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…

Age Differences in Visual Search for Compound Patterns: Long- Versus Short-Range Grouping.
Peer reviewed Peer reviewed
Burack, Jacob A.; Enns, James T.; Iarocci, Grace; Randolph, Beth – Developmental Psychology, 2000
Examined visual search for compound patterns in 6-, 8-, 10-, and 22-year-olds. Found large improvements with age in search rate for long-range targets; search rate for short-range targets was fairly constant across age. This pattern held regardless of ease of perceptual access to target, supporting the hypothesis of different processes involved at…

A Developmental Study of Shape Integration Over Space and Time.
Peer reviewed Peer reviewed
Enns, James T.; Girgus, Joan S. – Developmental Psychology, 1986
Three experiments with observers aged 6 to 21 years of age examined the integration of shape information over successive glances. Results indicated age-related improvements in the sequential integration of shape information, both when integration occurs through successive glimpses over space and when information is separated only in time.
