Perceptual Grouping and Spatial Distortion: A Developmental Study.
Peer reviewed Peer reviewed
Enns, James T.; Girgus, Joan S. – Developmental Psychology, 1985
Observers aged six to 24 years estimated distances between elements in patterns illustrating Gestalt grouping principles of proximity, similarity, closure, and good continuation. Magnitude of distance distortions decreased significantly with age, suggesting that perceptual development includes improving ability to disregard Gestalt groupings when…

Continuity and Discontinuity of Perceptual Development.
Fischer, Hardi – 1979
Despite external changes such as those of magnitudes, the functional properties of the visual system also improve with increased age. According to Jean Piaget's centration/decentration theory, the process of perceptual development might continue until adulthood and even after. However, perceptual development should not be understood in all of its…

The Development of Action Discrimination.
Newtson, Darren; And Others – 1980
Competence in action perception seems to be achieved very early in life. Because research has indicated that competent perceivers of action must be able to discriminate breakpoints in behavior, then recognition memory for breakpoints should be superior to that for nonbreakpoints at all ages where competence in action perception exists. Two studies…

Children's Perceptions of Death: A Look at the Appropriateness of Selected Picture Books.
Delisle, Robert G.; McNamee, Abigail S. Woods – 1977

Researchers generally agree that a child's perception of death is developmental, closely associated to either age or…

In the past 25 years, there has been an explosion in research on the development of perception. The research has produced discoveries at multiple levels: ecological analyses, models of representation and process, and improved understanding of biological mechanisms. This book provides a comprehensive treatment of infant perception, bringing…

Perception of Object Unity in 2-Month-Old Infants.
Peer reviewed Peer reviewed
Johnson, Scott P.; Aslin, Richard N. – Developmental Psychology, 1995
Examined perception of object unity in partial occlusion in 72 infants. Recorded how long subjects looked at a display of complete and incomplete rods. In test and control conditions, infants looked longer at broken rods than at complete rods, suggesting that infants' cognitive, visual, or attentional skills may be insufficient to support…
