Just as articulation pauses of various sorts can be found in
natural speech, certain
held postures exist on the gestural level. There is a variety of such postures that
can be observed, frequently varying from speaker to speaker.
Possible examples of postures for a speaker in a seated
position can be folding their hands and resting them on their
lap or, if sitting in an arm chair, placing their forearm(s) and/or
hand(s) on one or both armrests.
Held postures might appear to be comparable to static gestures
in that they do not involve movement; however, they need to be
carefully distinguished from static gestures in that postures are not
perceived as conveying meaning unless understood as part of a
speaker's coincident emotive body language.
