ジャーナル フリーPreference in using one eye or both in terms of integrating visual information was investigated in 11 pigeons. Subjects were trained to peck 8 light emitting diodes (LED) within a specified range. After reaching the desired criterion, they were tested in three viewing conditions; binocular, monocular-right and monocular-left. A black electrical tape was used to occlude vision on one side. Both the latency of response and peck location accuracy were taken as behavioral parameters. Results showed that pigeons pecked significantly better and faster when both eyes were open than when only one eye was being used (either left or right). There was no difference recorded between the left and the right viewing conditions. The superiority of the two-eye condition was explained in terms of the probability principle and the overlap of the two visual fields.抄録全体を表示PDF形式でダウンロード (836K) -

ジャーナル フリーPerformance of adult common treeshrews (Tupaia glis) in an 8-arm and a 16-arm enclosed radial maze was investigated. In Experiment 1, four males and one female treeshrews were trained in the 8-arm maze for 20 days. They improved in choosing an unvisited baited arm during training, and reached a level significantly better than chance in the second 10-day period.Most subjects often ran to the next arm 45 degrees apart from the previously chosen one. Selection of the adjacent arm was more frequent after correct than incorrect response and decreased as the succession of arm entries on the daily trials. In Experiment 2, the same subjects were shifted to the 16-arm maze and trained similarly. They did not show any reliable improvement, but displayed a tendency to choose the next arm next to the chosen one (45 degrees apart). In Experiment 3, delay and cue-utilization tests were given to three of the five subjects again in the 8-arm maze. The results revealed that they dominantly used extramaze cues and suggested the poor level of their spatial working memory ability.抄録全体を表示PDF形式でダウンロード (2409K) -
