have a good knowledge about all my teachings so far
Answer: Functional magnetic resonance imaging (fMRI)
Explanation: Whether in the right or left hemisphere, increased brain activity associated with increased blood flow is measured by functional magnetic resonance imaging (fMRI) or functional MRI. This technique is based on the fact that the activation of neurons in the brain is related to blood flow also in the brain. When the brain is strained by some perceptual task, that is, the part of the brain responsible for some perceptual function, then the blood flow through that part of the brain increases. This again means a change in the magnetic image being recorded, due to the fact that the blood carries certain charges and with their increase that can be recorded, and due to the activity of the part of the brain, the increased activity of neurons can be measured.
Answer: Correlational study is to refer the relationship between two variables.
Explanation:
Correlational study is perform there are three types (1) positive correlational (2)negative correlational (3) no correlational.
- Positive correlational is they contain the variables increase and decrease at same time and positive correlational is indicates +1.00.
- Negative correlational is they amount of the one variable increase and decrease and negative correlational is indicates -1.00.
- No correlational is they no relation between the two variables.
- Correlational study is perform the type of research in psychology as like the medicine, its also used it researches to perform on the experiment.
- Correlational study is the relationship between they demonstrate variables and prove cannot change variable,they perform cause and effect relation.
- There are three types correlational research (1)naturalistic (2) survey method (3) archival research.
- Naturalistic :- is that method involve recording and observing the variables to the without interface, in this research view variables in natural settings.
- Survey method is perform to the involve random sample of complete survey to the variables interest, they research perform cheap, easy and fast.
- Archival research:- this research conduct to the long and reviewing historical case study, this research cannot change participant behavior.
