Words n+1 and n+2 had either correct or incorrect previews prior to fixation (prior to crossing the boundary location). In addition, the manipulation utilized either a high or low frequency word in word n+1 location on the assumption that it would be more likely that n+2 preview effects could be obtained when word n+1 was high frequency. The primary findings were that there was no evidence for a preview benefit for word n+2 and no evidence for parafoveal-on-foveal effects when word n+1 is at least four letters long.

To examine further the range of intellectual reserve available to aging individuals and the question of replicability in a new cultural and laboratory setting, 204 healthy older adults (mean age = 72 years; range = 60-86) participated in a short-term longitudinal training study. For experimental subjects, 10 sessions consisted of cognitive training involving two subability tests (Figural Relations, Induction) of fluid intelligence. The pattern of outcomes replicates and expands on earlier studies. Older adults have the reserve to evince substantial increases in levels of performance in fluid intelligence tests. Transfer of training, however, is narrow in scope. Training also increases accuracy of performance and the ability to solve more difficult test items. Difficulty level was estimated in a separate study, with a comparable sample of N = 112 elderly adults.

Of the original 37 subjects, 35 (16 young, ranging from 20 to 30 years of age, and 19 older adults, ranging from 66 to 80 years of age) participated in the follow-up study. Older adults showed sizable performance deficits when compared with young adults and tested for limits of reserve capacity.

Little is known, however, about the locus of plasticity. Two studies were conducted to examine whether training gains in fluid abilities are critically dependent on experimenter-guided training and/or whether older adults can achieve similar improvements by themselves on the basis of cognitive skills already available in their repertoire. Several comparisons were made: (a) between test performances after trainer-guided training in ability-specific cognitive skills and after self-guided retest practice (without feedback), (b) between performances under speeded and power conditions of assessment, (c) between performances on easy and difficult items, and (d) between the relative numbers of correct and wrong answers. Results suggest that a large share of the training improvement shown by the elderly can plausibly be explained as the result of the activation and practice of cognitive skills already available in their repertoire.

Training time and training materials were held constant for the two training conditions. Posttraining performances were analyzed using a transfer of training paradigm in terms of three indicators: correct responses, accuracy, and level of item difficulty. The training programs were effective and produced a significant but narrow band of within-ability transfer. However, there was no difference between the two training groups.

It has been shown that both attentional demand (i.e., cognitive processing) and fatigue affect postural control in young adults. However, their combined effect is still unresolved. Therefore, we investigated the effects of fatigue on single- (ST) and dual-task (DT) postural control. Twenty young subjects (age: 23.7 ± 2.7) performed an all-out incremental treadmill protocol. After each completed stage, one-legged-stance performance on a force platform under ST (i.e., one-legged-stance only) and DT conditions (i.e., one-legged-stance while subtracting serial 3s) was registered. On a second test day, subjects conducted the same balance tasks for the control condition (i.e., non-fatigued). Results showed that heart rate, lactate, and ventilation increased following fatigue (all p < 0.001; d = 4.2-21). Postural sway and sway velocity increased during DT compared to ST (all p < 0.001; d = 1.9-2.0) and fatigued compared to non-fatigued condition (all p < 0.001; d = 3.3-4.2). In addition, postural control deteriorated with each completed stage during the treadmill protocol (all p < 0.01; d = 1.9-3.3). The addition of an attention-demanding interference task did not further impede one-legged-stance performance. Although both additional attentional demand and physical fatigue affected postural control in healthy young adults, there was no evidence for an overadditive effect (i.e., fatigue-related performance decrements in postural control were similar under ST and DT conditions). Thus, attentional resources were sufficient to cope with the DT situations in the fatigue condition of this experiment.}, language = {en} } @misc{BohnKliegl2008, author = {Bohn, Christiane and Kliegl, Reinhold}, title = {Zur Interaktion von Verarbeitungstiefe und dem Wortvorhersagbarkeitseffekt beim Lesen von S{\"a}tzen}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-57036}, year = {2008}, language = {de} }
