Background: Gestational diabetes (GA) is a common complication, associated with adverse prenatal outcomes and perceived stress. The effects of education on perceived stress have been widely investigated, whereas the role of self-care in GA has been less noted. Aim: to determine the effects of self-care education on perceived stress in women with GA under insulin treatment. Methods: In this rand...

We showed that there is an intensity aspect to the octave illusion in addition to the pitch and location aspects originally reported by Deutsch (1974). In Experiment 1, we asked participants to directly compare the stimulus giving rise to the illusion (ILLU) with one mimicking its most commonly reported percept (illusion consistent; IC) and showed that they were easily able to distinguish betwe...

We investigated whether center-surround interactions affect perceived speed in a manner similar to their effects on direction discrimination thresholds [e.g. Tadin, D., Lappin, J. S., Gilroy, L. A., & Blake, R. (2003). Perceptual consequences of center-surround antagonism in visual motion processing. Nature, 424, 312-315]. Observers were asked to match the speed of a test stimulus (a grating, w...

Binocular disparity is a powerful cue for the perception of depth. The accuracy with which observers can judge depth from disparity can, however, be very poor. This has been attributed to difficulties associated with the scaling of disparity to take account of distance (Johnston, 1991). We test potential strategies that could be used to improve this scaling. Using the depth-to-width ratio task ...

This study demonstrates that a perceptual illusion that alters the perceived length of two lines also affects spatial attention. We used a cuing method that was introduced to study spaceversus object-based attention. Two parallel lines of equal length were placed so that the distance between them was equal to the length of the lines. We then added a scene with depth cues to produce a strong ill...
