Which of the following best describes sensory adaptation?

• The transformation of stimulus energy into neural messages

• Diminished sensitivity as a consequence of constant stimulation

• Increased alertness from a sudden stimulus

• Detection of a weak signal under uncertain conditions

What is the term for reduced awareness of a stimulus after constant exposure?

• Difference threshold

• Sensory adaptation

• Perceptual constancy

• Signal fluctuation

Which choice correctly identifies the term: “Diminished sensitivity as a consequence of constant stimulation”?

• Sensory adaptation

• Sensory integration

• Perceptual shift

• Neural tuning

In a study, participants exposed to continuous background noise initially found it distracting but reported not noticing it after 10 minutes. This is an example of:

• Auditory masking

• Sensory adaptation

• Just noticeable difference

• Threshold variation

A subject initially detects the strong scent of cleaning products when entering a room, but after an hour, no longer notices the smell. This best represents:

• Neural fatigue

• Sensory adaptation

• Habituation

• Olfactory overload

Participants were asked to stare at a bright red circle on a screen for five minutes. Over time, their ability to detect the color weakened. Which sensory process explains this change?

• Perceptual desensitization

• Sensory adaptation

• Saturation response

• Visual recalibration

A subject listens to white noise while studying. After 30 minutes, the sound fades into the background and becomes unnoticeable. This change is best described as:

• Sensory blocking

• Sensory adaptation

• Difference threshold

• Signal filtering

Which of the following situations best applies the concept of sensory adaptation?

• Noticing the buzz of a refrigerator when entering a kitchen

• Learning to distinguish musical notes

• Becoming less aware of the feel of socks over time

• Judging the weight of objects accurately

A researcher increases the intensity of a repetitive stimulus across participants. The longer the exposure, the less they notice it. This pattern most likely demonstrates:

• Stimulus decay

• Sensory adaptation

• Differential detection

• Neural interference

What term refers to the conversion of one form of energy into another form that the brain can interpret?

• Sensory registration

• Transduction

• Perceptual interpretation

• Neural translation
