Última Experimental context modulates warning signal effects BJMBR Machado-Pinheiro,W.; Faria Jr.,A.J.P.; Gawryszewski,L.G.; Ribeiro-do-Valle,L.E.. Previous studies have shown that saccadic eye responses but not manual responses were sensitive to the kind of warning signal used, with visual onsets producing longer saccadic latencies compared to visual offsets. The aim of the present study was to determine the effects of distinct warning signals on manual latencies and to test the premise that the onset interference, in fact, does not occur for manual responses. A second objective was to determine if the magnitude of the warning effects could be modulated by contextual procedures. Three experimental conditions based on the kind of warning signal used (visual onset, visual offset and auditory warning) were run in two different contexts (blocked and non-blocked). Eighteen participants were asked to... Tipo: Info:eu-repo/semantics/other Palavras-chave: Reaction times; Attention; Distractor; Preparation; Expectancy.
