“…Cognitive training is directly targeted at functions such as working‐memory, executive control and attention (Irazoki et al, 2020 ; Lobbia et al, 2019 ; Salmi et al, 2018 ). Encouraging data on its effects on cognitive performance, self‐efficacy and everyday functioning have boosted its diffusion in healthy populations across the lifespan (Chaturvedi et al, 2022 ; Clark et al, 2017 ; Ng et al, 2020 ), as well as in psychiatric (Keshavan et al, 2014 ; Vinogradov et al, 2012 ) and neurological (Lasaponara et al, 2021 ; van Balkom et al, 2020 ) conditions, particularly when pharmacological support is limited or absent. A key criterion for assessing the outcome of any training is the generalization of acquired skills to non‐trained functions, that is, so‐called “transfer.” Despite encouraging evidence of transfer to non‐trained cognitive functions and long‐lasting effects (Lintern & Boot, 2021 ), the actual extent of cognitive training effects is debated (e.g., Sala et al, 2019 ).…”
