Exam 1 review Flashcards
What is something that cannot be fully explained by the behaviorist approach?
- Not a fully fledged explanation of behavior (you can learn without a reward.)
- Acquisition of language
- Creativity of language
WHERE pathway??
- Dorsal= “D” for direction
- objects in space
WHAT pathway??
- Ventral= “V” for Visual
- what objects are
Feature net model
- Layers of “detectors” that respond to specific features; each layer processes more complex information
Recognition by components theory
- suggests that humans recognize objects by breaking them down into their basic 3D geometric shapes, called “geons,”
Top-Down processing
- Using models, ideas, and expectations to interpret sensory information
- Is that something i’ve seen before?
Bottom up processing:
- taking sensory information and then assembling and integrating it
- What am I seeing?
Gestalt principles
- Proximity: close objects are perceived as a group
- Similarity: similar objects are perceived as a group
- Closure: we complete missing parts
- symmetry and order: symmetrical and orderly elements are perceived as a group
- Common fate: objects moving together are perceived as a group
- Figure ground: we perceive objects in the foreground or back
- Continuity: elements on a line or curve are related
Does the whole equal the sum of its parts?
No, the whole is greater than the sum of its parts
Visual cells
- The area of the visual world over which stimulation affects a specific cell’s response.
- Some are orientation sensitive
- some are sensitive to when/where lines end
(think of the cat with an electrode in his brain)
Attentional sets
- Improved processing for items you are attuned to, or ‘set to process
- What you are expecting or attending to can affect what ‘captures’ your attention
Visual Neglect/ Unilateral Neglect syndrome
- Ignores left side of visual world
- Won’t shave left side of face, won’t eat from the left side of the plate
- Damage to the parietal lobe (usually right side)
Balint’s syndrome (simultanagnosia)
- Completely object based deficit
- Bilateral parietal damage
- can only see one object at a time
What is the phonological loop?
the speech- and sound-related component of working memory and holds verbal and auditory information
What are the components of the phonological loop?
- phonological store
- articulatory control process
What model is the phonological loop a component of?
Baddeley’s working memory model.
what is the phonological similarity effect?
poor serial recall performance for lists composed of similar‐sounding words compared to lists of dissimilar‐sounding items.
Partial report experiment
a psychological study that examines how people recall information from a brief visual display. In this experiment, participants are shown an array of letters or numbers and then asked to recall a specific row of the display. The row to recall is indicated by a tone played after the display disappears.
Spatial cueing experiment
arrow points to the shit and sometimes it lies and sometimes it doesn’t and also sometimes theres no arrow
Frontal
in the front (haha)
- planning organizing, inhibition
Parietal
up but not the temporal lobe
- spatial knowledge, proprioception, sensory processing, language
Temporal
- Right by the ear
- Auditory perception, language, visual, and verbal memory
Occipital
the back of the head
- visual processing
What provides evidence for late selection?
all information is processed for its meaning and only selected information is processed past this
- cocktail party effect
Stimulus>sensory registration> semantic processing (attention)> response
