Topology and graph theory applied to cortical anatomy may help explain working memory capacity for three or four simultaneous items.

Cognitive experimentation suggests that at any single instant only three or four items ("chunks") are simultaneously prominent as a working memory (WM) trace, if we disregard the rehearsal component of WM. The reason for small WM capacity may concern ...

Independent component model for cognitive functions of multiple subjects using [15O]H2O PET images.

An independent component model of multiple subjects positron emission tomography (PET) images is proposed to explore the overall functional components involved in a task and to explain subject specific variations of metabolic activities under altered ...

Tracking cognitive processes with functional MRI mental chronometry.

Functional magnetic resonance imaging (fMRI) is used widely to determine the spatial layout of brain activation associated with specific cognitive tasks at a spatial scale of millimeters. Recent methodological improvements have made it possible to ...

Reality monitoring and metacognitive beliefs related to cognitive confidence in obsessive-compulsive disorder.

The present study investigated general reality monitoring ability, and selective reality monitoring ability for anxiety relevant actions in a group of individuals with obsessive-compulsive disorder (OCD) and a group of non-anxious controls. In addition, ...

The locus coeruleus-noradrenergic system: modulation of behavioral state and state-dependent cognitive processes.

Through a widespread efferent projection system, the locus coeruleus-noradrenergic system supplies norepinephrine throughout the central nervous system. Initial studies provided critical insight into the basic organization and properties of this system. ...

Attributional style predicts causes of negative life events on the Attributional Style Questionnaire.

The causes cited by 218 participants for the hypothetical positive and negative life events on the Attributional Style Questionnaire (ASQ) and the dimensional ratings of the causes were examined to determine the match between the dimensional and ...

Cognitive flexibility and adaptability to environmental changes in dynamic complex problem-solving tasks.

People who show good performance in dynamic complex problem-solving tasks can also make errors. Theories of human error fail to fully explain when and why good performers err. Some theories would predict that these errors are to some extent the ...

Mathematical phenomenology of neural stimulation by periodic fields.

Neuron synchronization has been hypothesized as the basic mechanism leading neurological phenomena like low electroencephalographic rhythm dimension or high coherence. Cognitive processes, such as associative memory, can also be explained in terms of ...

Normative data from the CANTAB. I: development of executive function over the lifespan.

The study of executive function within a developmental framework has proven integral to the advancement of knowledge concerning the acquisition and decline of higher skill processes. Still in its early stages, there exists a discontinuity in the ...

The effectiveness of early childhood development programs. A systematic review.

Early childhood development is influenced by characteristics of the child, the family, and the broader social environment. Physical health, cognition, language, and social and emotional development underpin school readiness. Publicly funded, ...
