Thinking with their trunks: scientific summary “In the present study, we aimed to better our under- standing of how elephants use their sensory abilities in a food- finding task. First, we sought to determine whether elephants are able to locate food in a two-way object choice task by either audition or olfaction. If significant results were obtained in either domain, the second aim of our study was to investigate whether elephants can use these senses to make choices by exclusion.” (Plotnik, et. al.)
Main point: curiosity was sparked in the minds of the researchers when it was observed that the only experiments performed were on small primates and tested visual and hearing domains, but in non-primates only visual domains were tested in regards to finding food while taking into account “non-rewards”- so they tested on elephants for their extreme smelling senses. In experiment 1 (February to March 2012,) seven elephants at the Think Elephants International research facility at GTAEF in Thailand. To test acoustic cuing, researchers set up two buckets, one filled with …show more content…

This time, the translucent buckets had 2 small holes on their lids and then were placed inside of larger metal baskets. Then there was a smaller orange bucket placed inside of the translucent bucket that contained the reward, which this time instead of just sunflower seeds, it was sunflower seeds mixed with pineapple. During the test experiment the bucket was baited with the lid secured so the elephant was only allowed an “investigation phase,” then the lids were opened and the elephants were allowed to choose called the “choice phase.” This went on for four sets of 10 experiments. The control was basically identical to the experimental test other than instead of two holes in the lids, there were none. The lids were just removed after the first
