In Simon-type interference tasks, participants are asked to perform a 2-choice reaction on a stimulus dimension while ignoring the stimulus position.

Discusses the literature on interference as the cause of errors in second language speech. A study is reported which shows that interference by the native language is most often the factor responsible for the largest number of mistakes in grammar and vocabulary. (Author/AMH)

A study of overregularized use of verbs by two children over a period when they were 2 1/2 to 5 years of age shows overregularizations in two directions: non-causative verbs were used as causatives; and causative verbs were used non-causatively. According to terminology from logic, predicates were classified according to the number of noun-phrase…

Analysis of error patterns in a test taken by 698 Finnish university students shows errors are made in this declining order of frequency: grammar, pronunciation, vocabulary, and use. More talkative students were proportionately more proficient per utterance, and higher proficiency also correlated with sex (female) and high matriculation test…
