Comparing saccadic and manual responses in the attention network test.

Area of Science:

• Cognitive Neuroscience
• Neuroscience
• Psychology

Background:

• Attention is understood as multiple functional networks: alertness, orienting, and executive control.
• The Attentional Networks Test (ANT) is a common tool for studying these networks.
• The role of eye movements (oculomotor system) in attention networks remains under-explored.

Purpose of the Study:

• To investigate the involvement of oculomotor responses in attention networks.
• To adapt the manual Attentional Networks Test (ANTm) for saccadic responses.
• To compare network interactions using manual and saccadic response versions of the ANT.

Main Methods:

• Modified the executive control of the ANTm for oculomotor responses using pro/anti-saccades.
• Conducted three experiments comparing ANTm, ANT with saccadic responses (ANTs), and ANT with central fixation (ANTf).
• Analyzed main effects and interactions of alerting, orienting, and executive control networks.

Main Results:

• All three experiments showed main effects for the attention networks.
• Differences in network interactions were observed across the manual and saccadic response versions.
• The ANT with saccadic responses (ANTs) showed an orienting effect specific to pro-saccades.

Conclusions:

• The proposed ANT with saccadic responses (ANTs) is a valid method for assessing attentional network main effects.
• Significant differences exist in attention network interactions between manual and oculomotor response systems.
• Further research is needed to fully understand manual versus oculomotor system differences in attention.
