“…This is because although there are substantial age differences in contextual=episodic memory, there is little evidence of appreciable age deficits in semantic retrieval (e.g., Allen et al, 2004;Light, 1991;Spaniol, Madden, & Voss, 2006). Indeed, this age-related sparing for semantic retrieval appears to hold for visual word recognition (Allen et al, 1993), semantic priming (Laver, 2009), and fact 268 P. A. Allen et al retrieval from mental arithmetic (Allen, Bucur, et al, 2005;Arnaud, Lemaire, Allen, & Michel, 2008;Geary, Frensch, & Wiley, 1993). Unlike word frequency effects, which are relatively consistent across adult age, lexical decision case-mixing effects are often larger for older adults than for younger adults (Allen et al, 1993;Allen, Smith, et al, 2002).…”

It is presently unclear as to why older adults take longer than younger adults to recognize visually presented words. To examine this issue in more detail, the authors conducted two word-naming studies (Experiment 1: 20 older adults and 20 younger adults; Experiment 2: 60 older adults and 60 younger adults) to determine the relative effects of orthographic encoding (case type), lexical access (word frequency), and phonological regularity (regular vs. irregular phonology). The hypothesis was that older adults attempt to compensate for sensory and motor slowing by using progressively larger perceptual units (holistic encoding). However, if forced to use smaller perceptual units (e.g., by using mixed-case presentation), it was predicted that older adults would be particularly challenged. Older adults did show larger case-mixing effects than younger adults (suggesting that older adults' performances were especially poor when they were forced to use smaller perceptual units), but there were no age differences in word frequency or phonological regularity even though both age groups showed main effects for these variables. These results suggest that lexical access skill remains stable in the addressed (orthographic/semantic) and assembled (phonological) routes over the life span, but that older adults slow down in recognizing words because it takes them longer to normalize (perceptually "clean up") noisier sensory information.

“…Interestingly, such a dissociation between 0 and 1 problems has already be documented in the domain of multiplication by Allen et al (2005) who showed that older adults make more errors than younger ones for x 0 problems but not for x 1 problems. The authors concluded that rule retrieval was impaired in older adults and therefore suggested that x 1 problems were processed exactly as other multiplication involving operands different from 0.…”

Younger and older adults performed an inequality verification task (7+6 < 15, Yes/No?) in a control condition and in a dual-task condition where they simultaneously performed an executive-component task. Arithmetic-problem characteristics were manipulated in order to test strategy selection (i.e., choice of appropriate strategies in order to improve performance) and strategy execution (i.e., performance of the cognitive processes involved in each strategy). Results revealed that strategy selection changes with age: Older adults mainly selected one type of strategies in contrast to younger adults who used several types of strategies. These age-related changes were similar in the control and dual-task conditions. Strategy execution also changed with age, as shown by larger age-related differences on hardest problems. These age-related changes were larger in the dual-task condition, compared to the control condition. This impact of executive components as mediator of age-related changes depended on general age-related slowing. We discuss these findings in order to further understand the effects of age on arithmetic performance.
