Structural dimensions of object pictures: Organization and relation to object decision and naming

摘要

The present paper evaluated the nature of the organization of 22 structural measures of object pictures from the Snodgrass and Vanderwart (1980) picture set (Study 1), and their contribution to object decision and to object naming latencies (Studies 2 and 3). Study 1 employed a principal components analysis and provided evidence of four underlying components: a??Object partsa??, a??internal detailsa??, a??object contoursa??, and a??variability of the representationa??. Study 2 examined the contribution of these components to object decision and object naming and highlighted variability of the representation and internal details as the most relevant indexes of structural similarity. Study 3 investigated the interactions between these structural components and lexical frequency. Main results showed an interaction effect between variability of the representation and lexical frequency and other effects associated to internal details. Implications for the concept of structural similarity and for object recognition are discussed from a continuous and cascade processing perspective.View full textDownload full textKeywordsObject decision, Object naming, Object recognition, Structural similarity, Structural variablesRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; var addthis_config = {"data_track_addressbar":true,"ui_click":true}; Add to shortlist Link Permalink http://dx.doi.org/10.1080/13506285.2011.575414
