Cognition and Learning Flashcards
(123 cards)
Selective attention
attending to one thing while ignoring others
divided attention
paying attention to one thing more than another
Broadbent’s model
Filters out the message before incoming information is analyzed for meaning
Treisman’s attenuation model
Language and meaning can be used to separate messages. The analysis only goes as far as it takes until the message is identified.
Attenuation theory
message is split between what is attended and unattended. Then they pass through the attenuator, but the attended message emerges at full strength while unattended message comes through weaker. Message is analyzed by a dictionary unit and is then converted to memory. Broadbent goes though sensory memory and is then passed through a filter. and then through a detector unit before it is committed to memory.
late selection
most of the incoming information is processed by meaning before the message is selected
early selection
unattended information is filtered out right at the beginning of the flow and filtered using physical characteristics
stroop effect
name of the word interferes with the ability to name the ink color. Cannot avoid paying attention to the meanings of the words.
Attention
focusing on a specific features, objects, or locations or on certain thoughts or activities
Visual perception
the ability to interpret the surrounding environment by processing information that is in visible light
Covert attention
shifting attention from object to object without moving your eyes
overt attention
shifting eyes to change attention
topographic map
spatial map of visual stimuli on the visual cortex
inattention blindness
over looking something that is in plain sight
low-load task
a task that requires little processing capacity.
high load task
a task that uses a high amount or all of processing capacity, such as first learning to drive etc
Treisman’s feature integration theory (FIT)
Preattentive stage- 1st step in processing an image, objects are analyzed into separate features and exist independently
Focused attention stage- combines “free floating” feature to create the perception of the whole object
scene scheme
identifying objects that typically exist in a certain setting
change blindness
if shown two versions of a picture, differences between them are not immediately apparent
Binding
the process by which features such as color, form, motion, and location are combined to create our perception of a coherent object
Binding problem
the problem of explaining how an objects individual features become bound together.
Working memory on reading processing
A limited-capacity system for temporary storage and manipulation of information for complex tasks such as comprehension, learning and reasoning.
George miller’s contributions to short term memory
Digit span- number of digits a person can remember average cap 7 plus or minus 2.
Chunking- small units can be grouped into remembering large chunk
Response of Broadbent (1958)
filter model introduced a flow chart, this helped usher in the information processing approach to cognition.
