Your Guide to NeuroTracker Scores | NeuroTracker - 0 views

  • A landmark NeuroTracker study published Nature Scientific Reports showed that elite athletes have brains with superior capacities for learning, which could be a critical factor as to why they can achieve such high levels of performance on the sports field. Professor Faubert, the inventor of NeuroTracker explained the meaning of this for world-class athletes, “The fact that they are there…is because they are more plastic.  I think that’s one of the criteria.  You would think that this brain is optimal at the highest competitive level, that it’s reached its maximum potential.  But maybe they are there because they can acquire new potential so much more rapidly and so more efficiently.” Neuroplasticity is also known to be a key factor in brain health, with reduced plasticity being a related factor for increased risks of cognitive conditions such as dementia in older populations.
  • The NeuroTracker score itself is established in the neuroscience literature as a high-level measure of attentional capacity.  This means that the higher your score is, the better your attention.  It’s a high-level measure because performing NeuroTracker requires using and integrating several different types of attention.
  • Distributed or Divided Attention – similar to multi-tasking, tracking several targets at the same time requires allocating attentional resources separately to each individual target.

  • Selective Attention – because there are many decoys vying for your attention, selective attention is required to focus attention away from the ‘distractors’ and keep it fixed on the real targets.
  • Sustained Attention – mental focus must be distributed continuously across time, a split second lapse and the targets will be lost.
  • Attention Stamina – concentration must be maintained across twenty mini-tests per session, and across different sessions when performing them back-to-back.
  • NeuroTracker speed thresholds have been shown through many research studies to correlate with other high-level cognitive functions, including executive functions, working memory and processing speed.  They also correlate with many areas of human performance, for instance, one study showed that score predicted on-court performance statistics of NBA players across a season.

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.

  • post‐mortem cellular studies of human brains have revealed an extended period of development, in particular in the frontal and parietal cortices.
  • The term executive function is used to describe the capacity that allows us to control and coordinate our thoughts and behaviour (Luria, 1966; Shallice, 1982).
  • These skills include selective attention, decision‐making, voluntary response inhibition and working memory. Each of these executive functions has a role in cognitive control, for example filtering out unimportant information, holding in mind a plan to carry out in the future and inhibiting impulses.
  • Behavioural studies show that performance of adolescents on tasks including inhibitory control (Leon‐Carrion, Garcia‐Orza, & Perez‐Santamaria, 2004; Luna, Garver, Urban, Lazar, & Sweeney, 2004a), processing speed (Luna et al., 2004a), working memory and decision‐making (Luciana, Conklin, Cooper, & Yarger, 2005; Hooper, Luciana, Conklin, & Yarger, 2004) continues to develop during adolescence.
  • Different aspects of executive function, therefore, may have different developmental trajectories.
  • prospective memory continues to develop during adolescence, in line with the notion of frontal maturation in the brain. It is possible that the lack of improvement in performance between the 10‐ and 14‐year‐olds was related to their pubertal status.
  • The results suggest that there is a dip in performance on this kind of task at the onset of puberty.
  • The researchers linked this pubertal dip in performance to the proliferation of synapses that occurs at the onset of puberty.
  • the sudden proliferation of synapses that occurs at puberty results in a perturbation of cognitive performance.
  • In addition to neural development, there are major changes in hormones at puberty. While it is impossible to tease apart all of the important influences on the social and emotional behaviour of adolescents, significant neural development and hormonal changes are likely to influence social cognition.
  • Perspective taking is the ability to take on the viewpoint of another person. The ability to take another's perspective is crucial for successful social communication.
  • Functional neuroimaging studies have revealed that the parietal and frontal cortices are associated with making the distinction between 1PP and 3PP at the motor (Ruby & Decety, 2001), visuo‐spatial, (Vogeley et al., 2004), conceptual (Ruby & Decety, 2003) and emotional (Ruby & Decety, 2004) level.
  • It is proposed that ‘mirror neurons’ that fire when an agent both performs an action or observes another person performing the action provide a basis for integrating perceptual, motor and social functions (see Rizzolatti, Fogassi, & Gallese, 2001 for review).
  • Several neuroimaging studies have implicated the inferior parietal cortex in the distinction between the self and others at the sensorimotor level (Blakemore, Wolpert, & Frith, 1998; Farrer & Frith, 2002; Ruby & Decety, 2001).
  • hese data suggest that development of social perspective taking undergoes a perturbation during puberty in parallel with the discontinuous processes of brain maturation.
  • Cognitive processes that depend on the prefrontal cortex might undergo a perturbation at puberty due to the synaptic reorganisation that occurs at this time.
  • The greater and more diffuse activity in the dorsal region of the prefrontal cortex in children suggests that there is a heavier dependence on this region in children compared with in adults. The researchers suggested that during adolescence, the network recruited for this task is modified until adulthood, at which stage activation of a smaller, more focal region of the prefrontal cortex is used to perform the same task.
  • Thus, reaction times and imaging data together suggest that in children, an immature stage of the brain where excess synapses, possibly as a result of a burst of proliferation, accounts for the poorer performance and extensive and less efficient frontal activation. A pruned and more myelinated adult brain could explain the faster reaction times and focal activation of the frontal cortex, the area associated with generativity (Frith, Friston, Liddle, & Frackowiak, 1991) and the inhibitory response (Konishi et al., 1999).
  • One possibility is that extensive activation in children is a compensatory strategy used while the brain is less efficient in integrating executive functions.
  • To explain risky behaviour commonly associated with adolescence, the authors postulated that adolescents are driven to seek more extreme incentives to compensate for low recruitment of motivational brain circuitry.
  • It was proposed that when confronted with a risky scenario, adults’ relatively efficient responses were driven by mental images of possible outcomes and the visceral response to those images, in line with the somatic marker hypothesis (Damasio, 1996). However, adolescents relied more on reasoning capacities and therefore activated the DLPFC, hence the relatively effortful responses compared to adults.
  • Neural plasticity of the developing brain may underpin different propensities for learning new skills, such as problem solving, at different stages of the life cycle.

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.

  • Psychology of Individual Differences: Intelligence and Personality in Action. Chapter 2: The Nature of Intelligence
  • This chapter showsthat intelligence, defined as “a very general mental capability that involves the ability to reason, plan, solve problems, think abstractly, comprehend complex ideas, learn quickly, and learn from experience” (Gottfredson, 1997) is at the centerof the cosmos composed by a range of psychological factors(Figure 1).Figure 1. The Psychological Cosmos.
  • Nevertheless, finding the most likely‘structure’ of human personality (including intelligence) based on behavioural differencesmeasured by standardized tests,is just the first stepof a long and fascinating voyage.The identified elements,or factors,that define the ‘structure’ of human personality follow a given ‘dynamic’ and they may be rooted in human‘biology’.

  • The Self Regulation Questionnaire (SRQ) was found to be a valid and reliable tool which measures unique psychosomatic abilities. Self regulation deals with competence and autonomy and can be regarded as a problem solving capacity in terms of an active adaptation to stressful situations to restore wellbeing. The tool is an interesting option to be used particularly in complementary medicine research with a focus on behavioural modification.

Physical activity, diet and other behavioural interventions for improving cognition and... - 0 views

  • Despite the large number of childhood and adolescent obesity treatment trials, we were only able to partially assess the impact of obesity treatment interventions on school achievement and cognitive abilities. School and community‐based physical activity interventions as part of an obesity prevention or treatment programme can benefit executive functions of children with obesity or overweight specifically. Similarly, school‐based dietary interventions may benefit general school achievement in children with obesity. These findings might assist health and education practitioners to make decisions related to promoting physical activity and healthy eating in schools. Future obesity treatment and prevention studies in clinical, school and community settings should consider assessing academic and cognitive as well as physical outcomes.
