This study was designed to explore how adults with autism and Asperger syndrome (ASD) would visually process compound figures. They were tested in two tasks, one involving hierarchical global/local stimuli, the other involving face-like or geometrical stimuli where the processing of the inter-elemental spatial relationships was emphasized. Adults…

The SeLective Attention Model (SLAM) performs visual selective attention tasks and demonstrates that object selection and attribute selection are both necessary and sufficient for visual selection. The SLAM is described, particularly with regard to its ability to represent an individual subject performing filtering tasks. (TJH)

Previous studies have found that an object can be categorized faster at a basic level (hammer) than at either a subordinate (club hammer) or a superordinate level (tool). While some attribute this result to basic categories having more distinctive attributes, other factors might cause this result. For example, basic categories routinely have…

Results of two studies indicate a tendency among young children to impose organization on information encoded in memory and in relation to increases in metric accuracy, decentration, and efficient scanning, which enable them to more accurately evaluate when such organization is and is not appropriate.

Summarizes an initial foray in tackling artificial intelligence problems using a connectionist approach. The task chosen is visual recognition of Origami objects, and the questions answered are how to construct a connectionist network to represent and recognize projected Origami line drawings and the advantages such an approach would have. (30…

A general framework is outlined for describing the relationship of cognition to brain systems. The model provides for empirical investigations at many levels--computational, chronometric, spatial imaging, and cellular--and argues for the logical interrelationship of these areas of investigation. It is applied to selective visual-spatial attention…
