![]() ![]() Furthermore, as the mode of human locomotion shifts from crawling to walking, there is an additional shift in the alignment of the hippocampus that marks the beginning of adult-like episodic memory and the end of CA. That is, because the animal can now reliably discriminate locations, location becomes a stable cue for memories. Specifically, the onset of locomotion prompts the alignment of hippocampal place cells and grid cells to the environment, which in turn facilitates the ontogeny of long-term episodic memory and the end of IA. ![]() But why does the hippocampus mature at one time and not another, and how does that maturation relate to memory? Our hypothesis is rooted in theories of embodied cognition, and it provides an explanation both for hippocampal development and the end of IA. Evidence suggests that IA occurs across altricial species, and a number of studies using animal models have converged on the hypothesis that maturation of the hippocampus is an important factor. 2Department of Psychology, University of Wisconsin-Madison, Madison, WI, USAĪt least since the late nineteenth century, researchers have sought an explanation for infantile amnesia (IA)-the lack of autobiographical memories dating from early childhood-and childhood amnesia (CA), faster forgetting of events up until the age of about seven.1Department of Psychology, Arizona State University, Tempe, AZ, USA.The overall goal of the research is to provide a systematic body of knowledge about the preverbal foundations of thinking and remembering, so that we can better understand what young children need to know in order to learn language.Arthur M. This research will use several new techniques, involving the way that infants handle and explore objects, to test this hypothesis. However, research from Mandler's laboratory indicates that the broader concepts precede the more specific ones. It has traditionally been thought that infants first form concepts about concrete objects, such as dogs, chairs, and cars, and only later develop broader concepts of animals, furniture, and vehicles. There has also been little experimental work on concept formation in infancy. This research program will use deferred imitation, in which children are asked to imitate events they observed in the past, to measure recall in children too young to talk. However, recent work in Mandler's laboratory indicates that two-year-olds can recall events that occurred at age one. The phenomenon known as infantile amnesia, in which adults recall little or nothing about their early years, suggests that infants may not be able to remember their past for very long. ![]() Until recently, we had little information about the way infants conceptualize the world or how long they can recall events that have happened to them. This research will examine the development of conceptual thought in infants and young children and their ability to recall the past. ![]() Primary Place of Performance Congressional District: Jean Mandler (Principal Investigator) Sponsored Research Office:.BCS Division Of Behavioral and Cognitive Sci ![]()
