Children and Nature: Psychological, Sociocultural and Evolutionary Investigations

For much of human evolution, the natural world was one of the most important contexts of childrens maturation. Indeed, the experience of nature was, and still may be, a critical component of human physical, emotional, intellectual, and even moral development. Yet scientific knowledge of the significance of nature during the different stages of childhood is sparse. This book provides scientific investigations and thought-provoking essays on children and nature. Children and Nature incorporates research from cognitive science, developmental psychology, ecology, education, environmental studies, evolutionary psychology, political science, primatology, psychiatry, and social psychology. The authors examine the evolutionary significance of nature during childhood; the formation of childrens conceptions, values, and sympathies toward the natural world; how contact with nature affects childrens physical and mental development; and the educational and political consequences of the weakened childhood experience of nature in modern society.

Hardware companions?: what online AIBO discussion forums reveal about the human-robotic relationship

In this study, we investigated peoples relationships with AIBO, a robotic pet, through 6,438 spontaneous postings in online AIBO discussion forums. Results showed that AIBO psychologically engaged this group of participants, particularly by drawing forth conceptions of technological essences (75%), life-like essences (49%), mental states (60%), and social rapport (59%). However, participants seldom attributed moral standing to AIBO (e.g., that AIBO deserves respect, has rights, or can be held morally accountable for action). Our discussion focuses on how robotic pets (now and in the future) may (a) challenge traditional boundaries (e.g. between who or what can possess feelings), (b) extend our conceptions of self, companionship, and community, and (c) begin to replace interactions with live pets. We also discuss a concern that people in general, and children in particular, may fall prey to accepting robotic pets without the moral responsibilities (and moral developmental outcomes) that real, reciprocal companionship and cooperation involves. This research contributes to a growing literature on the human-robotic relationship.

What is a Human? - Toward Psychological Benchmarks in the Field of Human-Robot Interaction

In this paper, we move toward offering psychological benchmarks by which to measure success in building increasingly human-like robots. By psychological benchmarks we mean categories of interaction that capture conceptually fundamental aspects of human life, specified abstractly enough so as to resist their identity as a mere psychological instrument, but capable of being translated into testable empirical propositions. Six possible benchmarks are considered: autonomy, imitation, intrinsic moral value, moral accountability, privacy, and reciprocity. Finally, we discuss how getting the right group of benchmarks in human-robot interaction will, in future years, help inform on the foundational question of what constitutes essential features of being human

Robovie, You'll Have to Go into the Closet Now: Children's Social and Moral Relationships With a Humanoid Robot

Children will increasingly come of age with personified robots and potentially form social and even moral relationships with them. What will such relationships look like? To address this question, 90 children (9-, 12-, and 15-year-olds) initially interacted with a humanoid robot, Robovie, in 15-min sessions. Each session ended when an experimenter interrupted Robovies turn at a game and, against Robovies stated objections, put Robovie into a closet. Each child was then engaged in a 50-min structural-developmental interview. Results showed that during the interaction sessions, all of the children engaged in physical and verbal social behaviors with Robovie. The interview data showed that the majority of children believed that Robovie had mental states (e.g., was intelligent and had feelings) and was a social being (e.g., could be a friend, offer comfort, and be trusted with secrets). In terms of Robovies moral standing, children believed that Robovie deserved fair treatment and should not be harmed psychologically but did not believe that Robovie was entitled to its own liberty (Robovie could be bought and sold) or civil rights (in terms of voting rights and deserving compensation for work performed). Developmentally, while more than half the 15-year-olds conceptualized Robovie as a mental, social, and partly moral other, they did so to a lesser degree than the 9- and 12-year-olds. Discussion focuses on how (a) childrens social and moral relationships with future personified robots may well be substantial and meaningful and (b) personified robots of the future may emerge as a unique ontological category.

The Human Relation With Nature and Technological Nature

Two world trends are powerfully reshaping human existence: the degradation, if not destruction, of large parts of the natural world, and unprecedented technological development. At the nexus of these two trends lies technological nature—technologies that in various ways mediate, augment, or simulate the natural world. Current examples of technological nature include videos and live webcams of nature, robot animals, and immersive virtual environments. Does it matter for the physical and psychological well-being of the human species that actual nature is being replaced with technological nature? As the basis for our provisional answer (it is “yes”), we draw on evolutionary and cross-cultural developmental accounts of the human relation with nature and some recent psychological research on the effects of technological nature. Finally, we discuss the issue—and area for future research—of “environmental generational amnesia.” The concern is that, by adapting gradually to the loss of actual nature and to the increase of technological nature, humans will lower the baseline across generations for what counts as a full measure of the human experience and of human flourishing.

Robotic animals might aid in the social development of children with autism

This study investigated whether a robotic dog might aid in the social development of children with autism. Eleven children diagnosed with autism (ages 5-8) interacted with the robotic dog AIBO and, during a different period within the same experimental session, a simple mechanical toy dog (Kasha), which had no ability to detect or respond to its physical or social environment. Results showed that, in comparison to Kasha, the children spoke more words to AIBO, and more often engaged in three types of behavior with AIBO typical of children without autism: verbal engagement, reciprocal interaction, and authentic interaction. In addition, we found suggestive evidence (with p values ranging from .07 to .09) that the children interacted more with AIBO, and, while in the AIBO session, engaged in fewer autistic behaviors. Discussion focuses on why robotic animals might benefit children with autism.

Design patterns for sociality in human-robot interaction

We propose that Christopher Alexanders idea of design patterns can benefit the emerging field of HRI. We first discuss four features of design patterns that appear particularly useful. For example, a pattern should be specified abstractly enough such that many different instantiations of the pattern can be uniquely realized in the solution to specific problems in context. Then, after describing our method for generating patterns, we offer and describe eight possible design patterns for sociality in human robot interaction: initial introduction, didactic communication, in motion together, personal interests and history, recovering from mistakes, reciprocal turn-taking in game context, physical intimacy, and claiming unfair treatment or wrongful harms. We also discuss the issue of validation of design patterns. If a design pattern program proves successful, it will provide HRI researchers with basic knowledge about human robot interaction, and save time through the reuse of patterns to achieve high levels of sociality.

Water, Air, Fire, and Earth A Developmental Study in Portugal of Environmental Moral Reasoning

This study contributes to our understanding of the origins and development of the human relationship with nature. The authors interviewed 120 participants (aged approximately 10 years, 5 months; 13 years, 6 months; 16 years, 7 months; and 19 years, 4 months) in Lisbon, Portugal, about environmental moral issues that involved water pollution, air pollution, forest fires, and logging. Results showed that participants conceived of polluting their localwaterway as a violation of a moral obligation. Participants’ justifications for these and other evaluations included both anthropocentric appeals (e.g., to personal interests, human welfare, and aesthetics) and biocentric appeals (e.g., that nature has intrinsic value or rights). Participants’ conceptions of living in harmony with nature showed a developmental trend. Finally, cross-cultural comparisons with studies conducted in the United States and the Brazilian Amazon support theproposition that therearesubstantial similarities in the environmental moral reasoning of young people across diverse cultures.

Do people hold a humanoid robot morally accountable for the harm it causes

Robots will increasingly take on roles in our social lives where they can cause humans harm. When robots do so, will people hold robots morally accountable? To investigate this question, 40 undergraduate students individually engaged in a 15-minute interaction with ATRs humanoid robot, Robovie. The interaction culminated in a situation where Robovie incorrectly assessed the participants performance in a game, and prevented the participant from winning a

20 prize. Each participant was then interviewed in a 50-minute session. Results showed that all of the participants engaged socially with Robovie, and many of them conceptualized Robovie as having mental/emotional and social attributes. Sixty-five percent of the participants attributed some level of moral accountability to Robovie. Statistically, participants held Robovie less accountable than they would a human, but more accountable than they would a vending machine. Results are discussed in terms of the New Ontological Category Hypothesis and robotic warfare.
