Neurocognitive processing efficiency for discriminating human nonalarm rather than alarm scream calls

New paper published in Plos Biology by S Fruhholz and others. Scream calls are more diverse in their signaling and communicative nature in humans than previously assumed, and, in contrast to a commonly observed threat processing bias in perceptual discriminations and neural processes, we found that especially non-alarm screams, and positive screams in particular, seem to have higher efficiency in speeded discriminations and the implicit neural processing of various scream types in humans.
