Implicit sequential learning using Stroop task

The research investigated the implicit sequential learning under the condition in which Stroop task was used. A stimulus of color name printed in incongruent color was presented on CRT monitor on each trial. The task was naming the color in which the word was printed. The color names were presented randomly and the printed colors were presented according to either a high structured or a low structured sequence. The learning of both sequences was observed when assessed through performance measure (decrease or increase in reaction times). The learning may be said to have occurred implicitly since the subjects trained under the low structured sequence proved to be almost unaware of the nature of the sequence and they performed no better than control subjects in a cued-recall task (generate the sequence). These results are considered important in examining the conditions in which sequential events can be learned implicitly.
