We challenge the role of the oculomotor system in discriminating features during saccadic target selection. Our data suggest that the onset latency of oculomotor vector representations is scaled by task difficulty and featural complexity, suggesting that featural computations are performed outside of the oculomotor system, which receives the output of these computations only after sufficient visual and cognitive processing. We also challenge the convention that initial oculomotor vector representations are feature invariant, as they encoded task relevance.
