Kay, Lesser, and Coltheart's (1992) PALPA Transcoding Model: This model generally follows the format of Ellis and Young (1988), but with an additional input route (top centre), recognising that the semantic system can be accessed by perceiving objects per se as well as by their spoken or written names. The model forms part of a clinical assessment test battery designed for uses by Speech and Language Therapists. It is expressly "a psycholinguistic approach to the interpretation of processes concerned with the recognition, comprehension, and production of spoken and written words and sentences. The approach is based on the assumption that the mind's language system is organised in separate modules of processing, and that these can be impaired selectively by brain damage. PALPA aims to provide information about the integrity of these modules ....." (Kay, Lesser, and Coltheart, 1992:2).
