Visual Attention
Visual Attention
Do individuals respond to visual stimuli of different colors at the same speed. True or False??
False.
Which perception hypothesis states that people perceive their environment in terms of their ability to act on it?
Action-specific
A person looks at the moon and some clouds at night. They perceive the moon moving through the clouds. This is an example of
induced motion.
In order to distinguish between wavelengths independent of light intensity, one must have at least how many visual pigment(s)?
Two
Which term is defined as depth perception created by input from both eyes?
Stereoscopic depth perception
Which researcher described attention as “the taking possession by the mind, in clear and vivid form, of one out of what seem several simultaneously possible objects or trains of thought.”
William James in his 1890 book The Principles of Psychology.
When expert gymnasts close their eyes while performing a somersault, they perform better or more poorly...?
more poorly because they could not make “in-air” corrections.
A “point-light walker” wears lights on different body locations. When viewed in a dark room, an observer would perceive a(n)
person when the point-light walker is moving
Blue and yellow paints, mixed together, yield
Green
Where is Motion parallax applied and widely used
is widely used to create depth in cartoons and video games.
When a person scans a visual scene, they usually make about how many fixation(s) per second.?
Three
When novices close their eyes when trying a somersault performance is
their performance is not degraded as much as is the performance of experts.
As a person runs through the park, the flow signals that they are moving and not the environment. Gibson calls this
the global optic flow.
Adding more white to a color changes the color’s
Saturation
Fox et al. (1980) found that the ability to use binocular disparity develops between what age
3 ½ and 6 months
One aspect of the visual system that helps us select specific information from the environment for processing is
the concentration of cones in the fovea.
In Janzen and vanTurennout’s study of using landmarks as “decision points” in navigating through a museum, participants had greater activation in what brain areas
had greater brain activation in the parahippocampal gyrus for “decision points” than “non-decision points.”
In an apparent motion demonstration, two pictures are used. In one picture, a fist is located behind a board; in the other, the fist is located in front of the board at the same height. When rapidly alternating between these pictures, what apparent motion would result?
The fist would appear to “magically” pass through the board.
A person wants to create a stimulus that will produce an afterimage of a red heart shape against a white background. They should make the heart
Green
As a person looks down a railroad track, they perceive the sides of the tracks as becoming closer as the distance increases. This is an example of
perspective convergence
In an fMRI study by Datta and DeYoe (2009), participants covertly shifted their attention within a display. This shifting of attention resulted in the activation of different or the same brain regions?
different brain regions because the participant was attending to different locations
Proposed functions of mirror neurons include their role in
aiding interpretation of facial expressions.
In monkeys, real-motion neurons have been located in what area of the brain
the extrastriate cortex
A person enters a supermarket that is lit by red lights. After fifteen minutes, they enter the produce section and finds some red apples to purchase. They are able to see these apples as red because they have undergone
Undergone chromatic adaptation.
A person is standing on a rooftop in a city. The buildings closer to them look sharper, and the buildings in the distance look hazier. This is an example of which depth cue?
Atmospheric perspective
