abstract="On an auditory attention task subjects were required to reproduce spatial relationships between letters from auditorily presented verbal information containing the prepositions &quot;before&quot; or &quot;after.&quot; It was assumed that propositions containing &quot;after&quot; induce a conflict between temporal, and semantically implied, spatial order between letters. Data from 36 subjects showing that propositions with &quot;after&quot; are more difficult to process are presented. A significant, general training effect appeared. 200 mg caffeine had a certain beneficial effect on performance of 18 subjects who had been awake for about 22 hours and were tested at 6 a.m.; however, the beneficial effect was not related to amount of conflict but concerned items without and with conflict. On the other hand, the effect of caffeine for 18 subjects tested at 4 p.m. after normal sleep was slightly negative.<p /><p>Language: en</p>",
