Illusory conjunctions (ICs) provide evidence for a binding problem that must be resolved in vision. Objects that are perceptually grouped are more likely to have their features erroneously conjoined. We examined whether semantic grouping, determined by category membership (letter vs. number), also influences illusory conjunction rates. Participants were instructed to detect an "L" or a "7" amon...

I am deeply honored to receive the ACL’s Lifetime Achievement Award. I’m especially honored when I look back at the list of previous winners—Chuck Fillmore, Eugene Charniak, Eva Hajičová, Fred Jelinek, Martin Kay, Aravind Joshi, and the others— they’re all my heroes. I was of course delighted to learn of this award. The most we can hope for in life is to take part in the conversation, and an aw...

FoIlc Acid Deficiency Folic acid deficiency, the most common nutrient deficiency, may be found in over one-quarter of hospitalized psychiatric patients.' It appears to affect mood by impairing the synthesis of tetrahydrobiopterin (BH4), a cofactor essential for the synthesis of serotonin and other monoamines involved in the pathogenesis of affective disorders.^ One study found that lower plasma...

A learning capacity for feeding is described in many insect species including vectors of diseases, but has never been reported in tsetse flies (Diptera, Glossinidae), the cyclic vectors of human (sleeping sickness) and animal trypanosomoses in Africa. Repeated feeding on the same host species by a disease vector is likely to increase the within-species disease-transmission risk, but to decrease...

This article describes a model for including scene/context priors in attention guidance. In the proposed scheme, visual context information can be available early in the visual processing chain, in order to modulate the saliency of image regions and to provide an efficient short cut for object detection and recognition. The scene is represented by means of a low-dimensional global description o...

Primate visual cortex is hierarchically organized. Bottom-up and top-down influences are exerted through distinct frequency channels, as was recently revealed in macaques by correlating inter-areal influences with laminar anatomical projection patterns. Because this anatomical data cannot be obtained in human subjects, we selected seven homologous macaque and human visual areas, and we correlat...
