• 1.

Weber's law is relevant to an understanding of:

• A.

Absolute thresholds

• B.

Difference thresholds

• C.

• D.

Sensory interaction

• E.

All of the above

B. Difference thresholds
Explanation
Weber's law states that the just noticeable difference (JND) between two stimuli is a constant proportion of the original stimulus intensity. In other words, it explains the smallest difference between two stimuli that can be detected by an individual. This concept is directly related to difference thresholds, as it deals with the ability to perceive changes in stimuli. Therefore, Weber's law is relevant to an understanding of difference thresholds.

The amplitude of electromagnetic waves determines the ______ of light.

• A.

Absolute threshold

• B.

Brightness

• C.

Hue

• D.

Difference threshold

• E.

Wavelength

B. Brightness
Explanation
The amplitude of electromagnetic waves determines the brightness of light. Amplitude refers to the height or intensity of the wave, and in the case of light waves, it directly affects how bright or dim the light appears. Higher amplitudes result in brighter light, while lower amplitudes result in dimmer light. Therefore, the amplitude of electromagnetic waves plays a crucial role in determining the overall brightness of light.

The process by which the lens changes shape so as to focus the image of an object on the retina is called

• A.

• B.

Accommodation

• C.

Convergence

• D.

Feature detectors

B. Accommodation
Explanation
Accommodation refers to the process by which the lens of the eye changes its shape in order to focus the image of an object on the retina. This adjustment allows for clear vision at different distances, as the lens becomes thicker or thinner to properly bend the incoming light rays. Adaptation refers to the adjustment of the eyes to different lighting conditions, convergence refers to the inward movement of the eyes to focus on a nearby object, and feature detectors are specialized cells in the visual system that respond to specific visual stimuli.

Rate this question:

• 4.

Ganglion cells converge to form

• A.

The basilar membrane

• B.

Bipolar cells

• C.

Auditory nerves

• D.

The optic nerve

D. The optic nerve
Explanation
Ganglion cells in the retina of the eye converge to form the optic nerve. The optic nerve is responsible for transmitting visual information from the retina to the brain. This convergence allows for the pooling of information from multiple ganglion cells, enhancing the sensitivity and resolution of visual perception. Therefore, the optic nerve is the correct answer as it accurately describes the pathway through which ganglion cells transmit visual signals to the brain.

Experiencing a green afterimage of a red object is most easily explained by:

• A.

The opponent process theory

• B.

The gate control theory

• C.

Weber's law

• D.

The Young-Helmholz theory

A. The opponent process theory
Explanation
The opponent process theory suggests that our visual system processes colors in pairs, with each pair consisting of an opposing color (red-green, blue-yellow, black-white). When we stare at a red object for a prolonged period, the red receptors in our eyes become fatigued, causing the opposing green receptors to become more active. This results in a green afterimage when we look away from the red object. This theory explains why we experience afterimages in colors that are opposite to the original stimulus.

• 12.

What is the process called in which one form of energy is changed into another. In sensation, the transforming of stimulus energies, such as touch and smells, into neural impulses our brain can interpret?

• A.

Priming

• B.

Transduction

• C.

Sensation

• D.

B. Transduction
Explanation
Transduction is the process in which one form of energy is converted into another. In the context of sensation, it refers to the conversion of stimulus energies, such as touch and smells, into neural impulses that can be interpreted by the brain. This process allows sensory information to be transmitted and processed by the nervous system, enabling us to perceive and make sense of the world around us.

If i am testing your sound absolute threshold what percentage of the time must you hear the minimum stimulus in order for the absolute threshold to have been found?

• A.

30%

• B.

100%

• C.

25%

• D.

50%

D. 50%
Explanation
In order to find the absolute threshold for sound, the minimum stimulus must be heard at least 50% of the time. This means that if the minimum stimulus is presented multiple times, it should be detected correctly in at least half of the trials. This percentage is considered as a reliable indicator of the absolute threshold for sound perception.

I have just walked into a very smelly house. After a while I do not notice the smell as bad or at all. What process makes this possible?

• A.

Sensory Deafness

• B.

• C.

• D.

Motor Fixing

Explanation
Sensory adaptation is the process that allows us to no longer notice a smell after being exposed to it for a while. This is because our sensory receptors become less responsive to the constant stimulus, causing us to perceive the smell as less intense or not at all. It is a mechanism that helps us focus on new or changing stimuli rather than being overwhelmed by constant sensory input.

Which of the following is NOT part of the eye?

• A.

Iris

• B.

Pupil

• C.

Retina

• D.

Stapes

• E.

Cornea

D. Stapes
Explanation
The stapes is not part of the eye. It is actually a bone in the middle ear that helps transmit sound vibrations to the inner ear. The iris, pupil, retina, and cornea are all structures that are found in the eye and play important roles in vision.

• 16.

What part of the eye is responsible for transduction of the visual stimulis

• A.

Iris

• B.

Retina

• C.

Cornea

• D.

Lens

B. Retina
Explanation
The retina is responsible for transducing visual stimuli. It contains specialized cells called photoreceptors, which convert light into electrical signals that can be processed by the brain. The retina is located at the back of the eye and is composed of several layers of cells, including rods and cones, which are responsible for different aspects of vision. These photoreceptor cells detect light and send signals to the brain through the optic nerve, allowing us to perceive and interpret visual information.

Rate this question:

Which of the below function better during the day and help us to focus better on objects?

• A.

Rods

• B.

Cones

• C.

Iris

• D.

Cornea

B. Cones
Explanation
Cones function better during the day and help us to focus better on objects. Cones are photoreceptor cells in the retina of the eye that are responsible for color vision and visual acuity. They are more active in well-lit conditions and are responsible for our ability to see fine details, distinguish colors, and focus on objects. Rods, on the other hand, are more sensitive to low light conditions and are responsible for peripheral vision and detecting motion. The iris is the colored part of the eye that controls the amount of light entering the eye, and the cornea is the transparent front part of the eye that helps to focus light onto the retina.

Rate this question:

• 18.

• A.

Night fishing

• B.

Enjoying a daytime stroll on the beach

• C.

Playing cards at a casino

• D.

Sleeping

A. Night fishing
Explanation
The correct answer is night fishing because fishing rods are commonly used during this activity. Fishing at night can be more productive as many fish species are more active during this time. The rods are essential for casting the bait or lure into the water and reeling in the fish once caught.

Parallel Processing is the ability of the brain to process many aspects of a problem or visual scene at the same time? Such as Color, Motion, Form and Depth.

• A.

True

• B.

False

A. True
Explanation
Parallel processing refers to the brain's ability to process multiple aspects of a problem or visual scene simultaneously. This means that the brain can process information related to color, motion, form, and depth all at once. This allows for a more efficient and comprehensive understanding of the environment. Therefore, the given statement that parallel processing is the ability of the brain to process many aspects of a problem or visual scene at the same time is true.

• A.

Recognizing a stimulus; interpreting a stimulus

• B.

Seeing; hearing

• C.

Detecting a stimulus; recognizing a stimulus

• D.

Interpreting a stimulus; detecting a stimulus

C. Detecting a stimulus; recognizing a stimulus
Explanation
Sensation refers to the process of detecting a stimulus, such as seeing or hearing, while perception involves recognizing and interpreting that stimulus. In other words, sensation is the initial step of detecting the presence of a stimulus, while perception involves understanding and making sense of that stimulus.
