AbstractMoving in and out of small cavelike structures is a common daily activity of Colostethus palmatus. Such sites are used for shelter and spawning. Therefore, cave quality is important to survival and reproductive success. The frogs' association with caves was studied in a 24-cave communal paludarium. Adult frogs recognised cave quality, and chose large damp caves for spawning, but large, wet and dark caves were preferred for shelter, while small ones were used less or ignored. The search time needed to find an available cave gradually shortened over trials, reaching a minimum in about eight days, indicating that frogs learned cave position. Males and females had similar search times. Frogs less familiar with the test area had longer initial search times than frogs with more experience, but achieved equally short search times after about eight days. In conjunction with previous findings the results suggest that visual cues are important in habitat choice and spatial learning, and that territorial and reproductive behaviour are intimately associated with learning performance.

Abstract Japanese eels (Anguilla japonica) were trained on a Morris-type spatial learning task. There were four tubes in a pool, but the eels could hide in only one of these. The eels learned the position of the open tube, and maintained their performance when the pool was rotated to remove possible intra-maze cues. The eels could not maintain their performance in a dark room, suggesting that spatial learning involved extra-maze visual cues. When the position of the open tube was randomly changed every day, the performance of the eels in finding the open tube did not improve.

THE VISUAL CUES USED TO EVALUATE OTHER PEDESTRIANS; FACE, BODY, OR SOMETHING ELSE?

The Face

In subsidiary roads, lighting is installed to meet the needs of pedestrians after dark for safety and their feeling of safety. One aspect is the need to evaluate other people to inform the approach-or-avoid decision. To investigate how changes in lighting matter for this task, we first need to know where people tend to look. Much past work assumes the face is the critical target but this assumption has yet to be tested. A pilot study suggested ability to see the hands and face were significant cues, but did not enable their separate contributions to be identified. This paper describes a second experiment conducted to compare the effect of changes in face and hand concealment on evaluations of safety. The results suggest significant differences between levels of face concealment but smaller differences for changes in hand concealment. The findings from both experiments support the importance of the face for evaluating other pedestrians.

SUMMARYParasite modification of host behaviour influences a number of critical responses, but little is known about the effects on host spatial abilities. This study examined the effects of infection with the intestinal trichostrongylid nematode, Heligmosomoides polygyrus, on spatial water maze learning by male laboratory mice, Mus musculus. In this task individual mice had to learn the spatial location of a submerged hidden platform using extramaze visual cues. Determinations of spatial performance were made on day 19 post-infection with mice that had been administered either 50 or 200 infective larvae of H. polygyrus. The infected mice displayed over 1 day of testing (6 blocks of 4 trials) significantly poorer acquisition and retention of the water maze task than either sham-infected or control mice, with mice that had received 200 infective larvae displaying significantly poorer spatial performance than individuals receiving 50 larvae. The decrease in spatial learning occurred in the absence of either any symptoms of illness and malaise, or any evident motor, visual and motivational impairments. It is suggested that in this single host system the parasitic infection-induced decrease in spatial learning arises as a side-effect of the host's immunological and neuromodulatory responses and represents a fitness cost of response to infection.
