Respiratory hygiene practices by the public during the 2009 influenza pandemic: an observational study.

Aims: To describe the public use of respiratory hygiene behaviours during the 2009 influenza pandemic and to test the feasibility of an observational method.

Methods: Respiratory behaviour was systematically observed at three public settings during August 2009 in the capital city of New Zealand (Wellington). Data on each coughing or sneezing event were collected.

Darwinian psychology, old and new.

Many senior American and British psychologists between c1890 and c1925 were engaged in an attempt to settle on a unified definition of the term "instinct" as a psychological construct. Whilst this enterprise failed, some of its basic concepts underpin today's project of evolutionary psychology. This claim is substantiated by an analysis of the similarities between William McDougall's "Social Psychology" (1908), in which he articulated his theory of instincts, and John Tooby's and Leda Cosmides' "The Psychological Foundations of Culture" (1992).
