1. Can I get a “what? WHAT?” Memory

2. What comes to mind when I say the word “YELLOW?” What did you do on your 5 th birthday? Describe the events that occurred the last time you went to a restaurant. Who is the character in the next photo?

4. Three Basic Processes

5. ENCODING: This is the process in which a stimulus (word, object, idea…) in translated into a mental representation and can be stored in the memory. STORAGE: The changes in the neural system that allows retention of information. Moving encoded information to a memory store. RETRIEVAL: The process of recovering information from the memory store. This depends on how the information was encoded and stored.

6. Information-processing theories – Atkinson & Shiffrin (1977) Subdivide memory into 3 different stores Sensory, Short-term, Long-term

7. SENSORY: Brief preservation of information in original sensory form (iconic, echoic, tactile, taste, olfaction) ICONIC: Visual sensory store for a brief period of time (250 milliseconds or less... animation). Large storage capacity that we are generally not aware of. For information to have meaning and be retained beyond sensory memory, we must encode it is something recognizable and more durable.

8. Short-Term / Working Memory Some argue information is converted into acoustic, verbal code. Others argue that it is simple image-like. Others that it is an abstract representation, neither verbal or imaginable. STM: information we are currently thinking about or thought about within 30-60 seconds. – Maintain current information like “rehearsal” – Mental Workbench where we can perform operations (division) Capacity is limited Can only hold information briefly Let’s test our memory!

9. Short-Term Memory as “Working Memory” STM not limited to phonemic encoding Loss of information not only due to decay Baddeley (2001) – 4 components of working memory – Phonological rehearsal loop – Visuospatial sketchpad – Executive control system – Episodic buffer

16. LTM Rehearsal: repeat things over and over Elaboration: connecting new information with information already stored – Semantic Memory: list these words Horse, desk, shirt, chair, cat, jeans, dog, couch, cow, socks, table, jacket, hat, sheep Episodic Memory: One of my happiest days Procedural Memory: Tie someone's shoe Flash bulb memories: “9/11”

18. What will you remember from this next slide?

20. Write down all the objects that you remember just seeing.

21. Who’s up for some Simon?

22. List 1: read, pages, letters, school, study, reading, stories, sheets, cover, pen, pencil, magazine, paper, words List 2: house, pencil, apple, shoe, book, flag, rock, train, ocean, hill, music, water, glass, school What word (s) were also in List 1? Only pencil and school were on list 1 False Memories

23. List 1: sheets, pillow, mattress, blanket, comfortable, room, dream, lay, chair, rest, tired, night, dark, time List 2: door, tree, eye, song, pillow, juice, orange, radio, rain, car, sleep, cat, dream, eat What items were on list 1? Only pillow and dream were on list 1. Why the false memories? Because we semantically want to group words, the activation of these concepts (the word “sleep”) spreads to other related concepts (doze, nap, tired).

26. Would you be a good eyewitness?

27. Eyewitness Testimony If you had watched two vehicles involved in a car accident, how would the wording of the following questions influence your recall. – How fast was the car going when it smashed into the other car? – How fast was the car going when it collided into the other car? – How fast was the car going when it hit the other car? – How fast was the car going when it bumped the other car? – How fast was the car going when it contacted the other car? Leading Questions: estimates based on the suggestion of the verb Altered Memory Representation: actual change in the memory of the severity of the accident Which questions would lead you to recall broken glass a week later?

30. Improve your memory! Mnemonics: cues that enhance memory by linking organizational sets of “411” to memory elements that already exist. – Imagery (Paivio’s research on “dual coding”) verbal + pictorial – Acrostics – Songs & Rhymes – Method of Loci: use of locations to remember items and associate to- be-remembered “411” with a specific location. Snack vs Binge Learning Over learning Limiting interference

31. How is Knowledge Represented and Organized in Memory? Clustering and Conceptual Hierarchies – Schemas and Scripts – Shank & Abelson (1977) Semantic Networks – Collins & Loftus (1975) – Connectionist Networks and PDP Models – McClelland and colleagues - pattern of activity – neuron based model
