Functional heterogeneity in posterior parietal cortex across attention and episodic memory retrieval.
While attention is critical for event memory, debate has arisen regarding the extent to which posterior parietal cortex (PPC) activation during episodic retrieval reflects engagement of PPC-mediated… Expand
Second-order motion shifts perceived position
Many studies have documented that first-order motion influences perceived position. Here, we show that second-order (contrast defined) motion influences the perceived positions of stationary objects… Expand
Holistic crowding: selective interference between configural representations of faces in crowded scenes.
It is difficult to recognize an object that falls in the peripheral visual field; it is even more difficult when there are other objects surrounding it. This effect, known as crowding, could be due… Expand
Spatial attention improves reliability of fMRI retinotopic mapping signals in occipital and parietal cortex
Spatial attention improves visual perception and increases the amplitude of neural responses in visual cortex. In addition, spatial attention tasks and fMRI have been used to discover topographic… Expand
Stressor tolerance values for benthic macroinvertebrates in Mississippi
Conceptually, tolerance values represent the relative capacity of aquatic organisms to survive and reproduce in the presence of known levels of stressors. Operationally, they represent the relative… Expand

The free-flowing Clinch and Powell watershed in Virginia, USA, harbors a high number of endemic mussel and fish species but they are declining or going extinct at an alarming rate. To prioritize… Expand
Position shifts following crowded second-order motion adaptation reveal processing of local and global motion without awareness.
Adaptation to first-order (luminance defined) motion produces not only a motion aftereffect but also a position aftereffect, in which a target pattern's perceived location is shifted opposite the… Expand
Assessment Tools for Urban Catchments: Defining Observable Biological Potential
: Urbanization represents a strong and increasingly more prevalent impact on stream quality worldwide. One of the characteristic effects of increased urbanization is a consistent decline in… Expand

Endogenous visual spatial attention improves perception and enhances neural responses to visual stimuli at attended locations. Although many aspects of visual processing differ significantly between… Expand
Shared attentional resources for global and local motion processing.
One of the most important aspects of visual attention is its flexibility; our attentional "window" can be tuned to different spatial scales, allowing us to perceive large-scale global patterns and… Expand
