  1. Subliminal Perception: Unconscious Cognition Unconscious Perception Selective Attention I 5S Subliminal Perception: Unconscious Cognition

  2. Objectives: Be able to Discuss the differences in process between subjective and objective thresholds. Define subliminal perception. Define subliminal activation. I 5S Subliminal Perception: Unconscious Cognition

  3. Examples of Unconscious Cognition • Highly practiced “automatic” acts - driving a car • Without Mental Effort • Without ability to remember details of what happened • Monitoring of background conversations I 5S Subliminal Perception: Unconscious Cognition

  4. Two Senses of Unconscious • Outside of Attention • Lack or Failure of Introspection I 5S Subliminal Perception: Unconscious Cognition

  5. Outside of Attention • Consciousness as the selective aspect of Attention • Limits of cognitive analysis of registered, but unattended stimuli? • Memory residue? I 5S Subliminal Perception: Unconscious Cognition

  6. Lack or Failure of Introspection • Inability to report an experience validly • Verbally unreportable experiences I 5S Subliminal Perception: Unconscious Cognition

  7. Levels of Analysis • How smart is unconscious cognition? I 5S Subliminal Perception: Unconscious Cognition

  8. Subliminal Activation • Subliminal Semantic Activation • Objective and Subjective Thresholds I 5S Subliminal Perception: Unconscious Cognition

  9. Subliminal Semantic Activation • Present a word subliminally • Affects recognition of other words presented above threshold • Affects spelling of other words presented above threshold I 5S Subliminal Perception: Unconscious Cognition

  10. Measuring Thresholds • Objective thresholds • Subjective thresholds I 5S Subliminal Perception: Unconscious Cognition

  11. Objective Thresholds • present a word • present a number of choices • Participant must choose one of the choices • Forced Choice - like multiple choice test • None of the Above is not allowed • Yields a low threshold I 5S Subliminal Perception: Unconscious Cognition

  12. Subjective Thresholds • Present a word • present choices or not • Allow “I don’t know “ responses • Yields a higher threshold I 5S Subliminal Perception: Unconscious Cognition

  13. Threshold for Subliminal Semantic Activation • Between Objective and Subjective Thresholds • Semantic activation also works very well above threshold • Is there Subliminal Semantic Activation of Multi-word sequences?? • How could you know? I 5S Subliminal Perception: Unconscious Cognition

  14. Discussion Question 11 • Compare and contrast subjective and objective thresholds. Explain how they are important in subliminal perception. I 5S Subliminal Perception: Unconscious Cognition

  15. Discussion Question 12 • What does Greenwald mean by subliminal activation and what does he say are the necessary conditions for subliminal activation to occur? Discuss. I 5S Subliminal Perception: Unconscious Cognition

  16. Objectives: Be able to Discuss the differences in process between subjective and objective thresholds. Define subliminal perception. Define subliminal activation. I 5S Subliminal Perception: Unconscious Cognition
