在两个实验中,年轻人和老年人被提出了简单的乘法问题(例如,4× 7= 28和5× 3= 10),他们的时间,正确或错误的判断。在心算基础研究中获得的所有典型效应都得到了,即反应时间(a)随着问题的大小而增加,(B)在答案与正确值偏差很小的情况下减慢,(c)在出现相关(例如,7× 4= 21)与不相关(例如,7 × 4= 18)答案时减慢。老年人的判断速度较慢。最重要的是,年龄与问题大小或分裂大小没有显着的相互作用。作者认为,老年人的中枢过程,如记忆提取和决策,并没有表现出典型的年龄缺陷,因为这些过程在简单算术中的熟练性质。
In 2 experiments, younger and older adults were presented with simple multiplication problems (eg, 4× 7= 28 and 5× 3= 10) for their timed, true or false judgments. All of the effects typically obtained in basic research on mental arithmetic were obtained, that is, reaction time (a) increased with the size of the problem,(b) was slowed for answers deviating only a small amount from the correct value, and (c) was slowed when related (eg, 7× 4= 21) versus unrelated (eg, 7× 4= 18) answers were presented. Older adults were slower in their judgments. Most important, age did not interact significantly with problem size or split size. The authors suggest that elderly adults' central processes, such as memory retrieval and decision making, did not demonstrate the typical age deficit because of the skilled nature of these processes in simple arithmetic.
