Assuming you are referring to the different types of "environmental stimuli," as in Biology, the answer would include many sources. All living things (organisms) respond to environmental stimuli; this is one of the seven key characteristics of living things (including evolution, order, regulation, growth and development, reproduction, and energy utilization). So, for example, our bodies can respond to physical damage by making us aware of it through our feeling of pain. The "fight or flight" response can be triggered by threatening environmental stimuli. Or, a Venus fly trap will snap shut when an insect lands in its trap.

Stimulus occurs in the external environment and is detected by sensory receptors in the body. These receptors then send signals to the brain to process and interpret the stimulus.

What must be paired together for classical conditioning to occur?

For classical conditioning to occur a neutral stimulus must be paired with an unconditioned stimulus. The neutral stimulus is initially meaningless to the organism but becomes associated with the unconditioned stimulus after the two are repeatedly paired together. This process of association is known as classical conditioning. The following are the components needed for classical conditioning to occur: A neutral stimulus An unconditioned stimulus A response ReinforcementThe neutral stimulus is something that does not initially produce a response. It is usually a sound taste or smell. The unconditioned stimulus is something that naturally produces a response. It is usually a food or something that causes pain or discomfort. The response is the reaction to the unconditioned stimulus such as salivating or flinching. Reinforcement is the use of rewards or punishments to strengthen the association between the neutral stimulus and the unconditioned stimulus.


When is operant stimulus control achieved?

Operant stimulus control is achieved when a behavior consistently occurs in the presence of a specific stimulus due to its history of reinforcement or punishment. This means that the behavior is more likely to occur when that stimulus is present and less likely in its absence.


What is the occurrence of a learned response to stimuli that are similar to the original stimulus is called stimulus?

Generalization. It refers to the tendency for a learned response to a specific stimulus to occur in the presence of other stimuli that are similar to the original stimulus.


Is it true that High-stimulus elections occur only during periods of realignment?

true


What is a somatic reflex and how does it occur through the CNS?

A somatic reflex is where the body responds to stimulus. The message from the stimulus is sent through the central nervous system via the spine, and from there it travels to the brain.


What is transient current?

Transients can be currents or voltages. They occur momentarily and fleetingly in response to a stimulus or change in the equilibrium of a circuit.


What occurs without an outside stimulus when reactants come into contact with each other?

A spontaneous reaction will occur without an outside stimulus if the reactants have enough energy to overcome the activation energy barrier. This can lead to the formation of products and release of energy.


How do you spell stimulus?

'Stimulus' is the correct spelling.


Which of the following events occur during late ventricular diastole?

do not require an external stimulus to reach threshold, while other cardiac cells do.


What is the amount of time it takes a person to perceive a stimulus an react to it?

It typically takes about 0.25 to 0.5 seconds for a person to perceive a stimulus and react to it. This includes the time it takes for sensory information to travel to the brain, for the brain to process the information, and for the response to travel back to the muscles. Variations in reaction time can occur depending on the individual and the complexity of the stimulus.


What is the different between an external stimulus and an internal stimulus?

The difference between an external stimulus and an internal stimulus is that an external stimulus is a stimulus that comes from outside an organism. But an internal stumulus is a stimulus that comes from inside an organism. An example for an external stimulus can be that when you are cold, you put on a jacket. An example for an internal stimulus is that when you feel hungry, you eat food.


What are the four characteristics of a stimulus in stimulus coding?

The characteristics are modality (type of stimulus), intensity (strength of stimulus), duration (length of stimulus), and location (where the stimulus occurred).
