1.2.1 Sensation and Perception

• What is sensation defined as?

  Receiving sensory information
• What is perception defined as?

  Interpreting sensory information
• Sensation is a passive process, while perception is an active process.


  True
• Sensation converts physical stimuli into neural signals, while perception interprets these signals.


  True
• Sensation involves the detection of physical stimuli like light, sound, taste, smell, and pressure
• Perception involves higher-level cognitive processes to make sense of the world
• Sensation occurs in the sense organs, while perception occurs in the brain
• Which sensory receptors detect light in the eyes?

  Visual receptors
• Match the sensory receptor with its function:

  Visual receptors ↔️ Detect light

  Auditory receptors ↔️ Detect sound waves

  Olfactory receptors ↔️ Detect odors

  Gustatory receptors ↔️ Detect tastes

  Somatosensory receptors ↔️ Detect touch, pressure, etc.
• Visual receptors detect sound waves.

  False
• Sensory receptors are responsible for the initial perception of physical stimuli.

  False
• During transduction, sensory receptors convert physical stimuli into an electrical signal called an action potential
• Perception involves higher-level cognitive processes that allow us to make sense of and understand the world.
• Perception is a passive process that depends on external stimuli only.

  False
• Visual receptors are located in the retina of the eyes.


  True
• Which sensory receptors detect touch, pressure, and temperature?

  Somatosensory receptors
• Sense organs such as the eyes, ears, nose, and skin detect physical stimuli and convert them into neural signals.


  True
• Match the process with its description:

  Sensation ↔️ Receiving sensory information

  Perception ↔️ Interpreting sensory information
• What is an example of the difference between sensation and perception?

  Hearing a sound vs recognizing it
• Auditory receptors in the ears detect sound waves and convert them into neural signals.
• What type of stimuli do gustatory receptors detect?

  Chemical stimuli (tastes)
• Where are auditory receptors located?

  Ears
• What are the three main steps in converting sensory stimuli into neural signals?

  Stimulation, transduction, conduction
• What is the primary function of sensation?

  Receiving sensory information
• Match the process with its description:

  Sensation ↔️ Receives sensory information

  Perception ↔️ Interprets and organizes sensory information
• The perception of a bird chirping after hearing the sound is an example of perception
• What type of stimulus do auditory receptors detect?

  Sound waves
• Which physical stimulus is detected by visual receptors?

  Light
• What type of stimulus do gustatory receptors respond to?

  Chemical stimuli (tastes)
• Somatosensory receptors detect touch, pressure, temperature, and pain
• Olfactory receptors detect chemical stimuli in the form of odors
• Steps in converting sensory stimuli into neural signals:

  1️⃣ Stimulation

  2️⃣ Transduction

  3️⃣ Conduction
• Sensation is an active process that occurs in the brain.

  False
• Where does perception occur in the body?

  Brain
• Which sensory receptors are responsible for detecting light?

  Visual receptors
• Auditory receptors are found in the cochlea of the ears
• Where are auditory receptors located in the ear?

  Cochlea
• Somatosensory receptors detect touch, pressure, temperature, and pain
• Stimulation involves the activation of sensory receptors by a physical stimulus.

  True
• Order the steps involved in converting sensory stimuli into neural signals:

  1️⃣ Stimulation

  2️⃣ Transduction

  3️⃣ Conduction
