The Psychology of Learning from Machines: Anthropomorphic AI and the Paradox of Automation in Education

As AI tutors enter classrooms at unprecedented speed, their deployment increasingly outpaces our grasp of the psychological and social consequences of such technology. Yet decades of research in automation psychology, human factors, and human-computer interaction provide crucial insights that remain underutilized in educational AI design. This work synthesizes four research traditions -- automation psychology, human factors engineering, HCI, and philosophy of technology -- to establish a comprehensive framework for understanding how learners psychologically relate to anthropomorphic AI tutors. We identify three persistent challenges intensified by Generative AI's conversational fluency. First, learners exhibit dual trust calibration failures -- automation bias (uncritical acceptance) and algorithm aversion (excessive rejection after errors) -- with an expertise paradox where novices overrely while experts underrely. Second, while anthropomorphic design enhances engagement, it can distract from learning and foster harmful emotional attachment. Third, automation ironies persist: systems meant to aid cognition introduce designer errors, degrade skills through disuse, and create monitoring burdens humans perform poorly. We ground this theoretical synthesis through comparative analysis of over 104,984 YouTube comments across AI-generated philosophical debates and human-created engineering tutorials, revealing domain-dependent trust patterns and strong anthropomorphic projection despite minimal cues. For engineering education, our synthesis mandates differentiated approaches: AI tutoring for technical foundations where automation bias is manageable through proper scaffolding, but human facilitation for design, ethics, and professional judgment where tacit knowledge transmission proves irreplaceable.

Novel highest-Tc superconductivity in two-dimensional Nb2C MXene

Currently, superconductivity in two-dimensional (2D) materials is a hot topic of research owing to their potential technological applications. Here, we report observation of superconductivity in a 2D Nb2C MXene with transition temperature of 12.5 K, which is the highest transition temperature in MXene attained till now. We systematically optimized the chemical etching process to synthesize the Nb2C MXene from its Nb2AlC MAX phase. The X-ray diffraction (XRD) shows a clear (002) peak indicating the successful formation of MXene as well as a significant increase in the c-lattice parameter from 13.83{\AA} to 22.72{\AA} that indicates the delamination of Nb2C MXene sheets as revealed by morphological study using scanning electron microscope. The Meissner effect is detected using superconducting quantum interference device (SQUID: Quantum design). Lower and upper critical fields as a function of temperature follow the Ginzburg-Landau (GL) theory indicating the superconducting nature of the Nb2C MXene. Strong-electron phonon interaction and the large density-of-states at Fermi level may cause the emergence of superconductivity at such a higher transition temperature which has theoretically been predicted for Mo2C MXene. Our work is a significant advancement in the field of research and potential applications of 2D MXene.
