AbstractConcreteness ratings are presented for 37,058 English words and 2,896 two-word expressions (such as "zebra crossing" and "zoom in"), obtained from over four thousand participants by means of a norming study using internet crowdsourcing for data collection. Although the instructions stressed that the assessment of word concreteness would be based on experiences involving all senses and motor responses, a comparison with the existing concreteness norms indicates that participants, as before, largely focused on visual and haptic experiences. The reported dataset is a subset of a comprehensive list of English lemmas and contains all lemmas known by at least 85% of the raters. It can be used in future research as a reference list of generally known English lemmas.
Concreteness ratings for 40 thousand English word lemmasConcreteness evaluates the degree to which the concept denoted by a word refers to a perceptible entity. The variable came to the foreground in Paivio's dual-coding theory (Paivio, 1971(Paivio, , 2013. According to this theory, concrete words are easier to remember than abstract words, because they activate perceptual memory codes in addition to verbal codes.Schwanenflugel, Harnishfeger, and Stowe (1988) presented an alternative context availability theory, according to which concrete words are easier to process because they are related to strongly supporting memory contexts, whereas abstract words are not, as can be demonstrated by asking people how easy it is to think of a context in which the word can be used.
