Right-hand digits: study reveals new visual distortion effect
The amount of the discount may be less important than the numerical value of the farthest right digit, explains a new study from the Journal of Consumer Research. Keith S. Coulter (Clark University) and Robin A. Coulter (University of Connecticut) are the first to identify a visual distortion effect that may influence how consumers look at sale... view more...

Study Suggests Buddhist Deity Meditation Temporarily Augments Visuospatial Abilities
Meditation has been practiced for centuries, as a way to calm the soul and bring about inner peace. According to a new study in Psychological Science, a journal of the Association for Psychological Science, there is now evidence that a specific method of meditation may temporarily boost our visuospatial abilities (for example, the ability to... view more...

Cortical plasticity: it's time to get excited about inhibition
Research from Brandeis University published online this week in Nature offers new insight into how neural circuits are shaped by experience. The article provides new evidence for the mechanisms that affect the ability of the visual cortex to plastically rearrange itself following periods of visual deprivation. view more (2006-08-24)
Adult brain can change, study confirms
It is well established that a child's brain has a remarkable capacity for change, but controversy continues about the extent to which such plasticity exists in the adult human primary sensory cortex. view more (2007-09-06)
Infrared system helps pilots and drivers see in fog and at night
A European research project has developed a prototype infrared-camera system that substantially enhances human visual perception in poor visibility conditions such as fog, heavy rain and at night. view more (2006-05-04)
Visual Learners Convert Words to Pictures in the Brain And Vice Versa, Says Penn Psychology Study
A University of Pennsylvania psychology study, using functional magnetic resonance imaging technology to scan the brain, reveals that people who consider themselves visual learners, as opposed to verbal learners, have a tendency to convert linguistically presented information into a visual mental representation. view more (2009-03-25)
Wired for sound: How the brain senses visual illusions
In a study that could help reveal how illusions are produced in the brain's visual cortex, researchers at the UCSD School of Medicine have found new evidence of rapid integration of auditory and visual sensations in the brain. view more (2007-04-12)
Working memory retains visual details despite distractions
The ability to retain memory about the details of a natural scene is unaffected by the distraction of another activity and this information is retained in "working memory". view more (2006-01-20)
Our visual system may react more rapidly when visualising 2 objects which might collide
International research co-led by professor Alejandro Maiche, of the Department of Basic, Evolutionary and Educational Psychology at the UAB, has put forward the hypothesis that the brain responds to the possibility that two objects might collide, in a different way to how it would react to two objects in movement with divergent trajectories. view more (2007-09-14)
Experimental treatments restore partial vision to blind people
Two experimental treatments, a retinal prosthesis and fetal tissue transplant, restored some vision to people with blinding eye diseases. The findings, presented at Neuroscience 2009, the annual meeting of the Society for Neuroscience and the world's largest source of emerging news on brain science and health, may lead to new treatments for the... view more...

Hidden cues that make smokers light up
Smokers trying to kick the habit for 2004 are probably finding it much harder than they expected. New research by University of Sussex psychologists reveals that smokers subconsciously react to all sorts of visual cues that encourage them to light up. It's not just the obvious sight or smell of a cigarette that sparks off the behaviour. The... view more... (2004-01-14)
How the brain copes with shifty eyeballs
Neurobiologists have pinpointed brain regions critical to one of the brain's more remarkable feats—piecing together a continuous view of the world by integrating snippets of visual input from constantly moving eyes. view more (2007-04-19)
Schizophrenia: Delusion without illusion
Scientists have discovered that schizophrenia sufferers are not fooled by a visual illusion and are able to judge it more accurately than non-schizophrenic observers. view more (2005-10-25)
Despite darkness, nocturnal bees learn visual landmarks while foraging at night
Day-active bees, such as the honeybee, are well known for using visual landmarks to locate a favoured patch of flowers, and to find their way home again to their hive. Researchers have now found that nocturnal bees can do the same thing, despite experiencing light intensities that are more than 100 million times dimmer than daylight. The new... view more...

Test allows early detection of vision problems in infants with hemangiomas of eyelids
In children with vascular birthmarks around the eye, even partial blockage of vision can lead to visual loss due to amblyopia. view more (2009-04-01)
As robots learn to imitate
Can robots learn to communicate by studying and imitating humans' gestures? That's what MIRROR's researchers aimed to find out by studying how infants and monkeys learn complex acts such as grasping and transferring it to robots. view more (2004-12-22)
Violent Video Games Can Improve Vision
Video killed the radio star, the old song goes - but violent video games, a new Tel Aviv University study finds, can also improve the real-world vision of teens who play them. view more (2009-04-08)
Can we 'learn to see?': Study shows perception of invisible stimuli improves with training
Although we assume we can see everything in our field of vision, the brain actually picks and chooses the stimuli that come into our consciousness. view more (2009-10-22)
Monkeys' calls - the beginnings of human language?
Rhesus macaques communicate between themselves using a complex series of sounds that can signify things as distinct as the presence of danger, particular social relationships, emotions or food alerts. Now scientists in the latest issue of Proceedings of the National Academy of Sciences of the United States of America, while analyzing the brain... view more... (2004-12-17)
Perceptual learning relies on local motion signals to learn global motion
Researchers have long known of the brain's ability to learn based on visual motion input, and a recent study has uncovered more insight into where the learning occurs. view more (2009-09-22)
