Two experiments investigated whether the conjunctive nature of nontarget items influenced search for a conjunction target. Each experiment consisted of two conditions. In both conditions, the target item was a red bar tilted to the right, among white tilted bars and vertical red bars. As well as color and orientation, display items also differed in terms of size. Size was irrelevant to search in that the size of the target varied randomly from trial to trial. In one condition, the size of items correlated with the other attributes of display items (e.g., all red items were big and all white items were small). In the other condition, the size of items varied randomly (i.e., some red items were small and some were big, and some white items were big and some were small). Search was more efficient in the size-correlated condition, consistent with the parallel coding of conjunctions in visual search.
两项实验研究了非目标项目的联合性质是否会影响对联合目标的搜索。每个实验都由两个条件组成。在这两个条件下，目标项目都是一个向右倾斜的红色条形，周围是白色倾斜条形和垂直红色条形。除了颜色和方向，显示项目在大小方面也有所不同。大小与搜索无关，因为目标的大小在每次试验中随机变化。在一种条件下，项目的大小与显示项目的其他属性相关（例如，所有红色项目都大，所有白色项目都小）。在另一种条件下，项目的大小随机变化（即，一些红色项目小，一些红色项目大，一些白色项目大，一些白色项目小）。在大小相关条件下搜索效率更高，这与视觉搜索中联合的并行编码一致。
