The ability to learn new tasks and generalize performance to others is one of the most remarkable characteristics of the human brain and of recent AI systems. The ability to perform multiple tasks simultaneously is also a signature characteristic of large-scale parallel architectures, that is evident in the human brain, and has been exploited effec...

We studied social decision-making in the rule-based improvisational dance There Might Be Others, where dancers make in-the-moment compositional choices. Rehearsals provided a natural test-bed with communication restricted to non-verbal cues. We observed a key artistic explore–exploit tension in which the dancers switched between exploitation of exi...

This paper studies artistic expression in human movement by exploring the performance art form salsa. The motions of a salsa performance are constructed as concatenations of motion primitives, each of which specifies the movement of the dance pair over the course of eight musical beats. To analyze the syntax of artistic expression, the choreography...

One of the most salient and well-recognized features of human goal-directed behavior is our limited ability to conduct multiple demanding tasks at once. Previous work has identified overlap between task processing pathways as a limiting factor for multitasking performance in neural architectures. This raises an important question: insofar as shared...

This paper introduces a formal method to model the level of demand on control when executing cognitive processes. The cost of cognitive control is parsed into an intensity cost which encapsulates how much additional input information is required so as to get the specified response, and an interaction cost which encapsulates the level of interferenc...

Our limited ability to conduct multiple control-demanding tasks at once is one of the most salient and well-recognized features of human goal-directed behavior. In this work we investigate the source of this constraint from the perspective of a tradeoff between the efficiency of task representations and multitasking (parallel processing) capability...

Cognitive control -- the capacity to carry out goal-directed behavior in the face of compelling or distracting alternatives -- is a hallmark of human cognitive function. One of the defining, and best documented findings concerning cognitive control is the stark limitation on its ability for multitasking -- the simultaneous execution of multiple con...

The limited ability to simultaneously perform multiple tasks is one of the most salient features of human performance and a defining characteristic of controlled processing. We propose that this reflects the degree to which individual tasks rely on shared representations, and the constraints this places on parallel processing in neural network arch...

A key feature of neural networks is their ability to support the simultaneous interaction among large numbers of processes in the learning and processing of representations. However, how the richness of such interactions trades off against the ability of a network to simultaneously carry out multiple in- dependent processes – a salient limitation i...

Flying animals accomplish high-speed navigation through fields of obstacles using a suite of sensory modalities that blend spatial memory with input from vision, tactile sensing, and, in the case of most bats and some other animals, echolocation. Although a good deal of previous research has been focused on the role of individual modes of sensing i...

This study proposes a formal way of representing the dancers in a salsa performance as a transition system. The model involves two finite state machines that communicate through a channel and the goal is to understand the notion of optimality in salsa. This is achieved by integrating two complexity metrics that measure the energy and entropy of the...

Animals within groups need to coordinate their reactions to perceived environmental features and to each other in order to safely move from one point to another. This paper extends our previously published work on the flight patterns of Myotis velifer that have been observed in a habitat near Johnson City, Texas. Each evening, these bats emerge fro...

This paper summarizes work that investigates human interactions in terms of communication through motion in cooperative control. We are interested in multi-agent distributed control models with a shared goal and with the agents being required to accomplish secondary objectives. The study presented here extends the earlier work on the analysis of le...

This chapter summarizes work to understand various aspects of the communication that occurs through the movements of partners in a dance. The first part of the paper adopts the terminology of motion description languages and deconstructs an elementary form of the well-known popular dance, salsa, in terms of four motion primitives (dance steps). The...

The movements of birds, bats, and other flying species are governed by complex sensorimotor systems that allow the animals to react to stationary environmental features as well as to wind disturbances, other animals in nearby airspace, and a wide variety of unexpected challenges. The paper and talk will describe research that analyzes the three-dim...

The paper describes results on two components of a research program focused on motion-based communication mediated by the dynamics of a control system. Specifically we are interested in how mobile agents engaged in a shared activity such as dance can use motion as a medium for transmitting certain types of messages. The first part of the paper adop...
