Stephen Grossberg

Two talk titles

1. Paradigms, Methods, and Objects

Brain paradigms and research methods for understanding
object attention, conscious seeing, learning, invariant recognition, and search

2. Space and Time

Spatial navigation, cognitive working memory, and conscious speech perception

The first part of lecture 1 provides an overview to ground the listeners for what will follow. I will then discuss recent models of object attention, conscious seeing, learning, invariant recognition, and search. This should be of interest to both biologists and technologists. Along the way, I explain a lot of data and make experimental predictions.

The second lecture complements the first. It explains how entorhinal grid and place cells can be learned and uses the same model to simulate a lot of challenging psychological and neurobiological data about spatial navigation. Then it switches gears to discuss how sequences of events are stored temporarily in working memory while being unitized, or chunked, into familiar words, plans, or skills. Then it describes recent modeling of conscious speech perception using this foundation.


Stephen Grossberg is Wang Professor of Cognitive and Neural Systems; He is a principal founder and current research leader in computational neuroscience, connectionist cognitive science, and neuromorphic technology. In 1957-58, Grossberg introduced the paradigm of using nonlinear systems of differential equations, including widely used equations for short-term memory (STM), or neuronal activation; medium-term memory (MTM), or activity-dependent habituation; and long-term memory (LTM), or neuronal learning. His work focuses upon how individuals adapt autonomously in real-time to unexpected environmental challenges, and includes models of vision and visual cognition; object, scene, and event recognition; audition, speech and language; development; cognitive information processing; reinforcement learning and cognitive-emotional interactions; navigation; social cognition; sensory-motor control and planning; mental disorders; and neuromorphic technology. Grossberg founded key infrastructure of the field of neural networks, including the International Neural Network Society and the journal Neural Networks. He is a fellow of AERA, APA, APS, IEEE, INNS, MDRS, and SEP. He has published 17 books or journal special issues, over 500 research articles, and has 7 patents. He was most recently awarded the 2015 Lifetime Achievement Award of the Society of Experimental Psychologists.
