Despite decades of studies of human infants, a still open question concerns the role of visual experience in the development of the ability to perceive complete shapes over partial occlusion. Previous studies show that newborns fail to manifest this ability, either because they lack the visual experience required for perceptual completion or because they fail to detect the pattern of motion. To distinguish these possibilities, newborns' perception of a center-occluded object was tested, using stroboscopic motion. Infants (mean age of 72 hr) perceived the object as a connected unit, providing the first evidence that the newborn is capable of filling in gaps in the visible surface layout when the relevant visual information can be detected by his or her immature visual system. 相似文献

This registered report evaluated the efficacy of an Italian adaptation of the Identity Project, a school-based intervention promoting adolescents' cultural identity. Migration background and environmental sensitivity were explored as moderators. After adapting and piloting the intervention, a randomized controlled trial was conducted between October 2021 and January 2022 on 747 ethnically diverse adolescents (Mage = 15 years, 53% girls, 31% with migration background) attending 45 classrooms randomly assigned to the intervention or control condition. Bayesian analyses confirmed the efficacy of the Italian IP in enhancing exploration processes (Cohen's d = .18), whereas no cascading effect on resolution emerged. Youth with higher (vs. lower) levels of environmental sensitivity benefited more in terms of exploration. Implications for developmental theory and practice are discussed. 相似文献
