For many years, to reduce the crash frequency and severity at high-speed signalized intersections, warning flashers have been used to alert drivers of potential traffic-signal changes. Recently, more aggressive countermeasures at such intersections include a speed-limit reduction in addition to warning flashers. While such speed-control strategies have the potential to further improve the crash...

Intuitively, dynamic visual stimuli, such as moving objects or flashing lights, attract attention. Visual search tasks have revealed that dynamic targets among static distractors can indeed efficiently guide attention. The present study shows that the reverse case, a static target among dynamic distractors, allows for relatively efficient selection in certain but not all cases. A static target ...

The temporal interval between flashing lights that is required to perceive nonsimultaneity decreases as the refractive error increases from 0 to +2 diopters. The interval then remains constant with further increases to 3 and 4 diopters. The results are discussed in terms of the relative increase of transient to sustained visual channels and of the increase in apparent movement.

This study examined the effect of sensory feedback (e.g., flashing lights and sound) on the imitation performance of children with autism and typical children group-matched for mental age. Participants were administered an immediate object-imitation task with six novel toys constructed for this study: three with a sensory effect that could be activated by imitating the modeled action and three ...

Acute macular neuroretinopathy is an infrequently encountered condition in which there is a sudden mild central vision loss, photopsia and red-brown wedge-shaped lesions in the macular region with corresponding scotomata in the central visual fields. The condition may be associated with the use of oral contraceptives or with a recent febrile illness. It is self-limiting and non-recurrent. The c...

This article argues that the mid-1960s saw a dramatic shift in how 'brainwashing' was popularly imagined, reflecting Anglo-American developments in the sciences of mind as well as shifts in mass media culture. The 1965 British film The Ipcress File (dir. Sidney J. Furie, starr. Michael Caine) provides a rich case for exploring these interconnections between mind control, mind science and media,...

background: crohn’s disease is an inflammatory bowel disease that can affect any part of the gastrointestinal (gi) tract including the mouth. bowel symptoms are predominant. oral involvement may precede the gi symptoms. this case report presents a patient affected by crohn’s disease with oral onset. case presentation: we present a 30-year-old pregnant woman complaining of chronic, multiple, yel...

tinea capities is the commonest dermatophytosis in children with diverse clinical presentations. the causative fungi of tinea capitis vary with geographic area and time.this study was aimed to identify the etiologic agents and determine the related factors of tinea capitis in tehran, iran. from clinically suspected cases of tinea capitis, microscopy and culture were performed. of 58patients 96%...

"Change-in-support" balance-recovery reactions that involve rapid stepping or reaching movements play a critical role in preventing falls. Recent geriatrics studies have led to new interventions to improve ability to execute these reactions effectively. Some of these interventions have the potential to reduce fall risk for younger persons working in industrial settings. In this paper, we review...
