Abstract
This work presents a new set of 360 high quality colour images belonging to 23 semantic subcategories. Two hundred and thirty-six Spanish speakers named the items and also provided data from seven relevant psycholinguistic variables: age of acquisition, familiarity, manipulability, name agreement, typicality and visual complexity. Furthermore, we also present lexical frequency data derived from Internet search hits. Apart from the high number of variables evaluated, knowing that it affects the processing of stimuli, this new set presents important advantages over other similar image corpi: (a) this corpus presents a broad number of subcategories and images; for example, this will permit researchers to select stimuli of appropriate difficulty as required, (e.g., to deal with problems derived from ceiling effects); (b) the fact of using coloured stimuli provides a more realistic, ecologically-valid, representation of real life objects. In sum, this set of stimuli provides a useful tool for research on visual object-and word- processing, both in neurological patients and in healthy controls.
Highlights
Throughout the last 30 years, many clinical and experimental studies on cognitive processing have been performed with the items created by Snodgrass and Vanderwart (S&V) [1]
The goal of the present work was twofold: (a) to present a broad set of high quality ecological colour photographs, on white backgrounds, across a difficulty range to deal with problems derived from ceiling effects; and (b) to give detailed norms, derived from a large group of healthy participants, of several relevant psycholinguistic variables, some of them not sufficiently studied in several previous works: age of acquisisiton (AoA), familiarity, manipulability, name agreement, typicality and visual complexity, as well as lexical frequency
Both indexes are measures of name agreement, the latter indicates only how dominant the most common name is in a sample, whereas H is sensitive to how widely distributed responses are over all the unique names that are provided for a picture
Summary
Throughout the last 30 years, many clinical and experimental studies on cognitive processing (i.e., exploring memory, attention or language) have been performed with the items created by Snodgrass and Vanderwart (S&V) [1] These authors standardized their stimuli in four variables relevant to cognitive processing: familiarity, image agreement, name agreement and visual complexity. More familiar items, those with higher name and image agreement, as well as those with lesser visual complexity, are more named both by intact and neurological participants [2,3,4,5] Apart from these variables, other cognitive and psycholinguistic variables such as age of acquisisiton (AoA) and manipulability and typicality of items significantly affect cognitive processing. Only a few recent works have provided ratings of AoA [19] or manipulability [10], and, to our knowledge, only [25,30] have presented ratings of both variables concurrently, but with a relatively sparse number of items, as they only studied 140 [30] and 112 [25] coloured stimuli
