Determining random responding for the category, speech-sounds perception, and Seashore Rhythm tests.
A formula is presented for determining if scores from the Category, Speech-Sounds Perception, and Seashore Rhythm tests are significantly different from random responding. Confidence intervals for random responding are also presented. Results of published studies involving normative and non-normal subjects are reviewed, and the percentage of subjects responding in the random range are presented. Normative subjects' scores on the Category and Speech-Sounds Perception tests do not fall into the random range, but high percentages of their Seashore Rhythm Test scores do fall into the random range.
