| Popis: | Most students of search behavior record eye motion while S scans an aerial photograph or a blank visual field. It is difficult to correlate the continuous search record with the unstrucrured fields. In multiple choice experiments, however, the field to be searched is well defined as a small set of discrete alternatives, encouraging a probabilistic analysis. This study introduces a search task in which the field to be searched is a large set of alternatives arranged in a matrix. As in the popular game of "battleship," S sequentially searches rhe matrix cells seeking those cells that contain stationary rargets. In this experiment, Ss individually searched a 400-cell matrix for a onecell target under three sets of restrictions. One group had complete freedom of movement, moving from any cell to any cell. A second group could move only into adjoining cells. A third group had the same freedom of movement as the first, but Ss could not record heir moves. The performance of Ss under each condition was compared wirh the hypothesis that search would be random. Observations were also made on the rules, adopted by Ss who lacked a search record, to avoid re-searching. |
