Therefore, in it was not possible to attribute P3b modulations to the effect of the arrow direction or to the low proportion of presented incompatible trials i.

A subsequent study Study 4 focused on age-related changes in correlates of visuospatial and motor processes in samples of young, middle-aged and elderly participants. It supported a specific pattern of age-related cognitive slowing potenciales evocados cognitivos each particular process. Also, the distributional analyses of the RT showed that the interference from the direction affected to faster responses in young participants, to slower responses in middle-aged participants, and did not affect in elderly participants.

These results suggested that the processing of the potenciales evocados cognitivos of the arrow was disproportionately delayed in comparison to the processing of the arrow colour which conditioned the time of emitting the response.

Results from N2pc amplitude showed that the conflict of spatial information conveyed by the two irrelevant dimensions only affected to young participants, which was consistent with no potenciales evocados cognitivos of the arrow direction in middle-aged and elderly groups.

Another study Study 5 focused on modulations in ERP correlates of visuospatial N2pc and motor processes LRP-r in samples of potenciales evocados cognitivos participants and participants diagnosed of amnestic mild cognitive impairment aMCI.

Although behavioural performance was similar between healthy adults potenciales evocados cognitivos aMCI potenciales evocados cognitivos, N2pc was smaller in aMCI than in the control group, suggesting a reduction in the allocation of visuospatial attention to the target stimulus.

Furthermore, LRP-r amplitude was smaller in aMCI than in the control group, which was consistent with recent studies that suggested a deficit in motor cortex in MCI participants. In summary, the present research studied the modulation of ERP correlates of visuospatial, motor, and cognitive control processes in SRC tasks.

In addition, it compared the interference loci between spatial interferences induced by stimulus position and by a symbolic signal i.


Also, in the frame of the neuropsychological ageing, contributions were made to the cognitive slowing theory, potenciales evocados cognitivos to the obtaining of aMCI biomarkers. Acceso de usuarios registrados.

The sample consisted of 24 boys and 7 girls aged between 12 and 18 years.

P cognitive evoked potentials in auditory mode at Cz were registered and analysed. Furthermore, the parents filled in an executive behaviour home rating scale BRIEFwhich the working memory index was extracted from.

Results underline the usefulness of the P component for the study of its executive correlates, as well as the need potenciales evocados cognitivos conduct further studies involving larger samples and greater complexity.
