Picture perfect: A stimulus set of 225 pairs of matched clipart and photographic images normed by Mechanical Turk and laboratory participants

Abstract

The present study provides normative measures for a new stimulus set of images consisting of 225 everyday objects, each depicted both as a photograph and a matched clipart image generated directly from the photograph (450 images total). The clipart images preserve the same scale, shape, orientation, and general color features as the corresponding photographs. Various norms (modal name and verb agreement measures, picture–name agreement, familiarity, visual complexity, and image agreement) were collected separately for each image type and in two different contexts: online (using Mechanical Turk) and in the laboratory. We discuss similarities and differences in the normative measures according to both image type and experimental context. The full set of norms is provided in the supplemental materials.Electronic supplementary materialThe online version of this article (10.3758/s13428-018-1028-5) contains supplementary material, which is available to authorized users.

Peer Review #3 of "Examining the influence of picture format on children’s naming responses (v0.1)"

“…For instance, Uttl et al (2006) suggested that a schematic representation of an object, such as a line drawing, might usually be perceived as a representation of a class of object or type, rather than as a representation of an individual object or token, like in the perception of photographs. Previous studies have provided support for the assumption of different sensory and perceptual processes for the identification of photographs and line drawings, such as strong embodiment and associations with real-world tangible objects (Salmon et al, 2014;Saryazdi et al, 2018). Further, similar findings in the previous literature have highlighted visual iconicity as one of the variables that particularly affects the performance of both children and adults.…”

“…Manuscript to be reviewed scale, and orientation features between drawings and photographs (Price & Humphreys, 1989;Brodie, Wallace, & Sharrat, 1991;Saryazdi et al, 2018). Of those, the image types and the naming variables examined differed between the different studies.…”

Peer Review #1 of "Examining the influence of picture format on children’s naming responses (v0.2)"

“…Previous research with young children showed the impact of visual iconicity on tasks involving the matching of pictures with real objects, with better performance for photographs than for line drawings (Callaghan, 2000;Ganea et al, 2008). More recently, a subtle iconicity effect in picture naming has also been found in adults (Saryazdi et al, 2018). Our results in children using a picture-naming task showed that the more iconic representation (photograph) produced, the better name agreement measures were obtained, better than the measures of less iconic representation (line drawing).…”

“…A pioneering normative study is the one reported by Snodgrass and Vanderwart (1980). This consisted of 260 black-and-white line drawings with norms for name agreement, image agreement (or the degree of agreement between the mental Brodeur, Dionne-Dostie, Montreuil, & Lepage, 2010;and Brodeur, Guérard, & Bouras, 2014;in English and French;Saryazdi, Bannon, Rodrigues, Klammer, & Chambers, 2018;in Turkish;Shao & Stiegert, 2016;in Dutch;Moreno-Martínez & Montoro, 2012;in Spanish;Navarrete, Arcara, Mondini, & Penolazzi, 2019;in Italian). Thus, the need for more ecological stimuli than those provided by line drawings has begun to be highlighted.…”

PicPsy: A new bank of 106 photographs and line drawings with written naming norms for Spanish-speaking children and adults

“…Other photographic datasets with norms for adults are the set published by Viggiano et al [ 43 ], in English and Italian; the Hatfield Image Test [ 46 ], in English; the C.A.R.E. set [ 47 ] in English; the set of Shao & Stiegert [ 48 ] in Dutch; the set of Saryazdi, Bannon, Rodrigues, Klammer, & Chambers [ 49 ], in Turkish. The ecological version of the Snodgrass and Vanderwart [ 3 ] set [ 42 ] is the only one in Spanish, and has recently been published also in Italian [ 50 ].…”
