Fig. 6. Experiment 5, showing the learning performance as measured by the LI values of individually assayed CS-W larvae from five learning experiments. Experiments use either NaCl only (PURE/NaCl), a combination of FRU and NaCl (FRU/NaCl), FRU only (FRU/PURE), a combination of FRU and QUI (FRU/QUI), or QUI only (PURE/QUI) as reinforcers. Positive LI values indicate associative learning. The box plot represents the median as the middle line and 10 and 90, and 25 and 75% quantiles as whiskers and box boundaries, respectively. ^*P<0.05. The test was performed in a down-sized X-plate assay. Please note the truncated axis. Sample sizes are from left to right N_LI=108, 123, 111, 131, 117.
