Understanding Sensation and Perception

What is the process by which our sensory receptors and nervous system receive and represent stimulus energies from our environment?

• Perception

• Sensation

• Cognition

• Interpretation

Which of the following best describes the process of organizing and interpreting sensory information, enabling us to recognize meaningful objects and events?

• Sensation

• Perception

• Adaptation

• Transduction

The minimum stimulus energy needed to detect a particular stimulus 50% of the time is known as:

• Difference threshold

• Absolute threshold

• Sensory adaptation

• Signal detection

Which theory explains how we detect the presence of a faint stimulus (signal) amid background noise (other stimulation)?

• Gate-control theory

• Signal detection theory

• Opponent-process theory

• Place theory

The diminishing sensitivity to an unchanging stimulus is referred to as:

• Sensory adaptation

• Perceptual set

• Bottom-up processing

• Top-down processing
