Cost-Benefit Analysis in Reasoning∗
When an individual thinks about a problem, his decision to reason further may involve a tradeoff between cognitive costs and a notion of value. But it is not obvious that this is always the case, and the value of reasoning is not well-defined. This paper analyzes the primitive properties of the reasoning process that must hold for the decision to stop thinking to be represented by a cost-benefi...
متن کاملIntergroup Variation of Social Relationships in Wild Vervet Monkeys: A Dynamic Network Approach
Social network analysis is a powerful tool that enables us to describe and quantify relationships between individuals. So far most of the studies rely on the analyses of various network snapshots, but do not capture changes over time. Here we use a stochastic actor-oriented model (SAOM) to test both the structure and the dynamics of relationships of three groups of wild vervet monkeys. We found...
متن کاملDemonstration of Sarcocystis-like Parasites Found in Peripheral Blood
This report described Sarcocystis-like merozoites in peripheral blood smear of a woman with mild fever, rigor and musculoskeletal pain. Extracellular organisms with a pale blue cytoplasm and one or two nuclei were seen in her blood smear stained with Giemsa. Sarcocystis-like can be considered as a possible cause of some idiopathic febrile diseases.
متن کاملSimilarity in Food Cleaning Techniques within Matrilines in Wild Vervet Monkeys
Social learning and the formation of traditions rely on the ability and willingness to copy one another. A central question is under which conditions individuals adapt behaviour to social influences. Here, we demonstrate that similarities in food processing techniques emerge on the level of matrilines (mother-offspring) but not on the group level in an experiment on six groups of wild vervet mo...
متن کاملSupply and demand determine the market value of food providers in wild vervet monkeys.
Animals neither negotiate verbally nor conclude binding contracts, but nevertheless regularly exchange goods and services without overt coercion and manage to arrive at agreements over exchange rates. Biological market theory predicts that such exchange rates fluctuate according to the law of supply and demand. Previous studies showed that primates pay more when commodities become scarcer: subo...
