BIOL 101 Individual Assignment 2 Answers Liberty University Attention deficit disorder (ADD) is a syndrome in which a person has difficulty focusing sustained attention on a task for a significant amount of time. In some cases this is accompanied by hyperactivity as well. It is currently being diagnosed at an all-time high. Between 1989 and 1996, youth visits for ADD increased 90%, from 1.9% of total physician visits to 3.6%. Now, a psychiatrist named Dr. Edward Hallowell is making a new distinction. He has described a similar set of characteristics in a large number of patients that he terms Attention Deficit Trait (ADT). It looks a lot like ADD in its day-to-day manifestation, but unlike ADD, ADT symptoms lessen when the sufferer goes on vacation or into a decreased sensory input setting for an extended time period (on the order of days or weeks). In such a long-term placid situation, the ADD sufferer’s problems continue unabated. Imagine that you have the general set of symptoms described above. But which of the two syndromes are causing your symptoms: the disorder (ADD) or the trait (ADT)? Approach your problem using scientific methodology—developing a question, a hypothesis, an experiment, and a control for the experiment. The initial question and the experiment that will be performed on you are provided. Your job is to state the hypothesis and to design the most important and most basic control for this experiment. Your Question: What’s my problem? Is it ADD or ADT?  Your Hypothesis: State your hypothesis based directly on the above question.  Your Control for this Experiment: You get a numerical result for the number of definitions you memorized. What does that number mean? Nothing—unless you have a control for your experiment. What is the most obvious control for this experiment? Your Experiment: Keeping your same diet, sleep habits, and basic activity level, you will be sent on a two-week vacation to the Bahama Islands. You will be given only a beach to walk on and your favorite friend to talk to, following which you will be asked to read and memorize 10 sequential definitions from a standard dictionary in 30 minutes. Major Hint: The study guide for Quiz 1 indicates where this topic is covered in your text. The two figures in that section give you valuable examples. Remember, the initial question and experiment are provided here. Be careful to provide what the assignment is asking for. Your assignment:  Write out a testable hypothesis in a brief sentence. Derive it from the question asked above. (Be certain that the experiment addresses it!)  In a second sentence, describe a basic, critical control situation (additional experiment?) that will give validity to the experiment described above. Number your sentences with “1” and “2” and do not use paragraph form. The sentences must not be submitted as an attached document, but entered into the text box provided.

What’s my problem? Is it ADD or ADT?
Hypothesis
The syndrome that I am currently experiencing is not ADD but ADT. I say that because
my symptoms are lessened when I go into a decreased sensory input setting for a week or two.
When I am in a relaxed setting I can remember far more than when I am going about my day at a
very fast pace.
Controlled Experiment #1:
For my first experiment, I monitored myself with the same diet, same sleeping habits and
kept the basic activity level for what is a normal everyday life for me. Before my vacation my
sister asked me to memorize 10 sequential definitions from a standard dictionary in 30 minutes.
My results surprised me as I was only able to recall 5 of the 10 definitions.
Results for Controlled Experiment #1: 5 out of 10 definitions recalled
Controlled Experiment #2:
For the second experiment, I went on vacation to the Bahamas Islands to relax; however,
I kept the same diet, the same sleeping habits and basically the same activity level. My sister and
I went for a walk on the beach and she asked me to memorize 10 sequential definitions from a
standard dictionary. In a relaxed environment, I was able to recall 8 out of the 10. Much better
than the first experiment.
Results for Controlled Experiment #2: 8 out of 10 definitions recalled
