Question 5

Use the following to answer questions
Scenario I
Scenario I is based on fabricated data inspired by the following study:
Gueguen, N. (2015). High heels increase women's attractiveness. Archives of Sexual Behavior, 44(8), 2227-2235.
Do high heels make women attractive?
The purpose of this study was to determine whether the height of the heels of a woman's shoe affected their perceived attractiveness. To that end, the researchers conducted four studies using female confederates who wore shoes with a heel height of 0, 5 or 9 cm. In the first study, the women posed as laboratory assistants who administered a survey on gender equality to male volunteers. In the second study, the women posed as laboratory assistants who administered a survey on food habits to male volunteers. The third study examined how likely men in study 1 and study 2 were likely to help women based on their shoe type. Specifically, female confederates posing as laboratory assistants dropped a latex glove while the men waited to participate in the study 1 and study 2 surveys. The confederates recorded whether men picked up the dropped glove. In the fourth study, a female confederate sat alone at a table in the university library and the researchers measured the amount of time it took the men to approach her. The results of the study revealed that men were affected by the confederate's shoe heel height; the higher the heel, the more likely men were to help the confederate. Almost all of the men picked up the confederate's glove in the high-heel condition compared with the mid-heel and flat condition. The time-to-approach dropped in half when the confederate was wearing high heels rather than no heels.
-(Scenario I) Why might the researchers have had three research assistants independently but simultaneously watch the confederate in the library described in study 4 of Scenario I?

Accepted Answer

Having three research assistants independently but simultaneously watch the confederate in the library helps to establish inter-observer reliability. This means that multiple observers are able to produce consistent results and increase the validity of the study. Blinding and having a minimum of three observers may also be best practices, but they are not the main reason for having multiple observers in this study.

Question 6

Use the following to answer questions

The time-to-approach dropped in half when the confederate was wearing high heels rather than no heels.
-(Scenario I) Which of the four studies described in Scenario I has the greatest degree of ecological validity?

Accepted Answer

The fourth study, where a confederate sat alone in the university library, has the greatest degree of ecological validity as it simulates a real-life scenario where men might approach women they find attractive. The other studies involve the confederates posing as laboratory assistants and administering surveys, which may not reflect real-life situations.
