Abstract:
Prior studies exploring the contribution of amplitude envelope information to spoken word recognition are mixed with regard to the question of whether amplitude envelope alone, without spectral detail, can aid isolated word recognition. Three experiments show that the amplitude envelope will aid word identification only if two conditions are met: (1) It is not the only information available to the listener and (2) lexical ambiguity is not present. Implications for lexical processing are discussed.

Interference: Path Lengths
Two special sources may be considered when they are in phase. This can be easily achieved by feeding the two sources from the same source. An example would be synchronizing the two speakers by feeding them with the same source, such as the sound waves produced by a tuning fork. This setup ensures that the two sources have the same frequency and are...

Higher Mental Functions of the Brain: Language
Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...
Perceiving Loudness, Pitch, and Location
Place theory, or place coding, suggests that different pitches are heard because various sound waves activate specific locations along the cochlea's basilar membrane. The brain determines the pitch of a sound by...
