Sensation And Perception MCQs With Answers - Quiz

This quiz entails the topics related to the perception and sensation chapter. Kindly attempt these MCQs with answers and revise the topics you have not fully learned. These two processes are important parts of psychology that are separated but related. The sensation is the process through which our receptors receive information from the physical world, whereas perception is the process through which our brain organizes and interprets those sensations. Let's test your knowledge of sensation and perception with the following quiz.


Questions and Answers
  • 1. 

    Which process means conversion of one form of energy to another? 

    • A.

      Induction 

    • B.

      Tranduction 

    • C.

      Transalation

    • D.

      Bleaching

    Correct Answer
    B. Tranduction 
    Explanation
    Transduction is the process of converting one form of energy into another form. It involves the conversion of physical or chemical stimuli into electrical signals that can be processed and interpreted by the body or a system. This process is commonly found in sensory systems, where stimuli such as light, sound, or pressure are converted into electrical signals that can be transmitted to the brain for perception and interpretation.

    Which of the following is the correct sequence of the light passing through the eye?

    • A.

      Cornea, Pupil, Iris, lens 

    • B.

      Cornea, Iris, pupil, lens 

    • C.

      Pupil, Cornea, Iris, lens 

    • D.

      Pupil, lens, iris, Cornea 

    Correct Answer
    A. Cornea, Pupil, Iris, lens 
    Explanation
    The correct sequence of the light passing through the eye is as follows: Cornea, Pupil, Iris, lens. The cornea is the transparent outer layer of the eye that helps to focus light. The pupil is the opening in the center of the iris that allows light to enter the eye. The iris is the colored part of the eye that controls the size of the pupil and regulates the amount of light entering the eye. The lens is located behind the iris and helps to further focus the light onto the retina at the back of the eye.

    Human olfactory receptors can detect only substances between the molecular weight of?

    • A.

      20 to 350

    • B.

      50 to 150

    • C.

      15 to 300

    • D.

      50 to 290

    Correct Answer
    C. 15 to 300
    Explanation
    Human olfactory receptors are responsible for detecting and distinguishing different smells. These receptors are specialized to recognize specific molecules in the air that enter the nasal cavity. The molecular weight of a substance can affect its volatility and ability to be detected by these receptors. The range of 15 to 300 for the molecular weight suggests that the receptors are capable of detecting a wide range of substances, from smaller molecules like certain gases to larger molecules like some organic compounds. This range allows for the detection of a diverse array of smells in the environment.

    Which of the following cells are responsible to boundaries of the object according to feature detection theory?

    • A.

      Complex

    • B.

      Simple 

    • C.

      Hypercomplex 

    • D.

      Compound

    Correct Answer
    B. Simple 
    Explanation
    According to feature detection theory, simple cells are responsible for detecting boundaries of objects. Simple cells are found in the primary visual cortex and respond to edges and lines of specific orientations. They have receptive fields that are sensitive to specific features, such as edges with a particular angle or orientation. These cells play a crucial role in processing visual information and detecting the boundaries and contours of objects.

    What are the primary colors mentioned in the Trichromatic theory ?

    • A.

      Blue, Green, Yellow 

    • B.

      Red, Blue, Yellow

    • C.

      Yellow, green, black 

    • D.

      Red, Blue, Green 

    Correct Answer
    D. Red, Blue, Green 
    Explanation
    The Trichromatic theory states that the primary colors of light are red, blue, and green. According to this theory, our eyes have three types of color receptors that are most sensitive to these three colors. By combining different amounts of red, blue, and green light, our eyes can perceive a wide range of colors. This theory is widely accepted and forms the basis for color reproduction in various devices such as televisions and computer screens.

    Olfactory bulb is located below which lobe?

    • A.

      Frontal lobe 

    • B.

      Frontal and Temporal 

    • C.

      Temporal 

    • D.

      Occipital Lobe 

    Correct Answer
    A. Frontal lobe 
    Explanation
    The olfactory bulb is located below the frontal lobe. This is because the olfactory bulb is responsible for processing smell information, and it is situated in the front part of the brain, close to the nasal cavity. The frontal lobe is involved in various cognitive functions such as decision-making, problem-solving, and motor control.

    No, matter from which angle I see the book lying on my table, I always perceive it as rectangle, which phenomenon of perceptual constancy helps explain this?

    • A.

      Orientation 

    • B.

      Shape 

    • C.

      Location

    • D.

      Size 

    Correct Answer
    B. Shape 
    Explanation
    Perceptual constancy refers to the ability of our brain to perceive objects as having a consistent shape, size, color, or location regardless of changes in the viewing angle or distance. In this case, the fact that the book appears as a rectangle from any angle suggests that the phenomenon of shape constancy is at play. Shape constancy allows us to recognize and interpret the book's shape as a rectangle, regardless of the perspective from which we view it.

    • C.

      Watson 

    • D.

    Where does transduction in the olfaction occur?

    • A.

      Hair Cells 

    • B.

      Thalamus 

    • C.

      Olfactory Bulb 

    • D.

      Nasal Cavity 

    Correct Answer
    D. Nasal Cavity 
    Explanation
    Transduction in olfaction occurs in the nasal cavity. The nasal cavity contains specialized cells called olfactory receptor cells, which are responsible for detecting and transducing odor molecules into electrical signals. These electrical signals are then sent to the olfactory bulb in the brain, where further processing and interpretation of the smells occur. Therefore, the nasal cavity is the site where transduction takes place in the olfaction process.

    Direct theory of perception was given by?

    • A.

      Gregary 

    • B.

      Gibson 

    • C.

      Watson

    • D.

      Kohler 

    Correct Answer
    B. Gibson 
    Explanation
    The correct answer is Gibson. Gibson is known for his direct theory of perception, which suggests that perception is a direct and immediate process that does not require any cognitive processes or inferences. According to Gibson, perception is based on the information that is available in the environment, and our sensory systems are capable of directly picking up this information without the need for interpretation or mental processing. This theory emphasizes the importance of the environment and the role it plays in perception.
