چکیده
The concurrent-memory-load technique identifies attention demands with interactions between reaction-time-task parameters and the size of the load on memory. Three experiments are reported in which a multiple-choice, reaction time task involving two, four, and eig-ht stimulus-response (S-R) alternatives was performed alone and in the retention interval of a short-termmemory task involving ordered recall of eight digits. In Experiment 1, assignment of stimulus letters to response buttons (S-R mapping) was consistent for 6 days but varied on the seventh. Memory load and number of alternatives interacted early in practice, but the interaction diminished over days, and the effects were additive on Day 6. When the S-R mapping changed on Day 7, the interaction returned. In Experiment 2, S-R mapping varied daily for 6 days, and the interaction remained stable throughout practice. In Experiment 3, S-R mapping was consistent for 6 days and varied on the seventh, but the memory task was not introduced until Days 6 and 7. The interaction between memory load and number of alternatives was stronger on Day 7, after the mapping had changed, than it was on Day 6, after practice with consistent mapping. The discussion focuses on the validity of the concurrent-memory-load technique and its relation to another method for measuring attention and automaticity, and on the importance of practice with consistent mapping and practice with dual-task conditions in the development of automaticity.

Experience, context, and the visual perception of human movement.
Why are human observers particularly sensitive to human movement? Seven experiments examined the roles of visual experience and motor processes in human movement perception by comparing visual sensitivities to point-light displays of familiar, unusual, and impossible gaits across gait-speed and identity discrimination tasks. In both tasks, visual sensitivity to physically possible gaits was sup...
