Threshold Review

Which of the following best describes the concept of "absolute threshold" in sensation?

• The minimum difference between two stimuli required for detection 50% of the time.

• The minimum stimulus energy needed to detect a particular stimulus 50% of the time.

• The maximum intensity of a stimulus that can be detected.

• The ability to detect a stimulus without conscious awareness.

What does the "difference threshold" refer to in the context of sensation?

• The smallest detectable difference between two stimuli.

• The maximum intensity of a stimulus that can be detected.

• The ability to detect a stimulus without conscious awareness.

• The minimum stimulus energy needed to detect a particular stimulus 50% of the time.

Which of the following statements is true about the "just noticeable difference" (JND)?

• It is the same as the absolute threshold.

• It is the smallest change in stimulus intensity that can be detected.

• It refers to the maximum intensity of a stimulus that can be detected.

• It is unrelated to the difference threshold.

Signal Detection Theory is used to explain which of the following phenomena?

• The ability to detect a stimulus without conscious awareness.

• The process of distinguishing between signal and noise in sensory detection.

• The minimum stimulus energy needed to detect a particular stimulus 50% of the time.

• The smallest detectable difference between two stimuli.

Which of the following best describes a "subliminal message"?

• A message that is consciously perceived and easily understood.

• A message that is below the absolute threshold for conscious awareness.

• A message that is above the absolute threshold for conscious awareness.

• A message that is irrelevant to the context.

Which of the following is an example of a subliminal message?

• A billboard advertisement that is clearly visible.

• A whispered message that is easily heard.

• A brief image flashed on a screen too quickly to be consciously perceived.

• A loud announcement over a public address system.

Which of the following best explains the concept of 'sensory adaptation'?

• The minimum stimulus energy needed to detect a particular stimulus 50% of the time.

• The process by which our sensory receptors become less sensitive to constant stimuli.

• The smallest detectable difference between two stimuli.

• The ability to detect a stimulus without conscious awareness.

Which is an example of sensory adaptation?

• those who live in an area with continuous traffic, they no longer hear the noise of the traffic.

• the ability to hear a crying baby even in the middle of a tornado

• telling the difference between a blue sheet and a black sheet

• hearing a sound that no one else can hear when its been playing for a long time
