What do you think influences our behavior more: nature, nurture, or a combination of both? How has technology affected the way we nurture our family and friends? Explain your answer.
Weegy: Many aspects of human characteristics (such as height and eye color) are largely genetically determined. [ Psychology researchers, however, tend to be interested in dimensions that are relatively less determined by genetics—traits that subject more to environmental influences, such as how a person feels, acts, and thinks. Given that the degree of genetic determination appears to vary from one dimension to another (e.g., spatial skills versus language acquisition), how can one determine the relative influences of heredity and environment for various human characteristics, and how can one understand the complex relationship between them?

What are some of the drawbacks to using the Internet for research and how can you overcome these?
Weegy: Some subjects may try to participant in the same study more than once To overcome this problem, you can ask for the email addresses of each participant, [ and then look for duplicates. Since nowadays its easy for people to create multiple email addresses, you can also ask for name and/or address of each subject. Sometimes researchers will have a "lottery" as incentive to participate (e.g., $100 lottery prize for each 400 participants), so asking for name/address is necessary to award the lottery check. You can also collect the IP address of each participant and look for duplicates. One issue here is that sometimes DSL providers give the same IP address to multiple people. Some subjects may drop out of the study before finishing In traditional laboratory-based research its unusual for a subject to walk out of a study, but online a subject can get distracted or simply lose interest and end the study. Sometimes researchers will have a "lottery" as incentive to have the subject participate in the study, but with any type of monetary incentive IRB's typically require a statement in the consent form saying something to the effect of "you may discontinue participation at any time without any consequences or losing your entry in the lottery." Since a certain number of online subjects wont finish the study, you can overcollect the number of subjects you think you need to offset the number of subjects who dont finish the study, usually around 10-20%. Some subjects may stop the study and then continue minutes/hours later The problem here is that some studies involve manipulations which may lose power if there is a time lag between the manipulation and measures in the study. ] (More)

One advantage of online studies is that you can record how long the subject is taking part in the study, so you can identify the average length of time of your study, and also identify those subjects who take an extrordinary long amount of time to finish the study. Some subjects may rush through ... (More)
