title: Input, retention, and output factors affecting adult age differences in visuospatial short-term memory.
abstract: OBJECTIVE
  The sources of age differences in short-term memory for spatial locations were explored in 2 experiments that examined factors related to input, to maintenance, and to output.
  
  
  METHODS
  In each experiment, 4 dots were presented briefly, followed after a retention interval by a probe dot, which was judged to either match or not match one of the 4 memory-set dots.
  
  
  CONCLUSIONS
  Results showed that poorer performance by older adults could be attributed independently to reduced visual acuity, to less effective use of rehearsal strategies, and to differences in response biases.
