by the coauthors, preceding and during the AGI Roadmap Workshop held at the University of Tennessee, Knoxville in October 2009, and from many continuing discussions since then. Some of the ideas also trace back to discussions held during two Evaluation and Metrics for Human Level AI workshopa organized by John Laird and Pat Langley (one in Ann Arbor in late(More)
Trial-and-error learning strategies play a central role in sensorimotor development during early infancy. However, learning to reach by trial-and-error normally requires a slow and laborious search through the space of possible movements. We propose a computational model of reaching based on the notion that early sensorimotor control is driven by the(More)
There is a growing debate among developmental theorists concerning the perception of causality in young infants. Some theorists advocate a top-down view, e.g., that infants reason about causal events on the basis of intuitive physical principles. Others argue instead for a bottom-up view of infant causal knowledge, in which causal perception emerges from a(More)
The emerging field of Evolutionary Computation (EC), inspired by neo-Darwinian principles (e.g. natural selection, mutation, etc. ), offers developmental psychologists a wide array of mathematical tools for simulating ontogenetic processes. In this brief review; I begin by highlighting three of the approaches that EC researchers employ (Artificial Life,(More)
The agent-based approach emphasizes the importance of learning through organism-environment interaction. This approach is part of a recent trend in computational models of learning and development toward studying autonomous organisms that are embedded in virtual or real environments. In this paper we introduce the concepts of online and offline sampling and(More)
Infants' developing causal expectations for the outcome of a simple tool-use event from ages 8 to 12 months were investigated. Causal expectations were studied by comparing infants' developing tool-use actions (i.e. as tool-use agents) with their developing perceptual reactions (i.e. as tool-use observers) to possible and impossible tool-use events. In(More)
Recent work by Amso and Johnson (Developmental Psychology, 42(6), 1236–1245, 2006) implicates the role of visual selective attention in the development of perceptual completion during early infancy. In the current article, we extend this finding by simulating the performance of 3-month-old infants on a visual search task, using a multi-channel,(More)
We have recently used a multi-channel, imagefiltering model to study the development of visual selective attention in human infants (Schlesinger, Amso, & Johnson, 2007). In the current study, we employ the same model to simulate infants’ gaze patterns during a perceptual completion task. The model not only succeeds in capturing the gaze patterns produced by(More)
