    • -5; group comparisons, P < 0.05). For shape search, there was no reliable method to measure perceptual similarity among shapes. However, consistent with the results in color search, the monkeys showed significant differences in fixations on distracters depending on the shape of the searched-for target.

    • Across the population, there were no significant differences in either the average fixation number or the relative contribution of the first fixation after array onset to the data used in comparing the four conditions of interest for each visual search.

    • Forty-four neurons (in 23 sessions) contributed to the analysis of feature enhancement during color search based on significant color selectivity for the two color cues used, and 38 neurons (in 21 sessions) contributed to the analysis of feature enhancement during shape search based on significant shape selectivity. Sixty-one and 57 LFP signals contributed to the analyses of color and shape search, respectively.

    • We calculated the coherence between spikes on one electrode and the LFP recorded on all other electrodes separately. It made no difference in the overall results whether the LFP from the same electrode was used or not, and therefore we included it in our analyses.

    • Of these neurons, 15 contributed to the analysis of color enhancement and 16 to the analysis of shape enhancement.

    • Using the conjunction search data, we found that the lack of saccadic enhancement in the spike-field coherence was not dependent on the properties of the RF stimulus.
