We reviewed literature to understand when a spatial map for time is available in the brain. We carefully defined the concepts of metrical map of time and of conceptual representation of time as the mental time line (MTL) in order to formulate our position. It is that both metrical map and conceptual representation of time are spatial in nature. The former should be innate, related to motor/impl...

* This research was supported by NIMH RO1 MH62480 and NSF BCS 00-91757, both awarded to JPS. Abstract – The Dynamic Field Theory (DFT) has been used to account for spatial recall biases in children and adults. This paper extends the DFT to a second spatial working memory task, position discrimination. The DFT captures details of adults’ discrimination performance, as well as predicting developm...

Genome remodeling occurs in cells as either a slow evolutionary process, or a rapid programmed developmental process. Intriguing examples of each type permeate the tree of life. This summer REU will feature research projects related to rapid programmed developmental processes. Algorithmic details of the developmental program of an organism allow one to investigate the mathematical and technolog...

Prospective memory (PM) is memory for delayed intentions. Despite its importance to everyday life, the few studies on PM function in adults with dyslexia which exist have relied on self-report measures. To determine whether self-reported PM deficits can be measured objectively, laboratory-based PM tasks were administered to 24 adults with dyslexia and 25 age- and IQ-matched adults without dysle...

To build a theory of social complexity, we need to understand how aggregate social properties arise from individual interaction rules. Here, I review a body of work on the developmental dynamics of pigtailed macaque social organization and conflict management that provides insight into the mechanistic causes of multi-scale social systems. In this model system coarse-grained, statistical represe...

Material and virtual entities alike undergo developmental processes. If they replicate, they evolve and adapt to a variety of developmental processes. Based on the notion that these processes rarely constitute a direct translation from one state to the next, we have taken a step towards formally capturing evolutionary development of time series. We iteratively extend the Knapsack Problem to con...
