Signs might be articulated with smaller movements (movement reduction) or larger movements (movement extension) compared to their citation form. Movement reduction can be observed while using a smaller signing space without making very detectable movements, as for instance while whispering. On the other hand, movement extension can be expressed via the usage of a larger signing space, as for expressing strong emotions. The same can be observed in situations when people are willing to be more detectable, as for instance while shouting [Phonology 3.4.2]. In these phonological processes, the use of different joints can be observed as well [Phonology 3.1.3.2].
