on the cognitive architecture pertaining speech (speechreading & alphabetical reading) and sign (SW representation & processing: reading & spelling)

Dear Vallerie,
Thank you for your great remarks. You are right: because of the many
regional variations and dialects existing in Libras, illustrations (both
meaning illustrations and specially sign form illustrations) help to
establish consensus about the relationships between the precise sign form
that is illustrated and described, and its respective SW rendition. So the
purpose of illustrations is twofold: helping learn Libras & SW,
and stressing just how transparent SW is as a sign writing system. Thank you
for understanding.
Best regards,
