| Cognitive Robotics: An embodied model of the development of spatial cognition. |
| What are the precursors to spatial cognition? Some researchers (e.g., Corkum & Moore, 1998) have argued that one of the earliest forms of spatial cognition is gaze-following by pre-verbal infants. We present a series of computational models that model various ages, stages and capabilities where gaze-following is learned. We will present our results in several ways, including a computational representation, and computer simulations, and embodied models running on physical robots. |

Caffeine's Effect on Appraisal and Mental Arithmetic Performance:
A Cognitive Modeling Approach Tells Us More |
|
A human subject experiment was conducted to investigate caffeine's effect on appraisal and performance of a mental serial subtraction task. Serial subtraction performance data was collected from three treatment groups: placebo, 200 mg caffeine, and 400 mg caffeine. Data were analyzed by average across treatment group and by challenge and threat task appraisal conditions. A cognitive model of the serial subtraction task was developed in ACT-R 6.0 and fit to the human performance data. How the model's parameters change to fit the data suggest how cognition changes across treatments and due to appraisal. Overall, the cognitive modeling and optimization results suggest that the speed of vocalization is changed the most along with some changes to declarative memory. This approach promises to offer fine-grained knowledge about the effects of moderators on task performance.

THE ART AND SCIENCE OF MAKING UP YOUR MIND:
LOGICAL RIGOR AND BEHAVIORAL REALISM |
Dr. Brown has split his career between developing decision aiding tools and applying them to live issues. His writings include Rational Choice and Judgment and Teaching Decision Skills to Adolescents. He has taught decision analysis at LSE (psychology), Cambridge (statistics) and Harvard (management). As Chairman of Decision Science Consortium, Inc., he advised senior government officials on public policy, and appeared on talk shows and the cover of The Illustrated London News. Since retiring, he has focused on private decision-making – both personal and civic – and is preparing a general education text-book. He will discuss how imperfect humans can use pre-quantitative decision theory on everyday choices. |
