Search targets are typically remembered much better than other objects even when they are viewed for less time. However, targets have two advantages that other objects in search displays do not have: They are identified categorically before the search, and finding them represents the goal of the search task. The current research investigated the contributions of both of these types of information to the long-term visual memory representations of search targets. Participants completed either a predefined search or a unique-object search in which targets were not defined with specific categorical labels before searching. Subsequent memory results indicated that search target memory was better than distractor memory even following ambiguously defined searches and when the distractors were viewed significantly longer. Superior target memory appears to result from a qualitatively different representation from those of distractor objects, indicating that decision processes influence visual memory.
即使搜索目标的查看时间较短,它们通常也比其他物体更容易被记住。然而,目标具有搜索显示中的其他物体所没有的两个优势:在搜索之前它们就被分类识别,并且找到它们代表了搜索任务的目标。当前的研究调查了这两种信息对搜索目标长期视觉记忆表征的贡献。参与者完成了预定义搜索或独特物体搜索,在独特物体搜索中,目标在搜索之前没有用特定的类别标签进行定义。随后的记忆结果表明,即使在定义模糊的搜索之后以及当干扰物的查看时间明显更长时,搜索目标记忆也比干扰物记忆更好。 superior target memory似乎源于与干扰物物体在性质上不同的表征,这表明决策过程会影响视觉记忆。
