The biological approach to children’s cognitive development is well-established, as it seems obvious that learning must be directly related to neurogenesis (growth of new synapses connecting neurons) and neural pruning (‘cutting back’ of synapses no longer needed). But of course this development through neuroplasticity requires not only good nutrition and nurturing to prevent injury, but also social stimulation, so a lot of research has looked at how trauma and deprivation may affect the cognitive development of the child, by delaying or preventing brain development in crucial areas like the hippocampus and amygdala.
The techniques used to study the brain and neuroplasticity topics under the biological approach can be successfully taught using material from the developing as a learner and the influences on social and cognitive development topics within the developmental psychology option. Recommended studies are Chugani’s (1998) PET scans of children from birth to late adolescence; Gotgay et al’s (2004) longitudinal study mapping brain development using MRI scanning; Luby et al’s (2013) research into the effects of poverty on the brain and the mediating effect of caregiving.
More help with planning is coming in the following weeks!
