From a perceptual learning perspective, infants use social information (like gaze direction) in a similar way as other information in our physical environment (like object movements) to specify action possibilities. In the current study, we assumed that infants are able to learn an affordance upon observing an adult failing to act out that…

Infants require locomotor experience to behave adaptively at a drop-off. However, different experimental paradigms (visual cliff and actual gaps and slopes) have generated conflicting findings regarding what infants learn and the specificity of their learning. An actual, adjustable drop-off apparatus was used to investigate whether learning to…

A modified Visual Expectation Paradigm assessed the role of picture content in the spatiotemporal expectations of 80 infants. Stable picture content information facilitated formation of expectations about when and where pictures would appear. Two month olds' reactions were consistently slower than those of three month olds.(LB)

An Ames static trapezoidal window was used to test infants' responsiveness to pictorial depth. Sensitivity to the pictorial information for depth that is present in the trapezoidal window appears to develop after the age of 22 weeks. (Author/DB)

Fourteen-month-old infants saw an object hidden inside a container and were removed from the disappearance locale for 24 hr. Upon their return, they searched correctly for the hidden object, demonstrating object permanence and long-term memory. Control infants who saw no disappearance did not search. In Experiment 2, infants returned to see the…

The development of sensory and perceptual ability in infants is an important area of infancy research. This book reflects current knowledge of perceptual development and points to some of the many questions that remain unanswered. The book is divided into four parts. Part 1, "How the Visual System Develops: Normal and Abnormal…

The third Fenno-Hungarian Conference on Developmental Psychology covered four main concepts: the historical roots and development of social competence through three generations, parent-child interaction, parenthood, and the development of socio-cognitive competence through childhood and adolescence. A series of papers was presented addressing the…
