Abstract There is an increasing interest in using touch-screen devices to conduct cognitive training and collect measurements of cognitive performance. However, older adults often have concerns such as anxiety about using these systems and poor comprehension of language instructions (Czaja & Lee, 2007). Given that Singapore is a multilingual society, we examined the deployment of an age-friendly multi-modal touch-screen platform (a game-based application on a tablet) in a cognitive intervention research. After modification of the platform to include features such as simplified instructions, multi-level prompts with a local accent, and four different instructional languages (including local dialects), participants were less reliant on the researchers and reported fewer difficulties in comprehending the instructions. The integrity and reliability of the data collected improved as a result. In sum, multilingual age-friendly touch-screen platform can be a novel yet effective method to study cognitive interventions in the Asian older adult populations.

One of the most important determinants of successful aging is cognitive ability. Although cognitive decline is a well-documented phenomenon characteristic of aging, it is acknowledged that aging can also be related to cognitive neuroplasticity that allows one to compensate the decline and adapt to it. Cognitive neuroplasticity may be spontaneous or induced by external influences. An example of the former is compensatory brain activity in older adults, and the latter – improvement in cognitive functioning under the influence of cognitive training. Both the compensatory brain activity of older adults and the effectiveness of cognitive training in this age group have already been extensively studied. However, it has not yet been examined whether they can be linked. The article indicates theoretical and empirical premises for the possibility of influencing compensatory brain activity in older adults by cognitive training. In the most comprehensive way the phenomenon of compensatory brain activity in older adults is addressed by the STAC model – the Scaffolding Theory of Aging and Cognition, which also provides the theoretical grounds for the possible impact of cognitive training on compensatory brain activity. There are also empirical arguments in favour of such an impact, but they are quite limited in nature. The reason for this is the lack of research directly addressing the problem of the consistency of brain activity changes resulting from cognitive training with the assumptions of compensatory brain activity models, such as STAC. The theoretical grounds for the linkage of compensatory brain activity in older adults with the influence of cognitive training are clear. However, the analysis of the studies discussed in the article suggests that failing to embed the study design within the theoretical framework of compensatory brain activity in older adults may lead to the exclusion of factors important in drawing conclusions about this phenomenon. The following elements of the study design were identified as necessary to include: participation of young adults in the study as a reference group, usage of tasks in different difficulty levels during the measurement of brain activity and consideration of the relation between brain activity and cognitive performance, and comparison of brain activity in relation to cognitive performance before and after training in both, older and young adults.

Cognitive interventions, especially cognitive training, may improve cognitive functions in healthy older adults. Computerized cognitive training platforms offer several advantages over traditional programs for cognitive training and stimulation. The focus of this article is the methodology of the studies that apply a particular online training program. We investigate the effectiveness of several studies for cognitive training in healthy elderly people and evaluate reported outcomes and potential bias and what factors determine, influence or contribute to the positive or negative results. The post-intervention scores demonstrate that computerized cognitive training may enhance some cognitive functions and the overall cognitive status but there is need for additional research to prove its effectiveness.

This paper reports the results from a three-years follow-up study to access the long-term efficacy of a cognitive training for healthy older adults and investigates the effects of booster sessions on the cognitive performance of the participants using an innovative analytical approach from information theory. Design: semi-randomized quasi-experimental controlled design. Participants: 50 healthy older adults, (M = 73.3, SD = 7.77) were assigned into an experimental (N = 25; Mean age = 73.9; SD = 8.62) and a passive control group (N = 25; mean age = 72.9; SD = 6.97). Instruments: six subtests of WAIS and two episodic memory tasks. Procedures: the participants were assessed in four occasions: after the end of the original intervention, pre-booster sessions (three years after the original intervention), immediately after the booster sessions and three months after the booster sessions. Results: the repeated measures ANOVA showed that two gains reported in the original intervention were identified in the follow-up: Coding (F(1, 44) = 11.79, MSE = 0.77, p = .001, ηˆG2 = .084) and Picture Completion (F(1, 47) = 10.01, MSE = 0.73, p = .003, ηˆG2 = .060). After the booster sessions, all variables presented a significant interaction between group and time favorable to the experimental group (moderate to high effect sizes). To compare the level of cohesion of the cognitive variables between the groups, an entropy-based metric was used. The experimental group presented a lower level of cohesion in three of the four measurement occasions, suggesting a differential impact of the intervention with immediate and short-term effects, but without long-term effects.

AbstractThe purpose of this study was to determine the immediate effects of cognitive training on healthy older adults and verify the transfer effects of targeted and non-targeted abilities. The design consisted of a semi-randomized clinical controlled trial. The final sample was composed of 80 volunteers recruited from a Brazilian community (mean age = 69.69; SD = 7.44), which were separated into an intervention group (N = 47; mean age = 69.66, SD = 7.51) and a control group (N = 33; mean age = 69.73, SD = 7.45). Intervention was characterized by adaptive cognitive training with 12 individual training sessions of 60 to 90 minutes (once a week). Eight instruments were used to assess effects of cognitive training. Five were used to assess trained abilities (near effects), including: Memorization Tests (List and History), Picture Completion, Digit Span, Digit Symbol-Coding, and Symbol Search (the last four from WAIS-III). Two instruments assessed untrained abilities (far effects): Arithmetic and Matrix Reasoning (WAIS-III). The non-parametric repeated measures ANOVA test revealed a significant interaction between group by time interaction for Picture Completion [F(74) = 14.88, p = .0002, d = 0.90, CLES = 73.69%], Digit Symbol-Coding [F(74) = 5.66, p = .019, d = 0.55, CLES = 65.21%] and Digit Span [F(74) = 5.38, p = .02, d = 0.54, CLES = 64.85%], suggesting an interventional impact on these performance tasks. The results supported near transfer effects, but did not demonstrate a far transfer effects.

BACKGROUND: Cognitive interventions have the potential to enhance cognition among healthy older adults. However, little is known of the factors associated with the joining and participating of older people in group-based multicomponent cognitive training (CT). OBJECTIVES: To explore factors that contribute to joining and regularly practicing CT over 1 year among healthy older adults. DESIGN: A qualitative study. SETTING: Geriatric clinic in Bangkok, Thailand. PARTICIPANTS: 40 nondemented community-dwelling older adults INTERVENTION: The CT of executive functions, attention, memory and visuospatial functions (TEAM-V) program was conducted over 5 sessions, with a 2-week interval between each session. MEASUREMENTS: An inductive qualitative approach, based on semi-structure interviews with 40 healthy older adults, was employed. The interviews explored factors of joining CT at baseline, factors of regularly participating in class at 6 months and at home at 1 year. Data were coded and analyzed using and the thematic analysis approach. RESULTS: After analyzing factors concerning joining CT, 3 core themes emerged: (1) individual characteristics with 3 subthemes of “health status”, “time arrangement”, and “financial status”; (2) individual perceptions with 2 subthemes of “perceived susceptibility to dementia” and “perceived severity of dementia” and (3) encouragement from families and friends. After analyzing factors of practicing CT in class, 3 core themes emerged: (1) program with 3 subthemes of “session”, “group facilitators” and “notification before class”; (2) accessibility with 2 subthemes of “distance” and “transportation” and (3) encouragement from families and friends. After analyzing factors of practicing CT at home, 2 core themes emerged: (1) contents of the training program and (2) encouragement from families and friends. CONCLUSIONS: Increased awareness of holistic factors including older adults’ characteristic and perceptions, support from families and friends and accessibility should be emphasized in planning CT. Designing the content of CT that could be applied or adapted in daily living and effective program components such as a notification system could increase practicing.
