Memory for serial order: A network model of the phonological loop and its timing

摘要: A connectionist model of human short-term memory is presented that extends the "phonological loop" (A. D. Baddeley, 1986) to encompass serial order and learning. Psychological neuropsychological data motivate separate layers lexical, timing, input output phonemic information. Connection weights between show Hebbian learning decay over short long time scales. At recall, timing signal rerun, information feeds back from input, lexical nodes compete be selected. The selected node then receives decaying inhibition. provides an explanatory mechanism for phonological loop effects position, presentation modality, lexicality, grouping, Hebb repetition. It makes new psychological predictions a starting point understanding role in vocabulary acquisition interpreting functional neuroimaging.
