This paper reviews some recent developments in the area of short-term memory. The methodological innovations include the distractor technique and the probe technique. The main empirical phenomena discussed are recency effects, input and output interference, the length—difficulty relationship, inter-item interference, proactive interference effects, the distribution of practice interaction, associative symmetry, modality effect, acoustic confusions, and transpositions. A ‘modal model’ is presented which attempts to synthesize some recent theoretical conceptions; the components include sensory, short-term and long-term stores with three different forgetting mechanisms (decay, displacement and interference, respectively).
