Chapter 3 3.4 Flashcards
Bottom-up processing - words letters (kids)
Aspects of recognition that depend first on information about stimuli that come up to the brain from the sensory systems.
Top-down processing - words (adults)
Aspects of recognition guided by higher-level cognitive processes and by psychological factors such as expectations.
Network processing
Send signals along a network that connects to your visual and motor cortices in your brain that then send signals to the neurons connected to your arm, hand, finger muscles so you can lift your hand.
Superiority effects - object & word
The phenomenon where people remember pictures better than they remember the corresponding words.
PDP - connectionist models
suggest that knowledge is distributed rather than being localized and that it is retrieved through spreading activation among connections.
Culture and experience - 2D pictures (hunting)
Focuses on the ways in which cultural processes shape cognitive, motivation, emotion, and behavior and the conditions that lead to different patterns of functioning across contexts.
Perception and development
How children start taking in, interpreting, and understanding sensory input.
Habituation Vs. Dishabituation
Habituation involves the diminished response to a frequency repeated stimulus.
Dishabituation is the fast recovery of a response that has undergone habituation.

Recognizing the perceptual world
3 aspects
Attention improves mental processing
Effort
Limited resources
Shifting overt vs covert
Overt behavior refers to the outside acts that follow the inside thought or intention and are apparent or obvious to others.
Covert behavior refers to the internal thoughts or motives that result in outward overt actions.
Mind reading
The capacity to judge and capture a person’s intentions, beliefs, and personality traits based on his or her behavior.
Processing involved in attentional shifts
Inhibition to decrease attentional resources to unwanted or irrelevant inputs.
Cues speed processing
The fluency with which the brain receives, understands and records the information
