Juvenile offenders' Miranda rights comprehension and self-reported likelihood of offering false confessions

This study examined whether age, IQ, and history of special education predicted Miranda rights comprehension and the self-reported tendency to falsely confess to a crime among 55 delinquent boys. The Miranda Rights Comprehension Instruments-II, a revised version of Grisso's Instruments for Assessing Understanding and Appreciation of Miranda Rights, were developed for this study and are described in detail in this article. Results revealed that age, IQ, and special education were related to comprehension of Miranda rights. When Miranda comprehension, age, and IQ were simultaneously tested as predictor variables of the self-reported likelihood of false confessions, only age served as an independent predictor. Research and policy implications of this study are presented, and recommendations for use of the original and revised instruments are reviewed.     

Hostile/Helpless maternal representations in pregnancy and later child removal: A pilot study

This article presents the results of a small pilot study examining links between Hostile/Helpless (HH) representations of caregiving in pregnancy and later child removal by child protective services. The sample was drawn from a replication study of the Minding the Baby^® attachment‐based home‐visiting intervention conducted in the United Kingdom, serving young first‐time mothers in under resourced communities. The HH classification system (Lyons‐Ruth et al.) was adapted for use with the Pregnancy Interview (PI) (Slade); 26 PIs were assessed (coders blinded) in a sample that included 13 mothers whose infants were removed from custody due to anticipated or documented maltreatment within 2 years of childbirth, and 13 mothers who did not have their infants removed. Mothers whose infants were removed from their custody had significantly higher HH scores than mothers of infants who were not removed from their care (F(1, 24) = 14.500, p < .001), and the relation between overall HH classification and infant removal status was also significant (χ²(1, N = 26) = 12.462, p < .001). Results suggest that prenatal maternal caregiving representations may predict postnatal relationship disruptions, and indicate the need for larger studies further testing this prenatal approach to maltreatment risk assessment in at‐risk populations.     

Effect of conspecific sex on aggression during pregnancy and lactation in golden hamsters

The effect of conspecific sex on maternal aggression in hamsters was determined by comparing the frequency of aggressive responses by dams continuously housed with either a virgin male or female cagemate during pregnancy and lactation. Dams easily established aggressive dominance over male cagemates soon after pairing, and their aggression was low thereafter for the duration of pregnancy and lactation. The aggression of dams with females, on the other hand, tended to fluctuate with highs during mid pregnancy and mid lactation and lows around birth. When dam aggression was low around birth, female cagemates frequently became aggressively dominant, and several dams lost their litters. The higher aggression of dams toward females than males is probably a reflection of greater intrasexual competition for environmental resources that includes pups.
