- Abstract
- Over a lifespan, age affects the efficiency of short-term memory. However, the vast majority of studies employ verbal material. Therefore, in the present study. nonverbal, visuospatial material (patterns) was used. In addition. the best procedure for investigating nonverbal short-term memory is as yet unclear. Therefore, the present study compared three different procedures (simultaneous presentation of the material vs. two versions of a sequential presentation). In Experiment 1, a group of young adults and a group of elderly subjects was enrolled for the three kinds of assessment. It showed an effect of aging which was similar across the three procedures. In Experiment 2, six age groups (from 18 to 80 years old) were submitted to one of the procedures of Expt.1, in order to search for linear trends vs, a qualitative gap over the lifespan. A linear effect of age was observed. It thus appears that age affects the visuospatial component of short-term memory, and that this effect is progressive and linear. The kind of assessment was also seen to be irrelevant, and thus the clinical evaluation can be made using the simplest and shortest procedure (namely, simultaneous presentation).
