Stimuli: Definition & Examples A tropism is a response that an organism makes to a stimulus. An example of a common tropism in plants is phototropism (or light response). Plants grow towards light sources, and if the direction of light is changed, the plant will also change its direction of growth to accommodate for survival.

Difference Between Stimulus and Response • Stimulus is the first event that takes place, and the response is the result. • A stimulus could be of any magnitude, but the response could never go beyond the highest capability of an organism. • Stimulus cannot be always controlled, especially the external stimuli, whereas response could be controlled.

Stimulus (psychology) In behaviorism and related stimulus–response theories, a stimulus constitutes the basis for behavior, whereas it constitutes the basis for perception in perceptual psychology.n this context, a distinction is made between the distal stimulus (the external, perceived object) and the proximal stimulus (the stimulation of sensory organs). In contemporary experimental psychology the term stimulus is usually used to describe the event or object to which a response is measured.

stimulus Something that causes a response in a body part or organism. A stimulus may be internal or external. Sense organs, such as the ear, and sensory receptors, such as those in the skin, are sensitive to external stimuli such as sound and touch.timulus. n, pl-li (-ˌlaɪ; -ˌliː). 1. something that stimulates or acts as an incentive. 2. (Physiology) any drug, agent, electrical impulse, or other factor able to cause a response in an organism.

Sensory systems - The Human Physiology Stimulus energy is first transformed into graded or receptor potentials and the process by which a stimulus is transformed into an electrical response is called stimulus transduction. Each receptor is specific to a certain type of stimulus, which is called its adequate stimulus. Specificity also exists in the range of stimulus energies that the receptor responds to. However, a receptor can be activated by a nonspecific stimulus if its intensity is sufficiently high.

"What does the latin word ""alum"" mean? Aluminum was derived from the Latin word ""alumen.""?" Best Answer: Alum is the name of a plant, commonly called comfrey. Alumen means alum, which is a number of different metal compounds, crystallized double sulfates, which can contain many different kinds of metals, of which aluminium is one. The name was given to it by the scientist, Sir H. Davy, who isolated it.

Stimulus (physiology) The light from the lamp (1.) functions as a detectable change in the plant's environment. As a result, the plant exhibits a reaction of phototropism--directional growth (2.) toward the light stimulus. In physiology, a stimulus (plural stimuli) is a detectable change in the internal or external environment. The ability of an organism or organ to respond to external stimuli is called sensitivity. When a stimulus is applied to a sensory receptor, it normally elicits or influences a reflex via stimulus transduction.

- A conditioned stimulus (in classical conditioning) is a neutral stimulus paired with a unconditioned stimulus (like food). Eventually, the neutral stimulus could become a conditioned stimulus and produce a different version of the unconditioned response, called the conditioned response.

- Our environment is constantly changing, and in order for us and other living things to survive those changes, we must be able to respond to them. Any detectable change in the environment is called a stimulus. Usually, a stimulus is a product of change in an energy source or force, such as light, or sound, or heat.As humans, we detect and respond to stimulus in order to survive.timuli and responses are not only associated with the external environment, but are also found in the internal environment of organisms as well. Any stimulus within the body of the organism must be detected as well in order for the organism to survive.
