Overview People Teaching Research Icon recognition (4/4) • 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
