Dizziness of unknown cause may be perception disorder: Perception disorders may throw those affected off balance

Many patients with functional dizziness look back on a long odyssey to numerous doctors, because no organic causes could be found. Now for the first time, an experiment at the Technical University of Munich (TUM) has identified possible causes of the disorder: problems with the processing of sensory-motor signals in the brain that resemble those associated with dizziness due to […]

When a fix for one vision problem causes another

As we age, our eyes lose their ability to focus up close. It’s a condition called presbyopia, and it’s both extremely common and relatively easy to fix, with solutions like reading glasses, bifocals, or progressive lenses. Another common correction, called monovision, solves the problem with different lenses in each eye, one that focuses nearby, the other that focuses far away. […]

Perception and working memory are deeply entangled, study finds

Many people have an intuitive, though incorrect, understanding of how the brain works: Our senses perceive objectively factual data, and our higher-level thought processes interpret that data, pull some levers and shape our conclusions and behavior accordingly. But perception and thought are fundamentally linked, according to research published in Nature Human Behavior last week by Dwight Kravitz, an assistant professor […]

People’s motivations bias how they gather information: A person will gather less data before reaching a conclusion they wished was true all along

A new study suggests people stop gathering evidence earlier when the data supports their desired conclusion than when it supports the conclusion they wish was false. Filip Gesiarz, Donal Cahill and Tali Sharot of University College London, U.K. report in PLOS Computational Biology. Previous studies had already provided some clues that people gather less information before reaching desirable beliefs. For […]

Seeing disfigured faces prompts negative brain and behavior responses: Brain imaging study finds negative implicit biases against individuals with scars, birthmarks and other facial differences

People with attractive faces are often seen as more trustworthy, socially competent, better adjusted, and more capable in school and work. The correlation of attractiveness and positive character traits leads to a “beautiful is good” stereotype. However, little has been understood about the behavioral and neural responses to those with facial abnormalities, such as scars, skin cancers, birthmarks, and other […]
