Face Preference in Infancy and Its Relation to Motor Activity
Peer reviewed Peer reviewed

Libertus, Klaus; Needham, Amy – International Journal of Behavioral Development, 2014
Infants' preference for faces was investigated in a cross-sectional sample of 75 children, aged 3 to 11 months, and 23 adults. A visual preference paradigm was used where pairs of faces and toys were presented side-by-side while eye gaze was recorded. In addition, motor activity was assessed via parent report and the relation between motor…

Bertenthal, Bennett I.; Gredeback, Gustaf; Boyer, Ty W. – Child Development, 2013
Sixty infants divided evenly between 5 and 7 months of age were tested for their knowledge of object continuity versus discontinuity with a predictive tracking task. The stimulus event consisted of a moving ball that was briefly occluded for 20 trials. Both age groups predictively tracked the ball when it disappeared and reappeared via occlusion,…

Visual Data Mining: An Exploratory Approach to Analyzing Temporal Patterns of Eye Movements
Peer reviewed Peer reviewed

Yu, Chen; Yurovsky, Daniel; Xu, Tian – Infancy, 2012
Infant eye movements are an important behavioral resource to understand early human development and learning. But the complexity and amount of gaze data recorded from state-of-the-art eye-tracking systems also pose a challenge: how does one make sense of such dense data? Toward this goal, this article describes an interactive approach based on…

Thomas, Shery; Proudlock, Frank A.; Sarvananthan, Nagini; Roberts, Eryl O.; Awan, Musarat; McLean, Rebecca; Surendran, Mylvaganam; Kumar, A. S. Anil; Farooq, Shegufta J.; Degg, Chris; Gale, Richard P.; Reinecke, Robert D.; Woodruff, Geoffrey; Langmann, Andrea; Lindner, Susanne; Jain, Sunila; Tarpey, Patrick; Raymond, F. Lucy; Gottlob, Irene – Brain, 2008
Idiopathic infantile nystagmus (IIN) consists of involuntary oscillations of the eyes. The familial form is most commonly X-linked. We recently found mutations in a novel gene "FRMD7" (Xq26.2), which provided an opportunity to investigate a genetically defined and homogeneous group of patients with nystagmus. We compared clinical features and eye…
