Study unit 4.1 Human Memory Flashcards
Attention
Focusing awareness on a narrowed range of stimuli or events.
Structural encoding
Shallow processing. Emphasis is on the physical structure of the stimulus. Registers how words are printed or their length.
Phonemic encoding
Intermediate processing. Emphasis is on what a word sounds like. Naming or saying the words.
Semantic encoding
Deep processing. Emphasis is on the meaning of verbal input. Thinking about the objects and actions the words present.
Levels-of-processing theory
Proposes that deeper levels of processing result in longer-lasting memory codes.
Elaboration
Semantic encoding enhanced through the linking of a stimulus to other information at the time of encoding.
Visual imagery
The creation of visual images to represent words to be remembered, with concrete objects being easier to remember than abstract objects.
Dual-coding theory (Allan Paivio)
Memory is enhanced by forming both semantic and visual codes since either can lead to recall.
Motivation to remember
When high at the time of encoding, people are more likely to exert extra effort to attend to and organize information in ways that facilitate future recall, because the information is perceived to be important.
Sensory memory
Preserves information in its original sensory form for a brief time, usually only a fraction of a second. It allows the sensation of a visual pattern, sound or touch to linger for a brief moment after the sensory stimulation is over. (afterimage)
Short-term memory
A limited-capacity store that can maintain unrehearsed information for up to 20 seconds, but can be held longer through rehearsal.
Chunks
A group of familiar stimuli stored as a single unit, and increasing the capacity of short-term memory.
Working memory (Alan Baddeley)
A modular system for temporary storage and manipulation of information.
Phonological loop (WM component)
When using recitation to temporarily hold onto a phone number. Evolved to foster the acquisition of langauge.
Visuospatial sketchpad (WM component)
Temporarily hold and manipulate visual images. Mentally rearanging furniture.
Central executive system (WM component)
Controls the deployment of attention, switching the focus of attention and dividing attention, as needed.
Episodic buffer (WM component)
A temporary, limited capacity store that allows the various components of WM to integreate information and that serves as an interface between WM and long-term memory.
