The present study reviews the role of imageability in the lexical–semantic processing of the hypernym/ hyponym relation. Two research questions are discussed. The first question examines if an average level of hyponym imageability is higher than an average level of hypernym imageability. The second question explores if word pairs connected by a semantic relation between hyponym and hypernym differ in mental processing speed depending on the level of word imageability of words that make a pair. These two research questions lead to an additional question: Is the speed of lexical–semantic processing of word pairs in which both words are highly imageable higher than in word pairs of mixed or low word imageability level? The obtained results are interpreted in line with the dual coding theory and the theory of lexical access, along with the parallel activation model in the componential analysis of meaning.
