Breaking the waves: Age differences in electrical brain activity when reading text with distractors.
The authors tested whether older adults have greater difficulty than younger adults in ignoring task-irrelevant information during reading as a result of age-related decline in inhibitory processes. Participants were shown target sentences containing distractor words. They were instructed to read aloud each sentence and ignore distractors. The N400 event-related potential (ERP) was used to measure the extent of semantic processing of target and distracting information. It showed that younger adults semantically processed both target and distracting material, whereas online processing of target sentences in older adults was disrupted by the distractors. In older adults, memory for target information related to their susceptibility to distraction and inhibition efficiency. Implications for age-differences in inhibitory control, working memory, and resource capacity are discussed.
Sciences and technology study and technological jobs are deserted by girls. Many measurements were set up in the study to find an issue. But not enough researches learn over this question as part of education study, in other words on the process of transmission. Indeed they ignore for instance, if certain contents, certain types of activities, certain forms of studies, certain gestures of education and scholastic shapes are better adapted to the girls than to the boys and conversely. This article is centred on these aspects and more precisely on artefacts used to mediatise the education of technology. The teacher choice of aids is made in mainly for the pedagogic interest which the object gives. Is the pedagogic interest balanced from the point of view of the question of gender if artefacts introduced in class favour objects which are, in social life, mainly used by men, women or both?
