Who Believes More in Love at First Sight?

Who believes more in love at first sight, men or women?

Method
The first part of the experiment will be a lab study where the participants will be shown a series of images of the opposite sex who are attractive. We will then measure their heart rate and hormone levels to see the differences from before the image and after. When all of the data is collected from each of the participants the results will then be complied in to quantitative data. The second part of the experiment will be a an anonymous questionnaire. The results collected from this will then be compiled and compared to the lab study results and averaged out as a whole to get the overall statistics.
There are many advantages in using these methods of research for example in the case of lab studies the investigator has control over all aspects and there is also access to specialised equipment and the experiment can be replicated. When using questionnaires the main advantages are the fact that they are cheap, quick and easy and can be easily replicated.
However there are also some disadvantages to using these methods the main one being behavioural changes such as evaluation apprehension and demand characteristics in the lab study and social desirability in the questionnaires. There Is also the problem of low ecological validity in the lab studies as the participants may act differently as they are not in there natural enviroment.
