Abstract: | Changes in subjective median plane (SMP) as a result of asymmetrical visual and bodily stimulation were measured for a total of 260 Ss, age 5–17. Asymmetrical visual stimulation resulted in a readjustment of the SMP in the direction of stimulation, with a decline in magnitude of response as a function of age. Asymmetrical bodily stimulation was assimilated to by the younger children (SMP adjusted in the direction of stimulation), . and counteracted by the older children (age 8 and older). In the combination of the two, the effects of visual stimulation dominated those of bodily stimulation throughout the age range, possibly due to insufficient exposure to the asymmetrical bodily stimulation. Correlational analysis showed that CA, rather than MA, was the major variable associated with the results. The results are in general agreement with sensory-tonic theory, and are discussed in this light. |
