Narrative review: GenAI cognitive offloading can boost immediate performance but shows a performance-learning dissociation, and which functions are offloaded matters more than whether AI is used
This narrative review searched peer-reviewed GenAI studies published through September 05, 2026 alongside foundational cognitive-offloading research and found that evidence does not support a simple positive or negative effect of GenAI on human cognition: GenAI-supported offloading of functions such as memory retrieval, processing, and learning can reduce required cognitive capacity and support high performance across a variety of tasks, yet the same offloading can in some cases reduce the quality of subsequent encoding, and recent GenAI studies show a consistent performance-learning dissociation in which gains from support available at the time typically carry over to later unsupported performance only slightly, not at all, or even negatively.
