Imageability and body-object interaction ratings for 599 multisyllabic nouns

We collected imageability and body-object interaction (BOI) ratings for 599 multisyllabic nouns. We then examined the effects of these variables on a subset of these items in picture-naming, word-naming, lexical decision, and semantic categorization. Picture-naming latencies were taken from the International Picture-Naming Project database (Szekely, Jacobsen, D'Amico, Devescovi, Andonova, Herron, et al. Journal of Memory and Language, 51, 247-250, 2004), word-naming and lexical decision latencies were taken from the English Lexicon Project database (Balota, Yap, Cortese, Hutchison, Kessler, Loftis, et al. Behavior Research Methods, 39, 445-459, 2007), and we collected semantic categorization latencies. Results from hierarchical multiple regression analyses showed that imageability and BOI separately accounted for unique latency variability in each task, even with several other predictor variables (e.g., print frequency, number of syllables and morphemes, age of acquisition) entered first in the analyses. These ratings should be useful to researchers interested in manipulating or controlling for the effects of imageability and BOI for multisyllabic stimuli in lexical and semantic tasks.
