WebApr 5, 2024 · A chiral display is often perceived subconsciously and lets us know something is odd. When we see facial chirality as a result of multiple emotions, this lack of symmetry should make us more alert as to what is the cause for this behavior. Is there a substantive issue that is in conflict or is being suppressed? WebThe chirality of an object is related to its symmetry, and to this end it is useful to recognize certain symmetry elements that may be associated with a given object. A symmetry element is a plane, a line or a point in or through an object, about which a rotation or reflection leaves the object in an orientation indistinguishable from the original.
