INTELLIGENCE AND ENVIRONMENT

Despite what many people think, your social environment can also play an important role in the development of your intelligence. Geniuses aren’t only born – they can be made too. Certainly, you are born with a certain amount of intelligence and you may never achieve the intellectual abilities of someone else born with a different set of genes but equally, poor social nurturing can mean that you may never full realise the potential in your own genes.
The Heritability of IQ
It is widely accepted that intelligence is a trait that is passed down through the generations and the degree to which the intelligence quotient (IQ) is dependent on your genetic background has been extensively researched. For example, several traits are known to be primarily genetic, such as adult height or eye colour whereas other traits have low heritability, meaning that they are heavily influenced by the environment – such as depression in men. The way this is measured is by seeing how much a certain trait var…

EXAM PHOBIA(Fear)

How to overcome exam phobia

It is a common experience of my teaching that more than 60 per cent of students suffer from an examinations phobia.It doesn't matter whether the student is intelligent or not. They all worry about forgetting or overlooking something or the other while appearing in an exam, not being able to recall important facts at the appropriate time and, most importantly, ending up with a low score or failing.

Being focused on that, they highlight the same for the students as well like emphasiszing the need to complete much of the syllabus before the exams, working on important to…

SLEEP AND MEMORY

Why do we need sleep?
A lot of research and theories have been thrown up over the years. Scientists have shown numerous ways in which sleep is related to memory. Working memory was shown to be affected by sleep deprivation. Working memory is important because it keeps information active for further processing and supports higher-level cognitive functions such as decision making, reasoning, and episodic memory. As the field of sleep research is still relatively new, scientists have yet to determine exactly why people sleep. However, they do know that humans must sleep and, in fact, people can survive longer without food than without sleep. And people are not alone in this need – all mammals, reptiles and birds sleep.
Scientists have proposed the following theories on why humans require sleep:
• Sleep may be a way of recharging the brain. The brain has a chance to shut down and repair neurons and to exercise important neuronal connections that might otherwise deteriorate due to lack …
