RE: [tips] Why Do Neuroscientists Hate Left-handers?

Yes, that was the rationale for controlling for sinistrality. In fact, I read a 
few of Hellige’s papers, which were required reading in one of my grad courses.

Here is an old video of the WADA test, 
https://www.youtube.com/watch?v=SBKc_ncPzOo, which is the technique I think you 
are referring to.

I did laterality research for my dissertation work - my mentor was Joe Hellige 
who did a lot of work in laterality. (Ok this was late 80's/early 90's).

We excluded lefties for these reasons: Righties are pretty much lateralized 
with language right, VS left; and this comes from studies during neurosurgery 
in which surgeons would isolate one hemisphere from the other to map out 
language areas before going in removing tumors, etc. to try to minimize damage 
to language areas. They basically inject each carotid with a solution that 
would paralyze functions in the opposite hemisphere. When it comes to lefties, 
however, language was unpredictable. Sometimes it was all in the right, 
sometimes all in the left and quite bilateral. Since we were primarily 
interested in dual tasks that combined language with distal musculature (finger 
tip tapping) we wanted to be sure to maximize the probability that any shared 
or unshared resources would be hemisphere specific. Hence the need to exclude 
lefties because we could not do  the invasive carotid artery injections ;-) And 
this may be at least basis for neuro studies excluding the 
lefties--unpredictable lateral distribution of functions.

Here's a factoid to toss out when reviewing the problems and
​
limitation of contemporary neuroscience:

Left-handers are not used in neuroscience research.

I had assumed that they had been included and may
​
have been analyzed separately from right handers
(and people who are ambidextrous) in the same
​
way that monolinguals and bilinguals are analyzed
separately.

For more on this point, here is an interview with

leftie Paul Silva on HuffPo:

And don't forget that August 13 is International Left-Handers
Day.

I recall reading studies on laterality which would often exclude subjects with 
any degree of personal sinistrality  (e.g., being left legged, or left eared, 
and/or perhaps performing certain tasks with the left hand -writing with the 
right hand but throwing a ball with the left) or familial sinistrality.
