As researchers explore the complexity of memory and language hierarchies, the need to expand normed stimulus databases is growing. Therefore, we present 1,808 words, paired with their features and concept-concept information, that were collected using previously established norming methods (McRae, Cree, Seidenberg, {\&} McNorgan Behavior Research Methods 37:547-559, 2005). This database supplements existing stimuli and complements the Semantic Priming Project (Hutchison, Balota, Cortese, Neely, Niemeyer, Bengson, {\&} Cohen-Shikora 2010). The data set includes many types of words (including nouns, verbs, adjectives, etc.), expanding on previous collections of nouns and verbs (Vinson {\&} Vigliocco Journal of Neurolinguistics 15:317-351, 2008). We describe the relation between our and other semantic norms, as well as giving a short review of word-pair norms. The stimuli are provided in conjunction with a searchable Web portal that allows researchers to create a set of experimental stimuli without prior programming knowledge. When researchers use this new database in tandem with previous norming efforts, precise stimuli sets can be created for future research endeavors.
Instructions This experiment is part of an investigation into how people read words for meaning. To help us conduct this work, we need information on what people know about different things in the world. On the following pages, there are words that each denote a concept, with each being followed by a blank space. Please fill in as many properties of the concept that you can think of to which the word refers. Examples of different types of properties would be: physical properties, such as internal and external parts, and how it looks, sounds, smells, feels, or tastes; functional properties, such as what it is used for; where, when and by whom it is used; things that the concept is related to, such as the category that it belongs in; and other facts, such as how it behaves, or where it comes from. Please note that even though many of the words can be thought of as something other than a noun (e.g., "camp" can refer to the place where your tent is pitched, or the action of camping), all words on the following pages are meant to be considered as nouns only (e.g., "camp" the place). Here are some examples: duck: is a bird, is an animal, waddles, flies, migrates, lays eggs, quacks, swims, has wings, has a beak, has webbed feet, has feathers, lives in ponds, lives in water, hunted by people, is edible cucumber: is a vegetable, has green skin, has a white inside, has seeds, is cylindrical, is long grows in gardens, grows on vines, is edible, is crunchy, used for making pickles, eaten in salads stove: is an appliance, produces heat, inside has elements, inside has an oven, made of metal, is hot, is electrical, runs on wood, runs on gas, found in kitchens, used for baking, used for cookng food You may be able to think of more and/or different types of properties for these concepts, but these examples should give you an idea of what is requested of you. Please do not languish an extraordinary amount of time on each word, but also please take a bit of time to consider the relevant properties of each entity or object. In other words, complete this questionnaire reasonably quickly, but keep the relevant types of properties in mind. Thank you very much for completing this questionnaire.
