• C) Bipolar cells
• D) Ganglion cells Correct Answer s: A, B Rationale: Rods and cones are the two main types of photoreceptors that detect light; bipolar and ganglion cells are involved in transmitting visual information.

Additional Questions

14. Which visual processing pathway is associated with

Correct Answer s: A, C Rationale: Higher frequencies indeed stimulate the base of the cochlea, and binaural hearing helps with sound localization; the semicircular canals are related to balance, not hearing.

18. Fill in the blank: The __________ phenomenon describes the tendency for the human brain to fill in gaps in incomplete visual information. Correct Answer : Gestalt Rationale: The principles of Gestalt psychology emphasize how we perceive wholes instead of just the sum of parts by filling in visual gaps.
19. True or False: The fovea is the region of the retina with the highest concentration of rods. Correct Answer : False Rationale: The fovea is primarily composed of cones, which are responsible for high acuity color vision.
20. Which of the following list the steps of the perceptual process in the correct order?
    • A) Transduction, interpretation, sensation, perception
    • B) Sensation, transduction, perception, interpretation
    • C) Sensation, perception, transduction, interpretation
    • D) Transduction, sensation, perception, interpretation Correct Answer : B Rationale: The correct order begins with sensation, followed by transduction, interpretation, and finally perception.
21. Fill in the blank: The concept of __________ asserts that our perception of reality is not merely a sum of sensory

inputs but is actively constructed by our cognitive processes. Correct Answer : Constructivism Rationale: Constructivism posits that perception is constructed through cognitive processes, shaping how we interpret sensory information.

22. Which factors can cause light adaptation? (Select all that apply)
    • A) Moving from darkness into bright light
    • B) Staying in a brightly lit area for extended periods
    • C) Moving from bright light into darkness
    • D) Changes in pupil size Correct Answer s: A, B, D Rationale: Light adaptation occurs when a person transitions from low to high-light environments, which involves accommodating changes in pupil size and acclimatizing to brightness.
23. True or False: The human eye can only perceive a small fraction of the electromagnetic spectrum, specifically the visible light spectrum. Correct Answer : True Rationale: The human eye is sensitive only to a small portion of the electromagnetic spectrum known as visible light.
24. Fill in the blank: The __________ threshold is the smallest amount of change in stimulus intensity that can be detected 50% of the time. Correct Answer : Just noticeable (JND) Rationale: The just noticeable difference refers to the minimal change in a stimulus that can be reliably detected.

• B) Auditory canal
• C) Eustachian tube
• D) Semicircular canals Correct Answer : C Rationale: The Eustachian tube connects the middle ear to the throat and helps equalize air pressure.

29. Fill in the blank: The theory of __________ suggests that the perception of pain is regulated by both physical and psychological factors. Correct Answer : Gate control Rationale: The gate control theory posits that psychological factors influence pain perception through a 'gate' mechanism in the spinal cord. Multiple Choice: Which of the following structures in the eye is primarily responsible for the perception of color? A) Retina B) Cornea C) Lens D) Iris Correct Answer : A) Retina Rationale: The retina contains photoreceptor cells called cones, which are sensitive to color. Fill-in-the-Blank: The phenomenon where the perception of a stimulus is influenced by previous experiences and expectations is known as _. Correct Answer : Top-down processing Rationale: Top-down processing involves the influence of knowledge and expectations on the perception of stimuli.

True/False: The absolute threshold refers to the minimum intensity of a stimulus that can be detected 50% of the time.
