Primates often react to possible predators by using intimidation displays, although the occurrence of these displays is dependent on the risk of predation. Functional explanations for these kinds of displays range from sexual selection to predator deterrence. The ability to respond to different predators can be socially acquired, and social traditions could(More)
Cognition presents evolutionary research with one of its greatest challenges. Cognitive evolution has been explained at the proximate level by shifts in absolute and relative brain volume and at the ultimate level by differences in social and dietary complexity. However, no study has integrated the experimental and phylogenetic approach at the scale(More)
In this paper we report on the acquisition and content of a new database intended for developing audiovisual speech recognition systems. This database supports a speaker dependent continuous speech recognition task, based on a small vocabulary, and was captured in the European Portuguese language. Along with the collected multi-modal speech materials, the(More)
The preferential use of one limb (lateralization) has been observed in many species. This lateralization reflects functional asymmetries of the brain. Right-handedness and left-hemisphere dominance seem to be the norm in humans. However, suggestions that vertebrates, particularly non-human primates, show handedness are contentious. Tool use could be a(More)
The " Capuchin research community roundtable: working together towards a comparative biology of Cebus and Sapajus " was held at the International Primatological Society Congress in Cancún, Mexico, August 2012. Goals of the roundtable were to strengthen interactions among the capuchin research community, and to prioritize and coordinate research and training(More)
In this paper we studied the phonemic structure of the words' beginnings and endings in standard European Portuguese (hereafter EP). The generativist description of the Portuguese phonology [1] was used as framework basis and the phonetic and acoustic experiments performed by Delgado-Martins [2] served as a model to the phonetic background in EP. We also(More)
