Final answer:
Drachman found that giving compliments before asking for a favor increased compliance, while a mixture of positive and negative comments or only negative comments decreased compliance.
Step-by-step explanation:
Drachman's study involved confederates asking for favors after giving compliments, a mixture of positive and negative comments, and only negative comments. The major findings of the study were that when confederates gave compliments before asking for a favor, participants were more likely to agree to the favor. However, when confederates used a mixture of positive and negative comments or only negative comments, participants were less likely to comply with the favor request. This suggests that positive comments can influence people to be more willing to help, while negative comments can decrease the likelihood of compliance.
