Question

when regina put her socks on in the morning they felt tight and uncomfortable. not having enough time to change into new socks, regina left for school. although the socks had bothered her in the morning, by lunchtime, regina noticed that she had forgotten about the socks for the past few hours. what concept can explain reginas experience?
sensory adaptation
difference threshold
bottom-up processing
top-down processing

16 multiple choice 1 point
the wavelength of a soundwave corresponds to which of the following perceptions?
brightness
color
volume
pitch

Explanation:

Analyze Regina's experience with her tight socks

Regina initially notices the tight sensation of her socks, but over time, her sensory receptors stop responding to this constant, unchanging stimulus. This reduction in sensitivity to a constant stimulus is known as sensory adaptation. The concept of Difference Threshold (the minimum difference between two stimuli required for detection 50% of the time) does not apply here because there is no comparison between two changing stimuli.

Identify the correct option for the first question

Since Regina's sensory receptors adapted to the constant pressure of the socks, she forgot about them. This directly illustrates sensory adaptation. Therefore, the correct option is "sensory adaptation".

Analyze the properties of sound waves

We need to determine what perception corresponds to the wavelength of a sound wave. Using our understanding of Sound Wave Properties, we know that the frequency or wavelength of a sound wave determines its frequency of vibration, which we perceive as pitch (how high or low a sound is).

Identify the correct option for the second question

Wavelength (or frequency) of a sound wave corresponds to pitch. Brightness and color are visual perceptions related to light waves, while volume corresponds to the amplitude of a sound wave. Therefore, the correct option is "pitch".

Answer:

Question 1

• sensory adaptation (Correct answer)
• difference threshold
• bottom-up processing
• top-down processing

Question 2

• brightness
• color
• volume
• pitch (Correct answer)
