Understanding the Perceptual System

What is the primary role of the perceptual system?

• Decision-making based on prior knowledge

• Processing and interpreting sensory inputs

• Controlling motor responses

• Storing information in long-term memory

Which of the following is NOT a component of the perceptual system?

• Visual system

• Auditory system

• Cognitive reasoning system

• Haptic system

What does "exposure" in the perceptual process refer to?

• The act of interpreting sensory data

• The initial sensory contact with a stimulus

• The adjustment to repeated stimuli

• Focusing on specific sensory data

In the perceptual process, attention refers to:

• Ignoring irrelevant stimuli

• Focusing on a specific stimulus

• Automatically processing sensory input

• Adapting to frequent exposure

What is "interpretation" in the context of the perceptual system?

• Ignoring distractions to focus on a stimulus

• Creating meaning from sensory input

• The physical act of sensing stimuli

• Becoming insensitive to a repeated stimulus

Which sensory modality is involved in perceiving vibrations and pressure?

• Visual

• Auditory

• Haptic

• Olfactory

The phenomenon of "change blindness" occurs when:

• The brain quickly notices small changes

• Users become blind to frequent stimuli

• People fail to detect changes in their environment

• The brain creates false interpretations of stimuli

Adaptation occurs in the perceptual system when:

• Stimuli are completely ignored

• Users adjust to repeated exposure to a stimulus

• The stimulus creates a surprise response

• The sensory input is too complex to process

What role does the visual system play in the perceptual system?

• Interpreting vibrations and texture

• Processing images and spatial information

• Understanding language and speech

• Controlling motor responses

Which factor is NOT used to command user attention in interface design?

• Size

• Color

• Placement

• Adaptation
