Effect of Handedness on Intelligence Level of Students

Handedness is the natural or biological preference for using one hand more than the other in performing special tasks depending on which hemisphere is dominant for the task (Rice, 1998). People are said to be right handed if they use right hand most of the time, and left handed if they prefer left hand. People are referred to be ambidextrous, if they use both hands equally well and approximatel...

Manual asymmetry and handedness.

Volumetric measurements show that right-handed individuals have larger right hands than left hands. In contrast, the hands of left-handers are much more nearly symmetrical. Based on what is known about trophic interactions between neurons and targets, these findings predict a corresponding asymmetry of the relevant parts of the sensorimotor system in right-handers. The lack of an opposite-hand ...

Handedness and earnings.

We examine whether handedness is related to performance in the labour market and, in particular, to earnings. We find a significant wage effect for left-handed men with high levels of education. This positive wage effect is strongest among those who have lower than average earnings relative to those of similar high education. This effect is not found among women.
