What is a control mechanism that responds to a stimulus by decreasing its intensity called?
There are two kinds of feedback in the control of the body. Negative feedback occurs when a change happens in the body that makes the body beyond it's homeostatic level. Negative feedback reverses those changes and returns the body back to it's normal stage. Positive feedback occurs to temporarily amplify or enforce the change that is occurring. This process causes a number of increases until a signal is sent to the brain to stop the process.
What else can I help you with?
When the initial stimulus produces a response that reinforces the stimulus the mechanism is called?
positive feedback
Responding to stimuli that are similar but not identical to a conditioned stimulus is called?
Generalization. This occurs when an organism responds to stimuli that are similar to the original conditioned stimulus that was paired with the unconditioned stimulus.
Receptors provide information about the intensity of a stimulus through?
Receptors provide information about the intensity of a stimulus through the frequency of action potentials they generate. Higher intensity stimuli result in higher frequency of action potentials being sent to the brain, signaling a stronger stimulus. This frequency coding allows the brain to interpret the intensity of stimuli.
What can increase a strong stimulus?
Increasing the intensity or frequency of the stimulus can strengthen its effect. Additionally, increasing the novelty or relevance of the stimulus can also enhance its impact. Finally, pairing the stimulus with a reward or reinforcement can make it more powerful.
How does the brain perceive the intensity of a stimulus?
There are a number of different ways that the brain perceives stimuli. If a person is hurt, the brain sends a reaction to the body. If something good happens, the brain sends good reactions to the body.
What organism responds to such as light?
An organism responds to a stimulus.
What is a singnal to which an oranism responds?
Stimulus
When an initial stimulus produces a response that exaggerates stimulus called what mechanism?
Exaggerating the stimulus is also seen as amplifying the stimulus. This is seen in outer ear hair cells.The mechanism you refer to is probably a positive feedback mechanism: more of the stimulus causes more of the stimulus. This is in contrast to a negative feedback mechanism, whereby more stimulus results in processes that strive to attenuate (lessen) that stimulus.
What does ampu mean in first aid?
AVPU is level of consciousness; a is alert, v is responds to verbal stimulus, p is responds to pain stimulus; and u is unresponsive.
When the initial stimulus produces a response that reinforces the stimulus the mechanism is called?
positive feedback
What is meant by coding of stimulus intensity?
Threshold
Responding to stimuli that are similar but not identical to a conditioned stimulus is called?
Generalization. This occurs when an organism responds to stimuli that are similar to the original conditioned stimulus that was paired with the unconditioned stimulus.
What cannot be used for signaling the intensity of a stimulus?
Color perception cannot be used for signaling the intensity of a stimulus, as it is primarily used for distinguishing different wavelengths of light. Other sensory modalities such as touch, taste, and smell are better suited for detecting and signaling the intensity of a stimulus.
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).
What does stimulus intensity mean?
Stimulus intensity refers to the strength or magnitude of a stimulus that is perceived by an individual. It can apply to various types of stimuli, such as light, sound, or touch, and influences how the stimulus is experienced. Higher intensity usually leads to a stronger perception or reaction, while lower intensity may be less noticeable. This concept is important in fields such as psychology and sensory perception, as it helps to explain how organisms respond to their environment.
What is the type of feedback where the net effect is that the output of the system shuts off the original stimulus or reduces its intensity?
In a negative feedback loop, the output of the system decreases the intensity of the stimulus.
Receptors provide information about the intensity of a stimulus through?
Receptors provide information about the intensity of a stimulus through the frequency of action potentials they generate. Higher intensity stimuli result in higher frequency of action potentials being sent to the brain, signaling a stronger stimulus. This frequency coding allows the brain to interpret the intensity of stimuli.
