Informavores: Active information foraging and human cognition
Unlike a passive sponge floating in a sea of information, humans are active information foragers – informavores – who gather and consume new knowledge. From controlling the movement of our eyes to determining which sources of news to consult, judging the quality of alternative sources of information is a critical part of our behavior. The goal of this symposium is to bring together researchers ...
متن کاملSex differences in spatial cognition in an invertebrate: the cuttlefish.
Evidence of sex differences in spatial cognition have been reported in a wide range of vertebrate species. Several evolutionary hypotheses have been proposed to explain these differences. The one best supported is the range size hypothesis that links spatial ability to range size. Our study aimed to determine whether male cuttlefish (Sepia officinalis; cephalopod mollusc) range over a larger ar...
متن کاملForaging Cognition: Reviving the Ecological Intelligence Hypothesis.
What are the origins of intelligent behavior? The demands associated with living in complex social groups have been the favored explanation for the evolution of primate cognition in general and human cognition in particular. However, recent comparative research indicates that ecological variation can also shape cognitive abilities. I synthesize the emerging evidence that 'foraging cognition' - ...
متن کاملNumber sense and state-dependent valuation in cuttlefish.
Identifying the amount of prey available is an important part of an animal's foraging behaviour. The risk-sensitive foraging theory predicts that an organism's foraging decisions with regard to food rewards depending upon its satiation level. However, the precise interaction between optimal risk-tolerance and satiation level remains unclear. In this study, we examined, firstly, whether cuttlefi...
متن کاملAnimal Foraging and the Evolution of Goal-Directed Cognition
Foraging- and feeding-related behaviors across eumetazoans share similar molecular mechanisms, suggesting the early evolution of an optimal foraging behavior called area-restricted search (ARS), involving mechanisms of dopamine and glutamate in the modulation of behavioral focus. Similar mechanisms in the vertebrate basal ganglia control motor behavior and cognition and reveal an evolutionary p...
