“…Previous studies used repetition priming to examine the representation of possible and impossible objects in long-term memory. Evidence from behavioral (Schacter et al, 1990;Soldan et al, 2009), neuroimaging (Habeck et al, 2006;Schacter et al, 1995) and electrophysiological studies (Soldan et al, 2006) suggest qualitative differences between the long-term memory representations of these objects. In the current study, we present new evidence suggesting that the initial perception of possible and impossible objects may rely on shared neural mechanisms, and thus the differences between these object types may be attributed to late processing stages, that occur after initial object recognition.…”

“…The object decision task was introduced by Schacter et al (1990) and has been extensively used since (e.g. Habeck et al, 2006;Soldan et al, 2009;Williams and Tarr, 1997). However, the suitability of this task to imaging studies is questionable.…”

“…Due to their unusual structure, impossible objects were often used in the literature as a tool for investigating the representation of structural, spatial information using various behavioral (e.g. Schacter et al, 1990;Soldan et al, 2009;Williams and Tarr, 1997) and imaging experiments (e.g. Schacter et al, 1995;Habeck et al, 2006).…”

“…The object selection procedure we used in this study was similar to that presented in Perdreau and Cavanagh, (2013b) . Part of the set of possible and impossible objects used in the present study was taken from previous collections ( Schacter et al, 1991 ; Soldan, Hilton, & Stern, 2009 ; used with authors' permission). The other objects were outlined versions of impossible objects provided by an Internet database (“Impossible world” website), and one of the authors (PF) designed corresponding possible versions using Adobe Illustrator CS4.…”

Accurate drawing calls on many skills beyond simple motor coordination. A good internal representation of the target object's structure is necessary to capture its proportion and shape in the drawing. Here, we assess two aspects of the perception of object structure and relate them to participants' drawing accuracy. First, we assessed drawing accuracy by computing the geometrical dissimilarity of their drawing to the target object. We then used two tasks to evaluate the efficiency of encoding object structure. First, to examine the rate of temporal encoding, we varied presentation duration of a possible versus impossible test object in the fovea using two different test sizes (8° and 28°). More skilled participants were faster at encoding an object's structure, but this difference was not affected by image size. A control experiment showed that participants skilled in drawing did not have a general advantage that might have explained their faster processing for object structure. Second, to measure the critical image size for accurate classification in the periphery, we varied image size with possible versus impossible object tests centered at two different eccentricities (3° and 8°). More skilled participants were able to categorise object structure at smaller sizes, and this advantage did not change with eccentricity. A control experiment showed that the result could not be attributed to differences in visual acuity, leaving attentional resolution as a possible explanation. Overall, we conclude that drawing accuracy is related to faster encoding of object structure and better access to crowded details.

Prior work showed that infants look longer at impossible figures than possible ones, although it is unclear whether they or older children understand “impossibility.” We employed a series of matching and sorting tasks with pictures and objects to evaluate children's knowledge of this dimension. In Experiment 1, nearly all children successfully matched depicted and real objects, detected that possible and impossible objects differed, and identified structure–function relations of possible objects. In Experiment 2, children struggled to identify impossibility as a global characteristic for sorting. Few children sorted by impossibility, with a majority sorting by other shape similarities (e.g., round vs. straight). After receiving instructions, fewer than half sorted by possibility. Many children sorted by symmetry on their own, and the remainder performed perfectly after training. Children readily sorted by complexity. In Experiment 3, children sorted by possibility with few errors after elaborate instructions. Three‐year‐olds made significantly more errors than did older children, suggesting that selective attention to spatial geometry improves with experience. For children and adults, structural incoherence is challenging to recognize as a unifying property for grouping objects. Children may show implicit responses to impossible figures but often do not realize that they are in fact impossible. Highlights Infants and children respond with increased interest toward impossible figures, but do they understand that such objects are structurally impossible? We used matching and sorting tasks with both depicted and real objects to evaluate preschool‐age children's implicit and explicit knowledge of object possibility. Children may show implicit responses to impossible figures, but they do not spontaneously realize that they are in fact impossible. If explicitly asked to evaluate figures, children are generally able to identify possible and impossible figures.
