What are the physical developments in childhood?
– Reflexes
•Some persist throughout life (coughing, blinking, yawning)
•Some weaken or disappear by 7 months (grasping, sucking, stepping (if you hold a baby up the feet will do a stepping motion), startle)
– motor & perceptual develop over time
• Perceptual development (connections between eyes/brain, and processing of visual stimuli is not fully developed) is tied to motor development – in that it requires adequate perception to be able to coordinate movement.
• As our brain (wiring) & perceptual skills improve, our motor abilities also improve
• Early motor development also depends in part on physical growth (maturation -gradual expression of genes) and infants’ ongoing exploration of the world
– Brain development
• At birth, the brain has minimal connections between neurons (dendrites are underdeveloped), the myelin encasing the neurons in the brain is not yet fully formed, and there are extra neurons
• Through the process of development, the dendrites grow to facilitate the connections between the neurons.
•The myelin develops to facilitate neural communication.
•The unused neurons die
What are developmental norms?
How do cultural variations affect developmental norms?
What is temperament?
refers to characteristic mood, activity level, and emotional reactivity
What is the difference between longitudinal design and cross-sectional design?
What are cohort effects?
–Cohort effects occur when differences between age groups are due to the groups growing up in different time periods
