  6. Procedure of Study 1 – Pour and Consume PRE-EXPERIMENTAL MEASURE – How thirsty are you? Pour + Consume Rate Mood + Arousal Visible Neutral (400 msec) Gender Identification Task Subliminal Emotion x 8 (16 ms) Happy, Neutral, Angry

  7. Amount of drink poured and consumed by thirsty participants as a function of subliminal expression

  8. Rating of mood as a function of subliminal expression.

  9. Procedure of Study 2 – Sip & Rate • Same priming procedure • Small, fixed amount to drink –”take a sip” • Extensive mood measure

  10. Ratings of wanting for more drink among thirsty participants as a function of subliminal expression.

  11. Willingness to pay for a can of the drink among thirsty participants as function of subliminal expression.

  12. Summary of affective priming studies • Subliminal affective stimuli can influence actual behavior (including consumption) and judgments (including monetary assessments). AFFECTIVE REACTIONS CAN HAVE UNCONSCIOUS CAUSES • Subliminal affective stimuli can work without awareness of affective change. AFFECTIVE REACTIONS CAN BE UNCONSCIOUS • Affective influence does not require inferences from conscious experience. AFFECTIVE REACTIONS CHANGE PREFERENCES DIRECTLY
