Chapter 7 Flashcards
What is perception?
- Interpretation of sensation
Selective perception is termed?
-Attention
True or false: sensitivity to touch can be demonstrated in the womb.
- True
When Is a sense of smell evident? When is a sense of taste evident?
- Smell= prenatally
- Taste= evident at birth (newborns react with facial expressions)
At what age does a fetus show sensitivity to sound? At what age post-birth does a baby’s sense of hearing improve?
- 28 weeks in the womb- evident
- 6 moths post birth hearing improved significantly
Babies are soothed by _____ frequency sounds
- Low
By ___ months babies can use sound to locate direction and distance
- 7
Newborns can perceive _____ but few colours
- Contrast
By 3 to 4 months, colour vision improves in babies to the same as adults due to the maturation of colour ______ cells
- Receptor
What is the visual acuity of a newborn? What is visual acuity?
- 20/400 to 20/800
- Visual acuity is the clarity of visual images
Why is the visual acuity of a newborn so poor?
- The neural circuits that govern visual accommodation (flexing of the lens) are not functional in a newborn
True or false: by 1 year, visual acuity is the same as adults
- True
Habituation studies reveal that at 1 month old, babies can differentiate blue & _______, and ____ from green
- Gray
- Green
At __ to __ months of age, infants begin to organize visual stimuli together
1 to 3
When perceiving faces, 1 month olds tend to focus on the ____ of the face/ head, whereas 3 month olds tend to look at the ____ of the face
- Edges
- Features (eyes, nose, lips)
At age 7 months, babies are able to perceive ______. This has been proved by the visual cliff experiment, in which an infant shows changes in heart rate when exposed to a sharp drop off.
- Depth
The ability to realize that cues from different senses go together is called
Intermodal perception
What are exploratory intermodal relations?
- Infants’ inborn ability to spatially relate among sensory modes
The ability to develop mental representations that bridge haptic (touch) and visual model as well as auditory and visual modes is called intermodal ________
- Representation
Detection of sensory information is termed?
Sensation
Inattention, hyperactivity, and impulsivity are symptoms of what disorder?
- Attention Deficit Hyperactivity Disorder (ADHD)
In people with ADHD, the __ frontal lobe seems to be smaller, or the lobes appear to be _______
- Right
- Symmetrical
Why would stimulants work as a treatment for people with ADHD?
- Stimulants speed up the inhibitory functions in the basal ganglia. The basal ganglia processes attention tasks as a filter, and it’s functioning is slowed in people with ADHD. Thus, stimulants would speed up these inhibitory functions.
