• Abstract: The rapid integration of digital technology into daily life has prompted sustained concern regarding its impact on human cognition. This integrative review synthesizes documented risks and negative associations across more than 500 empirical studies, including the established literature and the nascent body of work on generative artificial intelligence. Initial evidence suggests a potential evolution in the nature of cognitive risk: while research on earlier technologies predominantly describes disruptions to resource allocation, early findings on generative artificial intelligence point toward a hypothesized erosion of higher-order generative and metacognitive capabilities. We analyze these risks across basic cognitive processes, higher-order cognition, and integrated functional outcomes through four mechanisms: functional interference, neurochemical dysregulation, structural neuroplasticity, and psychosocial displacement. The synthesis further highlights that these associations are frequently moderated or attenuated by socioeconomic status and environmental factors, which often drive both technology use and cognitive outcomes. Finally, by reviewing principles of cognitive epidemiology, the paper examines how habitual digital offloading could theoretically deplete cognitive reserve, creating downstream risks for long-term health. The collective evidence suggests an efficiency-atrophy paradox, where digital tools optimize short-term task performance at the potential expense of the long-term cognitive effort required to maintain unassisted cognition. However, large gaps remain in the literature, particularly the need for longitudinal studies, specifically within adult and professional populations.

• Modeling cognitive load as a self-supervised brain rate with electroencephalography and deep learning [2.741266294612776]
  This research presents a novel self-supervised method for mental workload modelling from EEG data. The method is a convolutional recurrent neural network trainable with spatially preserving spectral topographic head-maps from EEG data to fit the brain rate variable. Findings point to the existence of quasi-stable blocks of learnt high-level representations of cognitive activation because they can be induced through convolution and seem not to be dependent on each other over time, intuitively matching the non-stationary nature of brain responses.

We notice that pure neural models tend towards an associative strategy under their chance-level performance, whereas neuro-symbolic combinations struggle in backward-blocking reasoning.
