1 HOT ROC: Comparing Subjective Information Form groups of four Form groups of four For each of the following list, rate as a percentage the amount that environment and heredity influence the trait For each of the following list, rate as a percentage the amount that environment and heredity influence the trait (ex. Intelligence: environment 60%, heredity 40%) (ex. Intelligence: environment 60%, heredity 40%) 1. Body build6. Handedness 1. Body build6. Handedness 2. Intelligence7. Height 2. Intelligence7.

3 Sensation & Perception

4 Sensation Definition What occurs when a stimulus activates a receptor What occurs when a stimulus activates a receptor How many senses are there? How many senses are there? 5 Senses 5 Senses Sight, Hearing, Smell, Taste & Touch Sight, Hearing, Smell, Taste & Touch

5 Absolute Thresholds Weakest detectable sensation Weakest detectable sensation Examples (do not write down) Examples (do not write down) Sight- Seeing a candle flame 30 miles away on a clear night Sight- Seeing a candle flame 30 miles away on a clear night Hearing- Hearing a watch ticking 20 feet away Hearing- Hearing a watch ticking 20 feet away Taste- 1 teaspoon of sugar dissolved in 2 gallons H2O Taste- 1 teaspoon of sugar dissolved in 2 gallons H2O Smell- 1 drop of perfume in a 3 room house Smell- 1 drop of perfume in a 3 room house Touch- Feeling a bees wing fall 1 cm onto your cheek Touch- Feeling a bees wing fall 1 cm onto your cheek

6 Perception Definition Organizing sensory info. into meaningful experiences Organizing sensory info. into meaningful experiences Brain tries to make sense of large amount of stimuli Brain tries to make sense of large amount of stimuli Creates wholes out of bits of info. (Gestalt) Creates wholes out of bits of info. (Gestalt)

7 Perceptual Set Past experiences and perceptions create a framework through which you view the world Past experiences and perceptions create a framework through which you view the world Ex I perceive all old people as kind b/c my grandma is kind. Ex I perceive all old people as kind b/c my grandma is kind.

9 Simplicity (Reification) We see the simplest shape possible We see the simplest shape possible

10

11 Proximity When objects are close together, we tend to perceive them as groups When objects are close together, we tend to perceive them as groups

12

13 Similarity When similar and dissimilar objects are mingled, we see similar objects as groups When similar and dissimilar objects are mingled, we see similar objects as groups

14

15 Closure When we see a familiar pattern or shape w/missing parts, we fill in the gaps When we see a familiar pattern or shape w/missing parts, we fill in the gaps

16

17 Continuity We tend to see continuous patterns, not disrupted ones We tend to see continuous patterns, not disrupted ones

21 Invariance Simple geometrical objects are recognized independent of rotation, translation, and scale; as well as several other variations such as elastic deformations, different lighting, and different component features.

22 Other Interesting Perception Techniques

23 Count the number of Fs FEATURE FILMS ARE THE RE- SULT OF YEARS OF SCIENTI- FIC STUDY COMBINED WITH THE EXPERIENCE OF YEARS

24 FEATURE FILMS ARE THE RE- SULT OF YEARS OF SCIENTI- FIC STUDY COMBINED WITH THE EXPERIENCE OF YEARS Answer: 6 Most people see 3, but dont notice the fs on OF. It appears that we process those fs as vs.

28 Size Constancy

29 The Blakemore-Sutton Effect First, judge whether these two grating have the same size bars.

30 The Blakemore-Sutton Effect Look back and forth across the central bar.? Count to about 45 second and then press the mouse.

31 The Blakemore-Sutton Effect Do the gratings still have the same bar size?
