Using social robots to encourage honest behaviours

This thesis presents a series of studies to understand if robots can promote more honest behaviours from people, when they are tempted to behave dishonestly. In Study 1 we see that a robot just presenting gaze behaviour inhibits cheating, but a robot doing small talk, does not. In Study 2 we see that participants cheated to an equal extent when doing the task in their homes alone or with a video of a robot looking at them. In Study 3 we find that including situation awareness in a robot (showing awareness of the participant behaviour), decreased cheating across the game. In Study 4 we see that priming participants for their relational self-concept does not enhance the situation awareness effect on cheating. In study 5 and 6 we explore participants perceptions, and we see that people consider it wrong to be dishonest towards a robot. However, they would feel low levels of guilt and justify it by the robots’ lack of capabilities, presence, and a human tendency for dishonesty. When prompted to evaluate what other’s/or their own attitudes would be regarding dishonesty, manipulating the caring behaviour of a robot, it shows no effect and people in general think others would be dishonest and hold themselves in a more neutral stance. Interestingly, people that show more negative attitudes towards robots tend to report that others will act more dishonestly as well as themselves. These are important considerations for the development of robots, in the future, to work alongside with humans.Esta tese apresenta uma série de estudos para perceber se os robôs podem promover comportamentos honestos nas pessoas. No Estudo 1 observa-se que um robô que apenas olha para o utilizador, inibe batota, mas um robô que apresenta algum comportamento verbal não tem o mesmo efeito. No estudo 2, vemos que os participantes fazem batota tanto sozinhos, nas suas casas, como na presença de um vídeo de um robô que simplesmente olha. No Estudo 3 incluindo no robô a capacidade de perceber as jogadas dos participantes e reagir a elas, diminui a batota ao longo do jogo. No Estudo 4 a inclusão de um priming para o auto-conceito relacional não aumenta o efeito encontrado no Estudo 3. Finalmente, no Estudo 5 e 6 exploram-se as perceções das pessoas, e verifica-se que consideram errado ser-se desonesto com um robô, mas reportando baixos níveis de culpa. Justificam a desonestidade por: falta de capacidades no robô, falta de presença e a existência de uma tendência humana para a desonestidade. Quando avaliadas as atitudes que os outros teriam ou eles próprios em ser-se desonesto, manipulando o carácter afetivo do robô, não existem efeitos e as pessoas no geral reportam que os outros serão desonestos mantendo-se a si mesmas numa posição neutra. Curiosamente, os que demonstram atitudes mais negativas face a interagirem com robôs, reportam mais desonestidade. Estas são considerações importantes para o desenvolvimento de robôs para colaborarem com humanos no futuro

People's Attitudes Towards the Use of Robots in the Social Services: A Multilevel Analysis Using Eurobarometer Data

Robots have been employed in the industrial sectors for over half a century; however, their appearance in the domestic sphere is a modern phenomenon, occurring in just the last decade. These so-called social robots are carrying out a variety of tasks traditionally carried out by humans, and in contexts in which they must interact with human beings. These kinds of social robots are now being used in the welfare services, providing assistive services and companionship for the infirm or elderly, and even children. Thus, the use of social robots in everyday life has triggered an animated debate about the acceptance of these devices by their end users. In this paper, multilevel analysis is applied using data from the Eurobarometer survey (sample size 27,901, covering 28 countries) to investigate how socio-demographic characteristics and country-level indicators of technological and economic development (the rate of high-technology manufactured exports, the cellular phone subscriptions rate and GDP) influence how robots are accepted in the realm of the social services. The results show that only individual (socio-demographic) and technology acceptance model (TAM) factors influence attitudes towards social robots. The effects of the contextual variables considered were not statistically strong enough to explain the attitudes towards social robots for social services

The effects of caregiving robots on mortality salience with the elderly

As the world’s population of elderly persons rises (He, Goodkind, & Kowal, 2016), there is an increasing demand for people to care for the elderly. Caregiving robots are a potential solution to this problem. Research (i.e. MacDorman, 2005) suggests that uncanny, humanlike robots may elicit death anxiety, but it remains unclear whether non-humanlike caregiving robots also elicit death anxiety. This study expands on MacDorman’s study and investigates the effects of caregiving robots on death thought accessibility (DTA) and death anxiety in the institutionalized elderly. This research focuses on how caregiving robots affect the close relationship buffer against death anxiety, as well as looking at self-esteem and locus of control as potential covariates of DTA and death anxiety. A video of a non-humanlike caregiving robot as a mortality salience induction and a video of a human caregiver as a control video are used as stimuli. The results showed no significant differences in death anxiety and DTA between the human and robot caregivers. There were no interactions involving self-esteem and locus of control. Implications are discussed

Intelligent support technologies for older people : an analysis of characteristics and roles

For almost two decades there have been many developments in using intelligent technologies to support older people, with many different terms proposed to describe these technologies including assistive robots, embodied conversational agents and relational agents. Many technologies have been proposed in many different configurations and many assistance roles have been explored. Characteristics of these technologies include tangible or virtual; anthropomorphic, biomorphic, creature or object-like; level of visual realism; paralinguistic abilities; interactivity; adaptability; movement; and positioning. The assistive roles proposed include providing information, advice and reminders, helping with physical tasks, monitoring, providing companionship and emotional support. This paper provides an overview of the characteristics and roles of these technologies and attempts to clarify some of the terminology used. It aims to provide a guide for researchers from the wide range of disciplines working on such technologies for supporting older people

Humanization of robots: is it really such a good idea?

The aim of this review was to examine the pros and cons of humanizing social robots following a psychological perspective. As such, we had six goals. First, we defined what social robots are. Second, we clarified the meaning of humanizing social robots. Third, we presented the theoretical backgrounds for promoting humanization. Fourth, we conducted a review of empirical results of the positive effects and the negative effects of humanization on human–robot interaction (HRI). Fifth, we presented some of the political and ethical problems raised by the humanization of social robots. Lastly, we discussed the overall effects of the humanization of robots in HRI and suggested new avenues of research and development.info:eu-repo/semantics/publishedVersio

Attachment and Sex with Robots: An Assessment from Mental Health Perspective

Nowadays, when robot technology advances very quickly, the place and level of robot in human life lead to great debate. The perspective of mental health experts about living with robot, wanting to marry with robot, and sex with robot is very important. In this review, the literature about using robot in infant, child, elderly care and intimacy, attachment and sex with robots tried to investigate from perspective of mental health

A brief review of robotics technologies to support social interventions for older users

In the last few decades, various studies demonstrated numerous robotics applications that can tackle the problem of the ageing population by supporting older people to live longer and independently at home. This article reviews the scientific literature and highlights how social robots can help the daily life of older people and be useful also as assessment tools for mild physical and mental conditions. It will underline the aspects of usability and acceptability of robotic solutions for older persons. Indeed, the design should maximise these to improve the users' attitude towards the actual use of the robots. The article discusses the advantages and concerns about the use of robotics technology in the social context with a vulnerable population. In this field, success is to assist social workers, not to replace them. We conclude recommending that care benefits should be balanced against ethical costs
