>> Acquisition and Evolution of Phonological Systems
>>
>> In the late 19th century, the Neogrammarians thought that a sound  change 
>> affect all lexical items simultaneously when their phonetic  environments 
>> are the same (e.g. Osthoff and Brugmann, 1878). On the  contrary, in the 
>> late 60s, Wang proposed that sound change is  initiated by a single word 
>> or a small group of words and then  spreads to the other words with a 
>> similar phonological environment,  namely lexical diffusion (1969), based 
>> on the observation that  different sound changes can happen even if the 
>> phonological  conditions are similar for the words or morphemes. The 
>> issue is  still controversial because various empirical studies provide 
>> evidence for both hypotheses (see Labov, 1994).
>> A dynamic computational model linking up the cognitive- developmental 
>> properties of the human beings (“local” mechanisms)  and the transition 
>> patterns of sound changes (“global” phenomena)  was built, in order to 
>> seek for possible solutions to resolve the  preceding controversial 
>> issue. In the simulation results of the  model, two opposing transition 
>> patterns can be found under  different conditions. During a shift without 
>> fusion of sounds, the  pronunciations of the lexical items change 
>> regularly as described  in the Neogrammarian hypothesis; during a merger, 
>> the spoken forms  display at the beginning a regular pattern as in a 
>> shift. Then the  changing pattern becomes irregular lexically as 
>> described in  lexical diffusion when the two perceptual categories are 
>> fusing  together. These conditions are primarily matched with the 
>> empirical  data reported in the literature. Besides, the simulation 
>> results  also support the existence of another controversial phenomenon, 
>> near-merger (Labov, 1994): individual speakers in the population  cannot 
>> perceptually distinguish two sounds but can produce them  differently.
