No such assumption is made in human infant research,Indeed,it is implicitly stated that infants excluded are exactly likethose used except for the fact that at that particular time of testingthey were \"uncooperative。\"  \nWhether this assumption is correct requires confirmation,for it maybe possible that these excluded infants constitute a special class ofsubjects and the inclusion of their data would greatly alter the results.The present investigation was a first attempt to explore this samplingproblem by observing the data available from \"incomplete\"subjects andcomparing it to \"complete!subjects seen at the same time.  \nMethod  \nSubjects.
