Comparison of Attachment Behaviors in Home and Laboratory

Abstract
The attachment behaviors of 40 infants were assessed in the home and laboratory by means of time-sampled observations. Of the four attachment behaviors analyzed three, looking at mother, vocalizing to mother, and being within reach of the mother, occurred significantly more frequently in the home than in the laboratory. When amount of maternal behavior directed toward the infant was used as a covariate, these differences were no longer significant. These results are discussed in connection with the issue of the representativeness of laboratory observations.
