money google ads freebies blogging









well, I do see lots of google adsense ads for clicking but they yield zilch for this blog although photography tips does better.

It's a mystery to me.


Why should I create an avenue for ads, with a commercial interest for free, it seems google has hit the pits, or is it just me?

The Science Behind Lumosity
Neuroplasticity: how the brain is capable of changeScientists have historically believed that once a person reaches adulthood, their cognitive abilities are immutable. But beginning in the early twentieth century, that theory has been contested by evidence suggesting that the brain’s abilities are in fact malleable and plastic. According to this principle of neuroplasticity, the brain is constantly changing in response to various experiences. New behaviors, new learnings, and even environmental changes or physical injuries may all stimulate the brain to create new neural pathways or reorganize existing ones, fundamentally altering how information is processed.
One of the most dramatic examples of neuroplasticity at work comes from a 2000 brain scan study on London taxi drivers (Maguire et al., 2000). In order to earn a license, London taxi drivers typically spend about two years learning to navigate the city’s serpentine streets. What mark, the study’s researchers wondered, did this long, rigorous period of training leave on taxi drivers’ brains? Under the scrutiny of fMRI scans, 16 male taxi drivers in this study were revealed to have larger hippocampuses than a control group of 50 healthy males of similar ages. And the longer the time spent as a taxi driver, the larger the hippocampus tended to be. As a brain area involved in memory and navigation, the hippocampus likely changed in response to the taxi drivers’ experiences.
Most instances of neuroplasticity-based changes in the brain are much more subtle. But in recent decades, it’s cases like that of the London taxi drivers that have inspired certain members of the scientific community to pursue the next logical step in research: rather than passively waiting to see how the brain might respond to circumstances, is it possible to direct that capacity for change, targeting improvements in specific key abilities?
The science of cognitive training seeks to answer this question. In 2013 alone, 30 cognitive training studies were registered on the government database ClinicalTrials.gov. Lumosity scientists, with the help of outside collaborators, contribute to this research effort: so far, 7 peer reviewed studies have been published using Lumosity as a cognitive training tool for diverse populations, including healthy adults, cancer survivors, elderly people, and children with a genetic disorder.

The scientific roots of the Lumosity program
Research has found that certain types of activities may impact the brain more than others (Mechelli et al., 2004; Gaser and Schlaug, 2003; Draganski et al., 2006). It’s believed that as an activity is repeated, the brain tends to fall back on the same set of existing neural pathways. To continue changing, the brain must be exposed to novel, adaptive experiences that challenge it to work in new ways.

Drawing on this idea, Lumosity is designed to give each person a set of exercises that challenge their cognitive abilities.

Lumosity “games” are based on a combination of common neuropsychological and cognitive tasks, many of which have been used in research for decades, and new tasks designed by an in-house science team. Working with experienced game designers, Lumosity neuroscientists have transformed these tasks into over 40 challenging, adaptive games.

Lumosity’s game-based training program is designed to expose your brain to gradually increasing levels of challenges, adapting game difficulty to your individual ability level. As your scores increase, you may encounter new or more difficult games. Modelled from the concept of a physical personal trainer, Lumosity pushes you to operate at the limits of your abilities and stay challenged.

lumosity brain games fun gaming









Workouts rely on your brain's innate neuroplasticity, or its ability to change and adapt.


Watch out for your free trial, coming soon.

Lumosity does improve your

Speed
Memory
Attention
Flexibility
Problem Solving


But within those areas it does test your

Information processing and vizualization

and spatial orientation

as well as

working memory, spatial recall , face-name recall and

divided attention, selective attention and timing and field of view

verbal fluency , task switching, response inhibition and

numerical calculation, planning, quantitative reasoning, logical reasoning

if you find these names daunting, there will be games there that you enjoy, accompanied by sounds and range from easy to difficult, but once you get the hang of them you'll love the imagery and quaintness, as you build robots, drive trains, catch animals and so much more.

Whatevr you do, have fun, and your own brain will take care of the rest as you are challenged by your own improvement in your own scores, don't worry about what others do, just do what you like, choose the games and styles that appeal and you'll find there is more to life than just the games you are familiar with.



Keep your eyes open for your free trial, it'll arrive here in due course and all of it scientifically based, all you need do is choose what you like and play on.
