Study Notes

Development of an Individual

  • Two main factors influence development: heredity (nature) and environment (nurture)
  • Heredity is the transmission of traits from parents to offspring
  • Environment is the sum of experiences a person encounters from conception to old age

Heredity

  • Sex cells (egg and sperm) meet during fertilization
  • Gonads are reproductive organs that produce sex cells
  • Spermatozoa are male sex cells produced in the testes
  • Ova are female sex cells produced in the ovaries
  • A zygote is a fertilized egg cell containing hereditary potentials from both parents
  • Chromosomes are thread-like structures inside the nucleus of cells
  • Females always contribute an X chromosome
  • Males contribute either an X or Y chromosome
  • XX chromosomes result in female offspring
  • XY chromosomes result in male offspring
  • Genes are basic units of heredity within chromosomes
  • DNA (deoxyribonucleic acid) is a substance found within genes and contains hereditary information

Maturation

  • Unfolding of inherited traits
  • Stages of human development include pre-natal, infancy, babyhood, early childhood, late childhood, puberty, adolescence, early adulthood, middle age, and old age

Pre-Natal Period

  • Conception to birth
  • Divided into three stages: germinal, embryonic, and fetal

Infancy

  • From birth to the end of the second week

Babyhood

  • From the end of the second week to the end of the second year

Early Childhood

  • Also known as the preschool age
  • 2-6 years old

Late Childhood

  • Also known as the elementary age
  • 6-10 years old

Puberty

  • Also known as preadolescence
  • 12-13 or 14 years

Adolescence

  • 13 or 14-18 years

Early Adulthood

  • 18-40 years

Middle Age

  • 40-60 years

Old Age

  • 60 years to death
