The processing of affixed words.

Two experiments are reported which suggest that affixed words are not morphologically decomposed but are processed as single units. Experiment 1 involved a lexical decision task, and it suggested that lexical access does not require decomposition. Experiment 2 involved a task designed to maximize the opportunity for decomposition, but it showed that subjects processed the test items as single units. These results are discussed in relation to o;her evidence that has been offered to support the occurrence of morphological decomposition.
