Do Now: Write down the question below and your response The basic experience of stimulation of the body’s senses is called Sensation Perception Cognition Adaptation Conduction Homework Benchmark exam November 17/18 Sensation/Perception and States of Consciousness exam will be on Friday, December 4th

2 Perceptual Interpretation
Aim: How does perception impact the way we experience the world? Perceptual Interpretation Perceptual Adaptation (vision) ability to adjust to an artificially displaced visual field prism glasses demonstration

3 Psychophysics and Transduction
Aim: How does perception impact the way we experience the world? Psychophysics and Transduction Psychophysics: the study of how physical energy relates to our psychological experience Transduction: conversion of one form of energy into another Information goes from the senses to the thalamus, then to the various areas in the brain.

4 Hearing Threshold Partner Activity
Aim: How does perception impact the way we experience the world? Absolute Threshold Hearing Threshold Partner Activity the minimum stimulation needed to detect a particular stimulus 50 percent of the time A single candle flame 30 miles away A drop of perfume in a six-room apartment a ticking of a watch from 20 feet away The pressure of a wing of a bee falling on our cheek

5 Difference Threshold (Just Notable Difference)
Aim: How does perception impact the way we experience the world? Difference Threshold (Just Notable Difference) the minimum difference a person can detect between any two stimuli half the time Weber’s Law: difference thresholds differ by a constant percentage rather than amount **exact proportion varies by stimulus: weight must differ by 2%; light intensity by 8%

6 Signal Detection Theory
Aim: How does perception impact the way we experience the world? Signal Detection Theory predicts when we will detect weak stimuli amid background noise Things like motivation, experience, expectations, or physical state can effect what we sense A mom might sleep through a thunderstorm, but if one of her sons even whimpers, she is up!!!

7 Aim: How does perception impact the way we experience the world?
Sensory Adaptation Aim: How does perception impact the way we experience the world? diminished sensitivity as a consequence of constant stimulation Purpose is to help us focus on changes in our environment Water is cold at first but then you get used to it! Hear the “buzz” of a powered TV at first, but then goes away Why doesn’t our vision go away?? Do you feel your underwear all day?

8 Aim: How does perception impact the way we experience the world?
Subliminal Messages Stimuli below our absolute threshold We unconsciously sense it Read the article titled “How Stores Get You to Buy More…Without You Realizing It” Annotate the article Write a reflection that states how stores get us to do this
