Concept‐maps, logic and the cerebral hemispheres

Finds a statistically significant relation between top‐down concept‐mapping and the right cerebral hemisphere, and between bottom‐up concept‐mapping and the right hemisphere. Correlates scores on concept‐mapping with scores on hemispheric tests, and compares the scores of the subjects on hemispheric tests with the preferable style of concept‐mapping. Concludes that top‐down concept‐mapping, the right hemisphere, and Frege’s logic are mutually related. Similarly, bottom‐up concept‐mapping, the left hemisphere, and Russell’s logic are mutually related.
