The following criteria are required to classify an event as an inattentional blindness episode: 1) the observer must fail to notice a visual object or event, 2) the object or event must be fully visible, 3) observers must be able to readily identify the object if they are consciously perceiving it, [3] and 4) the event must be unexpected and the failure to see the object or event must be due ...
Attention is manifested by an attentional bottleneck, in terms of the amount of data the brain can process each second; for example, in human vision, less than 1% of the visual input data stream of 1MByte/sec can enter the bottleneck, [4] [5] leading to inattentional blindness.
The 'predominantly inattentive presentation' is similar to the other presentations of ADHD except that it is characterized predominately by symptoms of inattention, such as poor sustained attention, procrastination, hesitation, and forgetfulness. It differs in having fewer or no typical symptoms of hyperactivity or impulsiveness.
Attention deficit hyperactivity disorder (ADHD) [1] is a neurodevelopmental disorder characterized by executive dysfunction occasioning symptoms of inattention, hyperactivity, impulsivity and emotional dysregulation that are excessive and pervasive, impairing in multiple contexts, and developmentally-inappropriate.
This is due to the mechanisms of inattentional blindness and inattentional amnesia that cause a lack of semantic processing, compromising incidental memory. [12] These phenomenas are a byproduct of selective attention, where individuals with their attention occupied fail to notice or recall salient or frequently encountered information deemed ...
A study explains why brains can only process a little visual information at a time, what researchers call "normal blindness." It can leads to missing typos. Normal blindness: New study explains ...
Low attentional control is more common among those with attention deficit hyperactivity disorder (ADHD), "a disorder with persistent age-inappropriate symptoms of inattention, hyperactivity, and impulsivity that are sufficient to cause impairment in major life activities". [27]
Variations of the Posner cueing task have been used in many studies to assess the effect of focal damage or disorders on attentional ability as well as to better understand spatial attention in healthy people. The following findings are only a few of the many results that have been established through the use of the Posner cueing task:
