Sensation and Perception

What are sensory receptors?

• Cells that produce sensory stimuli

• Structures that respond to nonspecific stimuli

• Specialized cells that detect and respond to motor stimuli

• Specialized cells or structures that detect and respond to specific types of sensory stimuli.

Explain the process of sensory adaptation.

• Sensory adaptation is the process by which our sensory receptors become more responsive to constant or unchanging stimuli over time.

• Sensory adaptation is the process by which our sensory receptors become completely unresponsive to any stimuli over time.

• Sensory adaptation is the process by which our sensory receptors become more sensitive to changing stimuli over time.

• Sensory adaptation is the process by which our sensory receptors become less responsive to constant or unchanging stimuli over time.

What is selective attention?

• The ability to focus on multiple stimuli simultaneously.

• The inability to focus on any stimulus or task.

• The ability to focus on irrelevant information while ignoring important stimuli.

• The ability to focus on a specific stimulus or task while ignoring other distractions or irrelevant information.

How do sensory receptors convert stimuli into neural signals?

• Inhibition

• Amplification

• Transduction

• Transmission

Discuss the role of sensory adaptation in our perception of the world.

• Sensory adaptation helps us filter out irrelevant information and maintain sensitivity to important changes in our surroundings.

• Sensory adaptation only occurs in certain individuals.

• Sensory adaptation makes us more sensitive to irrelevant information.

• Sensory adaptation has no effect on our perception of the world.

What factors influence selective attention?

• Age, gender, and ethnicity

• Salience of stimuli, personal relevance, emotional significance, novelty, and cognitive load.

• Physical attractiveness, social status, and popularity

• Weather conditions, time of day, and location

Describe the different types of sensory receptors found in the human body.

• taste receptors, smell receptors, touch receptors, sound receptors

• pressure receptors, light receptors, pain receptors, taste receptors

• heat receptors, pressure receptors, sound receptors, smell receptors

• mechanoreceptors, thermoreceptors, nociceptors, photoreceptors, and chemoreceptors

What are the advantages and disadvantages of sensory adaptation?

• The advantages of sensory adaptation include allowing us to focus on new or changing stimuli, preventing sensory overload, and conserving energy. The disadvantages include potentially missing important or dangerous stimuli and decreased sensitivity to subtle changes in the environment.

• Sensory adaptation increases sensitivity to subtle changes in the environment.

• Sensory adaptation only has disadvantages.

• Sensory adaptation has no advantages or disadvantages.

Explain the concept of inattentional blindness and its relation to selective attention.

• Inattentional blindness is the failure to notice expected stimuli due to selective attention.

• Inattentional blindness is the failure to notice unexpected stimuli due to selective attention.

• Inattentional blindness is the result of divided attention between multiple stimuli.

• Inattentional blindness is the ability to notice unexpected stimuli even with selective attention.

How does selective attention affect our ability to multitask?

• Selective attention hinders our ability to prioritize and switch between tasks, making multitasking more difficult.

• Selective attention enhances our ability to multitask by allowing us to fully concentrate on multiple tasks simultaneously.

• Selective attention has no impact on our ability to multitask.

• Selective attention helps us prioritize and switch between tasks, but it limits our ability to fully concentrate on multiple tasks simultaneously.
