objectives be able to
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

examples of unconscious cognition
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

two senses of unconscious
Two Senses of Unconscious
  • Outside of Attention
  • Lack or Failure of Introspection

I 5S Subliminal Perception: Unconscious Cognition

outside of attention
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

lack or failure of introspection
Lack or Failure of Introspection
  • Inability to report an experience validly
  • Verbally unreportable experiences

I 5S Subliminal Perception: Unconscious Cognition

levels of analysis
Levels of Analysis
  • How smart is unconscious cognition?

I 5S Subliminal Perception: Unconscious Cognition

subliminal activation
Subliminal Activation
  • Subliminal Semantic Activation
  • Objective and Subjective Thresholds

I 5S Subliminal Perception: Unconscious Cognition

subliminal semantic activation
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

measuring thresholds
Measuring Thresholds
  • Objective thresholds
  • Subjective thresholds

I 5S Subliminal Perception: Unconscious Cognition

objective thresholds
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

subjective thresholds
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

threshold for subliminal semantic activation
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?

Discussion Question 11
  • Compare and contrast subjective and objective thresholds. Explain how they are important in subliminal perception.
