Mimicking disliked others: Effects of a priori liking on the mimicry‐liking link

The sharing of bodily states elicits in mimicker and mimickee corresponding conceptualisations, which facilitates liking. There are many studies showing the relatedness of mimicry and liking. However, the mimicry‐liking link has not been investigated under conditions in which the mimickee is liked or disliked a priori. In two studies, we examined moderating effects of a priori liking on the mimicry‐liking link. Liking was measured via self‐report measures (Studies 1 and 2) and behavioural measures using a virtual environment technology (Study 2). Results showed that when participants intentionally mimicked a disliked person, liking for that person was not improved, whereas when participants mimicked a liked person, liking for that person increased. These effects were shown to be mediated by affiliation. These studies not only provided further evidence of a link between mimicry and liking, but also demonstrated that this relationship is moderated by a priori liking.

Specific extreme behaviors of postinstitutionalized Russian adoptees

Behavior problems reported by parents on the Child Behavior Checklist (Achenbach & Rescorla, 2001) were studied in 316 children adopted from social-emotionally depriving Russian institutions as a function of age at adoption (18-month cutoff), age at assessment (6-11 and 12-18 years), and gender. Children adopted after 18 months had higher problem scores predominately when assessed at 12-18 years. Although most children had no behavior problems, 59.0% of later adoptees assessed in adolescence had at least 1 subscale score and 48.7% had 2 or more subscale scores in the clinical/borderline range. A factor analysis of items that significantly related to age at adoption for older children revealed 1 broad factor, encompassing different antisocial behaviors, social difficulties, and withdrawal. These results may suggest a somewhat broader deficiency produced by orphanage experience beyond the first 18 months of life that underlies a range of behavioral problems displayed later.     

CBCL Behavior Problems of Post-Institutionalized International Adoptees

With the increase in international adoptions during the last decade, many researchers have investigated the developmental outcomes of these adoptees, including their extreme behaviors. Collectively, these results have not always appeared consistent across studies, perhaps because studies have used children reared in institutions or not, the institutional environments vary in severity, children spend different lengths of time in the institution and are assessed at different ages, and studies use different outcome measures. In an attempt to discern more order in the literature, this review focuses on 18 studies, each of which used the Child Behavior Checklist, and their outcomes are viewed with respect to these parameters. Results suggest that the major factor contributing to extreme behaviors is age at adoption, with those adopted after 6/18 months having more behavior problems, especially Internalizing, Externalizing, and Attention problems. Generally, samples of post-institutional children have more problems than samples of mixed or non-institutional internationally adopted children, and some problems are more likely to be manifest in adolescence, suggesting the effects of deficient early experiences are not simply the persistence of learned behavior but more general dispositions that become more noticeable or severe during adolescence. Findings are discussed in terms of early deficient social–emotional caregiver–child interactions that characterize most institutional environments as a possible major cause of later difficulties in post-institutionalized children.
