Generic Zantac (Ranitidine, Zantac® equivalent)
Ranitidine is in a group of medications called histamine-2 blockers. Ranitidine works by reducing the amount of acid your stomach produces. Ranitidine is used to treat and prevent ulcers in the stomach and intestines. It also treats conditions in which the stomach produces too much acid, such as Zollinger-Ellison syndrome. Ranitidine also treats gastroesophageal reflux disease (GERD), and other conditions in which acid backs up from the stomach into the esophagus, causing heartburn.

AGE AND BEHAVIOR: LEARNING AND PERFORMANCE - TASK MEANINGFULNESS - PERSONAL RELEVANCE AND TASK DIFFICULTY - EXAMPLE OF "TASK INVOLVEMENT"
A more direct example of "task involvement" was reported by Hulicka (1967). She attempted to teach a paired-associate task in which response words such as INSANE, were paired with stimulus letters such as TL. Hulicka reported that the attrition rate of elderly subjects (65-80 years) reached 80 percent. "Many refused ... to exert themselves to learn 'such nonsense and others complained they could not read the small print . . ." (Hulicka, 1967, p. 181). The older subjects found the task very difficult.
Accordingly, Hulicka changed the task and made it more meaningful. Instead of letters such as TL, the stimulus components were occupations, such as BANKER. Surnames of four or five letters were the response associates, as, for example, MILL and SLOAN. When the task was so changed, the older people carried it out readily. As in the poison-food study by Arenberg, however, the performances of the older subjects were not as good as those of the younger controls.
One aspect of Hulicka's report needs to be emphasized—an aspect which is implicit in all considerations of stimulus meaningfulness. By changing the task from paired associates such as TL-INSANE to BANKER-SLOAN, the task was not only made more meaningful or relevant, it was also made easier. It was made easier for both young and old; it is possible that what Hulicka reported was simply that difficult tasks more readily distinguish between the performances of the young and the old than do easy tasks. The goal, therefore, in comparing tasks of different meaningfulness or personal relevance is to do this while keeping constant their levels of difficulty. Recognizing that it may not be possible to accomplish this completely because personal relevance, in part, defines task difficulty, a study described shortly (Wittels, 1972) demonstrates that an approximation in achieving this goal is possible.
