Several explanations for the weak relations between subjective memory judgements and objective memory performance were investigated in two groups of normal older adults. Group 1 sampled a general population (mean age 61.6 yr., range 46-89), while Group 2 sampled subjects who were on a waiting list for memory training (mean age 63.0 yr., range 45-85 years).(More)
Self-evaluations by adults (varying in age from 45-92 years) of their memory and learning abilities were investigated and related to performance on laboratory and ecological memory tasks. Hardly any association was found between subjective and objective measures. Self-evaluations were strongly influenced by (systematically varied) frames of reference:(More)
After severe traumatic brain injury, patients almost invariably demonstrate a slowing of reaction time, reflecting a slowing of central information processing. Methodological problems associated with the traditional method for the analysis of longitudinal data (MANOVA) severely complicate studies on cognitive recovery. It is argued that multilevel models(More)
While eLearning systems become more and more popular in daily education, available applications lack opportunities to structure, annotate and manage their contents in a high-level fashion. General efforts to improve these deficits are taken by initiatives to define rich meta data sets and a semantic Web layer. In the present paper we introduce Hylos, an(More)
Does memory strategy training improve the quantity and quality of reported strategy use of normal older adults (N = 111, mean age 63 years, range 46-85 years) in daily life? Three strategy training conditions, remembering names (N = 26), intentions (N = 20) and verbal information (N = 20) and an educational training (N = 23) were compared to a test-retest(More)
The assessment of fitness to drive in patients with closed head injury (CHI) does not usually include executive functioning. Executive functions may be particularly important for the tactical (e.g. anticipatory adaptation of speed) and strategical (e.g. choice of route and time) aspects of driving. The literature lacks evidence on the tactical aspects,(More)
The frequency and preference of memory strategies were investigated in a group of independently living older adults (N = 111, 45-85 year) who were interested in memory training because of subjective and objective memory problems. Mokken scale analysis identified, besides the use of 'no strategy', four strategy scales, viz. encoding, retrieval, general, and(More)
The study aimed to assess the strength of age effects on both standard laboratory and ecological memory tests and the psychometric qualities of these tests. Furthermore, norm data are constructed. Memory performance was assessed in a random group of older adults (mean age 62 years, range 46-89) and a group of older adults having memory complaints who(More)
In this study, a memory training program for remembering names was developed. It was assumed that names are remembered better if they have meaning. The effect of training is compared with two control conditions a) a placebo training, aimed at reducing worries about forgetfulness by giving information about memory and aging and b) a retest control group.(More)
The influence of health-related incidents on memory test performance and subjective memory ratings was assessed in a) a group of healthy older adults recruited via the register of population (group 1: N = 117, mean age 62 years, range 46-89) and b) a group of healthy older subjects having memory complaints and applying for memory training (group 2: N = 111,(More)
