constraint based model sentence processing model/theory is supported by evidence showing integration of different types of cues .
Humans use two important cues to help determine where a sound is coming from. These cues are: (1) which ear the sound hits first (known as interaural time differences), and (2) how loud the sound is when it reaches each ear (known as interaural intensity differences)
At 1-2 years, your child will learn to use and understand more words and more types of words. At first they'll understand and say mostly nouns – for example, 'dog' and 'bus'. Eventually they'll understand and say a few verbs – for example, 'eat' and 'run'
According to the duplex theory of sound localization, sounds are localized through a combination of interaural time differences (ITD) and interaural level differences (ILD).
