This symposium was part of a series started last year.At the beginning,we discussed what was essentials for a development of early infants.It was found that organizations 1) of material environment including rythmical organization in daily life, 2) relations in infants, 3) leading,were to be considered as essential elements in such a development.<BR>The second session discussed relations in infants concerning two of the above and its method of approach. Three reporters shared the ideas on the subject but using different methods. Shimizu reported on infant relations at home and at the nursery,especially infants from 6 months old to 1.5 years old.On this age the part of adults is lead infant's act meaning.In that level it was said that adults have the same part at home and at the nursery.But the phenomena of adult-infant relations showed differences with each plase.<BR>The Second reporters were from a Hospital for infant rearing.Suzuki talked on the subject of infant rearing in relations with infants among themselves. Yonekawa reported the result of an experimental study of relations in a hospital for infants from the view point of “looking at” and “touching” adults and peers.(Differences between “adult→inf ant” and “infant?.adult”.were found).<BR>A third reporter,Miyake,referred to studies of peer interaction in Europe and America;the trend and a point in dispute of such studies were talked at length.-DISCUSSION-From the very beginning Takahashi gave four points for discussion on the subject.Its contents were discussed by other speakers and a summary follows.<BR>Nagano pointed out the importanse for nursery teacher to connect conscious infant peers looking for interactions in phenomena.<BR>Discussion was brought up on two of Takahashi's four points 1) About a methodological problem i, e.Relations between field and laboratory study,<BR>2) About relations between both interactions of “adults?infants” and of peers in early infancy.<BR>1) It was agreed that both studies correlated with each other.But both researchers were asked on what to think of a context or how to observe infant behavior.One of the answers was that the field situation was very changeable from meaningless to very significant.<BR>A consideration of relations between researchers and infants in field situation was needed.Also another method has to be found as to the data of a laboratory to a field situation.<BR>2) As for the second subject there was little discussion Nowadays it was agreed upon the need for both human relations of adult⇔infant and of peer interaction.So it is up to us to better clarify the origin of growth in both relations between continuity and discontinuity on a developmental process of human interactions.
