Robustness of emotion extraction from 20th century English books

In this paper, we test the robustness of emotion extraction from English language books published in the 20th century. Our analysis is performed on a sample of the 8 million digitized books available in the Google Books Ngram corpus by applying three …

Emergence of Leadership in a Group of Autonomous Robots

For modern biology and ethology, the reason for the emergence of leaders-followers patterns in groups of living organisms, is the need of social coordination. In this paper we attempt to examine factors contributing to the emergence of leadership, …

Regulatory Traits in Cultural Evolution

We call “regulatory traits” those cultural traits that are transmitted through cultural interactions and, at the same time, change individual behaviors directly influencing the outcome of future cultural interactions. The cultural dynamics of some of …

Orienting learning by exploiting sociality: an evolutionary robotics simulations

One of the advantages of sociality resides in the opportunity of exploiting the behavior of other individuals of the same group as a reliable source of information. In this paper we present an evolutionary simulation in which a population of 10 …

Social Facilitation on the Development of Foraging Behaviors in a Population of Autonomous Robots

In this paper we propose an adaptive algorithm based on a combination of selective reproduction, individual learning, and social learning. Social learning consists of a simple facilitation process that regulates the strength of individual learning on …

The evolution of pain

We describe two simple simulations in which artificial organisms evolve an ability to respond to inputs from within their own body and these inputs themselves can evolve. In the first simulation the organisms develop an ability to respond to a pain …

Social Learning and Cultural Evolution in Embodied and Situated Agents

In this paper we investigate whether social learning or the combination of individual and social learning can provide an adaptive advantage for artificial embodied agents that have to develop behavioural abilities that are too difficult or too costly …

Adaptation and Social Facilitation in a Population of Autonomous Robots

In this paper we present an evolutionary simulation in which a population of 10 mobile robots has to develop a simple behavior consisting in the discrimination of two different foraging areas present in the environment. We show that, given a minimal …
