However, a clear definition of the phenomenon is not yet available. This theoretical paper aims to clarify what intrinsic motivations are from a biological perspective. To this purpose, it first shows how intrinsic motivations can be defined contrasting them to extrinsic motivations from an evolutionary perspective: whereas extrinsic motivations guide learning of behaviours that directly increase fitness, intrinsic motivations drive the acquisition of knowledge and skills that contribute to produce behaviours that increase fitness only in a later stage. Given this difference, extrinsic motivations generate learning signals on the basis of events involving body homeostatic regulations, whereas intrinsic motivations generate learning signals based on events taking place within the brain itself. These ideas are supported by presenting some examples of biological mechanisms underlying the two types of motivations. The paper closes by linking the theory to the current major computational views on intrinsic motivations and by listing the main open issues of the field.","PeriodicalId":256921,"journal":{"name":"2011 IEEE International Conference on Development and Learning (ICDL)","volume":"257 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124241173","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the present paper we describe the application of two robotic platforms with different design parameters in interaction with children with autism and other cognitive impairments. IROMEC is a mobile robotic platform designed for children with different levels of disabilities to encourage them to be engaged in social interactions. KASPAR is a humanoid child-size robot designed for social interaction. KASPAR has been used extensively in studies with children with autism. The aim of this study is to examine how KASPAR and IROMEC can support social interaction and facilitate the cognitive and social development of children with special needs via play activities. Natural engagement in social play behaviour is often a problem in the development of children with disabilities. Due to the nature of their disabilities they are often excluded from such activities. As part of a long-term study we carried out different play scenarios based on imitation, turn taking and the cause and effect game according to the main educational and therapeutic objectives considered important for child development. In this paper we focus on the turn taking and the imitation game scenarios. A preliminary analysis of the data showed encouraging results. The level of the improvement of the children depended on the level and nature of their disabilities.","PeriodicalId":256921,"journal":{"name":"2011 IEEE International Conference on Development and Learning (ICDL)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130516010","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Empirical studies have furthermore identified numerous neuronal correlates of quantities necessary for such computations. But, in general it is too expensive for the brain to encode actions and their outcomes with respect to all available dimensions describing the state of the world. This suggests the existence of learning algorithms that are capable of taking advantage of the independencies present in the world and hence reducing the computational costs in terms of representations and learning. A possible solution is to use separate learners for task dimensions with independent dynamics and rewards. But the condition of independence is usually too restrictive. Here, we propose a hierarchical reinforcement learning solution for the more general case in which the dynamics are not independent but weakly coupled and show how to assign credit to the different modules, which solve the task jointly.","PeriodicalId":256921,"journal":{"name":"2011 IEEE International Conference on Development and Learning (ICDL)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121655038","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
