Examining the role of word identification in synonymy judgment

This paper examines the role of word identification in semantic judgment tasks. We argue that word-identification processes can substantially alter the functional properties of semantic judgment tasks. We investigate this empirically by examining the effects of semantic relatedness and relatedness proportion on synonymy judgments of non-synonym pairs. The results demonstrate that semantic relatedness slows synonymy judgments for non-synonym pairs when the relatedness proportion is low, but speeds them when the relatedness proportion is high. The former effect is a replication of traditional findings, while the latter effect reverses these findings. We explain these results by hypothesizing that increasing the relatedness proportion increases the beneficial effects of semantic relatedness in word identification, and this produces the reversal of traditional findings. We close by emphasizing that models of semantic judgment tasks can become more comprehensive by focusing on word identification.
