Cognitive training can reduce the rate of cognitive aging

The neural mechanisms underlying the restorative effects of cognitive training on aging brains remain unclear. To address this issue, we examined the relationship between changes in spontaneous brain activity and cognitive performance that occur after cognitive training. Participants were older adults who … Continue reading

On the role of stigmergy in cognition

Cognition in animals is produced by the self-organized activity of mutually entrained body and brain. Given that stigmergy plays a major role in self-organization of societies, we identify stigmergic behavior in cognitive systems, as a common mechanism ranging from brain … Continue reading

Motivation, Emotion, and Cognition: Integrative Perspectives on Intellectual Functioning and Development

The central argument of this book is that cognition is not the whole story in understanding intellectual functioning and development. To account for inter-individual, intra-individual, and developmental variability in actual intellectual performance, it is necessary to treat cognition, emotion, and … Continue reading
