If I remember correctly about this it's what I wrote below........

What is non-invasive in psychology...........
denoting procedures or tests that do not require puncture or incision of the skin or insertion of an instrument or device into the body for diagnosis or treatment.


What does invasive mean in psychology..........
denoting procedures or tests that require puncture or incision of the skin or insertion of an instrument or foreign material into the body, or to able to spread from one tissue to another, or having the capacity to spread, as in the case of an infection or a malignant tumor.



What is non-invasive and invasive..............
the major difference between invasive and non-invasive tests is that invasive tests are done by cutting or entering a body part using medical instruments, whereas non-invasive tests do not require breaking the skin or entering the body. Non-invasive tests include deep palpation, x-rays, and checking blood pressure.

These 2 definitions are related to like bran scans like fMRI, EEG... It uses invasive and it just confuses me

fMRIs and EEGs are not invasive. Something like deep brain stimulation would be invasive.

one involves sticking something inside the brain (invasive), the other doesn't (non-invasive).

Sticking something as in?

What do these definitions got to do with brain scans?

I'm really sorry, I feel like i am annoying u so much. I just want to be able to understand it

Best thing for you to do is research this further and you'll soon understand things better,



What is fMRI psychology.....
Functional magnetic resonance imaging or functional MRI (fMRI) measures brain activity by detecting changes associated with blood flow.
This technique relies on the fact that cerebral blood flow and neuronal activation are coupled. When an area of the brain is in use, blood flow to that region also increases.



How do EEGS work psychology...
An electroencephalogram (EEG) is a test that detects electrical activity in your brain using small, metal discs (electrodes) attached to your scalp. Your brain cells communicate via electrical impulses and are active all the time, even when you're asleep. This activity shows up as wavy lines on an EEG recording

like the actual definition. it has words i've never come across before and yes ik when ur learning something new u always learn new things. I keep trying to simplify this defnition so i can use to say why fMRI, EEG, ERP and all are non-invasive

Because they don't involve sticking anything inside a brain. If someone was going to investigate brain function by sticking electrodes inside someone's brain, that would be invasive.

Implantation, e.g. implantation of a neural implant
