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: PROCESSING SENSE INFORMATION - SEQUENTIAL INTEGRATION - STIMULI REFLECTING COMMON EXPERIENCE - VISUAL FIGURES
It was seen that not all evidence is explained equally well by the stimulus persistence model. In the lifted weight experiment, the model had to be applied in a complicated way and a total support for the model was not actually achieved. With the explanation used, a total support might have been seen had the older group been superior to the younger group in the successive weight comparison condition, rather than not being poorer. A study by Wallace (1956) on visual perception must be interpreted in a manner similar to that of the lifted weight study if the stimulus persistence model is to be applied. In addition, another idea is useful, although perhaps not crucial, in applying the model. This idea will also be used in the next section on the perception of speech. Under certain conditions, if the second stimulus is the same as the first, as in the simple case of CFF, they appear fused. If the two stimuli are similar and do not come too rapidly together, and the two must be compared, the trace of the first can aid in judgments of the second. However, if, as in speech, the new input is different from the old and the two come in close temporal order, comparison is not possible, only a type of fusion. In this case, the fusion makes for confusion. With these ideas, Wallace's data can receive a stimulus-persistence interpretation, although they tax the theory considerably.
Wallace presented, sequentially, visual information to an under-30 age group and to an over-60 age group. She used four groupings of stimuli, varied in complexity. As an example, going from simple to complex, she used a triangle, a five-pointed star, a side-view silhouette of a child walking holding a flower, and, as most complex, a pictorial representation of a policeman holding the hands of two children while walking with them. This latter stimulus included shadows for perspective and a major background item. From simple triangle to a complex picture, Wallace had a wide range of meaningful complexity.
Wallace had each subject look through a narrow opening in a box and, in so doing, the subject could see only a small part of the particular stimulus on display. To start, only the lowest portion of the stimulus was seen, soon the next part above it, and slowly—in the course of two to three seconds—the top part was seen. At any one moment only a small portion of the stimulus was visible, but, in time, the whole of it was successively revealed. Correct identification of the displays depended upon integrating material perceived serially over the period of time.
With the simple stimuli, the performances of the two age groups were nearly equal; with increasing complexity of stimuli, the older subjects were increasingly slower than the young in making correct identifications.
