Conditioned Stimulus
Conditioned Stimulus a signal that causes a conditioned reflex; it may be any stimulus of an organism’s external or internal environment that is perceived by the sensory organs and that causes excitation in the cerebral cortex. The conditioned stimulus precedes an unconditioned stimulus or coincides with it. Natural conditioned stimuli are used in unconditioned reinforcement; examples are the sight and smell of food. Artificial conditioned stimuli are more varied and do not have a direct relationship to the properties of the unconditioned stimulus; they become positive or negative conditioned signals only when a conditioned reflex is being developed. Conditioned stimuli that are indirect signals of the food-related, defensive, and sexual reflexes are of great importance in the adaptive behavior of animals. conditioned stimulus
stimulus [stim´u-lus] (L.) any agent, act, or influence that produces functional or trophic reaction in a receptor or an irritable tissue.conditioned stimulus a stimulus that acquires the ability to evoke a given response by repeatedly being linked with another stimulus that naturally evokes that response; see also conditioning.depolarizing stimulus a stimulus that lowers the potential" >resting potential, making the inside of a fiber less negative. In cardiac fibers this means bringing the resting potential from −90 mV to −70 mV.discriminative stimulus a stimulus associated with reinforcement, which exerts control over a given type of behavior; the subject must discriminate between closely related stimuli and respond positively only with this particular stimulus.eliciting stimulus any stimulus, conditioned or unconditioned, that elicits a response.threshold stimulus a stimulus that is just strong enough to elicit a response.unconditioned stimulus any stimulus that naturally evokes a specific response; see also conditioning.con·di·tioned stim·u·lus1. a stimulus applied to one of the sense organs (for example, receptors of vision, hearing, touch) that are an essential and integral part of the neural mechanism underlying a conditioned reflex; 2. a neutral stimulus, when paired with the unconditioned stimulus in simultaneous presentation to an organism, capable of eliciting a given response. conditioned stimulusn.
