• Chez les humains, le type d’icones non identifiées varie selon le niveau de connaissances – les novices identifient moins les icones simili
– sans info-bulle, les experts identifient moins les icones figuratives
• Pour LSA, le profil des icones non identifiées est proche de celui des experts– les icones les moins identifiées sont des icones figuratives et
l’info-bulle a un effet positif important
