Chapter 3 Flashcards
Development
Study of change.
Nature vs. Nurture
Nature: Genetic code
Nurture: How ones environment effects them.
Continuity & Stages
Continuity: Develops over time (vocabulary).
Stages: Happens automatically (crawling to walking).
Stability & Change
Understanding normal stability and changes can help us understand what is not normal (If a child is not walking at 16 months there is too much stability in crawling).
Conception
About 250 million sperm ejected, it takes 18 to get the job done, but only 1 is going to fertilize the egg.
Prenatal Development
Zygote: fertilized egg that replicates genetic code
Embryo: first couple weeks
Fetus: by 9 weeks
Critical Period
A time in which the developing human must experience something, if they don’t they won’t be able to develop certain skills.
Teratogens
Anything that can adversely affect child development (alcohol, radiation exposure, viruses).
Neurogenesis & Synaptogenesis
Neurogenesis: the process of creating new neurons.
Synaptogenesis: the process of forming connections between nerves.
Rapid Growth & Pruning
At 7 years old, the brain is overcrowded with information (rapid growth), to make room, the brain goes through the process of pruning to make the brain more refined and effective.
Experience expectant & Experience dependent
Expectant: Normal development (walking, talking)
Dependent: Unique experiences that contribute to brain growth (children playing with an abacus)
Enrichment
How much stimulation an infant gets, adds to dependent experience.
Preterm births (preemies)
Preterm birth: early birth
SGA: Small for gestational age
Jean Piaget’s Theory
Learning is like climbing a ladder, one must have a stable hold on the previous rung before moving onto the next.
Piaget’s Stages
- Sensorimotor (0-2 years): Take in the world through senses and actions.
- Preoperational (until 6-7 years): Represent things with words and images, pretend play, but not understanding models.
- Concrete operational (7 years): Grasp more complex concepts like math
- Formal operational (12 years): Abstract thinking. If this then that. Control emotions.
