Brain Vascular Disease Overt and Covert

Brain vascular disease overt and covert.

See related article, pages 2116–2120 Work from the Leukoaraiosis and Disability (LADIS) Study Group1 and from others characterizing brain structure and function in the elderly continue to challenge myopic views of how vascular disease affects the brain. What most often demands attention and consumes resources—patients with symptoms and signs of stroke and transient ischemic attack—represents th...

Overt Responses during Covert Orienting

A distributed network of cortical and subcortical brain areas controls our oculomotor behavior. This network includes the superior colliculus (SC), which coordinates an ancient visual grasp reflex via outputs that ramify widely within the brainstem and spinal cord, accessing saccadic and other premotor and autonomic circuits. In this Review, we discuss recent results correlating subliminal SC a...

Overt and Covert Narcissism in Iranian Students: The Role of Self-esteem and Shame

Objective: For decades, both theory and research have focused on the role of self-esteem and shame in constructing narcissistic traits. However, studies on the exact relationship between these two and overt and covert facets of narcissism have been equivocal.  Methods: The current study is correlational. It examined these relationships among 308 Iranian college students (155 males, 153 femal...

The Covert Helps Parse the Overt

This paper is concerned with whether deep syntactic information can help surface parsing, with a particular focus on empty categories. We design new algorithms to produce dependency trees in which empty elements are allowed, and evaluate the impact of information about empty category on parsing overt elements. Such information is helpful to reduce the approximation error in a structured parsing...
