问题     Does the evidence that the left and right sides of the brain differ somewhat in function have implications for personality differences? There is research indicating that the right hemisphere is linked to negative emotions, to spatial or imagery processing, and to thinking of pure melodies, while the left hemisphere is linked to verbal and mathematical thought and positive emotions. Is it possible that each half of the brain reflects two basic but different dimensions of human capacity? Are some personality differences that involve consistent styles of information processing of reflective thought correlated with a greater activation of the left and right hemispheres?
    Adults who differ in their initial encoding styles also demonstrate brain wave patterns or eye movement differences that suggest they " favor" one or another hemisphere of the brain during reflective thought. An approach to studying such differences has emerged by examining the direction in which people shift their eyes when trying to reflect on a question or to recall information. Anatomically(从解剖学上来说)the neural pathway from the left eye goes to the right hemisphere of the brain and from the right eye to the left hemisphere. Since our eyes normally shift together, it has been shown that the stimulation of the right brain hemisphere leads to a shift of the eyes to the left and, correspondingly, left hemisphere stimulation shifts the eyes to the right.
    Studies of persons who show consistent left-or-right-eye shifts when engaged in reflective thought do offer some support for the views. Right shifters(that is, those whose left brain are most active)are more analytic in perceptual performance and score higher on measures of verbal concept formation, mathematics scores, and measures of mathematical, scientific, or theoretical interests. Left shifters are more imagery oriented, more inclined to daydream, more creative and aesthetically oriented. Left and right shifters even differ in where they prefer to sit in college lecture halls, with left shifters sitting on the right side and right shifters to the left of the center.
The idea that the left and right sides of the brain differ somewhat in function______.
选项 A、is proved to be unfounded
B、has consistent evidence to support itself
C、is proved to be true in some cases
D、lacks biological evidence
答案B
