The complex interaction between anxiety and cognition
Anxiety can be distracting, disruptive, and incapacitating. Despite problems with empirical replication of this phenomenon, one fruitful avenue of study has emerged from working memory (WM) experiments where a translational method of anxiety induction (risk of shock) has been shown … Continue reading
The impact of anxiety upon cognition
Anxiety disorders constitute a sizeable worldwide health burden with profound social and economic consequences. The symptoms are wide-ranging; from hyperarousal to difficulties with concentrating. This latter effect falls under the broad category of altered cognitive performance which is the focus … Continue reading
How Poverty Taxes the Brain
In a series of experiments run by researchers at Princeton, Harvard, and the University of Warwick, low-income people who were primed to think about financial problems performed poorly on a series of cognition tests, saddled with a mental load that … Continue reading
Cognitive stigmergy: A study of emergence in small-group social networks
This paper proposes a model and theory of leadership emergence whereby (1) small social groups are modeled as small-world networks and a betweeness metric is shown to be a property of networks with strong leadership, and (2) a theory of … Continue reading
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
Cognitive costs of decision-making strategies
Several theories of cognition distinguish between strategies that differ in the mental effort that their use requires. But how can the effort—or cognitive costs—associated with a strategy be conceptualized and measured? We propose an approach that decomposes the effort a … Continue reading

Does speaking a second language really improve cognition?
The idea that learning to speak two languages is good for your brain has come to be widely accepted as fact, particularly in popular media. Studies have shown that bilingual speakers of all ages outperform monolinguals on certain cognitive performance … 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
