Neuroscience research has examined separately how we detect human agents on the basis of their face and body (person perception) and how we reason about their thoughts, traits or intentions (person knowledge). Neuroanatomically distinct networks have been associated with person perception and person knowledge, but it remains unknown how multiple features of a person (e.g. thin and kind) are lin...

To the Editor: Legionnaires’ disease is an often severe form of pneumonia that is typically acquired by susceptible persons (e.g., elderly persons and smokers) through inhalation of aerosols that contain legionella species.1-4 A cluster of cases of this disease occurred in Vila Franca de Xira, Portugal, in 2014.5 One of the first cases of disease in this cluster occurred in a 48-year-old man (P...

This study explores how children’s drawings, as rated on the Formal Elements Art Therapy Scale (FEATS), are related to their emotional and behavioral health. Participating students (ages 8-16, N=53), attending a therapeutic day school for students with emotional and behavioral disorders, drew a picture of a person picking an apple from a tree (PPAT). A discriminant function analysis indicated t...

With the increasing amount of available multimedia data, efficient systems for searching and retrieving relevant AV documents are needed. Since keyword based indexing is very time consuming and inefficient due to linguistic and semantic ambiguities, content based multimedia retrieval systems have been proposed, that search and retrieve AV documents based on audio and visual features. While cont...

by Jeffrey A. DeMann The article that follows is part of the Schizophrenia Bulletin's ongoing First Person Accounts series. We hope that mental health professionals—the Bulletin's primary audience—will take this opportunity to learn about the issues and difficulties confronted by consumers of mental health care. In addition, we hope that these accounts will give patients and families a better s...

Plague has received much attention because it may be used as a weapon by terrorists. Intentionally released aerosols of Yersinia pestis would cause pneumonic plague. In order to prepare for such an event, it is important, particularly for medical personnel and first responders, to form a realistic idea of the risk of person-to-person spread of infection. Historical accounts and contemporary exp...

We address the problem of detecting human violence in video, such as fist fighting, kicking, hitting with objects, etc. To detect violence we rely on motion trajectory information and on orientation information of a person’s limbs. We define an Acceleration Measure Vector (AMV) composed of direction and magnitude of motion and we define jerk to be the temporal derivative of AMV. We present resu...

A linear phase correction model has been shown to accurately reflect the corrective processes involved in synchronising motor actions to an external rhythmic cue. The model originated from studies of finger tapping to an isochronous metronome beat and is based on the time series of asynchronies between the metronome and corresponding finger tap onsets, along with their associated intervals. Ove...

When determining the cause of a person's behavior, perceivers often overweigh dispositional explanations and underweigh situational explanations, an error known as the Fundamental Attribution Error (FAE). The FAE occurs in part because dispositional explanations are relatively automatic, whereas considering the situation requires additional cognitive effort. Stress is known to impair the prefro...
