This research investigates how reliance on AI systems affects human cognition and reasoning. Using concepts from cognitive offloading, the study compares AI-assisted and independent problem solving, measuring verification behavior, reasoning depth, and decision confidence. The work explores whether increasingly capable AI tools may unintentionally reduce critical thinking and human expertise.

This research shows that pauses in information streams alter decision-making. After a break, the brain increases effort, giving greater weight to subsequent information—a “peak-after-break” effect. A computational model explains this as a performance-effort tradeoff. Findings challenge traditional theories and suggest strategic pauses can shape attention, memory, and judgment.

This research investigates how sign language experience reshapes the brain’s visual system. MRI studies show expanded hand-processing regions and reorganised face areas in both deaf and hearing signers, even when learning occurs in adulthood. The findings highlight neural plasticity and reveal how visual language transforms perception and brain organisation.
