In 1965 two freshly minted linguistic anthropology Ph. Ds were chatting about their recent respective fieldwork experiences, one in Chiapas, Mexico, among speakers of the Mayan language Tzeltal the ot...
Electrophysiological evidence for the left-lateralized effect of language on preattentive categorical perception of color
lateralization Whorfian
2015/6/24
Previous studies have shown that the effect of language on categorical perception of color is stronger when stimuli are presented in the right visual field than in the left. To examine whether this la...
Language regions of brain are operative in color perception
functional magnetic resonance imaging (fMRI) lateralization
2015/6/24
The effect of language on the categorical perception of color is stronger for stimuli in the right visual field (RVF) than in the left visual field, but the neural correlates of the behavioral RVF adv...
Lateralization of categorical perception of color changes with color term acquisition
visual field color perception
2015/6/24
Categorical perception (CP) of color is the faster and more accurate discrimination of two colors from different categories than two colors from the same category, even when same- and differentcategor...
Language affects patterns of brain activation associated with perceptual decision
color neuroimaging linguistic relativity lateralization Whorf
2015/6/24
Well over half a century ago, Benjamin Lee Whorf [Carroll JB (1956) Language, Thought, and Reality: Selected Writings of Benjamin Lee Whorf (MIT Press, Cambridge, MA)] proposed that language affects p...
Further evidence that Whorfian effects are stronger in the right visual field than the left
color categories hemispheric lateralization linguistic relativity visual search
2015/6/24
The Whorf hypothesis holds that differences between languages induce differences in perception and/or cognition in their speakers. Much of the experimental work pursuing this idea has focused on the d...
Whorf hypothesis is supported in the right visual field but not the left
categorical perception color hemispheric laterality linguistic relativity
2015/6/24
The question of whether language affects perception has been debated largely on the basis of cross-language data, without considering the functional organization of the brain. The nature of this neura...
Perhaps the central problem in understanding color appearance is that the only available measures are subjective. Much is now known about the neural mechanisms underlying the early encoding of color i...
Color naming, lens aging, and grue: What the optics of the aging eye can teach us about color language
Color naming lens aging grue aging eye color language
2015/6/24
Many languages without separate terms for “green” and “blue” are or were spoken in locations receiving above-average exposure to ultraviolet-B (UV-B) radiation. Lindsey and Brown (2002) propose that t...
Integration of Sensory and Reward Information during Perceptual Decision-Making in Lateral Intraparietal Cortex (LIP) of the Macaque Monkey
Sensory and Reward Information Perceptual Decision-Making Lateral Intraparietal Cortex Macaque Monkey
2015/6/23
Single neurons in cortical area LIP are known to carry information relevant to both sensory and value-based decisions that are reported by eye movements. It is not known, however, how sensory and valu...
Using time-varying evidence to test models of decision dynamics:bounded diffusion vs.the leaky competing accumulator model
bounded diffusion LCA perceptual choice non-stationary evidence order effects
2015/6/23
When people make decisions, do they give equal weight to evidence arriving at different times? A recent study (Kiani et al., 2008) using brief motion pulses (superimposed on a random moving dot displa...
A neurocomputational approach to obsessive-compulsive disorder
neurocomputational approach obsessive-compulsive disorder
2015/6/23
A recent article shows that a change in a single parameter in a neural-network model of brain dynamics leads to repetitive behaviors that resist termination and towards which the network tends. These ...
Why Bilateral Damage Is Worse than Unilateral Damage to the Brain
Bilateral Damage Unilateral Damage Brain
2015/6/23
Human and animal lesion studies have shown that behavior can be catastrophically impaired after bilateral lesions but that unilateral damage often produces little or no effect, even controlling for le...
Response to McQueen et al.:Theoretical and empirical arguments support interactive processing
McQueen Theoretical empirical arguments interactive processing
2015/6/19
McQueen et al. [1] continue to argue against interactive processes in speech perception, but we suggest that their arguments are unconvincing. Theoretical and empirical arguments support the interacti...
A homeostatic rule for inhibitory synapses promotes temporal sharpening and cortical reorganization
experience interneurons learning computational neuroscience
2015/6/19
Experience with transient stimuli leads to stronger neural responses that also rise and fall more sharply in time. This sharpening enhances the processing of transients and may be especially relevant ...
