  • Studies that require participants to carry out attention-demanding tasks under conditions of high distraction reveal how unpleasant a mentally fatigued person can be. (wikipedia.org)
  • Fatigue that is experienced by participants of these kinds of studies is induced by attention-intensive tasks, and the observed effects of such fatigue are correlated with decline in inhibitory control. (wikipedia.org)

  • illness
  • Any illness or injury to the brain that interrupts the brain circuits involved in maintaining attention and inhibiting external stimuli may also contribute to the development of directed attention fatigue. (wikipedia.org)
  • stimuli
  • The greatest threat to a given focus of attention is competition from other stimuli that can cause a shift in focus. (wikipedia.org)
  • page needed] Directed attention fatigue occurs when a particular part of the brain's global inhibitory system is overworked due to the suppression of increasing numbers of stimuli. (wikipedia.org)
  • This type of attention employs the inhibitory mechanisms of the brain, which help block incoming stimuli that are unrelated to the task at hand. (wikipedia.org)
  • studies
  • Some fMRI studies have shown that directed attention involves changes in the anterior cingulate cortex and the lateral prefrontal cortex, perhaps as a consequence of increased connectivity between these two areas. (wikipedia.org)
  • Environment
  • Activities that engage this system include multitasking, working in an environment with disruptive background noise or after a lack of sleep, and rapidly changing focus during a prolonged period of attention. (wikipedia.org)
  • Since the number of possible sources of information in the environment is so great, attention, which selectively directs and concentrates awareness and controls input, is of the first importance. (thefreedictionary.com)
  • brain
  • Brain Imaging and Behavior. (monash.edu)
  • Several parts of the brain are involved in maintaining directed attention, primarily those located in the frontal lobe and the parietal lobe of the brain. (wikipedia.org)
  • Specifically, the mechanism of directed attention employs the prefrontal cortex (PFC), the anterior cingulate cortex (ACC) and the brain stem's basal ganglia. (wikipedia.org)
  • Attention can be objectively demonstrated by such methods as electro-encephalography or PET scanning, which show special activity in the parts of the brain most employed at the time. (thefreedictionary.com)
  • condition
  • The condition can be difficult to tell apart from other disorders, as well as to distinguish from high levels of activity that are still within the normal-range. (wikipedia.org)
  • development
  • Regarding exposure to PBDEs, lower mental development, psychomotor development and IQ were found at preschool age, and poorer attention at school age. (springer.com)
  • outcomes
  • Some postulate that the chronic stress documented to occur in some communities near hazardous waste sites could possibly lead to an array of biopsychosocial effects, including physical health effects from chronic stress (possible health outcomes affected by stress include cardiovascular, gastrointestinal disorders, and skin), increases in the prevalence of certain psychological disorders, and social disruption. (cdc.gov)
  • symptoms
  • Due to the many possible combinations of symptoms, there is debate about whether the diagnosis represents a single disorder or a number of discrete syndromes. (pschitt.info)

  • Studies that require participants to carry out attention-demanding tasks under conditions of high distraction reveal how unpleasant a mentally fatigued person can be. (wikipedia.org)
  • onset
  • The onset of directed attention fatigue can be triggered by a number of activities, all of which involve use of the brain's inhibitory system. (wikipedia.org)
  • Genetic
  • Family studies indicate that the closer a person's genetic relatedness to a person with schizophrenia, the greater the likelihood of developing the disorder. (wikipedia.org)
