What is the ability to respond to a stimulus?

What is the ability to respond to a stimulus?

Irritability describes the ability to respond to a stimulus.

What is the stimulus your body is responding to?

They detect a change in the environment stimulus. In the nervous system this leads to an electrical impulse being made in response to the stimulus….Receptors.

Sense organ Stimuli receptors respond to
Ear Sound, position of head

Which refers to the ability to quickly respond a stimulus?

Answer: the ability of an organisms to respond to. exterial stimuli is called sensitivity.

What is stimulus response in psychology?

Stimulus Response Theory is a concept in psychology that refers to the belief that behavior manifests as a result of the interplay between stimulus and response. In other words, behavior cannot exist without a stimulus of some sort, at least from this perspective.

Why do we not respond to all stimuli in our environment?

When we are exposed to stimuli, we will react to it, but only for a while, and gradually adapt to it. Our sensors developed the ability to react only to the changes in our environment. If adaptation did not exist, we would constantly react to every stimulus around us.

What is an example of a stimulus and response?

Examples of stimuli and their responses: You are hungry so you eat some food. A rabbit gets scared so it runs away. You are cold so you put on a jacket.

What happens when an electrical stimulus is sent along the central nervous system?

An electrical impulse travels along the first axon. This triggers the nerve-ending of the neurone to release chemical messengers called neurotransmitters . These chemicals diffuse across the synapse (the gap) and bind with receptor molecules on the membrane of the second neurone.

What is a nerve response?

Our nervous system deals with this information and so may bring about a rapid response in the organism. A response is a change in an organism of part of it, produced by a stimulus. It is important to note that it is not actually powered by the stimulus, which merely acts as a trigger.

Is excretion a response to stimulus?

Our body produces and excretes sweat as a response to the hand heating up. Our body wants to maintain homeostasis and as a result we sweat and as the water evaporates we cool down. This is a response triggered by the nervous system to help protect the hand from the heat of the fire.

Is the ability to do things in the shortest possible time?

Speed is the ability to get from one place to another in the shortest possible time. The combination of strength and speed is commonly referred to as power.

What is Pavlov theory?

Pavlov’s Theory of Classical Conditioning Based on his observations, Pavlov suggested that the salivation was a learned response. Unlike the salivary response to the presentation of food, which is an unconditioned reflex, salivating to the expectation of food is a conditioned reflex.

What is stimulus and response?

A change in the environment is the stimulus; the reaction of the organism to it is the response.

Can a stimulus evoke the same response as an unconditioned stimulus?

After an association has been formed between the previously neutral stimulus, now known as the conditioned stimulus (CS), and the unconditioned response, the CS can evoke the same response, now known as the conditioned response, even when the UCS is not present.

How big is the response to a stimulus?

The physiological response to a specific stimulus can be very subtle. In the case of evoked biopotentials, such as those associated with the Auditory Brainstem Response (ABR), some of the associated response waves may have voltage magnitudes on the order of a few hundred nanovolts.

How does stimulus discrimination lead to conditioned responses?

Because of stimulus discrimination, only a very particular sound will lead to a conditioned response. In one well-known experiment on classical conditioning, researchers paired the taste of meat (unconditioned stimulus) with the sight of a circle (conditioned stimulus), and dogs learned to salivate in response to the presentation of a circle.

Which is an example of a conditioned stimulus?

For example, if a bell tone were the conditioned stimulus, discrimination would involve being able to tell the difference between the bell sound and other similar sounds. 1  The classical conditioning works like this: A previously neutral stimulus, such as a sound, is paired with an unconditioned stimulus (UCS).
