Handedness with Regard to Kinematic Principlesof Nasta liqScript

Hand، moving the pen on paper، is a vital tool in writing and calligraphy. The counter position of hands and differences between the right-handedness and left-handednesslead to the question of existence and qualities of a reciprocal or one-sided relationship between kinematicprofiles of handedness and writing. What make this question more significantarethe scattered and varied opinions on left-handers’ issues in writing and calligraphy thatexpress different beliefs about the proportionatenessof the writing direction tohandedness. Therefore to study the kinematic profiles of handedness and Nasta’liqscript and their relationship،this paper addresses two terms of handedness kinesiology and Nasta’liq kinesiology. In Nasta’liq kinesiology the straight directions (horizontal، vertical and diagonal) are explored. Handedness kinesiology examines course and direction of both curved and straight lines (horizontal، vertical and diagonal) by left handers and right-handers. The results indicate that the writing habits amongst left-handers and righthanders do not have considerable effects on the choices of direction and course while writing. On one hand the results of right-handedness kinesiology and Nasta’liqscript are parallel; so that the predominant course and directions in Nasta’liq are in accord with the predominant directions taken in writing by right-handers. The research method is descriptive-analytic using published material and field research.
