Fill in the Blanks Information Processing (2)Online version Information Processing (2) by Danielle Freitas 1 qualitative backsliding Restructuring progress restructuring Sometimes changes in language behaviour do not seem to be explainable in terms of a gradual build - up of fluency through practice . These changes have been described in terms of ( McLaughlin 1990 ) . They seem to be based on some change in the learner's knowledge . may account for what appear to be bursts of , when learners suddenly seem to ? put it all together' , even though they have not had any new instruction or apparently relevant exposure to the language . It may also explain apparent , when a systematic aspect of a learner's language incorporates too much or incorporates the wrong things . For example , when a learner finally masters the use of the regular - ed ending to show past tense , irregular verbs that had previously been used correctly may be affected . Such overgeneralization errors are not based on practice of those specific items but rather on their integration into a general pattern .
