Insights

Thai infants show distinct gross motor development patterns compared to Canadian norms, with significant differences in early and later infancy. This study provides culturally relevant Alberta Infants Motor Scale (AIMS) percentiles for Thai infants.

Area of Science:

  • Pediatrics
  • Developmental Pediatrics
  • Cross-Cultural Studies

Background:

  • The Alberta Infants Motor Scale (AIMS) is a widely used tool for assessing infant gross motor development.
  • Cross-cultural variations in child-rearing practices necessitate culturally specific developmental norms.
  • This study addresses the need for localized AIMS percentiles in Thailand.

Purpose of the Study:

  • To establish an AIMS percentile curve for typically developing, home-raised infants in northeastern Thailand.
  • To compare the gross motor development of Thai infants with established Canadian norms.

Main Methods:

  • The Thai version of the AIMS was administered to 574 full-term infants (15 days to 14 months).
  • Percentile curves for gross motor ability were generated.
  • Thai infants' mean AIMS scores were compared to Canadian norms using a one-sample t-test.

Main Results:

  • AIMS scores increased with age in Thai infants, with notable inter-individual variability between 7 and 10 months.
  • Thai infants scored significantly lower than Canadian norms in the first three months (P < 0.05).
  • Thai infants scored significantly higher than Canadian norms at 7-<8 months, 11-<12 months, and 13-14 months.

Conclusions:

  • The developed AIMS percentile curve is relevant for infants within similar Thai demographic and environmental contexts.
  • The findings highlight natural inter-variability in gross motor development across cultures, particularly between 7 and 10 months of age.

Three Developmental Domains

Human development is typically examined across three main domains: physical, cognitive, and socio-emotional. These domains represent the significant areas of change and continuity throughout the lifespan, from infancy to late adulthood.
Physical Development
Physical processes, also known as maturation, encompass the biological changes that occur across an individual's life. These changes begin with genetic inheritance and continue through various stages, including growth in height and weight,...

Introduction to Developmental Psychology

Developmental psychology explores the changes and continuities in human abilities throughout life, encompassing physical, cognitive, linguistic, and social dimensions. Human development is not restricted to growth, but includes aspects of decline, particularly in physical abilities as individuals age. Developmental psychologists seek to understand how people change as they age and how their mental and social skills evolve.Developmental MilestonesA key concept in developmental psychology is...
