Biological Bases of Behavior Flashcard 4

Front

Which brain imaging technique could be considered invasive? Options: PET scans, MRI scans, CT scans, fMRI scans

Back

PET scans

Front

Which of the following is true about the use of brain imaging techniques in the study of the brain? Options: The scanner is a natural environment, so the results have high ecological validity. An fMRI or MRI cannot be replicated, so these studies are not highly reliable. The emotional state of an individual being scanned can interfere with the quality of the data collected. The colors help researchers to understand exactly what is happening in the brain.

Front

What is a key difference between an MRI and an fMRI?

Back

MRIs show the structure of the brain; fMRIs show the functioning brain.

Front

How do fMRIs measure neural activity in the brain? Options: By tracking glucose levels, By measuring changes in blood flow and oxygen levels, By capturing electrical activity, By detecting radioactive tracers

Back

By measuring changes in blood flow and oxygen levels

Front

Which of the following is a key advantage of using MRI scans? They can measure both structure and function of the brain simultaneously, They are non-invasive and provide high-resolution images, They do not require any special training for psychologists, They are the cheapest form of brain imaging

Back

They are non-invasive and provide high-resolution images

Front

Why is PET scanning considered an invasive technique?

Back

It involves an injection of a radioactive tracer

Front

Which of the following is not a limitation of the use of fMRI scans in psychological research? Options: They are expensive and create artificial environments, The interpretation of the scan is open to researcher bias, External factors can influence brain activity, leading to low internal validity.

Back

An fMRI or MRI cannot be replicated, so these studies are not highly reliable.

Front

What does the high cost of brain imaging techniques typically result in for research studies?

Back

Samples with low potential for generalizability

Front

What is the key difference between an MRI and an fMRI?

Back

MRIs show the structure of the brain; fMRIs show the functioning brain.

Front

What does Electroencephalography do?

Back

Examines neurons to track electrical signals in the brain
