Study: Exoskeleton Assistance Alters Perception and Decision-Making
1 reports · 1 sources
An arXiv study used an elbow-assist exoskeleton suit to examine the physiological, perceptual, and cognitive consequences of force augmentation during lifting, finding that although assistance reduced muscle activity, behavioral outcomes did not simply correspond to this biomechanical change. The study authors, Maria Molina-Sanchez et al., report that assistance reduced participants' perceived weight, but this effect was strongly influenced by their initial experience; assistance also selectively weakened adaptation to changes in environmental conditions; differences in effort-based decisions were likewise shaped by initial experience, rather than simply following the reduction in muscle activity or perceived fatigue. The authors therefore conclude that the perceptual and cognitive consequences of force augmentation cannot be inferred from biomechanical benefits alone and must be assessed alongside physical performance.

- Study: Biomechanical metrics cannot predict perceptual and cognitive consequences of force augmentation
An arXiv study used an elbow-assist exosuit to examine the physiological, perceptual, and cognitive consequences of force augmentation during lifting, finding that although assistance reduced muscle activity, behavioral outcomes did not simply correspond to this biomechanical change. Assistance reduced perceived weight, but this effect was strongly shaped by participants' initial experience; assistance also selectively reduced adaptation to changes in environmental conditions, and differences in effort-based decisions were likewise shaped by initial experience rather than simply following the decline in muscle activity or perceived fatigue. The authors therefore argue that the perceptual and cognitive consequences of force augmentation cannot be inferred from biomechanical benefits alone and must be assessed alongside physical performance.
