Strategy selection and aging: impact of item concreteness in paired-associate task

The aim of this study was to examine the effect of aging on strategy selection in a paired-associate word task. Twenty-eight younger adults (mean age = 20.68 years) and 28 older adults (mean age = 68.46 years) studied 39 pairs of concrete, middle and abstract words. The concreteness level was manipulated in order to modify the benefit of imagery and sentence strategies in relation to task characteristics. The results showed an age difference in strategy selection in relation to concreteness level. Older adults showed less adaptive strategy selection for the imagery strategy but not for the sentence strategy. Change in strategy selection did not seem to be explained by better efficiency of sentence than imagery, so this study suggests a partial reduction of strategy adaptivity during aging.     

Pediatric traumatic brain injury: Language outcomes and their relationship to the arcuate fasciculus

Pediatric traumatic brain injury (TBI) may result in long-lasting language impairments alongside dysarthria, a motor-speech disorder. Whether this co-morbidity is due to the functional links between speech and language networks, or to widespread damage affecting both motor and language tracts, remains unknown.
