Question

9 multiple choice 1 point
why are there blind spots in our field of vision?
because there is an area of the back of the eye that contains no sensory receptor cells, only the sensory receptor cells axons
because of the lateralization of the brain
because there is a tiny irregularity of the pupil in both eyes
because there are always areas of our visual field that we dont pay attention to

10 multiple choice 1 point
the amplitude of a lightwave corresponds to which of the following perceptions?
volume
brightness
color
pitch

Explanation:

Analyze Question 9

This question asks for the physiological reason behind the blind spot in our visual field.

• The blind spot occurs where the optic nerve leaves the back of the eye (retina) to carry visual information to the brain.
• At this specific location, there are no photoreceptors (rods or cones) to detect light, only the axons of the ganglion cells forming the optic nerve.
• Therefore, the first option is correct: "because there is an area of the back of the eye that contains no sensory receptor cells, only the sensory receptor cells' axons".
• We apply the concept of Sensation and Perception to understand how physical structures in the eye limit visual reception.

Analyze Question 10

This question asks which psychological perception corresponds to the physical amplitude of a light wave.

• In the study of light waves, wavelength determines the hue or color we perceive.
• The amplitude (height) of the light wave determines the intensity of the light, which we perceive as brightness.
• Volume and pitch are auditory perceptions related to sound waves, not light waves.
• Therefore, the second option is correct: "brightness".

Answer:

Question 9

• because there is an area of the back of the eye that contains no sensory receptor cells, only the sensory receptor cells' axons (Correct answer)
• because of the lateralization of the brain
• because there is a tiny irregularity of the pupil in both eyes
• because there are always areas of our visual field that we don't pay attention to

Question 10

• volume
• brightness (Correct answer)
• color
• pitch
