In Laney's second experiment, what was the main dependent variable?

In Laney's second experiment, the main dependent variable focused on the participants' responses to food pictures. This aspect of the study examined how the manipulation of the independent variable, which involved suggesting a false memory of enjoying asparagus, impacted how participants reacted to images of food, particularly their evaluation of asparagus. By measuring the changes in attitudes and preferences toward food, researchers could assess the effectiveness of the false memory manipulation. The responses to food pictures helped determine whether the false memory affected the participants' interests and feelings towards specific foods, thus serving as a crucial indicator of the experiment's outcomes.

The other options involve factors that did not directly assess the influence of the false memory in the context of the experiment's design. Feedback from social interactions, the number of photographs remembered, and the level of interest in cooking do not specifically relate to how the participants perceived and reacted to food imagery, which was the focal point of the study.
