ok i'm new to the forum, there is a mass amount of intelligence here i have seen over the past few days reading. this is my first college biology class, and i am probably going to major in zoology because of a strong passion for understanding anima... ha oh yes back to the point.. we have to turn in a proposal of some sort of what we want to do for an experiment so this is what i came up with so far. for all the brains here i am sure you will find many faults, but i want to hear any comments please. this is still an entirely incomplete idea but i think its a strong base to work from. i actually got the idea of hanging the food off the floor from someone who posted in a thread i am sorry i cannot remember the name of you. any ideas to modify or add, subtract from what i have already LET ME KNOW! i want to get awesome grades and you fellows can help me out. thanks! Canine Memory problem: To see how my dog holds memory of the day before (or how he is remembering of food not always being where it was). See if time levels drop over time as the experiment is repeated, also note time between two foods getting shorter experiment: Get string and hang chicken in room 4 feet from the ground when subject is not around. Bring him in, and instinctively I believe he will head for the floor, seeing as the scent is fresh it won’t be very distinct as to where it is. I will track the time it takes for him to find the treat. Then I will repeat the test no more than 5 minutes later with another food object put in the same spot to see if he relates treat to place no matter what the smell, or if a new smell will make him look over the floor again. Track time. Go to new room and do the same test over again. Is he learning that it isn’t going to be on the floor all the time or will he still sniff along while it is suspended over his head the whole time? Track times. Repeat the tests for 5 days. Do the times get any shorter? Is there a relation in the associating of two foods being in the same place? Modified Chi formula for determining correlation x= first food time-second food time Ex: 10 ------------------------------ = ------ = .25 first food time 40 A way to tell is using a modified chi2 test to see if the times get shorter between the two foods in relation to the times of earlier days. The reason being is if say the first day it takes 40 seconds (first treat) and 30 seconds(Second food) that is a 10 second difference, or 1/4 the time cut off. If by the third day he gets it in 10 seconds and 6 seconds that is only a 4 second difference, but that is 2/5 the time cut off. 1/4, or 25% decrease in time between findings is a substantial difference from the 40% decrease in time by the last day of testing, seeing as anything over 5% difference should be considered substantial. This means there is a correlation between him noting that there is a smell no matter what it is, and that this is where the food could be so lets look up too. Or is he is just adapting to food being there? The question still lies: for him is it memory or instinct that makes the times shorter between two foods(supposing there will be shorter times)???
