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. 相似文献

This study addresses three questions. (1) Does the meaning of the neutral anchor shift when its position is moved away from the middle of the series? The location of (psychological) zero in rating scales is crucial if they are to be used as multipliers (e.g., as weights or in functional equations). (2) Does moving the neutral anchor from a central position increase sensitivity (variance) of ratings? Such displacement has been used frequently without investigation of its effects. (3) Are any of the above effects general across types of anchors? Displacement had significant effects (N= 210) on meaning of the neutral anchor and on sensitivity. Stability of meaning of anchors, however, was greater when anchors were words rather than faces. Therefore verbal anchors should be used, with the neutral anchor located centrally, to establish zero; but displaced to increase sensitivity at one end of the scale. 相似文献
