在3个实验中检验了Eriksen和Yeh(CW Eriksen和Y.-Y.Yeh，1985)视觉搜索注意分配模型的修订版。结果证实了模型的假设，即表现为集中注意和分布式注意试验的加权组合，尽管SS对集中注意的依赖比预测的更多。与该模型一致的是，基于终止搜索假设的预测比基于穷举搜索的预测更符合数据。不同线索有效性的影响更倾向于用加工梯度而不是变焦镜头来解释聚焦注意。尽管年轻人和老年人在试验中的注意力分配相似，但在个别试验中分配注意力所需的时间随着年龄的增加而增加。(心理信息数据库记录(C)2016 APA，保留所有权利)
Examined in 3 experiments a revised version of the Eriksen and Yeh (CW Eriksen and Y.-Y. Yeh, 1985) model of attentional allocation during visual search. Results confirmed the assumption of the model that performance represents a weighted combination of focused-and distributed-attention trials, although Ss relied on focused attention more than was predicted. Consistent with the model, predictions on the basis of the assumption of a terminating search fit the data better than predictions on the basis of an exhaustive search. The effects of varying cue validity favored an interpretation of focused attention in terms of a processing gradient rather than a zoom lens. Although the allocation of attention across trials was similar for young and older adults, there was an age-related increase in the time required to allocate attention within individual trials.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
