Visual search and stimulus similarity.
A new theory of search and visual attention is presented, which accounts for harmful effects of nontargets resembling any possible target, the importance of local nontarget grouping, and many other findings.
Visual marking: prioritizing selection for new objects by top-down attentional inhibition of old objects.
The authors propose a new mechanism for prioritizing the selection of new events: visual marking and discusses the relations between marking and other accounts of visual selection and potential neurophysiological mechanisms.
Early, involuntary top-down guidance of attention from working memory.

The results suggest that there can be early, involuntary top-down directing of attention to a stimulus matching the contents of working memory.
Perceptual effects of social salience: evidence from self-prioritization effects on perceptual matching.
The results indicate that associating a stimulus to the self modulates its subsequent perceptual processing, and this may operate by self-associated shapes automatically evoking the reward system.
Cascade processes in picture identification
This work presents evidence drawn from both normal observers and from a patient that the effect of structural and semantic similarity between objects on picture naming should be confined to the process of accessing semantic knowledge.

Hierarchies, similarity, and interactivity in object recognition: “Category-specific” neuropsychological deficits
The evidence on category-specific impairments is reviewed, arguing that deficits even for one class of object cannot be accounted for in terms of a single information processing disorder across all patients; problems arise at contrasting loci in different patients.
Systematic analysis of deficits in visual attention.

The authors develop systematic methods for analyzing such impairments in terms of Bundesen's (1990) Theory of Visual Attention and apply these in a group of 9 patients with parietal lobe lesions and variable spatial neglect, showing how differentiation of attentional impairments can be informed by a theory of normal function.
The Effects of Surface Detail on Object Categorization and Naming
The results suggest that surface details can affect object recognition and naming, depending upon: (1) the degree to which objects must be differentiated for a correct response to be made, and (2) the nature of the rate-limiting process determining performance.
