Sensations

Vision: A candle at 30 miles on a clear, dark night.

Hearing: The tick of a watch 20 feet away in a quiet room

Smell: One drop of perfume diffused throughout A three-room apartment

Touch: A bee’s wing falling on the cheek from 1 centimeter above

Taste: 1 teaspoon of sugar in 2 gallons of water

Subliminal Perception: Stimuli just below level of conscious awareness

“Below the Threshold”

Habituation: Brain stops attending to constant unchanging stimuli (cognitive)

• “tune-out” non-essential stimuli and focus on the things that really demand attention

Sensory Adaptation: Occurs when sensory receptors change their sensitivity to the stimulus (biological)

Perception: method by which sensations are organized and interpreted

Perceptual Expectancy: The tendency to perceive things a certain way because previous experiences or expectation influence those perceptions

• We tend perceive what we expect to perceive

• We usually think that we observe reality but the reality we observe or expeience is influenced by what we think we’re going to observe and experience, Kind of like a placebo effect
