Option Bis correct.A psychologist was interested in gauging the success of a mood manipulation during one of her experiments. She had three groups of participants who underwent different types of mood induction: disgust mood induction, negative mood induction and positive mood induction. After the mood induction, participants were asked to endorse nine statements relating to their mood (on a 5-point Likert scale from 1 = disagree to 5 = agree): (1) When you’re smiling the whole world smiles with you, (2) I love the pretty flowers, (3) I could never touch a dead body, (4) I would never eat catfood, (5) If someone served me monkey brain soup I would vomit, (6) I feel fed up, (7) Bodily fluids are nasty, (8) I could not drink from a glass that I’d used to catch a spider,(9) I am a worthless piece of scum. What analysis should be done to see if the mood inductions had an effect on responses to these nine items?
