Please print out and rehearse your parts:
Kristin: This is our presentation for our assigned Essential Question for Unit 2 : The life Span.
Created by Myself, Ana Ramirez, Alex Garcia, Angelina Cano, and Andrew Reynoso.
*Slide 2*
Kristin: We were assigned the second Essential Question: What research techniques are used to gather data about human development.
As we know, to study development in humans is to research many aspects of their behavior as they mature through life. Infancy, Childhood, Adolescence, early adulthood, midlife, and the "golden" years.
*Slide 3*
Alex: Some research techniques include using observation. Longitudinal and Cross sectional vary in where Longitudinal take much time to research and also Cross Sectional is very quick and has a variance of peoples development over all in general.
*Slide 4*
Alex: So here are some Pro's and Con's of both. *List off the slide, you will see when we present, nothing to big that you have to remember immediately.*
*Slide 5*
Angelina: There are different and quicker ways to get information. But they may not be Accurate. Since Poll's have no connection or commitment to be accurate. The same thing may apply to a survey but, there is more likely that there will be a interference in the data based on the givers body language or facial reaction to a persons answer to a question. and Naturalistic observation should be random and over a small period of time... other wise that could be considered stalking.
*Slide 6*
Ana: In using observations for work when it involves one or few persons then they must be regarded under false names. Also you need to get permission from them or their guardian when it comes to long periods of study.
*Slide 7*
Andrew: Now how can you study infants? They don't really talk, they cant tell you whether they want something or whether they understand. They don't know how to write and they don't know how to sign language... but they can show emotions. When you take away a child's toy... its likely to cry or completely forget about it. This lets researchers know whether the infant has developed some kind of spacial permanency.
*Slide 8*
Kristin: Now there are some relations to what the neurological development and behavior stages in persons. Using EEG, CAT, PET, MRI, and MEG machines we can learn about how the brain develops physically.
*Slide 9*
Angelina: To use EEG then you put a cap ontop of the patients head that connects to the machine that will recieve the impulses in the brain and display them on galvanometers, that look display the information similar to that of how they measure quakes in the earth.
Andrew: CAT uses cross sections of 2 images to produce a 3 dimensional image of the brain and disturbances in blood flow within the brain.
Alex: Using Trace substances they can use PET to trace the activity of the brain, of where the glucose would be absorbed by active brain cells
*Slide 10*
Ana: By using MRI you can measure the brain activity with out trace substances being injected and simply measure the reaction energy that is not canceled out during the MRI's margnetic field.
Kristin: MEG is a machine that measures the faint magnetic field of the brain. This is the most accurate way of measure the brains nerve activity to the smallest millisecond but it is also the most expensive
*Slide 11*
Kristin: Now you may be asking how the development of the neurological pathways and brain have anything to do with behavior or development as humans as a person. How this is important to study this.
Well there is a correlation: Children and Infants seem to have more ability to learn and react, in Adolescence we are starting to reach more neurological development. Where we react more and also more timely than when we were older. In the elder years our neurological development seems to decline and as a result we would lose some of our senses and our ability to react if they were not developed enough to keep this ability strong through maturity.
Studying these developments can forward the understanding between aging physically and aging mentally. That our physical development is connected to our emotional development
*Slide 12*
Kristin: Thank you for listening and if you have any more questions be free to ask me. Thank you!
