a person's learning style greatly influences the way he participates in a group project....you might want to look at the works of Edward de Bono, and his "Six Thinking Hats"....to help identify a student's learning style, I used the basic premise as a class activity... by letting my students choose which colored folder they wanted for their class notes... the color matched their self described personalities pretty well

...also you might look at the Gregoric Delineative, but it has lost some favor...the correlation between learning styles and brain dominance with the students was an on going project for me, especially with my student athletes and their reaction times.. I had very bright science students that had difficulty doing sequential problem solving steps, particularly factor-label Stoichiometric sequences ... to streamline the terminology, I standardized two... global and concrete sequential, and attempted to help the students learn their particular style, to help them better navigate my class (I'm concrete sequential, and taught that way)

what shook out was a correlation between brain dominance and reaction times...opposite side of brain dominates eg. right hemisphere controls left side of body

by dropping a ruler, and allowing them to catch it with, and without warning eg. 3, 2, 1, drop....they could convert the distance to a time (d = 1/2 att)

left handed ... close to .10 sec or less

right handed, dominant left eye .... < .14sec

right handed, dominant right eye, when fingers interlaced and thumbs overlapped end up with left thumb on top >.15

right handed, dominant right eye, right thumb on top >.20sec

the quickest tended to be very global, and had the hardest time doing sequential tasks...tended to like history, literature
the slowest tended to like math and science

always maintained we put the wrong person in the cockpit of a fighter .... really needed the quy/girl with the quickest reaction time not an engineer...
