The first row is the variable name. The variable are:</p> <p>1) "live_row"<br>- type: &nbsp;integer numbers, sequential;<br>- values: the index (order) of each SRT measurement performed in a body position, by a participant (ID). The value is C-based (first measurement is "0", second measurement is "1", etc).</p> <p>2) "response_time"<br>- type: real numbers, continuous values;<br>- values: response time recorded from the participant; values in miliseconds.</p> <p>3) "target_position_x_deg"<br>- type: real numbers, categorical (4 values: +/- 18.478, +/- 0.75);<br>- values: horizontal visual angle, in visual degrees in the visual field, of the position of the stimulus. Screen coordinates are computed from "0" position, foveal fixation, positive values to the right, negative values to the left.</p> <p>4) "target_position_y_deg"<br>- type: real numbers, categorical (2 values: &nbsp;-0.75, -7.654);<br>- values: vertical visual angle, in visual degrees in the visual field, of the position of the stimulus. Screen coordinates are computed from "0" position, foveal fixation, positive values downward, negative values upward.<br>-Note: For the equivalent polar coordinates (as in planimetry testing) see Figure 2 of the mentioned paper.&nbsp;</p> <p>5) "Contrast_Weber_calibrated"<br>- type: real numbers, categorical (2 values: &nbsp;50.58, 99.3);<br>- values: Measured Weber contrast of the visual stimulus shown, values in percents.</p> <p>6) "hand"<br>- type: categorical, 1 value ("right");<br>- values: hand used by the participant during SRT task.</p> <p>7) "body_position"<br>- type: categorical (4 values: "vertical (90 deg)", "horizontal (0 deg)", "inclined (-6 deg)", "inclined (-15 deg)" );<br>- values: Body position during the SRT task.</p> <p>8) "ID(anon)"<br>- type: integer number, categorical, 8 values;<br>- values: anonymized ID of the participants in the study (8 persons).</p>
