[Scaling of disturbances of attention in neurological patients (author's transl)].

In a previous report two additive scales were developed for measuring susceptibility to stimulation (with 4 experimental stimuli) and reactivity (with 4 types of reactions). The degree of loss of attention in neurological patients as determined by the position of a patient correlates with the frequencies of his reactions. Thus the measurement of frequencies does not add any further information. There is no patterning of reactions due to the different etiology of the disorder of attention. These results support the suggested one-factor theory of attention.
