The First Time Ever I Saw Your Feet: Inversion Effect in Newborns' Sensitivity to Biological Motion
Peer reviewed Peer reviewed
Direct linkDirect link
Bardi, Lara; Regolin, Lucia; Simion, Francesca – Developmental Psychology, 2014
Inversion effect in biological motion perception has been recently attributed to an innate sensitivity of the visual system to the gravity-dependent dynamic of the motion. However, the specific cues that determine the inversion effect in naïve subjects were never investigated. In the present study, we have assessed the contribution of the local…

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…

The Effect of Perceptual Salience on Reflective-Impulsive Performance Differences
Peer reviewed Peer reviewed
Hartley, Deborah Green – Developmental Psychology, 1976
A total of 174 first, second, and third graders were tested to examine the relation between perceptual salience and cognitive style. The results indicated that implusives made more errors than reflectives only on trials requiring the use of the least salient dimension and that these performance differences decreased with age.

Spatial Determinants in the Perception of Self-Produced Leg Movements by 3- to 5-Month-Old Infants.
Peer reviewed Peer reviewed
Rochat, Philippe; Morgan, Rachel – Developmental Psychology, 1995
Three experiments examined infants' perceptions of their own leg movements as presented to them via online video that varied the spatial orientation and directionality of movement. The infants looked significantly longer and generated significantly more leg activity while looking at the view displaying a left-right inversion than while looking at…

Relationship between Visual and Tactual Exploration by 6-Month-Olds.
Peer reviewed Peer reviewed
Bushnell, Emily W.; And Others – Developmental Psychology, 1985
Investigating relationship between infants' visual and tactual exploration, looking and touching responses of 6-month-olds to objects only visually or tactually novel were observed. Results indicated infants were capable of tactual recognition memory, that temperature was salient object property, and that visual and tactual exploration are not…

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…
