Patent number: 8696359Abstract: This invention relates to methods and means for assessing cognitive dysfunction, in particular impulsivity associated cognitive dysfunction, which may for example include Attention Deficit Hyperactivity Disorder (ADHD), substance abuse, and non-toxic addictive/compulsive behavior. A method may comprise displaying a population of elements to the individual and allowing the sequential selection of elements within the population by the individual. The selection of an element reveals to the individual a characteristic of the selected element which is one of a number of possible characteristics of elements in said population. The sequential selection ends when the individual chooses which of the possible characteristics is possessed by the most elements in the population. The number of elements selected by the individual in making this choice is then correlated to the likelihood that the individual has impulsivity associated cognitive dysfunction.Type: GrantFiled: July 19, 2004Date of Patent: April 15, 2014Assignee: Cambridge University Technical Services LimitedInventors: Luke Clark, Trevor W. Robbins
