Humans identify negative (but not positive) arousal in silver fox vocalizations: Implications for the adaptive value of interspecific eavesdropping
eavesdropping emotional arousal emotional valence
2017/8/28
The ability to identify emotional arousal in heterospecific vocalizations may facilitate behaviors that increase survival opportunities. Crucially, this ability may orient inter-species interactions, ...
Humans recognize emotional arousal in vocalizations across all classes of terrestrial vertebrates: Evidence for acoustic universals
emotional arousal language evolution vocal communication
2017/8/28
Writing over a century ago, Darwin hypothesized that vocal expression of emotion dates back to our earliest terrestrial ancestors. If this hypothesis is true, we should expect to find cross-species ac...
Directed Communication between Nucleus Accumbens and Neocortex in Humans Is Differentially Supported by Synchronization in the Theta and Alpha Band
Nucleus Accumbens Neocortex
2015/12/18
Here, we report evidence for oscillatory bi-directional interactions between the nucleus
accumbens and the neocortex in humans. Six patients performed a demanding covert
visual attention task while ...
Testing a postulated case of intersexual selection in humans: The role of foot size in judgments of physical attractiveness and age
Sexual selection Sexual dimorphism Attractiveness Foot size
2015/4/20
The constituents of attractiveness differ across the sexes. Many relevant traits are dimorphic, suggesting that they are the product of intersexual selection. However, direction of causality is genera...
Recent game-theoretic simulation and analytical models have demonstrated that cooperative strategies mediated by indicators of cooperative potential, or “tags,” can invade, spread, and resist invasion...
A Voice-Commandable Robotic Forklift Working Alongside Humans in Minimally-Prepared Outdoor Environments
Alongside Humans Minimally-Prepared Outdoor Environments
2015/3/10
One long-standing challenge in robotics is the
realization of mobile autonomous robots able to operate safely
in existing human workplaces in a way that their presence is
accepted by the human occu...
