What was the effect of the intervention on the love group's mean ratings after one week in Experiment 2?

In Experiment 2, the intervention specifically aimed to enhance the feelings of love among participants. The mean ratings before the intervention were at a baseline of 1.7, and the significant increase to 4.2 after one week indicates a remarkable positive effect of the intervention on the participants' perceived levels of love. This substantial rise demonstrates that the methods used were effective in promoting these feelings, as evidenced by the mean rating substantially exceeding the starting point. The transition to 4.2 reflects a strong impact, suggesting that participants experienced a considerable enhancement in their emotional states regarding love due to the intervention. Such findings can be critical in psychological studies, as they suggest that interventions can effectively influence emotional experiences.
