SPEAKING-VOCABULARY TEST
Character of the Test.
One of the best measures of the intellectual capacity of a community or of a race of people is the complexity of the language which they find it necessary to use in their life and social intercourse. The speaking vocabulary of a tribe or of an individual is therefore an unusually accurate index of mental capacity. The present test of speaking vocabulary is designed to be used as an individual test for measuring the vocabulary of English-speaking persons. With some alterations in the directions which are given below the test might be used as a group test, but the results from such a group test would be quite different and practically not comparable with the results to be obtained when the test is given according to directions.
The individual to be examined need not be able to read English but must be able to understand ordinary conversational words and sentences. The examiner pronounces very distinctly the word which appears on his list and asks the candidate to explain the meaning of the word. The list used by the examiner contains fifty words, which are roughly graded, from the most common and well-known words used in every-day life up to very unusual and little-known words that would be found very rarely in newspaper or magazine articles. Any definition is accepted which shows that the candidate really understands the nature and use of the thing mentioned.
This test is modelled directly upon the Vocabulary test included in the Stanford Revision of the Binet tests. It has been shown by careful scientific investigations that a test of this type is very reliable as a measure of general intellectual capacity. The excuse for having, at the end of the series, words which are little known and of no great practical value is that without such words it would be impossible to obtain a real measure of the vocabulary of writers, well-trained lawyers, and other specialists in the use of the English language. The good scientific test of intelligence always begins with elements which are so simple that the dullest mind will master them and progresses steadily to elements which are so complex and difficult that even the keenest minds have difficulty in reaching satisfactory solutions.
A test of this sort measuring general vocabulary will be very useful to employers in the selection of stenographers and other clerical workers. In the public schoolroom teachers will find it very helpful in the classification of new pupils coming to their room for the first time or in the comparison of pupils who have been observed for a long period. The disadvantage of the test is that it must be given to one individual at a time. Such procedure makes it possible, however, for the teacher or the psychologist to study the more or less intangible attitudes and reactions of the pupil which cannot be observed in group examinations. These peculiarities of the pupil are of tremendous value to the trained psychologist or to the psychiatrist in making a careful diagnosis of special mental defects.
Directions for Giving the Test.
This test should not be given in the presence of outsiders. The examiner should take the individual to as quiet a place as possible, should seat the candidate in a comfortable chair, and converse with him until he is thoroughly at ease and ready to answer any sort of question. The examiner may write on his list the response which is made by the candidate to each word in the vocabulary. The formula which should be used by the examiner should be as nearly as possible that of ordinary conversation, although care must be used to avoid suggesting by the form of the question any clue to the proper response. Beginning with the first word, after introducing the general idea by some such phrase as “Now, I am going to ask you the meanings of a list of words,” the examiner should say, “The first word is coat. What is a coat?”
If the candidate does not seem to understand, the question may be repeated or it may be presented as follows: “You know what a coat is, do you not? Well, what is a coat?”
