Phonetics
Left-handed people usually make one-handed signs with their left hand, whereas right-handed people articulate them with their right hand. Could you also call this a variation of pronunciation? Motivate your answer.
This is indeed just a difference in pronunciation/articulation, and thus a phonetic difference. Crucially, this difference does not play a part in the linguistic system (of the sign languages investigated to date), and consequently, it cannot be phonological (there is, for instance, no minimal pair defined by handedness, i.e. a form signed by the right hand having one meaning, and the same form signed by the other ).
