The aim of this study was to explore the relationship between paternal attitudes, father-child activities, socioeconomic and sociodemographic factors, and the early child productive vocabulary. We also wanted to study if paternal factors affected boys' and girls' language acquisition differently. Our data consisted of 722 fathers and their…

This cross-linguistic study investigated whether the native language has any influence on lexical composition among Italian (N = 125) and Finnish (N = 116) very preterm (born at <32 gestational weeks) children at 24 months (controls: 125 Italian and 146 Finnish full-term children). The investigation also covered the effect of maternal education…

It is not well understood how grammar emerges in very-low-birth-weight (VLBW) children. The main aim of the present study was to gain information on the emergence of grammar in this group at 2; 0. The Finnish version of the Communicative Development Inventory was used to collect data from VLBW children ("N" = 156) and full-term controls…

Many children experience recurrent acute otitis media (RAOM) in early childhood. In a previous study, 2-year-old children with RAOM were shown to have immature neural patterns for speech sound discrimination. The present study further investigated the consonant inventories of these same children using natural speech samples. The results showed…

Growth modeling was applied to monolingual (N = 26) and bilingual (N = 28) word learning from 14 to 36 months. Level and growth rate of vocabulary were lower for Finnish-Russian bilinguals than for Finnish monolinguals. Processing of Finnish speech sounds at 7 but not at 11 months predicted level, but not growth rate of vocabulary in both Finnish…

This study investigated the potential interrelationship between parental (maternal) and expert assessments of the expressive and receptive language skills of 12- to 18-month-old children. The language activities of 27 children were monitored by their mothers (MCDI scale: Lyytinen, 2000. "Varhaisen kommunikaation ja kielen kehityksen…

In this follow-up study, we evaluated children's communication development at the ages of 8 ("n" = 50), 18 ("n" = 46), 24 ("n" = 44) and 36 months ("n" = 36) using the Finnish version of the "MacArthur Communicative Developmental Inventories" (MCDI). A sample of children ("n" = 14)…

The aim of the present study was to analyze early vocalization development, the predictive value of this development in terms of later language skills, and possible gender difference in early vocalization development in a selected cohort of 32 very-low-birth-weight (VLBW) children and 35 full-term controls. The data on early vocalization…

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…

A fundamental question in developmental science is how brains with and without language compute numbers. Measuring young children's verbal reactions in Spain and Finland, we show that, although there is a general arithmetic ability for small numbers that is shared by monkeys and preverbal infants, the development of such initial knowledge in…

The relationship between late-talkers' language development and reading and spelling outcomes was examined in children with and without familial risk for dyslexia. The late-talking subgroups were defined using parent- and test-based assessments of receptive and expressive vocabulary and grammar at 2 and 2.5 years as intake criteria. The language…
