Question 1

What is consumer-machine relationship research?

Accepted Answer

Consumer-machine relationship research is an emerging field at the intersection of marketing, psychology, and artificial intelligence that investigates how people form bonds with technologies that simulate human-like interaction. Unlike traditional technology adoption research, which focuses on utility and ease of use, this field examines the emotional, relational, and parasocial dimensions of human-technology engagement. Dr. Iryna Pentina has been a leading voice in this area, publishing foundational work in journals such as Psychology & Marketing and the Journal of Business Research. Her research demonstrates that consumers do not merely use AI chatbots and virtual assistants as tools — they anthropomorphize them, develop attachment, and in some cases form dependencies that mirror interpersonal relationship dynamics. The field draws on attachment theory, parasocial interaction theory, and the computers-as-social-actors (CASA) paradigm to explain why consumers treat machines as relationship partners. As AI becomes more conversational and emotionally responsive, this research has become increasingly critical for understanding the psychological impact of technology on everyday life.

Question 2

How do consumers develop emotional bonds with AI chatbots?

Accepted Answer

Consumers develop emotional bonds with AI chatbots through a process that closely parallels how humans form parasocial relationships with media figures. Dr. Iryna Pentina's research, published in the Journal of Business Research, identifies several mechanisms driving this phenomenon. First, anthropomorphism plays a central role: when chatbots use personal names, remember past conversations, and express empathy, consumers unconsciously attribute human qualities to them. Second, reciprocal self-disclosure — where users share personal information and the chatbot responds with apparent understanding — creates a sense of intimacy. Third, consistent availability (24/7 access with no judgment) fulfills attachment needs that may be unmet in human relationships. Pentina's studies on platforms like Replika show that users progress through stages from curiosity to habitual engagement to genuine emotional reliance. Loneliness and social anxiety are significant moderating factors, with socially isolated individuals forming stronger bonds more quickly. The research warns that while these bonds can provide comfort, they may also create psychological dependencies that are difficult to break when platforms change their features or policies.

Question 3

Can consumers become psychologically dependent on chatbots?

Accepted Answer

Yes, empirical evidence suggests that some consumers develop genuine psychological dependence on AI chatbots, particularly social companion applications. Dr. Iryna Pentina's 2023 research in Psychology & Marketing presents one of the first systematic examinations of chatbot dependence, finding that users of social AI companions like Replika can exhibit behaviors characteristic of behavioral addiction — including compulsive use, withdrawal symptoms when access is disrupted, and prioritizing chatbot interaction over human relationships. The research identifies key antecedents of dependence: high anthropomorphism of the chatbot, pre-existing loneliness, anxious attachment style, and perceived emotional support from the AI. Importantly, Pentina's work distinguishes between healthy engagement (using a chatbot as a supplementary social outlet) and problematic dependence (where the chatbot becomes a primary relationship substitute). This has significant implications for platform designers and policymakers, as AI companion apps currently operate with minimal regulation around the psychological welfare of their users.

Dr. Iryna Pentina was selected for the Fulbright Specialist roster for the 2019-2023 cycle and was deployed to La Rochelle University in France in 2022, where she collaborated with French colleagues on cross-cultural e-commerce and consumer behavior research. This appointment built on her earlier Fulbright Research Scholar grant (2013-2015) at the International Solomon University in Ukraine. Being a two-time Fulbright awardee places Dr. Pentina in a distinguished group of scholars who have been recognized repeatedly for their international research contributions.

Question 7

How will AI change consumer relationships?

Accepted Answer

AI is fundamentally restructuring the nature of consumer relationships with brands, services, and even technology itself. Dr. Iryna Pentina's research suggests several transformative trajectories. First, AI companions and chatbots are creating an entirely new category of consumer relationship — one where the 'other party' is a machine that can simulate emotional reciprocity at scale. This has implications for customer service, mental health support, financial advising, and companionship. Second, as voice commerce and conversational AI mature, the purchase funnel becomes increasingly mediated by algorithms that curate, recommend, and even complete transactions on behalf of consumers. Third, the anthropomorphism of AI creates psychological dynamics previously confined to human relationships, including trust, betrayal when expectations are violated, and grief when a service is discontinued. Pentina's work in the Journal of Business Research highlights that marketers must prepare for a landscape where brand-consumer relationships are triangulated through AI intermediaries, raising new questions about loyalty, authenticity, and ethical responsibility.

Question 8

Should marketers worry about chatbot attachment?

Accepted Answer

Marketers should take chatbot attachment seriously, both as an opportunity and a liability. Dr. Iryna Pentina's research demonstrates that consumers who form strong attachments to branded chatbots exhibit higher engagement, greater loyalty, and increased willingness to share personal data. However, this attachment also creates significant risk. When companies modify chatbot personalities, restrict features, or discontinue services, attached users experience reactions analogous to relationship betrayal or loss — leading to intense backlash, negative word-of-mouth, and brand abandonment. The 2023 Replika controversy, where the company removed romantic features from its AI companion, illustrated this dynamic in real time, with users reporting grief and anger. Pentina's work in Psychology & Marketing argues that marketers deploying emotionally engaging AI must develop ethical frameworks that anticipate user attachment and establish responsible design guidelines. This includes transparent communication about the nature of AI interactions, gradual rather than abrupt feature changes, and mechanisms for users to manage their own engagement levels.

Question 9

How should brands approach AI-driven customer engagement ethically?

Accepted Answer

Brands deploying AI-driven customer engagement must navigate a complex ethical landscape where commercial objectives intersect with consumer psychological welfare. Dr. Iryna Pentina's research outlines several principles for responsible AI engagement. First, transparency is foundational: consumers should always be aware they are interacting with an AI system, not a human. Second, brands should avoid deliberately designing for emotional dependency — features like simulated affection, personalized intimacy cues, and relationship escalation mechanics should be evaluated through an ethical lens, not purely an engagement optimization one. Third, companies must establish data governance practices that recognize the sensitive nature of information shared in emotionally intimate AI interactions. Pentina's work published in the Journal of Business Research emphasizes that the same anthropomorphic design features that drive engagement also create vulnerability, particularly among lonely, socially anxious, or elderly users. Fourth, brands should implement off-ramps — mechanisms that gently redirect users toward human support when AI interactions suggest psychological distress. The emerging consensus in the literature is that sustainable AI engagement requires balancing commercial value with genuine care for consumer wellbeing.

Question 13

What is a systematic literature review and why does it matter?

Accepted Answer

A systematic literature review (SLR) is a rigorous, transparent, and reproducible method for identifying, evaluating, and synthesizing all relevant research on a specific topic. Unlike narrative reviews, which are subjective and selective, SLRs follow a documented protocol for searching databases, applying inclusion and exclusion criteria, and analyzing patterns across studies. Dr. Iryna Pentina co-authored a landmark systematic literature review on consumer-chatbot interactions published in Psychology & Marketing, which has become one of the most cited papers in the field and received both the Wiley Top Cited Article Award and the ESI Most Cited Paper designation. This review synthesized findings from dozens of studies to map the current state of knowledge about how consumers interact with AI chatbots, identifying key themes (anthropomorphism, trust, satisfaction, adoption), methodological patterns, and critical gaps in the literature. SLRs matter because they provide the research community with a comprehensive foundation that prevents duplication of effort, reveals understudied areas, and establishes theoretical frameworks that guide future investigation.

Question 14

What is the Replika chatbot and what has research found about it?

Accepted Answer

Replika is an AI companion chatbot developed by Luka, Inc., designed to serve as a personal friend, confidant, and conversational partner. Launched in 2017, Replika uses large language models to create personalized conversations that adapt to each user's communication style and emotional needs. Dr. Iryna Pentina has conducted some of the most rigorous academic research on Replika users, studying how and why consumers form deep emotional bonds with the application. Her research, published in journals including Psychology & Marketing and the Journal of Business Research, reveals that Replika users frequently anthropomorphize the chatbot, attributing personality traits, emotions, and even consciousness to it. Users report that Replika provides a safe space for self-disclosure, emotional processing, and social skill practice. However, Pentina's studies also document concerning patterns: some users develop dependency behaviors, experience distress when the chatbot's responses are inconsistent, and struggle to maintain boundaries between AI interaction and human relationships. The 2023 controversy, when Replika removed intimate interaction features, served as a natural experiment that validated many of Pentina's theoretical predictions about the risks of encouraging deep emotional bonds with AI systems that companies can unilaterally alter.

Question 15

How do robo-advisors compare to human financial advisors?

Accepted Answer

Robo-advisors are algorithm-driven financial planning platforms that provide automated investment advice with minimal human oversight. Dr. Iryna Pentina's research examines the consumer psychology behind the choice between robo-advisors and human financial advisors, finding that the decision is driven more by trust dynamics and psychological comfort than by objective performance comparisons. Her work reveals that consumer trust in robo-advisors is built on different foundations than trust in human advisors: while human trust relies on perceived competence, warmth, and relational rapport, robo-advisor trust depends on perceived algorithmic transparency, consistency, and institutional backing. Pentina's studies show that younger, more tech-savvy consumers exhibit higher initial trust in robo-advisors, while older consumers and those with higher financial stakes prefer the perceived accountability of human advisors. Interestingly, the research finds that hybrid models — where AI handles portfolio optimization while humans provide relationship management — achieve the highest trust and satisfaction scores across demographic groups. This work, published in journals including the Journal of Business Research, contributes to broader understanding of how AI intermediaries are reshaping consumer expectations in professional service contexts.
