this paper, we contribute to this line of work by presenting preliminary results from a new model of skilled (i.e., adult) arithmetic which, among other things, synthesizes selected components of existing models (Ashcraft, 1987; Campbell & Graham, 1985; Siegler, 1988)

This chapter describes an interactive activation model of eye movement control in reading, which we refer to as “Glenmore”, that can account within one mechanism for preview and spillover effects, and for regressions, progressions, and refixations. The model decouples the decision about when

The interactive activation model of cor. text effects in letter perception is reviewed, elaborated, and tested. According to the model context aids the perception of target letters as they are processed in the perceptual system. The implication that the duration and timing of the context in which a

A model of context effects ii perception is applied to the perception of letters in various contexts. In the moqel, perception results from excitatory and inhibitory interactions of detectors for isual features, letters, and words. A visual input excites detectors for visual features in the display

A snake is an energy-minimizing spline guided by external constraint forces and influenced by image forces that pull it toward features such as lines and edges. Snakes are active contour models: they lock onto nearby edges, localizing them accurately. Scale-space continuation can be used to enlarge

The ability to recognize humans and their activities by vision is key for a machine to interact intelligently and effortlessly with a human-inhabited environment. Because of many potentially important applications, “looking at people ” is currently one of the most active application domains
