Stimulation of one sensory modality can induce perceptual experiences in another modality that reflect synaesthetic correspondences among different dimensions of sensory experience. In visual-hearing synaesthesia, for example, higher pitched sounds induce visual images that are brighter, smaller, higher in space, and sharper than those induced by lower(More)
Nine month old infants search correctly for an object which they have seen hidden in one position, but cease to do so after they have been moved to the opposite side of the display, searching instead at a position which is apparently defined egocentrically from their experience before movement. This error can be explained on the one hand in terms of(More)
Filling in the gaps in what humans see is a fundamental perceptual skill, but little is known about the developmental origins of occlusion perception. Three experiments were conducted with infants between 2 and 6 months of age to investigate perception of the continuity of an object trajectory that was briefly occluded. The pattern of results across(More)
When viewing an event in which an object moves behind an occluder on part of its trajectory, 4-month-old infants perceive the trajectory as continuous only when time or distance out of sight is short. Little is known, however, about the conditions under which young infants perceive trajectories to be discontinuous. In the present studies we focus first on(More)
The ribosome-inactivating protein saporin, from Saponaria officinalis, was coupled by a disulfide bond to monoclonal anti-Thy 1.1 antibody (OX7) and to its F(ab')2 fragment. The immunotoxins were at least as toxic as the plant toxin ricin to the Thy 1.1-expressing cell lines AKR-A and BW5147 in tissue culture. They reduced the rate at which the cells(More)
Previous research has suggested both links and differences between children's copying of line diagrams and their drawings of solid objects. If the diagram represents a familiar object, children make more errors than when copying a diagram of a nonobject or unfamiliar object, as if they are drawing from their representation of the object rather than copying(More)
Cohen (1988; Cohen & Younger, 1984) has suggested that there is a shift in the perception of form sometime after 6 weeks of age. Prior to this age infants can remember the specific orientations of line segments, but cannot process and remember the angular relations that line segments can make. Experiment 1 used simple line stimuli with newborn infants to(More)
To investigate the frequency of oseltamivir resistance in circulating strains of the 2009 influenza A(H1N1) pandemic virus in Scotland, 1,802 samples from 1,608 infected hospitalised patients were screened by the H275Y discriminatory RT-PCR. Among these, we identified 10 patients who developed the H275Y mutation. All of them were immunocompromised and were(More)
Treatment of comorbid posttraumatic stress disorder (PTSD) and opioid dependence has been a challenge for many clinicians. There are limited evidence-based guidelines for treatment of this comorbidity. Symptoms of PTSD and opiate dependence may converge, and it is sometimes difficult to differentiate between both conditions. For example, opioid withdrawal(More)
