monolingual and bilingual children, aged 2;6-4;8 (years;months). Specifically, it measures rate of intraword variability and investigates which factors best account for it. They include child-specific ones such as age, expressive vocabulary, gender,…
