Connectionism and cognitive architecture: A critical analysis
Abstract This paper explores differences between Connectionist proposals for cognitive architecture and the sorts of models that have traditionally been assumed in cognitive science. We claim thatExpand

Tracking multiple independent targets: evidence for a parallel tracking mechanism.
TLDR
We show that, while certain aspects of attention require that locations be scanned serially, at least one operation may be carried out in parallel across several independent loci in the visual field. Expand

Computation and cognition - toward a foundation for cognitive science
TLDR
The question, "What is Cognitive Science?" is often asked but seldom answered to anyone's satisfaction. Until now, most of the answers have come from the new breed of philosophers of mind. In Computation and Cognition, Pylyshyn argues that computation must not be viewed as just a convenient metaphor for mental activity, but as a literal empirical hypothesis. Expand

The role of location indexes in spatial perception: A sketch of the FINST spatial-index model
This paper hypothesizes a resource-limited mechanism, called a FINST, for individuating or indexing visual features, as distinct from encoding their type or location. FINSTs have the property thatExpand

Although the study of visual perception has made more progress in the past 40 years than any other area of cognitive science, there remain major disagreements as to how closely vision is tied toExpand

Why are small and large numbers enumerated differently? A limited-capacity preattentive stage in vision.
: Subitizing," the process of enumeration when there are fewer than 4 items, is rapid (40-100 ms/item), effortless, and accurate. "Counting," the process of enumeration when there are more than 4Expand

What enumeration studies can show us about spatial attention: evidence for limited capacity preattentive processing.
Subitizing, the enumeration of 1-4 items, is rapid (40-120 ms/item) and accurate. Counting, the enumeration of 5 items or more, is slow (250-350 ms/item) and error-prone. Why are small numbers ofExpand

Visual indexes, preconceptual objects, and situated vision
This paper argues that a theory of situated vision, suited for the dual purposes of object recognition and the control of action, will have to provide something more than a system that constructs aExpand

It is generally accepted that there is something special about reasoning by using mental images. The question of how it is special, however, has never been satisfactorily spelled out, despite moreExpand
