Document Summary

Allocation of cognitive resources to external or internal stimuli. What is attention: conscious process consciously focusing your attention to a task, unconscious focusing on something without necessarily trying to. Sustained attention: constantly focusing on a task for a long period of time (10 minutes, continuous performance task used to assess attention issues. Divided attention: two or more tasks at the same time, allocating your attentional resources to more than one task. Selective attention: too many stimuli, focusing all your attention to only one or two stimuli. Prevalence: boys usually diagnosed before girls, different networks in the brain that are responsible for different kinds of attention, orienting, alerting and executive networks working together to make this attention. World wide prevalence is 5. 2 % (polanczyk et al. , 2007) happen. Before age 7: problematic because symptoms generally start before age 7 but they can start before or after, more than just lack of attention that defines adhd.
