The Strange Situation procedure was developed by Ainsworth two decades agoas a means of assessing the security of infant-parent attachment. Users of the procedureclaim that it provides a way of determining whether the infant has developed species-appropriate adaptive behavior as a result of rearing in an evolutionary appropriate context, characterized by a sensitively responsive parent. Only when the parent behaves in the sensitive, species-appropriate fashion is the baby said to behave in the adaptive or secure fashion. Furthermore, when infants are (...) observed repeatedly in the Strange Situation,the pattern of behavior is said to be highly similar, and this pattern is said to predict the infants' future behavior in a diverse array of contexts. After an exhaustive review of the literature, it is shown that these popular claims are empirically unsupported in their strong form, and that the interpretations in terms of biological adaptationare misguided. There is little reliable evidence about the specific dimensions of parental behavior that affect Strange Situation behavior, although there does appear to be some relationship between these constructs. Temporal stability in security of attachment ishigh only when there is stability in family and caretaking circumstances. Likewise, patterns of Strange Situation behavior only have substantial predictive validity in similarly stable families. Implications for future research and theorizing — particularly as they relate to the use of evolutionary biology in psychological theory — are discussed. (shrink)

Institutional review boards are almost universally considered to be overworked and understaffed. They also require substantial commitments of time and resources from their members. Although some surveys report average IRB memberships of 15 people or more, federal regulations require only five. We present data on IRB meetings at eight of the top 25 academic medical centers in the United States funded by the National Institutes of Health. These data indicate substantial contributions from primary reviewers and chairs during protocol discussions but (...) little from other members, which implies that it may be possible for smaller IRBs to accomplish the same tasks with no reduction in the quality of review.
