INSTRUCTIONS FOR YEAR VI
VI, 1. Distinguishing right and left
Procedure. Say to the child: “Show me your right hand.” After this is responded to, say: “Show me your left ear.” Then: “Show me your right eye.” Stress the words left and ear rather strongly and equally; also right and eye. If there is one error, repeat the test, this time with left hand, right ear, and left eye. Carefully avoid giving any help by look of approval or disapproval, by glancing at the part of the body indicated, or by supplementary questions.
Scoring. The test is passed if all three questions are answered correctly, or if, in case of one error, the three additional questions are all answered correctly. The standard, therefore, is three out of three, or five out of six.
The chief danger of variation among different examiners in scoring comes from double responses. For example, the child may point first to one ear and then to the other. In all cases of double response, the rule is to count the second response and disregard the first. This holds whether the first response was wrong and the second right, or vice versa.
Remarks. It is interesting to follow the child’s acquisitions of language distinctions relating to spacial orientation. Other distinctions of this type are those between up and down, above and below, near and far, before and behind, etc. As Bobertag has pointed out, the child first masters such distinctions as up and down, above and below, before and behind, etc., and arrives at a knowledge of right and left rather tardily.
