Abstract
Ocean waves cause oscillatory motion of ships. Oscillatory ship motion typically is greater in roll
(i.e., the ship rolling from side to side) than in pitch (i.e., tipping from front to back). Affordances
for walking on a ship at sea should be differentially influenced by ship motion in roll and pitch.
When roll exceeds pitch, the maximum walkable distance within a defined path should be greater
when walking along the ship’s short, or athwart axis than when walking along its long, or fore-aft
axis. When pitch exceeds roll, this relation should be reversed. We asked whether such changes
in ship motion would be reflected in judgments of direction-specific affordances for walking. Participants
(experienced maritime crewmembers) judged how far they could walk along a narrow
path on the ship deck. On different days, sailing conditions were such that the relative magnitude
of pitch and roll was reversed. Judgments of direction-specific affordances for walking mirrored
these changes in ship motion. The accuracy of judgments was consistent across directions, and
across changes in ship motion. We conclude that experienced maritime crewmembers were sensitive
to dynamic variations in affordances for walking that were, themselves, a function of dynamic
properties of the animal-environment system.
