Journal ArticleDOI
The variable nature of cognitive control: a dual mechanisms framework.
TL;DR: Recent research is summarized that demonstrates how the DMC framework provides a coherent explanation of three sources of cognitive control variation - intra-individual, inter-individual and between-groups - in terms of proactive versus reactive control biases.
Journal ArticleDOI
Neurocognitive Aging and the Compensation Hypothesis
TL;DR: The authors examine the hypothesis that age-related overactivation is compensatory and discuss the compensation-related utilization of neural circuits hypothesis (CRUNCH) and discuss questions about strategy differences, and consider the functions that may be served by overactive brain areas.
Journal ArticleDOI
The Cognitive Neuroscience of Working Memory
TL;DR: Information-based multivariate analyses of human functional MRI data typically find evidence for the temporary representation of stimuli in regions that also process this information in nonworking memory contexts.
Journal ArticleDOI
How do emotion and motivation direct executive control
TL;DR: The 'dual competition' framework proposes that emotion and motivation affect both perceptual and executive competition, and the anterior cingulate cortex is hypothesized to be engaged in attentional/effortful control mechanisms and to interact with several other brain structures in integrating affectively significant signals with control signals in prefrontal cortex.
Journal ArticleDOI
Working Memory as an Emergent Property of the Mind and Brain
TL;DR: Evidence from behavioral, neuropsychological, electrophysiological, and neuroimaging studies, from monkeys and humans, is considered, as is the question of how to interpret delay-period activity in the prefrontal cortex.

Chapter 11 Working memory
TL;DR: This chapter demonstrates the functional importance of dopamine to working memory function in several ways and demonstrates that a network of brain regions, including the prefrontal cortex, is critical for the active maintenance of internal representations.

Descartes' Error: Emotion, Reason, and the Human Brain
TL;DR: The authors argued that rational decisions are not the product of logic alone - they require the support of emotion and feeling, drawing on his experience with neurological patients affected with brain damage, Dr Damasio showed how absence of emotions and feelings can break down rationality.
Journal ArticleDOI
Orienting of attention
TL;DR: This paper explores one aspect of cognition through the use of a simple model task in which human subjects are asked to commit attention to a position in visual space other than fixation by orienting a covert mechanism that seems sufficiently time locked to external events that its trajectory can be traced across the visual field in terms of momentary changes in the efficiency of detecting stimuli.
Journal ArticleDOI
A Neural Substrate of Prediction and Reward
TL;DR: Findings in this work indicate that dopaminergic neurons in the primate whose fluctuating output apparently signals changes or errors in the predictions of future salient and rewarding events can be understood through quantitative theories of adaptive optimizing control.
Journal ArticleDOI
Controlled and automatic human information processing: II. Perceptual learning, automatic attending and a general theory.
TL;DR: Tested the 2-process theory of detection, search, and attention presented by the current authors (1977) in a series of experiments and demonstrated the qualitative difference between 2 modes of information processing: automatic detection and controlled search.
