An experiment is conducted in which a baby listens to speech sounds while sucking on a pacifier. The sucking rate is recorded as a measure of interest. This is an example of:
A) the preference method
B) the head-turning technique
C) classical conditioning
D) the high-amplitude sucking procedure

Question

Quizplus · Accepted Answer

The high-amplitude sucking procedure is a method used to study infant perception and cognition. The sucking rate is measured as an indicator of the baby's interest or attention to the stimuli presented (in this case, speech sounds). This method has been used to study different aspects of infant perception, such as speech perception, facial recognition, and memory. Choice A (the preference method) involves presenting two stimuli and recording which one the baby prefers, while choice B (the head-turning technique) involves measuring the baby's head movements in response to sounds. Choice C (classical conditioning) involves pairing a conditioned stimulus (e.g., a tone) with an unconditioned stimulus (e.g., food) to elicit a conditioned response (e.g., salivation) in the baby.
