PICK UP A SLIP FROM THE FRONT End of the Year Calendar Review (1 Chapter to go!) Vocabulary Assignment Memory Activity Notes
3
VII. Cognition (8–10%) AP students in psychology should be able to do the following: Compare and contrast various cognitive processes: ▪ — effortful versus automatic processing; ▪ — deep versus shallow processing; ▪ — focused versus divided attention. Describe and differentiate psychological and physiological systems of memory (e.g., short-term memory, procedural memory). Outline the principles that underlie effective encoding, storage, and construction of memories. Describe strategies for memory improvement. Synthesize how biological, cognitive, and cultural factors converge to facilitate acquisition, development, and use of language. Identify problem-solving strategies as well as factors that influence their effectiveness. List the characteristics of creative thought and creative thinkers. Identify key contributors in cognitive psychology (e.g., Noam Chomsky, Hermann Ebbinghaus, Wolfgang Köhler, Elizabeth Loftus, George A. Miller).

How does information get into memory? How is information maintained in memory? How is information pulled back out of memory?
5
Figure 7.2 Three key processes in memory
6
The role of attention Focusing awareness Selective attention = selection of input Filtering: early or late? https://www.youtube.com/watch?v=fO7WcGsKhFU https://www.youtube.com/watch?v=fO7WcGsKhFU

Figure 7.3 Models of selective attention
8
Incoming information processed at different levels Deeper processing = longer lasting memory codes Encoding levels: Structural = shallow Phonemic = intermediate Semantic = deep
9
Figure 7.4 Levels-of-processing theory
10
Figure 7.5 Retention at three levels of processing
11
Elaboration = linking a stimulus to other information at the time of encoding Thinking of examples Visual Imagery = creation of visual images to represent words to be remembered Easier for concrete objects: Dual-coding theory Self-Referent Encoding Making information personally meaningful

Analogy: information storage in computers ~ information storage in human memory Information-processing theories Subdivide memory into 3 different stores ▪ Sensory, Short-term, Long-term
16
Figure 7.7 The Atkinson and Schiffrin model of memory storage
17
Brief preservation of information in original sensory form Auditory/Visual – approximately ¼ second George Sperling (1960) ▪ Classic experiment on visual sensory store ▪ Iconic memory and cued recall
18
Figure 7.8 Sperling’s (1960) study of sensory memory

Limited capacity – magical number 7 plus or minus 2 Chunking – grouping familiar stimuli for storage as a single unit Limited duration – about 20 seconds without rehearsal Rehearsal – the process of repetitively verbalizing or thinking about the information https://faculty.washington.edu/c hudler/stm0.html https://faculty.washington.edu/c hudler/stm0.html George Miller’s “The Magical Number 7-Plus or Minus 2”

STM not limited to phonemic encoding Loss of information not only due to decay Baddeley (1986) – 3 components of working memory Phonological rehearsal loop Visuospatial sketchpad Executive control system
23
Permanent storage? Flashbulb memories Recall through hypnosis Debate: are STM and LTM really different? Phonemic vs. Semantic encoding Decay vs. Interference based forgetting
