The Neuroconstructivist View1
-Biological processes and environmental conditions influence the brain’s development
-the brain has plasticity and is context dependent
-development of the brain is closely linked with the child’s cognitive development
Frontal Lobe
involved in voluntary movement, thinking, personality, and intentionality or purpose
Occipital Lobe
function in vision
Temporal Lobe
facilitate hearing, language processing and memory
Parietal Lobe
help to register spatial location direct attention and maintain motor control
Amygdala

Myelination
-the process of encasing axons wit a myelin sheath
-begins prenatally and continues after birth
-myelination of visual pathways occurs rapidly after birth - completed in first 6 months
-auditory myelination is not complete until 4 or 5 years
Corpus Callosum
fibers that connect the brain’s hemispheres
-thicken in adolescence -improving ability to process information
