History Of Cognitive Psychology 5 Flashcards
Broad category of loosely associated disciplines that include psychology, philosophy, computer science, linguistics, anthropology, neuroscience and cognitive psychology.
Cognitive Science
Explains cognitive processes by studying the anatomy (structure) and physiology (function) of the brain.
Cognitive Neuroscience
The field of cognitive neuroscience expanded around the _______ when neuroscientists started using _________________ on people performing different cognitive functions.
1980s
Imaging Techniques
Human brain damage and its consequences were noted by __________ who wrote that people’s behavior changed after such damage.
Hippocrates
What are some sources on the discovery of brain lesions?
- Gladiators
- War Victims
- Animals
X-ray to look at arteries of the
brain.
Brain abnormalities:
1. Stroke
2. Tumor
Brain Angiography
Multiple X-ray photos with moving X-ray device, making a 3D picture of the brain.
Poor resolution.
Cannot determine structure-function relationships.
CT Scan
A strong magnetic pulse, moves molecules in the brain.
Motion of molecules are picked up
as radio frequencies are reconstructed in 3D images.
Magnetic Resonance Imaging
Increased radio-labeled glucose activity is scanned in the brain while subjects engage in different cognitive processes.
Positron Emission Tomography
What are some features of PET?
- Good spatial resolution
- Poor temporal resolution
- Invasive procedure
Detects changes in blood flow to active areas of the brain.
Provides anatomical and
functional view of the brain.
Functional Magnetic Resonance Imaging
Measures the brain’s electrical activity (potentials) as it corresponds to impinging stimuli (events).
Excellent temporal solution.
Faster then PET or fMRI.
Event-Related Potential
