1.4.1. Symmetrical signs
In symmetrical signs, the dominant hand and the non-dominant hand function as echo-articulators. This means both manual articulators have the same handshape and perform the movement. Regarding the articulation of movements within symmetrical signs, three types have to be differentiated:
- Parallel movement: Both hands perform an identical movement. Examples are the signs help and transfer.
- Mirror-inverted movement: Both hands articulate the same movement but in opposite directions. Both hands act like mirror images. Examples are the signs syntax and music.
- Alternating movement: Both hands perform the same movement but the movement sequence is alternating. Examples are the signs bicycle and communication.
a. help
