Exploring Sensation and Perception Concepts

What is the process by which sensory receptors convert stimulus energies into neural impulses?

• Sensation

• Transduction

• Perception

• Adaptation

Explain how Weber’s Law applies to the difference threshold in sensory perception.

• It states that the difference threshold is a constant amount.

• It states that the difference threshold is a constant proportion of the original stimulus.

• It states that the difference threshold varies randomly.

• It states that the difference threshold is unrelated to the original stimulus.

Which of the following best describes the concept of selective attention?

• The ability to focus on a single stimulus while ignoring others.

• The ability to detect faint stimuli.

• The ability to adapt to constant stimuli.

• The ability to perceive depth.

How does Signal Detection Theory differ from the concept of absolute threshold?

• It considers only the intensity of the stimulus.

• It accounts for both the intensity of the stimulus and the decision-making process of the observer.

• It ignores the observer's decision-making process.

• It is unrelated to stimulus detection.

What is the primary focus of Gestalt Principles in perception?

• The individual elements of a stimulus.

• The whole form or configuration of a stimulus.

• The depth cues of a stimulus.

• The sensory adaptation to a stimulus.

Describe how binocular cues contribute to depth perception.

• They rely on the difference in images between the two eyes.

• They rely on the size of the object.

• They rely on the texture of the object.

• They rely on the color of the object.

Which of the following is an example of top-down processing?

• Recognizing a face based on its individual features.

• Understanding a sentence based on prior knowledge of language.

• Detecting a sound based on its frequency.

• Feeling a texture based on its roughness.

How does perceptual constancy help us maintain a stable perception of the world?

• By allowing us to perceive objects as unchanging despite changes in sensory input.

• By allowing us to perceive objects as changing with every new sensory input.

• By allowing us to ignore all sensory input.

• By allowing us to focus only on moving objects.

What role does schema play in perception?

• It helps in the detection of faint stimuli.

• It organizes and interprets information based on past experiences.

• It adapts to constant stimuli.

• It focuses on a single stimulus.

Explain the function of the auditory system in sensory processing.

• It processes visual information.

• It processes sound waves into neural signals.

• It processes taste sensations.

• It processes smell.
