1
The ability to store and retrieve information over time.
MEMORY The ability to store and retrieve information over time.
2
Key Terms Cognition* The process of acquiring and using knowledge: thinking. Information Processing Theory * The mind is similar to a computer with input, processing, and output. Reconstructive Memory * Memory is stored in pieces, and later put back together using past & present information, emotions, beliefs, bias. Eyewitness Testimony
3
Stages of Memory * Sensory memory *
Brief storage of sensory information Iconic (visual) and Echoic (auditory) Short term memory (STM) * Small amounts of memory (5-9 bits) Less than 1 minute (20-30 sec) Working Memory * Memory processes used in STM Long Term Memory * Storage of information, schemas* Schemas = Pattern of knowledge to help organize information. Memory (video)
4
Stage Model of Memory Attention Encoding
5
Sensory Memory Test Watch this video and follow instructions:
Sensory to Short Term Memory: Attention For those who did not pay attention, what factors contributed to this failure? Watch: Door Video. What is happening? What real-world situations might occur when a failure of attention causes information be lost before it reaches short term memory? What might the consequences be?
6
Long Term Memory * A. Explicit (Declarative) Memory *
Knowledge or experiences that can be consciously remembered. 1. Episodic Memory * First hand experience (e.g. first date) 2. Semantic Memory * Facts and concepts (e.g. presidents) B. Implicit (Nondeclarative) Memory * Experience (procedural) e.g. riding a bike, using a keyboard, swimming
7
Measuring Long Term Memory *
Recall * Free recall – e.g. essay test (Discuss Thorndike’s theory) Cued Recall – e.g. fill in the blank questions (Thorndike proposed the law of _____). Recognition * Remembering previously seen information E.g. Multiple choice tests (Thorndike proposed the law of a. effect b. behavior c. consequences d. averages)
8
Techniques to Improve Memory
Maintenance Rehearsal * Repetition; not very effective Chunking * Chunking video Remembering sets or groups. Increases capacity. Elaborative encoding * Relate to another memory. Elaborative rehearsal * Study by finding more examples and using other methods, e.g. Organization
9
Mnemonic Devices * Memory aids, e.g. associations, rhymes, songs, images, Method of Loci (place; story-telling) Self-referencing * Apply the material to yourself. Overlearning * Keep studying Spacing * Distributed better than massed practice; don’t cram the night before test Forgetting Curve Video
10
Processing Memory Encoding *
Process of putting information into memory Storage * Physical memory connections in the brain Retrieval * Finding & taking information out of memory
11
Which memory process failed: encoding, storage or retrieval?
Which is the real penny? Which memory process failed: encoding, storage or retrieval?
12
(declarative) (nondeclarative)
13
Causes of Forgetting Decay Theory * Applies to STM, not LTM
Encoding failure * Information not stored properly; can’t find it Retrieval Failure * Inability to bring information into working memory Tip of the tongue phenomenon Amnesia * Biological cause , e.g. disease, head injury
14
Forgetting, cont. Motivated Forgetting * Interference *
Inability to encode or retrieve memories due to anxiety. Biological theory v. Freud’s theory Interference * Retroactive Interference – new learning impairs older memory Proactive Interference – Previous learning interferes with new memory.
