Chapter 3 Heritability

Based on my knowledge and understanding, "some trait is highly heritable" mean that some trait can be more attributable to the genetic factors rather than environment factors. For example, let's say that IQ is highly heritable, this statement says that the difference in intelligence can be more accounted to the genetics factors.

In the flute case, I think you should not stop practicing. Just because someone tells you that musical ability is heritable, does not mean that it is 100% affected by the genetic factors only. Even highly heritable traits like musical ability can be modified by the environment. In this case, the environment such as practicing can help you improve your musical ability.

Chapter 2 The "Cheating" Survey

I don't think we can justify the assumption that the sample represents all the married Canadian women since the survey only taken by the female readers of that particular magazine, we do not even know the amount of people that have taken the survey and they are more likely fell in same category. For example, most of the female readers of the magazine might be around 25 - 35 years old which clearly does not represent all married Canadian women. The result are more likely biased based on that. I personally think it is relevant in the sense that they are trying to get more users by funding this survey. It may sound unethical, but I think that might be the way to market the online dating service. In my opinion, the title should be "cheating survey based on the reader of this magazine".

Chapter 4 Brains Scans

Brain scans such as EEG, PET and fMRI did provide us with fabulous windows on the brain, but it does not necessarily mean that we can interpret the result as is. Each of the brain scans type have their own weaknesses. For example, EEG is not very precise because it reflects the activities of so many cells at once (115). In the case for this "doodling centre" I personally do not think that we can classify the area of the brain as "doodling centre". We cannot oversimplify the brain function by what it does process specifically. Since brain is really complex organ, interpreting brain scans is going to be super complicated. Since brain is structured by billions of neurons. First, let's say that the area that active is motor cortex. This motor cortex also have many other function rather than just doodling. For example, moving other parts of body. We have to take the other part of the brain into account. I believe there is some part of the brain that is functioni...

Chapter 5 Reactions to Alcohol

There is a lot to considers on how the qualities of the user might account to the reactions of alcohol to a person rather than the drug effects itself. People often assume that the effect of a drug like alcohol are always the same, but that is not necessarily the case. They also depend on a person's individual factor, experience with the drug, environmental setting and their mental set. Individual factors is how our physical conditions of our body reacts to the alcohol itself. For example, our body weight will determine on how much alcohol intake we can drink until we blackout.  Experience with the drug refers to the number of times a person has taken it. The effect of the drug will be different with someone who drink an alcohol drink for the first time and someone who drink it regularly. Some person who drink for the first time might feel "mellow out" while the other person who drink regularly might have different effect. Environmental setting is when, where and who...
