A selective impairment of motion perception following lesions of the middle temporal visual area (MT)
- JOURNAL OF NEUROSCIENCE
, 1988
"... Physiological experiments indicate that the middle temporal visual area (MT) of primates plays a prominent role in the cortical analysis of visual motion. We investigated the role of MT in visual perception by examining the effect of chemical lesions of MT on psychophysical thresholds. We trained rh ..."

intensity for which the monkey could successfully complete a direction discrimination. In the contrast task, we measured the threshold contrast for which the monkeys could successfully discriminate the orientation of stationary gratings. Injections of ibotenic acid into MT caused striking elevations

contribution to current global warming, after carbon dioxide emissions. In the Himalayan region, solar heating from black carbon at high elevations may be just as important as carbon dioxide in the melting of snowpacks and glaciers. The interception of solar radiation by atmospheric brown clouds leads
Storage of spatially specific threshold elevation
- Perception
, 1978
"... Abstract. The decay of several visual aftereffects may be prolonged by interposing a period of light-free or pattern-free viewing between adaptation and testing. We demonstrate that this storage phenomenon can be observed using the threshold elevation aftereffect that follows inspection of a high-co ..."

Repetition blindness: Type recognition without token individuation
- Cognition
, 1987
"... Three experiments are described which use RSVP (rapid serial visual presentation) to demonstrate a new cognitive phenomenon called “repetition blindness”. Subjects have difficulty detecting repeated words-even when the two occurrences are nonconsecutive and differ in case (Experiment 1). In immediat ..."

). In immediate verbatim recall of sentences (Experiment 2), subjects selectively omitted second instances of repeated words, sacrificing the meaning and grammaticality of the sentence. In Experiment 3, recognition threshold for the last word in a list was lowered, not elevated, when that word had also occurred
Spatial frequency adaptation: threshold elevation and perceived contrast
- Vision Research
, 1996
"... We have measured the spread of contrast adaptation across the dimension of spatial frequency. Threshold elevation was tightly tuned to the adapting spatial frequency but became much broader as test contrast was increased. This means that, for a given test frequency, there arc some frequencies which ..."

Thresholds for warming-induced growth decline at elevational tree line
- in the Yukon Territory, Canada. Global Biogeochemical Cycles
, 2004
"... [1] A few tree ring studies indicate recent growth declines at northern latitudes. The precise causes are not well understood. Here we identify a temperature threshold for decline in a tree ring record from a well-established temperature-sensitive site at elevational tree line in northwestern Canada ..."

Original Article Performance of Music Elevates Pain Threshold and Positive Affect:
"... Abstract: It is well known that music arouses emotional responses. In addition, it has long been thought to play an important role in creating a sense of community, especially in small scale societies. One mechanism by which it might do this is through the endorphin system, and there is evidence to ..."

to support this claim. Using pain threshold as an assay for CNS endorphin release, we ask whether it is the auditory perception of music that triggers this effect or the active performance of music. We show that singing, dancing and drumming all trigger endorphin release (indexed by an increase in post

Threshold Selection, Hypothesis Tests, and DOE Methods

Theoretical results are presented and applied to a simple model of stochastic search and to a simplified elevator simulator. Design of experiments methods are used ..."

Distance Threshold for the Effect of Urban Agriculture
- on Elevated Self-Reported Malaria Prevalence in Accra, Ghana.‖American Journal of Tropical Medicine and Hygiene 80(4

Previous studies have not identified a variable distance effect on malaria prevalence from UA. This study exa ..."

The odds of self-reported malaria are significantly higher for women living within 1 km of UA compared with all women living near an irrigation source, the association disappearing beyond this critical distance. Malaria prevalence is often elevated in communities within 1 km of UA despite more
