Comprehenders can rapidly and efficiently interpret expressions with various types of non-adjacent dependencies. In the sentence The boy that the teacher warned fell, boy is readily interpreted as the subject of the verb fall despite the fact that a relative clause, that the teacher warned, intervenes between the two dependent elements. We review research investigating three memory operations p...

QUERY-DEPENDENT SELECTION OF RETRIEVAL ALTERNATIVES SEPTEMBER 2011 NIRANJAN BALASUBRAMANIAN Ph.D., UNIVERSITY OF MASSACHUSETTS AMHERST Directed by: Professor James Allan The main goal of this thesis is to investigate query-dependent selection of retrieval alternatives for Information Retrieval (IR) systems. Retrieval alternatives include choices in representing queries (query representations), ...

Learning constitutes a fundamental property of the human brain-yet an unresolved puzzle is the profound variability of the learning success between individuals. Here we highlight the relevance of individual ongoing brain states as sources of the learning variability in exposure-based somatosensory perceptual learning. Electroencephalogram recordings of ongoing rhythmic brain activity before and...

This paper proposes a new mixed quantum mechanics (QM)-molecular mechanics (MM) approach, where MM is replaced by quantum Hamilton mechanics (QHM), which inherits the modeling capability of MM, while preserving the state-dependent nature of QM. QHM, a single mechanics playing the roles of QM and MM simultaneously, will be employed here to derive the three-dimensional quantum dynamics of diatomi...

Frontal and parietal asymmetries have repeatedly been shown to be related to specific functional mechanisms involved in emotion regulation. From a developmental perspective, attachment representations based on experiences with the caregiver are theorized to serve regulatory functions and influence how individuals deal with emotionally challenging situations throughout the life span. This study ...

Editors’ Note: Commenting on “The magnetic apraxia of Denny-Brown,” Dr. Hassan points out that magnetic apraxia is related to frontal lobe lesion and not parietal lobe dysfunction as suggested in the text. Dr. Peluso, author of the Video NeuroImage, acknowledges the mistake and a correction appears on page 1483. In response to “Mechanisms of memory impairment in epilepsy depend on age at diseas...

The temporal dynamics and anatomical correlates underlying human visual cognition are traditionally assessed as a function of stimulus properties and task demands. Any non-stimulus related activity is commonly dismissed as noise and eliminated to extract an evoked signal that is only a small fraction of the magnitude of the measured signal. We review studies that challenge this view by showing ...
