• In a visual word naming study, older adults exhibited longer naming latencies than younger adults
Caplan, Dede, Waters, Michaud, & Tripodis, 2011
• Age associated with longer online reading times at points of greater cognitive demand
Wingfield, Peelle, & Grossman, 2003
• Older adults are less able to comprehend speeded speech
Dagerman, MacDonald, & Harm, 2006
• Older adults less able to rapidly integrate context to resolve ambiguities (Dagerman, MacDonald, & Harm, 2006) – OK in off-line task, bad in online task
Madden, 1988
• Differential slowing of feature extraction in visual word recognition tasks is mediated by increased use of semantic information
Tun, Wingfield, Stine, & Mecsas, 1992
• In a task of immediate recall of spoken sentences at varying rate, recall for older adults was differentially depressed at very fast speech rates. However, the age*speech rate interaction was not exacerbated in the dual-task condition (in which the secondary task was picture recognition), suggesting that age-related deficits in recall were related to the speed at which processing components underlying memory for speech are completed, but not due to attentional resource deficits
Madden, 1992
• Age-effects in a visual word recognition task were attenuated by statistically controlling for individual differences in a task-independent measure of processing speed
Caplan, Dede, Waters, Michaud, & Tripodis, 2011
• Although there were negative correlations between processing speed and working memory capacity and age, there were no correlations between speed/WM and reading times, and the effect of age on differences in online reading time remained significant after partialing out the effects of speed/WM
Finkel, Reynolds, McArdle, & Pederson 2007
• In an analysis of data from a longitudinal study, processing speed did not indicate age-related changes in verbal (i.e., information, analogies) abilities
