1.Evaluate the significance of evolutionary concepts and principles for understanding human behavior.
The theory of Evolution helps us understand how humans have changed over time and why. The study of variation is very important in the understanding of evolution. Variations are modifications between an individual that help guide functioning that can come from an outside resource. This is a factor that leads the differentiation between each distinct person. Another theory of variation is Lamarckism. Lamarckism is the belief that learned behaviors are passed from one generation to the next. Each theory was challenged from one scientist to psychologist to theorist to pose question of controversy.
2.Identify potential genetic contributions to Raul Salazar’s difficulties in the Salazar case.
Raul’s fathers’ side of the family has a history of alcoholism, and bad temper. And on the other side, Raul’s mother has a background of depression and anxiousness. These can genetically contribute to addiction, melancholy and anxiety. In early childhood these problems should be addressed so the child does not pick up on the behaviors passed from parents.
3. Describe the four stages in the development of neurons.
The first stage of neuron development is Proliferation. This is where a rapid reproduction of new cells occurs. After many cells have been reproduced, they then begin to Migrate which is the second stage. This is where each cell makes the grand voyage from the inside of the brain to the outer layers. Once the cells have found a home, they stay in the spot to start their chosen role. Differentiation is the third stage of neuron development. This is where the cells start forming axons and dendrites. Ultimately the cell changes from a basic cell type to a specialized cell type. The final stage of neuron development is called Myelination. Here is where the axon is protected by cases of myelin. The fat insulation is the cushion that lets signals travel 100 times faster than an unprotected axon. (Ashford, pp. 80-81)
4. Identify potential threats to the brain development of Raul Salazar associated with information described in the chapter’s case scenario.
Raul spent much time banging his head off of hard objects to get him to fall asleep or calm down. There are four lobes of the brain that apply and develop specific skills, if damaged there will be a disruption or block against development. The frontal lobe is the largest front most part of the brain. This is where the activity of body movements, thoughts, feelings and decision making develops. Broca’s area is a small area within the frontal lobe that is a huge part of speech production. If Raul caused damage to this part of the brain while causing harm to his skull, he is going to have some difficulties processing these activities.
5. Identify and describe measures that can be used by researchers and practitioners in assessing physical resilience.
Physical resilience is the body’s ability to adjust to arising encounters and recover efficiently. Researchers have found biological factors that indicate the body’s capacity for responding to variation. The allostatic load is the amount of wear and tear of the body due to chronic activity/under activity. People with lower allostatic load are typically socially and physically healthier.
