Multifactorial designs: experiments that vary two or more independent variables. Adding a new level in research design is different than adding another independent variable. Mood induction and cognitive tests by rowe, hirsh and anderson (2007: 2 independent variables: mood induction and cognitive exercises, 2 levels for mood induction: happy and sad. 2 levels for cognitive exercises: verbal and visual: 4 groups of participants required: happy and verbal, happy and visual, Sad and verbal, sad and visual: for within-subjects: all participants would have to go through all 4 situations. More realistic, more economical with efficient design to evaluate separate and joint examples. Results will show how the independent variables interact. Perceived gaze direction and the processing of facial displays (reginald b. Adams and robert e. kleck: according to their theory, eye-gaze direction and facial expressions can each be understood in terms of approach-avoidance motivation (approach: confrontation or fight , avoidance: inhibition or flight )
