本研究探讨了视觉阵列中固有的结构性差异在多大程度上有助于引导目标检测，并减少与年龄相关的差异，熟练的视觉搜索性能。目标检测性能的医学实验室技术人员在2个年龄组（M = 24.3岁和M = 49.0岁）和年龄匹配的新手进行了评估，使用革兰氏染色显微照片作为目标和搜索阵列的细菌形态的图像。对于熟练的观察员，响应时间较长的中年人比年轻的成年人，除了当外部位置线索可用，或当阵列中固有的上下文线索可用于指导目标检测。这些结果表明，上下文信息援助的中年专家熟练的搜索，并建议，上下文线索是我的意思，中年人可以规避的影响，通常年龄不足的过程中的性能在一个熟练的域。
This study examined the extent to which structural regularities inherent in visual arrays help to,guide target detection and reduce age-related differences in skilled visual search performance. The target-detection performance of medical laboratory technologists in 2 age groups (M = 24.3 years and M = 49.0 years) and age-matched novices was assessed using images of bacterial morphology taken from Gram's stain photomicrographs as targets and search arrays. For skilled observers, response times were longer for middle-aged adults than for young adults except when external location cues were available, or when contextual cues inherent in the array were available to guide target detection. These results demonstrate that contextual information aids the skilled search of middle-aged experts, and suggest that contextual cuing is I means by which middle-aged adults can circumvent the effects of normally age-deficient processes on performance in a skilled domain.
