Overall, the available evidence suggests that fluid cognition is an aspect of cognitive functioning that can be under considerable environmental influence both cumulatively over time and interactively within context in a way that indicates it to be a highly salient influence on behavior, but one that is distinct from general intelligence, psychometrically defined.

A third source of evidence is neuropsychological and concerns the extent to which cognitive impairments in identified developmental disorders are consistent with a pattern of dissociation between fluid cognitive functions and general intelligence.
-
Fluid cognitive functioning can be thought of as allpurpose cognitive processing not necessarily associated with any specific content domain and as involving the active or effortful maintenance of information, whether verbal or visual-spatial in working memory for purposes of planning and executing goal directed behavior (Baddeley 1986; Kane & Engle 2002).

Why is executive function important for teenagers? - 0 views
-
There is a set of mental skills that’s one of the best predictors of a successful life in virtually every way you can measure success. Yet most people don’t even know it exists.
-
It’s called executive function. Usually abbreviated EF, executive function plays a big part in mental health, teaching, parenting – even employment - virtually the entire behavioral food chain of human experience.
-
I define executive function as “the ability to get things done - and not punch someone in the nose while doing it.” Executive function is a set of mental skills that help you get things done. It’s located in the frontal lobe of the brain, and can help you manage time, pay attention, multitask, and more. It’s also involved in a teen’s mental health, which we know is critically important to understand,

Can headphones train you to focus better? - The Verge - 0 views

Posner, a neuroscientist at the University of Oregon who studies memory. Posner has conducted studies showing that even a few days of really good mindfulness meditation can alter the ability of the brain to focus. Physical exercise is also one common intervention that can help, too, especially with elderly people, he says. Meditation is helpful because, unlike “brain games” that train you to pay attention to one thing, its effects can generalize. If you engage in mindfulness meditation, there is evidence that it’ll help you focus better in general, not just be better at playing 2048, according to Giesbrecht.
Mind-Body Practices and the Adolescent Brain: Clinical Neuroimaging Studies.pdf - 1 views

Examples of such practices include yoga postures, meditation interventions, tai chi, qi gong, hypnosis among many others.

As a modality, EEG is limited by its spatial resolution and bias towards detecting synchronized activity. It is unable to detect changes in neurotransmitter levels or brain activity deep in the CNS.
-
Another major drawback to PET and SPECT imaging is that these techniques have generally poor temporal resolution.

Glossary Cognitive function: ↑ The way we process and think about the world around us. Cognitive functions include attention, memory, and ability to solve problems. Neuroplasticity: ↑ Changes that happen in the brain as the result of our experiences. Alzheimer’s disease: ↑ A disease that affects the brain in older age. The main characteristic of Alzheimer’s disease is a problem with cognitive functions, especially memory.
Development of the adolescent brain: implications for executive function and social cog... - 0 views
-
Adolescence is a time of considerable development at the level of behaviour, cognition and the brain. This article reviews histological and brain imaging studies that have demonstrated specific changes in neural architecture during puberty and adolescence, outlining trajectories of grey and white matter development. The implications of brain development for executive functions and social cognition during puberty and adolescence are discussed. Changes at the level of the brain and cognition may map onto behaviours commonly associated with adolescence. Finally, possible applications for education and social policy are briefly considered.
-
Recent MRI studies indicate that the time at which the brain reaches maturity may be much later than the end of adolescence. One such study of participants aged between 7 and 30 revealed that the loss of grey matter in the frontal cortex accelerated during adulthood between the early 20s and up to the age of 30 (Sowell et al., 2001).
-
The non‐linear decrease in grey matter was concomitant with a linear increase in white matter, consistent with earlier MRI data and with post‐mortem studies.

Short‐term Sahaja Yoga meditation training modulates brain structure and spon... - 0 views
-
While cross‐sectional studies have shown neural changes in long‐term meditators, they might be confounded by self‐selection and potential baseline differences between meditators and non meditators. Prospective longitudinal studies of the effects of meditation in naïve subjects are more conclusive with respect to causal inferences, but related evidence is so far limited.
-
Compared with 30 control subjects, the participants to meditation training showed increased gray matter density and changes in the coherence of intrinsic brain activity in two adjacent regions of the right inferior frontal gyrus encompassing the anterior component of the executive control network. Both these measures correlated with self‐reported well‐being scores in the meditation group.
-
The significant impact of a brief meditation training on brain regions associated with attention, self‐control, and self‐awareness may reflect the engagement of cognitive control skills in searching for a state of mental silence, a distinctive feature of Sahaja Yoga meditation. The manifold implications of these findings involve both managerial and rehabilitative settings concerned with well‐being and emotional state in normal and pathological conditions.

The Athletic Dimension of eSports | NeuroTracker - 0 views

He suggests eSports athlete should be following diets similar to those in professional sports, as well as performing regular physical training to support better motor-skills. His thought is that this may extend career time by 5 years or more. “My advice is that gaming is more than just playing video games. It is a complex interaction of many different, mostly cognitive, skills. To improve these skills and guarantee sustainable results, a holistic approach is needed.” In fact now some of the biggest eSports teams are turning to sports science to raise their game, including using NeuroTracker to sharpen their minds. This means that in coming years we’re likely to see cyber athletes pushing the boundaries of human performance.
Psychological Flexibility as a Fundamental Aspect of Health - 0 views

Psychological flexibility spans a wide range of human abilities to: recognize and adapt to various situational demands; shift mindsets or behavioral repertoires when these strategies compromise personal or social functioning; maintain balance among important life domains; and be aware, open, and committed to behaviors that are congruent with deeply held values.

Psychological Flexibility as a Fundamental Aspect of Health Achieving psychological health is one of the foremost goals of human existence.

We are not disputing that positive emotions are important (Fredrickson, 1998), strengths or positive traits are important (Peterson & Seligman, 2004), or that the satisfaction of basic needs for belonging, competence, and autonomy are important (Deci & Ryan, 2000). However, these static approaches fail to capture the dynamic, fluctuating, and contextually-specific behaviors that people deploy when navigating the challenges of daily life.
