Thyme to touch: Infants possess strategies that protect them from dangers posed by plants

Plants have been central to human life as sources of food and raw materials for artifact construction over evolutionary time. But plants also have chemical and physical defenses (such as harmful toxins and thorns) that provide protection from herbivores. The presence of these defenses has shaped the behavioral strategies of non-human animals. Here we report evidence that human infants possess strategies that would serve to protect them from dangers posed by plants. Across two experiments, infants as young as eight months exhibit greater reluctance to manually explore plants compared to other entities. These results expand the growing literature showing that infants are sensitive to certain ancestrally recurrent dangers, and provide a basis for further exploration.     

Genetic Counseling Practices in Germany: A Comparison Between East German and West German Geneticists

As part of an international study of ethics and genetics, we present a comparison between survey responses of 43 East German and 212 West German geneticists to anonymous questionnaires. Both groups indicated that the experience of the Third Reich has impacted the genetics profession in Germany today. East German geneticists reported more directive counseling practices after prenatal diagnosis for 10 of 26 conditions than those from West Germany. When asked to give their personal opinions about pregnancy termination, East Germans were more accepting of abortion than their West German colleagues for 7 of 24 fetal indications. In addition, there were significant differences between the two sample groups for 8 questions on the perception of disability and society. Discussions with German geneticists suggest that, while both groups were affected by Germany's experience of Nazism, different abortion laws, political systems, and ideas about the doctor-patient relationship in former East and West Germany may account for discrepancies in reported genetic counseling practices and in attitudes toward abortion and disability.     

Stuttering following brain damage

This paper describes the neurological, language, and speech status of seven brain-damaged patients with symptoms of cortical stuttering. We compare data from our seven patients to data presented on other brain-damaged stutterers, review theories of cortical stuttering's etiology, advance alternative hypotheses about mechanisms underlying such dy sfluencies, and compare cortical stuttering to stuttering in childhood.
