Perceptual Development Throughout The Lifespan Flashcards
Perception
The process of assigning meaning to the sensation
Sensation
The process of registering stimulation and transmitting that information to cortical brain centers
Habituation
Is the decreasing attention to a familiar stimulus
Perception is really intermodal. What does that mean?
It is the result of coordination and communication among the sensory perceptual systems
Sensitivity to a perceptual stimulus is measured by the…
Absolute threshold
True or false?
Poor visual acuity in newborns is because the muscles that control the lens, the part of the eye that has to reflect light on to the retina, are weak.
True
True or false?
Visual acuity improves slowly over the first four months of life.
False
Visual acuity improves rapidly over the first four months of life
Who developed the visual cliff apparatus to determine infants and toddlers depth perception?
Gibson and Walk in 1960
Perceptual constancy
And important characteristic of visual perception where we can see stability shape size brightness and color of objects in our visual field
Size constancy
Objects we are familiar with seem to appear the same size despite changes in the distance between us and the object
Shape constancy
Objects appear to be the same shape despite changes in their orientation toward the viewer
Brightness or light in this constancy
Objects appear to stay the same brightness despite changes in the amount of light falling on them
Color constancy
Thank you up an object appears to stay the same despite changes in background lighting
Studies of color perception using the habituation paradigm report that very young infants see color and have him at your ability to perceive color by what age?
2 to 3 months of age
What is selective looking in infants?
Scanning the borders and edges of objects in a visual stimulus
