Explain synaptogenesis and synaptic pruning.
1. Professor Carver discussed the lifespan perspective and biological elements of brain development.
1. Explain synaptogenesis and synaptic pruning.
According to lecture the synaptogenesis is formation of synapses between neurons. Synaptic pruning means in the brain, it is a natural process that happen in the early childhood to the adulthood. During the synaptic pruning it might remove extra synapses
2. Define the three types of neuroplasticity.
I don’t I am referring to right one. Three type of neuroplasticity is recovery of function. Second change because of learning. Last on expected experience effects.
3. What are two principles of lifespan perspective discussed in terms of brain development? (J)
According to lecture, The two principle can be 1) Change is continuous, there is no fix stage at brain and cognition 2) Differences can be found along a continuum
2. Dr. Carver mentioned several ways that the brain and development can be understood in terms of signaling.
1. How does signaling relate to the definition of developmental change that we discussed early in the course?
Signal come from sensory organ. It is eye, nose, ears, skin tongue and It will help us to see, smell, feel or taste. Human use this to received the information. This is help us reach to developmental milestones
2. What is an example of a signal within the body that guides the development of a neuron?
I think neuron process the incoming information. I am not sure the equestion try to ask but I guess it is talk about the 3 phrases in the life of a neurons which is proliferation, migration and differentiation. Proliferation is generation of neutron, migration is movement of neuron to target brain region, last is differentiation is connected to the cells
3. How does the role of signals help us understand the role of the environment in brain development?
The role of signals that in the environment help the brain development. For example teenager brain are still changing to adapt to a social and complex world.
3. Dr. Walker discussed Piaget’s contribution to cognitive development.
1. What did Dr. Walker claim were the two fundamental aspects of Piaget’s theory?
Two fundamental aspects will be development happen in stage and learning is a constructive process.
2. One aspect has been challenged and one has endured. Which aspect of his theory has endured and why?
Learning is constructive process is enduring because children are like little science and they keep test out until they get the answer which is like scientist. Which mean children are active learning.
4. Dr. Walker illustrated the role of competence and performance in researching cognitive development among infants.
1. Explain the difference between competence and performance.
Competence is knowledge and performance are require other abilities
2. How does failure to account for this difference lead to an inaccurate assessment of a child’s understanding of object permanence?
Children does not have ability to perform accuracy because they cannot speak.
3. What methods were used to challenge Piaget’s belief that object permanence develops at 9 months?
Stare and look at the picture until they are boring will be method that challenge Paget’s belief
5. What evidence did Dr. Walker provide for the hypothesis that a child is a little scientist?
For example, the children observe, and they will test out hypothesis they will accept and reject the hypothesis. For example, what to make the lamp light. The children will try to find the button to let the light the lamp. They will test until they success.
