Besides, two distracting stimuli fillers were presented at the outset of the block and discarded afterwards, so that the measurement of the mean times RT would not be affected by problems unrelated to the studied process such as the habituation to the task. The other stimuli were presented randomly.
De este modo, los estímulos en modalidad causal, se respondían con “sí” mientras los estímulos en modalidad contracausal se respondían con “no”, por lo que el tipo de respuesta esperada también se encontraba equilibrada dentro de cada bloque.
