Methods for the Follow-Up Study: Wall Orientation

Trial Sequence --- Condition Type --- Participants --- Box Layouts --- Raw Data

Trial Sequence:

Top

Step 1: Interval 1: Participants were standing at start zone , and were looking at a blue, a pink, a red and a yellow box. They were asked to memorize where the boxes were, and could take as much time as they need. The whole scene disappeared if the participant stepped out of start zone. They were told that the blue and the pink box, as well as the red and the yellow box were always in the same visual direction no matter which box layout as viewed from start zone.

Step 2: Participants now pressed a button, a long or short horizontal wall - depending on which condition type (see this section) they were tested in - appeared in front of them. The four boxes are now not visible. A white poster on the wall indicated the participant were to walk and stop.

Step 3: Participants walked to the poster, and stopped either at zone b - like the colour black , at zone c - like the colour cyan , at zone d - like the colour damson , or at zone e - like the colour evergreen . At these shooting zones, the participant could not see the 4 boxes any more. As soon as participant entered the zone, interval 2 started.

Step 4: Interval 2: Participants now used a hand-held pointer to shoot 6 times to each of the 4 boxes in a random order, which gave us 24 shooting directions.

Condition Type 11/12: Participants were standing at start zone , and were looking at the four boxes with a vertical wall parallel to the line subtended by the pink and the blue box. After a button press, the grey dotted, horizontal wall appeared in front of the participant. As soon as participant left start zone, the black dashed-dotted long vertical wall appeared, and they walked to either zone b or zone c .

Condition Type 21/22: Participants were standing at start zone , and were looking at the four boxes with a slanted wall parallel to the line subtended by the red and the yellow box. After a button press, the grey dotted, horizontal wall appeared in front of the participant. As soon as participant left start zone, the black dashed-dotted long slanted wall appeared, and they walked to either zone d or zone e .

Condition Type 41/42: Participants were standing at start zone , and were looking at the four boxes with a slanted wall parallel to the line subtended by the red and the yellow box. After a button press, the grey dotted, horizontal wall appeared in front of the participant. As soon as participant left start zone, the black dashed-dotted long slanted wall appeared, and they walked to either zone b or zone c .

Participants:

Top
  • Every participant is tested TWICE on each condition type, on each box layout.
  • Planned: 10 participants (regardless of gender or age)

Box Layouts:

Top

There are 4 different box layouts (0, 1, 8, 12), each box layout was tested at the six different condition types in virtual reality. The blue and the pink were in the same visual direction as viewed from start zone , the same for the red and the yellow box.
