Which of the following is NOT a basic sensory modality?

  1. Vision

  2. Hearing

  3. Taste

  4. Smell

  5. Balance


Correct Option: E
Explanation:

Balance is a sense that helps us maintain our equilibrium and orientation in space, but it is not considered a basic sensory modality like vision, hearing, taste, and smell.

The process by which sensory receptors convert physical stimuli into electrical signals is known as:

  1. Transduction

  2. Adaptation

  3. Sensation

  4. Perception

  5. Integration


Correct Option: A
Explanation:

Transduction is the initial step in sensory processing, where specialized cells called sensory receptors transform physical stimuli into electrical signals that can be interpreted by the nervous system.

The minimum amount of a stimulus that can be detected by a sensory receptor is known as the:

  1. Absolute threshold

  2. Difference threshold

  3. Weber's law

  4. Fechner's law

  5. Sensory adaptation


Correct Option: A
Explanation:

The absolute threshold refers to the minimum intensity of a stimulus that can be detected by a sensory receptor, allowing us to distinguish it from no stimulus at all.

The ability of sensory receptors to adjust their sensitivity to different levels of stimulation over time is known as:

  1. Sensory adaptation

  2. Transduction

  3. Sensation

  4. Perception

  5. Integration


Correct Option: A
Explanation:

Sensory adaptation is the process by which sensory receptors become less responsive to constant or unchanging stimuli over time, allowing us to focus on new or changing stimuli.

The principle that states that the just noticeable difference (JND) between two stimuli is a constant proportion of the original stimulus is known as:

  1. Weber's law

  2. Fechner's law

  3. Absolute threshold

  4. Difference threshold

  5. Sensory adaptation


Correct Option: A
Explanation:

Weber's law states that the JND is a constant proportion of the original stimulus, meaning that the amount of change required to detect a difference is proportional to the intensity of the original stimulus.

The relationship between the physical intensity of a stimulus and the perceived intensity of that stimulus is described by:

  1. Weber's law

  2. Fechner's law

  3. Absolute threshold

  4. Difference threshold

  5. Sensory adaptation


Correct Option: B
Explanation:

Fechner's law states that the perceived intensity of a stimulus is proportional to the logarithm of its physical intensity, suggesting a logarithmic relationship between the two.

The process of organizing and interpreting sensory information to create a meaningful representation of the world around us is known as:

  1. Sensation

  2. Perception

  3. Transduction

  4. Adaptation

  5. Integration


Correct Option: B
Explanation:

Perception involves the active organization and interpretation of sensory information to form meaningful representations of the environment, allowing us to understand and interact with the world around us.

The tendency to perceive objects as wholes rather than as collections of individual parts is known as:

  1. Gestalt psychology

  2. Figure-ground perception

  3. Perceptual organization

  4. Depth perception

  5. Motion perception


Correct Option: A
Explanation:

Gestalt psychology emphasizes the importance of perceiving objects as organized wholes rather than as individual elements, focusing on the principles of perceptual organization and the tendency to perceive meaningful patterns.

The ability to perceive the relative distance and depth of objects in the environment is known as:

  1. Depth perception

  2. Motion perception

  3. Size constancy

  4. Shape constancy

  5. Color constancy


Correct Option: A
Explanation:

Depth perception allows us to perceive the relative distance and depth of objects in the environment, enabling us to navigate and interact with our surroundings effectively.

The tendency to perceive objects as having a consistent size regardless of their distance from the observer is known as:

  1. Size constancy

  2. Shape constancy

  3. Color constancy

  4. Depth perception

  5. Motion perception


Correct Option: A
Explanation:

Size constancy refers to the ability to perceive objects as having a consistent size despite changes in their distance from the observer, allowing us to recognize objects regardless of their location.

The tendency to perceive objects as having a consistent shape regardless of their orientation or viewpoint is known as:

  1. Shape constancy

  2. Size constancy

  3. Color constancy

  4. Depth perception

  5. Motion perception


Correct Option: A
Explanation:

Shape constancy allows us to perceive objects as having a consistent shape despite changes in their orientation or viewpoint, helping us to recognize objects from different perspectives.

The tendency to perceive objects as having a consistent color regardless of changes in lighting conditions is known as:

  1. Color constancy

  2. Size constancy

  3. Shape constancy

  4. Depth perception

  5. Motion perception


Correct Option: A
Explanation:

Color constancy enables us to perceive objects as having a consistent color despite changes in lighting conditions, allowing us to recognize objects under different lighting.

The ability to perceive the movement of objects in the environment is known as:

  1. Motion perception

  2. Depth perception

  3. Size constancy

  4. Shape constancy

  5. Color constancy


Correct Option: A
Explanation:

Motion perception allows us to detect and interpret the movement of objects in the environment, enabling us to track objects, avoid obstacles, and interact with moving objects effectively.

The process of combining information from different sensory modalities to create a unified perception of the environment is known as:

  1. Sensory integration

  2. Perceptual organization

  3. Depth perception

  4. Motion perception

  5. Color constancy


Correct Option: A
Explanation:

Sensory integration involves combining information from different sensory modalities, such as vision, hearing, and touch, to create a unified and coherent perception of the environment.

The tendency to perceive objects as being located in a specific position in space is known as:

  1. Spatial localization

  2. Depth perception

  3. Size constancy

  4. Shape constancy

  5. Color constancy


Correct Option: A
Explanation:

Spatial localization allows us to perceive the location of objects in space relative to our own position, enabling us to navigate and interact with our surroundings effectively.
