Examined the contribution of global representation on object recognition, i.e., global diagnosticity (GD). It is suggested that global representation is prioritized by the recognition mechanism for a number of reasons and that objects high in GD are easier to recognize than objects low in GD. In addition, the effect of complexity on recognition was examined. Results of 3 experiments with healthy undergraduate subjects indicate that both GD and complexity affected the naming performance of briefly-exposed and backward masked objects in systematic ways. Globally diagnostic objects were recognized faster and more accurately than globally non-diagnostic ones (Exps 1-3). Recognition of non-diagnostic objects was found to be more susceptible than diagnostic objects due to manipulation by duration exposure (Exp 2), as well as location uncertainty and presentation location (Exp 3). U-shaped complexity effects were further found in reaction time data of diagnostic objects and the error rate data of non-diagnostic objects (Exps 1-3). Implications for models of object recognition and researches adopting object stimuli were also discussed. (PsycINFO Database Record (c) 2017 APA, all rights reserved)
