This study extends the methodological and theoretical understanding of executive functions (EFs) in preschoolers from low- and middle-income countries (LMIC). First, the authors describe a rigorous process of adapting and evaluating six EF tasks to produce a culturally and developmentally appropriate measure of emerging EFs in a large sample of…

A study of fundamental vocal frequency values in 14 children aged 11 to 25 months, an age period characterized by changes in physiological and linguistic development, is reported. A developmental trend downward in vocal frequencies is traced across a number of previous studies, but is only tentative and is not documented in the age group under…

A study of 80 children, aged 7, 10, 13, and 16, found that gender was not an important variable in speech breathing, but age was. The youngest group exhibited such things as larger lung, rib cage, and abdominal volume initiations and terminations for breath groups and fewer syllables per breath group. (Author/JDD)

The questionnaire examined (1) ages perceived as dividing points between adolescence, childhood and adulthood; (2) tasks seen as most important in advancing from one period…

It should now be recognized that every child has at least five parallel ages: A "chronological" age, in years, months, and days: a "physiological" age, indicative of physical growth and maturity; a "mental" age, significant of intellectual capacity and ability; a "school standing," or "pedagogical"…
