Something that triggers a response. For example, touching a hot surface would be the stimulus to remove your hand from that surface.

an internal or external event which generates nervous system activity or response.

Something that activates or excites the nerve and results in an impulse.

something intended to cause a response

A physical or chemical change that induces some response, e.g. muscle contraction, glandular secretion, nervous reflex action, etc.

anything that evokes a reaction.

Plural: stimuli. An environmental change that is detected by a living organism's sensors and directly influences its activity, such as evoking muscular contraction or glandular secretion.

An Event to a Role Model that activates certain associated behaviour ,the response . source: EU-P103 - ST1.3 domain: General usage: EU-P103

Something causing a response; something in the environment detected by a receptor.

Something that makes a nerve receptor trigger an electrical impulse in a nerve pathway, leading to a change in activity. For example, anything that is seen is a visual stimulus; anything that is heard is an auditory stimulus.

Any form of stimulus energy that can be detected by the body, requires Sensory Transduction

a change that brings about a RESPONSE

something that elicits a response by one of our sense organs.

()-- an environmental event or action that incites, provokes or quickens action. Generally, a stimulus occurs before a response, and sets the occasion for, evokes, or causes an operant response to follow. With respondent behaviour, a stimulus elicits the response. From the Latin meaning "a goad" (a goad was a stick with a pointed end that the ancient Romans used for driving cattle). A component of the Does Equation, a stimulus is functionally related to a movement cycle.

anything that causes a neuron to react. Sometimes the stimulus is so small, that the neuron does not fire (does not send information) and the person does not "feel" anything or react to the stimulus.

Anything that arouses action in the muscles, nerves or other excitable tissue.

Anything that provokes behavior.

Something that activates a sensory receptor and produces a response.

A physical or chemical change in the environment that leads to a response controlled by the nervous system.

Anything that elicits a physiological or behavioral response; see conditioned stimulus.

Something that triggers (starts) a response. A stimulus is often information received through the senses. (TG)

Anything that elicits or evokes action in a person or creates a response in a muscle, nerve, gland or other excitable tissue or organ of the body.

An environmental event capable of being detected by sensory receptors.

something that rouses or evokes a physiological response, or a specific functional reaction in organ or tissue.

Anything in the environment that the organism can detect and respond to.

An environmental change that produces a change in cellular activities; often used to refer to events that alter the transmembrane potentials of excitable cells.

Something causing or regarded as causing a response.

An input signal, which may be an input voltage, digital bit pattern, etc that is used to excite a UUT, and stimulate a response which is measured or detected at the output.

something that causes a response; a sense impression that sets off a reaction in the nervous system - for example, light, heat, sound, gravity, smell, taste, or temperature. The plural is stimuli. Humans as organisms

Any object or action that penetrates awareness or excites an animal to respond.

An agent, action, or condition that elicits or accelerates a physiological or psychological activity or response.

A physical object or environmental event that may have an effect upon the behavior of a person. Some stimuli are internal (earaches pain) while others are external ( a smile from a loved one.)

In physiology, a stimulus is a detectable change in the internal or external environment.

The passing of information from one instance to another, such as raising a signal or invoking an operation. The receipt of a signal is normally considered an event. See: message.

An unclarified word, even for most of its keyword uses in psychology. The possibility of an adequate transactional specification for it will be a critical test of transactional construction. The indicated method of procedure will be through the thorough-going substitution of nouns of action such as "stimulation" in place of substantive nouns such as "stimulus" is usually taken to be.

Any information coming into the body that is capable of generating a nerve impulse.
