Artificial intelligence (AI) is ubiquitous in this era. As a result, human-AI interactions are becoming more frequent and complex, and this trend is expected to accelerate soon. Therefore, scientists have made remarkable efforts to better understand human-AI relationships in terms of trust and companionship. However, these man-machine interactions can possibly also be understood in terms of attachment-related functions and experiences, which have traditionally been used to explain human interpersonal bonds.
In an innovative work, which incorporates two pilot studies and one formal study, a group of researchers from Waseda University, Japan, including Research Associate Fan Yang and Professor Atsushi Oshio from the Faculty of Letters, Arts and Sciences, has utilized attachment theory to examine human-AI relationships. Their findings were recently published online in the journal Current Psychology on May 9, 2025.
Mr. Yang explains the motivation behind their research. “As researchers in attachment and social psychology, we have long been interested in how people form emotional bonds. In recent years, generative AI such as ChatGPT has become increasingly stronger and wiser, offering not only informational support but also a sense of security. These characteristics resemble what attachment theory describes as the basis for forming secure relationships. As people begin to interact with AI not just for problem-solving or learning, but also for emotional support and companionship, their emotional connection or security experience with AI demands attention. This research is our attempt to explore that possibility.”
Notably, the team developed a new self-report scale called the Experiences in Human-AI Relationships Scale, or EHARS, to measure attachment-related tendencies toward AI. They found that some individuals seek emotional support and guidance from AI, similar to how they interact with people. Nearly 75% of participants turned to AI for advice, while about 39% perceived AI as a constant, dependable presence.
This study differentiated two dimensions of human attachment to AI: anxiety and avoidance. An individual with high attachment anxiety toward AI needs emotional reassurance and harbors a fear of receiving inadequate responses from AI. In contrast, a high attachment avoidance toward AI is characterized by discomfort with closeness and a consequent preference for emotional distance from AI.
However, these findings do not mean that humans are currently forming genuine emotional attachments to AI. Rather, the study demonstrates that psychological frameworks used for human relationships may also apply to human-AI interactions. The present results can inform the ethical design of AI companions and mental health support tools. For instance, AI chatbots used in loneliness interventions or therapy apps could be tailored to different users’ emotional needs, providing more empathetic responses for users with high attachment anxiety or maintaining respectful distance for users with avoidant tendencies. The results also suggest a need for transparency in AI systems that simulate emotional relationships, such as romantic AI apps or caregiver robots, to prevent emotional overdependence or manipulation.
Furthermore, the proposed EHARS could be used by developers or psychologists to assess how people relate to AI emotionally and adjust AI interaction strategies accordingly.
“As AI becomes increasingly integrated into everyday life, people may begin to seek not only information but also emotional support from AI systems. Our research highlights the psychological dynamics behind these interactions and offers tools to assess emotional tendencies toward AI. Lastly, it promotes a better understanding of how humans connect with technology on a societal level, helping to guide policy and design practices that prioritize psychological well-being,” concludes Mr. Yang.

As artificial intelligence and smart devices continue to evolve, machine vision is taking an increasingly pivotal role as a key enabler of modern technologies. Unfortunately, despite much progress, machine vision systems still face a major problem: processing the enormous amounts of visual data generated every second requires substantial power, storage, and computational resources. This limitation makes it difficult to deploy visual recognition capabilities in edge devices—such as smartphones, drones, or autonomous vehicles.
Interestingly, the human visual system ...
DARIEN, IL – A new study to be presented at the SLEEP 2025 annual meeting found that adolescents who prefer to sleep and wake up later (“night owls”) reported greater impulsivity than those who prefer to sleep and wake up earlier (“morning larks”).
Results show that adolescents with self-reported evening preference, or “night owl” tendencies, reported greater negative urgency and lack of perseverance, which are two aspects of impulsivity. This means that they were more likely to act impulsively when experiencing negative emotions and quit difficult tasks. In contrast, ...
Scientists analysing an ultra-hot giant planet believe it was formed by absorbing lightweight gases like methane evaporating from tiny space pebbles, whilst being bombarded with large rocky objects.
Using the James Webb Space Telescope (JWST) to explore the atmosphere of WASP-121b, researchers successfully detected water (H₂O), carbon monoxide (CO), and silicon monoxide (SiO) in the side facing its star or ‘dayside’. They also found methane (CH₄) in the planet’s ‘nightside’ atmosphere.

In the Paris Agreement of 2015, the international community of countries agreed to limit global warming to well below 2 °C, and preferably to 1.5 °C, compared to pre-industrial levels. This refers to the increase in global surface air temperature, inspected at any time of interest as an average over 20 years. The latest IPCC report expected the 1.5 °C threshold to be reached between 2030 and 2035. Climate researcher Gottfried Kirchengast from the Wegener Center and Institute of Physics at the University of Graz now has to revise this estimate: “Our ...
Flooding in coastal communities is happening far more often than previously thought, according to a new study from North Carolina State University and the University of North Carolina at Chapel Hill. The study also found major flaws with the widely used approach of using marine water level data to capture instances of flooding.
“Government agencies and researchers use data from tide gauges to measure water levels in coastal areas, then use that data to estimate flood frequency in the region,” says Miyuki Hino, corresponding author of a paper on the study and assistant professor of city and regional planning at UNC. “Those estimates ...
Forests in the Peruvian Amazon aren’t growing back after gold mining — not just because the soil is damaged from toxic metals, but because the land has been depleted of its water. A common mining method known as suction mining reshapes the terrain in ways that drain moisture and trap heat, creating harsh conditions where even replanted seedlings can’t survive.
The findings, published in Communications Earth & Environment, revealed why reforestation efforts in the region have struggled. One of the study’s co-authors is Josh West, professor of Earth sciences and environmental studies at the USC Dornsife College of Letters, Arts and Sciences.

Observations with the James Webb Space Telescope (JWST) have provided new clues about how the exoplanet WASP-121b has formed and where it might have originated in the disc of gas and dust around its star. These insights stem from the detection of multiple key molecules: water vapour, carbon monoxide, silicon monoxide, and methane. With these detections, a team led by astronomers Thomas Evans-Soma and Cyril Gapp was able to compile an inventory of the carbon, oxygen, and silicon in the atmosphere of WASP-121b. The detection of methane in particular also suggests strong vertical winds on the cooler nightside, a process often ignored in current ...
