Question 1

The reason stroboscopic motion was a topic of research for Gestalt psychologists is because

Accepted Answer

Stroboscopic motion refers to the optical illusion where a series of static images, when shown in rapid succession, appear to be moving. Gestalt psychologists were interested in this phenomenon as it demonstrated how our minds perceive a sequence of separate images as a continuous motion, illustrating the principle of perceptual organization where the whole is different from the sum of its parts.

Question 2

In order to perceive object constancy,your brain needs to understand the relationship between the object and one other factor.In the case of size constancy,you understand that the car you see approaching is not

Accepted Answer

Size constancy refers to our ability to perceive the size of an object as constant even when its distance from us changes. The correct factor related to size constancy is the distance of the object from the observer, as our brain compensates for the change in distance to maintain our perception of the object's consistent size.

Question 3

Ayanna made a flipbook by drawing a stick figure on each piece of paper in a slightly different position.When she flipped the pages,the stick figure appeared to be walking across the pages.Ayanna's flipbook illustrates the principle of

Accepted Answer

Ayanna's flipbook illustrates the principle of stroboscopic motion, where a series of static images shown in rapid succession create the illusion of motion. This is the same principle that allows movies and animations to appear as if they are moving.

Question 4

When Danni was standing directly in front of a door,it appeared rectangular,with right angles at each corner.When the door was opened part way,the door appeared to Danni to change
Shape,with some of the corners appearing as sharper angles and other corners appearing
Wider.However,Danni knew that the door had not actually changed shape because of

Accepted Answer

Shape constancy refers to the phenomenon where the perceived shape of an object remains constant despite changes in the angle of view, distance, or lighting. In this scenario, even though the door's appearance changes when viewed from different angles as it opens, Danni understands that its actual shape hasn't changed, demonstrating shape constancy.

Question 5

The auditory neurons extending from the ________ reach out with their axons to the primary auditory cortex in the ________.

Accepted Answer

The auditory neurons extend from the thalamus and reach out with their axons to the primary auditory cortex, which is located in the temporal lobe.

Question 6

The primary auditory cortex is located in which brain lobe?

Accepted Answer

The primary auditory cortex is located in the temporal lobe, specifically within the superior temporal gyrus.

Question 7

Ayelet is trying to draw a picture of two people down the street from each other.No matter how carefully she tries to draw them both the same size,the person who is supposed to be farther away appears much taller than the nearer person.You could explain that the depth cue of ________ size means that she will need to draw a ________ image of the person who is supposed to be farther away.

Accepted Answer

Relative size is a depth cue that suggests objects farther away will appear smaller than those closer to the viewer. Therefore, to make the person who is supposed to be farther away appear correctly, Ayelet will need to draw a smaller image of that person.

Question 8

Sound waves cause the ________ to vibrate.

Accepted Answer

Sound waves cause the eardrum to vibrate, which is the initial step in the process of converting sound waves into electrical signals that can be interpreted by the brain.

Question 9

Dogs can hear higher-frequency sounds than people can.This fact suggests that there is a physical difference inside the

Accepted Answer

The answer of Dogs can hear higher-frequency sounds than people...

Question 10

Regarding visual illusions,which of the following statements is most accurate?

Accepted Answer

Illusions help reveal normal perceptual processes. Illusions occur because our brains make assumptions and interpretations about the visual information we receive, based on previous experiences and knowledge. Therefore, illusions can provide insights into how our brains perceive and interpret visual information in everyday life.

Question 11

Gervase is staring at the blades of his ceiling fan.When he turns off the fan,he is surprised that the blades appear to be rotating in the opposite direction.To reassure Gervase that he is not hallucinating,you could tell him about

Accepted Answer

This phenomenon is known as motion aftereffects. It occurs when prolonged viewing of a moving object (like the spinning fan blades) causes stationary objects seen immediately afterward to appear to be moving in the opposite direction. This happens because of the temporary adaptation of the motion detectors in the visual system.

Question 12

The four kinds of object constancy are

Accepted Answer

The four kinds of object constancy are size, shape, color, and brightness constancy. These psychological processes allow us to perceive objects as having constant properties even though the sensory information we receive about them can vary widely.

Question 13

Li-Ting is painting a picture of a vase of flowers placed in front of a book case.She paints the vase and then,right next to it,half of a book.When Bijal looks at the painting,she sees the book as being ________ the vase because of ________.

Accepted Answer

Occlusion is a visual cue that occurs when one object partially covers another, indicating that the covered object is behind the one in front. Since the book is painted as being partially covered by the vase, it appears to be behind the vase due to occlusion.

Question 14

Prolonged exposure to movement in one direction ________ the motion detectors responsive to that direction.When the movement stops,the baseline firing rate of detectors for the
Opposite direction of motion will be ________ than the firing rate for the detectors that
Responded to the prolonged movement,leading to motion aftereffects.

Accepted Answer

Prolonged exposure to movement in one direction fatigues the motion detectors for that direction. When the movement stops, the baseline firing rate of detectors for the opposite direction will be higher than the firing rate for the detectors that responded to the prolonged movement, leading to motion aftereffects. This is why, for example, after looking at a waterfall for a while and then looking away, you might see stationary objects appear to move in the opposite direction.

Question 15

According to stroboscopic motion,when two vertical lines are flashed on a screen at different intervals,we perceive the lines in different ways.To be perceived as one line moving continuously from side to side,the interval between the lines should be

Accepted Answer

The answer of According to stroboscopic motion,when two vertical lines...

Question 16

The Shepard's Table illusion is an example of

Accepted Answer

The Shepard's Table illusion demonstrates how the brain's assumptions about the physical world, such as perspective and depth cues, can lead to misinterpretations of visual information, illustrating how our perception can be fooled.

Question 17

The reason we are able to perceive still images flashed rapidly on a screen as images in motion is because the previous image persists on the retina for around 70 milliseconds,so we
Don't perceive the gap between images.This phenomenon is called

Accepted Answer

This phenomenon is called stroboscopic motion, where still images flashed in quick succession appear to be moving due to the persistence of vision, where the previous image stays on the retina for a short period, allowing a smooth transition between images.

Question 18

There are several steps involved in the process of transforming a sound into a signal that can be understood by the brain.Which of the following displays these steps in the correct order?

Accepted Answer

The correct sequence for transforming a sound into a signal that the brain can understand starts with a sound wave, which causes the eardrum to vibrate. This vibration then creates a pressure wave in the fluid of the inner ear.

Question 19

The coiled,bony,fluid-filled tube in the inner ear that houses the sensory receptors is called the

Accepted Answer

The cochlea is the coiled, bony, fluid-filled tube in the inner ear that contains the sensory receptors for hearing.

Question 20

Hearing is also called

Accepted Answer

Hearing is referred to as audition, which is the sense or act of hearing. Olfaction pertains to the sense of smell, gustation to the sense of taste, and the occipital term is often associated with the occipital lobe in the brain, which is primarily involved in visual processing.
