Bottlebrush trees grow best from semi-hardwood cuttings, which are gathered in mid-to late summer after the current seasons' growth has ripened but not fully hardened. The cutting should be roughly 4 to 8 inches long with a straight, 1/4-inch-thick stem, at least two sets of leaves at the tip and lightly striped bark.
conditioned stimulus. Definition: in classical conditioning, an originally irrelevant stimulus that, after assocation with a US, comes to trigger a conditioned response Researcher: Ivan Pavlov Example: the previously neutral tone stimulus that now triggered the conditional salivation.î î î.efinition: in classical conditioning, a stimulus that unconditionally (naturally and automatically) triggers a response Researcher: Ivan Pavlov Example: food in mouth automatically triggers the salivary reflex.
Usually, the conditioned stimulus (CS) is a neutral stimulus (e.g., the sound of a tuning fork), the unconditioned stimulus (US) is biologically potent (e.g., the taste of food) and the unconditioned response (UR) to the unconditioned stimulus is an unlearned reflex response (e.g., salivation).lassical conditioning differs from operant or instrumental conditioning: in classical conditioning, behavioral responses are elicited by antecedent stimuli, whereas in operant conditioning behaviors are strengthened or weakened by their consequences (i.e., reward or punishment).
