We introduce and empirically evaluate the strategy-affordance hypothesis, which holds that individual differences in strategy use will mediate the relationship between performance on a working memory (WM) span task and another cognitive task only when the same strategies are afforded by both tasks. One-hundred and forty eight participants completed basic memory tasks and verbal span tasks that ...

Assessments of cognitive and verbal functions are widely used as screening tests to detect early dementia. This study developed an early dementia prediction model for Korean elderly based on random forest algorithm and compared its results and precision with those of logistic regression model and decision tree model. Subjects of the study were 418 elderly (135 males and 283 females) over the ag...

In this study, the new standard computerized version of the reading span test was used to investigate the development of verbal working memory over age. A significant higher reading span and faster reaction times were expected for the young adults compared to the old adults, based on the processing resource theory (Just & Carpenter, 1992) and the theory of cognitive aging (Salthouse, 1994, 1996...

It has recently been suggested that speakers vary in the amount of speech planning and that the scope of planning is influenced by taskand speaker specific constraints. To test this, an experiment is presented examining the effects of linguistic structure and working memory on speech planning, as evidenced in pause duration and F0 peaks. Twenty speakers of German performed two tasks. In the fir...

Results: Before age 3 years, the children in this study watched an average of 2.2 hours per day; at ages 3 to 5 years, the daily average was 3.3 hours. Adjusted for the covariates mentioned earlier, each hour of average daily television viewing before age 3 years was associated with deleterious effects on the Peabody Individual Achievement Test Reading Recognition Scale of 0.31 points (95% conf...

This study investigated the contribution of verbal working memory to the oral and written story production of deaf children. Participants were 29 severely to profoundly deaf children aged 8-13 years and 29 hearing controls, matched for grade level. The children narrated a picture story orally and in writing and performed a reading comprehension test, the Wechsler Intelligence Scale for Children...
