Perceptual Development (W10, L1) Flashcards
(18 cards)
What is an example of how visual perception does not work like a camera?
Contextual information biases make your brain guess information about the picture
Example: gold & white vs. black and blue dress.
How is vision described in terms of its activity?
Vision is active, not passive, using previous knowledge.
How does the perception of light intensity differ from the perception of color?
The way we perceive light intensity is different from the way we perceive color.
What does ‘wired to perceive’ refer to in barnyard chicks?
Barnyard chicks appear to have an innate ability to identify threats based on pattern and movement.
How does auditory perception differ from a microphone?
Auditory perception is active, using previous knowledge and experience to interpret audio.
What is categorical perception?
The tendency to group incoming sensory information along a continuum into discrete categories.
Give an example of categorical perception in color.
Categorizing colors, e.g., when blue slowly gradients to green.
Give an example of categorical perception in sound.
Sound when ‘ba’ gradually transitions into ‘pa’.
What are language bound listeners less able to do?
They are less able to hear differences in languages they were not exposed to.
What is perceptual narrowing?
Increasing ability to discriminate relevant things encountered frequently and decreasing ability for less relevant stimuli.
Provide a visual example of perceptual narrowing.
Improved ability to perceive human faces while declining ability to perceive monkey faces.
At what age can infants perceive differences in various animal faces?
At 6 months, infants can perceive differences in human, monkey, and sheep faces.
What happens to face perception by 9 months?
Perception narrows to mostly just humans.
What is the speech perception ability of infants at 6 months?
They can discriminate between phonemes of all languages.
What happens to speech perception by 12 months?
They lose the ability to discriminate between phonemes of all languages.
What is multimodal integration?
Understanding the correspondence between different modes (senses).
What ability do newborns seem to have regarding sensory integration?
They can pair vision and sound, and also vision and touch experiences.
What is the McGurk effect?
Hearing the ‘BA’ or ‘FA’ sound based on the visual input while hearing the same audio.
