Types of study designs
This type of study design can include surveys, direct observation, or case studies
What is a descriptive research design?
This type of test directly detects electrical activity in the brain
What is an EEG?
Studying structures — such as human hands and elephant trunks — that have similar functions but are structurally different
What is analogy?
Through a case study, it was found that damage to the left inferior frontal region of the brain leads to severely impaired language production, slow, effortful speech, poor articulation, and relatively spared comprehension
What is Broca’s Aphasia?
This method of research would best answer the question: what percent of people in a given population suffer from depression?
What is a survey?
This type of study design looks for a relationship between 2 or more variables
What is a correlational study?
A type of test that is able to detect the timing of the signal very well
What is good temporal resolution?
Once this is identified between humans and another species, the species can be used to study the structure in humans
What is homology?
Through a case study, it was found that damage to the left superior temporal gyrus leads to poor language comprehension and difficulty speaking in coherent sentences
What is Wernicke’s Aphasia?
A type of test that is able to detect where the signal is coming from
What is good spatial resolution?
This type of study design is generally not performed on humans
What are lesion studies?
This type of test uses a powerful magnet and looks at the differences in proton spin in order to differentiate tissues in the body
What is an MRI?
Understanding this will help you determine which animals are the best candidates for animal models
What is evolutionary biology?
Jane got into a car accident and damaged this part of her brain. It now takes her an excessive amount of time to say her name, age, and other basic information.
What is Broca’s area?
This type of test uses a proxy measure, known as the BOLD signal, to indirectly look at brain function
What is an fMRI?
This type of research design focuses on assessing and/or quantifying the relationship between factors
What is an analytic study?
The substance most commonly used as a radio labeled ligand in a PET scan
What is glucose?
When there is a resemblance between features among animals that do NOT share a common ancestor.
What is homoplasy?
One of the most famous case studies, revealed how damage to the frontal lobe can affect personality, disposition and mood
Who is Phineas Gage?
The similarity between the fins on a fish and a dolphin
What is an example of homoplasy?
