   imagine a mother in the grocery store looking for her child. she calls out the childs name and waits for them to answer, then walks in the direction of the sound to find where they are. what perceptual hearing task is being illustrated in this scenario?
   place theory
   sensory adaptation
   frequency theory
   auditory localization
   what substance are nontasters insensitive to?
   lemon juice
   ptc
   glutamate
   salt

2. Brief Explanations
   1. For the first question: Auditory localization is the ability to identify the direction and location of a sound source, which matches the mother's action of walking toward her child's voice. Place and frequency theories explain how we perceive pitch, while sensory adaptation refers to reduced response to constant stimuli.
   2. For the second question: Nontasters are a group of people with a genetic insensitivity to the bitter taste of phenylthiocarbamide (PTC), while they can perceive the other listed substances normally.
3. Final answer
   1. Auditory localization
   2. PTC
