A staggered rollout to 5,172 customer-support agents increased issues resolved per hour by 15% on average. Less experienced workers gained most, while the most experienced saw smaller gains and slight quality declines.
Across experiments with 1,401 participants, biased AI altered human perceptual, emotional, and social judgements and could amplify bias over time. Participants often underestimated the system influence.
This preregistered synthesis of 106 experiments and 370 effect sizes found that human-AI combinations underperformed the better standalone agent on average. Outcomes varied materially by task, with losses in decisions and gains in content creation.
A PRISMA-guided meta-analysis of 22 studies and 43 effects found a small overall negative relationship between smartphone presence or use and cognitive performance, with substantial differences by cognitive domain and region.
In a preregistered experiment with 453 professionals, ChatGPT access reduced task time by 40% and increased assessed output quality by 18%. Lower-skill participants benefited most on the short writing tasks studied.
A Bayesian framework models when human and machine classifiers can complement one another while accounting for differences in expressed confidence. The result is useful for hybrid design but is centered on classification tasks.
Mixed-method studies across three datasets found gains from AI assistance, but explanations did not improve complementary performance. Explanations increased acceptance of AI advice whether that advice was correct or not.
This multidisciplinary review argues that online environments can produce immediate and sustained changes in attention, memory, and social cognition, while effects vary by activity, population, and life stage.
Two controlled experiments found the best working-memory and fluid-intelligence performance when phones were in another room and the lowest when phones were visible. Later replication results are mixed.
This review defines cognitive offloading as using physical action or external tools to reduce internal processing demands. It links offloading choices to beliefs about personal ability and external-aid reliability.
Across nine experiments, online search increased participants estimates of their own explanatory knowledge, including on unrelated topics. The studies identify confusion between access to external information and internally held knowledge.
Four experiments found that expecting future access reduced memory for information itself but improved memory for where it could be found, supporting a transactive-memory account of Internet use.
Heavy media multitaskers were more susceptible to interference from irrelevant stimuli and memory representations and performed worse on task switching. The group-comparison design does not establish causality.
