PSYD33- lec 3
Neuropsychologist looks at especially cognitive and cortical areas of the brain
Cognitive tests are not IQ tests.
It breaks up the tests and tests smaller bits of the brain functioning, often testing the damage occurred n
the brain result of stress, toxins, external damage or internal like strokes
Cortex: outer parto f the bran, two sides of bran. Left hemisphere is more imp in males for lang, thinking
in words, math. Females have better sharing between the two hemispheres
Reading and writing depend on the parietal lobe because they require a spatial analyzer
Homunculus is in the parietal lobe as well as the outer spatial map
One homunculus in both lobes. The right parietal map of external space is superior to the left one.
In the left lobe it encodes only the space to the right of the midline in the body. That is the hemispace
The right parietal lobe has representations for both the right and left side of the lobe.
The knowledge of spatial locations is dependent on which side of space and dependent on which way
you are oriented
The parietal lobe is giving the information from the occipital lobe a shape.
In terms of vision, we can also see motion. In order to recognize an object there is a pathway in the
occipital lobe that comes in through the retina, then it is sent to the temporal lobe to essentially
recognize it as an object or a name. or it goes upto the parietal lobe for thte spatial map. It is the dorsal
stream of the visual system. Motion is perceived through the dorsal stream, the object
