The attentional blink (AB) is often attributed to resource limitations, but the nature of these resources is commonly underspecified. Recent observations rule out access to short-term memory or storage capacity as limiting factors, but operation bottlenecks are still an option. We considered the operation span of working memory (WM) as a possible factor and investigated the relationship between individual WM operation span (as measured by OSPAN), fluid intelligence (as measures by Raven's SPM), and the size of the AB. WM operation span was negatively correlated with the AB, whereas fluid intelligence was associated with higher overall accuracy but not with AB magnitude. These results support the idea that individual processing limitations (with regard to either attentional allocation policies or the speed of global cortical integration processes) play a key role in the AB.
注意瞬脱（AB）通常归因于资源限制，但这些资源的性质通常未明确说明。最近的观察结果排除了短期记忆访问或存储容量作为限制因素，但操作瓶颈仍是一种可能。我们将工作记忆（WM）的操作广度视为一个可能因素，并研究了个体WM操作广度（通过OSPAN测量）、流体智力（通过瑞文标准渐进矩阵测量）与AB大小之间的关系。WM操作广度与AB呈负相关，而流体智力与更高的总体准确性相关，但与AB幅度无关。这些结果支持了这样一种观点，即个体加工限制（无论是注意力分配策略还是整体皮层整合过程的速度）在AB中起关键作用。
