This paper presents norms for concreteness and emotional valence of 200 monosyllabic and 199 three-syllabic nouns. Both sets of words were comparable in lexical familiarity. Each word was rated for both characteristics by at least 145 raters. Test-retest and inter-rater reliability proved high for both concreteness and emotional valence ratings. The norms also proved reliable in comparison to three other studies, and they proved effective in two experiments; one with concreteness as an independent variable and one with emotional valence as an independent variable. The nouns, their mean rating and standard deviation arc presented in the appendices, together with two measures of their frequency of occurrence.
