Should 'Cyrus the Centipede' take a hike? Effects of exposure to a pedestrian safety program on children's safety knowledge and self-reported behaviors

INTRODUCTION: We report the first evaluation of the popular "Cyrus the Centipede" child pedestrian safety program. METHOD: A pre-test/post-test control versus experimental condition design was used to assess Cyrus' impact on third graders' pedestrian safety knowledge, and self-reported pedestrian behaviors. RESULTS: Although some beneficial effects were observed, the program was not reliably effective. In particular, the impact of exposure to Cyrus was strongly influenced by the individual teacher who delivered it, likely due to the highly unstructured nature of the curriculum. SUMMARY: We suggest that: (a) the effectiveness and reliability of such programs be demonstrated before they are widely adopted; and (b) programs that focus on training children in actual or simulated traffic environments may be more effective than those that primarily focus on teaching safety facts and rules.

Anti-predator behavior of group-living Malagasy primates: mixed evidence for a referential alarm call system

Many mammals warn conspecifics with alarm calls about detected predators. These alarm calls are either functionally referential, urgency based, or they can have multiple functions, including predator deterrence. The taxonomic distribution of these alarm call systems is uneven, with primates providing the best-known examples for a functionally referential system and rodents most examples of an urgency-based system. Reports of different alarm call systems in lemurid primates prompted us to examine the anti-predator behavior of two additional lemur species. In an experimental field study we exposed adult redfronted lemurs (Eulemur fulvus rufus) and white sifakas (Propithecus verreauxi verreauxi) to playbacks of vocalizations of their main aerial and terrestrial predators, as well as to their own alarm calls given in response to the presentation of these predators. We scored the subjects' immediate behavioral responses, including alarm calls, from video recordings made during the first minute following a playback. We found that both species gave specific alarm calls only in response to raptor playbacks and the corresponding alarm calls, whereas calls given in response to carnivores and the corresponding alarm calls were also observed in other situations characterized by high arousal. Other behavioral responses, such as gaze and escape directions, corresponded to the hunting strategies of the two predator classes, suggesting that the corresponding vocalizations were categorized correctly. These two lemur species, which represent different families, have therefore independently evolved a mixed alarm call system, characterized by functionally referential calls for diurnal raptors, but not for carnivores.
