ABSTRACT
The attention system can be divided into alerting, orienting, and executive control networks. The efficiency and independence of attention networks have been widely tested with the attention network test (ANT) and its revised versions. However, many studies have failed to find effects of attention network scores (ANSs) and inter-network relationships (INRs). Moreover, the low reliability of ANSs can not meet the demands of theoretical and empirical investigations. Two methodological factors (the inter-trial influence in the event-related design and the inter-network interference in orthogonal contrast) may be responsible for the unreliability of ANT. In this study, we combined the mixed design and non-orthogonal method to explore ANSs and directional INRs. With a small number of trials, we obtained reliable and independent ANSs (split-half reliability of alerting: 0.684; orienting: 0.588; and executive control: 0.616), suggesting an individual and specific attention system. Furthermore, mutual inhibition was observed when two networks were operated simultaneously, indicating a differentiated but integrated attention system. Overall, the reliable and individual specific ANSs and mutually inhibited INRs provide novel insight into the understanding of the developmental, physiological and pathological mechanisms of attention networks, and can benefit future experimental and clinical investigations of attention using ANT.

Inter-network interactions. Pairwise interactions were measured in separate blocks. All interactions of alerting × orienting, alerting × executive control, and orienting × executive control were significant. Specific inter-network relationships were shown in Fig. 1. Error bar shows the 95% confidence interval.

f2: Inter-network interactions. Pairwise interactions were measured in separate blocks. All interactions of alerting × orienting, alerting × executive control, and orienting × executive control were significant. Specific inter-network relationships were shown in Fig. 1. Error bar shows the 95% confidence interval.

Mentions: As shown in Table 3, both main effects and interactions for three pairs of network were extremely significant, indicating strong coordination between networks when the cognitive system operates more than one network. Visualized inter-network interactions could be seen in Fig. 2. Post hoc analysis was not performed because the directional relationship analysis had described INRs in detail.
