Selective adaptation to noxious foods
feeding by herbivorous insects. Some of these noxious compounds are both unpalatable and toxic, while others are merely unpalatable or toxic (Bernays and Chapman, 1987; Chapman and Sword, 1994; Glendinning, 1996; Harley and Thorsteinson, 1967). Because many plants concentrate noxious compounds in their most nutritious tissues (McKey, 1979), herbivores would benefit from an ability to adapt to f...
متن کاملSelective adaptation in networks of cortical neurons.
A key property of neural systems is their ability to adapt selectively to stimuli with different features. Using multisite electrical recordings from networks of cortical neurons developing ex vivo, we show that neurons adapt selectively to different stimuli invading the network. We focus on selective adaptation to frequent and rare stimuli; networks were stimulated at two sites with two differ...
متن کاملFitness and the selective adaptation of language
The question that is at the centre of this paper is how can we go about explaining the observed constraints on variation across languages — in other words, language universals.1 What makes many of these constraints interesting is that they appear to have ‘evolved’ in that they are adaptive; a point that is made repeatedly in the functionalist literature. What I will argue here, however, is that...
متن کاملSelective Adaptation of Linguistic Feature Detectors1
Using a selective adaptation procedure, evidence was obtained for the existence of linguistic feature detectors, analogous to visual feature detectors. These detectors are each sensitive to a restricted range of voice onset times, the physical continuum underlying the perceived phonetic distinctions between voiced and voiceless stop consonants. The sensitivity of a particular detector can be re...
متن کاملPerceptual adaptation of vowels generalizes across the phonology and doesn ’ t require local context
Listeners usually understand without difficulty even speech that sounds atypical. When they encounter non-canonical realizations of speech sounds, listeners can make short-term adjustments of their long-term representations of those sounds. Previous research, focusing mostly on adaptation in consonants, has suggested that for perceptual adaptation to take place some local cues (lexical, phonota...
