Module 2 - Infant Development Flashcards
Development is…
Multi-directional: losses & gains at every age
Plastic: within person varibility
Fetal:
Affects of environment:
Poverty associated with
-Increased stress
-Fewer but more hostile interactions
-External environmental risks
-Serious developmental risks
Teratogens
Harmful environmental agents that impair prenatal development and lead to birth defects, death or later impairments (emotional, behavioural, intellectual). Can include drugs, parental factors, environmental
Teratogens Risk Factors
- Heredity
- Interaction effects
- Timing
- Environmental interactionsD
Fetal Alcohol spectrum Disorders: ARND (Alcohol-related neurodevelopmental disorder)
From drinking 1-3 alcoholic drinks per day
Fetal Alcohol spectrum Disorders: FAS (Fetal Alcohol Syndrome)
From drinking more than 3 drinks per day or bing drinking in early pregnancy.
The timing of consuming alcohol is relative and the fetus is more vunerable between 3-6 weeks.
Socio-behavioural risk factors.
Infant Brain Development
At birth - baby brain weight 25% of an adult brain weight
2 years - 80% of adult brain weight - Increases due to dendrite growth & myelination
Determinant of brain development
Maturation & Stimulation are borth needed for brain development. Deprivation of stimulation studies done to prove that it is necessary.
Rozenweig 1984 rat experiment
Beckett 2006 Human deperivation studies
Summary of brain developmefant Brain Development
Genes, early environment, interaction between the two and timing of interaction place the developmental pathway that inflences the rest of develoipment
Vision: Face Perception
Eg: Preference for mother’s face and still face enxperiement
Vision: Depth Perception
Ability to judge distance of objects.
Tied to motor development, esoecially crawling.
Eg: The visual cliff
Toddler Imitation
Depends on the motor and cognitive skills necessary to carry out the action to be imitated.
At 15 months, chilkdren are usually mobile and have some hand-eye coordination
