Effects of presence of mother versus preschool teacher on the behaviour of infants in a strange situation

Seventeen infants (10–24 months of age) were observed twice in a strange situation, once accompanied by mother and once in the company of a familiar preschool teacher. On basis of video-tape recordings a total of 13 behaviour items relevant to infant attachment were scored. The results failed to demonstrate definite differential effects of mother vs. preschool teacher on the infants' behaviors in this situation. In particular, the infants were just as ready to separate themselves from their companions and explore into an adjoining room when attended by the preschool teachers as when accompanied by their mothers. Implications for Ainsworth's and Bowlby's theory of infant attachment are briefly discussed.
