Study Notes
- Human Development, Part 1 focuses on prenatal and infant development.
Daily Objectives
- Define ages of human development stages from life to death.
- Define the stages of prenatal development, which are the stages the fetus goes through before birth
- Characterize in-utero human perception and what fetuses perceive.
- Define the term teratogen, give examples, and describe the effects on developing organisms.
- Explain how preferential looking is used to measure infant perception.
- Describe major patterns in motor development.
Human Development Study
- The study of human development examines continuity and change across a person's lifespan.
- The course explores continuity and change across sensation and perception, cognition and language, emotion, and social and moral behavior.
- Four main periods of human development covered are:
- Prenatal period and infancy (conception - 2-3 years)
- Childhood (2-3 – 11 years)
- Adolescence (12 – ??? years)
- Adulthood (??? years – death)
- Significant changes occur during these periods
- Early experiences in infancy are crucial to normal development and for the myriad of individual differences observed across the human population.
- In utero experiences shape the human organism prior to birth.
- Taste preference may begin in the womb based on the mother's eating habits and sensory capabilities like sight, smell and hearing.
Prenatal Development
- Human experience starts with conception.
- Prenatal development occurs in the time before birth which include:
- Germinal stage lasting 0-2 weeks
- Embryonic stage lasting 3-8 weeks
- Fetal stage lasting 9 weeks to birth
Brain Development
- Much experience and learning occur during the fetal period through:
- Neurogenesis
- Myelination
- Synaptogenesis
- Synaptic Pruning
Fetal Sensation
- The womb is not a vacuum and fetuses can experience stimuli in utero.
- Stimuli include tastes, smells, sounds, and tactile sensations.
- The fetal heartbeat changes in reaction to external voices being played, differently to music than speech.
- Newborns recognize their mother's language and voice minutes after birth.
Teratogens
- Not every experience in utero is positive; teratogens are external agents that cause damage/death during prenatal development.
- Teratogens mostly affect fetuses during critical/sensitive periods.
Neonatal Period
- The average neonate (newborn) spends most of the day sleeping, roughly 2/3 of the day
- Be able to interpret diagrams illustrating hours of total sleep, REM sleep and NREM sleep.
Perceptual Development
- Perceptual development begins in utero, but after birth, perceptual experiences are much richer.
- Sensation involves sensory organs detecting of physical signals, and is "filtered" in utero.
- Perception is the organization/interpretation of sensory information into coherent understanding.
Measuring Infants' Perception
- Optometrists measure visual acuity and color vision, and infants' abilities can be measured as well.
- Preferential looking is one method.
- Infants prefer looking at objects or events that are interesting, stimulating, or familiar.
Visual Acuity
- Infants will look longer at something more interesting, which reveals visual acuity.
- In the first month, infants' visual acuity improves from approximately 20/400 to 20/120.
- Adult-like acuity is achieved by 6 months.
- Color and depth perception develop in the first 6 months, too.
Motor Development in Infancy
- Perception and movements are related and are developing at the same time.
- Initial infant movements are associated with crying, sucking and grasping.
- Newborns' motor skills predominantly consist of reflexes, or automatic movements in response to a stimulus.
- Some reflexes last for the entire lifespan, like coughing, sneezing, blinking, and withdrawal from pain.
