本研究调查了对相关项目进行分组如何导致视觉搜索中出现收益(当相关项目是搜索目标时的促进)和成本(当相关项目是干扰项时的干扰)。参与者通过以下方式整合新的乐高©物体的不同视图(“相关项目”):1)组装物体,2)拆卸物体,或3)在没有明确指示的情况下安静地坐着。综合方差分析显示,无论训练条件如何,当特定目标视图出现时(收益)以及当来自与目标视图的同一对象的非目标视图出现时(成本),在前测和后测之间,注意选择的神经反应(N2pc 事件相关电位)都会增加。 Bonferroni 校正的计划比较显示,组装对象(但不拆卸对象或不进行训练)从预测试到后测试具有显着影响,尽管方差分析没有揭示任何交互效应,这表明这些效果在不同训练条件下可能没有差异。这项研究是第一个证明将新目标分组对视觉搜索效率的成本和收益的研究之一。
The present study investigated how grouping related items leads to the emergence of benefits (facilitation when related items are search targets) and costs (interference when related items are distractors) in visual search. Participants integrated different views (“related items”) of a novel Lego© object via 1) assembling the object, 2) disassembling the object, or 3) sitting quietly without explicit instructions. An omnibus ANOVA revealed that neural responses (N2pc event-related potential) for attentional selection increased between pretest to posttest regardless of the training condition when a specific target view appeared (benefit) and when a nontarget view from the same object as the target view appeared (cost). Bonferroni-corrected planned comparisons revealed that assembling the object (but not disassembling the object or no training) had a significant impact from pretest to posttest, although the ANOVA did not reveal any interaction effects, suggesting that the effects might not differ across training conditions. This study is one of the first to demonstrate the emergence of the costs and benefits of grouping novel targets on visual search efficiency.
