Preverbal children with autism understand the intentions of others

There is a ‘theory of mind’ theory of autism. Meltzoff has recently developed a procedure that gives a nonverbal assessment of ‘theory of mind’. A group of children with autism and a matched control group of normally developing infants were given three of Meltzoff’s tasks and three conventional, gestural imitation tasks. The children with autism showed the expected deficits on gestural imitation, but were significantly better than the normally developing infants on the Meltzoff tasks. The implications of these results for a number of theoretical issues are discussed.     

Effects of dehydroepiandrosterone sulfate and progesterone on spatial learning and memory in young and aged mice

Young (2-4 months) and aged (14-16 months) male Swiss-Webster albino mice (n = 7 per group) were subcutaneously injected with 20 mg/kg/day dehydroepiandrosterone sulfate (DHEAS), progesterone (P), DHEAS + P, or vehicle control and trained over a 5-day period in a Morris water maze. The subjects were tested 48 hr after training for memory recall as measured by latencies to locate the hidden platform, and trunk blood was collected immediately thereafter. As expected, latency to platform decreased for all groups over the 6 testing days, with aged mice taking longer to reach platform than did young mice. However, results did not support the hypotheses that DHEAS-treated mice would exhibit shorter latencies and that P-treated mice would show longer latencies to platform in comparison with age-matched controls. These results raise doubts about the effectiveness of commercially available supplements claiming to promote enhanced memory in humans.     

Ethnic Identity in Jewish Families

Forty-eight Jewish families living in Central New York were interviewed about the development of their ethnic identity. Within each family, parents and children were asked about how they developed their ethnic identity to explore qualitatively how Jewish identity shapes and influences family dynamics. The semi-structured family interviews were coded using a constant comparison methodology. Seven qualitative categories emerged (gendered decisions, negotiating continuity, family of origin, survivors, active learning, traditions, and cultural religion). Jewish identity formation in families and the implications for clinical practice are explored.
