This app is developed by neuropsychologist, launched on 2016. It is currently subject of PH. D research. This application is based on neuropsychological models known as “go / no go” and “N-back”
The mechanic of the game is to press the screen in the presence of a specific stimulus, for example: “click when you see a barking dog”. Depending on the block in which user are (vigilance vs. inhibition) he must press the screen seldom_ discriminated between possible distractors and thus maintaining state of alert_ what is known as “vigilance or attention”; Or, on the contrary, we must press many times_ to hold back an automatic response_ what is known as “inhibition or self-control”. It has 60 games distributed in 2 different blocks (vigilance and inhibition) and 2 different levels. Additionally, it is developed to train working memory (in some exercises the user must press the presence of a sequence, for example: “press if you see a 3 after a 6” thus updating the information in its operating memory), and processing speed as well as visual and auditory discrimination given the presence of both types of stimulus, which may appear as a target or as a distractor.
Nexxo has been thought to improve attentional and behavioral processes as well as training with people with attention difficulties (Attention Deficit Disorder and / or Hyperactivity), difficulties in self-control and regulation of behavior, or cognitive impairment (aging and / or dementias). Nexxo allows to evaluate the type of errors committed: commission errors (the user hit the screen when he should not), and, omission errors (the user did not press when he should).
