Improving Everyday Functioning in the Old-Old with Working Memory Training.

OBJECTIVE: The aim of this study was to assess gains related to working memory (WM) training, in the short and long term (9 months after the training), in abilities required in everyday life, and in cognitive measures in old-old adults (aged ≥ 75 years). METHODS: Thirty-two community-dwelling older adults (aged 75-85 years) were randomly assigned to a training or an active control group. In addition to testing for any specific gains in a WM task similar to the one used in the training (criterion task), we sought transfer effects to: 1) abilities involved in everyday life using objective performance-based tasks (the Everyday Problem Test [EPT] and the Timed Instrumental Activities of Daily Living [TIADL] scale; 2) tasks demanding the comprehension and recall of spatial information and pairing names with faces; and 3) a measure of inhibitory control, that is, recall errors (intrusion errors). RESULTS: Only the trained group showed specific gains in the criterion task, and in the TIADL in the short term. At follow-up, the trained group maintained gains in the criterion task, and showed transfer effects to everyday problem-solving (in the EPT), and in constructing spatial representations of an environment. The trained group also improved in a cognitive inhibition measure (intrusion errors) at follow-up. No such improvements were seen in the active control group. CONCLUSION: WM training may be a valid way to help old-old adults preserve at least some abilities related to everyday functioning.

Benefits of Well-Being Training in Healthy Older Adults.

INTRODUCTION: Several studies have shown that psychological well-being (PWB) can be promoted through positive psychological interventions (PPIs). Although these interventions have shown promising results in clinical settings, only a few studies have investigated their effectiveness in older adults, and they have rarely considered an active control group. In addition, generalisation effects of the PWB training to quality of life (QoL) and to untrained cognitive abilities have never been considered. OBJECTIVE: In this study, we evaluated the effectiveness of a six-session PWB intervention aiming specifically to improve PWB, and sought any transfer effects on an aspect related to PWB, QoL. Transfer effects on a high-level cognitive process, working memory (WM), were also investigated. METHODS: Thirty-two older adults (61-82 years old) volunteered to take part in the study and were randomly assigned to either a training group or an active control group. RESULTS: Only the trained group, once controlled for variability, reported larger gains in PWB and in WM performance after the training. CONCLUSIONS: This pilot study suggests that PWB training can be effective in older adults, with a positive generalisation effect on cognition (WM). The discussion focuses on the need to develop PPIs tailored to older adults' needs and resources.

Performance-based everyday functional competence measures across the adult lifespan: the role of cognitive abilities.

BACKGROUND: The effects of age on the ability to manage everyday functioning, crucial to ensure a healthy aging process, have been rarely examined and when, self-report measures have been used. The aim of the present study was to examine age effects across the adult lifespan in everyday functioning with two performance-based measures: the Everyday Problems Test (EPT), and the Timed Instrumental Activities of Daily Living (TIADL) tasks. The role of some crucial cognitive abilities, i.e. working memory (WM), processing speed, reasoning, vocabulary, and text comprehension in the EPT and the TIADL were also assessed to see whether or not they have a similar influence (and to what extent) in accounting for age-related effects in these two performance-based measures. METHOD: Two hundred and seventy-six healthy participants, from 40 to 89 years of age were presented with the EPT, the TIADL, as well as WM, processing speed, reasoning, text comprehension, and vocabulary tasks. RESULTS: Path models indicated an indirect effect of age and education on the EPT, which was mediated by all the cognitive variables considered, with WM and reasoning being the strongest predictors of performance. An indirect quadratic effect of age, but not of education, was found on the TIADL score, and an accelerated decline in processing speed mediated the relationship between age and the TIADL score. CONCLUSION: This study revealed age-related effects in performance-based measures, which are mediated by different cognitive abilities depending on the measure considered. The findings highlight the importance of assessing everyday functioning even in healthy older adults.

Benefits in tasks related to everyday life competences after a working memory training in older adults.

OBJECTIVE: The impact of working memory (WM) training on everyday life functioning has rarely been examined, and it is not clear whether WM training gains are transferred to reasoning abilities. The aim of this study was to assess the efficacy of a verbal WM training in older adults, in terms of specific gains and transfer effects to everyday life and reasoning abilities. METHOD: Thirty-six community dwelling older adults (from 65 to 75 years of age) were randomly assigned to a training or an active control group. The specific gains in a WM task similar to the one trained were assessed. Transfer effects to everyday life and reasoning abilities were also examined using (i) objective performance-based tasks (the Everyday Problem Test and the Timed Instrumental Activities of Daily Living Scale) and (ii) the Cattell test and Raven's Standard Progressive Matrices, respectively. RESULTS: Only the trained group showed specific benefits and transfer effects to one of the everyday abilities measures (the Everyday Problem Test) and in the two reasoning tasks. CONCLUSION: These results suggest that WM training can positively impact cognitive functioning and, more importantly, older adults' abilities in everyday living.

Benefits of training visuospatial working memory in young-old and old-old.

The purpose of the present study was to test the efficacy of a visuospatial working memory (WM) training in terms of its transfer effects and maintenance effects, in the young-old and old-old. Forty young-old and 40 old-old adults took part in the study. Twenty participants in each age group received training with a visuospatial WM task, whereas the others served as active controls and completed alternative activities. Training benefits were examined, considering (a) the specific training-related gains in a visuospatial WM task (criterion); and (b) the transfer effects on measures of verbal WM, visuospatial short-term memory, inhibition, processing speed, and reasoning. Maintenance of training benefits was also assessed after 8 months. Results showed that the trained groups (both young-old and old-old), but not the control groups, performed better in the WM measures and preserved these gains after 8 months. Some transfer effects were found, but only in the young-old-trained participants, and they were not maintained at the follow-up. These results are discussed in terms of the efficacy of WM training for older adults when a visuospatial modality is used.
