Journal #___ Identify your five senses. What information do your senses provide your brain? What does your brain do with this information? What is perception and how can it impact your senses?

Sensation & Perception

Journal – Brain DUMP Write down EVERYTHING you can remember about the five senses. You can write paragraph form OR make a giant list. Write down EVERYTHING that comes to mind.

Sensation the stimulation of sensory receptors and the transmission of sensory information to the central nervous system ( the brain and spinal cord ) Stimulation of senses is automatic!!

Perception The psychological process through which we interpret sensory information!! Perception reflects knowledge, past experience and personal interests!!

Our PERCEPTION (what we THINK) affects our SENSATION (what we SEE, HEAR, SMELL, TASTE, AND FEEL)

Brain Games: Watch This

SENSATION

Absolute threshold The weakest amount of a stimulus that can be sensed… includes vision, hearing, smell, taste and touch. Thresholds differ from person to person.

Difference threshold The minimum amount of difference that can be detected between two stimuli. Ex: the difference between shades of colors BLUE Thresholds differ from person to person.

Signal-detection theory A method of distinguishing sensory stimuli that takes into account not only their strengths but also such elements as your setting, your physical state, your mood and attitudes. We focus on whatever is important!

Sensory Adaptation The process by which we become more sensitive to weak stimuli and less sensitive to unchanging stimuli Ex: city dwellers adapt to the sound of traffic

GROUPS OF THREE!! NOT one… NOT two… NOT four or even five…but THREE!!!

Group member Assignments The Human Eye – PG. 81 – 85 The Human Ear – PG. 85 – 88 Smell, Taste & Touch – PG. 88 – 92 Research is done as a group. EACH PERSON must turn in a booklet

Individual TASK Create an flip booklet on the five senses Each Booklet should include… –An illustration of the sense (if applicable) –A brief description of HOW the sense works –Use of all vocabulary terms WITH definitions in paragraph form (COMPLETE SENTENCES!!) Use your group members notes! Overall your booklet should be an informative handout of the details of how your assigned sense works! (these are your NOTES)

Terms to focus on… amplitude after image bitter blind spot cochlea conductive cones eardrum ear eye frequency hand kinesthesis lens mouth nose olfactory nerve retina rods pain photoreceptors pitch pupil salty sensorineural sour sweet taste buds vestibular visual acuity

What happens when are deprived of our senses?

PERCEPTION

Shape Constancy allows us to perceive a shape as staying the same even though the angle from which we view it appears to distort the object

Size Constancy our ability to see objects as maintaining the same size no matter how far away the object is

ability to recognize that color remains the same regardless of how it looks under different levels of light. Ex: A deep blue shirt you wore to the beach suddenly looks black when you walk indoors. Brightness Constancy

Figure Ground Perceptio n Our ability to perceive figures against a backgrou nd.

So, what is misperception? Misperception is to perceive incorrectly or misunderstand.

Misperception Selective thinking one selects to “see” favorable evidence while ignoring unfavorable evidence

Misperception Confirmation bias one tends to look for what confirms one's beliefs, and to ignore what contradicts one's beliefs

Misperception Self-deception misleading ourselves to accept as true what is false (Self-deception, a way we justify false beliefs to ourselves. “He wouldn’t cheat on me”)

Journal #14 Part 2 Define the phenomenon synesthesia. Use at least THREE examples from the film. Do you think synesthesia is real? Why or why not? Does everyone use synesthesia? Explain your answer using examples from the video.

Extrasensory Perception ( ESP ) ESP or extrasensory perception is perception occurring independently of sight, hearing, or other sensory processes. People who have extrasensory perception are said to be PSYCHIC.

Extrasensory Perception ( ESP ) Clairvoyance - obtaining information about events in a distant location. An example of this would be feeling like a relative was just in car wreck and it turned out to be true.

Extrasensory Perception ( ESP ) Precognition - a vision about an event before it occurs. Telepathy - mind-to-mind communication or the awareness of another person's thoughts. Telekinesis - is the ability to move objects using only mental influence.

Are YOU telepathic? EXAMPLE: Copy below onto your own sheet of paper. Names _________________ ________________ _________________
