Pan, Jinger; Yan, Ming; Laubrock, Jochen; Shu, Hua; Kliegl, Reinhold – Developmental Science, 2013
We measured Chinese dyslexic and control children's eye movements during rapid automatized naming (RAN) with alphanumeric (digits) and symbolic (dice surfaces) stimuli. Both types of stimuli required identical oral responses, controlling for effects associated with speech production. Results showed that naming dice was much slower than naming…

Valenza, Eloisa; Bulf, Hermann – Developmental Science, 2011
The present study aimed to investigate whether perceptual completion is available at birth, in the absence of any visual experience. An extremely underspecified kinetic visual display composed of four spatially separated fragments arranged to give rise to an illusory rectangle that occluded a vertical rod (illusory condition) or rotated so as not…

Luo, Yuyan; Johnson, Susan C. – Developmental Science, 2009
The present research examined whether infants as young as 6 months of age would consider what objects a human agent could perceive when interpreting her actions on the objects. In two experiments, the infants took the agent's actions of repeatedly reaching for and grasping one of two possible objects as suggesting her preference for that object…

Leo, Irene; Simion, Francesca – Developmental Science, 2009
The present study was aimed at exploring newborns' ability to recognize configural changes within real face images by testing newborns' sensitivity to the Thatcher illusion. Using the habituation procedure, newborns' ability to discriminate between an unaltered face image and the same face with the eyes and the mouth 180 degrees rotated (i.e.…

Bremner, J. Gavin; Johnson, Scott P.; Slater, Alan; Mason, Uschi; Cheshire, Andrea; Spring, Joanne – Developmental Science, 2007
When viewing an event in which an object moves behind an occluder on part of its trajectory, 4-month-old infants perceive the trajectory as continuous only when time or distance out of sight is short. Little is known, however, about the conditions under which young infants perceive trajectories to be discontinuous. In the present studies we focus…
