[Spatial orientation with regard to short-term memory, age and cerebral dominace]

Though orientation in acoustic space frequently has been the subject of investigations, sound was offered as a rule only in one or two dimensions of the subjective polar system of coordinates. In an earlier paper a test-situation was presented in which the offering of sound is varied in all three dimensions (horizontal and vertical angle as well as distance); the mistake also is calculated in these three dimensions separately. In this paper the investigations are continued by examinating the influence of age, the cerebral dominance and the short-term memory (offering of two different noises with following indication). Our results show that 1) age has no significant influence; 2) the relation of mistakes of the right and the left side is significantly more inhomogen in all three dimensions in left-handed persons; 3) the influence of the memory does not enlarge the mistake significantly.
