Adaptive Critics and the Basal Ganglia

by Andrew G. Barto - In , 1995
"... One of the most active areas of research in artificial intelligence is the study of learning methods by which “embedded agents ” can improve performance while acting in complex dynamic environments. An agent, or decision maker, is embedded in an environment when it receives information from, and act ..."

Scaffolding Critical Reasoning about History and

by John W. Saye, Thomas Brush - Social Issues in Multimedia-Supported Learning Environments Educational Technology Research and Development , 2002
"... This article advances a continuing line of research that investigates the potential of hypermedia resources and scaffolding for supporting problem-based social studies and developing critical reasoning. Our line of inquiry consists of a series of generative design experiments that informs problem-ba ..."

Coalition Information Sharing: Lessons from K sovo

by Larry K. Wentz
"... Increased civil-military involvement in peacekeeping and humanitarian operations around the world is matched in part by the rise in the number and complexity of these situations. There are many more actors on today’s peace operations battlefield with competing as well as common interests and expecta ..."

traditions and behavior patterns. All actors need to better understand each other and the roles they can and should play in an increasingly complex operational environment. In order to obtain closure and improve information sharing in the future, the actors must develop relationships based on mutual trust

Longer-term effects of Head Start

by Eliana Garces , Duncan Thomas , Janet Currie Ucla , Nber - American Economic Review , 2002
"... Abstract Public early intervention programs like Head Start are often justified as investments in children. Yet nothing is known about the long-term effects of Head Start. This paper draws on unique data from the Panel Study of Income Dynamics to provide new evidence on the effects of Head Start on ..."

our analysis of these non-experimental data as an important complement to experimental sources and a first step towards establishing whether Head Start confers long-term benefits on participants. For reasons spelled out in detail below, our methods likely provide lower bound estimates of any positive

How and when does complex reasoning occur? Empirically driven development of a learning progression focused on complex reasoning about biodiversity

by Nancy Butler Songer, Ben Kelcey, Amelia Wenk Gotwals - Journal of Research in Science Teaching , 2009
"... Abstract: In order to compete in a global economy, students are going to need resources and curricula focusing on critical thinking and reasoning in science. Despite awareness for the need for complex reasoning, American students perform poorly relative to peers on international standardized tests m ..."

A dynamic model of social network formation.

by Brian Skyrms , Robin Pemantle - Proc. Nat. Acad. Sci. U.S.A. , 2000
"... We consider a dynamic social network model in which agents play repeated games in pairings determined by a stochastically evolving social network. Individual agents begin to interact at random, with the interactions modeled as games. The game payoffs determine which interactions are reinforced, and ..."

their environment. But they may also exert control over their environment. The players may have choice over the pairings but not perfect information about the other players. They may improve their lot in two different ways. A child who is being bullied learns either to fight better or to run away. Similarly, a

Materials for an exploratory theory of the network society.

by Manuel Castells , Anthony Giddens , Alain Touraine , Anthony Smith , Benjamin Barber , Peter Hall , Roger-Pol Droit , Sophie Watson , Frank Webster , Krishan Kumar , David Lyon , Craig Calhoun , Jeffrey Henderson , Ramon Ramos , Jose E Rodrigues-Ibanez , Jose F Tezanos , Mary Kaldor , Stephen Jones , Christopher Freeman - The British Journal of Sociology , 2000
"... ABSTRACT This article aims at proposing some elements for a grounded theor y of the network society. The network society is the social structure characteristic of the Information Age, as tentatively identi ed by empirical, cross-cultural investigation. It permeates most societies in the world, in v ..."

Thus, overall the new state is not any longer a nation-state. The state in the information age is a network state, a state made out of a complex web

THE ROLE OF CONTEXT IN THE DEVELOPMENT OF STUDENTS ’ INFORMAL INFERENTIAL REASONING

by Dani Ben-zvi, Einat Gil
"... The role of context is discussed in the setting of an extended curriculum development and research project in primary school designed to develop and study students ' reasoning about statistical inference. Qualitative research methods are used to critically dissect the roles of context in the em ..."

Intelligent Social Learning

by Rosaria Conte , 2000
"... One of the cognitive processes responsible for social propagation is social learning, broadly meant as the process by means of which agents' acquisition of new information is caused or favoured by their being exposed to one another in a common environment. Social learning results from one or ..."

Genetic experiments with animal learning: a critical review. Behavioral bioology 7

by Douglas Wahlsten , 1972
"... Abstract: The basic patterns of inheritance of learning ability in animals have been delineated. Summaries of strain differences in learning rate, responses to selective breeding for learning, heritabilities of learning phenotypes, and heterosis and overdominance are presented. In addition, the pat ..."

, the first issue to be raised is whether genes affect learning at all. To the student of animal behavior in 1971, it seems a little unbelievable that informed scientists ever seriously questioned the involvement of genotype in the learning process, given that genetic effects upon physical and chemical
