What does it mean by external stimuli?

An outside stimulation An external stimulus is one that originates from outside of the organism. As an example, if you are cold, you put on a jacket. The jacket is an external stimulus that causes your body to respond by producing more heat.

There are two types of external stimuli: positive and negative. If the cold stimulus was negative, your body would produce more heat to get rid of it. Positive stimuli cause organisms to function differently from how they normally would. For example, eating chocolate causes your body to release dopamine, a neurotransmitter associated with pleasure. This is a positive stimulus that triggers your body to want more of it later.

External stimuli can be anything that affects an organism, including physical, chemical, or biological. An example of a physical stimulus is heat or cold. A chemical stimulus is something that affects an organism's chemistry such as sugar or alcohol. A biological stimulus is something that affects an organism's biology such as a virus or bacteria. Viruses are biological particles that cannot survive outside a living organism; therefore, they are considered external stimuli.

Physical, chemical, and biological stimuli can all affect an organism positively or negatively. For example, hot temperatures are negative factors for humans because they can cause us pain and death. Eating chocolate is a positive factor for humans because it gives us energy.

What is an example of a person reacting to an external stimulus?

2. Temperature is another example of an external stimulation. When it's chilly outdoors, your first instinct is to put on a jacket to stay warm. There must be an internal stimulus if there is an exterior stimulus. An internal stimulus is one that originates within an organism. A cold outside temperature is an internal stimulus that causes you to want to cover up with a jacket.

1. Reacting to an external stimulus is when someone reacts spontaneously without thinking about it first. For example, if you see something scary, you might yell or run away from it because it reacted you by causing you to feel fear. External stimuli can also trigger thoughts and feelings inside you; for example, seeing a blood-splattered wall might make you think about violence against women.

Reacting to an external stimulus is different from expecting something to happen. If you expect something bad to happen but it doesn't, then you have not reacted to the stimulus, but anticipated its outcome.

In psychology, there are two types of reactions: automatic and controlled.

An automatic reaction is one that happens quickly without any thought process. For example, if someone yells at you, it is an automatic response because there was no time to think before you acted. You did not know what would happen if you answered back, so you kept your mouth shut and ran away in fear.

What are the peculiarities of external stimuli?

External stimuli are responses to what is going on around you. You flinch, for example, if someone throws anything at you. You close your eyes if someone flashes a bright light in your face. Stimuli are often easy to understand if you recall that internal refers to feelings and external refers to reactions. Flinching is an internal response; it happens within you. Reaching out to stop something from hitting you is an external response.

Stimuli can be positive or negative. If someone gives you a big smile when they see you, that's a positive stimulus. A frown might be a negative one. Anything that causes you to react in some way, no matter how small that reaction may be, is called a stimulus.

Your body is always reacting to stimuli. When you hear a sound, your body reacts by sending signals to your brain. Your brain then tells your muscles what to do by sending messages through nerves. These messages can be instructions to move or not move parts of your body, say, or they can be signals to feel pain or pleasure.

Your brain is always receiving information from your senses: hearing sounds, feeling touches, seeing colors, tasting foods. This information is passed on to other parts of your mind for processing. Parts of your brain work together every time you use your senses to perceive something.

What is an example of an external stimulus for a human?

External stimuli are changes that occur outside of the body or knowledge that is transmitted to us via our senses. This might be due to cold or hot conditions, low or high light levels, or danger. Internal stimuli are changes in the body's circumstances, such as harmful food in the stomach, infections in the body, or a lack of food or drink. All sensations, thoughts, and feelings are internal stimuli.

The brain is always receiving information from the environment through our five sense organs: sight, sound, touch, taste, and smell. The brain also sends signals to all parts of the body to let it know what is going on around us. These signals are called "neurological impulses" and they are sent through the nervous system. The electrical and chemical messages that control muscle movement are transmitted through nerves. The brain controls these nerves through neurons. Neurons connect with other neurons at special places called synapses. At these connections, neurotransmitters transmit messages from one neuron to another.

Every time we experience something new, learn something new, or do something new, our brains make new connections. These connections are how we grow mentally and emotionally. External stimuli can cause us to make new or change existing mental pathways in our brains. An example of an external stimulus would be if you were raised in a home where violence was never spoken of or shown, then one day you see your neighbor get hit by his wife and then killed right before your eyes.
