A new method was devised to test object permanence in young infants. Fivemonth-old infants were habituated to a screen that moved back and forth through a 180-degree arc, in the manner of a drawbridge. After infants reached habituation, a box was centered behind the screen. Infants were shown two test events: a possible event and an impossible event. In the possible event, the screen stopped when it reached the occluded box; in the impossible event, the screen moved through the space (...) occupied by the box. The results indicated that infants looked reliably longer at the impossible than at the possible event. This hnding suggested that infants (1) understood that the box continued to exist, in its same location, after it was occluded by the screen, and (2) expected the screen to stop against the occluded box and were surprised, or puzzled, when it failed to do so. A control experiment in which the box was placed next to the screen provided support for this interpretation of the results. Together, the results of these experiments indicate that, contrary to Piaget’s (1954) claims, infants as young as 5 months of age understand that objects continue to exist when occluded. The results, also indicate that 5-month-old infants realize that solid objects do not move through the space occupied by other solid objects. (shrink)

Four-month-old infants sometimes can perceive the unity of a partly hidden object. In each of a series of experiments, infants were habituated to one object whose top and bottom were visible but whose center was occluded by a nearer object. They were then tested with a fully visible continuous object and with two fully visible object pieces with a gap where the occluder had been. Pattems of dishabituation suggested that infants perceive the boundaries of a partly hidden object by analyzing (...) the movements of its surfaces: infants perceived a connected object when its ends moved in a common translation behind the occluder. Infants do not appear to perceive a connected object by analyzing the colors and forms of surfaces: they did not perceive a connected object when its visible parts were stationary, its color was homogeneous, its edges were aligned, and its shape was simple and regular. These findings do not support the thesis, from gestalt psychology, that object perception first arises as a consequence of a tendency to perceive the simplest, most regular configuration, or the Piagetian thesis that object perception depends on the prior coordination of action. Perception of objects may depend on an inherent conception of what an object is. (shrink)

Continuing his exploration of the organization of complexity and the science of design, this new edition of Herbert Simon's classic work on artificial ...

First published in 1977, this book draws together various contributions on the area of speech used by parents with their children. Numerous perspectives on the topic include the comparison of baby talk with other simplified registers by linguists, the analysis of cross-cultural differences in mother and child interaction by anthropologists, and the relation of language development to differences in styles of childcare and the child's social environment in general by psychologists. The text had its origins in a conference sponsored by (...) the Sociolinguistics Committee of the Social Science Research Council. It will be of value to anyone with an interest in language acquisition and development. (shrink)

This book contains the unfinished manuscript and working notes of the book Merleau-Ponty was writing when he died.

In this book, which remained unfinished at his death, Husserl attempts to forge a union between phenomenology and existentialism.

The Structures of the Life-World is the final focus of twenty-seven years of Alfred Schutz's labor, encompassing the fruits of his work between 1932 and his death in 1959. This book represents Schutz's seminal attempt to achieve a comprehensive grasp of the nature of social reality. Here he integrates his theory of relevance with his analysis of social structures. Thomas Luckmann, a former student of Schutz's, completed the manuscript for publication after Schutz's untimely death.

Dilthey is a figure of real importance in European philosophy and social theory. He exerted a significant influence on Husserl, Heidegger and Weber (among others) through his work on the nature of philosophy and the methodology and epistemology of human and social studies. He was also a distinguished and original historian of ideas and, indeed, many of his philosophical interests arose from the insights and practical difficulties he encountered as a historian. He produced a monumental biography of Schleiermacher, and a (...) series of shorter, but no less striking studies of Hegel, Dickens, Shakespeare, Schiller and many others. (shrink)

Four-month-old infants can perceive bimodally speciiied events. They respond to relationships between the optic and acoustic stimulation that carries information about an object. Infants can do this by detecting the temporal synchrony of an object’s sounds and its optically specified impacts. They are sensitive both to the common tempo and to the simultaneity of such sounds and visible impacts. These findings support the view that intermodal perception depends at least in part on the detection of invariant relationships in patterns of (...) light and sound. (shrink)

In this book, Granit explains the physiology of vision perception as an input system and motor control as an output system, with the goal-oriented brain mediating between.
