2. State the problem
The main question is that qre humans’ senses sharper than animalistic organisms or does animalistic organisms’ sense have higher advantages?
3. State your hypothesis
My hypothesis for this research is that dogs’ senses are much keener than humans’ senses, more specifically sight, smell, and taste. In addition, the dog subject will react accordingly to the stimuli quicker than human subject’s reactions.
4. Conduct an experiment to test your hypothesis. Collect data and analyze the results of your experiment
I selected three general senses …show more content…
I decided to use nail polish and nail polish acetone to get proper timed reaction. The human subject’s eyes were closed and as she sniffed the substances, it took her approximately 11 seconds to respond. On the other hand, the dog subject’s reaction rate was approximately 4 seconds. She backed away from the odorous substances and continues to avoid it.
The third and final stimulus was related to Taste. I only did one edible substance that I could receive proper reactions from both subjects, which is lemon. The human subject’s eyes were closed in this stimulus as well. She tasted the lemon and immediately reacted, about 2 seconds. For the dog subject, I squeezed the lemon into the mouth. Surprisingly, it took awhile (7 seconds) until she finally backed away and started rolling around the floor to eliminate the sour taste sensation in the mouth.
According to the experiment and linking it to my hypothesis, the dog subject maintained to performed 2 out of 3 senses stimuli quicker than human subject. The taste stimulus is a shocker for me since dogs have higher number of taste bud cells than humans. It’s most likely due to slower response and unsure of how to react to the sourness of lemon. The sour taste character is most likely not familiar for …show more content…
Discuss your results and if they support or refute your hypothesis
Sight
Due to having a dark setting for the sight stimulus, I researched if dogs have a “night vision”. They actually do, it’s called Tapetum Lucidum, which is a reflective layer in the eyes. It reflects light back into the receptor cells of the eye, which help improve their vision. Dogs usually don’t have good eyesight, however, they could detect the motion better than humans. Sign language is considered as motion movement language and I believed that what help the dog subject to perform better in this stimulus. Additionally, dogs’ low-light vision is much better than human’s, which gave the dog subject an advantage. Humans doesn’t necessary have “night vision”. We could still somewhat see in the darkness, but it takes about 30 minutes for our eyes to fully adjust to the darkness. I didn’t give the human subject a chance to adjust her eyesight. However, I noticed that she started to perform better as time progressed.
Also, dogs’ pupil is much larger than humans, which indicate that dogs have receive more lights/photoreceptors and also have higher proportion of rods in their eyes than humans. Those add to their sight ability in the dark.
