To gauge the interaction of real-world sonar-task experience and age on brain electrical activity, the effect of sonar experience and age on event related potentials (ERP) was examined. A three-group design was used and the results suggest that sonar experience and age affect the amplitude and distribution of the ERP component. The results concerning age and ERPs support and extend the results of previous studies and suggest that age-related differences occur at a much younger age than is reported elsewhere. Attentional and stimulus evaluation processes which have been linked to parameters of the ERP component may be enhanced with real-world auditory task experience. Research on ERP should control for the possible confounds of auditory-task experience and age.

Conceptual Processing

This paper begins with a brief description of a theoretical framework for semantic memory, in which processing is inherently sensitive to the varying typicality of its representations. The approach is then elaborated with particular regard to evidence from semantic dementia, a disorder resulting in relatively selective deterioration of conceptual knowledge, in which cognitive performance reveals ubiquitous effects of typicality. This applies to frankly semantic tasks (like object naming), where typicality can be gauged by the extent to which an object or concept is characterized by shared features in its category. It also applies in tasks apparently requiring only access to a ‘surface’ representation (such as lexical decision) or translation from one surface representation to another (like reading words aloud), where typicality is defined in terms of the structure of the surface domain(s). The effects of surface-domain typicality also appear early in the time course of word and object processing by normal participants, as revealed in event-related potential studies. These results suggest that perceptual and conceptual processing form an interactive continuum rather than distinct stages, and that typicality effects reign throughout this continuum.

Background Few studies of cognitive rehabilitation in multiple sclerosis (MS) have targeted working memory specifically. Objective We examined the effects of n-back working memory training on cognitive performance and brain function in patients with MS. Methods Patients with MS ( n = 12) and healthy controls (HC; n = 12) underwent 20 sessions of n-back working memory training. Before and after training (pre- and posttest) cognitive event-related potential (ERP) measures were obtained during a 3-back task. In addition, a battery of cognitive tests was administered. Results Following n-back training, both MS patients and HCs showed significant improvement on tests of working memory, processing speed, complex attention, and reasoning ability. MS and HCs also exhibited an enhancement of N2 ERP component amplitude, and earlier N2 and P3 latencies, following n-back training. Conclusions Targeted training of working memory with the n-back task may improve cognitive function in MS. Enhancement of N2 ERP component amplitude and shorter N2 and P3 latency following training in patients with MS is consistent with plasticity of neural processes that are involved in working memory.

Back Task

This study aimed to compare the cognitive performance and event-related potential (ERP) patterns between females who have given birth (parous) and those who have not (nulliparous). A total of 50 female participants, including 27 who were parous (33.2 ± 3.2 years) and 23 who were nulliparous (30.8 ± 2.3 years), were recruited. Only parous females who were ≤36 months postpartum (17.7 ± 8.1 months) were included. To compare the cognitive performance between the two groups, we presented the 3-back task (a working memory task) and compared the accuracy rate (%) and reaction time (ms) between the groups. Electroencephalogram (EEG) signals were simultaneously recorded and the ERP patterns at Fz, Cz, and Pz, which are highly associated with the 3-back task, were analyzed. From the ERP patterns, we extracted N100, P300, P600, P300 peak-to-peak (P300p_p), and P600 peak-to-peak (P600p_p). There were no significant between-group differences in terms of accuracy rate, reaction time, or ERP components (N100, P300, P600, P300p_p, or P600p_p) at the three sites (Fz, Cz, and Pz). Since this study, using meaningful objective data, did not show that parity was significantly correlated with cognitive performance ability and ERP patterns, childbirth does not appear to influence cognitive decline.
