Anoura geoffroyi hovering in front of pattern while drinking from feeder. Note long tongue extending into sucrose solution. A 20 watt white fluorescent bulb was centered 42 cm behind the frosted glass diffuser. Water dispensers protruded through holes in the clear plastic imme- diately below each pattern rather than at its center. During experiments with Carollia, each glass feeder was replaced by a melon ball (ca. cm in diameter) attached to a cork which fitted into the hole at the center of each pattern. Commercially available frozen melon balls were thawed and washed in water to remove excess packing syrup. Some were then soaked in an aqueous sucrose solution to be used as positive reinforcement; others were soaked in an aqueous quinine-sodium chloride solution to serve as negative reinforcement. Since the melon balls were somewhat irregular in shape, they were periodically replaced during each series of trials to prevent the bat from associating a particular one with reward or punishment. Olfactory controls were accomplished by occa- sionally placing sucrose treated melon balls at both patterns after washing the surface of the Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Marine Biological Laboratory (Woods Hole, Mass. ); Marine Biological Laboratory (Woods Hole, Mass. ).
