Sensation and Perception is one of the 8 main chapters in our Federal Board FSC Psychology question bank (11th class), and about 8% of its real questions come from it. Tayyari Karo has 23 real questions on this chapter from 2023 to 2026; 13 are multiple choice and marked instantly, and the rest are short and long questions with a model answer. By difficulty: 19 medium, 4 easy.
Work through the questions below, then open the explanation for each one. Redo the ones you missed a few days later.
These are real past-paper questions. Think of your answer first, then open the explanation.
The part of the eye that converts electromagnetic energy of light into useful information for the brain is:
Answer: A. Retina
The retina contains photoreceptors (rods and cones) that convert light energy into neural signals for the brain.
Which part of ear transmits the sound waves to a snail shaped tube, cochlea?
Answer: B. Middle
The middle ear (via the ossicles) transmits vibrations onward to the cochlea in the inner ear.
A boy with blue eyes could be described as having blue pigment in his:
Answer: B. Iris
Eye colour comes from pigment in the iris, the coloured muscular ring surrounding the pupil.
Auditory canal is a part of:
Answer: C. Outer ear
The auditory (ear) canal channels sound from the pinna to the eardrum and is part of the outer ear.
A physical stimulus that consistently produce error in perception is called:
Answer: A. Illusion
An illusion is a real physical stimulus that is consistently misperceived in a predictable, distorted way.
Which of the following is NOT a monocular depth cue?
Answer: C. Retinal disparity
Retinal disparity requires both eyes and is a binocular cue; texture gradient, interposition and light/shadow are monocular cues.
What is sensation? How do we see colours?
Sensation is the process by which sensory organs (eyes, ears, skin, nose, tongue) detect physical energy/stimuli from the environment (light, sound waves, pressure, chemicals) and convert it into neural signals sent to the brain.
Colour vision: light of different wavelengths enters the eye and stimulates cone cells in the retina, which are of three types, each maximally sensitive to a different wavelength range — roughly corresponding to red, green, and blue light (trichromatic theory). The brain compares the relative activation of these three cone types and combines the signals to produce the perception of the full range of colours we see.
Explain the binocular cues used for depth and distance perception.
Binocular cues require the use of both eyes together to judge depth/distance:
• Retinal (binocular) disparity — because the two eyes are set slightly apart, each retina receives a slightly different image of the same scene; the brain uses the degree of difference between these two images to judge distance — greater disparity means the object is closer.
• Convergence — as an object comes closer, the eye muscles must turn the eyes more inward (converge) to keep it in focus; the brain uses the degree of muscular tension/convergence as a cue to judge how near the object is.
