Question

BlackTom AI · Accepted Answer

In the High Amplitude Sucking (HAS) paradigm, researchers are interested in how infants' sucking behavior changes as they hear different sounds. 
Option 1: They determine the amplitude of infants' sucking while sound is played. While HAS does involve the infant's sucking behavior, the classic measure is not simply the raw amplitude, but how the rate or pattern of sucking changes in response to auditory stimuli. This makes the statement partially inaccurate or overly specific about amplitude as the sole metric. 
Option 2: They observe whether infants stop sucking at all when a sound is played. This description is not representative of HAS, which tracks changes in sucking behavior rather than a binary cessation of sucking in response to sounds. 
Option 3: They record changes in how much infants suck on a pacifier as they listen to sounds. This captures the core idea of HAS: infants modulate their sucking behavior (often their rate or amount) depending on the auditory stimulus, providing a proxy for perceptual discrimination. 
Option 4: They measure the infants' facial expressions as they suck in response to a sound. Facial expressions are not the primary measurement in HAS; the method relies on sucking behavior rather than facial affect to infer perceptual processing. 
Overall, the design centers on linking auditory input to changes in sucking, making option 3 the best match for the HAS procedure.
