Abstract
This chapter explores the effects of contextual and instructional manipulations on visual search behavior in a conjunctive search task with a distracter-ratio manipulation. Participant's eye movements were monitored when they performed the task. Results from the investigation demonstrated that block context modulates the temporal dynamics of visual search by shortening fixation durations, reducing the number of fixations, enhancing task-relevant subset selection, and as a result, yielding faster manual responses in those trials that were congruent with the block context than in incongruent trials. This chapter suggests that the presence of top-down influences associated with an instructional manipulation operates over and above any influences of context.
