Abstract
As artificial intelligence and robots increase in popularity, human emotional attachment to technologies has become a salient research topic. However, many studies face the challenges of lacking a clear definition of emotional attachment that is overarching to cover emotional attachment to different entities and of differentiating these types of attachment phenomena. After reviewing the classic and contemporary research on human emotional attachment to people, pets, and possessions, we propose a novel, generalized definition and model of attachment across a person’s lifespan that describes the mechanism of human emotional attachment. Our literature review revealed two distinct but overlapping broad categories of research on human attachment: human–human attachments and human–nonhuman attachments. Our model integrates psychological principles and mechanisms from both classic infant–mother attachment theory and contemporary consumer behaviour research on emotional attachment to nonhuman objects. Emphasis is placed on the central role of the self-concept in all forms of human emotional attachments. We define human emotional attachment as a psychological phenomenon characterized by (a) perceiving the attributes of the attachment object as congruent with the self (supporting the self-concept and self-worth), (b) eliciting emotional reactions, and (c) evoking attachment behaviours. More specifically, the new model may lead to a series of new research on human emotional attachment to technologies and on its relationship to individuals’ self-concept development and well-being.

Douglas J. Gillan, a Distinguished Professor in the Department of Psychology at North Carolina State University (NC State) in Raleigh, NC, received a B.A. in Psychology from Macalester College (St. Paul, MN) in 1974 and a Ph.D. in Biopsychology from the University of Texas at Austin in 1978. He was an NSF Postdoctoral Fellow at Yale University and a Sloan Foundation Cognitive Science Fellow at University of Pennsylvania. He worked for 10 years in industry at the General Foods Research Center and at Lockheed Engineering and Sciences at NASA-JSC. He returned to academia as a visiting scholar at Rice University, then as a faculty member at the University of Idaho, New Mexico State University (NMSU), and NC State. He served as the Head of the Departments of Psychology at NMSU and NC State for five years and ten years, respectively. Gillan is a Fellow of the Human Factors and Ergonomics Society. He has served as an Associate Editor of Human Factors and is a member of the editorial board of The Journal of Usability Studies. His research interests focus broadly on the interaction between humans and technology. He has investigated issues in human-computer interaction and humanrobot interaction. Much of his research has centered around the cognitive and perceptual processes that underlie comprehension of graphical and numerical displays of information. In addition, he has published extensively on the relation between science and practice in human factors and on mental models. The National Science Foundation and the Army Research Laboratory have funded his research.
