We examined the degree of lead exposure, based on tissue-lead concentrations, in 184 raptors of 16 species found dead across Canada. The most prevalent species available for examination were Red-tailed hawks, Great horned owls, and Golden eagles (n = 131). The majority of individuals examined had very low lead accumulation, however 3-4% of total mortality(More)
This paper contrasts three different schemes of reference relevant to understanding systems of perceptual representation: a location-based system dubbed "feature-placing", a system of "visual indices" referring to things called "proto-objects", and the full sortal-based individuation allowed by a natural language. The first three sections summarize some of(More)
I am very grateful to my commentators for their interest and their careful attention to A Theory of Sentience. It is particularly gratifying to find other philosophers attracted to the murky domain of preattentive sensory processing, an obscure place where exciting stuff happens. I can by no means answer all of their objections or counterarguments, and some(More)
Modularity theorists have challenged that there are, or could be, general learning mechanisms that explain theory-of-mind development. In response, supporters of the ‘scientific theory-theory’ account of theory-of-mind development have appealed to children’s use of auxiliary hypotheses and probabilistic causal modeling. This article argues that these(More)
Experiments on cuing have long provided insights into the mechanisms of selective attention. A visual cue presented in a particular location can enhance subsequent visual discriminations at that location, making them faster, or more accurate, or both. The standard interpretation of such experiments is that the cue attracts attention. Subsequent stimuli at(More)
One of the biggest challenges in understanding perception is to understand how the nervous system manages to integrate the multiple codes it uses to represent features in multiple sensory modalities. From different cortical areas, which might separately register the sight of something red and the touch of something smooth, one effortlessly generates the(More)
