(A) Experimental design. Throughout a bar pass participants reported either changes in color (Attend Color) or temporal frequency (Attend TF) of Gabor elements within the moving bar stimulus, or …
(A) Attend Fixation pRF polar angle maps for an example participant with retinotopic areas up to the intra-parietal sulcus defined by hand. (B) Attend Fixation pRF size as a function of eccentricity …
This figure shows that eccentricity-size relations are positive in all ROIs for both the 'super subject' method (Supplementary file 1 - Table 1) and the 'over subjects' method (Supplementary file 1 …
The violin plots depict the distribution of explained variance across voxels for the different ROIs and for all subjects.The horizontal line at 0.10 indicates the exclusion criterion (voxels with …
(A) Plotting strategy. For pRF shift visualizations, all pRF positions are mirrored into one quadrant of the visual field. Then, vectors representing the shift of pRF centers between conditions were …
Shift vectors run from the Attend Fixation to the Attend Stimulus pRF location. This figure indicates that the shift patterns seen in the 'super subject' are almost identical to the 'over subjects' …
The 'over subjects' panel replicates the 'super subject' results, namely that shifts are best explained by eccentricity changes, followed by changes in pRF x and finally in pRF y in all ROIs (see Sup…
The data from all statistical methods closely matches the radial shift direction hypothesis, showing strongest pRF x shifts close to the horizontal meridian, strongest pRF y shifts close to the …
Difference between Attend Stimulus and Attend Fixation pRF eccentricity (A) and size (B) as a function of Attend Fixation eccentricity. Overall, parafoveal pRFs tend to shift away from the fovea and …
Difference between Attend Stimulus and Attend Fixation pRF eccentricity and size as a function of Attend Fixation eccentricity (see Supplementary file 1 -Tables 4-7 and 16-23). The data show a …
In the 'over subjects' method, we find that pRF eccentricity and size changes are significant in all ROIs except IPSO (although p = 0.070). In the 'per subject method', we find such a significant …
(A) Observed (black) and predicted (color) pRF shifts. (B) Observed and predicted changes in pRF eccentricity (the main pRF shift direction) as a function of eccentricity. Markers depict data and …
Arrows depict observed (black) and predicted (color) pRF shifts. This shows that the model closely captured the data in all individual subjects.
Observed (markers) and predicted (solid lines) pRF eccentricity difference between Attend Fixation and Attend Stimulus conditions for each subject. This shows that although individual subjects show …
(A) Differences in pRF eccentricity and size relative to the Attend Fixation condition, for both the Attend Color and Attend TF conditions. The changes in both eccentricity and size are more …
The bottom-right panel shows the feature AMI for all ROIs together for the 'super subject'. This shows that feature AMI is generally positive along eccentricity across ROIs. In addition, differences …
In (A), FAMI only includes the change in pRF size, whereas in (B), FAMI only includes the change in pRF eccentricity. This reveals comparable results to use of the combined FAMI pRF size and …
Differences in pRF eccentricity and size relative to the Attend Fixation condition, for both the Attend Color and Attend TF conditions separately.The changes in both eccentricity and size are more …
The y-axis displays feature AMI, which increases when pRF modulations (size and eccentricity changes combined, see Materials and methods) are greater when attending color compared to TF. The x-axis …
Preference to color compared to TF is greatest near the fovea. Error bars denote 95% CI over voxels. Also see Figure 7—figure supplement 1.
The 'super subject' method shows negative Spearman correlations in all ROIs except VO and LO (see Supplementary file 1 -Table 10). The 'over subjects' method shows that this correlation is negative …
Results are shown for the combined ROI and for the median across ROIs. Positive values here indicate smaller attentional gain fields when attending color compared to temporal frequency in the bar. …
(A) Behavioral accuracy per attention condition and per bar stimulus eccentricity bin. Horizontal line denotes Quest target of 83%; chance level was 50%. (B) Median (top panel) and standard …
In the Attend Color condition, this reflected the ratio of elements that were either blue/yellow or green/magenta. In the Attend TF condition this reflected the ratio of elements that were either …
(A) The Stimulus Drive (SD) was estimated by dividing the measured Attend Fixation pRF by an AF at fixation (). (B) Attention toward the bar stimulus at a given timepoint was modeled as the …
