Researchers were interested in how social situations can influence stress-induced eating. They grouped participants according to self-reported stress-induced eating habits: consistently eating more (hyperphagic) or eating less (hyperphagic) when stressed. Each participant was then exposed to one of three social situations: 

(1) a social inclusion condition, where subjects were told that a confederate partner had approved of a video they had made answering some questions and was looking forward to meeting them,

(2) a neutral condition, where they were told their partners could not meet them because their partners had to cancel their participation 

(3) a social exclusion condition, where they were told that their partner had decided not to meet them after viewing their video. Subjects were then given an ice cream taste test and the amount of ice cream consumed was measured. 

Question: In this particular scenario, how many hypotheses are there?
