认知技能的获得通常依赖于两个过程中的一个(或组合)、算法的执行和问题实例的检索。本研究考察了年龄和问题实例的重复对两组连续呈现的字母算术问题解决方案的产生和验证的影响。由幂函数拟合得到的参数的分析表明，年龄差异在改善广度、学习速度和渐近线方面有利于年轻人。对于这两个年龄段，重复对第一组响应时间的有益影响归因于算法加速和实例检索，而第二组响应时间速度的提高主要归因于项目检索。(智力信息数据库记录(C)2016 APA，保留所有权利)
The acquisition of cognitive skills often depends on 1 of (or a combination of) 2 processes, the execution of an algorithm, and the retrieval of problem instances. This study examined the effects of age and repetition of problem instances on the production and verification of solutions to 2 serially presented sets of alphabet arithmetic problems. Analyses of the parameters derived from power-function fits for individuals revealed age differences favoring young adults in improvement span, learning rate, and asymptote. For both age groups, the beneficial effects of repetitions on 1st-set response times were attributable to algorithmic speedup and to the retrieval of instances, whereas improvements in the speed of 2nd-set response times were attributable primarily to item retrieval.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
