Popis: | The same-different judgment was used in two experiments to investigate age-group differences in visual processing. Two targets next to fixation were presented; the tar gets on one-half of the trials were the same, and on the other half of the trials, the tar gets differed by color, shape, or color and shape (redundant). Response times were lower for redundant trials than for color-only and shape-only trials; this redundancy 10 gain was greater for older observers than for young observers. Capacity measures based on the integrated hazard functions indicated that young adults, but not older adults, experienced a slowing of processing (reduction of capacity) in the redundant condition. These capacity measures may provide a method for interpreting age-group effects in the presence of overall response-time differences. 15 |
