Working memory plasticity in old age: practice gain, transfer, and maintenance.
Adult age differences in cognitive plasticity have been studied less often in working memory than in episodic memory. The authors investigated the effects of extensive working memory practice onExpand

Aging cognition: from neuromodulation to representation
Basic cognitive functions, such as the abilities to activate, represent, maintain, focus and process information, decline with age. A paradigm shift towards cross-level conceptions is needed in orderExpand

Dual-tasking postural control: Aging and the effects of cognitive demand in conjunction with focus of attention
Postural control in everyday life is generally accompanied by posture-unrelated cognitive activity. Thus, mild forms of dual-tasking postural control are the norm rather than the exception. Based onExpand

Transformations in the Couplings Among Intellectual Abilities and Constituent Cognitive Processes Across the Life Span
Two-component theories of intellectual development over the life span postulate that fluid abilities develop earlier during child development and decline earlier during aging than crystallizedExpand

Neural underpinnings of within-person variability in cognitive functioning.
Increased intraindividual variability (IIV), reflecting within-person fluctuations in behavioral performance, is commonly observed in aging as well as in select disorders including traumatic brainExpand

Brains swinging in concert: cortical phase synchronization while playing guitar
BackgroundBrains interact with the world through actions that are implemented by sensory and motor processes. A substantial part of these interactions consists in synchronized goal-directed actionsExpand

The correlative triad among aging, dopamine, and cognition: Current status and future prospects
The brain neuronal systems defined by the neurotransmitter dopamine (DA) have since long a recognized role in the regulation of motor functions. More recently, converging evidence from patientExpand

Episodic memory across the lifespan: The contributions of associative and strategic components
The structural and functional brain circuitries supporting episodic memory undergo profound reorganization in childhood and old age. We propose a two-component framework that combines and integratesExpand

Human Aging Magnifies Genetic Effects on Executive Functioning and Working Memory
We demonstrate that common genetic polymorphisms contribute to the increasing heterogeneity of cognitive functioning in old age. We assess two common Val/Met polymorphisms, one affecting theExpand

Genetic variation in dopaminergic neuromodulation influences the ability to rapidly and flexibly adapt decisions
The ability to rapidly and flexibly adapt decisions to available rewards is crucial for survival in dynamic environments. Reward-based decisions are guided by reward expectations that are updatedExpand
