Anxiety in foreign language courses has been conceptualized as occurring at each of three stages of input, processing, and output. Specifically, input anxiety refers to the learner's apprehension when receiving information in the foreign language; processing anxiety refers to the apprehension experienced by learners when learning and thinking in the foreign language; and output anxiety refers to the apprehension experienced when speaking or writing in the foreign language. The present purpose was to investigate the relationship between achievement and anxiety at each of these three stages of learning a foreign language. Participants were 224 college students from a variety of disciplinary backgrounds, enrolled in Spanish, French, or German classes. Small but significant negative associations were found between achievement in the foreign language and scores on the Input Scale, the Processing Scale, and the Output Scale. These indicate educators should consider more than just the output stage of learning in foreign language classes.
