In this small‐scale preliminary study, we compared the correlation between assessments based on short videorecordings and infant observation. Five mother–infant dyads were assessed when the child was 1 year of age according to the Parent–Child Early Relational Assessment method (PCERA, 65 items) developed by Roseanne Clark (1985), using both observations covering 1 year and a 5‐min videorecording. The agreement between two video raters was sufficient (κ = 0.41–1.00 or proportion of agreement: 4/5–5/5) in 54 items. In 42 (78%) of these items, there was at least moderate agreement (κ = 0.41–1.00 or proportion of agreement 4/5–5/5), and in another 7 (13%) items fair (κ = 0.21–0.40 or proportion of agreement 3/5) agreement between the video and observation ratings, and both methods revealed the areas of strength and areas of concern of the dyads. Only a few items describing negative interactive style were assessed as identifying concern, but such items identified the dyad which was assessed to have the most constant problems. Most items describing positive interactive style and identifying the areas of concern in the interactive style according to both observation and video assessment were connected with the parental and dyadic engagement in the interaction. Five items with slight or poor (κ ≤ 0.20 or proportion of agreement 1/5–2/5) agreement between video rater and observer gave rise to questions about how the videorecording situation affected the behavior of the dyads, and about the limits of assessment methods and assessment of dyads with children of different ages and dyads from different cultures. ©2005 Michigan Association for Infant Mental Health. 相似文献

Female mice of strains selectively bred for aggressiveness or nonaggressiveness were injected with testosterone propionate (TF′) at the age of 2 days and as adults, or they were injected as adults only. Aggressive and sexual behavior was then tested with female, receptive female, and male partners before, during, and after the latter TP treatment. The females that had received both TP treatments displayed as much or as little aggression as males of the same strain, leading to the conclusion that aggressiveness genes are not linked with the male sex chromosome, even though they depend on it for their expression. The sexual behavior of the females of both strains that had received both TP treatments was altered to the male type. In the females of the aggressive strain even adult treatment alone was sufficient for this change. Aggressiveness and male sexual behavior would seem to be determined separately, although aggressiveness facilitates the display of male sexual behavior. 相似文献
