You have just been asked to teach the concept of adaptation to apsychology class. You decide to conduct the following experimentsto teach the concept of adaptation.
Task 1: Conduct three of the following experiments. Record yourreactions, and be specific for each experiment.
Experiment 1:
Rub your index fingers gently over a piece of very coarse sandpapera few times and rate its coarseness on a scale from 1 (very soft)to 7 (very coarse).
After a minute or two, rub the same finger over the paper and againrate its coarseness. Did your perception of the coarseness change?How? Record your reaction.
Experiment 2:
Prepare one cup with sugar water and one with fresh water.
Take a sip of the sugar water and swish it around in your mouth forseveral seconds without swallowing it. Gradually, it should tasteless sweet. (Dispose of the sugar water)
Taste from the cup containing fresh water. Did the taste of thefresh water surprise you? How? Record your reaction.
Experiment 3:
Take about 15 index cards and a flashlight that is opaque on allsides (so that light shines only through the front) into a verydark room.
Place all 15 cards over the beam of light.
Slowly remove the cards one at a time until you can barely detectthe light, and then count the number of cards that remain over thelight.
After a few minutes, the light should begin to look brighter. Whenthis is the case, add cards and see if you can still see thelight.
Repeat this process of gradually adding cards over a 15-minuteperiod. Were you able to detect an increasingly dim light thelonger you spent in the dark? Record your reaction.
How many cards did it take to not see the light after time?
Experiment 4:
Fill 3 medium-sized bowls as follows:
Bowl 1 – with very hot (but not painfully hot) tap water
Bowl 2 – with very cold tap water
Bowl 3 – with a mixture of the very hot and very cold water.
Arrange them, so your right hand is in front of the cold water,your left hand is in front of the hot water, and the lukewarm wateris in the middle.
Submerse your hands into the water (right into cold, left into hot)for about 3 minutes
After 3 minutes, quickly transfer both hands to the lukewarm(middle) bowl. What did you sense? Record your reaction.
In all four experiments, you will experience adaption.
Task 2: Write a paper that describes adaption and how youexperienced it in your experiments. The paper should cover thefollowing.
Fully describe the process and results of the experiments that youchose.
What is sensory adaptation? Explain the concept of sensoryadaptation. Refer to your text for the definition of sensoryadaptation (this is not the general dictionary definition)
Explain how adaptation is evident in each of your experimentalresults.
Provide a comprehensive description of the sensory systems that areinvolved in the experiments that you performed. This descriptionshould include what happens from the receptors to the brain. Yourdiscussion should illustrate what was experienced in eachexperiment.
Discuss how adaptation is important from an evolutionaryperspective.
Be sure to document your references using APA format
