Explanation:
The blank slate, the dominant theory of human nature in modern intellectual life stating that humans are shaped entirely by their experiences and not by any preexisting biological mechanisms, is being challenged and soundly trounced by the cognitive, neural, and genetic sciences, said Steven Pinker, Harvard University, in his Keynote Address.
“Everyone has a theory of human nature,” Pinker said. “Everyone has to anticipate the behavior of others, and that means all of us have theories, tacit or explicit, about what makes people tick.”

<span>The statement represented above is TRUE. Our perception is the way how of sensory information understands and interprets the environment we remain in. The perception of a human being provides signals right to the nervous system that is a result of stimulation of our sense organs. The basic structure of our perception is developed by these features : learning, memory, expectation, and attention.</span>
Drugs interfere with the way neurons send, receive, and process signals via neurotransmitters. Some drugs, such as marijuana and heroin, can activate neurons because their chemical structure mimics that of a natural neurotransmitter in the body.
Different types of drugs affect your body in different ways, and the effects associated with drugs can vary from person to person. How a drug effects an individual is dependent on a variety of factors including body size, general health, the amount and strength of the drug, and whether any other drugs are in the system at the same time. It is important to remember that illegal drugs are not controlled substances, and therefore the quality and strength may differ from one batch to another. Drugs can have short-term and long-term effects. These effects can be physical and psychological, and can include dependency. You may act differently, feel differently and think differently if you have taken drugs. And you may struggle to control your actions and thoughts. You might begin to use drugs without thinking about any harm to your body. You might think drugs won't become a problem because you are only a casual user. The more you take a drug, the more likely you are to build up a tolerance to its effects. This can lead to the need to take larger doses to obtain the effects of the drug. For this reason, evidence suggests that after prolonged use, many drugs can cause dependence. Drug dependence can quickly begin to affect your psychological and physical health, and can also affect your work and social life. It is important to remember that there is no safe level of drug use. Be careful when taking any kind of drug.
