A. R. Luriya's credo
To nail to the door

Posted on Conductive World a year ago, and too precious not to be posted again 
  1. There are higher cortical (or psychological) functions specific to human being[s] and not existing in animals...
  2. The most specific features of these higher processes is that they are tool- or means-using processes. Animals do not use means, their behavior is not mediated by means, tools or signs...
  3. This indirect, means-using behavior is mediated via speech – this most important system of tools or signs in human history...
  4. The indirect tool (sign)-using behavior starts a new form of cortical work: the human cortex [becomes] a historically organized, plastic functional system where language plays a decisive organizing role...
  5. The disorganization of brain functions following local brain lesions is in no way a partial deficit... and no more a total lowering of the general brain activity. It results in a disorganization of functional brain systems resulting from a deficit of a basic factor according to locus of the lesion) – bringing a series of primary symptoms and resulting in a series of secondary symptoms or functional ('systemic') results.
  6. The basic goal of neuropsychology is... a careful psychological qualification of the symptom (i.e. singling out the underlying factor, and then – a description of systemic results of the destruction or elimination of this factor); that is the real way to the neuropsychological diagnostics of brain injury.
