Which of the following best describes the difference between sensation and perception?

Accepted Answer

Sensation is the detection of external stimuli by sensory organs, while perception is the interpretation of those signals by the brain.

Question 2

According to Weber's Law, the just noticeable difference (JND) for a stimulus is:

Accepted Answer

A constant proportion of the original stimulus intensity.

Question 3

Which outcome in Signal Detection Theory represents a situation where a stimulus is present but not detected?

Accepted Answer

Miss

Question 4

A person is exposed to a faint sound that is below their absolute threshold. Later, they respond more quickly to a related sound. This is an example of:

Accepted Answer

Priming

Question 5

Which Gestalt principle explains why we perceive a series of broken lines as a continuous shape?

Accepted Answer

Continuity

Question 6

If a person is shown a series of animal pictures before viewing an ambiguous image, they are more likely to interpret the image as an animal. This demonstrates:

Accepted Answer

Perceptual set

Question 7

Which structure in the eye is responsible for focusing light onto the retina and can change shape to accommodate near or far objects?

Accepted Answer

Lens

Question 8

A person with myopia (nearsightedness) has difficulty seeing distant objects because:

Accepted Answer

Their eyeball is too long, causing images to focus in front of the retina.

Question 9

According to the trichromatic theory of colour vision, humans perceive colour based on:

Accepted Answer

Three types of cones sensitive to short, medium, and long wavelengths.

Question 10

Which monocular depth cue is illustrated when objects closer to you appear to move faster than distant objects as you look out a moving train window?

Accepted Answer

Motion parallax

Question 11

The basilar membrane in the cochlea is involved in pitch perception. According to place theory, high-frequency sounds stimulate hair cells:

Accepted Answer

Near the ossicles at the base of the cochlea

Question 12

Which part of the ear is primarily responsible for converting sound waves into neural signals?

Accepted Answer

Cochlea

Question 13

Sound localization relies on which two main cues?

Accepted Answer

Time difference and intensity difference between ears

Question 14

The vestibular system helps maintain balance by detecting:

Accepted Answer

Changes in head position and movement in three planes

Question 15

Which type of touch receptor is most densely packed in the fingertips, allowing for high tactile acuity?

Accepted Answer

Mechanoreceptors

Question 16

Gate control theory explains pain perception by suggesting:

Accepted Answer

Large fibers can inhibit pain signals by 'closing the gate' in the spinal cord.

Question 17

Which taste sensation is most closely associated with protein-rich foods?

Accepted Answer

Umami

Question 18

The olfactory system is unique among sensory systems because:

Accepted Answer

It connects directly to the limbic system, influencing emotion and memory.

Question 19

Which phenomenon demonstrates how visual information can alter auditory perception, such as when seeing lips move changes what we hear?

Accepted Answer

Multimodal integration

Question 20

A person who can rapidly identify 'Greebles' after training shows increased activity in which brain region associated with face recognition?

Accepted Answer

Fusiform face area (FFA)
