True or False: Do 5-Year-Olds Understand Belief?
Peer reviewed Peer reviewed
Direct linkDirect link
Fabricius, William V.; Boyer, Ty W.; Weimer, Amy A.; Carroll, Kathleen – Developmental Psychology, 2010
In 3 studies (N = 188) we tested the hypothesis that children use a perceptual access approach to reason about mental states before they understand beliefs. The perceptual access hypothesis predicts a U-shaped developmental pattern of performance in true belief tasks, in which 3-year-olds who reason about reality should succeed, 4- to 5-year-olds…

Seeing It Happen and Knowing How It Works: How Children Understand the Relation between Perceptual Causality and Underlying Mechanism.
Peer reviewed Peer reviewed
Schlottmann, Anne – Developmental Psychology, 1999
Two studies investigated how 5- to 10-year-olds integrate perceptual causality with their knowledge of the underlying causal mechanism, using two devices in which a bell would ring when a ball was dropped in, either immediately or after a delay, depending on the mechanism inside. Findings suggest a link between temporal contiguity and causality in…

Detection of Information Specifying the Motion of Objects by 3- and 5-Month-Old Infants.
Peer reviewed Peer reviewed
Ruff, Holly A. – Developmental Psychology, 1985
Two studies investigated three- and five-month-old infants' ability to discriminate and recognize different motions of rigid objects. Also explored was the nature of stimulus information which makes such discrimination and recognition possible. The results are discussed in terms of disruptions in the optic array. (Author/DST)

Infants' Perception of Dynamic Relations between Objects: Passing through or Support?
Peer reviewed Peer reviewed
Sutskoorn, Margriet M.; Smitsman, Ad W. – Developmental Psychology, 1995
Four experiments investigated 4-, 6-, and 9-month-old infants' ability to perceive whether the width relationship between a block and the opening of a box specified passing through or support. Found that six- and nine-month olds looked significantly longer than four-month olds when a block wider than a box opening passed through this opening. (MDM)

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…

Young Children's Perceptions of Television Reality: Determinants and Developmental Differences.
Peer reviewed Peer reviewed
Wright, John C.; And Others – Developmental Psychology, 1994
Five and seven year olds were able to correctly distinguish between factual and fictional television programs and test clips, based upon genre of program, production features, content. Age and vocabulary scores predicted accuracy of factuality judgments, but television viewing history did not. Older children understood better than younger ones…

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…
