Say The Color Not The Word !

Image
This peculiar effect is known as "Stroop Effect" named after J. Ridley Stroop who discovered this in 1930.


Why is it difficult to say the colour ? The words themselves have a strong influence over your ability to say the colour. The interference between the different information (what the words say and the colour of the words) your brain receives causes a problem. There are two theories that may explain the Stroop effect: Speed of Processing Theory: the interference occurs because words are read faster than colours are named.Selective Attention Theory: the interference occurs because naming colours requires more attention than reading words.
I think that this puzzle would be easier for a very young child than for older children or adults. Try  this out on some small kids who know their colours, but cannot yet read! I would imagine that the children would not get confused by this puzzle because the words would not have any meaning to them. They just recognise th…

Why the return trip home feels shorter ?

Image
We have all felt this unique and peculiar phenomena.

A new study has revealed that people reflecting on a roundtrip walk estimated that the return trip took less time than the outward trip.

Many have experienced the "return trip effect," where the return trip seems shorter than the outward trip, even when the trips actually
took the same amount of time.


Ryosuke Ozawa from Kyoto University and colleagues compared a group of 20 men watching two of three pre-recorded walking movies, of either
 an outbound trip and a return trip or two outbound trips.
The participants estimated the length of the two movies both while watching and then again after the two trips.
Only the participants from the group watching an outbound trip and a return trip-a roundtrip-estimated that the second trip took less time than the first trip.

Furthermore, the participants felt the return trip effect only when reflecting on length after the trips.

By comparing the round-trip condition and the non-round-…

Adorable Animals You Din't Know That You Could Have As Pet

Image
Dogs and Cats seems old next to these adorable & exotic animals. You can also bring them home and they are human - friendly. Fennec Fox are the most adorable to keep them as pet. If you want to keep a dog and a cat both, don't think much. Fennec are the best choice. Fennec Fox is a small nocturnal fox mainly found in the Sahara Desert.  Sugar Gliders have become a popular pet.They are small and easy to care. They can glide through air, so they need much space. Sugar Gliders are illegal to keep as pet in some countries. Genet are growing their popularity because their beautiful patterns on them and their behaviour which is more likely to cats and ferrets. But they are more closely to mongoose than cats and ferrets.If you love Big cats (Lions, tigers, leopard and cheetah) and want to kept them as pet but it is impractical to have one. Here is one more option Savannah Cats. In 1959, Soviet Union scientist Dmitri Belyaev set out to breed domesticated silver fox. He was able to br…

List of some Indian inventions that may surprise you !!

Image
Button - Buttons were made from seashell and were used in the Indus Valley Civilization (Now India and Pakistan ) for ornamental purposes by 2000 BCE. Buttons were carved into geometric shapes and had holes pierced into them so that they could be attached to clothing by using a thread.
Ruler - Rulers were made from Ivory and used by the Indus Valley Civilization in 1500 BCE. The  ruler was calibrated to about 1/16 of an inch which is less than 2 millimetres. The weights and measures of the Indus civilization also reached Persia and Central Asia, where they were further modified.Stirrup - The earliest evidence of the stirrup was a toe loop that held the big toe and was used in India late in the second century BC. This ancient foot support consisted of a looped rope for the big toe which was at the bottom of a saddle made of fiber or leather.Stepwell - The earliest stepwells most likely date to about 550 AD, but the most famous were built in medieval times. It is estimated that over 3,00…

Solar-panel windows

A breakthrough in quantum dot research by scientists at Los Alamos National Laboratory paved the way for windows that double as solar panels.Quantum dots - nano-crystals made of a semiconductor - were embedded in a transparent polymer in order to capture the sun's energy and harvest it as power.


Smart contact lenses

A smart contact lens that can monitor the glucose levels of diabetes sufferers was developed by Google in January.Coming out of the company's Google X skunk works division, best known for developing Google Glass, the contact lenses use chips and sensors the size of glitter to offer an early warning to the wearer by analysing tears.

Each thud of a hiker’s heel releases enough energy to illuminate a light bulb. Rather than waste that power, Matt Stanton, an engineer and avid backpacker, created a shoe insole that stores it as electricity.

To save more lives, a group of veterans, scientists, and engineers known as RevMedx has created …

Lazy Lifestyle Led To Weaker Bones

Image
The comparatively light bone structure of modern humans compared to ancestor  and other modern primates may be due to the modern abandonment of the constant physical activity that was inherent in the life of early hunter gathers.

The most plausible explanation is that a lack of constant physical activity causes the bone in the head of the femur, the long bone in the thigh, to become thinner and lighter than that found in more mobile populations or modern primates such as chimpanzees, gorillas and orangutans.
The other two possible explanations, that humans and nonhuman primates have different bone structure because of genetics, with humans evolving to a lighter, more gracile structure, Or that the large joint surfaces required for upright, two-legged movement decrease the strain on bone and therefore the development of strong bones, do not appear to be true.

Ryan, working with Colin N. Shaw of the University of Cambridge, UK, looked at the hip joint to determine which of the three possib…

Antimicrobial Metal :- Copper !

Image
Copper and its alloys (brasses, bronzes, copper-nickel-zinc, and others) are natural antimicrobial materials. Ancient civilizations exploited the antimicrobial properties of copper long before the concept of microbes became understood in the nineteenth century.

Bacteria, yeasts, and viruses are rapidly killed on metallic copper surfaces, and the term “contact killing” has been coined for this process. In several clinical studies, copper has been evaluated for use on touch surfaces, such as door handles, bathroom fixtures, or bed rails, in attempts to curb nosocomial infections. In connection to these new applications of copper, it is important to understand the mechanism of contact killing since it may bear on central issues, such as the possibility of the emergence and spread of resistant organisms, cleaning procedures, and questions of material and object engineering. Recent work has shed light on mechanistic aspects of contact killing.
The antimicrobial properties of copper are still…
