Shown here is an example of a stimulus used by Kosslyn and colleagues (1989)in experiments asking participants to judge whether the dot should be categorized as being above or below the line.It was found that performance on the task was faster when the stimulus was presented in the right visual field.Although one interpretation may be that the left hemisphere is specialized for categorical processing,an alternative explanation is that this task

A)may require the analysis of relatively high-spatial-frequency information.
B)is easy,and the left hemisphere is specialized to complete relatively easy cognitive tasks.
C)selectively involves the processing of global structure.

The finding that the stimulus presented in the right visual field resulted in faster performance suggests that the left hemisphere, which processes information from the right visual field, may have an advantage on this task. However, this advantage could be due to the fact that the task requires the analysis of relatively high-spatial-frequency information, which may be processed more efficiently by the left hemisphere, rather than categorical processing specifically. Therefore, the best choice is A, which describes the potential role of spatial frequency in the left hemisphere advantage on this task.
