Unit 5 Chapter 4 - PART 2 - The ear and auditory sensation

(Scroll down for the first part of this chapter including due-dates and the visual system)

The organization that gives out the Nobel Prize has a great website about the ear and how it works.

If you're having trouble understanding the accessory structures and the cochlea this site is for you.














Animations and interactives that explain the ear.

The Sumanas inc. video goes into great detail about the inner ear.
http://www.sumanasinc.com/webcontent/animations/content/soundtransduction.html
Another video on YouTube is great 3D animation that takes you into the ear as if you are a sound wave... it demonstrates the movements in the middle and inner ear with classical music... fantastic piece. The link is at http://youtu.be/PeTriGTENoc - since it's YouTube it may not work at school... 


Hearing Tests: 
You need over-the-ear headphones and a decent computer to use this (not medically accurate) hearing test, but it's interesting to check out even if you don't have the right set-up.  Keep your volume at a moderate level, and if you stop hearing the tone DO NOT increase the volume to try to hear it. 

This website has lots of different tone generators including this hearing test

This one:  http://youtu.be/h5l4Rt4Ol7M  is a YouTube video, so it may not work at school. 
Mr. Cantor who was born in 1964 can hear sounds below roughly 14,000 Hz. How about you? -- 
YouTube actually compresses  audio, so this may not be accurate. Try the link above for more accuracy.

Fantastic animations about the eye, visual processing in the retina and the pathways that visual information travels in the brain.


This beautiful hand painted animation is a great overview.   https://youtu.be/EskTnxBoPoI



Pay close attention to the "center-surround" aspects of retinal processing in this Web Animation below. The narrator's voice is a bit boring, but it's a great video that explains the whole "center-surround" opponent process thing. 
http://www.sumanasinc.com/webcontent/animations/content/receptivefields.html
This animation shows how the photoreceptors, bipolar and ganglion cells of the retina are organized in "center-surround" arrangements that allow "bottom up" processing of visual information to begin in the retina. 



If a picture is worth a thousand words, an animation is worth way more. This animation really shows the visual pathway very well. Pay attention to how visual information is split in the Optic Chiasm and how it routs through the LGN of the thalamus as well as other areas specifically related to eye movement and the "biological clock" which controls circadian rhythms.

This excellent animation really explains how the visual information from the left and right visual fields makes its way to the right and left occipital lobes via the LGN of the thalamus. 

Check out this amazingly comprehensive video that covers the visual system in about 10 minutes. It's on YouTube, so it may be hard to watch at school. Link: http://youtu.be/AuLR0kzfwBU


What do you see in the circle?

This site sells glasses that are supposed to correct for some color blindness. I don't know how well they work, but they do have a really nice color blindness test. http://enchroma.com/test/instructions/ 

Do you have "SuperVision? Are you a tetrachromat - a person with 4 
types of cones rather than 3? This website has a test for you. 



Ever wonder what those little blobs floating around your visual field are? They'r caused by shadows of little chunks of debris floating around in the vitreous fluid inside your eye-ball.  This video explains it all: https://www.youtube.com/watch?v=Y6e_m9iq-4Q

And Hank's Crash Course Psychology is always good...

Flash-Cards
1.     Key Term FlashcardsThere are 63 Key Terms highlighted in the textbook. Do at least 45. Do 5 to 7 per day and you’ll be fine.
2.      Pictures/diagrams are important to this unit!

3.     Don’t freak out. I know it’s a lot of flashcards. It will be worth memorizing and understanding the key terms. You will need to review the flashcards before quizzes and exams in class and as you study for the AP exam.
+++++++++++++++++++++++++++++++++++


This site has some very easy to read descriptions of parts of the brain. Use it to help you understand what's between your ears if our book gets too confusing.  http://brainmadesimple.com/index.html

Our friend Hank discusses the chemistry of our brain...



Try this EdPuzzle link which asks you some questions as the video plays to check to see if you are understanding important points. It was developed by AP Psych teacher Mr. Mcentar. 

And Hank discusses the overall structure of the brain... from phrenology to Phineas to the old brain and the new brain.



Here is the EdPuzzle link for this video... try it out! Remember, quizzing yourself and connecting new information to old is the best way to learn new content.

More specifics about neurons and the nervous system... Thanks HANK! 



And... Hank on the Action Potential... You need to know the basics of how action potentials work. This video goes into a bit more detail than you'll need for the AP exam, but it's super solid. 




And the Synapse... where lots of the action happens! Focus on the chemical synapses... the electrical synapses are more specialized and more abundant in embryonic development than in our fully developed nervous system (and the chemical synapse will show up on the AP exam.)

Welcome to AP Psych! - Memory Unit 1

Unit 1 Chapter 7 Memory
Key ideas from Memory Unit:
Encoding, episodic vs. semantic and procedural memory, explicit vs. implicit memory, maintenance and rehearsal strategies to improve memory, various models of how memory works such as PDP and Info Processing, understand the difference between sensory, short term, and long term memory, compare recency and primacy effects, understand what affects memory retrieval, understand the limits of eye-witness testimony, Herman Ebbinghauss , compare retroactive and proactive interference,  compare retrograde and anterograde amnesia,
*****Use mnemonics and distributed practice to learn all this stuff and know why you are remembering and forgetting.




Good overview of basic memory concepts.

A whole site dedicated to human memory... very helpful. It has this very complete concept map.
http://www.human-memory.net/types.html
Crash Course Psychology with our friend Hank!
How we make memories...  https://youtu.be/bSycdIx-C48 




Remembering and Forgetting 
  
Some fun memory games you can do online

Elizabeth Loftus's Ted Talk - The Fiction of Memory... the rape conviction of an innocent man... 


NOVA: How Memory Works


Article - What Science Says about Ferguson: Hacked memory.  We may all be working from different sets of "facts" about the same event.
http://www.forbes.com/sites/fayeflam/2014/12/01/what-science-says-about-the-ferguson-case-memory-can-be-hacked/

This is not specifically about memory, but about implicit associations we make about people.
https://implicit.harvard.edu/implicit/demo/ You can take some of the Implicit Association Tests to see what some of your implicit associations about people and groups are. I’m putting it with this unit as an example of implicit vs. explicit thought processes.

Story from National Public Radio (NPR) about H.M., the man who had the bilateral removal of his hippocampus (What is the plural of hippocampus?) and ended up with the nearly complete inability to form new memories. Find out why he had his hippocampus removed and learn about this amazing case study of anterograde amnesia. 
 http://www.npr.org/templates/story/story.php?storyId=7584970

And an article from Psychology Today about H.M.

This video clip was made based on 2000 slices that were made of H.M.'s brain after he died in 2008. 



The movie Memento was the first feature film by star director Christopher Nolan who went on to direct The Dark Night and Inception. It is a fictional film about a character who, like H.M.,  loses the ability to create any new memories, but still tries to solve a horrible crime.

It is rated R due to some very violent content and adult language. If that sort of film is acceptable to you and your parents, you can stream it on Netflix or rent it. It's definitely not appropriate for younger siblings.
