  We appreciate the effort by Schwarzkopf to examine alternative explanations
for predictive anticipatory activity (PAA) or presentiment (for first response,
see: Schwarzkopf 2014a; for additional response, see: Schwarzkopf 2014b, for
original article, see: Mossbridge et al. 2014). These commentaries are a
laudable effort to promote collegial discussion of the controversial claim of
presentiment, whereby physiological measures preceding unpredictable emotional
events differ from physiological measures preceding calm or neutral events
(Mossbridge et al., 2012; Mossbridge et al., 2014). What is called truth at any
given time in science has achieved that status through a continuous process of
measurement and interpretation based on the current knowledge at hand. Here we
address six points in his original commentary (Schwarzkopf 2014a), though our
responses are informed by the points he made in his his supplementary
commentary (Schwarzkopf 2014b). We hope our responses will help Schwarzkopf and
others understand our interpretation of these data.
