Erratum: Developmental Changes in Mental Rotation: A Dissociation Between Object-Based and Egocentric Transformations
The present study was conducted to investigate developmental changes of mental rotation performance. We compared children, adults, and older adults regarding their performance in object-based and egocentric transformations. Both children and older adults showed higher overall reaction times compared to adults. Results were interpreted against the background of impaired working memory capacity i...
متن کاملMental Object Rotation and Egocentric Body Transformation: Two Dissociable Processes?
An important question in studies on mental rotation is whether the mental object rotation and the egocentric body transformation rely on dissociable mechanisms. We tested non-dancers and professional dancers as experts in the mental object rotation task (MORT, 3D-cubes used by Shepard & Metzler, 1971) and the mental body transformation task (MBRT, line drawings of human bodies similar to those ...
متن کاملObject-Centric Spatio-Temporal Pyramids for Egocentric Activity Recognition
Activities in egocentric video are largely defined by the objects with which the camera wearer interacts, making representations that summarize the objects in view quite informative. Beyond simply recording how frequently each object occurs in a single histogram, spatio-temporal binning approaches can capture the objects’ relative layout and ordering. However, existing methods use hand-crafted ...
متن کاملMental rotation performance in soccer players and gymnasts in an object-based mental rotation task
In this study, the effect of motor expertise on an object-based mental rotation task was investigated. 60 males and 60 females (40 soccer players, 40 gymnasts, and 40 non-athletes, equivalent males and females in each group) solved a psychometric mental rotation task with both cube and human figures. The results revealed that all participants had a higher mental rotation accuracy for human figu...
متن کاملSelective Effects of Sport Expertise on the Stages of Mental Rotation Tasks With Object-Based and Egocentric Transformations
It is well established that motor expertise is linked to superior mental rotation ability, but few studies have attempted to explain the factors that influence the stages of mental rotation in sport experts. Some authors have argued that athletes are faster in the perceptual and decision stages but not in the rotation stages of object-based transformations; however, stimuli related to sport hav...
