[Systematic basis of analysis of action sequences in a "Binatest" device]

The paper presents a method for analysing and interpreting the results of patients' examination using a Binatest device. The examination was made in the situation of "optional choice" wherein multiple acts of choice from two alternative goal-oriented reactions lead only to positive results. The proposed analysis is based on the evaluation of previous quanta of behavior for further goal formation with limited analysis depth with three sequential events. The paper discusses what information may be derived from the analysis of monads, diads, and triads of step-by-step acts of choice. Four major parameters fit for the analysis and interpretation of the findings have been identified. These include diad asymmetry, runs, left and right stereotypies. Each parameter has its own value that is orthogonal towards the others, equal measurement limits, which are independent of their production, and fully determines the sequence of behavioral quanta at the depth of 3 events. It is shown that basic information on decision-making should be searched in the structure of sequential choice acts made by a patient during his/her examination rather than in the chosen behavioral acts themselves.
