Cognitive component analysis (COCA) is defined as unsupervised grouping of data leading to a group structure wellaligned with that resulting from human cognitive activity. We focus here on speech at different time scales looking for possible hidden ‘cognitive structure’. Statistical regularities have earlier been revealed at multiple time scales corresponding to: phoneme, gender, height and spe...

Traumatic brain injury (TBI) is the most common cause of brain damage, resulting in long-term disability. The "reserve" construct has been proposed to account for the reported mismatch between brain damage and its clinical expression. Although numerous studies have used various measures thought to reflect this construct, few studies have examined its underlying structure in clinical populations...

According to cognitive models of reading, words are processed by interacting orthographic (spelling), phonological (sound), and semantic (meaning) information. Despite extensive study of the neural basis of reading in healthy participants, little group data exist on patients with reading deficits from focal brain damage pointing to critical neural systems for reading. Here, we report on one suc...

This article examines the role of cognitive, metacognitive, and motivational skills in problem solving. Cognitive skills include instructional objectives, components in a learning hierarchy, and components in information processing. Metacognitive skills include strategies for reading comprehension, writing, and mathematics. Motivational skills include motivation based on interest, self-efficacy...

OBJECTIVE—Diabetic and prediabtic states, including insulin resistance, fasting hyperglycemia, and hyperinsulinemia, are associated with metabolic dysregulation. These components have been individually linked to increased risks of cognitive decline and Alzheimer’s disease. We aimed to comprehensively relate all of the components of metabolic dysregulation to cognitive function and brain magneti...

Web environments provide learners with a great amount of information and various environments and opportunities that they can use to navigate, yet problems may occur as a result of the abundant choices and flexibility provided by these Web-based environments. Among these problems disorientation and cognitive overload in hypermedia are important bottlenecks. But recently emerging semantic web is...

Spectrum sensing is a fundamental component in cognitive radio. New sensing methods are proposed based on the principal component values of the received signal at the secondary users. In particular, two sensing algorithms are suggested, one of the algorithm is based on the ratio of the principal component’s maximum eigen value to principal component’s minimum eigen value called as Maximum Minim...

The Relationship between Cognitive Emotion Regulation Strategies, Emotional Creativity, and Happiness among Primary School Teachers M. Shabanpour M. Hafezian, Ph.D. This research was undertaken to identify the relationship between cognitive emotion regulation strategies, emotional creativity, and happiness. The research method was correlational and the statistical population in...
