Abstract: A diagnostic method and apparatus facilitating a test for diagnosing attention deficit hyperactivity disorder (ADD/ADHD) in a person is disclosed, which in many embodiments includes a visual problem solving test involving distinctive feature analysis. It facilitates making objective observations of multiple components of attention and executive functioning. This test in some embodiments consists of a 24 individual test items with plates of geometric faces. The test requires the subjects to select two identical faces out a field of faces that progressively increase in number and complexity. The geometric faces could instead be graphic faces, stick figures, geometric shapes or other visual stimuli in other embodiments. Correct/incorrect scores and response times are compared to normative data and coupled with structured behavioral observations to provide objective evidence of the subject's attentional and executive functioning status.
