Regularities in a display are learned implicitly and facilitate visual search performance (contextual cueing). We examined what processes in visual search is necessary for learning contextual cue, using a new paradigm where a visual search task and a go/no-go task were combined. Participants were asked to search for a target (a square that had a gap on the right or left side) among distractors (squares that has a gap on the top or bottom). Each search item contained a digit (from 0 to 9). The participants had to discriminate which odd or even a digit in a target was and, only when the digit was even, to answer which side a gap of the target was on. Forty-eight layouts were generated at the beginning of the experiment and repeated across 20 learning blocks. In the half of the layouts, the targets always contained an even digit (repeated go layouts). In the remaining half, the targets contained an odd digit (repeated no-go layouts). The results showed that comparative amount of the contextual cueing effects were observed both in the go and no-go layouts, suggesting that detection of a target is sufficient for learning contextual cue, rather than making a response to a target.
