About the questionnaire, I originally found it on Naresh's blog, and thought I'd give it a spin. Here are the results:
Your Brain Usage Profile:
Auditory : 38%
Visual : 61%
Left : 52%
Right : 47%
Nirbheek, you exhibit an even balance between left- and right- hemisphere dominance and a slight preference for visual over auditory processing. With a score this balanced, it is likely that you would have slightly different results each time you complete this self-assessment quiz.
You are a well-rounded person, distinctly individualistic and artistic, an active and multidimensional learner. At the same time, you are logical and disciplined, can operate well within an organization, and are sensitive towards others without losing objectivity. You are organized and goal-directed. Although a "thinking" individual, you "take in" entire situations readily and can act on intuition.
You sometimes tend to vacillate in your learning styles. Learning might take you longer than someone of equal intellect, but you will tend to be more thorough and retain the material longer than those other individuals. You will alternate between logic and impulse. This vacillation will not normally be intentional or deliberate, so you may experience anxiety in situations where you are not certain which aspect of yourself will be called on.
With a slight preference for visual processing, you tend to be encompassing in your perceptions, process along multidimensional paths and be active in your attacking of situations or learning.
Overall, you should feel content with your life and yourself. You are, perhaps, a little too critical of yourself -- and of others -- while maintaining an "openness" which tempers that tendency. Indecisiveness is a problem and your creativity may not be in keeping with your potential. Being a pragmatist, you downplay this aspect of yourself and focus on the more immediate, obvious and the more functional
So, they claim to have deduced the above
Hence, IMHO, an utter load of crap.
