(cid:499) usually can notice this jnd then an additional 500g. Won(cid:495)t be able to notice the jnd like in detectable 50% of the time. Law: weber(cid:495)s law, as you increase the intensity of stimulation (eg. weight) you also need to increase the magnitude of change, eg. need 5kg weight added on top of 50kg vs 500g to notice the difference.
