A study by Johns Hopkins University suggests that cell phones and driving don't mix because directing attention to listening effectively 'turns down the volume' on visual input. Brain activity recordings show that attention is strictly limited, affecting both auditory and visual tasks.
A study by Washington University postdoctoral fellow Alan Castel found that expert video game players exhibit a 20% reduction in response times compared to non-players. This suggests that expertise is acquired through practice rather than being an innate ability.
The study found that when subjects focus on one feature, they also attend to similar features elsewhere in the visual field. The researchers developed an experimental technique to measure this phenomenon and its implications for understanding how our brain processes visual information.
Researchers found that birds, including domestic chicks and pigeons, show a leftward bias in pecking at grains, similar to human spatial hemineglect. This finding suggests that brain organization underlying attention asymmetries may offer benefits in spatial learning and tasks.
Researchers found that recognizing faces requires visual perception, while lower-level aspects like orientation can be processed without awareness. The study used binocular rivalry experiments and inattentional blindness to demonstrate the importance of visual processing in face recognition.
Researchers found that people can pay attention to multiple stimuli simultaneously, challenging the traditional 'spotlight of attention' model. This discovery has implications for understanding attention-deficit conditions like autism and ADHD.
Researchers at Dartmouth College found that visual attention is specifically drawn to graspable objects, such as tools, and that this effect is more pronounced when these objects are on the right side. This discovery suggests a clear association between visual perception and motor systems in the brain.
Nicotine enhances activation in posterior cortical and subcortical regions of the brain, improving attention in smokers. The study found that nicotine helps focus attention on task demands by shifting cognitive resources from less used parts of the brain.
A recent brain mapping experiment provides significant new support for the theory that attention is the glue that cements visual information together, helping to solve the 'binding problem' in neuroscience. The study found increased activity in the parietal region when individuals were presented with multiple objects at once.
Researchers at Ohio State University found that pilots can detect changes in automation status more effectively when receiving vibrations than visual cues. The study suggests that tactile feedback could be a powerful tool for human-machine communication in various domains, including aviation, healthcare, and space exploration.
Researchers tested human subjects with fMRI scans to show that focusing attention on a single stimulus cancels out suppressive influences of nearby stimuli, improving information processing. This effect is observed in the object vision circuit and is enhanced by spatially directed attention.
Researchers identified specific aspects of attention that help predict driving performance in individuals with Alzheimer's disease. Those who scored poorly on attention tests also performed poorly on driving tests, highlighting the importance of attentional control in driving.
Researchers from the University of Washington have developed a reproducible method demonstrating that subliminal messages can influence human cognition. The technique, called the response window technique, uses a brief flicker of time to test unconscious cognition on over 300 volunteer subjects.
